Iron oxide copper gold (IOCG) deposits are considered to be metasomatic expressions of large crustal-scale alteration events driven by intrusive activity. The deposit type was first recognised by discovery and study of the supergiant Olympic Dam copper-gold-uranium deposit (Olympic Dam mine), and South American examples.

This samarium laser gave pulses of red light at 708.5 nm. It had to be cooled by liquid helium and so did not find practical applications. [108] [109] Another samarium-based laser became the first saturated X-ray laser operating at wavelengths shorter than 10 nanometers.
By 1880, most of the mining had shifted to lode deposits, such as the Empire Mine. Through 1959, the district produced 10.4 million troy ounces (323 tonnes) of lode gold, and 2.2 million troy ounces (68.4 tonnes) of placer gold. [18] The rich placer deposits of the Columbia Basin-Jamestown-Sonora district were found in 1853
In nickel and copper deposits, platinum-group metals occur as sulfides (e.g., (Pt,Pd)S), tellurides (e.g., PtBiTe), antimonides (PdSb), and arsenides (e.g. PtAs 2), and as end alloys with nickel or copper. Platinum arsenide, sperrylite (PtAs 2), is a major source of platinum associated with nickel ores in the Sudbury Basin deposit in Ontario ...
