Year in Review: Alto Metals spends 2022 growing resource base at Sandstone Gold Project

Alto Metals (ASX:AME) has spent the majority of 2022 exploring various deposits at the Sandstone Gold Project.

The Western Australia-based gold explorer grew its resource base at multiple deposits within the Sandstone Project.

The Sandstone Project covers a large area in the Archaea Sandstone Goldfield around 600km north of Perth in the East Murchison Mineral Field of Western Australia.

H1 2022 delivers ‘high-grade’ results and resource growth

In February Alto reported that results from a 22-hole program extended gold mineralisation outside of the current 74,000oz @ 1.5g/t resource at Indomitable, with key hits including 21m @ 2g/t Au from 46m inclusion 1m @ 14.9g/t Au from 61m and 1m @ 6.3g/t Au from 66m.

Then in March the company reported a significant boost to the Mineral Resource Estimate at its Sandstone Gold Project in Western Australia after incorporating updates for the Lord Nelson, Lord Henry, Havilah Camp, and Vanguard Camp targets which brought the MRE to 12.4Mt @ 1.6 g/t gold for 635,000oz of contained gold, representing an increase of 92% in contained gold at an average discovery cost of less than $14 per ounce.

For the rest of H1 2022, Alto reported finding ‘high-grade’ gold results at Lord Nelson Pit and Juno Load.

Doubling down on high-grade results in H2 2022

Throughout H2 2022, Alto Metals received more ‘high-grade’ gold results from various deposits at the Sandstone Project.

In July the company reported further outstanding near surface ‘high-grade’ gold results from drilling at the Indomitable Camp.

Step-out drilling north of the Indomitable North deposit had also extended mineralisation up to 500m north of the current resource and at the time was reported to remain open.

In August, Alto received further ‘excellent high-grade’ gold results from ongoing drilling at the Indomitable Camp.

Significant new near surface ‘high-grade’ gold results included 20m @ 6.9 g/t gold from 35m including 1m @ 97.8 g/t gold from 38m (SRC674).

In mid-October Alto reported it had uncovered ‘high-grade’ gold targets at the Oroya and Hacks reefs providing an exciting opportunity to re-explore these ‘long forgotten’ mines.

This also aligned with the company’s strategy of focusing on growing its existing resource base within the Alpha Domain, while progressing regional prospects.

Drilling programs continued throughout the remainder of H2 2022 with drilling at Musketeer, Indomitable and Oroya delivering further ‘high-grade’ gold results.

In 2023 Alto will be focused on expanding the current mineral resources with further exploration, including further exploration including step-out and infill drilling targeting shallow gold deposits.

The company will also focus on extension and primary zone discoveries around previously partial-mined deposits.
