Blanket Gold Mine - Caledonia Mining Corporation plc

The majority of the mine production is sourced at present from the AR Main and AR South ore bodies with a lesser contribution from the Blanket, Eroica and Lima reefs. AR Main and AR South are massive ore bodies up to 30 m wide and are ideally suited to the long-hole open stope mining method, while the remainder of the Blanket ore bodies are tabular and better suited to underhand stoping methods.

Additionally, the annual production of platinum from this mine is only about 1.5% of available platinum for each 1 km of depth (Cawthorn, 2010). However, problems with supply may arise from the political and social conflicts in the mining regions, particularly in South Africa, which has 80% of the world's PGE reserves (see PGE Supply and Demand Page) ("South Africa's Mining Problems").
