Duketon Mining (ASX:DKM) reports ‘significant’ shallow PGE assays following reverse circulation (RC) drilling at its 100% owned Rosie Ni-Cu-PGE deposit, as part of its Duketon Project in Western Australia.
The results, generated by four drill traverses within the oxide zone above the Rosie deposit, have indicated the presence of a 350m wide ‘high-grade’ platinum and palladium core outside of the current Ni-Cu-PGE resource.
Key results include:
- 17m @ 1.02g/t Pt and PD, 0.18% Ni and 0.27% Cu from 15m, incl. 6m @ 1.42g/t Pt and Pd, 0.34% Ni and 0.45% Cu
- 7m @ 2.13g/t Pt and Pd, 0.82% Ni and 0.29% Cu from 68m
- 10m @ 1.29g/t Pt and Pd, 0.68% Ni and 0.30% Cu from 45m, incl. 6m @ 1.79g/t Pt and Pd, 0.74% Ni and 0.36% Cu
- 9m @ 1.12g/t Pt and Pd, 0.67% Ni and 0.27% Cu from 82m
- 4m @ 2.95g/t Pt and Pd, 1.25% Ni and 0.99% Cu from 72m
Speaking on the results, DKM Managing Director, Stuart Fogarty, said: “Drilling into the transitional and oxide zone above Rosie continues to be a success – with every completed hole over a 900m length intersecting mineralisation. Within that 900m strike there is a higher-grade 350m long zone with greater than 2g/t of platinum and palladium starting at less than 12m from surface.
“Drilling into the transitional and oxide zone above Rosie continues to be a success”
These results reinforce the continuity of PGE grades above the fresh sulphide zone at Rosie, which is very encouraging for the future development options of the project. I am confident Duketon remains well funded with circa $18 million cash to pursue this and all other opportunities in its portfolio.”
The company also notes that individual samples taken from this drill area have returned Pt and Pd grades of up to 6.38g/t, reinforcing the potential for continuous ‘high-grade’ mineralisation to exist only 12m from surface across the ‘higher-grade’ 350m long zone.
In addition, it is reported that all drill holes will be submitted for analysis in order to identify the full suite of PGEs, including rhodium, ruthenium, iridium and osmium.
With results from the RC drilling now returned, Duketon Mining announces that it will move forward with additional drilling in the area with the goal of modelling a Ni-Cu-PGE resource.
The Duketon Project is located north of the township of Laverton within the ‘highly prospective’ Duketon Greenstone Belt of Western Australia. It comprises a tenement package that lies along strike and adjacent to Regis Resources’ (ASX:RRL) landholding, including the Garden Well, Rosemont, and Moolart Well gold mines.
The project’s associated Rosie Deposit currently boasts an updated JORC Mineral Resource Estimate (MRE) of 2.56Mt @ 3.14% Ni-Eq, containing 49,100 nickel tonnes, 10,600 copper tonnes and 205,000 ounces PGEs.
