Epithermal vein deposit

The epithermal vein deposit (EVP) is a type of mineral deposit that forms in the shallow subsurface, typically at depths of less than 1,500 meters below the Earth's surface. These deposits are formed by hot, mineral-rich fluids that circulate through fractures and cracks in rocks. As the fluids cool, they deposit minerals, such as gold, silver, copper, lead, and zinc, into the veins. EVP are typically small in size, but they can be very high-grade, meaning that they contain a high concentration of valuable minerals.

This makes them attractive targets for mining, despite the challenges of their small size and depth.
