Probably the first occurrence to be prospected is that known as the Maitland Mines in the Division of Uitenhage. According to F.L. Amm there are records of analyses of the ore of these deposits dating as far back as 1792. Henry Lichtenstein visited the deposits in 1805 and they were also examined at the time when General Jansens was Governor of the Cape. In 1856 they were reported on by A. Wyley, who found that there had been a considerable amount of underground exploration without any apparent measure of success. The deposits were again actively prospected in 1924 and 1925 and intermittently in a smaller way up to 1931. Most of the workings encountered small veins and narrow beds of rock impregnated with ore, but never revealed a lode or large body of the ore sufficiently remunerative to warrant working it. The structure of the bluish dolomitic limestone, which is the main ore-bearing formation, is that of a simple syncline, both limbs of which dip towards the river. The trough of the syncline was considered to be a likely spot for developement of a large ore-body and many deep borings were made, but to no avail. The ore consists of argentiferous galena, chalcopyrite and chalcocite with malachite and azurite, in irregular stringers and elongate nodules. The association of ore with irregular veins of calcite in the dolomitic limestone indicates developement of minerals along zones of crush.
