Overview

* Q4 2016 includes a negative provisional pricing adjustment of $0.1 million (2015 – negative $4.2 million) related to prior shipments, equivalent to $0.00 per pound (2015 – $(0.09) per pound) of copper sold during the quarter. YTD includes a negative provisional pricing adjustment of $12.7 million (2015 – negative $25.8 million) related to prior shipments, equivalent to $(0.05) per pound (2015 – $(0.13) per pound) of copper sold during the year. ** Q4 2016 adjusted realized copper price includes the provisional pricing adjustments noted above and realized loss of $8.5 million (2015 gain – $10.1 million) equivalent to $(0.13) per pound (2015 gain – $0.21 per pound) related to copper derivative contracts exercised during the quarter. YTD includes a realized gain of $3.3 million (2015 – $15.9 million) equivalent to $0.01 per pound (2015 – $0.08 per pound) related to copper derivative contracts exercised during the year.

"Our strong operating performance in 2016 exceeded guidance, setting records at Pinto Valley, Minto and for Capstone as a whole," said Darren Pylot, President and CEO of Capstone. "All three of our mines generated positive net earnings, with throughput success at Pinto Valley and processing of high grade Minto North ore being key drivers in 2016."

"Despite a challenging copper price environment for most of the year, we generated operating cash flow of $156.9 million, allowing us to reduce our debt by $40 million," continued Mr. Pylot. "We anticipate taking full advantage of additional free cash flow to further reduce our debt over the coming quarters."

"Our year end results included a non-cash write-down of our Santo Domingo project based on lower forecast iron prices," continued Mr. Pylot. "The project does however, continue to have considerable optionality in a rising market."

Production and Additional Highlights 
Pinto Valley Mine:

• Produced 17,051 tonnes of copper during Q4 2016 at a C1 cash cost¹ of $1.70 per pound of payable copper produced and all-in cost¹ of $2.06 per pound of payable copper produced.
• Produced 68,850 tonnes of copper during 2016 at a C1 cash cost¹ of $1.61 per pound of payable copper produced and all-in cost¹of $1.95 per pound of payable copper produced.
• Copper production at Pinto Valley exceeded expectations, with mill throughput and head grade above plan for the quarter and year. Throughput averaged 56,800 tonnes per day ("tpd") and 56,200 tpd for the fourth quarter and full year, respectively. The operation continued to demonstrate the mine's potential, achieving a new daily throughput record of over 64,000 tpd in December.

Cozamin Mine:

• Produced 4,001 tonnes of copper during Q4 2016 at a C1 cash cost¹ of $1.40 per pound of payable copper produced and all-in cost¹ of $2.06 per pound of payable copper produced.
• Produced 14,307 tonnes of copper during 2016 at a C1 cash cost¹ of $1.48 per pound of payable copper produced and all-in cost¹ of $1.88 per pound of payable copper produced.
• During 2016, Cozamin experienced a mine development shortfall resulting in lower production, however, during the second half of the year Cozamin conducted a management reorganization and a number of additional processes were implemented to improve the development rates. Development rates continued to improve through the second half of the year (7,725 meters H2 2016 vs. 5,880 meters H1 2016).
• During Q4 2016, Cozamin achieved the revised target production due to a better than planned average head grade of 1.63% copper offset by lower than planned mill throughput.

Minto Mine:

• Produced 8,801 tonnes of copper during Q4 2016 at a C1 cash cost¹ of $0.33 per pound of payable copper produced, which included $0.11 per pound of cost allocated from stockpile that was spent in prior periods, bringing the actual cash expended during Q4 2016 to $0.22 per pound of payable copper produced and all-in cost¹of $0.43 per payable pound of copper produced.
• Produced 31,426 tonnes of copper during 2016 at a C1 cash cost¹ of $1.03 per pound of payable copper produced, which included $0.03 per pound of cost allocated from stockpile that was spent in prior periods, bringing the actual cash expended during 2016 to $1.00 per pound of payable copper produced and all-in cost¹of $1.12 per payable pound of copper produced.
• Copper production for the quarter met expectations while full year throughput, grade and recoveries all exceeded plan. In the fourth quarter the mill processed stockpiles, supplemented by underground mining.
• Produced 39,506 ounces of gold contained in copper concentrate, and 11,675 ounces of gold contained in gold concentrate, for a total of 51,181 ounces produced during 2016. Under the terms of the Precious Metal Stream Agreement with Silver Wheaton, Capstone receives market rates for 50% of gold produced in excess of 30,000 ounces in a twelve-month period. We exceeded this threshold during Q4 and as a result Capstone is entitled to sell 8,320 ounces of gold at market rates. 5,100 of these ounces were sold in Q4 2016 and the remaining 3,220 ounces are expected to be sold in H1 2017.

Additional highlights:

• On January 13, 2017 a second repayment of $20.0 million was made on the RCF, reducing the outstanding balance to $308.9 million. At the same time, Capstone chose to permanently reduce the credit available under the RCF from $420 million to $400 million. This payment was in addition to a $20.0 millionpayment and permanent credit reduction made in Q4 2016. The combination of this lower commitment and the strong debt coverage ratio at December 31, 2016 resulted in the Company achieving the second lowest tier on the RCF pricing grid with interest rates of LIBOR plus 2.75% and stand-by fees of 0.6188%. This will result in annualized savings of almost $1.5 million per year in interest and stand-by fees.
• As a result of the decline in long term iron ore prices during 2016, Capstone recorded an impairment on the Santo Domingo development Copper/Iron project of$189.2 million during Q4 2016.

Operating Outlook
Capstone's 2017 production guidance is for 94,000 tonnes (±5%) of copper at a C1 Cash Cost¹ of $1.60 to $1.70, All-In Cost¹ of $2.15 to $2.25 and Fully-Loaded All-In Cost¹ of $2.20 to $2.30, per pound of payable copper produced net of by-product and selling costs.

Capital Outlook
Capstone's 2017 capital expenditures are expected to be $67 million, with $35 million for sustaining capital at Pinto Valley and Cozamin, $2 million related to PV3 permitting activities and $30 million for capitalized stripping at Pinto Valley. An additional $10 million is budgeted for both brownfield and greenfield exploration, however as exploration activities are discretionary they will be aligned with prevailing market conditions, financing capacity and corporate priorities.
