"This past year was pivotal for Capstone with the acquisition of the Pinto Valley mine, positioning us as a leading intermediate copper producer," said Darren Pylot, President and CEO of Capstone. "In 2014 at Pinto Valley we plan to stabilize the operation, lower costs and complete the study for the second phase, which is intended to extend the mine life. At Cozamin and Minto we are focused on reducing costs and optimizing operations, and we will further advance and de-risk our Santo Domingo development project."

"Our cash flow remained strong throughout 2013 and we ended the year with over $100 million in cash and a very conservative balance sheet," continued Mr. Pylot. "Our strong financial position provides us with significant flexibility to fund our capital programs and continue to grow the company."

Financial and Production Highlights for the Year Ended December 31, 2013

• Net loss of $9.4 million or $0.02 per common share which included:
  • Earnings from mining operations of $57.1 million,
    • Realized copper price of $3.30 per pound.
  • Production costs included a $12.5 million non-cash charge related to the write-down of inventory at the Minto Mine,
  • $14.4 million non-cash charge related to the write-down of capitalized mineral property costs at Minto,
  • $15.6 million in current and deferred tax expenses.
• Adjusted net earnings(1) of $20.3 million or $0.05 per common share after making adjustments for certain non-cash and other items.
• Operating cash flow before changes in working capital(1) of $85.5 million or $0.23 per common share.
• Working capital decreased to $140.2 million at December 31, 2013 (which included $104.0 million of cash and cash equivalents) from $562.1 million at December 31, 2012, primarily as a result of closing the transaction to acquire the Pinto Valley Mine on October 11, 2013.
• Production of 109.6 million pounds of payable copper at a C1 cash cost(1) of $1.72 per pound of payable copper produced.
• Revenue of $332.0 million on the sale of 100.1 million pounds of copper, 14.7 million pounds of zinc, 2.3 million pounds of lead, 1,684,341 ounces of silver and 16,131 ounces of gold.

Operational Highlights for the Year Ended December 31, 2013

Pinto Valley Mine:

• Completed the acquisition of the Pinto Valley Mine from BHP Billiton on October 11, 2013 for a purchase price of $650.0 million less a working capital adjustment of $0.1 million.
• Produced 29.6 million pounds of copper in concentrates and 1.4 million pounds of copper cathode during 2013 (82 days of ownership) at a C1 cash cost(1) of $2.26 per pound of payable copper.

Cozamin Mine:

• Produced 45.5 million pounds of copper in concentrates at a C1 cash cost(1) of $1.18 per pound of payable copper.
• Completed 19,836 metres of underground infill/step-out exploration drilling in 33 diamond drill holes during 2013 primarily focused in the Mala Noche Footwall Zone.

Minto Mine:

• Produced 37.2 million pounds of copper in concentrates at a C1 cash cost(1)of $1.93 per pound of payable copper.
• Initial development ore released from underground during September 2013.

Santo Domingo Project:

• Work on the Feasibility study ("FS") and engineering continued, with the FS now expected to be completed in the first half of 2014.
• On October 29, 2013, Capstone formally submitted the Environmental Impact Assessment for the Santo Domingo project. This initiates the formal environmental assessment process, which is expected to take approximately 15 to 18 months.

Greenfield Exploration:

• During 2013 Capstone entered into an option agreement with Sociedad Química y Minera de Chile S.A. to earn up to 70% of Project Providencia in Region II, Chile, which is a very large under-explored land package in the world's most prolific copper jurisdiction. The initial option is on 350,000 hectares (3,500 square kilometres) and would be reduced over time to a maximum of 50,000 hectares if a joint venture is ultimately formed. Capstone is the operator of the project and may earn up to a 70% interest in the property with the right to withdraw from the project at any time.

Kutcho Project:

• Development activities at Kutcho were not significantly advanced in 2013 as Capstone focused on the acquisition of Pinto Valley. Following the successful close of the Pinto Valley transaction, Kutcho's production profile and mine life no longer fit within Capstone's growth strategy and strategic alternatives are being evaluated. Based on the intention of management to dispose of this asset, Kutcho's assets and liabilities have been classified in the December 31, 2013 audited financial statements as held for sale.

Financial and Production Highlights for the Quarter Ended December 31, 2013

In Q4 2013 the Company recorded a net loss of $20.9 million. The main contributors to the net loss were:

• Earnings from mining operations were $16.7 million, which was more than offset by the Minto mineral property write-down of $14.4 million, G&A expenses of $5.8 million, Pinto Valley transaction costs of $3.4 million, net finance expense of $3.4 million, and tax expense of $6.1 million.
• Adjusted net earnings(1) were $8.1 million or $0.02 per common share, after making adjustments for certain non-cash and other items.
• Operating cash flow before changes in working capital(1) was $24.2 million or $0.06 per share.
• Working capital decreased to $140.2 million at December 31, 2013 (which included $104.0 million of cash and cash equivalents) from $480.7 million at September 30, 2013, primarily as a result of closing the transaction to acquire the Pinto Valley Mine on October 11, 2013.
• Produced a total of 56.9 million pounds of payable copper at an estimated C1 cash cost(1) of $1.78 per pound of payable copper produced.
• Revenue of $136.8 million on the sale of 44.4 million pounds of copper, 4.3 million pounds of zinc, 0.2 million pounds of lead, 2,100 ounces of gold and 446,000 ounces of silver.

Production Outlook

Capstone's 2014 guidance for Cozamin and Minto is 38,500 tonnes (± 5%) of copper contained in concentrates at a C1 cash cost(1)of $1.85 to $1.95 per pound of payable copper, net of by-product credits and selling costs. Pinto Valley guidance will follow before the end of the first quarter.

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.
