Company & History
Stonewall Resources is an Australian public company listed on the ASX (ASX code: SWJ). It was listed on the ASX through a reverse takeover listing of Meridien Resources in 2012.
Our gold projects are permitted underground mines, residual surface small tailings and small mineralised waste dumps with a combined JORC resources of 26.7Mt @ 4.34g/t Au for 3.72Moz gold. The underground resources total 17.8Mt @ 5.8g/t Au for 3.32Moz.
All gold mines are near surface, adit entry, historical mines located near the towns of Pilgrims Rest and Sabie in South Africa’s Eastern Goldfields (Mpumalanga Province). Pilgrims Rest is the birthplace of gold mining in South Africa.
Stonewall’s initial focus is on reopening the full permitted Rietfontein mine in our TGME project portfolio. This has an indicated and inferred resource (JORC 2012) of 2.55Mt @ 11g/t for 905,000oz of gold. The latest scoping study indicates a C1 cash cost of $US417/oz and an all-in sustainable cost of $US578/oz, which puts the project among the lowest cost producers around the globe.
The intention is to bring the Rietfontein project into production in 2018 in conjunction with our Beta project with its pre-mined residue and ramp up output to more than 100,000oz a year.
The TGME project portfolio has more than 40 historical mines across the large tenement area of 62,000 hectares. In addition to the 3.7Moz resources, it has approximately 35 million tonnes of pre-explored, pre-developed, pre-drilled, pre-blasted (in some cases) gold-bearing ore left over from almost a century of mining. It is easily accessible by reopening existing shallow-angle haulages and adits.
Stonewall has an existing carbon in leach treatment plant and intends to refurbish and expand the plant to enable rapid ramp-up of production across the whole project.
