Alluvial gold refers to tiny gold flakes that come to be through water erosion and movement. In geology, alluvium is loose sediment which has been eroded from a primary source, transported and further eroded by water, and redeposited. Since gold is extremely dense, it is easily trapped alongside other dense alluvial particles. The bits of gold found in these deposits of alluvium are called “alluvial gold.”
The alluvial environment is a very complex one, with many natural forces competing with each other. The forces that lay down gold are a summation of many flood water events of varying intensity that cause the reworking of sands and gravels. Between major flood events, water naturally flows along the already created path and typically the gold present in the gravel or on the surface will not move much. But the larger flooding events can change the drainage routes and even the river’s shape. Some curves can be shut off from the stream and bypassed. Where the water speed decreases, gravels will drop out of suspension, creating alluvial pay streaks that are typically located along and near the riverbed.
To identify where a pay streak might be located, take the flow of the waterway into consideration. The most productive streaks are formed as a result of major floods that are significant in terms of both water flow and intensity of erosion. Greater amounts of gold are present here as compared to regular gravels. Pay streaks tend to possess a comet-like form. At the “head” or “heart” is found the richest concentration of gold. At this location, the gravel is coarser and the sandy and silty fraction is much less. This little bit of silt is present only for a few centimeters on the surface, laid down in the last phases of the flood as the silt is dropped. The gold in these gravels is typically small flat flakes, with maybe a small picker or two.
As gold prospectors, our objective is to learn to read a stream and recognize the pay streaks it contains. Think about where you are going to dig before you start and then repeatedly test the gravel you are processing. It is important to consider the presence, form, and depth of the bedrock on which the water and all the alluvial gravel deposits are sitting. In many cases, the gold will naturally concentrate in the lowest part of the riverbed, making a gold-rich path. During high water events, much of the gold is picked up and put back into motion, which leads to forming new pay streaks. Some will be laid back down along the low line of the stream, but may also end up a little farther downstream. The gravels in contact with the bedrock or false bedrock base are often the richest. The same facts apply to the alluvial pay streaks that are formed on gravel bars— the lowest level of the gold-bearing gravel is normally the richest.
The alluvial environment changes over time. Alluvial pay streaks generated 100 years ago could become buried, then subsequently be eroded and exposed again. The erosion might be in part or in total, generating a new series of paystreaks further downstream. Pay particular attention to large boulders and trees. Obstacles like these may partially block the water flow and provide an opportunity for increased gold concentrations, especially behind the obstructions. If there are fissures, holes or natural traps in the stream, be sure to sample these areas, too.
Although high water events are sporadic, when you do find a paystreak caused by one, it can be a very productive spot. Stick with it and keep in mind most are small and narrow and best worked by hand with a sluice and gold pans.

A highbanker, sometimes called a power sluice, is a very flexible and efficient piece of equipment when you’re gold mining in areas with a good amount of water. Their main use is to allow you to pump the water to the gravels rather than carrying heavy buckets of gravel to the water. The optimal place to use a high banker is a location along a river where there are lots of bench gravels that have been left high and dry by erosion. Just shovel material directly into a high banker and let the equipment do the rest of the work! As long as there is sufficient water close by so the hose can reach it, you’ll be good to go. High bankers are available in various sizes. The bigger the unit, the more gravel it will handle in a day. That also means it will likely be heavier and less portable. High bankers are fairly simple to set up and operate. They have three main components: a hopper feed box, and sluice box, and a pump.
Hopper: The feed box contains a grizzly screen with a water spray bar. The water is normally sprayed from simple plastic pipes with a series of small holes drilled into them. A water valve located ahead of the spray pipe controls the amount of water flow going into the feed box sprays. A series of rods are arranged to make a slat-type screen (called a grizzly) that allows water and smaller material to fall through and go down into the sluice box. The large rocks that are caught by the grizzly are washed with the spray and then rejected. The slats should be set on an angle so that most of the larger gravel will slide off the slats by the pull of gravity without you needing to push them off by hand. Some rocks may hang up, but for the most part, they will slide off on their own. The spray water comes out under a lot of pressure and washes any loose sand or clay into the sluice and also provides part of the water needed to move material through the sluicebox area.
Sluice: High bankers utilize a normal sluice to recover the gold from the gravels, and the operation of the sluice box portion of a high banker is basically the same as that of a hand or stream sluice. With a highbanker, the water is supplied by a pump rather than the flowing water of a stream. The matting and miners moss underneath the sluice’s riffles are the same. Gold flakes get caught in the riffles and moss the very same way as it does in a hand sluice. A nice back-saving bonus on a high banker is that it will be on legs, so you can operate it on any terrain. A normal hand sluice lays on the bottom of a streambed.
Pump: The centrifugal type pump should be set near the water as it is more efficient to pump water uphill to the sluice than to suck it up to the pump. This is only important where there is a lot of vertical distance between the pump and the sluice. If there is less than 10 feet of vertical distance, it does not matter much. Pumps can be set up quite a distance away horizontally from the sluice. It will work so long as there is sufficient water at the source where the pump is located. Vertical distance is more of a problem than horizontal distance; 30-40 feet is the maximum vertical climb for most pumps. The standard lay flat type of hose is used to carry the water up to the feed hopper. Be sure to have enough hose and some extra in case you spring a leak! Remember to position the pump so that you aren’t breathing motor exhaust fumes all day!
The big advantage of a highbanker is working materials that are found in a location away from a river, like benches and other isolated patches of gravel. Moving the water to the sluice with a pump saves you from carrying the material down to the stream. The only disadvantage to highbanking for gold might be that it’s more equipment to pack around than just your usual digging equipment. It would be wise to test your ground before hauling in your high banker. Testing will indicate if there is enough gold in the gravels to warrant bringing in more than a hand sluice. If you have at least an amount of gravel that represents a full day of digging and sluicing, bring in a highbanker.
The adjustment of a high banker is much less than the steep slope you usually would use with a hand sluice. Adjust the water flow to the minimum flow rate that it takes to get all the rocks that fall through the screen to keep moving down the sluice box section. If rocks or gravel hang up and bury the sluice, you need more water and perhaps a steeper box angle to wash that stuff away. The height of the feed box is another important adjustment. You want it low to allow you an ease of feeding in the material. If too high, you will hurt your back lifting heavy shovels full of gravel. Too low and you may be constantly sweeping away tailings at the back of the sluice.
The feed box itself should be adjusted to ensure the angle of the slat screen rods (the grizzly) allow the gravel to be well washed before it moves out as waste. This is because a lot of small gold adheres too the larger cobbles. If rocks and cobbles just roll through without getting a thorough washing, you will be losing gold. The rejection of the large oversize rocks is important as it lets your sluice to a better job. If those bigger rocks make it into the sluice, you’ll be getting much worse recovery of fine gold.
Be sure the foot valve or strainer on the intake hose is clear and able to deliver a full water flow. Sometimes the foot valve can get clogged with leaves or other debris. A blocked or partially obstructed foot-valve won’t allow the high banker to operate properly. For environmental reasons, it is a good idea to have your water drain into a pond or pit that is not directly connected to the stream. This is so that the clay and mud can settle out, otherwise make sure there are no legal issues of putting that mud back into a flowing stream.
Some models of highbankers can also be run as a dredge. These highbanker/dredge combos can save you money, offer flexibility, but are also a bit of a compromise since the dredge portion is generally small. Combo units will be equipped with a suction nozzle type of intake. This design is best for working small shallow streams and tributaries. These systems are designed to be set up alongside the stream edge and have adjustable legs rather than float systems that you’d normally see on a larger suction dredge. With a suction nozzle and more hoses, the combo unit will operate as a suction dredge, picking up material from underwater crevices and delivering it to the sluice. Highbanker/dredge combos also can be ideal for working in and around ponds in old hydraulic mining pits.
The next time you are out in the field, consider if a highbanker or power sluice can help you get more gold. To determine if the answer is yes, ask yourself these questions: Where is the nearest water? Can I shovel directly from the diggings into the feed hopper? Can I set it up to allow gravity to do a lot of the tailings clearing work? Where will the pump go? With a little thought and planning, you’ll be able to decide if highbanking for gold will increase your productivity. In most cases it will. Move more dirt, get more gold! Good luck!

Places where gold naturally concentrates in an environment of streams and drainages are known as paystreaks. No matter if you are panning, sluicing, dry washing, or metal detecting, in many ways your success at gold prospecting comes down to locating these elusive natural pay streak concentrations. Keep in mind that most gold paystreak formations occur during times of flooding and that many factors affect how gold gets deposited. Perhaps the biggest factor is that gold is dense and is more than 19 times heavier than water. The denser an object, the more easily it will resist the flow of moving water. That means it takes a very strong and fast moving water flow to move along a nugget the size of a pea.
When deciding where to start sampling, it’s helpful if you think of a river or stream as a sluice box. Waterways obviously don’t have aluminum riffles and matting, however, they do have natural gold traps that do the same thing that a sluice will do— allow gold to settle out of gravels and be caught while the bulk of the sands continue downstream. Heavy material such as gold doesn’t get spread along evenly, it is most likely caught in certain areas. The downstream parts of inside bends in a stream are favorable places to look for pay streaks. Just how good depends on how sharp the bend in the stream actually is. Usually the sharper the bend, the better the pay streak. If a tributary is known to have coarse gold, look at the intersection of the tributary and the main channel.
Behind an obstruction (large boulder, an island, or an outcrop of bedrock) is another good place to look for a pay streak. Boulders and other obstructions can create turbulence where ordinarily smooth flowing water turns into fast flowing whitewater. It is between the fast white water and the quiet dark water that gold drops out. The coarsest gold tends to be found on the outer parts of the pay streak, and the finer-sized gold is on the inner part of the pay streak. When you are working, if it seems as if the streak is petering out as you go toward the middle of the water flow because you are finding little gold, this region of the pay streak is often where the biggest number of nuggets are most likely to occur.
Once you know where paystreaks form, you might wonder if they are more likely found on bedrock or in gravels. They are nearly always found on bedrock or some sort of false bedrock. False bedrock might include caliche, a clay layer, or just a well-packed hard pan. You may just get lucky and hit something great with your first shovel of dirt, but more likely you’ll need to test a few different places. Even very experienced prospectors need to keep testing to find those hotspots and paystreaks. Good luck and keep sampling!

