Prospecting & Detecting
The Value of Evidence
February 2019 by R. V. Larson
That prospecting effort you are about to spend your time on...is it worth your effort? If you are going to devote your time to it, you will need all the facts you can get.
Sampling Placer Stockpiles
Sampling other people's stockpiles or dumps has some inherent risks that sampling undisturbed ground does not have.
Following Clues to an Old Mill and Vein Strike
My last update on this adventure was in the April 2012 issue and involved our search for the northern extension of the Cedarberg Mine. At that time we had found it and we were in the process of returning for some detecting when Mother Nature struck with a late rain and snow storm.
Mining Pegmatite Deposits
With successively lower temperatures as the water mixture cools, new sets of minerals are formed and many of those stable at a higher degree of heat became subject to alteration as the temperature progressively moved lower.
Refractory Gold Processing
After your excitement peaks when you first receive the high gold assay from the vein you just exposed, you ponder how you will extract and sell your gold. You will need to develop a flow sheet for your process to optimize your recovery and minimize your costs and permit requirements.
Following the Clues
It took me awhile before I finally got a nice mellow signal. My nugget turned out to weigh in about two dwt (pennyweight). Over the next few hours, we all picked up a few more nuggets apiece.
Revisiting The Old Mini Patch
Today, the greatest gold rushes occur due to technological advances capable of discovering gold where it once was extremely unlikely or difficult.
Time Well Spent
Time is a commodity which if traded would dwarf the price of gold. Nobody has enough of it; we can’t make more of it; and whether squandered or spent wisely, once gone, it’s gone forever. To find gold we have to spend time.
