Have you ever seen gold in a hairline crack and reached for your crevice tool, screwdriver, or rock hammer; and then spent the next 20 minutes prying, scraping, and/or prodding to get it out of that crack, wishing all the while that this tiresome process wouldn’t take quite so long? Well, the answer to quick gold removal from hairline cracks as suggested and demonstrated by veteran miner Dan Fifer is to go to your local auto parts store and purchase a muffler/tailpipe air chisel. Prices vary from $39.95 to $89.95, chisel included.
Using an air chisel, you can rip up a four-foot crack containing gold in one to five minutes, and then move on to either pumping more overburden or to the next uncovered crack. The amount of time spent depends on how deep the crack is and/or how hard the bedrock is.
My partner Chuck and I found that the speed of our operation dramatically increased when we began using our air chisel. If you do decide to use a chisel, be sure to oil it once every day. We use Marvel Mystery oil each evening after we’ve finished dredging. In our dredging operation, we use a Pro-Mac 8-inch dredge with VW power plant, two pneumatic 100 PSI air compressors as standard equipment, and have two divers down at all times.
We added one additional air tank and 50 feet of air line to power the air chisel and provide extra air for the divers when the chisel is not in use. With the extra tank, we have yet to run out of air. The only draw back in using the chisel underwater is that the noise is quite loud, but you get used to it. So save time and bring in more of the yellow stuff each day; invest in an air chisel. You will be glad you did!
