Antipa Minerals Ltd (ASX:AZY) has delivered a string of new gold and copper discoveries from the final batch of CY2025 drilling at its 100%-owned Minyari Gold-Copper Project in Western Australia’s Paterson Province, reinforcing the scale and growth potential of the broader Minyari development footprint.
Plan showing location of Antipa's 100%-owned, 4,500km2 Minyari Project: Plan includes Greatland Resources’ Telfer Mine, Havieron development project and O’Callaghans deposit, Rio Tinto-Sumitomo’s Winu deposit, Rio Tinto’s Calibre-Magnum deposits, and Cyprium’s Nifty Mine.
The eighth and final batch of results includes a newly identified high-grade gold lode at Fiama close to surface, confirmation of a large-scale northern repeat structure beneath the Minyari Dome, thick gold-copper intersections at Reaper–Poblano–Serrano (RPS), and a new copper discovery at Yolanda.
“The final batch of CY2025 results are a tremendous way to wrap up last year’s drilling program, delivering multiple new gold discoveries in close proximity to our planned Minyari development,” Antipa managing director Roger Mason said. “This reinforces the opportunity we have to materially grow the Mineral Resource base around future planned infrastructure.”

Note the gold-copper discovery intersections across a large area (700m by 500m) indicating that Rizzo and Fiama may be connected and extending mineralisation 500m to the south into an area which Antipa’s access to was previously prevented by the Paterson IGO Farm-in Project (tenement) boundary.
New high-grade lode at Fiama
One of the standout outcomes was the discovery of a new high-grade lode just 65 metres north of the existing Fiama resource.
Drilling returned 24.7 metres at 1.4 g/t gold and 0.07% copper from 39.3 metres, including 2.3 metres at 6.8 g/t gold and 0.18% copper, with mineralisation remaining open in all directions.
Long Section from south of Fiama to Minyari North: Including the Minyari, WACA, Minyari South, Minyari Southeast and GEO-01 area (i.e. Main Zone, Fiama, Minella and Central) deposits and recently discovered southern extensions south of Rizz0 and Fiama, showing gold drill intercepts. Highlights multiple zones of plunging gold-copper resources and mineralisation variously open down dip/plunge from depths below the surface as shallow as 40m to 650m. Note this highly prospective 3.6km trend extends to approximately 5.0km to the Judes copper-silver-gold deposit to the north.
The lode sits only 32 metres below surface and supports further near-term resource growth adjacent to the Fiama deposit. Follow-up drilling is planned for the June 2026 quarter to extend and delineate the new gold-copper zone.
High-grade re-splits south of Rizzo–Fiama further highlighted near-surface potential, including 1 metre at 39.8 g/t gold from 46 metres, confirming the presence of very strong gold mineralisation.

Multiple zones of mineralisation remain open, including high-grade, with highly prospective Fiama-Rizzo folded dolerite and meta-sediment strike length 500 to 800m, and an across-strike width of 120 to 160m.
Northern repeat confirms large-scale target
At the Minyari Northern Repeat target, diamond drilling intersected significant gold-copper mineralisation around 250 metres north of the existing Minyari Dome deposit and about 500 metres below surface.
Key results included 12.2 metres at 1.2 g/t gold and 0.04% copper from 623 metres, including 7.2 metres at 2.0 g/t gold and 0.06% copper.
The hole successfully intersected prospective Sundown host rocks within a favourable structural setting, confirming what Antipa describes as a new large-scale, high-impact target zone with potential to host Minyari-style mineralisation.

This hole successfully located the prospective Sundown host rocks coincident with an antiformal cross fold axis structural domain, confirming a new large-scale high-impact target zone.
RPS shaping as maiden resource opportunity
Further drilling at the Reaper–Poblano–Serrano (RPS) discovery continued to deliver thick, shallow gold-copper intersections beneath minimal cover.
Notable results included 146 metres at 0.3 g/t gold and 0.07% copper from 94 metres, with higher-grade internal zones, and 100 metres at 0.3 g/t gold and 0.03% copper from 96 metres.
The latest results extended mineralisation at Serrano to an 800-metre strike length and at Poblano to 330 metres, strengthening RPS as a potential maiden resource opportunity. Additional drilling is planned in CY2026 to further define the system.

Note the 2km long by up to 300m wide Poblano-Serrano gold-copper-bismuth anomaly which remains open along strike. Mineralisation is hosted by siliceous metasediments with lesser meta-dolerite beneath shallow cover (15 to 20m).
New copper discovery at Yolanda
Antipa also confirmed a new copper discovery at the Yolanda target, located 1 kilometre west of the WACA deposit, where reconnaissance RC drilling defined a 1.2-kilometre-long copper anomaly beneath shallow cover.
Drilling intersected 44 metres at 0.07% copper from 40 metres to end of hole, including 12 metres at 0.13% copper, with additional copper hits along strike confirming a broad, open trend.
Yolanda is interpreted to be hosted within Puntapunta Formation rocks, which host major Paterson Province deposits including Greatland Resources’ Havieron and Rio Tinto–Sumitomo’s Winu. Follow-up air core and reverse circulation drilling is planned in the first half of CY2026.

Note the 1.2km long by 220m wide Yolanda copper anomaly, which is open in several directions, confirming a new large-scale highly prospective trend. Multiple prospective regions of the Yolanda AEM conductivity anomaly are present along a strike length of approximately 6km and remain almost completed untested by drilling. Mineralisation is hosted by Puntapunta Formation metasediments beneath shallow cover (4 to 10m).
Resource update and next steps
All CY2025 drilling results are now being incorporated into an updated Mineral Resource Estimate, scheduled for completion in February 2026. This update will underpin the Minyari pre-feasibility study ore reserve, alongside ongoing technical, permitting and development workstreams.
With field activities set to recommence this quarter, Antipa is positioning CY2026 as another active year for discovery and resource growth across its 4,500-square-kilometre Minyari landholding.
