Trunkey Creek

The Trunkey Creek Project (EL5748), covering 59.7 km², is located around the township of Trunkey, approximately 38 km southwest of Bathurst in New South Wales. Accessible via bitumen and dirt roads, the area has a historical gold mining legacy dating back to 1851, with notable activity between 1852–1880 and 1887–1908. By 1873, the region supported a population of 2,500, reflecting its importance during the gold rush era.

Gold mineralisation extends across a 5.5 km-long and 250–500 m-wide mineral field, with hard rock workings striking north in bedding and cleavage-parallel structures. Sub-parallel quartz reefs, spaced 30–50 m apart over a 2 km strike, host gold associated with pyrite, arsenopyrite, and galena. Historical grades ranged from 12–20 g/t Au, with some deeper zones yielding up to 3 oz/t.

Geophysical surveys have identified six high-priority induced polarisation (IP) targets for drilling. Strong chargeability and resistivity anomalies, particularly near the township and at the southern and northwestern boundaries, align with historical workings and resistivity trends. These anomalies likely correlate with silica-rich veins and sulphide-associated gold mineralisation, highlighting the project’s exploration potential.
