The Reserve declaration excludes Rand Uranium Reserves (which is being held for sale), as well as some
Evander projects which are no longer included in Harmony’s long term mine plans. These exclusions,
together with mine depletion, resulted in a decrease of 6.5 million ounces year on year, allowing Harmony to
focus on growing, developing and operating its portfolio of quality assets.
As at 30 June 2011 attributable gold Mineral Resources are 163.9 Moz. Harmony’s PNG Resources
represent 10% of Harmony's total Resources at 16.3 Moz – a 51% increase in the total amount of
Resources from PNG, largely due to the significant increase in the
Wafi-Golpu Resource (jointly (50/50) held by Harmony and Newcrest Mining Limited (Newcrest) in the
Morobe Mining Joint Venture).
The Wafi-Golpu Resource statement confirms Harmony’s long held belief that Golpu is truly a world-class
discovery. On a 100% basis, Golpu alone now hosts a Resource of 869Mt, containing 19.3Moz of gold and
9.0 million tonnes (Mt) of copper (62Moz on a gold equivalent
1
basis). This represents a significant year-on-
year increase, with an additional 368Mt (73% increase), comprising 4.2Mt copper (88% increase) and
10.5Moz of gold (119% increase) (see Table 1 below). The deposit has grown to the north and at depth, and
the grade has also increased. The Resource remains open at depth and to the north, with extension and infill
drilling continuing (see Figure 1 below).

Graham Briggs further commented, “The Golpu deposit benchmarks as one of the highest grade copper-gold
deposits in South East Asia, and there is potential to improve this further. The ultimate size of the system,
including the gold mineralisation, is yet to be realised, but significant potential remains for additional growth
in the district or as additional mineralisation centres aligned along the Wafi transfer structure. We are
increasing the drill fleet from 5 to 8 rigs over the coming months to realise this potential”.
