EM is an established mine, with a Concentrator Plant that produces PGM and chromite concentrate.
Two different mining methods are undertaken at EM at two sections, namely underground mining at Elandsfontein and opencast mining at Zilkaatsnek.
Elandsfontein
Opencast mining operations commenced in 2006 prior to the commissioning of the Concentrator Plant, to build up an ore stockpile. The opencast workings were accessed via two boxcuts, located along the length of the UG2 outcrop. Mining took place on both sides of each of the boxcuts (SLR, 2012). Excess waste rock was used for the construction of the TSF Paddocks and roads.
The opencast reserves on the Farm Elandsfontein have been mined out (SLR, 2012).
The underground mining operation is divided into two mining blocks. These areas are accessed through two decline portals in the high wall of the initial opencast boxcuts (SLR, 2012). These are referred to as the Nyala (eastern portal) and Kukama (western portal) Shafts. Each portal contains two declines, providing access to the underground workings.
Zilkaatsnek
The mining method for the Zilkaatsnek opencast operation comprise of a series of boxcuts, which, once the ore has been removed, the next cut of overburden is removed and the initial void backfilled. Voids will be backfilled as part of the EP Proposed Projects.
Re-mining
EP has been authorised to re-mine the tailings in Paddock 1. The tail ........
