Alto Metals Limited reported that following a targeting review of both the historic Hacks and Oroya gold mines, within the Company's 100% owned Sandstone Gold Project, which identified a number of priority targets, a planned 2,000 metre maiden RC drilling program is now underway at the historic high-grade Oroya gold mine. The Company considers there is potential for significant mineralised material to remain due to historical mining activities at Oroya focusing only on bonanza style mineralisation within the reefs (and later open-pit mining at a gold price of USD 380/oz) leaving surrounding mineralisation unmined; as highlighted by the historical results drilled post mining. This initial drill program is the first RC drilling at Oroya in over 15 years and is targeting extensions of the Sandstone reef mineralisation to the north-west beyond the north end of the pit, along with extensions to the south and down dip to the west, which have not been adequately tested.

The lack of recent exploration and numerous historic high-grade drill results at Oroya, provides an opportunity for Alto to re-explore this `long forgotten mine' and fits with the Company's strategy of continuing to focus on growing its existing resource base within the Alpha Domain, while progressing regional prospects. Highlights: Historical results highlight significant high-grade mineralisation remains below the shallow-mined Oroya pit (60m depth) and along strike and down dip of the underground workings of the main reef, including: 23m @ 6.2 g/t gold from 87m, incl. 2m @ 55.9 g/t gold from 89m (NT5020R) - NW Extension; 8m @ 17.9 g/t gold from 69m, incl.

1m @ 137.0 g/t gold from 73m (NT5026R) - Main Reef; 9m @ 14.6 g/t gold from 42m, incl. 1m @ 120.0 g/t gold from 42m (MSGC1312) - Juno/Main Reef; 6m @ 8.3 g/t gold from 49m, incl. 2m @ 23.2 g/t gold from 51m (MSGC0886) - Main Reef; 13m @ 3.1 g/t gold from 22m, incl.

2m @ 11.9 g/t gold from 28m (MSGC0933) – Juno; 8m @ 10.1 g/t gold from 44m, incl. 1m @ 50 g/t gold from 47m (MSGC1136) - Oroya West. The Oroya Mine produced 220,000oz at 16.5 g/t gold from underground mining between 1904-1920 and a further 25,000oz at 2.3 g/t gold from open pit mining from 1994-1995.
