Alto Metals Limited is a gold and base metals explorer holding a significant land position in the historic Archaean Sandstone Goldfield approximately 600km north of Perth in the East Murchison Mineral Field of Western Australia.
Historic production from the Sandstone Goldfield is approximately 1.3 million ounces, with half of this being mined in the period 1894-1914, and the remainder being mined by Herald Resources Ltd and Troy Resources Ltd from relatively shallow open pits at Oroya, Bulloak, Bulchina, Lord Nelson and Lord Henry in the period 1993-2008.
Alto’s immediate focus is the delineation of a combined 1 million ounce (JORC 2012) Mineral Resource. This will be comprised of relatively shallow gold deposits (new deposits such as Vanguard, Indomitable, Maninga Marley and others) and existing deposits (such as Lord Nelson and Lord Henry) that can be profitably mined through re-establishment of standalone oxide and primary gold mining operations at Sandstone.
Ultimately, Alto aims to find at least 5 million ounces of gold at Sandstone, which is comparable to discoveries in other more intensely explored greenstone belts in the Yilgarn of Western Australia.
Contemporaneously with the gold exploration program, Alto has commenced exploration for nickel/copper/cobalt sulphide deposits within the komatiite sequences in the southern portion of the Sandstone greenstone belt.
Research work undertaken by Geological Survey of Western Australia and University of Western Australia in 2005 identified abundant komatiites in the Sandstone greenstone belt, and highlighted their potential for sulphide nickel deposits. The discovery in 2010 of disseminated and semi-massive nickel sulphides (26.2m at 0.4% Ni from 60m depth in hole WAD002), including a 20cm interval of semi-massive sulphide which assayed 4.1% Ni from 86.3m depth, by Western Areas NL has confirmed their potential.
Since acquiring the Sandstone Project in June 2016, Alto has compiled and reviewed a large legacy database ahead of a series of focused exploration and drilling campaigns which commenced late 2016.
Alto has an experienced Board of Directors with extensive skills in exploration, mining, accounting, corporate governance and provision of corporate advice.
Alto’s existing gold resource base consists of 2.331Mt at 1.8g/t Au for 137,000 ounces (Inferred and Indicated, JORC 2012) and 2.076Mt at 1.9g/t Au for 125,000 ounces (Inferred and Indicated, JORC 2004*) Refer Mineral Resource Tables under Sandstone Project for details.
