Small Mining Operations
Wealth Beyond Your Wildest Imagination
September 2012 by R. V. Larson
“Wealth beyond your wildest imagination.” Those were the words that were used to inform me of how much gold was in a paleo channel that exists beneath the present channel of the Similkameen River in the State of Washington; words that have echoed in my mind for the past sixteen years.The Smell of Gold -- Part II
While mapping, I also found rock chips in the soil that were characteristic of the same wall rock alteration that occurs adjacent to the known lodes in the greenstone belt.
Proper Assaying of Placer Samples
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.
Cyanide-Free Gold Separation
Some ores—mostly those with a high free gold content—are very amenable to gravity concentration. Well oxidized ores containing coarse gold are usually best for non-cyanide processes. Ores with significant sulfide content may require the...
Pumping Water With Solar Power
Solar energy can be used for any size placer or hard rock mining operation. It is most practical for small and longer-term operations provided your mine is not located in a dense forest.
PLP Update: Back to The 'Swamp' on Behalf of Small Miners
We spent the morning in a meeting with one of the higher-ups at the US Forest Service. I presented him with 412 complaints received from our readers, along with a summary of the complaints to make his job easier.
What To Look For—And Look Out For—In A Placer Mineral Report
Buying a placer claim or investing in a placer mining property comes with plenty of financial risks. You need as much information as possible about the mineral deposit in order to minimize those risks.
Gold Deposits of Montana
Historically, Montana has been an important gold producer, in terms of both lodes and placers, and it still produces gold for the prospector today.
