• Maiden aircore drilling program at Mt McKenna Project defines multiple mineralised trends, including a 1.5km mineralised structure
• Additional 250m strike length of elevated arsenic values up to 1,750ppm, coincident with anomalous gold values
• Reverse Circulation (RC) drilling planned to assess the gold potential of the newly identified structures at depth

Platina Resources Limited has identified a number of new gold targets in the maiden aircore drilling program at its Mt McKenna Project in Western Australia, including a 1.5km mineralised structure and a second continuous structure of 250m strike length with elevated arsenic values up to 1,750ppm. The Phase 1 aircore drilling program was designed to delineate gold mineralisation concealed beneath a thin layer of transported cover, with a total of 126 aircore holes for 6,056m drilled across the northern portion of the Target 2 area. The drilling defined multiple mineralised trends, with the majority of aircore holes along the 1.5km mineralised structure ending in gold mineralisation. The 1.5km mineralised structure is defined by intersections including 1m @ 0.64g/t Au, 4m @ 0.24g/t Au, 3m @ 0.27g/t Au, 4m @ 0.12g/t Au, and 3m @ 0.13g/t Au. Additional anomalous intercepts include 11m @ 0.36g/t Au and 4m @ 0.20g/t Au. The strong arsenic anomaly coincident with anomalous gold values at the end of one hole lies immediately south of a known area hosting gold nuggets and remains completely open to the south. Reverse Circulation (RC) drilling is now required to assess the gold potential of these newly identified structures at depth. Exploration and cultural heritage clearances across Targets 4 and 5 will commence in February, enabling the generation of new aircore drilling targets, with the aim of developing multiple prospects for subsequent deeper RC drilling.

The next phase of drilling requires either RC and/or slimline RC drilling using an aircore rig, aimed at infilling and deeper testing the 1.5 km mineralised trend. Potential southern and down-dip extensions of the arsenic anomaly zone will also be evaluated through this deeper drilling. In parallel, a ground gravity survey will commence in February 2026 across the southern portion of the project area, covering Targets 4 and 5. Newly generated aircore targets at Targets 4 and 5, together with currently identified targets at Target 2, will then be tested by deeper drilling as part of a single, integrated reverse circulation drill program.
