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.

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.

Glossary of Technical Terms

 

Cut-off grade

The lowest grade, or quality, of mineralised material that qualifies as economically mineable and available in a given deposit. May be defined on the basis of economic evaluation, or on physical or chemical attributes that define an acceptable product specification.

Cut-off grade

The lowest grade, or quality, of mineralised material that qualifies as economically mineable and available in a given deposit. May be defined on the basis of economic evaluation, or on physical or chemical attributes that define an acceptable product specification.

Indicated Mineral Resources or Indicated Resources

Indicated Mineral Resource or Indicated Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics, can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed

Inferred Mineral Resources or Inferred Resources

An Inferred Mineral Resource or Inferred Resource is that part of a Mineral Resource for which quantity and grade (or quality) are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade (or quality) continuity. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.

JORC Code

The Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the "JORC Code"), a professional code of practice that sets minimum standards for Public Reporting of minerals Exploration Results, Mineral Resources and Ore Reserves.

Magnetite

Naturally occurring form of iron ore with the formula Fe3O4.

Mt

Millions of tonnes

mt or mtV

Metric tonne or Metric tonne of Vanadium

Ore or Mineral Reserves

Ore or Mineral Reserves are sub-divided into two categories. The "Proved" category - the highest level of Reserves or the level with the most confidence and the "Probable" category - the lower level of confidence of the Reserves.

 

Reserves are distinguished from resources as all the technical and economic parameters have been applied and the estimated grade and tonnage of the resources should closely approximate the actual results of mining. The guidelines state: "Mineral Reserves are inclusive of the diluting material that will be mined in conjunction with the Mineral Reserve and delivered to the treatment plant or equivalent facility." The guidelines also state that:

 

"The term 'Mineral Reserve' need not necessarily signify that extraction facilities are in place or operative or that all government approvals have been received. It does signify that there are reasonable expectations of such approvals."

Seam

A bed or a distinct layer of vein of rock in other layers of rock

Vanadium

Vanadium is a chemical element with the symbol V and atomic number 23.

Vanadium Oxide

Vanadium(V) oxide is the inorganic compound with the formula V2O5.
