Epithermal Gold Deposits Mining

The epithermal gold deposits are characterized as low sulphidation, epithermal vein mineralization hosted in a volcanic complex Deseado Massif. The mineralization is hosted in sub vertical dipping quartz breccias and veins in the volcanic complex. At La Paloma, the Sulfuro vein is a single vein structure consisting of breccia and vein.

Descriptive models for epithermal goldsilver deposits

Nov 07, 2018 Epithermal gold-silver deposits are vein, stockwork, disseminated, and replacement deposits that are mined primarily for their gold and silver contents some deposits also contain substantial resources of lead, zinc, copper, and or mercury. These deposits form in the uppermost parts of the crust, at depths less than about 1,500 meters below the water table, and at temperatures

Epithermal Gold Deposits Geology for Investors

Aug 13, 2021 Epithermal gold deposits are among the richest gold deposits in the world, with some bonanza-grade ore shoots containing more than 1000 gt gold-equivalent or a kilogram of gold for everyone tonne of rock mined. The tonnage of ore in epithermal veins is typically smaller than other types of low-grade gold deposits.

Nov 10, 2020 This report summarizes the primary characteristics of alkalic-type epithermal gold Au deposits and provides an updated descriptive model. These deposits, primarily of Mesozoic to Neogene age, are among the largest epithermal gold deposits in the world. Considered a subset of low-sulfidation epithermal deposits, they are spatially and genetically linked to small stocks or clusters of ...

May 23, 2015 Epithermal Gold Deposits Exploration. Many of the techniques are similar to those, have described for other deposit types. We need to start by focusing our efforts in areas where there is evidence of major felsic to intermediate volcanism, as its this volcanism that drives the epithermal systems. We also needed to find an area that has not ...

The Axi low-sulfidation LS epithermal deposit in northwestern China is the result of geological controls on hydrothermal fluid flow through strike-slip faults. Such controls occur commonly in LS epithermal deposits worldwide, but unfortunately, these have not been quantitatively analyzed to determine their spatial relationships with gold distribution and further guide mineral prospecting.
