Significant resource upside for Antipa at Minyari with fresh thick, high-grade gold intercepts
The steady stream of drill results being rolled out from Antipa’s 100% owned Minyari Dome Project in WA’s Paterson Province continues to demonstrate the potential large scale of the discovery.
The latest results from drilling at Antipa Minerals’ (ASX:AZY) Minyari and WACA deposits has again shown thick, high-grade, near-surface gold and copper ± cobalt and silver, providing a strong foundation for a significant resource upgrade.
A further fifty drill hole results showed notable near-surface intercepts such as 35m at 3.52 grams per tonne (g/t) gold and 0.48% copper from 20m, which included higher grade sections of 1m at 22.0g/t gold, 0.31% copper and 0.09% cobalt from 41m, and 1m at 25.1g/t gold and 0.58% copper from 48m at the Minyari deposit.
Meanwhile, drilling at depth at Minyari returned a whopping 207m at 1.45g/t gold and 0.09% copper from 219m, including a high-grade intercept of 5m at 36.84g/t gold, 1.94% copper, 10.1g/t silver and 0.11% cobalt from 419m, and 11m at 4.95g/t gold, 0.14% copper, and 0.07% cobalt from 303m.
This was accompanied by 142m at 1.87g/t gold and 0.16% copper from 294m, including 14m at 10.60g/t gold, 0.79% copper, 2.0g/t silver and 0.03% cobalt from 410m.
At the WACA deposit, notable intercepts included 47m at 1.95g/t gold and 0.33% copper from 151m, including 22m at 2.84g/t gold and 0.55% copper and 2m at 6.55g/t gold and 2.19% copper from 169m.
Also at WACA was a hit of 31m at 2.24g/t gold and 0.22% copper from 18m, including 13m at 4.25g/t gold and 0.35% copper from 23m.
“These results continue to highlight the development opportunity demonstrating the potential for significant resource upside and extend the thick high-grade breccia style mineralisation at depth at both Minyari and WACA,” Managing Director Roger Mason said.
“At Minyari two high-grade 270 to 300 gram-metre gold downhole intersections are particularly impressive, whilst at WACA several shallow, high-grade 50 to 100 gram-metre gold downhole intersections were highly encouraging, including an intersection in the southern area of WACA which identified a thick high-grade ore shoot.
“The company eagerly awaits the remaining assays, in particular for the deeper holes into the down-plunge target at Minyari and also for the greenfield discovery focused holes which provided significant visual encouragement, including at Minyari North.”
At Minyari, high-grade gold with copper, silver and cobalt mineralisation extends for 500m of strike across a width of up to 300m and now runs down to 670m below the surface.
The high-grade mineralisation at WACA extends for 650m of strike, spanning a width of up to 100m and has now been extended down to 510m.
Mineralisation remains open in several directions at both deposits.
Results have now been received for 90% of the Minyari-WACA 2021 resource infill and resource extensional drilling program, continuing to increase the potential size of the Minyari and WACA resources and enhance the project development opportunity.
The drilling results received so far have substantially extended the zones of very high-grade gold-copper-silver-cobalt mineralisation outside the current Minyari and WACA resources.
Antipa expects this to have a material positive impact on the existing Minyari-WACA 2017 resource, which currently totals 723,000 ounces of gold at 2.0g/t and 26,000 tonnes of copper at 0.24%.
A resource update is slated for release in the first quarter of 2022.
Late last year, Antipa revealed the ‘camp-style’ gold-copper potential of its 100% owned Minyari Dome Project right next door to Newcrest Mining’s (ASX:NCM) massive Telfer gold-copper-silver mine and processing facility.
A reference to ‘camp-style’ potential indicates the possible significant scale of a project, with these multiple near-surface discoveries remaining open.
Drilling at depth at Minyari has confirmed the continuity of moderate northwest plunging “pipe” like, thick high-grade breccia mineralisation, which remains open at depth.
With this continued exploration success at Minyari Dome, the project has shown potential to be both an open pit and underground mining operation.
