Alto Metals Limited reported that as part of its ongoing regional evaluation of the multiple advanced prospects within the Company's 100% owned Sandstone Gold Project, a targeting review of both the historic high-grade Hacks and Oroya gold mines and near mine area has identified a number of priority targets. Work towards developing initial drill targets is ongoing through a combination of structural and geological targeting and review of the historic data sets and recently acquired digitised historic mined void models. The company considers there is potential for significant mineralised material to remain due to historical mining activities at Oroya and Hacks focusing only on bonanza style mineralisation within the reefs (and later open-pit mining at a gold price of US$380/oz) leaving surrounding mineralisation unmined; as highlighted by the historical results drilled post mining.

The Oroya and Hacks mines were major gold producers, together accounting for almost 40% of the total gold production from the Sandstone Greenstone Belt. Despite the historical production and numerous old workings over the areas, there has been limited modern exploration undertaken over these prospects. The lack of recent exploration and numerous historic high-grade drill results provides an exciting opportunity for Alto to re-explore these `long forgotten mines' 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.
