Vancouver, British Columbia – Capstone Mining Corp. ("Capstone") (TSX: CS) today provided its operating and capital expenditure guidance for 2016 along with a five year outlook. In 2016, Capstone expects to produce 108,000 tonnes (±5%) of copper from its Pinto Valley, Cozamin and Minto mines at a C1 cash cost ^(1,2) of$1.45 to $1.55 per pound of payable copper produced. Capital expenditures for 2016, including $38 million of capitalized stripping, are expected to be $80.2 million or$0.35 per pound of copper produced. Consolidated all-in cost guidance is $1.90 to $2.00 per pound of payable copper produced. The subsequent four year outlook is included to illustrate the overall trend of our existing operations, excluding any further growth through project development or acquisition.  

"In light of the current commodity price environment our 2016 guidance and five year outlook focuses on financial flexibility, while maximizing the cost efficiency of our existing operations," said Darren Pylot, Capstone President and CEO. "2016 is expected to be a strong year operationally for us as we process ore from the high grade Minto North open pit. We will further benefit from Cozamin's consistent performance and have started the year running well at Pinto Valley."

"Both our C1 cash cost and all-in cost are expected to be significantly lower in 2016, driven by higher production at each of our operations and strict capital management across the company," continued Mr. Pylot. "Our 2016 guidance reflects a number of cost reduction measures implemented and announced throughout 2015, including a reduction of our permanent workforce by 10% and full-time contractors by 5%. Additionally, moving into 2016 we have reduced corporate head office positions by 22%, budgeted a 25% reduction in general and administrative expenses and will immediately place the San Manuel Arizona Railroad Company("SMARRCO") on temporary care and maintenance."

2016 Copper Production and Cost Guidance

(1) This is alternative performance measure; please see "Alternative Performance Measures" at the end of this release. (2) C1 cash cost per pound of payable copper produced net of by-product credits and selling costs. (3) All-In cost per pound of payable copper produced is C1 cash cost plus NSR and production royalties, non-cash deferred revenue, all sustaining capital expenditures (including exploration and production-phase capitalized stripping), accretion of reclamation obligations, amortization of reclamation assets, corporate G&A, share-based compensation, greenfield exploration, pre-production capitalized stripping, PV2 and PV3 development and Santo Domingo holding costs. (4) Fully-loaded All-In Cost is All-In Cost plus interest expense and taxes.

Pinto Valley:  Throughout 2015 the mine began to see benefits from manpower reductions and cost efficiencies. C1 cash cost is expected to continue to fall as a result of increased throughput, declining input costs and targeted cost reduction activities which are continuing at the operation.

A key cost reduction initiative in 2016 is the temporary cessation of all rail operations as part of the transportation chain that delivers concentrate to the Port of Guaymas, Mexico for export. A modular truck transport system for both domestic consumption in the United States as well as to Guaymas for export will be used to haul the concentrate. SMARRCO will be placed on temporary care and maintenance, resulting in the furlough of 13 employees.

Cozamin:  The focus in 2016 will be on cost reduction and operational efficiencies. The majority of the ore will continue to come from the San Roberto blocks in 2016, with the Mala Noche Footwall Zone contributing approximately 30% of ore production in 2016.

Minto:  The 2016 production and operating costs at Minto reflect the significant contribution from the high grade Minto North open pit. Head grade is expected to average 1.3% in the first quarter, ramping up to over 2.6% in the second half of the year, resulting in significantly lower costs. Surface mining of the Minto North pit is expected to be completed in August 2016, with the mill continuing to process Minto North material until the end of Q1 2017.

Underground mining will be paused in Q1 2016 and the operation will be temporarily closed once all the ore from Minto North and the remaining stockpiles are processed by mid-2017. Future decisions will depend on a number of factors, most notably an improvement in the copper market outlook.

Copper Production and Costs 2017 to 2020:  Consolidated production from 2017 to 2020 is expected to average between 70,000 and 85,000 tonnes of copper annually at a consolidated C1 cash cost ranging from $1.60 to $1.70 per pound of copper.

2016 Capital Expenditure Guidance – Operating Mines (US$M)

* Capitalized stripping is included as an operating cost in the PV2 PFS and PV3 PFS, however, under IFRS accounting guidelines stripping costs are capitalized when the strip ratio is higher than the life-of-mine strip ratio.

Pinto Valley:  The largest category of sustaining capital in 2016 is $10.3 million for mining fleet component replacement, which was accounted for as an operating cost prior to 2016 and in the PV2 PFS. In 2016 this has been reclassified from operating to capital and is accounted for as capital in the PV3 PFS.

Cozamin:  Major capital expenditures in 2016 are $6.2 million for mine development and $3.5 million for the construction of a paste fill plant that was deferred from 2015.

Minto:  Limited sustaining capital is required at Minto with the expected temporary closure in 2017.

Capital Expenditures 2017 to 2020:  Beyond 2016 sustaining, development and brownfield exploration capital expenditures at our operating mines are expected to average $40 to $50 million annually (excluding capitalized stripping). Capitalized stripping at Pinto Valley from 2017 to 2020 is expected to range between $15 and $30 million annually.

2016 Exploration Program (US$M)

* Exploration is expected to be expensed for Project Providencia.

Brownfield Exploration:  At Cozamin, the 2016 exploration program includes 10,400 metres of primarily underground infill and step-out drilling aimed at increasing reserves, primarily in the Mala Noche Vein and Mala Noche Footwall Zone.

Greenfield Exploration:  In 2016 greenfield exploration is principally focused on Project Providencia in Chile, Capstone's earn-in project with Sociedad Química yMinera de Chile S.A. ("SQM"), with a continuation of the geophysics, geochemistry and drill programs that began in 2014. There is no minimum expenditure commitment in 2016 under the SQM agreement and as exploration activities are discretionary, we will align our expenditures with prevailing market conditions, financing capacity and corporate priorities.

The guidance represents the base case 2016 exploration program, which includes advancing towards scoping level resource estimates on two of the three copper discoveries at Project Providencia since 2014, along with commencing basic metallurgical studies. One deposit is a completely oxidized Chilean Stratabound Type and the other is a deeply oxidized IOCG Type. In both cases mineralization is at or very near surface, covered by very shallow overburden. Drilling in 2016 will focus on the near surface copper oxide potential.

Cautionary Note to United States Investors

This news release contains disclosure that has been prepared in accordance with the requirements of Canadian securities laws, which differ from the requirements of U.S. securities laws. Without limiting the foregoing, this news release may refer to technical reports that use the terms "indicated" and "inferred" resources. U.S. investors are cautioned that, while such terms are recognized and required by Canadian securities laws, the SEC does not recognize them. Under U.S. standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. U.S. investors are cautioned not to assume that all or any part of indicated resources will ever be converted into reserves. U.S. investors should also understand that "inferred resources" have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. It cannot be assumed that all or any part of "inferred resources" will ever be upgraded to a higher category. Therefore, U.S. investors are also cautioned not to assume that all or any part of inferred resources exist, or that they can be mined legally or economically. Accordingly, information concerning descriptions of mineralization and resources contained in this news release may not be comparable to information made public by U.S. companies subject to the reporting and disclosure requirements of the SEC.
