BASE RESOURCES LIMITED
2018 Mineral Resources and Ore Reserves Statement

Summary

  • The recently acquired Toliara Project has an estimated Mineral Resource of 857 million tonnes at 6.2% Heavy Mineral (HM) in the Ranobe deposit.
  • The Kwale deposit was reduced by mining depletion in the year to 30 June 2018 with the effect of:
    • reducing the Central Dune Mineral Resources by 13Mt containing 0.9Mt of in situ HM; and
    • reducing the Central Dune Ore Reserves by 11Mt containing 0.8Mt of in situ HM.
  • The Kwale South Dune Mineral Resources estimate increase announced on 4 October 2017, delivered a 19% or 560kt increase in contained HM tonnes within the Measured and Indicated Resource categories.This increase was included in the 30 June 2017 Kwale Mineral Resources estimate.

The 2018 Mineral Resources and Ore Reserves for Base Resources (ASX & AIM: BSE) are summarised in the table below together with the 2017 Ore Reserves and Mineral Resources for comparison.

Kwale Deposits

The Company’s Kwale Operation contains the Kwale Central Dune and South Dune deposits, located approximately 50 kilometres south of Mombasa and approximately 10 kilometres inland from the Kenyan coast.

Mineral Resources

The 2018 Kwale Mineral Resources, as at 30 June 2018, are estimated to be 134Mt at an average HM grade of 3.1% for 4.2Mt of contained HM, at a 1% HM cut-off grade.  The 2018 Kwale Mineral Resource estimate has decreased by 9% for material tonnes and by 18% for contained HM tonnes when compared with the previous 2017 Kwale Mineral Resource estimate due to mining depletion.

The Kwale Central Dune Mineral Resources at 30 June 2018 are estimated to be 20Mt at an average HM grade of 3.9% for 0.8Mt of contained HM, decreased by 13Mt containing 0.9Mt of HM compared to the 2017 estimate due to mining depletion during the year.  The South Dune Mineral Resources at 30 June 2018 are unchanged from the 2017 estimate as the increase announced on 4 October 2017, was incorporated into the 2017 estimate and mining has not yet commenced on this deposit.

Ore Reserves

Contained within the Kwale Mineral Resources are the Kwale Ore Reserves, estimated as at 30 June 2018 to be 80Mt at an average HM grade of 3.9% for 3.1Mt of contained HM.  The 2018 Kwale Ore Reserves estimate represents a decrease of 13% in total ore tonnes and 22% in contained HM tonnes over the previously reported 2017 Kwale Ore Reserves estimate.

The Kwale Central Dune Ore Reserves at 30 June 2018 are estimated to be 18Mt of ore at an average HM grade of 4.0% for 0.7Mt of contained HM, decreased by 11Mt containing 0.8Mt of HM compared to the 2017 estimate due to mining depletion during the year. 

Mining has not yet commenced on the South Dune and its Ore Reserves estimate is therefore unchanged from the 2017 estimate.

As announced on 4th October 2017[2], an updated Mineral Resources estimate for the Kwale South Dune (the 2017 Kwale South Dune Mineral Resource) was completed, resulting in a 19% increase in contained HM tonnes in the Measured and Indicated categories.  Completion of an updated Kwale South Dune Ore Reserves estimate based on the 2017 Kwale South Dune Mineral Resource is subject to finalisation of mining tenure arrangements, which are currently being progressed with the Kenyan Ministry of Petroleum and Mining.

Ranobe Deposit

The Company completed the acquisition of the Toliara Project on the 23rd January 2018 and is currently progressing the project through a full study phase.  The Toliara Project is founded on the Ranobe deposit, located approximately 40 kilometres north of the town of Toliara in south west Madagascar and approximately 15 kilometres inland from the coast.

Mineral Resources

The 2018 Ranobe Mineral Resources as at 30 June 2018, are estimated to be 857Mt at an average HM grade of 6.2% and 4% slimes containing 53Mt HM, based on a 3% HM cut-off grade.

GLOSSARY

Assemblage the relative proportion of valuable heavy mineral components of ilmenite, rutile and zircon
Competent Person The JORC Code requires that a Competent Person must be a Member or Fellow of The Australasian Institute of Mining and Metallurgy, or of the Australian Institute of Geoscientists, or of a ‘Recognised Professional Organisation’. A Competent Person must have a minimum of five years’ experience working with the style of mineralisation or type of deposit under consideration and relevant to the activity which that person is undertaking.
Cut-off grade An industry-accepted standard expression used to determine what part of a mineral deposit to include in a Mineral Resource Estimate or Ore Reserve Estimate.
Grade The percentage of heavy mineral found in a deposit.
Heavy mineral In mineral sands, heavy minerals with a specific gravity greater than 2.85 t/m3.
ILM Ilmenite, a valuable heavy mineral.
Indicated Resource An Indicated Mineral Resource is that part of a Mineral Resource for which quantity, grade (or quality), densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit.
Inferred Resource An Inferred Mineral 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 The Joint Ore Reserves Committee: The Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (‘the JORC Code’), as published by the Joint Ore Reserves Committee of The Australasian Institute of Mining and Metallurgy, Australian Institute of Geoscientists and Minerals Council of Australia.
Measured Resource A Measured Mineral Resource is that part of a Mineral Resource for which quantity, grade (or quality), densities, shape, and physical characteristics are estimated with confidence sufficient to allow the application of Modifying Factors to support detailed mine planning and final evaluation of the economic viability of the deposit.
Mineral Resources Mineral Resources are a concentration or occurrence of solid material of economic interest in or on the Earth’s crust in such form, grade (or quality), and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity, grade (or quality), continuity and other geological characteristics of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge, including sampling.  Mineral Resources are sub-divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories.
Ore Reserves Ore Reserves are the economically mineable part of Measured and/or Indicated Mineral Resources.
OS Oversize material.
RUT Rutile, a valuable heavy mineral.
SL Slimes, being a waste product from the processing of mineral sands.
ZIR Zircon, a valuable heavy mineral.
