Strategic Metals—Part II
December 2013 by Bill RichThere are literally thousands of abandoned wasterock and ore dumps that dot the United States that could hold many tones of strategic metals.
When prospecting for lithium, after confirming for macro attributes through research and field work, including examination of surface geology, the main tool is an accurate lithium assay.
Gold specimens that include visible crystal formations are among the rarest, most attractive and most valuable forms of gold to be found.
It is not necessary to have a PhD in geology, but you need to know the basics, so that’s what I am going to try to dig into here—the understandable basics of these gigantic gold deposits.
It also happens sometimes that glaciers will bury valuable placer deposits. This occurs when the glacier goes over the top of an existing placer deposit.
While both zinc and lead deposits also are enriched by the surface weathering process, in part two we will look at the enrichment process for copper and also gold deposits, and at the interpretation of leached outcrops to figure how rich the concentrated deposits below them may be.

• "I hope you can answer my number one question..."
• "...I still go out and mine a little at my old stompin' grounds in Siskiyou County..."

• "...It's no secret..."
Lately my mind has been involved with group 4 of the transition elements, namely titanium, zirconium, and hafnium. They all have similar chemical properties. Of greatest interest to economic geologists and miners is that these valuable elements often occur together in sands.
