Fortunately, there are products on the market that can address these problems and make a small-scale mining operation feasible.
Science has shown, over the past few centuries, that there is a direct correlation between certain plants and their geophysical surroundings.
In developing a mineral property or mining claims, one of the first goals is to identify and quantify valuable deposits. The classic method of doing this is by drilling holes into the ground to sample what is below the surface. The problem is that one or two holes usually are not going to tell you a whole lot...
Critical minerals are products that the government has designated as critical to our national interest because of both their potential military and industrial applications.
I get a number of questions from people about testing and treating hard rock ores. The simplest way, but also an expensive one, is to just have an assay test done by an independent assay firm. As an alternative...
Centrifugal bowls are very efficient, and with proper operation they can consistently achieve gold recoveries above 95% with gold of about 50 mesh size.
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.