A good rule of thumb that most prospectors agree on is to look for placer gold on bedrock and within crevices in the bedrock. This simple principle makes sense— placer gold is heavy and dense and therefore settles at the lowest point as it is pushed around by flowing water. However, gold isn’t always going to make it all the way down to true solid bedrock at the bottom of all gravels. Instead, in certain conditions, it will be found ABOVE bedrock. When these conditions exist, gold will collect on “false bedrock.” For example, a clay layer in streams can act like bedrock and yield more gold than the true bedrock below it.
Another situation where gold cannot make it to bedrock is where the streams and gullies have “caliche.” Caliche is a form of cemented gravel often found in desert areas. The gravel is deposited by water flows, just as it would be in any other stream. The difference is that the water contains dissolved calcium salts, and as the water dries up in the streambed, the calcium salts turn into calcium carbonate or calcite. This material gets deposited on the gravel a little at a time and eventually the calcite glues it all together into a solid mass. The solid mass then acts like false bedrock and any new gold flowing across it is stopped in its downward movement by the caliche.

Historically, California has been known as the land of the big nuggets. After the Gold Rush began in 1849, some of the biggest nuggets were discovered there because so many more people were out looking. For example, in 1854, miners working underground in the Morgan Mine at Carson Hill in Calaveras County pulled out a 195-pound mass of gold. It was 15 inches wide and four inches thick! In 1859, a gigantic nugget was taken from ancient Tertiary river gravels on the slopes of Sawmill Peak near the West Branch of the Feather River and the small community of Dogtown. That nugget weighed 54 troy pounds. The spot where it was discovered was a hydraulic mine on the Willard claim that had a history of producing large nuggets in the past, including a 96-ounce nugget.
Plenty of stories abound from California, but plenty of big gold has come from other states as well. Colorado's biggest nugget weighed in at 156 ounces (13 troy pounds). It came from the Gold Flake mine located on Farmcomb Hill in Summit County, Colorado in 1877. It's easy to see why Montana's nickname is the "Treasure State" since it has produced a few big nuggets, too. One weighed 53 ounces and was displayed at the Paris World Expoition of 1889. The largest in Montana was over 170 ounces and was dug at a depth of 12 feet in Snow Shoe Gulch on the Little Blackfoot River. Nevada's largest nugget was taken from the diggings of the Osceola District in 1878. It weighed 24 pounds (but eight pounds of that was quartz). The old Spanish miners found plenty of big gold in New Mexico, including one nugget in the late 1890s that weighed over 65 ounces.
Unlike many Western states, the largest nugget in Alaska was found rather recently. In 1998, the Alaska Centennial Nugget, weighing 294 ounces, was mined along Swift Creek near the town of Ruby. This area is well known for its past production of large nuggets. A big nugget was also found in Anvil Creek near Nome which weighed 182 ounces.
North Carolina's claim to fame is the Reed Gold Mine located in Cabarrus County. It was the site of the first documented discovery of gold in 1799. For years, that 17 pound nugget was used as a doorstop because no one recognized what it was! At the time, it was worth roughly $4,000 (when the price of gold was $20.67 for an ounce). The Reed Mine actually produced a lot of big gold, including some weighing 28 pounds, 17 pounds, 16 pounds, and 13 pounds. Two different nuggets came from this area that weighed eight pounds each and another two nuggets were nine pounds each. Several more nuggets have been unearthed that weighed five pounds and less.
These examples of where large nuggets have been found are by no means exhaustive. A Google search will provide lots of fun stories about past and present finds across the United States. But no matter who has found what, the big question remains: Where do you hunt for big gold these days? Generally, big nuggets occur in places where rich gold-bearing fluids flow through the same pathways for a long period of time, allowing continued deposition of gold that lead to the formation of large pieces. These bigger pieces form where a change in geology allows a gold-bearing waterway to efficiently drop gold all in the same place. The same type of geology that produces rich pockets of ore with lots of visible gold are often the same areas where big nuggets are found. The really big nuggets are parts of pockets that have so much gold that they hold together as a single piece even after tumbling around in a stream.
The simple answer to where to hunt for big nuggets is to hunt where they have been found in the past. Past finds of big gold indicates these locations have the right geology for their formation. Big nuggets in a stream environment will work their way to bedrock very fast and stay put. They will often be lodged in deep crevices. Keep in mind that big nuggets are also worth more than their actual metal value. The fact they are so rare adds to their value. If you haven't found your big gold yet, keep looking! And if you can't wait to own your own shiny stuff, buy gold nuggets here.

For those of us with a strong dose of gold fever, the price of gold doesn't make much difference. Most prospectors seem to get much more pleasure from the process of finding the gold rather than selling it. It's the thrill of the hunt! Plus, gold remains a sound investment over time as a hedge against inflation and instability.
You might recall when gold peaked in August 2011 at $1890 per ounce. That was a very exciting time in the news— media hype always follows whenever gold takes a strong rise or dips. Over the last few years, the price has come down and is averaging around $1200 per ounce. But you might be wondering where the price is going from here. If you take a look at the chart of gold prices, it can be an indicator of what's to come.
The key to the chart is recognizing resistance levels and support levels (high and low points). When a price bottoms out, it establishes a new floor. When it breaks below that floor it is considered "bearish" and likely to drop further since it broke a supporting base price. When it breaks above a resistance level, it indicates there is strong demand which could push the price to higher levels.
Between 1978-1980, gold prices went from $172 to $830 per troy ounce. In 1982, gold prices dropped back to $328 an ounce. It was not until 1999 that the price hit the low of $253 after the peak in 1980. Never having broken that price floor, it entered a recovery where it eventually broke above the high set in 1980, pushing to $944 an ounce by February 2008. Later that same year, in October, the price hit just under $830 before skyrocketing to that crazy high of $1890 per ounce! Since then, the price has dropped from its high just as it did in the early 1980s. Gold dropped to a new floor of $1066 at the end of 2015, before bouncing back to its current levels. Since the new floor was established, it has not been broken. Instead, the price climbed to $1340 per oz. by August 2016, dropped but stayed $100 above the prior low to $1163 and has since bounced back to around $1200. If the price continues to set new highs, even if it drops thereafter and continues to set higher lows on its way up, it is considered "bullish" or positive.
Why is the price of gold so important? Maybe it's not to the average prospector, but the price of gold has a direct impact on the level of involvement in prospecting. The next sharp rise in price might bring with it additional involvement from more people. The treasure seeker in all of us might just kick in, bringing more families out to the gold fields. Good luck!

Fun and exercise are two great reasons to go gold prospecting, but you might as well make some money while you're at it, right? The best way to do that is to increase production rates. Assuming you are mining on a known gold-bearing claim or waterway, volume is the key to your success!
Graduating from the basic gold pan to some other form of simple equipment is the best way to increase production rates. Just going from a pan to a sluice will increase production by at least 500%, depending on how it is used. A highbanker will work about the same amount of material as a well-run sluice, though it can move the water to you instead of you bringing the gravel to the water, thereby dramatically increasing volume of production. A drywasher will produce similar results by allowing you to work without water.
A dredge or highbanker/suction dredge combo is the next step up. A dredge uses a gas motor to generate the suction that will load and transport the material to the sluice, which greatly increases volume, as well as allows you to reach gravel on the river bottom that would otherwise be inaccessible (unless the river is seasonal or there is a prolonged drought). The more material a dredger can push across the riffles, the more gold can be recovered. An additional benefit to dredging is that it also allows you to clean gold out of all the cracks and crevices in the bedrock. A shovel just cannot do that.
The size of the dredge intake nozzle is the most important factor in how much material a dredge can process, but it is not a direct one-to-one relationship. For example, a 5 inch dredge will not move twice the material that a 2.5 inch dredge can move. It actually can move much more. The surface of the hose is figured in square inches, the area (and therefore the volume) goes up much faster than the diameter and the corresponding production rates go up proportionally. A larger hose size will also clog less because more sizes of rock and gravel will pass through. Having to stop and remove clogs can significantly reduce the time you get to spend actually moving dirt and finding gold. No matter the size, you're likely to have rocks jam up the hose from time to time, but generally, the larger the hose the less frequent the clogs that slow or stop production. In most areas of the country, a 2 inch dredge is considered a "recreational" size and may not require a permit to use, whereas much larger nozzle sizes would require a permit. Always know the laws where you intend to gold prospect and mine before you buy equipment.
Beyond dredges or highbanker/suction dredge combos, you can get into some professional mining set-ups that use trommels and jigs and shaker tables and earth moving equipment. Every deposit is different, varying in size and grade and structure. Environmental conditions and access will dictate mining methods and knowing the rock types and size of the gravel is critical in determining which equipment will work best for increasing your production. Finding a suitable deposit to mine and finding a way to work it economically— to justify your time and expense— is the first step. Then choose the right equipment to increase your recovery rate and speed of recovery and make more money. Good luck!

