Harmony’s quarterly production guidance Harmony Gold Mining Company Limited Registration number 1950/038232/06 Incorporated in the Republic of South Africa ISIN: ZAE000015228 JSE share code: HAR (“Harmony” or “the company”) Harmony’s quarterly production guidance •Continued upward trend in performance quarter on quarter - build-up in gold production in both South Africa and Papua New Guinea (PNG) - increase in underground grade continues • Decrease in unit costs and capital Harmony Gold Mining Company Limited („Harmony?) is pleased to advise that production at its underground mines in South Africa is approximately 15% higher than the previous quarter, while Hidden Valley's production has increased by about 7%. Harmony's total production is expected to be around 12% higher quarter-on-quarter, mainly due to an increase in both tonnes and grade. During the September quarter there were increases in labour costs (following the new two year wage agreement) and electricity costs (winter tariffs). These cost increases were more than off-set by the increased production and savings in overall costs, resulting in our cash cost per kilogram being 6% to 8% lower quarter on quarter. “We are pleased that we have been able to deliver another solid performance for the quarter. That production is up in South Africa despite the labour disruptions experienced around wage negotiations, is testimony to our commitment to deliver in line with our guidance, and a credit to our management and employees”, said Graham Briggs, chief executive officer of Harmony. Harmony?s results for the quarter ended 30 September 2013 will be released on Friday, 8 November 2013 via webcast and conference call only.
