  • Some believe that the reason policemen in the USA are nicknamed "cops" or "coppers" is to do with their uniforms which used to have copper buttons.
  • Slag dumps in Asia Minor and on islands in the Aegean Sea indicate that man learned to separate silver from lead as early as 3000 B.C.
  • Nevada lands directly affected by mining is one tenth of 1%. That is not bad considering that it is 110,561 square miles and ranks 7th in the United States in size. It ranks 43rd in population at 800,493 people (1980 census).
  • In ancient times salt was traded ounce for ounce for gold. Salt was once made into 'coins' and 'cakes' in china and the Mediterranean for use as currency. Several cultures levied taxes on salt.
  • Gold was first legalized as money as early as 1091 BC in China as an alternative to silk. Gold is still the only universally accepted medium of exchange.
  • Coal was used widely in England in the 1600's because of wood shortages. Brewers had decided to try to dry their malts with coal generated heat but the fumes were absorbed by the brew, ruining the taste. The brewers found, however, that the undesirable gases could be eliminated if the coal was first heated in an air tight oven. Thus the discovery of the coke making process that has since been an essential part in the making of iron and steel.
  • Gold is the most ductile (easily molded or shaped) of all metals, allowing it to be drawn out into tiny wires or threads without breaking. As a result, a single ounce of gold can be drawn into a wire five miles long. Gold's malleability is also unparalleled. It can be shaped or extended into extraordinarily thin sheets. For example, one ounce of gold can be hammered into a 100 square foot sheet.
  • The greatest gold rush in U.S. History began when gold was discovered at Sutter's mill in California by a man named James Marshall on January 24th, 1848.

  • 2000 years ago the Chinese used an alloy of nickel.
  • Pure nickel was first isolated in 1751 by Axel Cronstedt, a Swedish scientist.
  • The Soviet Union is the worlds top nickel producer weighing in at about a fourth of the world total in nickel production.
  • Nitric acid was one of the first acids known. Many alchemists of the Middle Ages used it in their experiments.
  • Salts are taken from the ground and purified...and end up on your kitchen table. Deposits were formed by the evaporation of large parts of oceans millions of years ago. In these natural formations also occur calcium carbonate and potash. Underground salt deposits are found all around the world.
  • There are two methods of removing salt form the ground...room and pillar mining and solution mining.
  • Of the 50 states in the union ALL of them mine something.
