    Artisanal mining in the Barberton region produces relatively large nuggets in reasonably profitable mining ventures. Formal mines, such as Agnes, Fairview, Consort, and Barbrook, are relative small, and artisanal mining is growing in the region. Since artisanal mining is illegal in South Africa, it is difficult to estimate its economic value.

    Historically, mercury was used extensively in placer gold mining in order to form mercury-gold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Large-scale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and small-scale gold mining (ASGM), often clandestine, gold prospecting.
