Gold Panning Techniques
There's more than one way to work for gold. From a basic hand pan to a full sluice setup, the method you use depends on where you are, how much material you want to move, what kind of placer deposit you are working, and how deep you want to go into the hobby.
How prospectors work for gold
Traditional Hand Panning
The most direct and personal way to look for gold. You fill a pan with gravel from the riverbed, submerge it, and use a combination of shaking and circular sweeping motions to wash lighter material over the rim while gold settles to the bottom. The technique takes a few sessions to develop muscle memory, but it's genuinely satisfying once you have the feel for it and can recognize black sand, fine gold, and heavier concentrates.
Hand panning is slower than other methods — most experienced panners can process a few pans of material per hour — but it costs almost nothing to get started and teaches you to read the water, identify likely pay streaks, and understand the material in a way that faster methods don't.
Sluicing
A sluice box is a long trough, typically two to four feet, with riffles along the bottom and a rubber mat underneath them. You set it in a flowing section of stream at an angle, then shovel material into the top end. Water flows through, carrying off lighter gravel while gold drops into the riffles and mat. After a session, you carefully remove the mat and rinse the concentrates into a bucket, then pan those concentrates down the rest of the way.
Sluicing lets you move significantly more material than hand panning — hours of work in a pan can be compressed into a fraction of the time. It's the most common step-up technique for hobbyists who want to get more serious.
High Banking
A high banker is essentially a sluice box mounted on a stand with a water pump attached. Instead of relying on the stream current, you pump water up to the top of the box yourself, which means you can work gravel banks, bench deposits, and dry areas away from the water's edge. Material goes into a hopper, water jets it through a classifier screen, and the slurry runs down through the riffle section.
High bankers are popular in Colorado because many of the best gravel deposits sit on benches above the current stream level, remnants of older waterways and alluvial channels. Getting water to where the gravel is makes all the difference.
Dredging
A suction dredge uses a gasoline-powered pump to vacuum material from the riverbed and run it through an underwater sluice box. It's the most efficient way to move substantial material and can reach gold that's settled deep into bedrock cracks. However, dredging is heavily regulated — some Colorado waterways are off-limits entirely, others require permits, and regulations vary by county, water body, and season.
Anyone seriously interested in dredging should research current Colorado state regulations and local rules before investing in equipment or planning a trip specifically for it.
Dry Washing
Used in areas without accessible water, a dry washer uses forced air instead of water to separate gold from desert or dry placer material. It's not a technique commonly used in Colorado's mountains, where streams are generally available, but it can be relevant in some of the state's drier western counties.
Metal Detecting for Gold
Not all metal detectors can find gold — most consumer models aren't sensitive enough for fine or shallow nuggets. Detectors built specifically for gold prospecting operate at higher frequencies and are tuned to ignore common iron interference. In Colorado, this technique is most useful in areas with known nugget history, tailing piles, old hydraulic workings, and mineralized ground away from stream gravel.
Where gold actually settles
Understanding how water moves is more valuable than any piece of equipment. Gold is heavy — about 19 times the density of water — and it drops out of the current wherever that current slows down.
Inside bends — Water on the outside of a river bend moves faster and cuts the bank. Water on the inside slows down and drops its load. Gold accumulates on the inside of curves, especially where coarse gravel and black sand settle together.
Behind obstructions — Boulders, bedrock outcrops, and large debris create eddies on their downstream side. These are natural gold traps and are worth checking with a pan or crevice tool.
Above and below waterfalls — The pool below a falls is a classic location. So is the bedrock immediately upstream, where material piles up against the lip and can hide placer gold in cracks.
Bedrock cracks and pockets — Gold sinks until it hits something it can't pass through. Crevices in exposed bedrock are where the most concentrated deposits are often found, which is why crevicing is one of the smartest small-scale prospecting techniques around.
Old high-water channels — Benches and terraces above the current stream level mark where the river ran in an earlier era. These ancient channels can still hold gold and are often worked with high bankers, detectors, and careful test panning.
Technique versus location
No technique will produce gold in the wrong spot. The most common mistake beginners make is picking a random stretch of river and panning gravel without thinking about where gold would naturally concentrate. Spend time reading the water before you dig. The right spot with a basic pan will beat the wrong spot with expensive equipment every time.
Common questions about prospecting techniques
How do you read a creek for gold?
Look for places where moving water slows down enough to drop heavy material, like inside bends, behind rocks, bedrock cracks, and shallow pockets where black sand collects.
What is the best prospecting method for beginners?
Hand panning is still the best place to start. It is cheap, portable, and teaches you how gold behaves in moving water.
Are all techniques legal everywhere in Colorado?
No. Methods like dredging and some motorized equipment are heavily regulated or restricted depending on location. Always check current rules before using anything beyond basic recreational panning.
