Gold deposited in structures formed during mountain building — the style behind most of Canada's and Australia's historic gold camps.
Gold deposits formed during mountain-building (orogenic) events, typically hosted in quartz veins within metamorphic rocks. Orogenic gold deposits are found in greenstone belts worldwide and include many historic gold mining districts.
Orogenic systems are the classic underground gold mine: narrow, high grade, and persistent to great depth. Many have produced for decades, which makes brownfield ground around old camps consistently attractive.
