  • Rounding of figures may cause computational discrepancies.
  • Percentage zinc (% Zn), percentage copper (% Cu), percentage lead (% Pb), grams per tonne silver (Ag g/t), percentage manganese (% Mn) and percentage sulphur (% S).
  • Tonnages are quoted in metric tonnes and million tonnes is abbreviated as Mt.
  • Reserves are quoted on a RoM Reserve tonnage basis, which represents tonnages delivered to the plant at applicable moisture and quality.
  • Inferred Resources in LoMP refer to Inferred Resources considered for the LoMP.
  • Estimates are as received from Vedanta Resources at 31 March 2023 and are not audited by Exxaro.
  • All changes more than 10% are explained.
1 Operation refers to the BMM operating mine or significant project. Mining method: opencast (OC) or underground (UG).
2 Figures are reported at 100%, irrespective of percentage attributable to Exxaro, and refer to March 2023 only.
3 The percentage difference between 2023 reported RoM and 2022 reported RoM. Brackets signify a decrease.
4 The decrease is the result of mining depletion and updated Australian mining consultants stope designs.
5 The increase is the result of additional stope designs provided for the current UG mine.
