¹	Metal figures are fully inclusive of all mining dilutions and gold losses, and are reported as mill delivered tonnes and head grades. Metallurgical recovery factors have not been applied to the reserve figures.
²	Represents Harmony’s equity portion of 50%. NB Rounding of numbers may result in slight computational discrepancies. Note: 1 tonne = 1 000kg = 2 204lb.
