I have found it is not necessary, during weekend or vacation gold mining trips, for women to be resigned to the camp cook and dish washer position. There is an easy, hassle-free way to spend your time and have it turn out uniquely rewarding at the end of the day. This method is called “crevicing”. It requires few tools, no back breaking work and can be enjoyed by the whole family. My kids and I have creviced in desert dry washes as well as along streams and rivers. The final panning of the material we’ve recovered has always kept us going back for more!
Crevicing gets it’s name from the cracks and crevices found in exposed bedrock. These are known gold-catching areas. It is amazing how deep gold can settle inside these cracks. The job of crevicing involves breaking the crack open wide enough to allow you to get out all the material that it contains. This isn’t hard. Within a short time you can become a pro at it. The tools of the trade vary. it’s best to have a chisel, rock pick and a gold claw. A bucket is needed to put your material in, along with a #4 classifier. If you classify at your work site, you will not have such a heavy load to lug back to camp. Add a tablespoon to your tools for scooping out material in places where your hand won’t fit.
The very best piece of equipment you can add to your operation is one of the several models of motorized vacuum suckers now available on the mining market. It is not a necessity, but there is no comparison to the ease and thoroughness of using one. These vack machines are extremely lightweight and strap to a pack frame for carrying on your back. Instead of spooning or scraping out your material, you can simply vacuum it up. These motorized vacuums are also good for sucking flood gold out of moss on high water rocks. This is probably the easiest job of all.
Here is where you can find a special offer on the world’s best vack machine.
But do not fret, if you don’t have one. When I started crevicing, I used a hammer and a screwdriver!
After you’ve gathered your tools together, hike up the river or along a dry wash, wherever you happen to be. Look for low bedrock exposure, because gold is heavy it tends to concentrate more readily in the low spots. Preferably find a crevice in the rock running toward the river instead of along it. These usually catch more gold. Remember also, the bigger the crack, the larger the gold that could be trapped inside.
Start working by loosening everything inside the crevice with your gold claw or screwdriver. Scrape it out and into your classifier on top of your bucket. Chip around any rocks jammed in the way with your chisel until they come free and you can pull them out. Sometimes you can knock off the sides of the crack to widen it by hammering. This enables you to work farther and deeper into the crevice. If you reach a point where you cannot fit your hand, use your spoon; scraping away until the crevice is clean.
This type of bedrock is over 500 million years old. It’s origins come from the ancient mountains that used to be here. Quite often it appears harder than it is; but if you keep digging and scraping, it is actually soft enough to keep breaking away.
Take everything! Moss, sand, dirt, anything that you can loosen. Clean the crevice out as much as possible or as far as you can reach. If you finish one spot and have not gathered enough material in your bucket, move to another spot.
The hardest part about this whole method of mining is carrying your material back to camp. You can regulate this to suit you. Or, if you have kids or a partner, you can share the load. That is, unless water is near the place where you are working. In that case, you can either pan or sluice your pay-dirt right there.
Crevicing is fun and rewarding for the whole family. You will probably recover lots of fine gold and once in awhile a nice nugget or two. Your back will not hurt and you will not be dog tired when you are through, either! If suction dredging for gold is not your cup of tea, and you do not want to spend extra dollars on other equipment, crevicing may be just the thing for you. No noisy engines, no gas to haul, nothing to break down. Just peace and quiet, and the enjoyment of a job well done.
