April 2012 by W. Dan HauselThree homonyms come to mind when I think of gemstones, gold and vegetables: carrot, carat and karat. Let’s look at carrot first.
• "...just about more than I can stand."
• "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..."
• "...New Prospecting Club in the Southeast."
• "...9 ounces...in two weeks."
• "...It's no secret..."
We import nearly all of our REEs from China, so it’s critical that we find and continue to develop domestic resources of these elements.
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.
Q: Is there a correlation between fault zones and mineralization of economic metals?
Because quartz and gold may be deposited together across a considerable range of temperatures, not all quartz veins are the same, and there are several different types of gold-quartz deposits.
Because tungsten minerals are heavy, exploration can be done using stream sediment samples. Prospectors looking for gold have found scheelite or wolframite in their placer concentrates, and in some cases this has led them to make important tungsten finds.
I am going to keep to the basics of surface indications and visual clues in the rocks and minerals themselves that help me find gold-bearing veins in this classification of deposits.
