Proactive Investors - Antipa Minerals unveils 'exceptional' gold hits at Minyari project in WA's Paterson Province
By Lisa Uhlman
Antipa Minerals Ltd (ASX: AZY) has delivered more standout assay results from its 100%-owned Minyari Gold-Copper Project in Western Australia’s Paterson Province, reinforcing the deposit’s potential as both a development and discovery hub.
The latest drilling returned some of the best intersections to date, including 12 metres at 16.7 g/t gold and 0.13% copper from 143 metres down hole, with a standout 1 metre grading 176.5 g/t gold and 1% copper. Another hole cut 18 metres at 2.7 g/t gold and 0.49% copper from 275 metres, with a high-grade section of 2 metres at 17.3 g/t gold and 2.49% copper.
These results form part of Antipa’s CY2025 Phase 1 program, which has so far drilled nearly 36,000 metres across the Minyari Dome and surrounding anomalies.
Building a foundation for growth
Resource definition drilling at both the Minyari and WACA deposits has confirmed continuity of wide gold-copper zones. Highlights include:
- 31.8 metres at 1.5 g/t gold and 0.53% copper from 109.2 metres at Minyari.
- 69 metres at 0.8 g/t gold and 0.11% copper from 133 metres at WACA.
- 30 metres at 1.0 g/t gold and 0.05% copper from 232 metres at WACA.
These intersections add confidence ahead of an updated mineral resource estimate (MRE), scheduled for October, and underpin the ongoing pre-feasibility study (PFS) workstreams. Roughly 92% of PFS resource definition drilling is now complete.
Discovery potential to the north
Exploration is also unlocking significant discovery opportunities beyond the core Minyari Dome. Broad-spaced air core drilling across the Reaper-Poblano-Serrano (RPS) trend, about 30 kilometres north, has defined gold-copper anomalies stretching more than 6 kilometres. Results include 82 metres at 0.2 g/t gold from 8 metres, with higher-grade sections of 20 metres at 0.5 g/t gold.
At the nearby AL01 target, drilling has returned 8 metres at 0.4 g/t gold, including 4 metres at 0.7 g/t, with anomalies extending over 4 kilometres and remaining open in multiple directions. These areas will be followed up during the Phase 2 program, which is planned to cover 25,000–35,000 metres.
Scale and discovery upside
Antipa managing director Roger Mason said the results “serve to further highlight Minyari as a high-quality gold-copper system of scale”.
“The exceptional grades intersected at the Minyari deposit, together with the hits at WACA and GEO-01, provide a strong foundation for the upcoming Mineral Resource update and the PFS,” Mason said.
“At the same time, broad-spaced drilling at the RPS and AL01 anomalies north of Minyari point to significant discovery potential across our tenure,” he added. “This year’s programme is delivering exactly what it was designed to achieve: further advancing the development while adding new discoveries to build additional scale.”
What’s next
Assays from the final 20 Phase 1 holes are expected in October, coinciding with the release of the updated MRE. In parallel, PFS drilling and technical studies are advancing, targeting a future development decision.
Antipa already holds a 2.5-million-ounce gold resource (plus copper, silver and cobalt credits) across the Minyari Project, situated in the same region as Rio Tinto Ltd (LSE:RIO, ASX:RIO, OTC:RTNTF)–Sumitomo’s Winu and Greatland Resources Ltd (AIM:GGP, OTC:GRLGF, ASX:GGP)’s Havieron discoveries. The company says this year’s work is designed both to advance development and to build scale through new discoveries.
