Advancements in Non-Toxic Gold and Silver Leaching

The non-toxic thiosulfate is actually the medical antidote given to people for cyanide poisoning. By accomplishing both neutralization and metals recovery, this process creates an economic and environmentally attractive process.
The Perfect Summer
Within the first 3 hours he and I had found pocket after pocket of gold and couldn't wait to tell Levi of our treasure.

Don’t try to swim against the current because you will waste much energy in an effort to conquer the river. Just let it take you downstream.
The Jenkins Mine Project, Conclusion—Recovery Operations & Summary
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.
Dredging The Outside Bend
This stringer was where it was not supposed to be, and it contained nuggets that were not supposed to be there.
Small-Scale Hard Rock Production
So far this year we have recovered over three pounds of gold and the hard rock veins seem to go on forever. We now have three claims that can produce good enough gold to set up a productive operation.
A Few Methods for Sampling Hardrock Deposits
With a little homework and a methodical approach to sampling, a prospector can determine if a deposit is worthy of more of an investment...
