Cautionary Statements Caution Regarding Forward-Looking Information and Non-GAAP Performance Measures This presentation contains forward-looking information, including, but not limited to, guidance on estimated annual production and cash costs. This forward-looking information is not based on historical facts, but rather on current expectations and projections about future events and is subject to risks and uncertainties. Any statements not including historical facts are forwardlooking statements and may be identified by terminology such as believe, budget, continue, can, estimate, expect, intend, likely, should, target, will and any similar expressions. Forward-looking statements involve known and unknown risks and uncertainties, and as such, they are not guarantees of future performance. Actual results may differ materially from those projected in the forward-looking statements. Potential risks leading to differing results include, without limitation: fluctuation to foreign currency rates, change in commodity prices, industry risks, drilling results, labour disputes or difficulties resulting in labour shortages or interruptions in production, environmental risks, political risks including changes in national or local government legislation, taxation, or regulation, climate and weather related risks, diminishing quantities or grades of reserves, operating or technical difficulties with mining or development activities, and increased costs, delays or suspensions. Readers are cautioned that many of the assumptions on which the Company s forward-looking statements are based are likely to change. Lundin cautions that it does not have any intention to update forward-looking statements as a result of new information, future changes, or otherwise. For further details of other risks and uncertainties see Risk Factors Relating to the Company s Business in the Company s Annual Information Form and Management s Discussion and Analysis. This presentation contains certain financial measures such as operating earnings, net debt, operating cash flow per share and cash costs which have no meaning within generally accepted accounting principles under IFRS and therefore amounts presented may not be comparable to similar data presented by other mining companies. This data is intended to provide additional information and should not be considered in isolation or as a substitute for measures or performance prepared in accordance with IFRS. Note: All dollar amounts are in US dollars unless otherwise denoted. 2

2016 Second Quarter Operating Highlights Operations continued to perform well and position us to meet or exceed full-year guidance on metal production, capital spending, and cash costs All mines were cash flow positive during the quarter contributing to additional balance sheet strength Copper (Cu) Nickel (Ni) Zinc (Zn) Copper production guidance is increased to reflect above plan production, primarily on greater throughput at Candelaria Full year cash costs at Neves-Corvo and Candelaria are lowered given results to date and on-going success of cost saving programs Strong nickel production at Eagle due to improved head grades and plant recoveries Neves-Corvo zinc plant operations exceeded expectations year-todate with stable throughput and good zinc recoveries Zinc production at Zinkgruvan was lower in Q2 due to processing copper ore on both lines to reduce a large stockpile 4

Production guidance is based on certain estimates and assumptions, including but not limited to; mineral resources and reserves, geological formations, grade and continuity of deposits and metallurgical characteristics. 2. Cash costs remain dependent upon exchange rates (forecast at /USD:1.15, USD/SEK:8.30, USD/CLP:690) and metal prices (forecast at Cu: $2.10/lb, Ni: $4.00/lb, Zn: $0.80/lb, Pb: $0.75/lb, Au: $1,150/oz, Ag: $15.00/oz, Co: $11.00/lb).

Excludes capitalized interest. Amounts forecast above are on a cash basis, and may vary from accruals based estimates. 2. During the production phase, waste stripping costs which provide probable future economic benefits and improved access to the orebody are capitalized to mineral properties. The Company capitalizes waste costs when experienced strip ratios are above the average planned strip ratio for each open pit phase under development. 8
