Notes:

1.

The ore reserve and mineral resource estimates have been prepared in accordance with the classification criteria of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves prepared by the Joint Ore Reserves Committee of the Australasian Institute of Mining and Metallurgy, Australian Institute of Geoscientists and Minerals Council of Australia, as amended ("JORC Code").  If the definitions and classification standards adopted by the Canadian Securities Administrators' National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") had been used instead of those of the JORC Code, the estimates of mineral reserves and mineral resources would be substantially similar to the estimates of ore reserves and mineral resources presented here.

2.

The mineral resource estimates have been prepared by, or under the supervision of, Christiano Santos Goncalves, (MAusIMM CP (Geo) 306 079) and the ore reserve estimates have been prepared by, or under the supervision of, Jacobus Lotheringen, PrEng each of Golder Associates Africa Pty Ltd, who are each a qualified person under NI 43-101. 

3.

Mineral resources are inclusive of ore reserves.

4.

Mineral resources which are not ore reserves do not have demonstrated economic viability.

5.

For KTO, the ore reserve and mineral resource estimates are for KCC's entire interest in such ore reserves and mineral resources, whereas the Company owns 75% of KCC.  La Generale des Carrieres et des Mines and La Société Immobilière du Congo, state-owned mining companies in the Democratic Republic of Congo, own the remaining 25% of KCC. 

6.

Numbers may not add due to rounding.

7.

Unless otherwise noted, the Company's ore reserves are estimated using appropriate cut-off grades based on an assumed long term price of $6,309 per tonne of copper and long term price of $26,720 per tonne of cobalt. Ore reserves are estimated using appropriate process recoveries, operating costs and mine plans that are unique to each property and include estimated allowances for dilution and mining recovery.

8.

Unless otherwise noted, the Company's mineral resources are estimated using appropriate lithological interpretations, grade compositing and grade estimation techniques for copper and cobalt.

9.

The Company's normal data verification procedures have been used in collecting, compiling, interpreting and processing the data used to estimate ore reserves and mineral resources. Independent data verification has not been performed. However the data has been independently validated.

Qualified Person and Technical Report
This press release was prepared under the supervision of Tim Henderson, Technical Consultant, Katanga and a 'qualified person' as such term is defined in NI 43-101. Mr. Henderson has reviewed and approved the contents of this press release.

Cautionary Note to US Investors concerning estimates of Measured, Indicated and Inferred Mineral Resources
The above tables uses the terms "Measured, Indicated and Inferred Mineral Resources" using 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.

Forward Looking Statements
This press release may contain forward-looking statements, including, but not limited to, the suspension of copper and cobalt processing, reductions in headcount and contractor demobilization process, the impact of newly acquired or commissioned equipment on operations, the ongoing development of T17 Underground Mine, the improvements related to the Whole Ore Leach Project, the expectation of resumption of production and the impact of the timing 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.

All forward-looking statements reflect the Company's beliefs and assumptions based on information available at the time the statements were made. Actual results or events may differ from those predicted in these forward-looking statements. All of the Company's forward-looking statements are qualified by the assumptions that are stated or inherent in such forward-looking statements, including the assumptions listed below. Although the Company believes that these assumptions are reasonable, this list is not exhaustive of factors that may affect any of the forward-looking statements. The key assumptions that have been made in connection with the forward-looking statements include the following: the operations of the Company during the production suspension and timeline for the recommencement of operations remaining consistent with management's expectations, there being no significant disruptions affecting the operations of the Company whether due to labour disruptions, supply disruptions, power disruptions, rollout of new equipment, damage to equipment or otherwise; permitting, development, operations, expansion and acquisitions at the Project being consistent with the Company's current expectations; continued recognition of the Company's mining concessions and other assets, rights, titles and interests in the DRC; political and legal developments in the DRC being consistent with its current expectations; the continued provision or procurement of additional funding from Glencore for operations, the completion of the T17 Underground Mine, the WOL Project and the Power Project; the successful completion of, and realizing the intended benefits from the WOL Project and the Power Project; new equipment performs to expectations; the successful development of the T17 Underground Mine; the exchange rate between the US dollar, South African rand, British pounds, Canadian dollar, Swiss franc, Congolese franc and Euro being approximately consistent with current levels; certain price assumptions for copper and cobalt; prices for diesel, natural gas, fuel oil, electricity and other key supplies being approximately consistent with current levels; production and cost of sales forecasts for the Company meeting expectations; the accuracy of the current ore reserve and mineral resource estimates of the Company (including but not limited to ore tonnage and ore grade estimates); and labour and material costs increasing on a basis consistent with the Company's current expectations.

Forward-looking statements involve known and unknown risks, future events, conditions, uncertainties and other factors which may cause the actual results, performance or achievements to be materially different from any future results, prediction, projection, forecast, performance or achievements expressed or implied by the forward-looking statements. Such factors include, among others, the actual results of current exploration activities; actual results and interpretation of current reclamation activities; conclusions of economic evaluations; changes in project parameters as plans continue to be refined; future prices of copper and cobalt; possible variations in ore grade or recovery rates; failure of plant, equipment or processes to operate as anticipated; accidents, labour disputes and other risks of the mining industry; delays in obtaining governmental approvals or financing or in the completion of exploration, development or construction activities, delays due to strikes or other work stoppage, both internal and external to the Company as well as those factors disclosed in the Company's current annual information form and other publicly filed documents. Although Katanga has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements.

The Company disclaims any intention or obligation to update or revise any forward-looking statements whether as a result of new information, future events, or otherwise, except in accordance with applicable securities laws.
