«The reduced full year guidance [at South Deep] is attributable to the ongoing impact of
poor equipment reliability, the slower advance rates in Corridor 3 and delayed extraction in the composites, as well as slower rates of destress in the March quarter, again a symptom of the lower productivity related to uncertainty around the labour restructuring,» Gold Fields CEO Nick Holland said.
Other reasons for uncertain performance and
reliability could be due to
poor manufacturing, a lack of adequate testing in hot or dusty environments, or limited local capacity to maintain and repair
equipment.
