Overview

⁽¹⁾ The items marked with a "1" are alternative performance measures; please see "Alternative Performance Measures" at the end of this release.

"We had another solid year in 2012," said Darren Pylot, President and CEO of Capstone. "Our revenue, earnings and cash flow remained strong and we exceeded production and cost guidance for the year. Both operating mines are well-positioned to deliver on their targets in 2013."

"We are looking ahead to the growth of the company and in 2013 are reinvesting in our mines and development projects. With approximately ten year mine lives at our operating mines and additional exploration upside, Capstone is poised to deliver strong results well into the future. We plan to advance our development projects in 2013 by formally entering the permitting process at Kutcho and completing key milestones at Santo Domingo, including submitting the Environmental Impact Study and completing the Feasibility Study.  We will also continue activities on our greenfield exploration portfolio, with initial drilling campaigns at projects in Chile and Mexico," continued Mr. Pylot.

"With our strong balance sheet we have the financial resources in place to execute on our strategy. In addition, the ability to deploy our balance sheet on opportunistic acquisitions provides Capstone with the flexibility to grow our short term production profile and advance the company to the next level."

• Produced a record 46.9 million pounds of copper in concentrates during the year.
• Completed 27,114 metres of underground exploration drilling in 48 Diamond drill holes.
• Completed 4,754 metres of surface exploration drilling in 5 Diamond drill holes.
• In two separate resource updates announced in February 2012 and March 2013, the Measured and Indicated resource in Mala Noche Footwall Zone ("MNFWZ") increased to 188.6 million pounds of contained copper, which includes the MNFWZ reserves.
• Incorporated a copper reserve in the MNFWZ of 2.27 million tonnes at a grade of 1.96% copper, based on the initial resource estimate, bringing the remaining mine life at Cozamin to nine years.
• Completed 1,138 metres of development drifting on the MNFWZ, mining 107,356 tonnes of development ore an average grade 1.9% copper for the year.

Minto Mine, Yukon:

• Achieved record mill throughput in 2012, averaging 3,665 tonnes per day.
• Produced 35.9 million pounds of copper in concentrates. This was lower than 2011 due to lower grades compared with the previous year as a result of a higher proportion of stockpile material feeding the mill.
• In October 2012, the amendment to Minto's Water Use License was approved, allowing the placement of Area 2/118 tailings into the mined out Main Pit.  All necessary permits are in place to mine all identified reserves in the Area 2/118 open pit and underground mines.

The port site was chosen because of its exceptionally high availability for loading iron vessels. Formal application for the marine concession was made in March 2013.
• In connection with preparation of the FS, AMEC, NCL and Capstone personnel have completed a preliminary estimate of the development capital to build the Santo Domingo project. The capital cost is currently estimated at $1.5 to 1.8 billion, dependent on flow sheet variables and mine equipment lease/purchase options. Capstone is continuing on schedule to complete the FS by year-end.

The Policy fixes a deadline by which director nominations must be submitted to Capstone prior to any annual or special meeting of shareholders and sets forth the information that must be included in the notice to the company in order for a nominee to be eligible for election.

In the case of an annual meeting, notice to Capstone must be given no fewer than 35 nor more than 60 days prior to the date of the meeting; provided that if the meeting is to be held on a date that is fewer than 50 days after the date on which the first public announcement of the date of the meeting was made, notice may be given no later than the close of business on the 10th day following such public announcement.

In the case of a special general meeting that is not also an annual meeting, notice to the company must be made no later than the close of business on the 15th day following the day on which the first public announcement of the date of the special meeting was made.
