Strategic Metals—Part I
November 2013 by Bill RichA bill was introduced and passed by the House of Representatives earlier this year that should make the exploration and opening of a mining operation faster and easier.
From time to time I’ve been doing a series on critical metals and how important they are to our complex and technological society. This month we are going to take a look at copper, and how important that metal is to our modern lives.
Arizona is well-known for its copper-gold porphyries and massive base metal-gold sulfide deposits such that primary gold deposits in the state are often overshadowed.
Alaska is getting a lot of interest these days, not least because of all the gold prospecting shows on television. Hardly a month seems to pass without some new prospecting show being announced, and a couple of the most popular feature Alaska.
There are several common ways that new mineral crystals form and grow. Perhaps the simplest is when minerals form through the cooling of molten rock and the atoms bond together into mineral crystals.
Some scattered reports say that gold may have been washed from streams here as early as the 1840s, but the undisputed major discovery came in 1870.
The other opportunity that I see is in seeking unusual types of deposits. Specifically, the prospector would be searching for the stuff no one (or almost no one) is searching for. These deposits are effectively hiding in plain view.
