Some 30km west of Johannesburg, Doornkop is a single-shaft operation mining the Kimberley and South Reefs to a depth of just under 2 000 metres. Doornkop uses both mechanised bord-and-pillar and narrow-reef conventional mining, with ore processed at its carbon-in-pulp plant. Production at the higher-grade South Reef project is ramping up to scheduled full production in FY16.
Doornkop’s operational difficulties during FY14 were exacerbated by safety-related stoppages following two fatalities earlier in the financial year and by the underground fire in February 2014 which resulted in nine fatalities. The fire necessitated a cessation of underground operations for four weeks while we ensured that working conditions were safe. We also conducted additional safety training to reinforce the importance of safe behaviour.
The scheduled production build-up was delayed and volumes for the year were adversely affected. Work on rehabilitating the area affected and providing alternative access, so as to restore production, continued into the June quarter while alternative lower-grade stoping panels were opened up. In the fourth quarter, more mining took place from the lower grade areas on 202 level which adversely influenced the recovered grade. This work was completed by year-end and the area is fully operational. Mining of the lower-grade Kimberley Reef was suspended during the year, resulting in improved and more consistent recovered grade. The focus now is on ramping up production from the higher-grade South Reef.
