Epithermal Gold Deposits Characteristics

A fascinating group and characteristic of Epithermal gold deposits is that you can virtually see them forming today, simply by visiting hot springs. Like those with Yellowstone in Wyoming or Rotorua in New Zealand. This photo is Pamukkale, low sulfidation hot springs in Turkey, with a beautiful white centre terraces.

Many epithermal deposits occur in remote regions of under-developed countries, and the construction of infrastructure, such as roads and mills, may be necessary before deposits can be mined. These expenses increase the cost of a mining operation and must be taken into consideration when calculating the economics of a deposit.
