Antipa’s Minyari Dome proves its mettle as potential open pit and underground mining operation near Telfer

New, extremely wide gold-copper intercepts from Antipa Minerals’ wholly owned Minyari Dome Project in WA’s Paterson Province sets the stage for a bigger resource and studies into a potential open pit and underground mining operation.
Further assays have been received for a diamond tail of one drill hole that more than doubles the significant gold and copper mineralisation intersected at the Minyari deposit to 362m.
Antipa Minerals (ASX:AZY) has revealed new top hits of 362m at 1.4 grams per tonne (g/t) gold and 0.16% copper from 230m, which included a previously reported intercept of 78m at 2.0g/t and 0.28% copper.
This much bigger intersection included higher grades of 47m at 2.8g/t gold and 0.22% copper from 261m, along with 20m at 5.2g/t gold and 0.40% copper, 1.2g/t silver and 0.12% cobalt from 272m and 5m at 13.0g/t gold, 0.86% copper, 2.6g/t silver and 0.3% cobalt from 277m.
Earlier results reported from this hole showed grades reaching up to 55.6g/t gold, 3.17% copper, 17.5g/t silver and 0.56% cobalt, with recent results grading up to 70.5g/t gold.
“Minyari drill hole 21MYCD0216 demonstrates the capacity of this intrusion related breccia system to generate strong gold-copper intersections over wide intervals which will support a revised resource estimate and project development studies for a potential standalone open pit and underground mining operation,” Managing Director Roger Mason said.
“At Minyari, high-grade gold ± copper mineralisation has now been intersected along 500m of strike, down to 600m below the surface and across a horizontal width of up to 290m, and mineralisation remains open in several directions.”
Drilling so far has proven that significant zones of very high-grade gold-copper-silver-cobalt mineralisation exist outside the current Minyari resource.
It has also confirmed that the high-grade mineralisation is commonly associated with sulphide matrixed breccia zones similar to Greatland Gold and Newcrest’s Mining’s (ASX:NCM) nearby 3.4Moz gold and 160,000t copper Havieron development project.
And there is still plenty of exploration upside, with the Minyari mineralisation remaining open in several directions.
The results continue to extend the potential size of the Minyari resource and enhance the project development opportunity.
This has prompted Antipa to expand its 2021 drill program to explore extension targets, including Minyari East and several high priority greenfield targets all less than 3km from the existing Minyari and WACA resources.
The two deposits currently host 723,000 ounces of gold at 2.0g/t and 26,000 tonnes of copper at 0.24%.
27,000m of infill, extensional and brownfield discovery drilling has been completed so far at Minyari Dome, with three rigs in operation and assays pending for 19,000m.
The expanded drill program is scheduled for completion in October, with a resource update expected before the end of the year.
