These fluids are hot and acidic, and they come directly from an intrusion of magma that has come up from the mantle into the crust and brings with it gases and unusual minerals, including gold and silver. Gold-silver and other minerals are then,Low Sulphidation Epithermal Gold Deposits,23-07-2015· Low Sulphidation Epithermal Gold Deposits Although they are a product of the same igneous system, low sulfidation epithermals gold deposits are very different from high sulfidation. In low sulfidation the main control for Gold deposition, is fluid boiling – caused by a drop in the confining pressures the fluid approaches the surface.

Epithermal deposits are important sources of gold and silver, representing about 30% of total gold metal production per year. There are two principal styles of epithermal mineralization: low sulphidation (LS) and high sulphidation (HS)Epithermal deposits — Lucky Minerals,Epithermal gold-silver deposits are formed by geothermal fluids circulating in the earth’s crust.
