Critical Minerals: Tungsten
July 2017 by Chris Ralph
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.
Only the famous Kennecott copper mine was able to continue operating through the Depression owing to the exceptional richness of its ore.
In 1877, a prospector named Ed Schieffelin discovered silver in “the middle of nowhere” and staked two claims: “Tumbstone” and “Graveyard.” Soon a town and mining district were organized and acquired the name “Tombstone” after making a spelling correction.
Narrowing down a closure date will allow you to check the commodity price during that time and possibly confirm that a low price, rather than a lack of ore, was the driving force that closed the operation.
There is a major change coming in the economy of the world and now is the time for prospectors and miners to grab a ticket and get on board.
…it was immediately evident the previous owner had not been using a detector. During just a few months of working the dumps part-time, he recovered gold in quartz specimens valued in excess of $40,000.
Many miners know that lead is very commonly associated with silver values, but the truth is that it is also associated with gold values in many locations as well.
