- 29 metres @ 1.51 g/t 3E (1.24 g/t Pd, 0.20 g/t Pt, 0.07 g/t Au), 0.23% Cu & 0.27% Ni from 255m (NRCD319) including: 11 metres @ 2.50 g/t 3E (2.08 g/t Pd, 0.31 g/t Pt, 0.11 g/t Au), 0.37% Cu & 0.40% Ni from 269m
- Metallurgical twin drill hole NRCD337 (2) confirms high-grade shallow mineralisation. Metallurgical program has commenced with flotation tests focussed on metal recoveries;
- 34 metres @ 1.97 g/t 3E (1.60 g/t Pd, 0.28 g/t Pt, 0.09 g/t Au), 0.31% Cu & 0.31% Ni from 142m (NRCD337) including: 17 metres @ 2.36 g/t 3E (1.91 g/t Pd, 0.33 g/t Pt, 0.12 g/t Au), 0.38% Cu & 0.35% Ni from 153m
- Drilling is planned to resume mid-January with the diamond rig targeting high grade palladium-nickel-copper zones to the east of current mineralisation
- Further assays pending for more than 15 RC and diamond drill holes
Ongoing drilling at Callisto continues to deliver consistently high-grade results with the latest assays showing that palladium, nickel, and copper grades are steadily increasing over wide intervals of mineralisation,” Managing Director Brad Underwood said.
“We are also seeing the highest individual copper and gold grades drilled to date which indicates we have yet to understand the full potential of this very large geological system. Geological interpretation suggests that the Callisto rock unit originated further to the east and that the ultimate source of mineralisation may yet be discovered at this location. Diamond core drilling is planned to resume in mid-January and the first program of drilling will test this concept with step out drilling.
“In addition to the drilling at Callisto, the first programme of metallurgical work is underway using drill core from NRCD337. This initial sighter work will focus on flotation testing to determine recoveries of the key metals – palladium, nickel, copper, platinum, rhodium, and gold. Results from this work are expected within the first quarter of 2023.
“With a quickly evolving discovery at Callisto we anticipate that the first few months of drilling in 2023 will be critical in demonstrating the quality of mineralisation we have discovered. We look forward to updating the market with the results of our drilling and metallurgical work programmes.”
Drilling at Callisto is now focussed on determining the size and grade of the sulphide zone, and understanding the relationship with the much larger host sill, while looking for a possible source of the discovery to the east. Assays are pending for more than 15 diamond core and RC drill holes.
