High-Grade Assays Confirm Polymetallic Continuity
Impact Minerals Limited (ASX:IPT) has unveiled further high-grade gold, silver, and base metals assays from its Commonwealth South prospect in New South Wales, reinforcing the potential of the Commonwealth Gold–Silver Project. The latest results come from the final two holes of a six-hole diamond drilling program funded by joint venture partner Kuniko Limited (ASX:KNI), which can earn up to 70% interest in the project.
Notably, drill hole CMKNI006 returned 7.1 metres at 8.4 g/t gold, 42 g/t silver, 1.5% zinc, and 0.7% lead from 79.9 metres, including a 3.1-metre interval grading 18.6 g/t gold and 76 g/t silver, with elevated zinc and lead. Meanwhile, CMKNI005 tested an untested induced polarisation (IP) anomaly between Commonwealth and Commonwealth South, intersecting 16 metres at 0.6 g/t gold and 804 ppm copper from 89 metres. These results confirm continuity of polymetallic mineralisation from Commonwealth to Commonwealth South at depth, a key breakthrough for the project’s scale-up potential.
Silica Hill Emerges as a Bonanza-Grade Discovery
The Silica Hill prospect, located just 200 metres west of Commonwealth South, continues to impress with bonanza-grade silver and gold mineralisation. Earlier drilling at Silica Hill included an exceptional intercept of 0.5 metres at 27 g/t gold and 20,603 g/t silver (2% Ag), highlighting its potential as a high-grade satellite deposit. Impact’s Managing Director Dr Mike Jones described the discovery as a “major breakthrough” that remains open in all directions, setting up Silica Hill as a prime target for the upcoming expanded drilling program.
This drilling success builds on Kuniko’s previous work, including a comprehensive MobileMT™ airborne geophysical survey and soil sampling that identified a 4-kilometre conductive corridor extending beyond known resources. The integration of geophysical and geochemical data with consultant Resource Potentials is expected to refine new drill targets across the broader project area, including promising results from nearby Gladstone West and Geenobby prospects.
Phase 2 Drilling Program Scheduled for July
Following the successful completion of Phase 1, Kuniko has secured a diamond drill rig and plans to commence a more extensive Phase 2 drilling campaign in early July. The program will focus on step-out extensions, higher-grade zones at depth, and further testing of Silica Hill’s newly identified mineralisation. This expansion aims to build on the current JORC (2012) Inferred Mineral Resources at Commonwealth and Silica Hill, which total approximately 88,800 ounces of gold and 3.3 million ounces of silver, including significant zinc and lead credits.
Impact retains a 30% free-carried interest until a decision to mine, providing leverage to exploration success without immediate capital commitment. Under the earn-in agreement, Kuniko can increase its stake to 51% by spending $1.5 million within two years, and up to 70% with an additional $1.5 million over the following two years. This structure aligns funding with exploration milestones, maintaining Impact’s exposure to potential upside while mitigating near-term dilution.
These developments follow earlier confirmation of high-grade massive sulphides at Commonwealth, which set the tone for the current drilling program and the anticipated Phase 2 expansion high-grade massive sulphide mineralisation. The project’s geological similarities to the world-class Eskay Creek deposit in British Columbia add a compelling dimension to its exploration narrative.
Bottom Line?
The upcoming Phase 2 drilling will be pivotal in defining the scale and grade continuity of this polymetallic system, with Silica Hill’s bonanza intercepts demanding close attention.
Questions in the middle?
- Will Phase 2 drilling confirm the extent of the bonanza-grade Silica Hill mineralisation?
- How might deeper copper-gold porphyry targets influence the project’s valuation?
- What impact will commodity price fluctuations have on the joint venture’s development timeline?
