The Phoenix operation, located adjacent to Harmony’s current and historical operations in the Free State, involves the retreatment of tailings from tailings storage facilities in the region to extract any residual gold. Material contained in the TSFs originates from deep level gold mines, operated by Harmony and other mining companies. The mining operations predominantly extract narrow, tabular gold-bearing conglomerate reefs, namely the Basal, B, Elsburg (EA), Dreyerskruil and Beatrix Reefs. These reefs occur within the Archean Witwatersrand Basin which hosts the Witwatersrand Supergroup succession. The Basal Reef is located at the base of the Harmony Formation, within the Johannesburg Subgroup of the Central Rand Group (“CRG”). The B Reef is part of the Spec Bona Member at the base of the Aandenk Formation, within the Turffontein Subgroup of the CRG. The Beatrix Reef is part of the Earls Court Member of the Aandenk Formation, within the Turffontein Subgroup of the CRG. The Elsburg (EA) and Dreyerskruil Reefs occur within the Eldorado Formation of the Turffontein Subgroup, capping the CRG in the Free State Goldfield. The TSF material is the waste product of crushing, milling and gold extraction by carbon-in-leach (“CIL”) or CIP methods. As man-made deposits the TSFs are not the result of natural sedimentary processes. The grade of the TSFs is a function by the grade of the original reef sources, and the efficiency of the processing method at the time of treatment.
