Antipa’s CY2025, two-phase exploration drilling campaign included a total of 615 holes for approximately 62,000m. The programme had a dual purpose: to grow the existing Mineral Resource at Minyari Dome and test greenfield targets to deliver new discoveries across the broader 4,500km2 Minyari Project.

Antipa’s CY2025, two-phase exploration drilling campaign included a total of 615 holes for approximately 62,000m. The programme had a dual purpose: to grow the existing Mineral Resource at Minyari Dome and test greenfield targets to deliver new discoveries across the broader 4,500km2 Minyari Project.

GROWTH DRILLING PROGRAMME

The growth drilling component of the programme was designed to expand the existing near-surface Minyari Dome Mineral Resource. 

Drilling spanned the Minyari Dome Deposit Area, particularly Minyari South and the main Minyari deposit, and the GEO-01 Deposit Area, including the Main Zone, Minella, and Fiama gold-copper deposits. All of these deposits currently remain open down-dip and in some cases along strike.

DISCOVERY DRILLING PROGRAMME 

The discovery drilling portion of the programme was designed to test greenfield targets to deliver new discoveries across the broader 4,500km2 Minyari Project area. A summary of some of the key target areas is provided below.

Tim’s Dome Deposit Area

Tim’s Dome is situated 10km northwest along strike from Greatland’s Telfer mine. The geology is analogous to the Telfer deposit host stratigraphy, set between surface and less than nine metres of sand cover. CY2025 results were encouraging, expanding the gold mineralisation to a strike length of 3.5 kilometres by between 300 and 600 metres across strike. Multiple new gold-targets have been identified on the eastern limb of Tim’s Dome, which remain open in all directions (in part due to the broad spaced nature of drilling).

GEO-01 Deposit Area - Fiama

Located approximately 330m southeast of the GEO-01 Main Zone, Fiama features shallow gold ± copper mineralisation extending along a 300m of strike length, up to 120m across strike.

Fiama growth drilling successfully extended mineralisation down dip and included a 100 gold-gram-metre intersection in RC drill hole 25MYC0873.

Reaper-Poblano-Serrano (RPS) Trend

The RPS Trend lies 30km north of Minyari, it currently extends for approximately 2,000 metres along strike and up to 250 metres across strike and remains open in both directions along strike and down dip.

Results returned from Poblano show significant ore grade gold-copper mineralisation with a reduced intrusion related mineral system signature that includes associated bismuth-tungsten±molybdenum across a 300 by 300 metre area. This mineralisation, which includes shallow to moderate southwest plunging high-grade zones, appears to be annular to the magnetic anomaly, suggesting possible Havieron deposit style affinities.

GEO-01 Deposit Area - Rizzo

Drilling at Rizzo followed up a previous air core target in an area which Antipa’s access to was previously prevented by the Paterson IGO Farm-in Project (tenement) boundary. Notable results included from CY2025 included 21m at 1.8 g/t gold and 0.06% copper from 44m.
