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.
