Near-surface anomalous copper mineralisation has been intersected, as have near-surface, thick intervals of anomalous nickel mineralisation.

Two drill holes targeted the broader copper-in-soil anomaly and one hole tested the geology of the Tirosa basin. The remainder of the basin, large parts of the copper-in-soil anomaly and the nickel-in-soil anomalies are yet to be tested.

The project is under agreement with First Quantum Minerals (FQM), which is managing the exploration on the project during its due diligence period.

Mukai lies adjacent to FQM’s Trident project.

“The cost-effective surface sampling undertaken by Tertiary in 2023, along with its spatial position near to FQM’s Trident project, confirmed the Mukai project as a high priority drill target for FQM.

“The three drill holes targeted the broader copper-in-soil anomaly and intersected both near surface anomalous copper and nickel mineralisation. Two of the holes collared on the basin margin within the Lower Roan Subgroup siliclastic sediments and the footwall to the target units. The third hole was collared within the basin and in the hanging wall and drilled through the Upper Roan to Lower Roan (footwall) geology,” Tertiary MD Richard Belcher explains.

“Given the limited drilling completed to date, and with only one hole testing the target units and much of the soil anomaly untested, we believe there is still much potential upside to this project,” he highlights.

Tertiary is liaising with FQM on the next steps for exploration. “FQM has reported that the drilling and other preparatory work completed reaches their minimum expenditure of $500 000 for year one as part of the 24-month due diligence period,” Belcher informs.
