Overview

* Q1 2017 includes a provisional pricing adjustment of $5.2 million (2016 – negative $5.6 million) related to prior shipments, equivalent to $0.11 per pound (2016 – $(0.09) per pound) of copper sold during the quarter. ** Q1 2017 adjusted realized copper price includes the provisional pricing adjustments noted above and realized loss of $13.9 million (2016 gain – $9.6 million) equivalent to $(0.29) per pound (2016 gain - $0.16 per pound) related to copper derivative contracts exercised during the quarter.

"In the first quarter of 2017 we generated $22 million of operating cash flow despite challenging operating conditions at Pinto Valley," said Darren Pylot, President and CEO of Capstone. "All three of our mines generated positive net earnings for the quarter, supported by higher realized metal prices."

"We also recently announced a two year extension of our credit facility, to 2021, giving Capstone significant financial flexibility to meet our current and anticipated operating requirements," continued Mr. Pylot. "In addition, at current copper prices, we anticipate the continuation of operations at Minto until mid-2020 with a potential mine life extension beyond 2020."

Financial and Operational Highlights for the Quarter Ended March 31, 2017

• Net loss of $7.4 million included:
• Earnings from mining operations of $27.0 million,
• Realized copper price of $2.68 per pound
• Production costs included a $1.1 million non-cash charge related to the write-down of inventory at the Pinto Valley mine
• A commodity derivative loss of $13.9 million, comprising a realized loss of $11.6 million combined with an unrealized loss of $2.3 million,
• An income tax expense of $3.9 million.
• Operating cash flow before changes in working capital¹ of $24.2 million or $0.06 per common share.
• Working capital decreased $22.8 million to $148.3 million at March 31, 2017 from $171.1 million at December 31, 2016. Cash decreased to $109.4 million at March 31, 2017 from $130.4 million at December 31, 2016 largely as a result of a $20.0 million debt repayment made in January, 2017.
• Production of 20,230 tonnes of payable copper at a C1 cash cost¹ of $1.98 per pound of payable copper produced and fully-loaded all-in cost¹ of $2.80 per pound of payable pound copper produced.
• Revenue of $128.0 million generated primarily from the sale of 21,582 tonnes of copper.

Production and Additional Highlights for the Quarter Ended March 31, 2017

Pinto Valley Mine:

• Produced 11,300 tonnes of copper during Q1 2017 at a C1 cash cost¹ of $2.18 per pound of payable copper produced and all-in cost¹ of $2.77 per pound of payable copper produced.
• Copper production at Pinto Valley was lower quarter over quarter for a number of reasons. First, it was affected by a 7-day planned shutdown in January to complete repairs in the fine ore bins and the tailing thickener distribution system and then by considerable rain in the first quarter. Pinto Valley received five inches of rain over a two day period in late January, followed by additional rainfall in the following weeks. This rain reduced mining productivity and slowed the primary crusher intake, delaying the return to full operations from the planned shutdown. Mine plan sequencing also had to be changed to address high moisture in the bottom of the pit. Following this shutdown, the saturated fine ore placed additional stress on the primary crusher mainframe. As a result, the lower frame replacement, originally deferred from Q2 2016, was done over 11 days in late February and early March. Temporary primary crushing units allowed for production at reduced rates. Full production resumed on March 9, 2017 and since then throughput has averaged above 59,000 tonnes per day as of April 24.

Cozamin Mine:

• Produced 4,130 tonnes of copper during Q1 2017 at a C1 cash cost¹ of $1.33 per pound of payable copper produced and all-in cost¹ of $1.94 per pound of payable copper produced.
• During Q1 2017, grade and throughput both improved for the quarter, with recovery comparable to Q1 2016. This is in part due to the significant progress made in development rates since the process and contractor changes which were made in 2016.
• Subsequent to quarter end, on April 4, 2017, the precious metal streaming arrangement with Silver Wheaton Corp. expired. After this date, the full silver by-product credit is earned by Cozamin. As included in our guidance, this is expected to increase our by-product credits by approximately $0.40 per pound.

Minto Mine:

• Produced 5,520 tonnes of copper during Q1 2017 at a C1 cash cost¹ of $2.05 per pound of payable copper produced and all-in cost¹ of $2.10 per payable pound of copper produced.
• During Q1 2017, grade for the quarter was lower than originally planned due to mine plan sequencing changes. These were made to optimize the mine plan in anticipation of the extension of operations at Minto beyond 2017 and to reduce re-handling costs. As a result, more low grade, partially oxidized ore was directed to the mill causing recoveries to be slightly behind plan. This was partially offset by higher throughput.
• At current copper prices, Capstone anticipates the continuation of operations at Minto until mid-2020, subject to permitting and regulatory approvals. Capstone is also evaluating further deposits for re-inclusion into reserves, which may support additional mine life beyond 2020.

Additional highlights:

• Effective April 19, 2017, the Company amended its Senior Secured Corporate Revolving Credit Facility ("RCF") to provide for an extension to April 19, 2021 and a reduction in the credit available under the facility. The amendment:
• Extends the maturity of the Third Amended and Restated Credit Agreement from January 16, 2019 to April 19, 2021;
• Reduces the credit limit to $350 million on April 19, 2017 and requires an annual $25 million reduction on each anniversary of the facility to $275 million on April 19, 2020;
• Maintains the current pricing grid (starting at LIBOR + 2.5% and increasing to LIBOR + 3.5% based on the total leverage ratio) until March 31, 2019, after which date pricing increases to LIBOR + 3.0% (adjustable to LIBOR + 4.5% depending on the total leverage ratio); and
• Cancels the accordion feature of $60 million.

All other material terms and conditions of the existing RCF remain in place.

In addition to the amendment described above, Capstone repaid $10 million on April 19, 2017, reducing drawn debt to $298.9 million.

Operating Outlook
Capstone's 2017 production guidance for 94,000 tonnes (±5%) of copper at C1 cash cost¹ of $1.60 to $1.70 per pound of payable copper produced and All-in cost¹ of $2.15 to $2.25 per pound of payable copper produced remains unchanged. Minto and Cozamin are expected to complete the year on, or slightly above, plan and Pinto Valley is expected to attain higher run rates for the remainder of 2017 since the major planned maintenance activity was completed in the first quarter.

Conference Call and Webcast Details

The conference call replay will be available until Wednesday, May 3, 2017. The conference call audio and transcript will be available on Capstone's website within approximately 48 hours of the call at http://capstonemining.com/investors/events-and-presentations/default.aspx.