Typical winter storms that regularly occur in gold-bearing areas usually do not create enough havoc to force substantial amounts of "new" gold into movement. However, when Mother Nature really goes to work over a “bad” winter, a great deal of gold can be set free, creating a bonanza for gold hunters in spring and summer. Gold veins that have been hidden for decades suddenly can be exposed. Floods can also sweep gold out of abandoned mines and wash it downriver. Known gold digs can be washed out, trees uprooted, and the landscape eroded— all pluses for prospectors!
When tons of rock, cobble, and boulders are swept downstream along bedrock during a huge storm, quite a bit of destruction occurs. Plants, weeds, and trees that normally grow along the river and gravel bars are washed away. And when a major storm or flood tears up large portions of a streambed, a fair amount of this newly-released gold, because of its weight, will be deposited along the riverbed and settle into cracks and crevices (hand dredges are an ideal tool in this situation). Flooding on this scale occurred in Colorado in 2013. After the heavy rains in the west this winter (in California, Oregon, and Washington to name just a few affected states), this summer promises to be one of the best seasons for small scale miners in many areas. Even farmers in Thailand are looking for gold now to try and make up for the economic loss of ruined pineapple crops caused by floods.
Stream bed layers caused by several floods over time are referred to as “flood layers.” Flood layers are usually a different color, consistency and hardness from the other layers of material within the streambed, making them easy to recognize. Larger, heavier pieces of gold will work their way down toward the bottom of a flood layer as they are washed downstream. The smallest and lightest flakes of gold might not work their way down through a flooding layer at all, but might remain dispersed within the material. Of course not all flood layers contain gold in large quantities, but it’s a good place to start. In early spring, rivers are still high in most places, but in the next few months, stream beds could be exposed for better gold hunting. Some of the best areas to look for flood gold are where the stream or river widens out, or levels out, or changes direction. These areas can allow concentrations of gold to collect either on bedrock or in the contact zones between layers. Another place that tends to collect gold are gravel bars, especially the ones located towards the inside of bends in a waterway.
No one ever hopes that Mother Nature releases the type of fury that causes loss of life and property, but when a catastrophic weather event occurs in a gold-bearing area, take advantage of it. Get out there and get your share of the shiny stuff! With so much more runoff than normal shaking gold from them thar hills, the best prospecting will come in the summer months when the water has receded. Good luck and be safe!

You might think that glaciers are important to gold prospecting only in Alaska and the Yukon, but glaciers have also affected placer deposits in the Midwest and some western states, too.
What is a glacier?
Glaciers are formed when a huge mass of ice is created by accumulated snow. The body of ice grows over the years when more snow falls during colder months than melts during warmer months. Glaciers shrink when the melting is greater than the snow accumulation. Once the weight of the glacier grows large enough, the weight of the snow and ice presses down and compacts. The body of ice will then slowly flow downhill. The power of the solid ice moving downhill rips loose rock and soil. Solid rock underneath the glacier that is firmly attached to the mountain will stay in place, but be polished and smoothed as the glacier slides over it. Scratch marks and gouges appear along the surface of these polished rocks and indicate the direction that the glacier was moving.
Eventually the body of the glacier reaches a warmer elevation where the ice melts more easily. Here, at the foot of the glacier, are gigantic piles of rocks and boulders and debris that have been bulldozed down by the moving massive glacier. These glacial gravels are known as “moraines.” However, finding gold in this unsorted jumble of glacial moraine material produced by a glacier’s bulldozing effect is like finding a needle in a haystack—not worth the time to process…. until the glacier’s natural melt waters or another water source washes through it, and does a bit of natural sorting.
Alluvial gold deposits
Normal alluvial placer deposits form by the power of flowing water washing away lighter materials and gravels and leaving behind heavier material such as gold— very similar to what happens in a sluice box when the flow of water washes away the lighter materials and the gold is deposited in the riffles. When flowing streams and glacier melt water process and wash away the glacial moraine gravel, the gold works its way downward. Gold will then be deposited on bedrock or false bedrock (such as clay or other packed material). As the glaciers themselves melt, the huge quantity of water creates an effective sluicing system that can sort the gold out of gravels. These flows can leave behind very profitable pay zones along the channels cut by the ice melt waters on bedrock benches, among packed false bedrock gravels, and on the downstream side of bedrock high spots.
Where to look for glacial placer gold deposits in the West
In California, glaciers still exist in the southern Sierra Nevada, small parts of the Cascade ranges and the Shasta-Trinity Alps. In the northern Sierra Nevada and higher parts of the Klamath and Trinity ranges, that area’s placer deposits were greatly affected by glaciers that existed thousands of years ago. Glacial derived placer gold is important in a number of other western states, too, including Idaho (Boise Basin and Mount Pisgah), Montana (Pioneer District, upper portions of Gold Creek near Deer Lodge) and in Colorado (Fairplay District, Arkansas River Valley in southern Lake County).
Where to look for glacial placer gold deposits in the Midwest
What you might be very surprised to know is that glaciers are the source of nearly all the placer gold found across the Midwest. During the past ice ages (which were repeated events, not just a one-time occurrence), great sheets of glacial ice leveled the middle parts of North America, acting like giant bulldozers by pushing enormous amounts of material southward from Canada. When the ice melted, the area was left with extensive glacial moraine (gravel) deposits. Although it’s spotty and sporadic, some of these glacial deposits have gold, depending on where the glacial gravels came from in Canada and if that region was gold-bearing. Glacial gold is found in several of the northeast states such as New York, Vermont, and Pennsylvania. Glacial gold is also found more extensively in Midwest states such as Indiana, Illinois, Ohio, Michigan, Wisconsin, Iowa, Minnesota, Kansas, Nebraska, Missouri and the Dakotas.
All things considered, while glaciers can destroy a placer deposit, the moraines they leave behind can produce some very worthwhile deposits of gold, and are worth prospecting if you live in or visit these areas.

Metal detectors are electromagnetic devices and can detect items that are conductive or magnetic, or both. Gold is an example of a non-magnetic conductive item. Iron is both conductive and magnetic. Almost all major advances in prospecting metal detectors over the last 40 years revolve around improving ways to ignore and see through ground mineralization while still finding gold nuggets. If you’re using any brand of VLF (very low frequency) metal detector to prospect for gold, choosing the correct operating mode (also called search mode) can make or break your success.
Experts recommend that any metal detector you are considering for gold prospecting should have a true all metal mode. This mode is important because of its lack of filtering applied to the signal. It will normally offer the best depth and the best sensitivity to small gold. Unfortunately, two common problems occur when using All Metal Mode: interference from ferrous iron and steel junk, and from hot rocks. A hot rock is nothing more than a rock that has a different magnetic content than the ground. Some rocks are that way because they contain conductive minerals besides gold. The Discrimination knob on your detector will help with these two problems.
Discrimination is a type of electronic filtering. The signal is analyzed, and depending on the discrimination setting, identified as either a target to be dug or a target to be ignored. Applying more discrimination eliminates more trash, but be careful—you don’t want to completely eliminate all ferrous trash because an aggressive level of discrimination easily tunes out gold. So be prepared to still dig ferrous junk which usually turns out to be larger chunks of steel and iron. Also know that discrimination circuits can be fooled, especially in ground with lots of iron mineralization. This ground condition can override the small gold signal and cause a faint gold signal to be identified as ferrous. Even with this limitation, the discrimination mode can be invaluable for finding gold in extremely trashy areas. Trashy areas are where a VLF detector can really outshine a PI (pulse induction) machine, especially when dealing with nails, bits of rusted cans, and other small trash. If you’re in the market for a metal detector, some manufacturers offer special holiday packages such as the 3 listed below.

Researching and exploring new areas in which to prospect for gold, gems, or whatever you are seeking can be a lot of work, but the process can go much quicker and easier when you know where to start. If the weather where you live is keeping you indoors much of the time this winter, use your downtime wisely by researching and planning for next spring and summer. But don’t rely on just one source of information. Confirm it through several sources. It’s not that you don’t trust Uncle Joe or a “friend of a friend” tip, but facts can be distorted or forgotten over time and that “secret” nugget patch found 30 years ago just might not turn out to be quite so secret any more.
The best kind of research brings together different forms of info from a multitude of sources. It is the info gleaned from COMBINED sources that can help you to determine the best possible place to locate precious metal or gems. The more info you can lay your hands on, the better. Consider these resources:
Old mining district reports and mining history books. Most western states have some form of mining and geology agency, although they all have different names depending on the state. Find out what information is publicly available at the agencies located in the area you will want to prospect. Old history books can be more help than any state agency because they were written by folks with ties to the area they wrote about. That means they often include valuable information on old mining discoveries or operations that didn’t make it into a government report.
Topographic maps. Many old mining areas are shown on topo maps, but usually not on the newer versions, so try and find older topo maps. Many of the newer versions may have old mines removed as a way for the government to “keep the general public safe” by not advertising the whereabouts of the old and “dangerous” mine shafts.
Aerial photos. Google Earth is amazing in its quality and detail of photos. Many times you can see individual trees, hiking trails, rock outcrops and even hand-stacked piles of rocks left behind by old-timers. Sometimes larger features and patterns (areas where miners removed a lot of brush, for example) cannot be seen from ground level, but are obvious from far up in the sky. This is also a good way to get an idea of the condition of the roads in the area so you’ll know in advance which look to be commonly traveled. Google Earth ties in with GPS, too. You can review the photos, check them against maps, and get the GPS coordinates of the precise location you want to visit. No more guessing if you have arrived! You will know for sure with GPS that you are in the right spot.
Reference libraries. The librarians at state mining divisions and university libraries are generally very friendly and helpful. These libraries are open to the public, so don’t feel shy about requesting help. Any university with a good-sized geology or mining program should have quite a few geologic reference resources including old reports, magazines on the mining industry, thesis reports by graduate students, and even reports by engineers and geologists who were on site at the big operating gold mines in the late 1800s. Many of the old books and reports found in the university libraries will be out of print and cannot be purchased anywhere, so be sure to make photocopies of any documents you need while you are onsite.
Many prospectors are discouraged by the amount of work and time that can be involved in researching new areas, but when you find a new spot with good gold, it will be well worth your time and effort!

