Antipa Minerals Limited (ASX: AZY) has reported ‘outstanding’ copper-gold results from drilling at its Minyari Dome Project, with one diamond-tail doubling a previously reported intersection to 362m @ 1.4 g/t Au + 0.16% Cu from 230m downhole.
The company reports that results received to date, which account for only 30% of total metres drilled, have extended the potential size of the Minyari resource with proof that ‘significant’ zones of ‘very high‐grade’ gold‐copper‐silver‐cobalt mineralisation lie outside of the currently defined MRE boundary.
Drilling at Minyari Dome goes from strength to strength
The current drill program, which has been running since May 2021, was designed to test extensions at both the Minyari and WACA resources, which account for a combined JORC 2012 MRE of 723koz Au @ 2.0 g/t + 26kt Cu @ 0.24%.
Antipa reports that to date it has completed 27,000m of infill, step-out and brownfield drilling at Minyari Dome, with three drill rigs currently working on site. Due to the success of recently reported results, the program has been expanded to 35,000m primarily to evaluate the Minyari northwestern plunge, Minyari East, and a series of other extensional and greenfield targets.
Results have been received for 25 RC drill holes, one diamond tail and one diamond core hole for a total of 8,090m, with ‘significant high-grade’ copper-gold mineralisation encountered to the immediate east and west of the current Minyari resource.
“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 275m”
Management comments
Antipa Minerals Managing Director Roger Mason said: “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. 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 275m, and mineralisation remains open in several directions. The 2021 drill programme has been expanded to target resource extension targets, including Minyari East and a number of high priority greenfield targets all less than 3km from the existing Minyari and WACA resources. The expanded drill programme is expected to be completed in October.”
