Antipa Minerals Ltd (ASX AZY) has announced a 19% increase in the inferred gold mineral resource estimate for the Calibre deposit within the Citadel Joint Venture Project, in partnership with Rio Tinto Exploration in Western Australia. Proactive’s Tylah Tully brings you just the facts.
The updated mineral resource estimate now totals 111 million tonnes at 0.86 grams per ton gold-equivalent, containing 3.1 million gold-equivalent ounces. This includes 2.5 million ounces of gold, 115,000 tonnes of copper, and 1.6 million ounces of silver, based on a 0.4 grams per tonne gold-equivalent cut-off grade.
The Calibre resource, which extends for approximately 1.4 kilometres and remains open along strike to the south, is situated 45 kilometres east of Rio Tinto’s Winu resource, which contains 7.9 million ounces of gold.
Antipa Minerals emphasised that the update confirms Calibre as a large-scale gold-copper-silver mineral system with significant growth potential. The company also suggested that, given its scale and metallurgical characteristics, Calibre could be suitable for a large-scale open-pit mining development scenario.
Antipa’s Managing Director, Roger Mason, said: “This update reaffirms that Calibre, which was discovered by Antipa, is a very large-scale gold-copper-silver mineral system with significant growth potential located in the rapidly advancing tier-one Paterson Province.
“The scale of the Calibre deposit in conjunction with its off-the-shelf metallurgical characteristics and shallow, predominantly free-digging, post-mineralisation cover, should suit a potential large scale open pit mining development scenario.”