Teknetics T2 is a multi-purpose high-performance computerized metal detector. When this detector was first released the price tag was $849 -- now it's only $499! It has the high sensitivity and ground cancellation features needed for professional gold prospecting, the discrimination responsiveness needed for serious relic hunting under difficult conditions, and visual Target-ID considered essential in searching for coins. The ground cancellation system can be adjusted to allow searching saltwater beaches.
This detector comes with an 11-inch elliptical Bi-Axial searchcoil for maximum detection depth in mineralized soils. An accessory bundle for the T2 includes a smaller coil, backpack, hat, and more is also available (additional charge). This machine is light weight and the best balanced of any high-performance metal detector, so you can hold and swing it almost effortlessly. The armrest position is adjustable to fit your arm. The grip is durable high-friction foam elastomer, comfortable in any kind of weather. The controls are conveniently located and easy to learn how to use. Locking collars on the tubes eliminate rattling. The entire menu is always visible on the LCD display. The LCD display indicates the electrical signature (Target-ID) of the detected metal object. The display provides continuous information on battery condition and on ground mineralization, which affects detection depth. Help messages are automatically displayed on the lower right corner of the display when necessary.
A great benefit of the Teknetics T2 is that it is easier to learn to use properly than other comparable metal detectors. A few of its best features inclue:
The T2 is powered by four AA alkaline batteries, which will typically last for more than 40 hours of use before needing replacement. The lead engineers on the design team were John Gardiner, firmware engineer, and David Johnson, whose expertise is behind many of the best-known high-performance metal detectors offered by major U.S. manufacturers for the last 26 years. 5 year manufacturer warranty from First Texas Products, LLC.
Most metal detectors, like the Teknetics T2, use VLF Induction Balance technology. Here’s how it works: The searchcoil (also called search head or loop) contains two electrical induction coils which are like antennas. One coil transmits a rapidly alternating magnetic field, illuminating the region surrounding the searchcoil. If metal is present, its electrical conductivity distorts the magnetic field. If iron metal is present, its magnetism also distorts the magnetic field, but in a different way, allowing the metal detector to distinguish between ferrous and nonferrous metals. The other coil is a receiving antenna which detects changes in the magnetic field caused by the presence of metal. Electronic circuits amplify this weak signal, analyze it to determine the changes which occur as the searchcoil sweeps over the target, and then convey the information to the user in the form of a visual display or audio tones. Most modern metal detectors perform many of these tasks in software running on an internal microcomputer. The iron minerals which are present in most soils also distort the magnetic field, obscuring the weak signals of small or deep objects. This can cause the object to go undetected, or to be misidentified when it is detected. Much of the technology that goes into modern metal detectors is devoted to the task of eliminating the unwanted signals from iron minerals in the soil, while not losing the signals from metal objects.

As you read this, water levels in many Western states will be at their lowest of the year— in some cases, the lowest in a couple of years. Snow levels in many of the mountain ranges were only a fraction of normal for the second or third winter in a row. Drought conditions continue in the majority of California, Nevada, and many parts of Oregon, Arizona and New Mexico. About now, water temperatures are also at their warmest in many places. What does this mean for gold prospectors? OPPORTUNITY! Low water levels in rivers and streams offer the best time to snipe for gold, so take advantage of this unique way to gold mine this summer.
Gold sniping, also called crevicing or cracking, is basically cleaning out cracks and crevices in and around bedrock— areas that were submerged for many, many years but are accessible during times of drought. These areas have the potential to trap and retain gold. After visually determining the best places to snipe (more on that later), all you need are a few simple tools for collecting and panning the high-grade material from those cracks. Basic, yet effective!
When normally rushing rivers and streams are reduced to a trickle and boulders and bedrock are exposed, you won’t need a wet suit or snorkel, only some waders. The boulders can still be very slippery, though, so keep that in mind when crossing waterways. Most snipers do use a mask and snorkel and wetsuit. In addition, the basic tools for sniping include a plastic gold pan, long stainless steel tweezers, snuffer bottle, plastic vials, pry bars to loosen jammed-together rocks, a garden trowel or similar tool to dig behind boulders, and a bucket. A hand dredge or nugget sucker can really come in handy, too.
The first step in prospecting, of course, is to stop by the appropriate BLM or Forest Service office to determine where you can recreationally hunt for gold. You don’t want to accidentally trespass on someone else’s claim. Once you’re there, visually study the river and think about all the areas that gold might be hiding. Loose flakes or nuggets of placer gold are much heavier than the surrounding sand and gravel, therefore, the dense metal gradually works its way downward and collects in seams in the bedrock. The inside bends of rivers tend to be good collection spots because the water slows there, allowing the heavier sands and metals to collect in and around anything that obstructs its path. Try investigating the exposed underwater root systems of any trees found along the bank, too. These act as natural gold traps. Large boulders offer opportunities as well. It's best to snipe on the downstream side of these monoliths since the back eddies occurring there sometimes pull gold and other heavy materials out of the passing current and force them to settle.
If you’re sniping underwater, float on the water with your mask and snorkel, going downstream with the current. Look for crevices below the waterline that are reachable. When you locate a likely spot, remove the loose sand that commonly fills crevices in the bedrock. “Fan” away the sand and lighter debris with your hand, then use a pry bar or other crevice tool to loosen packed gravels. Once exposed under water, gold just seems to glow, especially on a sunny day, so it’s easy to use tweezers to collect the flakes and pickers. Walnut-sized nuggets are few and far between, but the thrill of the hunt will keep most snipers looking! Be sure to thoroughly clean out each crevice because the majority of the gold is going to be concentrated at the very bottom.
When you need a break from getting your feet wet (or the rest of you), panning along the bank or using a gold vacuum in the dry material along the shoreline can be lucrative. When the water level is low, plants, logs, and smaller rocks that used to be below the waterline are now visible. Gold might have collected around these obstructions when they were under water, but no one thinks to look here because they’re now in plain sight and almost too obvious. What others miss could be your bonanza!
Bigger is not always better. With most mining operations, the more dirt you move, the more gold you get. Sniping is about the little things— working smaller areas very thoroughly. Perhaps the most pleasurable thing about sniping is its simplicity. You can hike in and get away from the crowds, and enjoy some peace and quiet and lovely scenery. It is a cool way to spend a hot summer day, and if you have patience and really learn to read the stream, you will find more and more gold using this method. If you’re new to gold sniping, you also might want to search YouTube for videos showing snipers in action.
As difficult as drought conditions are for farmers, ranchers, and many others, prospectors can use the low water levels to our advantage. Now is the time to work potential bedrock hot spots that could never be reached in normal years. Summer won’t last long, so get out there and get your share of the gold… sniping is just one more mining method that could have you yelling “Eureka!”

