New Zealand Clay Mines

Epithermal gold deposits are among the richest gold deposits in the world with some bonanza grade ore shoots containing more than 1000 gt gold, or in other words, a kilogram of gold for every tonne of rock mined.Unfortunately, the tonnage of ore in epithermal veins is typically small compared with other types of lower grade gold deposits.Gold mineralisation within epithermal veins.
