Gold explorer Alto Metals (ASX:AME) is engaging in a second phase of deeper reverse circulation (RC) drilling at the Indomitable Camp within its Sandstone Gold Project in Western Australia.
This program comprises 5,000m of RC drilling to follow up on a drilling program completed earlier this year, targeting interpreted ‘high-grade’ structures uncovered from drilling in late 2022, and to test strike extensions of the existing mineralisation in primary rock.
Alto says this current program marks the deepest RC drilling conducted at Indomitable to date, with drillholes planned to a downhole depth of 300m.
The drilling program is still ongoing, with further assays pending from the remaining 4,000m of drilling planned. The company is also in preparation for follow-up diamond drilling.
This news follows the receipt of initial assays for the first 4 RC holes, which confirm ‘high-grade’ gold mineralisation, including hole SRC941 with 24m @ 2.2g/t Au from 160m, including 16m @ 3g/t Au from 167m, 1m @ 8.8g/t Au from 175m, and 1m @ 9.4g/t Au from 182m.
Commenting on the results, Alto Metals Managing Director Matthew Bowles says: “Whilst very early in the program, and not to be taken out of context, the initial results from these first holes is encouraging and represent the deepest significant gold mineralisation intersected at Indomitable.
SRC941 returning 24m @ 2.2g/t Au from 160m in oxide again highlights the significant depth of weathering in the system and the potential for mineralisation in primary rock at depth.
“This phase of drilling at Indomitable is ongoing and is targeting the orientation of the interpreted high-grade structures within the fresh rock”
This phase of drilling at Indomitable is ongoing and is targeting the orientation of the interpreted high-grade structures within the fresh rock, including the recently announced 16m @ 13.1g/t Au from 19m intersected in SRC918. We look forward to updating shareholders with our ongoing exploration activities over the coming months.”
Additionally, the results support Alto’s view that the size and scale of the oxide mineralisation at Indomitable is a ‘strong’ indication of a much ‘larger’ system.

Alto Metals is an ASX-listed gold exploration company holding a ‘significant’ land position of over 740km-square in the Archaean Sandstone Goldfield, located about 600km north of Perth in the East Murchison Mineral Field of Western Australia.
