Alto Metals Limited (ASX: AME) has obtained further “outstanding” near surface high-grade gold results from ongoing drilling at the Indomitable Camp, within the company’s 100% owned, Sandstone Gold Project, in Western Australia.
Mineralisation at Indomitable Camp is hosted within a package of mafic-ultramafic rocks, cross-cut by interpreted major structures, with higher-grade gold mineralisation typically observed where the structures intersect the stratigraphy.
Recent drilling has targeted extensions of known mineralisation outside the current resource at Indomitable North and new target areas further north along the same major cross-cutting structures.
New assay results are from one-metre photon assays and relate to 37 RC holes drilled at Indomitable North for a total of 4,682m, drilled on a 40m x 40m spacing to an average downhole depth of 127m. Significant results include multiple, near surface high-grade gold results that have successfully extended the overall mineralised footprint.
Wide-spaced step-out drilling north of the Indomitable North deposit has extended mineralisation up to 500m outside the current resource.
Latest results include:
- 13m @ 4.6 g/t gold from 24m, incl. 1m @ 31.8 g/t gold from 27m (SRC628)
- 15m @ 4.2 g/t gold from 30m incl. 1m @ 38.0 g/t gold from 35m (SRC629)
- 6m @ 2.1 g/t gold from 41m (SRC643)
- 6m @ 2.4 g/t gold from 69m incl. 1m @ 7.4g/t gold from 70m (SRC644)
- 10m @ 1.0 g/t gold from 2m (SRC645) o 11m @ 1.1 g/t gold from 39m (SRC646)
Extensional drilling at Indomitable North has extended gold mineralisation outside the current resource.
Results include:
- 44m @ 2.0 g/t gold from 58m incl. 14m @ 3.2 g/t gold from 84m (SRC663)
- 7m @ 2.1 g/t gold from 9m (SRC655)
- 3m @ 1.7 g/t gold from 8m and 9m @ 1.9 g/t gold from 92m incl. 1m @ 5.3 g/t gold from 97m (SRC659)
- 9m @ 1.0 g/t gold from 66m (SRC662)
SRC628 and SRC629 were drilled north-west / south-east on 40m spacing, approximately 200m north west of Indomitable North.
Drilling outside of the optimised pit shell at Indomitable North has returned further high-grade mineralisation, including SRC663 which returned 44m @ 2.0 g/t gold from 58m, with mineralisation remaining open.
The Indomitable Camp is hosted within a granted Mining Lease and is located approximately 15km south-east of the town of Sandstone. It is in close proximity to the Sandstone-Menzies Road.
These latest shallow high-grade gold results are outstanding, with SRC628 and SRC629 extending mineralisation further north, outside the current resource,” Managing Director, Matthew Bowles, said.
“Our systematic approach is continuing to deliver and the ongoing near surface results from Indomitable highlight a very large shallow oxide footprint, which is often the key to finding much larger high-grade gold deposits at depth. Drilling at Indomitable is ongoing and we look forward to updating shareholders on further results in the coming weeks.”
