Hog Ranch is comprised of 347 unpatented mining claims on Federal land for a total area of approximately 2,800 hectares (6,919 acres). Hog Ranch contains both oxide and sulphide mineralization. The oxide horizon makes up the majority (approx. 93%) of the Mineral Resource. Rex Minerals is exploring two key targets at Hog Ranch: Krista, and the current focus, Bells.
Gold was first discovered at Hog Ranch in 1980 as part of a Joint Venture between Noranda Exploration and Ferret Exploration. Exploration and economic analysis by Ferret Exploration, a consortium made up of Western Goldfields, Geomax and Royal Resources, began mining in 1986 via open pit and heap leach method.
At the end of 1992, the gold price had fallen to US$333 per ounce and mining was terminated.In August 2019, Rex Minerals purchased a 100% interest in Hog Ranch via its purchase of the private company Hog Ranch Group, which in turn has 100% ownership of the company Hog Ranch Minerals Inc.
Subsequent exploration by Rex Minerals has increased the Maiden Mineral Resource reported in September 2019 by 69%.
