Katanga Mining Provides Update on Major Projects, Announces 2019 Third Quarter Production Results

ZUG, SWITZERLAND, Oct. 24, 2019 -  Katanga Mining Ltd. (TSX: KAT) ("Katanga" or the "Company") today provides an update on its major projects and announces its 2019 third quarter production results at the Company's 75%-owned subsidiary Kamoto Copper Company ("KCC").

Update on Major Projects

Cobalt Projects Update
The cobalt debottlenecking projects (the "Cobalt Projects") at KCC are expected to continue throughout 2020. Commissioning of two filter presses was completed earlier in the year, while the third filter press was commissioned during Q3 2019. Commissioning of the magnesium oxide ("MgO") plant was completed earlier in the year while commissioning of the cobalt dryers concluded with additional works required due to mechanical failure during Q3 2019. 

Cobalt dryer #1 is undergoing a temporary repair which should be completed in Q4 2019. Dryer #2 is undergoing design modifications and is expected to be commissioned during Q1 2020. Once the permanent upgrade is completed on dryer #2, dryer #1 will be taken off-line to commence the upgrade.  Ramp up to full drying capacity is  targeted for mid-2020. Once full drying capacity is reached, KCC will be in a position to export the dry cobalt production, including from processing accumulated cobalt inventories.

The objective of the Cobalt Projects is to upgrade the existing cobalt plant design in order to reduce bottlenecks through modification of the precipitation, thickening, filtration, drying and bagging processes. This will align the design of the cobalt plant with the average life-of-mine cobalt production plan of 30,000 tonnes per annum. These improvements integrate with the existing WOL processing facilities at Luilu.

Acid Plant Update

The Sulphuric Acid production (Phase 1), Sulphur Dioxide production (Phase 2) and Steam Turbine Generator (Phase 3) project at KCC (the "Acid Plant"), continues to progress. All civil works have been completed for Phase 1 (Sulphuric Acid Production Plant) with Phases 2 and 3 civil works scheduled for completion in Q4 2019. Structural, mechanical, plate work, piping and electrical and instrumentation installation are progressing. Design has been completed, and some procurement items will continue into Q4 2019, but mainly relating to the Sulphur dioxide production (Phase 2) and the Steam Turbine Generator (Phase 3).

KCC has received from the Directorate for the Protection of the Mining Environment ("DPEM"), the applicable Environmental Impact Study approvals. Commissioning of the Acid Plant is scheduled to continue through H1 2020.

Production highlights during the nine months ended September 30, 2019 and Cobalt Update

Copper and Cobalt Production

Copper cathode production increased to 59,424 tonnes in Q3 2019 from 52,514 tonnes in Q2 2019.

Cobalt contained in hydroxide production increased to 4,763 tonnes in Q3 2019 from 2,607 tonnes in Q2 2019.  Of the total cobalt production in Q3 2019, 97% complied with Applicable Regulations (see below).

As previously announced in Q4 2018, KCC temporarily suspended the export and sale of cobalt due to the presence of uranium detected in the cobalt hydroxide at levels that exceeded the acceptable limit allowed for export of the product through main African ports. The low levels of radioactivity detected in the uranium to date do not present a health and safety risk.

On April 25, 2019, KCC resumed the export and sale of a limited quantity of cobalt that complies with both international and local Democratic Republic of Congo ("DRC") transport regulations with respect to the levels of uranium contained in the cobalt hydroxide (the "Applicable Regulations"). An aggregate of 97% of the cobalt hydroxide produced in Q3 2019 (97% in Q2 2019) complied with international transport regulations and was also below the acceptable limit of contained uranium allowed for export through main African ports.

KCC, together with the Company and KCC's 25% shareholder, DRC state-owned La Générale des Carrières et des Mines ("Gécamines"), has been working with the DRC government's Ministry of Mines and the Congolese Atomic Energy Agency on a long-term technical solution in the form of an ion exchange plant (the "IX Plant"). KCC has also implemented various alternative interim solutions, both operational and regulatory, resulting in the recommencement of the export and sale of a limited quantity of cobalt. The IX Plant has been approved by the boards of the Company and KCC respectively and remains as a potential long term option.

Following the authorization procedures of the IX Plant required by the 2018 Mining Code, the Ministry of Mines has requested KCC to submit a complete bankable feasibility study ("BFS") for the entire KCC project rather than a feasibility study limited to the IX Plant. Given the effectiveness of the interim solutions using phosphoric acid over the past two quarters, KCC undertook to provide a BFS for the entire KCC project by 2019 year-end, which will cover the long term IX Plant option.

Mining

Total ore mined increased to 3,561,045 tonnes in Q3 2019 from 2,458,521 tonnes in Q2 2019. Total ore mined increased to 8,327,603 tonnes in Q3 2019 YTD from 7,696,096 tonnes in Q3 2018 YTD. 

