GOLD MINERS ROUNDUP MAY 2018 • E&MJ; 35 www.e-mj.com lion last year. The company posted a loss for the year of $370 million, after posting a profit of $254 million for 2016. AISC rose 18% yoy to $1,128/oz, the highest since 2013. Total ore processed fell 16% yoy to 19 mt, and total gold output fell 7%, to its lowest level since 2012. The back story is the rand-to-dollar conversion. "In rand terms, the aver- age price received of R536,378/kg was 9% lower than the average received for 2016," the company reported. That de- velopment, and the build up to it, ren- dered the Cooke operation uneconomical, which was shuttered effective November 2017, and sparked a reduction in invest- ment at the Beatrix West operations. The latter "will continue operating its under- ground workings and surface processing with fewer employees," the company reported. "Should the section return to loss in any three-month period, there will be no alternative but to place it on care and maintenance." The cessation of underground opera- tions at Cooke contributed to the decline in company-wide production numbers. "Un- derground production from the Cooke oper- ations decreased by 52%," Sibanye-Still- water reported. "At Beatrix, underground gold production decreased by 8%." Underground production declined 21% yoy at Driefontein due to lower grades. Total gold output at Kloof un- derground production increased 8% yoy, with mill throughput reaching 2.2 mt, the company reported. "Surface throughput increased by 34% to 3.6 mt, owing to the greater volumes of Venterspost surface material treated at the Ezulwini plant." As of December 31, 2017, the com- pany reported reserves of 25.7 million oz. "This represents a reduction of 3 million oz (10%), which, after accounting for de- pletion of 1.5 million oz due to mining activities in 2017, equates to a 6% de- crease yoy." The company predicts 2018 gold pro- duction of between 1.24 million oz and 1.29 million oz. In March, the company will transfer assets from its West Rand
