Katanga Mining Ltd announces ore reserves and mineral resources

Key Updates: Mineral Resources

• Overall, the measured and indicated mineral resource for Kamoto Copper Company SA ("KCC") (in which the Company has a 75% interest) increased by 68.5 million tonnes since December 31, 2015, consisting of the following:
  • Change in the measured mineral resource for KTO is an increase of 2.7 million tonnes due to new drilling, stope mapping, validation and incorporation of historical drillholes, and reclassification methodology resulting in an updated geological model.
  • Changes in the indicated mineral resource for KTO, KOV Open Pit and Mashamba East Open Pit is a decrease of 7.0 million tonnes at KTO, an increase of 39.1 million tonnes at KOV Open Pit and an increase of 33.8 million tonnes at Mashamba East Open Pit based on new drilling, validation and incorporation of historical drillholes, and reclassification methodology resulting in an updated geological model.
  • Changes in the inferred mineral resource for KTO, KOV Open Pit and Mashamba East Open Pit is a decrease of 0.7 million tonnes at KTO, a decrease of 12.8 million tonnes at KOV Open Pit and a decrease of 18.9 million tonnes at Mashamba East Open Pit based on new geological models being developed due to additional drilling and reclassification of resources.
    
    
• There are no changes in the measured, indicated or inferred mineral resources reported for T-17 Open Pit / T-17 Underground Mine, Kananga Mine and Tilwezembe Open Pit Mine, as no mining and no geological work was undertaken in these areas in 2016.
  
  
• A reconciliation table comparing the 2015 and 2016 mineral resource estimates is set out in

Annexure A.

Key Updates: Ore Reserves

• The result of the December 31, 2016 ore reserve estimate is a net increase of 26.2 million tonnes of ore reserves since December 31, 2015, the entirety of which increase is attributable to Mashamba East Open Pit. The net increase in ore reserves is based on an updated resource model and completion of a prefeasibility study of the Mashamba East Open Pit.
  
  
• A reconciliation table comparing the 2015 and 2016 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

Cautionary Note to US Investors concerning estimates of Measured, Indicated and Inferred Mineral Resources
The above tables use the terms "Measured, Indicated and Inferred Mineral Resources" in accordance with the ore reserves and mineral resource categories of the JORC Code. We advise US investors that while these terms are recognized and required by Canadian regulations, the US Securities and Exchange Commission does not recognize them. "Inferred mineral resources" have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of inferred mineral resources will ever be upgraded to a higher category. In accordance with Canadian rules, estimates of inferred mineral resources cannot form the basis of feasibility or other economic studies. US investors are cautioned not to assume that any part or all of the inferred mineral resource exists, or is economically or legally mineable.

Unless otherwise specified, all $ amounts referred to in this press release are U.S. dollars.

Forward Looking Statements
This press release may contain forward-looking statements, including, but not limited to, statements concerning the mineral resources and ore reserves of the company, economic feasibility thereof, and the overall expected improvement of recoveries and grades. Often, but not always, forward-looking statements can be identified by the use of words such as "plans", "expects" or "does not expect", "is expected", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates" or "does not anticipate", or "believes", or describes a "goal", or variation of such words and phrases or state that certain actions, events or results "may", "could", "would", "might" or "will" be taken, occur or be achieved.
