Highlights

  • December 2025 start for Mt Boppy and Pipeline Ridge drilling programs.
  • Mt Boppy targets deep gold extensions and structural repeats of known mineralisation.
  • Pipeline Ridge shallow program aims to define oxide gold zones near surface.

Manuka Resources Limited (ASX:MKR) has announced that its gold exploration drilling program across the Cobar Basin will commence in the first week of December 2025. The program will focus on the Mt Boppy Gold Mine and the Pipeline Ridge gold prospects, both located within the company’s broader Cobar Basin project area in New South Wales.

The company stated that the upcoming exploration marks a key step in its efforts to expand and extend its current 10-year Cobar Basin production plan.

Deep Drilling to Test Extensions

At the Mt Boppy Gold Mine, which historically produced around 500,000 ounces of gold averaging approximately 15 g/t Au, the upcoming drilling will test for deep extensions and potential new discoveries.

The initial phase will include three drill holes reaching depths of around 500m, targeting both the known mineralised structure and a new structural feature located about 1,000m south of the main deposit. Historical data and geophysical analysis have indicated that Mt Boppy remains open along strike and at depth.

The geology at Mt Boppy is characterised by silica-dominated veining and brecciation, consistent with a high-level hydrothermal system. The upcoming exploration integrates previous drilling results with airborne and surface geophysical data to refine targets within the structurally complex Cobar Basin setting.

Pipeline Ridge: Shallow Gold Targets Near Surface

Located approximately 28km south of Mt Boppy, the Pipeline Ridge prospect hosts volcanic massive sulphide (VMS)-style mineralisation. Historic drilling has identified shallow gold mineralisation close to surface, with intersections extending down to depths exceeding 150m.

The Phase 1 program at Pipeline Ridge will comprise approximately 3,165m of shallow drilling, with holes up to 60m deep. This campaign aims to evaluate the previously defined exploration target ranging between 187kt and 365kt at grades between 1.1 g/t Au and 1.5 g/t Au.

Two main mineralised zones have been outlined—spanning 295m and 180m respectively—within a broader 1,000m strike length. Phase 2 drilling is expected to follow, testing deeper mineralisation beneath the oxide gold zones.
