After a guided tour through the mining operation at Barrick's Golden Sunlight Mine just outside of Whitehall, I was impressed to know what lengths men will go for precious metal. It would require at least a base knowledge of chemistry and geology to understand the finer points; but in the simplest terms we can summarize this particular type of mining: rocks with significant gold content (the market decides what is 'significant') are broken apart, lifted from the earth, and pulverized into dust with giant machines. Then, using chemicals and specialized equipment, the dust particles can be manipulated via their different densities and other specific properties. Still with me? After a dozen separations or so, the mine can effectively turn out bricks of "Dore'' which is about 70% gold, 20% silver and the rest mostly copper. These are taken to an off-site location to be further refined and purified. by Will mUhlenfeld w w w. d i s t i n c t lymo nt a na .co m 39
