Antipa Minerals has extended the scale and upside of its Minyari gold-copper project in Western Australia, growing the resource to 3.6 million ounces (Moz) gold equivalent and launching a major new drilling campaign to drive further discoveries.

In total, the miner has completed its 2025 calendar year drilling program, with the eighth and final batch of results confirming additional resource growth opportunities and broader project-scale discovery upside.

Likewise, Antipa increased its total mineral resource estimate (MRE), including satellite deposits, to 69 million tonnes (Mt) at 1.33 grams per tonne (g/t) gold, containing 2.9 million ounces (Moz) of gold, or 3.6Moz at 1.62g/t of gold equivalent.

The miner said that during the quarter it continued to advance its Minyari gold-copper project in Western Australia’s Paterson Province, with a focus on progressing pre-feasibility study (PFS) workstreams.

For the Fiama site, a new high-grade lode returned findings of 27.4m at 1.4g/t gold, and 0.04 copper from 39.3m.

This includes 2.3m at 6.8g/t gold and 0.18 per cent copper from 39.3m, with the lode remaining open in all directions.

As for Minyari Northern Repeat, drilling was completed 250m north of the Minyari deposit, returning 12.2 metres at 1.2g/t gold and 0.04 per cent copper, from 623m.

This also includes 7.2m at 2g/t gold and 0.06 per cent copper from 628 metres, confirming a new large-scale high-impact target zone.

At Yolanda, located approximately 1km west of the WACA deposit, Antipa intersected 44m at 0.07 per cent copper from 40m to end-of-hole, including 12m at 0.13 per cent copper, defining a 1.2km anomalous copper trend.

In addition, high-grade re-splits from the south of Rizzo-Fiama returned 1m at 39.8g/t gold from 46m, while drilling at the Reaper-Poblano-Serrano (RPS) corridor delivered broad, shallow gold-copper intersections, including 146m at 0.3g/t gold and 0.07 per cent copper.

After the quarter, the updated MRE for the Minyari project reinforces a standalone, scalable open-pit and underground development opportunity.

The Minyari Dome component alone now hosts 2.5Moz of gold, accounting for the majority of the project’s resource base.

The company also reported that 85 per cent of this resource is now classified in the higher-confidence indicated category, supporting ongoing study work.

Antipa said it made substantial progress across key PFS-related technical, environmental, regulatory, native title and commercial workstreams during the quarter, with the study remaining on track for completion in the third quarter of 2026.

Metallurgical testwork is largely complete, confirming the ore is free milling and suitable for conventional carbon-in-leach processing, with gold recoveries ranging from 89–98 per cent.

Looking ahead, the company has commenced a major new drilling campaign across the Minyari project, comprising 321 holes for approximately 41,000m.

The program is designed to both expand existing resources at Minyari Dome and test high-priority regional greenfield targets across Antipa’s 4500 square kilometres landholding in the Paterson Province.

At the end of the quarter, Antipa held a cash balance of approximately $47.7 million, positioning the company to fund ongoing exploration and development activities.
