Impairment of Hidden Valley asset
Johannesburg. Tuesday, 18 June 2013. Harmony Gold Mining Company Limited
(“Harmony” or the “Company”) is currently compiling its financial year 2014 business
plans, which will be completed by the end of its 2013 financial year, being 30 June 2013.
Once approved, Harmony will use these plans to assess the carrying value of its assets to
determine if any impairments are required (“impairment testing”). This will be informed by
a number of factors, including estimates of the future gold price and exchange rates, life
of mine plans, and operating and capital cost estimates.

At this early stage it appears likely that there will be a write-down of a portion of the
carrying value of Hidden Valley in Papua New Guinea, due to its recent poor performance
and the reduction in the US dollar gold and silver prices.

Harmony will advise the market of the outcome of the impairment testing, which the
Company anticipates to be towards the end of July 2013. It should be noted that the write-
down of the carrying value of Hidden Valley will reduce the net profit of the company, but
will not have an impact on reported cash balances and free cash flow.
