Rio Tinto and Antipa Minerals have up to date the inferred mineral useful resource of the Calibre gold deposit by 62 per cent on the Citadel three way partnership (JV) venture in Western Australia.
Following drilling accomplished in 2020, the useful resource has been elevated to 2.1 million ounces of gold (beforehand 1.three million ounces) from 92 million tonnes.
