20 1 Metal Deposits – Physical Geology

Looking at copper for example we can see that while average rock has around 40 ppm (parts per million) of copper a grade of around 10 000 ppm or 1% is necessary to make a viable copper deposit In other words copper ore has about 250 times as much copper as typical rock
