Why Haven't They Mined This Claim?
May 2011 by Jim HalloranImprovements in mining equipment and techniques, along with a higher gold price, make many mining properties profitable today that may not have been in the past.
The evaluation must also consider the gold fineness or purity. The purity of the Sugardaddy nuggets is estimated at 850 fineness, meaning 85% is gold (Au), 12% is silver (Ag) with 3% being other gangue alloyed metal.
There is reason to believe these stream valleys are still rich with gold, silver and copper.
Many of the Sixteen to One’s challenges arise from its unusual geology and the pocket characteristics of the ore deposits.
With the exception of well-established operators with proven reserves and years of field experience, the high price of gold brought a flood of speculators, con men, and real estate brokers into the mix who were not previously engaged in the gold mining market.
For this article, I am focusing on industrial production plants that can handle 10 cubic yards per hour or more and would be fed by a loader or other heavy equipment...
So you think you have an ore deposit? The work has been long and hard, but there are a few drill holes, lots of samples and assays. The data is in a reliable computer and there may be a mine at the end of the tunnel. What is the likelihood of a profitable operation? Can you raise capital for development or exploration?
All these decisions and more depend on the richness of a claim—something that is determined by sampling. But sampling isn’t cheap, and even collecting the samples can be more difficult than it appears on the surface.
