Katanga Mining Provides an Update on Major Projects and Announces 2019 Fourth Quarter Production Results

2020-02-04 / @newswire

 

ZUG, Switzerland, Feb. 3, 2020 /CNW/ - Katanga Mining Limited (TSX: KAT) ("Katanga" or the "Company") today provides an update on its major projects and announces its 2019 fourth quarter production results at its 75%-owned subsidiary Kamoto Copper Company ("KCC").

Update on Major Projects as at December 2019

Cobalt Projects

The cobalt debottlenecking projects (the "Cobalt Projects") continued to progress the final components of this project. The temporary repairs of cobalt dryer #1 was completed in Q4 2019. Dryer #2 is undergoing modifications and is expected to be commissioned during Q1 2020, following which, dryer #1 will be taken off-line for modification which is planned to be completed at the end of Q1 2020. Ramp up to full drying capacity is targeted for mid-2020.

Acid Plant Projects

The sulphuric acid, sulphur dioxide and steam turbine generator projects (the "Acid Plant"), continues to progress towards targeted commissioning during H1 2020.

Production highlights during the twelve months ended December 31, 2019

Copper and Cobalt Production

Copper cathode production increased to 65,402 tonnes in Q4 2019 from 59,424 tonnes in Q3 2019.

Cobalt contained in hydroxide production increased to 6,173 tonnes in Q4 2019 from 4,763 tonnes in Q3 2019.

As previously announced, KCC temporarily suspended the export and sale of cobalt due to the presence of uranium detected in the cobalt hydroxide at levels that exceed 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").

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"). In line with a long-term solution and further technical development, Whole Ore Leach ("WOL") modeling has been completed which indicates that both current and 'elevated' Uranium levels may be successfully removed from the cobalt hydroxide product with KCC's Phosphoric acid addition capabilities. KCC is however continuing to evaluate the feasibility of an IX Plant.

*

These segments include classification of ore volumes into different categories, being primary copper
containing ore, low-grade copper containing ore (but still above cut-off grade) and cobalt containing ore
(that contains copper under the copper cut-off grade but cobalt over the cobalt cut-off grade). The primary
ore component is defined as having a Cu grade of greater than 1.25% and the low-grade component is defined
as having a Cu grade between 0.65% and 1.25%. The cobalt ore component is defined as having a Cu grade of
less than 0.65% and Co grade greater than 0.30%

**

Excludes any ore hydro-mined out of Kamoto Interim Tailings Dam ("KITD") as this is not a traditional mining
operation, but a hydro-mining reclamation project

Underground waste is excluded

 

Total ore mined decreased to 3,231,048 tonnes in Q4 2019 from 3,561,044 tonnes in Q3 2019. Total ore mined increased to 11,558,652 tonnes in 2019 from 10,167,727 tonnes in 2018.

Total waste mined decreased to 9,883,967 tonnes in Q4 2019 from 14,765,188 tonnes in Q3 2019. Total waste mined decreased to 48,569,399 tonnes in 2019 from 50,981,685 tonnes in 2018.

Total contained copper decreased to 92,821 tonnes in Q4 2019 from 112,015 tonnes in Q3 2019. Total contained copper increased to 341,206 tonnes in 2019 from 218,147 tonnes in 2018.

The decrease in total material mined in the open pits in 2019 compared to 2018 relates to ongoing optimization of the mine plan.

The decrease in total material mined in the combined open pits in Q4 2019 compared to Q3 2019 reflects the start of the wet season. The wet season is accounted for in KCC's mine planning process and the results are in line with production forecasts.

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

Total oxide feed received at Luilu decreased to 1,688,262 tonnes in Q4 2019 from 1,748,911 tonnes in Q3 2019. Total oxide feed received at Luilu increased to 6,859,499 tonnes in 2019 from 4,666,773 tonnes in 2018.

Total contained copper in concentrate and oxide feed produced increased to 74,024 tonnes in Q4 2019 from 66,057 tonnes in Q3 2019. Total contained copper in concentrate and oxide feed produced increased to 269,383 tonnes in 2019 from 182,566 tonnes in 2018.

The increase in total material milled and processed in 2019 compared to 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 of the CM5 oxide mill.

The decrease in total material milled and processed in Q4 2019 compared to Q3 2019 was driven by the objective of reducing overall acid consumption by increasing copper feed grades and reducing the oxide feed tonnage.

Total copper cathode produced increased to 65,402 tonnes in Q4 2019 from 59,424 tonnes in Q3 2019. Total copper cathode produced increased to 234,516 tonnes in 2019 from 152,357 tonnes in 2018.

Total cobalt contained in hydroxide increased to 6,173 tonnes in Q4 2019 from 4,763 tonnes in Q3 2019. Total cobalt contained in hydroxide increased to 17,054 tonnes in 2019 from 11,112 tonnes in 2018.

The increase in Q4 2019 copper cathode and cobalt contained in hydroxide production compared to Q4 2018 was driven by a ramp-up of oxide material treatment rates at the Luilu refinery.

The increase in copper cathode production in Q4 2019 from Q3 2019 was due to progress made on the electrowinning ("EW") refurbishment program and current efficiency improvements as well as maintaining high ore feed rates and copper grades to Luilu refinery.

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").

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 progressively by 2022.

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. KCC has commenced executing key cost reduction initiatives identified in the transformation review process.

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 300ktonnes of copper and 30ktonnes 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-product revenue, net of allocable cobalt direct production and realization/selling costs of approximately $0.60/lb. Realization costs are based on an assumed copper price of $6,500/t and realized cobalt price of $15/lb.

Production guidance for copper and cobalt is as follows:

Notes:


(1)

Annual copper production guidance is subject to +/- 15 ktonnes variation

(2)

Annual cobalt production guidance is subject to +/- 2 ktonnes variation

 

It should be noted that production in any given year will fluctuate as a function of numerous factors, including the availability and utilization of plant and equipment, 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).
