Gold

This specimen displays specks of native gold within a milky white quartz matrix, with microcrystalline gold visible only through a microscope. The specimen originates from the Tambo Mine in Coquimbo, Chile, known for its epithermal deposits in volcanic rocks such as rhyolites and dacites. The gold in this deposit is typical of epithermal systems, where mineralization occurs at shallow depths and relatively low temperatures.

The Tambo Mine was first discovered in 1978 and commenced production in 1981. It employs both surface and underground mining techniques, with underground workings reaching depths of up to 250 meters. At its peak in 1982, the mine had the capacity to process 620 metric tons of ore daily. The El Indio-Tambo Mill is a key facility in Chile’s mining sector, contributing significantly to the region's gold production. This specimen is a fine representation of the gold-quartz association found in the region, with its unique microcrystalline formations adding to its value and scientific interest.