In the spring of 1859, flakes of gold were found in Clear Creek, a tributary of the South Platte River in north central Colorado. Some prospectors were happy finding rich gold dust, but John Gregory was determined to find the source. For months, the Georgia native followed North Clear Creek upstream from the present-day city of Golden, and on May 6, 1859, made the first lode discovery in the Rockies! Gregory sold his two claims for $21,000 a few months later and left the area, but his name carries on. “Gregory Gulch” is located between the towns of Central City and Black Hawk. The Gregory Mining District encompasses these towns plus several other mining camps, and as a whole, this area is referred to as "The Richest Square Mile On Earth.” Central City takes it name from being “central” to all the mining activity.
Within two months of Gregory’s initial gold discovery, 900 fortune-seekers were living in log shanties and tents. By the following summer, the population had swollen to 10,000. In no time, businesses and mills were thriving and the area became the leading mining center in the Kansas Territory. At this time, Colorado wasn’t yet a state, but its prominent place in mining history was already secured. Between 1859 and 1918 (considered by the National Register of Historical Places to be the area’s “period of significance”), the total gold output was $83,364,157! Most of this was in the form of placer gold, which was extracted with pans and sluices. This “easy” gold played out within the first five years of discovery, and by the end of 1863, most work had shifted to hard rock mining.
The promise of riches continues to lure people to Central City today, but it’s not so much to find gold— but to gamble. Limited stakes gaming was legalized in 1991, and has made this area an important destination once again. Gambling was big business here in the 1880s, drawing the likes of Doc Holliday, and even Soapy Smith all the way from Alaska. The downtown core is now a National Historic District, and casinos reside in many of the restored historic buildings. Much of the beautiful and original woodwork, ceilings, and ornate furnishings date back to the 1870s. A scenic loop drive in the hills above the town is the place to find gold rush cemeteries, abandoned mines, headframes, and many other mining relics.
Take a Walk
The best way to learn more about Central City’s gold rush and admire its architecture at the same time is to stop at the Visitor Center on Eureka Street for a walking tour map. Choose from several self-guided walking tours, depending on your interests. Many of the town’s most magnificent buildings are in downtown, whereas Victorian residences are located outside of the business district. No matter how much ground you want to cover on foot, keep in mind you’re above 8,000 feet in elevation here, so pace yourself. Some buildings are open for guided tours (admission charged) but even if you don’t peek inside, you’ll get a good sense of the town’s history right from the street. If you want to shake hands with one-armed bandits or play poker at any time during your walk, you’ll find a chance to meet Lady Luck every step of the way.
One of the most notable buildings in downtown is the 150-room Teller House Hotel. Located on the corner of Eureka and Pine Streets, it was built in 1872 at a cost of $87,000, plus another $20,000 to furnish. From its non-descript exterior, you’d never believe that the Teller House was once considered to be the most elegant hotel between Chicago and San Francisco. Financed largely by Henry Teller, who became the first senator from Colorado and later, Secretary of the Interior, it’s no longer used as a hotel but is the center for opera-related activities (Central City Opera House is next door).
In April of 1873, President Ulysses S. Grant came to see his friend Henry Teller. To impress the president, mine owners decided to lay 26 ingots of solid silver to make a path to the entrance to the Teller House so President Grant wouldn’t have to dirty his boots when he stepped from his carriage. Those wealthy citizens also had an ulterior political motive. At the time, Congress was debating whether gold or silver should back the dollar. Legend has it that Grant became angry when he saw the silver bars and walked up the boardwalk instead of on the silver path so as not to show favoritism. As we know, gold eventually won.
The grand opening of the Opera House in 1878 (next door to the Teller House Hotel) started a tradition of community theatre, ranging from opera to vaudeville. Buffalo Bill Cody performed here as well as P. T. Barnum’s circus. The Opera House is known for its elaborately frescoed ceiling and perfect acoustics. In addition to Central City’s very popular Opera Festival held each summer, performances are held year round in this beautifully restored 550-seat theatre. The Opera Association also owns the Williams Stables building on Eureka Street. Initially constructed in 1876 for the use of Teller House guests, the building was purchased a few years later by Sheriff Dick Williams and his son. It was from here that a Stanley Steamer automobile could be had for hire— quite an achievement back in the day!
Many of the Main Street establishments are identified by “blocks” and named for their original builders. In addition to the Teller House Hotel, Henry Teller also built the Teller Block for $6,000 in 1874. The upper floor was purchased a few years later by the Independent Order of Odd Fellows, which retained ownership until the 1990s. The Mullen Block was completed in 1874 by Thomas Mullen. Originally a drug store and clothing store, the Elks Lodge bought the building in 1902. The Harris Block was built in 1875 by Robert Harris and was home to the New York Store Mercantile that sold dry goods, clothing, and furnishings.
Gold in Them Thar Hills
The scenic forested hills above town offer evidence of the thousands of mining claims that placed Central City and the surrounding area in the history books. When you’re ready to take a short loop drive, the helpful staff at the Visitor Center will point you in the right direction. The route is mostly a well-maintained dirt road that takes you past headframes, abandoned mines, and sites of once thriving communities. Nevadaville is one such mining camp that 1,200 gold seekers used to call home. Along the route you’ll see the Coeur d’Alene Mine. Originally opened by Robert Cameron in 1894, the shaft reaches some 700 feet into the depths of Gunnell Hill. Records indicated that in 1915 this mine employed nine men who earned from $3-$4 per day. You’ll also see the shaft house of the Boodle Mill. Because of the serious safety hazard posed by abandoned mines, trespassing laws are strictly enforced. Although tempting to explore, keep away from old mines and tailings to avoid accidents.
Known for their excellent stonework, the rock retaining walls visible in various places along the route were built by a very large population of Cornish miners. The walls were part of the former Gilpin Tramway, a 26-mile narrow gauge railroad that once looped around the gulches and through the surrounding communities. Sidings went to many of the major mines. Most of the retaining walls don’t use mortar, and were instead constructed using a dry-stack method. After more than a century, most of the rockwork is still holding up— no maintenance required.
The loop drive also takes you through the “cemetery district.” Many stories are told through the memorials and headstones. Harsh weather, less-than-clean water, mining accidents, and few physicians were the norm during the gold rush. So were epidemics of scarlet fever, diphtheria, and the Spanish flu. Sadly, you’ll notice that a large number of children are interred within the cemetery fences. When you visit, please remember these sites are historical grounds, but are also still in use today. The Gilpin County Historical Society also holds an annual “Cemetery Crawl.”
"Oh My Gawd Road"
After getting your fill of gold rush history and gambling, a popular route leading out of Central City to Idaho Springs takes about 30 minutes. It isn’t quite as bad as its moniker, but it’s not for the faint of heart either. The “Oh My Gawd” Road (CR 279) is more dirt than pavement and wouldn’t be wise for drivers who don’t like narrow, twisty roads, but the mountain views make it worth it. Along the bumpy route you’ll pass the famous “Glory Hole” mine workings, drive through Russell Gulch, and see many more mining relics that attest to “The Richest Square Mile on Earth” in days gone by.
IF YOU GO:
Central City is located in the Rocky Mountains, only 35 miles west of Denver. With the newly opened, Central City Parkway, visitors can reach Central City 12 minutes after exiting off of I-70 at exit 243.
The Central City Visitors Center is located at 103 Eureka Street, at the northern end of Main Street in the old Wells Fargo Building.

Victor, Colorado -- the City of Mines
Victor is a small quaint mountain town now, but back in the late 1890s, more than 8,000 lived and worked here. By the time the town was platted in 1893, it was already known as the City of Mines because the largest and richest gold mines of the Cripple Creek and Victor District were located on Battle Mountain just above town. Today, several headframes still jut into the sky, and brick buildings dating to 1899 still line the streets. Between 1899 and 1902, booming Victor boasted 48 saloons, 29 doctors, 15 restaurants, 12 banks, eight pharmacies, six churches, five architects, two newspapers and more. In early 1899, a fire destroyed the original false-front pine buildings and left 3,000 people homeless. Within six months, though, the businesses were rebuilt in brick or stone. Just like in Cripple Creek, Victor saw its share of the Colorado Labor Wars, too. The Western Federation of Miners union hall on 4th Street has some telltale bullet holes to prove it!
Interpretive signs posted at intersections around Victor relate colorful stories about the Red Light Social Clubs, the famous girls who entertained at the Fortune Club, and about the town’s founders. Take a walk and envision the streets as they would have been over 100 years ago. If you need a little help imagining yesteryear, the photographs in the Lowell Thomas Museum depict life in early Victor, and it is also the best place to learn about the town’s pioneers. The museum’s namesake is none other than the internationally renowned radio news broadcaster, author, and film producer Lowell Thomas. Between 1930 and 1976, Mr. Thomas’s 15-minute nightly news and commentary aired just before the famous Amos ‘n Andy Show, and had a audience numbering more than that of the NBC, CBS and ABC TV news anchors combined. Victor was Lowell Thomas’s boyhood home.
American Eagles Scenic Overlook
A few miles outside of Victor, you’ll find an impressive view of the Cripple Creek and Victor Mining District from atop the American Eagles Scenic Overlook. Stop at the Victor visitor center first (formerly a train depot) for a map. From an elevation of 10,570 feet, you get a bird’s eye look down into the CC&V surface operations where massive 240-ton haul trucks riding on 12-foot diameter tires haul ore up and down a abyrinth of roads. Mount Pisgah and the Sangre de Cristo and Collegiate Mountains make a nice backdrop.
In 1895, the American Eagles Mine at this site was the highest underground mine in the district. This mine had three shafts, the deepest had reached 1,540 feet by 1902. Shafts are vertical excavations through which miners and supplies are taken into and out of underground workings. Headframes sit above the vertical shaft in order to support the sheave wheel or pulley system that passed the hoist cable from the steam or electric-powered hoisting mechanism to the metal cage that hauled men and supplies. Tunnels on the other hand, are horizontal excavations, driven from the surface into the side of a hill to connect with the underground workings some distance away. Technically speaking, tunnels have surface openings on both ends. A one-opening tunnel is an adit.
The original American Eagles headframe is still standing proudly, and the double-drum hoist is still in its place, too. The shaft, however, has been sealed. Remnants of a blacksmith shop and mine superintendent’s house are also at the overlook. Interpretive signs around the site tell the story of Winfield Stratton who purchased the American Eagles in 1895 after a huge success with his local Independence Mine. In fact, Mr. Stratton was Victor’s first millionaire and sold the Independence Mine for $11 million. The American Eagles was worked until 1940, but unfortunately little is known about its actual production since it was a private claim.
On your drive up to the American Eagles Scenic Overlook, expect to stop at a checkpoint and give your name to a Cripple Creek and Victor Gold Mining Company employee. Your visit is welcomed, so the checkpoint is for nothing other than your safety. You’ll be told if it is OK to proceed (the road is closed during blasting), and will be cautioned about the giant haul trucks that share part of the same road. Access the American Eagles Scenic Overlook north of Victor at the intersection of County Roads 81 and 83 on Bull Hill Pass. The route is signed.
Trails of Gold
The remains of many mining operations pepper the landscape in and around Victor. Quite a few sites are connected by hiking trails (pick up a map at the visitor center in Victor). These “Trails of Gold” offer up-close looks at more relics of yesteryear as well as active mining activities. The trails include good signage about the area history. Some buildings are heaps of rubble, some are still standing— it all depends on Mother Nature. Be careful when exploring these sites, and if you’re normally a flatlander, remember that you’re trekking at elevations of 9,500-10,500 feet above sea level.
The Independence Town Site is an interesting stop. The steel headframe of the Vindicator Mine is hard to miss, and a gravel path takes you past what’s left of a surface plant, ore processing facility, and a residence that has definitely seen better days. Independence originated as Hull’s Camp on the Hull City placer claim. Although some placer gold was found, the real riches came from underground veins, so there were several different mines here. The Vindicator is credited with producing a total of 1,244,000 troy ounces of gold between 1895 and 1953. Also nearby is what remains of the Theresa Mine, which produced over 120,000 troy ounces between 1895 and 1961.
Cripple Creek and Victor continue to pay tribute to their 1890s heritage as The World’s Greatest Gold Camp. In and around these tiny towns, much of the area’s gold rush history has been preserved and continues to be a source of pride for the Centennial State (the nickname comes from Colorado becoming the 38th state, 100 years after the signing of the Declaration of Independence). Whether you want to tour gold mines, participate in year-round special events, visit museums, or just marvel at the historic headframes and other vestiges of mining equipment backdropped by mountain views, there’s a wealth of activities and sites to keep you interested and entertained.

