Commissioning of Whole Ore Leach and resumption of production

  • On September 11, 2015, the Company announced the decision to suspend the processing of copper and cobalt during the construction of its Whole Ore Leach Project ("WOL Project"). The suspension continued through most of 2017, with copper production resuming on December 11, 2017;
  • Commissioning of phase 1 of the WOL Project was completed in November 2017 and first copper was produced on December 11, 2017; and
  • Phase 2 construction activities of the WOL Project have continued and are progressing according to the 2018 project execution plan. Full commissioning of phase 2 of the WOL Project is expected to commence in Q4 2018.

Mining

  • Mining operations continued during Q4 2017 at KOV and Mashamba East open pits with a focus on waste mining;
  • Waste mined in Q4 2017 was 11,193,159 tonnes, which was 9,040,173 tonnes (419.9%) higher than Q4 2016 due to increased waste mining activities in 2017 in preparation for the commissioning of the WOL Project;
  • Following the commissioning of phase 1 of the WOL Project and the resumption of copper production, ore mining commenced in Q4 2017: ore mined at the KOV Open Pit Mine ("KOV Open Pit") during Q4 2017 was 433,169 tonnes. The average copper grade of ore mined from KOV Open Pit was 2.18%, resulting in contained copper of 9,459 tonnes. In 2016 ore mined was 825 tonnes at KOV Open Pit and is related to incidental ore mined during waste mining; and
  • In Q4 2017, the Company did not commission any new items of fleet.

Processing

  • The total tonnes milled at KTC was 644,828 for Q4 2017, split between 481,617 tonnes of Kamoto Interim Tailings Dam ("KITD") material and 163,211 tonnes open pit ore;
  • KITD material milled for Q4 at the Kamoto Concentrator ("KTC") was 481,617 tonnes, resulting in 5,061 tonnes of contained copper (oxides & sulphides). The total tonnes of KITD material milled for the FY2017 was 1,758,890 tonnes with 14,912 tonnes of contained copper produced (oxides & sulphides). Copper contained in KITD oxide concentrate of 1,915 was sold to Mutanda Mining in Q4 2017, with 2,746 tonnes of copper contained in KITD oxide concentrate being sold to Mutanda Mining for the FY 2017. The production of KITD concentrates used for the ramp-up of operations in Q4 2017 will continue and the Company does not expect to make any further sales of concentrate in 2018;
  • Of the 163,211 tonnes of open pit ore milled, 36,740 tonnes were used to commission the milling circuit and flotation circuit at KTC. The waste component of this material was discarded as tailings;
  • Material processed by Luilu Metallurgical Plant ("Luilu") after commissioning was 140,226 tonnes, of which 126,471 was open pit ore tonnes and 13,755 was KITD oxide concentrate tonnes, which resulted in finished copper of 2,196 tonnes;
  • In Q4 2017, the Company re-commissioned the following assets at KTC:
    • B3 crusher for crushing capacity;
    • CM1, CM4, BM1 and BM3 for milling capacity; and
    • Flotation banks 801, 821, 802 and 803 for flotation capacity.
  • In Q4 2017, the Company commissioned:
    • New pump station for the hydro-mining activities at KITD, to facilitate anticipated production increase from 300tph to 500tph;
    • Core copper circuit of phase 1 WOL plant at Luilu;
    • New metallurgical accounting system; and
    • Two new pipelines from KTC and Luilu for the deposition of tailings into the Mupine tailings storage facility.
  • In Q4 2017, the Company completed the following work on the WOL Project:
    • Construction of the receiving thickener, core copper circuit CCD's, leach plant, and high grade clarifier for the first phase of WOL Project;
    • PLS & raffinate ponds for first and second phases;
    • The required modifications to the existing solvent extraction and electro winning plants for first copper production in Q4 were completed. Key services such as gland seal water, flocculant and lime plants were also installed and commissioned;
    • The fibre communication network, SCADA (Supervisory Control and Data Acquisition software used for automated control of the plant), electrical and instrumentation equipment were installed and commissioned, allowing for plant start-up in November 2017;
    • Concurrent with the construction of the WOL Project plant and infrastructure, the current Life of Mine plan has been optimized to ensure the appropriate blend will be supplied to the WOL process in order to maximize copper and cobalt recovery and to minimize operating costs per unit; and
    • Design work progressed during Q4 2017 on the acid plant, cobalt debottlenecking and cobalt dryer projects.

Outlook

  • During Q1 2018:
    • Open pit mining operations are expected to continue to feed ore to the run of mine stockpiles in accordance with the optimized ore blending strategy, and waste stripping in both KOV and Mashamba East open pits will continue;
    • Backfill and care and maintenance activities at KTO underground operations are expected to continue to ensure operational readiness for underground operations resuming in future years;
    • Phase 2 construction activities on the WOL Project to continue and are expected to progress according to the 2018 project execution plan;
    • KTC (including KITD), and Luilu are expected to ramp-up the operations to produce copper and cobalt in accordance with the ramp-up plan;
    • Execution of the acid plant, cobalt dryers and cobalt de-bottlenecking projects are expected to continue to ensure the completion of the planned project schedules;
    • Various continuous improvement initiatives relating to production enhancement and consumable inventory reduction are expected to be implemented to ensure the efficiency of operations.
