Katanga Mining announces ore reserves and mineral resources

ZUG, Switzerland, Feb. 10, 2014 /CNW/ - Katanga Mining Limited (TSX: KAT) ("Katanga" or the "Company") is pleased to announce its ore reserve and mineral resource estimates as at December 31, 2013.

Key Updates: Mineral Resources

  • Overall, the measured and indicated mineral resource for Kamoto Copper Company ("KCC") (in which the Company has a 75% interest) decreased by 5.2 million tonnes.
    • Changes in the measured mineral resource for KTO, KOV Open Pit and T17 Open Pit is a decrease of 1.7 million tonnes at KTO, 2.2 million tonnes at KOV Open Pit and 0.2 million tonnes at T17 Open Pit based on the depletion of the mineral resource due to mining in 2013.
    • Changes in the indicated mineral resource for KOV Open Pit is a decrease of 1.1 million tonnes based on the depletion of the mineral resource due to mining in 2013.
    • Changes in the inferred mineral resource for KOV Open Pit is a decrease of 0.3 million tonnes based on the depletion of the mineral resource due to mining in 2013.
  • There are no changes in the mineral resources reported for Mashamba East Open Pit, Kananga Mine and Tilwezembe Open Pit, as mining was not undertaken in these areas in 2013 and no geological work was done on these areas in 2013.
  • A reconciliation table comparing the 2012 and 2013 mineral resource estimates is set out in Annexure A.

Key Updates: Ore Reserves

  • The outcome of the December 31, 2013 ore reserve estimate is a net increase of 3.9 million tonnes of ore reserves, the net increase in reserve is based on completion of T17 underground Pre-feasibility study, 4.7 million tonnes being mined in 2013 and minor, short-term ore definition changes and pit design adjustments undertaken in 2013.
  • A reconciliation table comparing the 2012 and 2013 ore reserves is set out in Annexure B and the key mining parameters which inform the ore reserve estimates are set out in Annexure C

Notes:

  1. The ore reserve and mineral resource estimates have been prepared in accordance with the classification criteria of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves prepared by the Joint Ore Reserves Committee of the Australasian Institute of Mining and Metallurgy, Australian Institute of Geoscientists and Minerals Council of Australia, as amended ("JORC Code").  If the definitions and classification standards adopted by the Canadian Securities Administrators' National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") had been used instead of those of the JORC Code, the estimates of mineral reserves and mineral resources would be substantially similar to the estimates of ore reserves and mineral resources presented here.
  2. The mineral resource estimates have been prepared by, or under the supervision of, Christiano Santos Goncalves, (MAusIMM CP (Geo) 306 079) and the ore reserve estimates have been prepared by, or under the supervision of, Jacobus Lotheringen, PrEng each of Golder Associates Africa Pty Ltd, who are each a qualified person under NI 43-101.
  3. Mineral resources are inclusive of ore reserves.
  4. Mineral resources which are not ore reserves do not have demonstrated economic viability.
  5. For KTO, the ore reserve and mineral resource estimates are for KCC's entire interest in such ore reserves and mineral resources, whereas the Company owns 75% of KCC.  La Generale des Carrieres et des Mines and La Société Immobilière du Congo, state-owned mining companies in the Democratic Republic of Congo, own the remaining 25% of KCC.
  6. Numbers may not add due to rounding.
  7. Unless otherwise noted, the Company's ore reserves are estimated using appropriate cut-off grades based on an assumed long term price of $6 178 per tonne of copper and long term price of $25 062 per tonne of cobalt. Ore reserves are estimated using appropriate process recoveries, operating costs and mine plans that are unique to each property and include estimated allowances for dilution and mining recovery.
  8. Unless otherwise noted, the Company's mineral resources are estimated using appropriate lithological interpretations, grade compositing and grade estimation techniques for copper and cobalt.
  9. The Company's normal data verification procedures have been used in collecting, compiling, interpreting and processing the data used to estimate ore reserves and mineral resources. Independent data verification has not been performed. However the data has been independently validated.

Qualified Person and Technical Report
This press release was prepared under the supervision of Tim Henderson, Technical Consultant, Katanga and a 'qualified person' as such term is defined in NI 43-101. Mr. Henderson has reviewed and approved the contents of this press release.
