Proactive Investors - Antipa Minerals strengthens Minyari Dome growth case with more high-grade hits

By Lisa Uhlman

Antipa Minerals Ltd (ASX: AZY) has delivered another strong batch of drill results from its Minyari Dome Gold-Copper Project in WA’s Paterson Province, intersecting high-grade zones at both Fiama and Minyari and further expanding the scale of its 100%-owned resource footprint.

The latest results include a standout 53 metres at 1.9 g/t gold from 233 metres at the Fiama prospect, with internal hits up to 32.6 g/t gold. At Minyari, drilling returned multiple high-grade zones at depth, including 28 metres at 1.9 g/t gold and 0.17% copper from 392 metres and a separate interval grading up to 33.1 g/t gold with copper and silver credits.

Managing director Roger Mason said the results continue to validate Antipa’s thesis that Minyari Dome has substantial growth ahead.

“These latest results, particularly from Fiama and at the Minyari deposit, further highlight the strong growth potential within the broader Minyari Dome system, with several very high-grade gold intersections returned in this batch of assays, including a 422 g/t gold hit,” Mason said. “With a high-impact phase of new-discovery drilling ongoing and key PFS workstreams continuing at pace, we are set for an exciting finish to the year.”

High-grade intersections drive resource expansion

The sixth batch of assays from Antipa’s CY2025 program confirms that mineralisation at Fiama and Minyari continues to extend down-dip and along strike. Key highlights include:

Fiama (growth drilling):

• 53m at 1.9 g/t gold and 0.08% copper from 233m, including 7m at 6.5 g/t gold from 274m and 1m at 32.6 g/t gold and 0.24% copper from 279m

• 7m at 2.1 g/t gold and 0.24% copper from 107m

Minyari (growth drilling):

• 28m at 1.9 g/t gold and 0.17% copper from 392m

• 8.3m at 9.0 g/t gold and 0.57% copper from 584.8m, including 2.2m at 33.1 g/t gold

Results from Minyari South also confirmed shallow extensions, with 18m at 1.0 g/t gold from 50m.

New discovery drilling adds momentum

Alongside resource growth drilling, Antipa continues to pursue new discoveries across the broader Minyari Dome system.

Phase 2 discovery drilling has now completed 290 holes for 23,265 metres, with assays returned for 7,694 metres so far.

Notable new-zone intersections include:

• 8m at 4.4 g/t gold from 172m

• 4m at 2.1 g/t gold and 0.09% copper from 90m

These results highlight potential for a maiden resource south of Fiama and Rizzo.

Pre-feasibility study drilling reinforces continuity

Drilling linked to the pre-feasibility study (PFS) has confirmed structural and grade continuity across the Minyari system.

One PFS-focused hole returned the highest-grade gold intersection ever recorded at Minyari:

• 0.13m at 422 g/t gold, 13.40% copper and 39.8 g/t silver within a broader intersection of 44m at 2.3 g/t gold from 489m

Resource definition drilling is now complete, while sterilisation drilling has identified additional near-surface mineralisation in areas previously earmarked for infrastructure.

Next steps

The Phase 2 program — targeting 25,000–35,000 metres — is scheduled for completion by mid-December, with more assay batches due in the coming weeks. An updated mineral resource estimate for Minyari Dome is on track for Q4 CY2025, alongside continued PFS work on hydrology, geotechnical and metallurgical testing.

Antipa controls more than 4,100 square kilometres in the Paterson Province and hosts existing resources of 2.5 million ounces (Moz) gold, 84,000 tonnes of copper, 666,000oz silver and 13,000 tonnes of cobalt. Minyari Dome currently stands at 2.4Moz gold at 1.5 g/t, and Antipa is aiming to grow this further ahead of development studies.

With multiple high-grade hits, ongoing discovery drilling and PFS de-risking, Antipa has positioned Minyari Dome as one of the most advanced gold-copper growth opportunities in the Paterson region.