Total waste mined increased to 14,765,188 tonnes in Q3 2019 from 13,660,266 tonnes in Q2 2019. Total waste mined increased to 38,685,432 tonnes in Q3 2019 YTD from 37,146,249 tonnes in Q3 2018 YTD.           

Total contained copper increased to 112,015 tonnes in Q3 2019 from 68,731 tonnes in Q2 2019. Total contained copper increased to 248,363 tonnes in Q3 2019 YTD from 156,754 tonnes in Q3 2018 YTD.        

The increase in total material mined in the combined open pits in Q3 2019 compared to Q3 2018 related to the ramp-up of production and commissioning of the second Whole Ore Leach train in H2 2018. 

The increase in total material mined in the open pits in Q3 2019 compared to Q2 2019 reflects the increase of stockpiles ahead of the wet season and subsequent ramp-up of production in line with the optimized mine plan and EW refurbishment plan. 

The ongoing mining and stockpiling of low-grade ore and cobalt ore reflects the optimization of the long-term feed strategy. As a result of this strategy, low-grade ore and cobalt ore are currently being stockpiled and will be fed into the processing plant on a planned basis in the future.

Kamoto Concentrator

Total material milled and processed decreased to 2,467,572 tonnes in Q3 2019 from 2,574,400 tonnes in Q2 2019. Total material milled and processed increased to 7,749,087 tonnes in Q3 2019 YTD from 5,046,933 tonnes in Q3 2018 YTD.    

Total concentrate produced decreased to 52,725 tonnes in Q3 2019 from 66,828 tonnes in Q2 2019. Total concentrate produced increased to 186,839 tonnes in Q3 2019 YTD from 139,805 tonnes in Q3 2018 YTD.

Total oxide feed received at Luilu increased to 1,748,911 tonnes in Q3 2019 from 1,599,507 tonnes in Q2 2019. Total oxide feed received at Luilu increased to 5,171,237 tonnes in Q3 2019 YTD from 3,064,107 tonnes in Q3 2018 YTD.

Total contained copper in concentrate and oxide feed produced increased to 66,057 tonnes in Q3 2019 from 59,485 tonnes in Q2 2019. Total contained copper in concentrate and oxide feed produced increased to 195,359 tonnes in Q3 2019 YTD from 123,039 tonnes in Q3 2018 YTD.      

The increase in total material milled and processed in Q3 2019 compared to Q3 2018 is driven by the increase in milling capacity due to the ramp-up and optimization of CM6 and CM7, following commissioning at the end of 2018, as well as increased availability from the CM5 oxide mill.

The decrease in total material milled and processed in Q3 2019 compared to Q2 2019 is driven by the refurbishment of the EW plant.

Luilu metallurgical plant

Total copper cathode produced increased to 59,424 tonnes in Q3 2019 from 52,514 tonnes in Q2 2019. Total copper cathode produced increased to 169,114 tonnes in Q3 2019 YTD from 102,587 tonnes in Q3 2018 YTD.

Total cobalt contained in hydroxide increased to 4,763 tonnes in Q3 2019 from 2,607 tonnes in Q2 2019. Total cobalt contained in hydroxide increased to 10,881 tonnes in Q3 2019 YTD from 6,466 tonnes in Q3 2018 YTD.

The increase in Q3 2019 copper cathode and cobalt contained in hydroxide production compared to Q3 2018 was driven by a ramp-up of oxide material treatment rates at the Luilu refinery. 

The increase in copper cathode production in Q3 2019 from Q2 2019 was due to progress made on the EW refurbishment program and current efficiency improvements.

Outlook

On April 29, 2019 the Company announced that KCC had commenced a comprehensive business review targeting mining efficiencies and processing improvements as well as enhancements to product quality realizations and overhead cost reductions (the "Review").

Initial indications suggest there may be scope for margin improvements in the order of $200-250 million per annum. Further work, seeking to develop detailed implementation plans to deliver these improvements, is being undertaken, which if successful, are expected to be realizable by 2022.

To effect these improvements, KCC has created a transformation office to facilitate a 36 months turnaround plan, designed to unlock the potential of the people and assets across the site. To ensure timely project delivery, KCC has defined business priorities such as, but not limited to, improved efficiencies, maintenance, labor productivity and production quality, while decreasing the costs associated with procurement, sourcing and information technology.

These improvements are expected to materially increase the cash flow generation of KCC from 2022, when it is projected to achieve targeted life of mine average production of approximately 300kt of copper and 30kt of cobalt, resulting in a steady state copper unit cash cost of $1.65/lb, before cobalt by-product credits, and $0.75/lb after cobalt by-products revenue, net of allocable cobalt direct production and realization/selling costs of c$0.60/lb.¹

Production guidance for copper and cobalt has been moderately revised, compared to the August 2019 release, as follows:

Notwithstanding these targets, production in any given year will fluctuate as a function of numerous factors, including availability and utilization of the plant, geological and mining conditions, logistics, availability of reagents, availability of electricity, macro-economic factors such as commodity prices, input costs and geopolitical developments (including the 2018 Mining Code)
