The 10-Ton Boulder: Expanding Grout Demolition
April 2021 by John Norman
Imagine you have located a source of virgin placer ore containing immense gold value. Now imagine that there is a 10-ton monolith of extremely hard gneiss in between you and payday.
Fascinated by the sapphires—and the gold that occured with them—he was soon buying parcels of property and setting up his own commercial-scale gravel processing plants.
Sampling gold placers can be rewarding, but remember to treat the samples so you are not high grading or low grading your results. Learn the rules and apply them so your samples are accurate.
“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.
I saw gold this summer. The kind of gold that I haven’t seen since ‘81. The kind of gold that rattles in the pan. The kind of gold that would start a stampede—even in 1898.
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.
This explains the large difference in particle sizes between placers and hydrothermal lode deposits, but also means that while the mining may be similar in some cases, the sampling and recovery techniques are usually quite different.
