Proactive Investors - Antipa Minerals hits high-grade gold at Minella as Minyari Dome resource growth continues

By Lisa Uhlman

Antipa Minerals Ltd (ASX: AZY) has reported more strong assay results from its 100%-owned Minyari Gold-Copper Project in Western Australia’s Paterson Province, highlighting high-grade gold intersections at the Minella prospect that reinforce the potential for further resource growth within the broader Minyari Dome system.

The latest results come from the company’s CY2025 Phase 1 drilling program, with all 305 holes (35,158 metres) now complete. Assays for 12,097 metres of the 18,340-metre resource definition component have been received, while Phase 2 discovery drilling remains in progress.

High-grade intercepts strengthen Minella potential

At Minella, standout results included 67 metres at 1.1 g/t gold and 0.33% copper from 159 metres, featuring 23 metres at 2.4 g/t gold and 0.65% copper from 200 metres, and a higher-grade core of 2 metres at 9.8 g/t gold and 0.87% copper.

Additional results from nearby prospects also confirmed mineralisation extensions:

• 27 metres at 0.8 g/t gold and 0.05% copper at GEO-01 Central, including 1 metre at 5.8 g/t gold; and

• 31 metres at 0.7 g/t gold and 0.10% copper at Minyari South, including 1 metre at 7.7 g/t gold.

Managing director Roger Mason said the Minella results demonstrated “the strength of the Minyari system and the growth potential that exists immediately adjacent to the planned Minyari open pits”.

“The strong gold and copper grades intersected here reinforce the resource expansion potential within close proximity to the proposed development footprint,” he said. “When combined with the latest results from GEO-01 and Minyari South, we have confidence in the geology’s capacity for additional and sustained resource growth.”

Exploration momentum builds across the dome

Air-core drilling along the Reaper-Poblano-Serrano (RPS) trend, about 30 kilometres north of Minyari, also returned encouraging results — including 36 metres at 0.5 g/t gold and 326 parts per million (ppm) copper from 68 metres — extending a 2-kilometre anomaly open in both directions.

In parallel, resource definition drilling at Minyari continued to confirm strong continuity of mineralisation, such as 5 metres at 2.6 g/t gold and 0.10% copper from 679 metres, including 0.4 metres at 29.7 g/t gold.

Next steps

Remaining assay results from both the resource definition and discovery-focused programs are expected in the coming months, with Phase 2 drilling on track for completion by mid-December.

Antipa will update its Mineral Resource Estimate later this month, while pre-feasibility workstreams — including geotechnical, metallurgical and hydrogeological studies — continue to advance as the company refines its standalone gold-copper development strategy at Minyari Dome.
