"This past year was a transitional one for Capstone as we integrated Pinto Valley into our organization and completed the first full year of operation under our ownership. The trend of reducing cash cost and a final fourth quarter C1 cash cost of $1.82 per pound at that operation underscore the progress we have made so far," said Darren Pylot, President and CEO of Capstone. "The significant operating cash flow we generated in 2014 of $199.4 million also demonstrates the substantial potential of all of our operations."

"At the same time we continue to manage our business and growth opportunities in a prudent manner. The need to maintain a disciplined and flexible approach became particularly evident in the first part of 2015, when copper prices dropped to a 5-1/2 year low," continued Mr. Pylot. "Through 2015, we will remain focussed on maintaining flexibility in both our operating model and financial position so that we can quickly adapt to market conditions as required."

Operational Highlights for the Quarter and Year Ended December 31, 2014

Pinto Valley Mine:

• Produced 14,606 tonnes of copper in concentrates and 617 tonnes of copper cathode during Q4 2014 at a C1 cash cost^[1]of $1.82 per pound of payable copper produced.
• Produced 62,716 tonnes of copper in concentrates and 2,413 tonnes of copper cathode during 2014 at a C1 cash cost^[1]of $2.03 per pound of payable copper produced.
• Completedthe Pinto Valley Phase 2 Pre-Feasibility study ("PV2 PFS") in March 2014, extending the mine life at Pinto Valley to 2026, at an average annual production of 54,200 tonnes of copper in concentrate and 2,900 tonnes of copper cathode, at a Life of Mine ("LOM") C1 cash cost^[1]of $2.00 per pound of payable copper.
• Work is ongoing related to the implementation of improvements identified by the PV2 PFS, with the project execution plan in place, orders for themajority of the mine equipment placed and detailed engineering and construction underway.
• Completed an internal scoping study in 2014 that evaluated the resources at Pinto Valley not included in the current mine plan. As a result, two cases will be advanced to the Pre-Feasibility study level ("PV3 PFS"). The PV3 PFS base case will include a 10% to 15% increase in throughput and the possibility of a mine life extension beyond 2026 and a second case will evaluate a throughput increase to 90,000 tonnes per day combined with a potential mine life extension. The PV3 PFS is expected to be completed in the third quarter of 2015, at which time we will evaluate the two alternatives and the best use of capital.

Cozamin Mine:

• Produced 4,573 tonnes of copper in concentrates during Q4 2014at a C1 cash cost^[1]of $1.30 per pound of payable copperproduced.
• Produced 19,813 tonnes of copper in concentrates during 2014 at a C1 cash cost^[1]of $1.26 per pound of payable copperproduced.
• Exploration drilling from surface to test structural splays off of the main Mala Noche vein system continued throughout 2014.
• During 2014 Capstone acquired 45 mining concessions covering 770 hectares situated along strike and surrounding current Capstone claims, giving Capstone control of the majority of the Mala Noche vein system and many of its subsidiary splays both along strike and at depth.

Minto Mine:

• Produced 3,299 tonnes of copper in concentrates during Q4 2014 at a C1 cash cost^[1]of $2.94 per pound of payable copperproduced.
• Produced 18,411 tonnes of copper in concentrates during 2014 at a C1 cash cost^[1]of $2.33 per pound of payable copperproduced.
• Surface mining was suspended at the end of Q3 2014 due to delays in receipt of the Water Use License ("WUL") Amendment, which is required to permit pre-stripping at Minto North. Fresh ore from underground mining was supplemented with stockpiled ore to feed the mill in Q4 2014. On February 6, 2015, the Yukon Water Board requested additional information after the public comment period closed.Minto responded to this Information Request on February 16.As a result, we do not expect that the Minto North deposit will be stripped as planned at the beginning of Q2 2015. We will continue to work with the Yukon Water Board to secure the required WUL Amendment as expeditiously as possible, but will not be making any commitment of capital until an acceptable permit is received. Copper prices are currently at levels where the economics of the Minto Mine, without the Minto North deposit, are questionable. We are evaluating all options for optimizing the cash flows from Minto in the current market climate.

Santo Domingo Project:

• The Company completed the tender process for Engineering, Procurement, Construction ("EPC") and Engineering, Procurement, Construction Management ("EPCM") packages for project development.Capstone has selected POSCO E&C ("POSCO") as the preferred EPC fixed price lump sum contractor for the Santo Domingo project. While the EPC contract has not been negotiated or concluded, Capstone has awarded a Limited Notice to Proceed to the end of Stage-Gate 1,which will includeconfirmationofcompleteness of the engineering andcontractualperformanceguaranteeparameters. This award totals approximately $4.5 million and is part of Capstone's previously announced 2015 base case budget of $16.9 million (of which Capstone's 70% share is $11.8 million). This work is expected to be completed before the end of Q2 2015. Following Stage-Gate 1, next steps will be determined and communicated. The total capital cost of the project is expected to be at or below the previously estimated $1.7 billion.
• On January 27, 2015, the third information request from the authorities was received. Under the current timetable the Environmental Impact Assessment is now expected to be received during Q2 2015, which aligns with the revised engineering development plan outlined above.
• A third party objection to the Santo Domingo port concession application was rejected by the Chilean Armed Forces, clearing the way for the anticipated approval of the application in Q1 2015.

Greenfield Exploration:

• Exploration work at Project Providencia in Region II, Chile during 2014 included extensive soil and rock geochemical surveys, geological mapping, several different Induced Polarization surveys, and drilling. Eight different prospect areas were identified for their potential to host copper gold mineralization of porphyry-type and IOCG and Manto type mineralization.
• Exploration work during Q4 2014 at Project Providencia included drilling of 7,036 metres over 25 holes.

Corporate:

• Subsequent to year-end, Capstone entered into an amended senior secured corporate revolving credit facility ("RCF") for up to $500-million. This facility amends Capstone's existing senior secured corporate revolving term facility and allowed for the repayment and cancellation of the existing senior secured reducing revolving credit facility.
• The RCF comprises a committed $440-million plus a $60-million accordion. It has a four-year term maturing in January, 2019 (with extension rights on mutual consent), an interest rate of US LIBOR plus 3.0% (adjustable in certain circumstances) and a standby fee of 0.675%, payable on the undrawn balance of the facility. The $60-million accordion may be exercised by Capstone once additional credit is committed from existing and/or new lenders.

Financial and Production Highlights for the Quarter Ended December 31, 2014

In Q4 2014 the Company recorded a net loss of $34.4 million. The main contributors to the net loss were:

• Non-cash charges of $32.3 million relating toa write down of inventory ($11.4 million) and capitalized mineral property costs ($9.9 million) at Minto and the impairment of available-for-sale securities ($11.0 million).
• A reduction in realized copper price from $3.30 per pound in Q4 2013 to $2.79 per pound in Q4 2014, a decrease of 15%
• Adjusted EBITDA^[1]was $40.6 million or $0.11 per common share after making adjustments for certain non-cash and other items.
• Operating cash flow before changes in working capital^[1]was $30.7 million or $0.08 per share.
• Working capital decreased to $106.5 million at December 31, 2014 from $139.9 million at December 31, 2013.
• Produced a total of 22,282 tonnes of payable copper at an estimated C1 cash cost^[1]of $1.88 per pound of payable copper produced.
• Revenue of $142.0 million generated primarily from the sale of 23,751 tonnes of payable copper.

Production Outlook

Capstone's 2015 guidance for 90,000 tonnes 5% of copper in concentrates, at a C1 cash cost^[1]of $2.00 to $2.10 per pound of payable copper, net of by-product credits and selling costs, remains unchanged.
