Sampling for Success—Part II
April 2020 by Chris Ralph
The first and most important thing of the sampling process is to try to be as unbiased as possible. There is a natural tendency to select rock that looks the best—even unconsciously.
The old timers typically washed these areas down to bedrock, and some areas appear terraced. I would imagine this is because these hydraulic mines were generally where the miners found old Tertiary river channels on the sides of mountains that were gold-bearing.
I got a signal but knew it was small. Still, I was very happy to find something. I continued and got another signal. Yes! A bigger nugget! Then I got another signal.
Normally we do not cover gem and mineral shows, but this one is a little different. The Tucson (Arizona) Gem and Mineral show is the sales source for so many small mining operations, I felt I had to address this show and its possibilities for the small miner.
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.
They must have assumed the paystreak was spotty and had been mined out, so they never mined as close to the side of the valley as they should have.
While recovery rates are important, they must necessarily be secondary to the volume of material processed. Running more material at lower recovery rates is generally preferable to increasing the efficiency of the system.
My plan was to go up the canyon along a ridge and then drop into the canyon whenever I came across a spot that might give me reasonable access.
