  • Learning Goals: -What is an ore deposit?

    If a deposit area has 6 tons of copper in 1,000 tons of ore rock, what is the grade? 6/1000*100=0.6% Typical mines today have ore grades of only 0.6 percent copper. Since metal concentrations occur at much lower grades, the copper concentrations are measured in parts per million (ppm).

  • Mineral Deposit Value How to Calculate the Potential

    As you can see in the example above, the deposit does not have to be enormous in size (only 500 meters long by 100 meters wide) to contain a valuable deposit (approximately $6 billion worth of minerals). However, in order to be as realistic as possible about this valuation, you can not assume that the complete ore body contains the same grade (i.e. 2% copper and 1.5 gram per tonne gold).