The Town of Cripple Creek, Colorado
The gold rush not only brought prospectors into the quiet ranch town of Cripple Creek, but it brought in goods and services needed by those miners. Lumber yards, hotels, 100 saloons, 91 lawyers, 80 doctors, 40 assay offices, 14 newspapers, three railroads, two electric streetcar systems, and a trolley turned a small town into a booming gold camp of over 50,000. Interestingly enough, Cripple Creek was also the site of some of the worst mining labor conflicts in American history, culminating in the state militia being called in in 1903. Several celebrities also spent time here, including comedian and film star Groucho Marx, lawman and gambler Wyatt Earp, and boxer Jack Dempsey. Unfortunately, two accidental fires burned much of the city in 1896. Wisely, however, the city fathers declared that the business district be rebuilt in brick, and so many of those rebuilt buildings are still standing.
In addition to its golden history, the restored town of Cripple Creek is now known for its casinos. Limited stakes gambling was approved by Colorado voters in 1990, so visitors can try to strike it rich 24 hours a day. If cards or craps or one-armed bandits don’t hold any appeal, skip the dozen or so casinos in town and instead enjoy the town’s many other attractions.
A four-mile narrated ride on the Cripple Creek & Victor Narrow Gauge Railroad passes several historical sites that can only be seen from the rails. The train is pulled by a coal-fired steam locomotive that looks a bit like Thomas the Tank Engine thanks to the baby blue paint. You can also see what it would have been like to be part of the criminal element in the early 1900s by visiting the Cripple Creek Jail Museum. It is housed in the red brick building that served as the Teller County jail from 1902 until the 1990s. The original cells are there, along with displays that highlight the laws and lawlessness of the 1890s.
The Cripple Creek District Museum is housed in five original historic buildings— all filled with antiques and mining equipment. The Cripple Creek Heritage Center is a great place to learn about the entire Pikes Peak region. Looking for a highlight found in low lighting conditions? The Mollie Kathleen Gold Mine is located just outside of town, and is America’s only vertical shaft mine tour. After descending 100 stories, ride an air-powered mine train and learn how hard rock miners followed veins of gold. This historic mine was founded in 1891 and is named for its owner, Mollie Kathleen Gortner, the first woman in history to register a mining claim in her own name.
Cripple Creek and Victor Gold Mining Company (CC&V)
As you drive through the mining district today, you will see signs of active mining in just about every phase. The Cripple Creek and Victor Gold Mining Company (CC&V) operates a low-grade, surface gold mine, the largest in Colorado, between Cripple Creek and Victor. CC&V is doing extremely well and has poured in excess of 4 million ounces of gold from its Cresson Mine. CC&V, which has operated in the district for nearly 40 years, began its Cresson Project in 1995. The Cresson is named for the historic underground mining operation that was responsible for the famous great gold find of 1914— the “Cresson Vug.” A vug is a cavity in the rock, lined with crystals somewhat like a geode. The Cresson Vug produced 60,000 troy ounces of gold that was essentially picked from the walls of a room-sized void 1,200 feet below the surface. What a bonanza!
If you’d like to see a working gold mining operation, CC&V hosts seasonal tours. Don’t miss this exciting opportunity to see giant haul trucks, shovels, and drill rigs in action. Watch boulders being crushed into gravel and learn about the safe, environmentally responsible mining and refining methods. Once you’ve seen a modern-day mining operation for yourself, you’ll gain another level of appreciation for the old-timers who didn’t have it so easy! And after learning about reclamation standards, you can set the record straight with those who argue that mining does nothing but permanently destroy the earth. Under current permits, CC&V plans to continue recovering gold here until at least 2026. If underground mining is resumed (exploratory results look good), work could be extended another dozen or so years beyond that. With an average pay and benefits package worth $80,000, several thousand CC&V employees are enjoying good paying jobs!
On Highway 67 between the towns of Cripple Creek and Victor, you will cross the highest bridge on the Colorado State Highway system. The bridge across Arequa Gulch was built in 2000-2001 for $418 million by the CC&V to accommodate their expansion. The 1,218 foot long bridge is over 250 feet tall at its highest point. The road is currently being rerouted again due to more growth. Near the bridge is CC&V’s leach facility and gold ore processing plant. The Valley Leach Facility (VLF) is where the gold is recovered from the ore by leaching with a sodium cyanide process solution. You can’t miss what looks like giant rock piles. The VLF actually functions like a big bathtub filled with crushed ore. The solution is applied to the ore using a drip irrigation system. The sodium cyanide process solution dissolves the gold and silver on the surface of the rock. The “bathtub” has a triple thick liner and a state-of-the-art monitoring and detection system to ensure zero discharge. The gold-bearing solution (called "pregnant solution”) is captured at the bottom of the liners. Gold is then recovered from the pregnant solution with a carbon absorption process. North of the VLF is the crushing facility that can process approximately 50 tons of ore per minute. Trucks load up the pulverized ore and delivery it to the VLF. This process recovers a whopping 200,000 ounces of gold annually. Eureka!

Like most gold regions that boomed in the 1800s, Colorado’s Cripple Creek Mining District came from humble beginnings. Little more than cattle roamed the high valleys perched nearly two miles above sea level, and prior to ranching, generations of Ute Indians had lived off the land. But unlike most boomtowns, the gold never completely ran out here, and it continues to be mined successfully today. Historically, the Cripple Creek Mining District has produced over 24 million troy ounces of gold, along with some silver. That amount exceeds the combined production of the California and Alaska Gold Rushes! The millions made from 1891 through the present has earned it the distinction of “The World’s Greatest Gold Camp.” Today, the district is not only filled with gold rush era buildings and mining relics, but you can also tour real mines, visit interesting museums, ride the rails of a narrow gauge train, hike and bike while admiring mountain scenery, and even gamble on Lady Luck at the casinos.
Pikes Peak Gold Rush
The Pikes Peak Gold Rush officially began in 1859, a decade after the California Gold Rush. At that time, the land was still part of the Kansas Territory. The first color was actually found a few years earlier in 1850 at the confluence of Ralston and Clear Creeks, but John Ralston was California-bound, so the shiny stuff stayed where it lay… for a while. Several prospecting parties returned to Ralston Creek in 1858 and 1859, but didn’t find much. In fact, many were so discouraged that they didn’t stick around. The dedicated prospectors who persevered referred to those who gave up as the “Go Backers.” Soon enough, though, a few productive placer deposits were found along the South Platte River at the base of the mountains, the canyon of Clear Creek in the mountains west of Golden, and South Park. Word spread of these glittering discoveries, and “Pikes Peak or Bust” became a popular mantra. During the next several years, 100,000 gold-seekers headed for Colorado; 50,000 completed the journey; half of those became “Go Backers” and the remaining 25,000 turned a territory into a state in 1876.
Cripple Creek Gold Rush
Most of the initial easy-to-reach gold deposits were largely played out by 1863, but then ranch hand Robert Womack started an even bigger gold rush. He found the shiny stuff in Cripple Creek in 1890, causing thousands of prospectors to head to the southwest slopes of Pikes Peak. Sadly, Womack died penniless several years later, even though his El Paso claim, which he sold for $500 and a bottle of liquor, produced millions of dollars in gold for the buyer. Between 1894 and 1917, over 500 mines operated in the Cripple Creek Mining District, which also included the thriving town of Victor. Headframes and other relics from many of those historic mines have been preserved, so it’s easy to get a good look up close.
Perhaps one of the reasons it took 30 years for gold to be found in Cripple Creek following the state’s first gold rush is because no one expected gold, especially not millions of ounces, to be in this area. Most of the old-timers’ theories about how to locate gold just didn’t hold up here. Modern geologists know that areas that were highly volcanic in prehistoric times, are likely places to create rich underground deposits. The six square miles that comprise the Cripple Creek & Victor Mining District are located in the caldera of an extinct volcano. From what one frustrated miner wrote in Cripple Creek Illustrated, some early prospectors were stumped by the gold in this region:
“Geographically, Cripple Creek is a freak. It is erratic, eccentric, and full of whims and caprices. That is, it is so to the man of science and the miner of experience. It is a vast crater bed in which the elements once were wont to make merry with nature and play unexpected pranks… The veins run here, there, and everywhere, cutting in all directions and even violating the theory that to have real value the vein should strike toward the poles of the earth.,, the experience has been that the deeper down into the earth the shafts penetrate, the richer is the ore, and the wider, more solid, and enduring the deposits.”

