High Sulfidation Epithermal Deposits
November 2019 by Chris Ralph
They tend to be big, coming in large to extremely large sizes. They can also be amazingly rich and produce huge amounts of very high-grade ore.
They… create negligible fumes and much less fly rock than blasting. Below are some tips on maximizing your effectiveness with these tools.
The whole purpose of sampling mineralized ground is to measure the values in a small volume of material that would be representative of a much larger volume of similar material. The key word is representative. Chemical and fire assaying will not accurately represent placer deposits by themselves.
This project taught me that you don’t need to be Albert Einstein to apply a little science to your prospecting. I learned that most of the science related to suction dredging is actually common sense. All we need to do is take the time to apply it.
Present conflicts and realizations having to do with dependence on China have illuminated the fact that suction dredge miners have a vital role to play and are an ignored and untapped domestic resource—until now.
When I started dredging a short distance downstream from that feature I realized that I was into a major paystreak and much of the gold was coming right out of the upper gravel. I could see the chunky pieces falling out of the gravel as they were pulled into...
The 316 Mining Company has not been all that successful, but does not ever seem to learn from their past mistakes.
I’ve been in enough mines to know better, and I mentally kicked myself several times. That was a close call…
