Exploring Placers with Auger Drills
June 2014 by Jim HalloranAugers can be used effectively for placer exploration with certain limitations.
These days they employ the use of metal detectors and carefully scan the shattered rocks, hoping to hear that sound we detectorists love to hear.
Q: How do I improve my small-scale mining operation’s gold production?
Federal and state regulatory agencies often cite mercury and methyl mercury in our waterways as a major factor for further restrictions on placer mining, and on suction gold dredge mining, in particular. However, these regulatory agencies are minimizing selenium and its neutralizing effects.
I thought it might be worthwhile to take a look at the basics of this important mineral separation technique and how a miner can use it to recover the values out of an ore.
Another little gem of equipment he built was a nifty sample splitter. In order to get accurate assays, you need to have really good, representative samples for the assayer to process.
With the exception of well-established operators with proven reserves and years of field experience, the high price of gold brought a flood of speculators, con men, and real estate brokers into the mix who were not previously engaged in the gold mining market.
...I decided to excavate the semi-frozen high-bank that was resting on a soft shale bedrock footing. Within three feet, I encountered an intrusive!
