Lundin Mining Announces Updated Mine Plan at Candelaria

July 29, 2015

TORONTO, ONTARIO–(Marketwired - July 29, 2015) - Lundin Mining Corporation (TSX:LUN)(OMX:LUMI) (“Lundin” or the “Company”) is pleased to report that it has completed an updated mine plan and annual sustaining capital cost estimate for Candelaria. The new plan is expected to result in an improved production and operating cost profile over the next four year period, as compared to the mine plan that was summarized in the October 6, 2014 NI 43-101 Technical Report entitled Technical Report for the Compan╠âía Minera Candelaria and Compan╠âía Minera Ojos del Salado Copper Projects, Atacama Province, Region III, Chile (“Previous Mine Plan”).

Key highlights of the updated mine plan (100% basis) include:

  • Annual total copper production for 2016-2019 is now expected to average 154 kt (compared to an average of 122 kt in the Previous Mine Plan over the same period).
  • The increased metal production is the result of optimisation of the phasing in the open pit and extended mine lives of all of the higher grade underground mines which replace lower grade Work-in-Progress stockpile material in the plant feed.
  • Weighted average annual cash costs (after incorporating the precious metal stream and capitalized waste stripping) for the period 2016-2019 are now expected to average $1.67/lb Cu, based on a Chilean Peso: US$ exchange rate of 625 : 1.
  • The new capital cost profile includes updated capital estimates for the Los Diques tailings management facility, as well as capitalized waste stripping forecasts.

Commenting on the updated Mine Plan, Mr. Paul Conibear, President and CEO of Lundin Mining stated, “We are very pleased with the results of the updated mine plan. These refinements have added significant value at Candelaria and we remain very excited about the prospect of continuing to create additional value through our ongoing exploration program and further optimization efforts.”

A summary of the updated mine plan until 2019 is shown in Table 1 below.

Total Capital Costs $ M 211 336 166 185
Total Exploration Costs $ M 32 32 25 25
(1) 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.

A National Instrument 43-101 (“NI 43-101”) Technical Report for the updated mine plan will be filed within 45 days on SEDAR ( and on the Company’s website ( The Company intends to publish updated Mineral Resources and Mineral Reserves for Candelaria in support of the new mine plan as part of the Company’s Annual Mineral Resource & Reserve statement which is expected in September. The new mine plan and Mineral Reserve statement will be ratified by the Candelaria and Ojos management committees at the next meeting.
