Antipa Extends Tim's Dome Gold-Copper Strike to 2.2km

Antipa Minerals has expanded the mineralized footprint at its Tim’s Dome project in Western Australia to approximately 2.2 kilometers of strike. The company’s latest drilling program, part of its wholly owned Minyari gold-copper asset, outlines gold-copper-lead-silver mineralization across this extended zone.

The update follows a fourth batch of results from 13 reverse circulation (RC) holes totaling 3,073 meters. Antipa is now shifting to diamond core drilling from surface to test a large, untested airborne electromagnetic (AEM) conductor estimated to lie 270 to 340 meters below the ground surface.

Drilling tests deep conductor target

Six holes in the recent batch tested ground above or adjacent to the AEM conductor, which remains the key exploration target. Previous attempts to intersect the conductor by extending RC holes with diamond tails were unsuccessful, prompting the operational shift to surface diamond drilling. The conductor is estimated to be between 200 and 470 meters wide.

Managing Director Roger Mason stated that mineralization and strong pathfinder anomalies continue to appear immediately above and adjacent to this conductor. Antipa is investigating whether the surrounding mineralization forms part of a Telfer-style reef system, a hypothesis that requires direct testing of the conductor’s contents.

Intersections show high-grade potential

Specific holes returned significant grades, including hole 26XTDC0068 with 30 meters at 0.5 grams per tonne gold from 180 meters, including 3 meters at 1.7 grams per tonne. Hole 26XTDC0078 yielded 26 meters at 0.4 grams per tonne gold and 0.23 percent copper from 214 meters, with a higher-grade section of 7 meters at 1.2 grams per tonne gold and 0.28 percent copper.

A shallower intersection in hole 26XTDC0072 returned 3 meters at 2.9 grams per tonne gold from 16 meters, including 1 meter at 8.1 grams per tonne. Across the batch, maximum one-meter grades reached 8.11 grams per tonne gold, 0.65 percent copper, 0.54 percent lead, and 2.08 grams per tonne silver.

Resource expansion near Telfer mine

Tim’s Dome hosts a 110,000-ounce gold mineral resource and is located approximately 11 kilometers from Greatland Resources’ Telfer mine. Antipa noted that new reef-style intersections are located 50 to 130 meters from the existing resource, suggesting potential for resource growth.

Two rigs remain active across Tim’s Dome and Minyari Dome. Antipa has completed 314 holes for 37,225 meters in its phase one 2026 program, with further assays expected to follow. The company emphasizes that reported intersections are down-hole lengths, and true widths remain uncertain.
