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...
I’ve been taking a look at the mining and uses of a number of critical metals in series of articles, and it’s time to take a look at antimony.
The Wyoming State Geological Survey announced ten new geologic maps have been completed and are now available.
Honestly, I don’t believe it is likely there would be a glory hole where they described one at the bottom of the waterfall because plunging water with enough energy to scour out a large hole in bedrock would have the scouring ability to grind up and...
