The PIGMI—a DIY Crevice Tool
April 2017 by Tom LeftwichI’ve had great success using it to gather gold from crevices. I’d like to share the design with all of you gold miners reading this article and hope that you get as much satisfaction building and using it as I did.
When you think about the extremes to which a miner will go to get a little gold, it occurred to me beach gold could be "easy pickings."
Most of us know making a profit as a small-scale miner is difficult; however, sometimes we combine luck with a little skill and bring home a few ounces of the yellow stuff.
Most prospectors understand placer mining a lot better than hard rock mining and don’t realize the amount of work that goes into processing different types of hard rock ore.
...a large number of these aspiring miners developing their operations seemed to have missed "Placer Mining 101" somewhere along the way.
This concept of detecting does not always work as we sometimes get a week or so where the temperatures rise to 116°—sometimes more.
Down around 10 or 12 inches I hit a large cobble that appeared to be one type of hot rock for this area. I thought bad things about the new technology until I checked the rock.
After your excitement peaks when you first receive the high gold assay from the vein you just exposed, you ponder how you will extract and sell your gold. You will need to develop a flow sheet for your process to optimize your recovery and minimize your costs and permit requirements.