Typical winter storms that regularly occur in gold country usually do not create enough havoc to force substantial amounts of "new" gold into movement. However, when major flooding like what happened in Colorado in September of 2013 is followed by a “bad” winter, a great deal of gold can be set free. When tons of rock, cobble, and boulders are swept downstream along bedrock during a huge storm, quite a bit of destruction occurs. Plants, weeds, and trees that normally grow along the river and gravel bars are washed away. And when a major storm or flood tears up large portions of a streambed, a fair amount of this newly-released gold, because of its weight, will be deposited along the riverbed and settle into cracks and crevices.

Some say that "gold is where you find it" and while that may be true, once you arrive at a known gold-bearing location, how do you decide where to dig first? Successful prospectors follow different methods, so there is no single "right" way, but no matter if you are sluicing, dry washing, or metal detecting, if you first consider the "lay of the land" you can better pinpoint a place to start.

If you've been prospecting for gold using a pan, sluice, highbanker or other traditional piece of equipment, there's another tool you may want to consider— a metal detector. Gold detectors are not necessarily higher in cost than an all-purpose detector, but they are built with a higher sensitivity to pinpointing pieces of gold, and have better ground balancing and discrimination abilities.
If you're not familiar with metal detecting, the first thing you should know is that your detector does not actually detect metal directly. It detects magnetic fields. When switched on, your VLF (very low frequency) detector first creates a magnetic field and energizes anything in the ground that responds to a magnetic field. Next, your detector seeks to find a magnetic field that has a response to its initial magnetic field. Because metals conduct electricity, they respond to a magnetic field and generate a small magnetic field of their own. Detectors detect the secondary magnetic field that conductive targets create whey they are energized by the first magnetic field sent into the ground by your detector. In general, the larger the metallic target, the larger and longer and stronger its magnetic response will be.
PI (pulse induction) detectors work a bit differently by putting magnetic field energy into the ground and then switching off and waiting a very short period before they start to look for a response. This makes them better at handling ground mineralization than a VLF detector because during that short delay the magnetic response of iron trash minerals that you don't want to find dies out, but the signal from tiny bits of buried gold does, too. VLF detectors are more sensitive to finding the smallest bits of gold, but do not as easily cancel out ground mineralization.
Friday, November 01 2013
At first glance, metal detecting seems like the least demanding form of prospecting for gold. But it has its share of challenges, too, just like sluicing, drywashing, or panning by hand. Whether you've been swinging a metal detector for years, or just purchased your first machine, there might be a few things you could do to increase your chances of uncovering a piece of buried gold.

The Gold Cube is now shovel ready! Take the hassle out of pre-classifying with this NEW Gold Banker (manufactured by Gold Cube). The 3/16th punch plate topper acts like a huge classifier. Already own a Gold Cube? Buy the top part only and then simply attach the stand extensions to your existing Cube stand and attach the 5 foot hose and you are ready to go for the gold!
The Gold Banker is constructed of thick ABS material with built in adjustable spray bar. The punch plate is anodized or stainless steel (your choice) that simply slides into the unit. Stainless is the best choice for salt water use, or just give the less expensive anodized version a good rinse with fresh water after use. Learn more about the Gold Banker.

Drywashers are like highbankers, but they do not use water, making them excellent tools for recovering gold from dry material in desert areas. A dry washer is basically designed to be a waterless sluice. It separates gold from sand and other waste material with pulsations of air, vibrations, and static electricity instead of running water.
The top portion of a drywasher is called a hopper and consists of a box covered with wire screen. The screen is called a "grizzly." Dry gold-bearing material is fed onto the grizzly, which is mounted at a fairly steep angle. Thinner material, such as dirt and small gravel, falls through the grizzly screen and into the hopper. Larger material, such as rocks and sticks, roll off the grizzly and back onto the ground. Material from the hopper is then fed by gravity into the riffle tray below (looks like a sluice box), through an opening in the bottom of the hopper.
The under side of the riffle tray consists of a piece of stretched cloth that allows air to pass through the bottom of the riffle tray. A fan is mounted inside the sluice box and spins as air is blown up through holes in the bottom, usually by a leaf blower or another source of compressed air. Mounted on the fan is a weight that throws the fan off balance when spinning, and vibrates the entire box. This additional vibration assists in forcing flour gold to the bottom to be trapped, whereas lighter material is blown off.
Keep the following tips in mind, and you just might see the results of your drywashing efforts pay off even better:
• Moist soils and clay cause problems, so be sure to crush lumps of clay and dry your dirt in the sun (plastic tarps are ideal) before running through your dry washer. Surface soils might seem dry, but if you dig down a few inches, you may find moisture in the soil that will cause your sand, gravel, and gold to stick together.
• Double-check all the "throw away" rocks that get stuck in the grizzly before discarding. Scanning them with a metal detector is a great way to ensure you're not tossing aside gold-laden rocks. Another time to use your detector is on old tailings piles. These ordinary looking rocks could be laced with gold, yet were completely over-looked by earlier prospectors.
• Don't limited yourself to drywashing in "proven" areas. Because of the high costs associated with inaccessibility and lack of water, most desert regions have gone largely untouched by mining operations of yesteryear. A side benefit is that you don't have to go far off the beaten path. Virgin ground can be found in washes right off major roadways.
• Keep an eye on the terrain. Areas where the greatest amount of erosion has occurred are usually the areas where the highest concentration of gold values might be found.
• One of the best locations to look for gold is where the hills meet the desert and fan out. This is where flood waters from storms drop gold in the gullies and washes. There also may be more gold traps further up on hillsides. All it takes is one good storm to change the face of a desert landscape, so drywashing after a storm can potentially uncover previously hidden gold!
Gold Buddy drywashers are made in the USA and available in four sizes— Colt, Pony, Maverick, and Stallion. Each drywasher comes with a FREE "Working the Drywasher" instructional DVD, FREE shipping in most cases, and has a 5-year manufacturer's warranty.

Place your sluicebox in the flow of a stream or river so that the water enters the flared end and flows through the sluice. If the current is strong you may need to lay some stones against the edge of the sluice to keep it from washing away. The sluice should be set at a downhill angle that allows the material to briskly flow through it. The higher the volume of water available, the shallower the angle will be.

Placer gold is any gold that has been freed from solid rock by weathering. There are several types of placer gold, including Eluvial (gold that has been pulled down hill through the force of gravity), Alluvial (running water has deposited the gold in streams and rivers), and Beach (gold is concentrated by wave action). Eolian placers form by wind action in arid regions. Material broken from the bedrock disintegrates and the winds carry away the surface sand and dust, leaving behind a layer of cement-like mixtures of quartz, schist, and other material. Gold, being heavy, settles in this sun-baked "pavement." For the most part, eolian placer gold can be found just about anywhere in a desert landscape. Look for obvious signs of wind erosion and soil depletion, or a flat area on a wind-blown hillside where vegetation grows. If seeds were trapped in a depression, perhaps gold was, too. Desert miners have learned from experience that since wind has carried away most of the lighter sand and topsoil, eolian gold is usually very close to the surface or even on the surface. You can sometimes spot shiny flakes and tiny pickers practically laying on top of the ground, or a metal detector will find anything that is hidden just below the surface.

Ever wonder how much gold has been mined in all the world? The best estimate at the end of 2011 is that around 165,000 metric tons (or tonnes) have been mined in all of human history. That’s about 181,881 ordinary tons or 363,762,732 pounds, or 5,820,203,717 ordinary ounces. Gold typically is measured in troy ounces, which are a little bigger than ordinary ounces (a troy ounce is 31.1034768 grams whereas an ordinary ounce is 28.3495231 grams). There are 32.1507466 troy ounces in a kilogram or 32,150.7466 troy ounces in a metric ton.
Over half of the gold that is mined gets used for jewelry. 18% constitute official holdings (as in central banks of nations), 16% take the form of investments, 12% is for industrial uses, leaving 2% unaccounted for. Since jewelry is the most common use of gold, gold consumption worldwide is most easily gauged by gold jewelry consumption. India is far and away the biggest consumer of gold, followed by China, the USA, Turkey, Saudi Arabia and Russia.
As for the amount of gold that's used for monetary and investment purposes, In 2011, about 2,100 metric tons of gold appeared in what are known as exchange-traded funds (ETFs). As of 2009, the International Monetary Fund (IMF) held 3,217 metric tons of gold. In 2010, the central banks of nations held a total of 28,398 metric tons of gold.
Statistics can be interesting but the burning question on prospectors' minds is "What's happening with gold prices?" Since gold prices have TRIPLED in the last 10 years and gold price trends since 1900 continue to point up, there's never been a better time to find your own gold! And with the price of gold skyrocketing, you don't have to find much to completely pay for your equipment— and the rest is pure profit!

What's the Difference Between a Karat, Carat, and Carrot?
The purity of gold is measured in 24ths called karats. 24K gold or 24-karat is 100% pure gold. 18K gold or 18-karat is 75% pure, and 14K or 14-karat is 58.3% pure. The value of gold can further be determined by its rarity of structure-- whether it is a nugget or wire gold or has specimen value.
Gemstones are weighed by the carat (notice the difference in spelling) -- which is 200 milligrams or one-fifth of a gram. There are 5 carats in a gram. In addition to weight, the value of gemstones is also set and judged on their color, clarity, and cut.
If you're hungry, choose a carrot!

Fool's gold, iron pyrite, mica... no matter what you call it, at first glance it looks like real gold and sparkles like real gold in the sunlight or when viewed under water, but how do you know FOR SURE if those gleaming flakes are worth something... or exactly nothing?
The quickest and simplest test is to examine your sample in the shade, not in the sunlight. Real gold retains its yellow sheen even in shadow, whereas fool's gold does not.
Also keep in mind that gold is one of the heaviest elements known. Pure gold has a density (specific gravity) of about 19, which means that it weights about 19 times as much as an equivalent amount of water. On the other hand, mica, often mistaken for gold, has a specific gravity of about 2.3. Real gold sinks to the bottom of a gold pan; flakes of mica typically float.

