Orogenic gold ores are associated with regionally metamorphosed terranes of all ages (Kerrich and Cassidy, 1994) and are spatially linked to subduction-related thermal processes (Kerrich and Wyman, 1990) (Fig. 1).

Orogenic gold deposits are comprised of complex quartz vein arrays that form as a result of fluid flow along transcrustal fault zones in active orogenic belts.

Orogenic gold deposits (Böhlke, 1982) dominantly form in metamorphic rocks in the mid- to shallow crust (5–15 km depth), at or above the brittle-ductile transition, in …

Orogenic gold deposits (Böhlke, 1982) dominantly form in metamorphic rocks in the mid- to shallow crust (5–15 km depth), at or above the brittle-ductile transition, in compressional settings that facilitate transfer of hot gold-bearing fluids from deeper levels (Goldfarb et al., 2005; Groves et al., 1998; Phillips and Powell, 2009).

Ore Processing: Once gold-bearing ore is extracted from the ground, it is usually processed to extract the gold particles. Ore processing methods can vary depending on the type of gold deposit, but commonly include crushing, grinding, gravity separation, flotation, and …

Concept-based orogenic gold exploration requires a scale-integrated approach using a robust mineral system model. Most genetic hypotheses for orogenic gold deposits that involve near-surface or magmatic-hydrothermal fluids are now negated in terms of a global mineral system model.

Gold occurs in a wide range of deposit types and settings, but this paper is concerned with deposits in which gold forms the main economic commodity or a co-product. Deposits in which gold occurs only as a by-product are not considered, including IOCG deposits.
