Company & History

Stonewall Resources is an Australian public company listed on the ASX (ASX code: SWJ, SWJO). It was listed on the ASX through a reverse takeover listing of Meridien Resources in 2012.

Our gold projects are mostly fully permitted underground mines or open-cut resources with combined JORC resources of 34.7Mt @ 4.6g/t Au for 5.15Moz (27% indicated and 73% inferred, with 70% underground resources).

All underground 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, the site of a major gold rush in 1873.

The TGME project portfolio has more than 43 historical mines across the large tenement area of 62,000 hectares. In addition to the 5.15Moz in resources, the area has a number of underexplored old mines and shallow exploration targets containing gold-bearing ore left over from almost a century of mining. Much of it we believe to be accessible by reopening existing shallow-angle haulages and adits. When mining became difficult back in the day, miners just left to pursue other areas. Modern techniques and high-powered machinery for open-cut, combined with accurate laser surveying, resource modelling and modern processing technology allows these old prospects to be exploited once again.

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.

Our past focus was on underground mining. However, the latest strategy is to delineate high grade open cut resources, which have a lower capital and lower risk profile, and this is proving to be the right one. Several discoveries have been made through drilling, including the high grade Theta Hill (and in particular Lower Theta Reef).