Simply put, gold comes from rocks. Huge rocks, in the form of mountains, are pushed upward by heat and pressure from deep inside the earth, and then the rocks are worn down by wind and water. Through water erosion, gold often becomes separated from the rocks, forming the rich placer deposits we're all looking for.
The kind of mountains that are most likely to contain gold have been subjected to earthquakes. Earthquakes produce "faults" which are places where the tension of the growing mountain became so great that part of the ground pulled away, leaving a long scar. Locating a fault line or "outcrops" (ordinary soil pockmarked with monoliths and low ridges of sold rock) are important to prospectors because these areas often point to places where minerals were thrust into the rip in the earth during a geological event. Normal erosion washes gold into waterways below, and gold being heavy, settles naturally along the way— on the inside edges of bends in the stream, in whirlpools where two creeks join, in and around natural obstructions such as rock crevices and boulders, in the roots of river plants and trees. Gold is often found mixed with concentrated strata of fine black or red sand. Black sands that are iron oxide are magnetic. Red sand is composed of tiny crushed garnets. Continued here...

If you're looking for a Power Sluice /Highbanker that is
* HEAVY DUTY
* HIGH CAPACITY
* EASILY TRANSPORTABLE
* DESIGNED AROUND PROVEN RESEARCH
Then check out the CC690! This is a water operated, centrifugal concentrator and is capable of processing large volumes of material without the need for pre-classification. With the CC690, not only is the force of gravity at work to trap gold, but the very force of the water itself is used to create high energy vortices that trap and hold gold particles against the matting. These forces combine to help the smaller particles work their way deep into the looped, vinyl fibers of the matting and on down to the grooves of the underlying, v-ribbed rubber mat where they remain until it is time to perform the clean up operation. In other words, the CC690 Power Sluice / Highbanker helps small scale gold miners like you extract the greatest percentage of gold possible from the gravel you feed into it! Purchase the sluice only, or as a package with pump and hoses included. Learn more here.

If you're like many prospectors, you collected a few buckets of concentrates this summer and figured you'd process them during the winter when you had more time. Now those buckets are probably in the garage, the basement, and taking up space in the shed — and someone else in your household might be complaining that they are in the way! Three great products can help you process those concentrates more easily and quickly, especially if it's fine gold: Desert Fox automatic spiral panning machine, the Magna Two, and the Catch-It II Water Table. All of these machines are simple to operate. You won't need much practice before you discover how efficient and easy they are to use. With gold around $1,400 an ounce, the sooner you get those concentrates processed, the sooner you can reap the monetary rewards of gold prospecting!

When you are sampling for gold in a streambed, you should nearly always be looking for hard-packed material. “Hard-pack” is created at the bottom of waterways during major floods and storms. The reason that hard-pack is important to a prospector is because gold nearly always concentrates at the bottom of hard-packed layers. Therefore, it is nearly always important for a prospector to target his or her sampling efforts to reach the bottom of hard-packed streambeds.
Gold is about six times heavier, by volume, than the average weight of the sand, silt, and rocks that make up an average streambed. Because of this disparity in weight, when streambed material is being washed downriver during a major flood, most of the gold will quickly work its way down to the bottom of the streambed material. Because the gold is so much heavier, it will work its way down along the river-channel more slowly than the other streambed materials. During major storms, most of the gold moving in a waterway will be washed down across the surface of hard-packed streambed that is not being moved by the storm. At some point during the storm, gold becomes trapped out of the turbulent flow by dropping into cracks and holes. Streambeds form later in the storm, when the water-turbulence tapers off enough to allow the rocks, gravel, sand and silt to drop out of the flow and form a layer along the bottom (over top of the gold).
Streambed material that lies on top of the gold will nearly always be hard-packed. Why? Well, if there is enough force and turbulence to move substantial amounts of gold in the waterway, then there is also enough force to create a naturally-formed streambed on top of the gold as the same storm and flooding dies down.

To learn about gold mining of yesteryear, take your family on a tour of the authentic Crystal Gold Mine in Kellogg, Idaho. Dress warmly, don a bright yellow hard hat, grab a flashlight, and follow your tour guide into the underground world of gold mining. For over 100 years, no one knew this mine existed. The original prospector simply disappeared, leaving his mine car, track, tools, and high-grade gold ore behind—sure signs he intended to come back, but strangely never did. During the years that the mine was lost and undisturbed, beautiful turquoise-colored smithsonite crystals formed on the walls. You’ll also see gold and wire silver, too. After the tour, pan for gold outdoors under the tutelage of your mine guide. Even if there’s no flash in your pan, you might find a star garnet—Idaho’s state stone. And what a rare souvenir that would be; these garnets naturally occur in only two places on earth—India and Idaho.

Why spend hours separating the magnetite from your concentrates when the Magna-Two can do it in minutes? Magnetite and other magnetic sands slow the finishing processes of gathering fine gold. By removing this magnetic material first, your spiral wheel or blue bowl can be more efficient and will catch more gold.
Here's how Magna Two Fine Gold Recovery works:
* Turn the vibrator on, add dry concentrates to the top of the tray.
* Lift the top of the hinged tray and the magnetite slides into back tub.
* The magnetite will stick to the tray while clean concentrates slide off.
Magna-Two measures 7.5" wide x 17" long x 7.5" tall. Weighs about 5 lbs. Batteries and tubs not included. Requires 8 AA batteries. Watch the Magna Two demo video here.

If you're struggling with how best to RECOVER FINE GOLD, the CATCH-IT II WATER TABLE is designed as the ultimate tool for fine gold recovery! The aluminum table has a unique green surface that attracts gold. Just sprinkle clean gold concentrates onto the water covered table. The flowing water stratifies the material, allowing the gold to separate and stick to the green surface while the blond and black sands float away. All that is left to do is to brush the gold to one spot and snuffer it up! The CATCH-IT II II WATER TABLE is an amazing finishing machine for only $249 that comes in a rugged plastic tote to protect the table from damage when in transit or storage. Included in the tote is the water table, a tailings bin, a 110 VAC submersible mini-pump, one small brush and instruction sheet. Get more information and watch the demo video here!

Your chances of finding gold in the desert are about as good as finding gold in wet areas. Study the geology and history of the area where you're prospecting or detecting, and you'll have a distinct advantage. Many large-scale mining operations of yesteryear didn't set up in the desert simply because their equipment needed lots of water, and the desert was much more inaccessible a hundred or more years ago. They didn't have portable Gold Buddy drywashers or variety of spiral gold panning machines that operate on just 3 gallons of water like we do now. So that means less competition! Just like in the mountains during spring snowmelt, one big rainstorm in the desert can change the landscape forever and uncover gold that had been hidden for centuries. Perhaps one of the best locations to look for gold is where the hills meet the desert and fan out. This is where the water slows down during storms and drops gold in the gullies. There also are likely to be more gold traps further up the hillside. Concentrate much of your effort in drywashes, dry streambeds, and canyons. When water flows during a flash flood, areas where the greatest amount of erosion has taken place are natural areas for gold collection. In some areas, like Quartzsite, Arizona, nuggets can be found with a metal detector just under the ground's surface, or even on top of the ground. If you find one piece of gold on the surface of a dry placer area, it is likely that there are more pieces of gold in the immediate area because gold generally does not travel alone. So don't call it quits after the first find— keep looking!

After practicing a while, everyone develops their own personal technique for gold panning. Some vigorously shake the pan, some gently swish it from side to side. There are about as many different techniques, tips, and tricks as there are types of gold pans! In truth, there is no real "right" way to pan for gold-- if you're gettin' a flash in the pan, you're doing it right! If you're just getting started, though, and don't know where to begin, follow these easy steps and before long, you will develop your own methods:
1. Fill pan about half full of gravel, small rocks, and sand collected from the stream bed
2. Put the pan under the water's surface, break up large lumps of clay or dirt, and remove stones
3. Continue to hold the pan level under the water with your hands on opposite sides, and tilt the pan forward, away from your body, and down slightly. Rotate and shake it side to side to let gravel and sand dribble out the front. Pick out the rocks.
4. Repeat step 3 several times until most of the material is removed, leaving less than a cup of fine-grained dark material overlain with a thin layer of light material at the bottom of your pan.
5. Rotate the pan in a circular motion. Notice how the water separates lighter material from heavier.
6. Stop rotating and hopefully you'll see a flash in the dark material remaining in the bottom of your pan! Use tweezers to retrieve the gold and place in a vial for safe-keeping.

Thanks to the modern day gold rush, the Desert Fox automatic spiral panning machine has become a best seller! Most prospectors tend to favor the Variable Speed model, but it also comes in Constant Speed. Have you seen this machine work? It is very compact, weighs under 10 pounds, folds up and stores neatly in its own Action Packer tub. You can take it anywhere! Operate it right out of the tub, or remove it from the case and use it in a stream. The Desert Fox is aptly named because it was designed to conserve water and will operate on just three gallons. Recovers an amazing amount of flour gold so you never lose even the smallest pieces (which all add up!). Operates on any 12-volt automotive battery (not included) or even a 35 watt solar panel. Ships complete with an easy-to-understand owner's manual, a video, and a bag of practice sand containing real placer gold so you can get acquainted with your new machine even before you leave the house. You won't need much practice, though, because in no time you'll discover how efficient and easy it is to use. With gold at over $1,000 an ounce, get a Desert Fox automatic spiral panning machine and get out there and get your share!
