Katanga Mining Announces 2018 Fourth Quarter and Year End Financial Results

ZUG, SWITZERLAND, Feb. 20, 2019 - Katanga Mining Ltd. (TSX: KAT) ("Katanga" or the "Company") today announces its financial results for the fourth quarter and 2018 fiscal year. Katanga's Financial Statements and Management's Discussion and Analysis ("MD&A") will be available on SEDAR, www.sedar.com.

Operating Results

The movement in revenue is due to the following price and volume factors:

• Copper revenue increased to $270.8 million in Q4 2018 from $246.3 million in Q3 2018. Copper revenue increased to $867.9 million in 2018 from $3.0 million in 2017. Cobalt revenue decreased to $73.9 million in Q4 2018 from, $181.8 million in Q3 2018. Cobalt revenue increased to $396.9 million in 2018 from $nil in 2017. The increase in copper revenue in both periods and the increase in cobalt revenue in 2018 compared to 2017 are due to the resumption of production in December 2017 following the completion of phase 1 of the whole ore leach project ("WOL Project") and the ongoing ramp-up of production in 2018. The decrease in cobalt revenue in Q4 2018 compared to Q3 2018 is due to the temporary suspension of cobalt sales.
  
  
• Included in sales is a net provisional pricing adjustment resulting from movements in the commodity price between the date of sale and the final pricing based on average prices for a specified period thereafter. At each reporting date, provisionally priced sales that have not been finalized retain an exposure to future changes in prices and are marked-to-market based on London Metal Exchange ("LME") and Metal Bulletin ("MB") forward prices. These adjustments were recorded in sales in the statement of loss and comprehensive loss and within receivables on the statement of financial position.

The movement in cost of sales and operating expenses is due to the considerations detailed in the table below:

Review of Q4 2018 Expenses

• A gross loss was incurred of $116.1 million in Q4 2018 compared to a gross profit of $59.2 million in Q3 2018. The gross loss is driven by lower revenue due to the temporary suspension of cobalt sales, increased reagent costs at the Luilu metallurgical plant and increased mine infrastructure and support costs. This was offset by an increase in copper sales in the quarter;
  
  
• Open pit mining costs increased to $37.3 million in Q4 2018 from $29.6 million in Q3 2018. The increase in open pit mining costs is due to increased maintenance activity surrounding the ongoing ramp-up of production;
  
  
• KTC processing costs increased to $28.5 million in Q4 2018 from $21.9 million in Q3 2018. KTC processing costs have increased due to the increase in total material milled and processed, in line with the optimized mine plan;
  
  
• Luilu refinery costs increased to $113.9 million in Q4 2018 from $83.3 million in Q3 2018. Luilu refinery costs have increased due to increased reagent costs and an increase in total oxide feed from KTC, in line with the optimized mine plan;
  
  
• Mine infrastructure and support costs increased to $114.5 million in Q4 2018 from $57.4 million in Q3 2018. The increase in mine infrastructure and support costs is driven by an increase in provisions relating to slow moving stock, an increase in provisions for other receivables and increased support costs for site activities following the ongoing ramp-up of production; and
  
  
• Royalties and transportation costs decreased to $54.3 million in Q4 2018 from $73.7 million in Q3 2018. Royalties and transportation costs have decreased due to the temporary suspension of cobalt sales.

Review of 2018 Full Year Expenses

• Gross profit increased to $13.4 million in 2018 from a $6.5 million gross loss in 2017. The increase in gross profit is related to the resumption of production in December 2017 following the completion of phase 1 of the WOL Project and the ongoing ramp-up of production during 2018. The gross profit in 2018 was impacted by the temporary suspension of cobalt sales, the impact of the DRC's new Mining Code adopted in January 2018 (the "New DRC Mining Code") and increased mine infrastructure and support costs;
  
  
• Income tax expense increased to $12.9 million in 2018 from $1.5 million in 2017. The increase in income tax expense is due to the minimum tax of 1% of revenues imposed under the New DRC Mining Code;
  
  
• Open pit mining costs increased to $117.0 million in 2018 from $49.5 million in 2017 (previously disclosed under operating expenses). The increase in open pit mining costs in 2018 compared to 2017 is due to the resumption of ore mining activities which were suspended during the 2017 comparative period to ensure sufficient ore availability for the WOL Project, of which, phase 1 was completed in December 2017 as well as the ongoing ramp-up of production in 2018;
  
  
• Underground mining costs increased to $51.1 million in 2018 from $28.5 million in 2017 (previously disclosed under operating expenses). The increase in underground mining costs reflects an increase in total underground material mined following the commencement of secondary development activities as well as the continuation of primary development activities in 2018;
  
  
• KTC processing costs increased to $81.3 million in 2018 from $33.0 million in 2017 (previously disclosed under operating expenses). The increase in KTC processing costs is due to the increase in total material milled and maintenance activities performed related to the resumption of production in December 2017 following the completion of phase 1 of the WOL Project and the ongoing ramp-up of production during 2018. Processing activities were largely suspended during the comparative period in 2017;
  
  
• Luilu refinery costs increased to $300.7 million in 2018 from $20.8 million in 2017 (previously disclosed under operating expenses). The increase in Luilu refinery costs is due to an increase in copper cathode and cobalt contained in hydroxide produced related to the resumption of production in December 2017 following the completion of phase 1 of the WOL Project and the on-going ramp-up of production during 2018. Processing activities were largely suspended during the comparative period in 2017;
  
  
• Change in metal stock was $(63.4 million) in 2018 and $31.8 million in 2017. The change in metal stock reflects a decrease in cost of sales during 2018 compared to 2017 due to increased volumes of ore in stockpile inventory, work in progress inventory and finished goods inventory. The increased volumes are due to the ongoing ramp-up of production in 2018. The increase in inventory was offset by a $24.3 million net realizable value adjustment on ore in stockpile inventory due to lower realized copper and cobalt prices. Ore mining and processing activities were largely suspended during the comparative period in 2017;
  
  
• Mine infrastructure and support costs increased to $283.5 million in 2018 from $193.6 million in 2017 (previously disclosed under operating expenses). The movement in mine infrastructure and support costs is due to increased site activity following the resumption of production in December 2017 and the ongoing ramp-up of production in 2018, an increase in provisions for other receivables and increased support costs for site activities following the ongoing ramp-up of production;
  
  
• Depreciation increased to $276.6 million in 2018 from $81.4 million in 2017 (previously disclosed under operating expenses). The increase in depreciation reflects the resumption of production in Q4 2017 and the ongoing ramp-up of production in 2018 which drove the application of the unit of production depreciation method against specific production assets as well as the commencement of depreciation in 2018 of phase 1 and phase 2 of the WOL Project; and
  
  
• Royalties and transportation costs increased to $201.7 million in 2018 from $3.6 million in 2017 (previously disclosed under operating expenses). The increase in royalties and transportation costs is due to increased sales of copper cathode and cobalt contained in hydroxide following the resumption of production in December 2017 and the ongoing ramp-up of production in 2018. Government royalty costs for copper and cobalt have increased to 3.5% of gross revenue from 2.5% of net revenue in 2018 due to the implementation of the New DRC Mining Code.
