• Tim's Dome identified as a priority Telfer-style reef target
• Broad gold-copper-lead-silver mineralisation intersected over 500m of strike
• Mineralisation above a large, untested airborne electromagnetic conductor

Antipa Minerals Ltd is pleased to report the second batch of assay results from Phase 1 CY2026 drilling at its 100%-owned Minyari Gold-Copper Project in Western Australia. Drilling at Tim's Dome has intersected thick gold-copper-lead-silver mineralisation over approximately 500m of strike, directly above a substantial, untested airborne electromagnetic conductor measuring approximately 1.2km long and between 200m to 470m wide. This conductor lies approximately 50m to 100m beneath the extent of current drilling and has been identified as a priority target for immediate follow-up drilling. Maximum 1m RC grades returned from drilling include 6.31 g/t gold, 1.33% copper, 1.84% lead, and 2.27 g/t silver. The presence of lead mineralisation is considered an important distal signature for intrusion-related, Telfer-style mineral systems. The oxidised and leached cap of the Telfer reef system has produced approximately 5Moz of gold via open-pit mining. Testing with diamond tails from select RC holes is scheduled to commence by mid-August.

Phase 1 CY2026 drilling results include 70 drill holes for 7,781m.

The company plans to test the large AEM target at Tim's Dome with diamond tails from select RC holes and is considering immediate follow-up infill RC drilling.
