Resources & Reserves

The main features relating to Implats’ mineral resources as at 30 June 2013 relative to 30 June 2012 are:

  • Estimated total attributable mineral resources increased marginally by 1Moz 4E to 425Moz; the total attributable platinum ounces remained constant at 230Moz
  • Attributable mineral resources remain dominated by Zimplats and Impala. Some 44% of the attributable Implats mineral resources is hosted by the Great Dyke; the Zimplats mineral resources make up the bulk of these (42%)
  • Year-on-year comparisons show a stable inventory, although additional work resulted in updated estimates in certain areas
  • Steady progress is being made to convert mineral resources from the inferred category to an indicated and measured status. Altogether 56.7% of attributable mineral resources are in the indicated and measured categories, compared to 53.1% in 2012 and 51.4% in 2011.

The main features relating to Implats’ mineral reserves as at 30 June 2013 relative to 30 June 2012 are:

  • Total attributable mineral reserves decreased by 1Moz 4E to 60Moz; the attributable platinum ounces decreased by 1Moz to 33Moz
  • Mineral reserves are reasonably spread between the different reefs; the Merensky Reef contributes the smallest proportion of the Group attributable mineral reserves
  • Some 59% of the attributable mineral reserves are located at Impala, where it is evenly spread between Merensky and UG2, however, the quantum of proved Merensky reserves remains low at some 20% below the same for the UG2 Reef
  • The overall comparison does not show material differences over and beyond depletion, despite several movements at shaft level.
Importantly it must be noted that as at 30 June 2013 the indigenisation transactions at both Mimosa and Zimplats have not been concluded. Once concluded Implats’ mineral resources and mineral reserves may be significantly reduced.
