Lundin Mining Second Quarter Results

Toronto, July 26, 2017 (TSX: LUN; OMX: LUMI) Lundin Mining Corporation (�Lundin Mining� or the �Company�) today reported cash flows of $179.2 million generated from operations in its second quarter of the year, with net earnings from continuing operations attributable to Lundin Mining shareholders of $49.0 million ($0.07 per share) for the quarter ended June 30, 2017.

Mr. Paul Conibear, President and CEO commented, �Our operations delivered another quarter of strong aggregate performance including excellent production from Candelaria and Eagle that surpassed plan. Copper production guidance has been updated and tightened, and nickel production and cash cost guidance improved. All growth projects are on schedule and budget including the Neves-Corvo Zinc Expansion Project which recently received preliminary Environmental Impact Assessment approval following a timely and efficient review process with Portuguese authorities. 

We remain focused on value creation through disciplined investment in our existing assets and potential external acquisition initiatives. As part of a multi-year reinvestment program at Candelaria we have increased the sustaining capital expenditure program this year to purchase new and larger equipment aimed at improving operating capacity, efficiency, and profitability, and to bring forward underground development in support of planned near term production increases. Further, on success, we have increased our Company-wide 2017 exploration budget to $75 million in support of expanded near-mine programs.�   

    Summary financial results for the quarter and year-to-date:

1. Operating earnings is a non-GAAP measure defined as sales, less operating costs (excluding depreciation) and general and administrative costs.

2. Attributable to shareholders of Lundin Mining Corporation. 

3. Basic and diluted earnings / (loss) per share attributable to shareholders of Lundin Mining Corporation.

Highlights

Operational Performance

Overall production for the second quarter of 2017 was consistent with expectations, with excellent copper production from Candelaria in the quarter making up for lower production from Neves-Corvo. Nickel and zinc production were less than that realized in the second quarter of 2016, but remain in-line with expectations and full year guidance. Cash costs¹ for the quarter are consistent with or lower than those realized in the second quarter of 2016, benefitting from higher by-product metal prices.  

Candelaria (80% owned): The Candelaria operations produced, on a 100% basis, 52,846 tonnes of copper, approximately 30,000 ounces of gold and 540,000 ounces of silver in concentrate during the quarter. Copper production for the quarter was slightly higher than expectations and the prior year comparable period due primarily to higher grades and recoveries. Copper cash costs of $1.08/lb for the quarter were lower than the prior year and are expected to meet guidance over the full year.  

Construction of the Los Diques tailings dam facility continues on schedule and on budget. Total forecast spend on the project remains unchanged at $295 million, of which approximately $115 million remains to be spent as of June 30, 2017, $85 million in the second half of 2017 and $30 million in 2018.      

Eagle (100% owned): Eagle had another strong quarter of production, exceeding expectations by generating 5,822 tonnes of nickel and 5,674 tonnes of copper. Amounts were less than the same period in 2016 as a result of planned lower head grades. Nickel cash costs of $1.02/lb for the quarter benefited from higher by-product sales than the comparable period in the prior year. 

The Eagle East ramp is advancing ahead of schedule with formal amendment permit approval, for the mining of Eagle East, expected prior to year-end. 

Neves-Corvo (100% owned): Neves-Corvo produced 8,098 tonnes of copper and 18,011 tonnes of zinc in the quarter. Zinc production was consistent with the prior year comparable period, while copper production was lower due to lower throughput and grades. Copper cash costs of $1.38/lb for the quarter remain significantly lower than the prior year comparable period and full year guidance, aided by higher by-product zinc prices. 

The Zinc Expansion Project (�ZEP�) investment to double zinc production at Neves-Corvo was approved by the Company�s Board during the quarter. Underground material handling development for ZEP commenced and environmental permitting is advancing according to plan. Project activities were highlighted by the receipt of preliminary Environmental Impact Assessment approval on July 6, 2017 from Portuguese authorities.

Zinkgruvan (100% owned): Zinc and lead production in the second quarter of 2017 was consistent with the mine plan and overall guidance expectations. Zinc production, aided by higher throughput, exceeded the prior year comparable period, while lower lead grades in the current period negatively impacted its production. Cash costs for zinc of $0.34/lb for the quarter were consistent with the prior year comparable period and below full year guidance.

During the quarter, the 1350 Project, a process plant investment increasing production capacity by 10%, was successfully commissioned, on schedule and on budget. 

1. Cash cost/lb of copper, zinc and nickel are non-GAAP measures defined as all cash costs directly attributable to mining operations, less royalties and by-product credits.

Outlook

Production, cash cost, capital expenditure and exploration guidance for 2017 have been updated from that disclosed in our Management�s Discussion and Analysis for the three months ended March 31, 2017. 

2017 Production and Cost Guidance 

2017 Capital Expenditure and Exploration Guidance 

Capital expenditures, excluding capitalized interest, are expected to be $490 million (prior guidance $390 million), as outlined below.

The Los Diques tailings project remains on schedule and the project�s overall capital cost forecast remains unchanged, although the expected timing of certain payments have resulted in $15 million of expenditures expected in 2018 that will now be paid in 2017. 

Following expansion of Mineral Reserves and life of mine plans, previously announced production level increases, cost restraint driven deferrals in purchases of mobile equipment in 2015 and 2016 and commencement of an initiative to self-perform some underground mining currently done by contractor, management has undergone an intensive review of Candelaria�s mobile equipment and identified a number of areas where operating capacity, efficiency and profitability could be improved with the purchase of new additional and larger equipment. As part of this multi-year re-investment program, $45 million is expected to be spent in 2017.

In addition, $10 million in capital infrastructure has been brought forward to further develop Candelaria�s underground mines and provide access to new sectors, ensuring ore access in support of near term increased underground mine production plans. 

Neves-Corvo�s �260 million Zinc Expansion Project was approved by the Board in the second quarter of 2017, with $30 million expected to be spent in 2017. 

Exploration spend is expected to increase to $75 million, from $65 million previously guided, in support of expanded near mine exploration programs.
