Yandal Resources Ltd (ASX:YRL) has received final assay results from the reverse circulation (RC) drilling exploration program completed at Mt McClure in September.
Mt McClure can be found in the southern Yandal Greenstone Belt of Western Australia and includes roughly 60 square kilometres of tenure, including applications, 10 kilometres southwest from the historical Bronzewing mine and adjacent to the Orelia mine, both owned by Northern Star Resources (ASX:NST).
Emerging prospects
In September 2022, the company finished an RC program comprising 19 holes for 2,201 metres testing a range of new targets occurring along the main 10-kilometre-long mineralised horizon within its tenure.
The program returned several "highly encouraging" intersections and gave the company confidence in the potential of the emerging HMS Sulphur and Gilmore prospects.
They confirm that the mineralised horizon at HMS Sulphur, immediately to the northwest of the Success deposit, extends over 600 metres of strike.
Intersections at HMS Sulphur include:
- 14 metres at 1.3 g/t gold from 113 metres including 2 metres at 6.4 g/t from 119 metres;
- 8 metres at 1.7 g/t from 148 metres including 4 metres at 3.1 g/t;
- 4 metres at 1.2 g/t from 58 metres including 1-metre at 2.6 g/t from 58 metres; and
- 12 metres at 1.1 g/t from 100 metres including 5 metres at 2.1 g/t from 105 metres.
- 21 metres at 0.8 g/t gold from 90 metres including 3 metres at 2.5 g/t from 90 metres; and
- 17 metres at 0.6 g/t from 43 metres including 5 metres at 1.4 g/t from 45 metres.
“Clear potential”
“The RC program reported here was designed to test the potential of several earlier stage prospects at Mt McClure,” managing director Tim Kennedy said.
“It was undertaken in anticipation of a positive outcome from the initial mineral resource estimates (MRE) completed at the Success, Challenger and Parmelia deposits in August and September.
“Pleasingly, the results of the MRE confirmed there was clear potential to increase resources around those three deposits.
“This RC program has confirmed the potential of HMS Sulphur and Gilmore, which can now also be included in future drilling programs designed to enable a resource upgrade at Mt McClure.
“Phase 1 resource expansion drilling commenced earlier this month thanks to the efforts of our exploration team which was able to finalise approvals and secure a suitable rig shortly after the completion of Yandal’s successful $5 million capital raise in October.”
Both prospects are being further drilled tested as part of the current Phase 1 MRE upgrade RC program.
