Regarding "Good Assays and Bad"
February 2012 by Chris RalphLast month I wrote an article entitled “Good Assays and Bad,” which gathered a few comments.
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.
Perhaps the most notable thing about skim placers is that they form on the top surface of gravel bars, as opposed to coarser gold placers where the weight of the gold particles allows the gold to settle down on or near bedrock.

This assay system of ounces per ton sounds simple enough, but the use of the metric system and the additional measuring terms of “grams per ton” and “parts per million” (ppm) has created some misunderstanding of ore value.
I’d like to offer some practical comments about staking and maintaining mining claims. Owning your own claim is the dream of many prospectors. I’ve made good money off my mining claims, both from the minerals I have found on them as well as from leasing out some of my claims to larger mining and exploration companies.
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.
It rained over four inches that night and the creek flooded both my backyard and my workshop. When I opened the door to my workshop Christmas morning, an unwelcome sight greeted me.
