Origin of Material

This standard is made from uranium bearing gold ore originating from the Ventersdorp, Contact Reef, Carbon Leader Reef and Vaal Reef. The uranium bearing ore was blended with low grade material of similar matrix to obtain the required grade.

Approximate Mineral and Chemical Composition

Throughout the Witwatersrand, gold ores occur in sheets or reefs originally deposited horizontally under water. The thickness of the reefs range between a lie of grit to several meters, with an average of 300mm. The sediments were also intersected by dykes and sills of dolomite, diabase and syenite intruding existing faults. The reefs can be in the form of either course conglomerates, rock pebbles and cemented in a silicate matrix. Pebbles usually derived from vein quarts, may also consist of quarzitic, chert jasper and quartz porphyry. The matrix consists of pure silica, but also contains minute flakes of muscovite and pyrophyllite as well as visible pyrite and other sulphides. The gold is usually confined to the matrix and tends to be concentrated along bedding planes (Vermeulen, 2001).
