Vametco 2023 Mineral Resources and Reserves Annual Update
Bushveld Minerals Limited (AIM: BMN), the primary vanadium producer, is pleased to provide an updated Mineral Resources and Ore Reserves for the Vametco vanadium mine near Brits on the Western Limb of the Bushveld Complex. The resources and reserve estimation was carried out by MSA Group Inc in accordance with the terminology and definitions given in the JORC Code (2012).
Key Highlights
· The total Ore Reserves have increased by approximately 10 per cent from the previous Ore Reserve estimate as at 31 December 2022. The Ore Reserves are reported as at the 31 December 2023 at 293,400 tonnes V2O5 in magnetite at a grade of 2.00 per cent V2O5 (in magnetite).
· The combined Inferred and Indicated Mineral Resource comprises 3 Seams (The Lower, Intermediate and Upper Seams) and is reported as at the 31 December 2023 at 180.4 million tonnes (Mt) at an average grade of 1.98 per cent V2O5 (in magnetite), with an average magnetite content of 35.0 per cent (in whole rock) for 694.6 thousand tonnes of contained vanadium. The previously reported combined Inferred and Indicated Mineral Resource, as a 31 December 2022, was 181.5 Mt at an average grade of 1.98 per cent V2O5 (in magnetite), with an average magnetite content of 35.0 per cent (in whole rock) for 699.0 thousand tonnes of contained vanadium.
· Within this, the Ore Reserve in the Probable Category comprise 3 Seams (The Lower, Intermediate and Upper Seams) and is reported as 51.0 Mt at an average grade of 2.00 per cent V2O5 (in magnetite), with an average magnetite content of 28.9 per cent (in whole rock) for 164,300 tonnes of vanadium.
· The Lower Seam is the main ore seam and the thickest, ranging from 13.8 to 52.0 metres in thickness, comprising a Probable Reserve of 41.2 Mt at an average grade of 2.03 per cent V2O5 (in magnetite), with an average magnetite content of 28.2 per cent (in whole rock) for 132,200 tonnes of vanadium.
· The decrease in the total 2023 Mineral Resource, by 0.61 per cent less tonnes than the 31 December 2022 estimate, is attributed to mining of the seams over the last 12 months. No Mineral Resource exploration was carried out over the period.
· The year-on-year depletion which was calculated to be 1.1 Mt, was offset by an increase in tonnage through improved definition of the existing pit design (1.7 Mt) and an adjustment to the modifying factors (4.1 Mt), resulting in an increase in the total Ore Reserves from 46.4 Mt to 51.0 Mt as at 31 December 2023. The Ore Reserve modifying factors (mining loss and dilution) were adjusted based on pit to plant reconciliation production data supplied by Bushveld Vametco Alloys (Pty). Ltd. This resulted in a significant increase in the Upper Seam ore tonnes from 36.2 Mt to 41.2 Mt.

Notes:
1. All tabulated data have been rounded and as a result minor computational errors may occur.
2. Mineral Resources which are not Ore Reserves have no demonstrated economic viability.
3. Mineral Resources are inclusive of Ore Reserves (not indicated in the table).
4. Magnetite content (grade) is determined as the proportion of magnetite concentrate recovered using Davis Tube methodology.
5. Due to the magnetite grade being a recovered grade, differences will occur between whole rock V2O5 grades back-calculated from concentrate, versus those derived from whole rock assays.
6. Depleted using the 31 December 2023 pit survey.
7. Reported on a Gross Basis. Bushveld Minerals shareholding in Bushveld Vametco Alloys is 100%
