Epithermal deposits are a type of lode deposit. They contain economic concentrations from a precious metal such as gold and silver, and in some cases base metals such as copper, lead, iron ore and zinc.
Like other lode deposits, the minerals in epithermal deposits can be disseminated throughout the orebody, though more often they are contained in a network of veins. Aside from epithermal deposits, classic examples of lode gold deposits include VMS deposits and Carlin-type deposits.
Gold is often the dominant metal in epithermal deposits, and for that reason epithermal gold deposits are a key point of interest when discussing epithermal deposits. Read on for a brief overview of epithermal gold deposits, from how they form to what the different types are. These deposits can be very desirable to mining and exploration companies, and it’s worth being aware of what makes them so alluring.
