Interest in the geology of the Barberton region stemmed from the discovery of gold there in 1884, and the subsequent development of a number of significant gold mines. Since the pioneering prospecting days at the end of last century, some 200 t of gold have been recovered from mining operations in the Barberton greenstone belt.
