Vancouver, British Columbia – Capstone Mining Corp. ("Capstone") (TSX: CS) today announced its financial results for the three and six months ended June 30, 2016. Operating cash flow before changes in working capital ⁽¹⁾ was $21.6 million or $0.06 per share, with a net loss of $13.4 million and an adjusted net loss of $7.5 million after adjusting for certain non-cash and non-recurring charges. Copper production for the quarter totalled 28,157 tonnes (27,200 tonnes of payable copper) at a C1 cash cost ⁽¹⁾ of $1.51 per payable pound produced with copper sales for the quarter of 22,549 tonnes at a C1 cash cost ⁽¹⁾ of $1.66 per payable pound sold.

Capstone will hold a conference call and webcast on Wednesday, July 27, 2016 at 11:30 a.m. Eastern time (8:30 a.m. Pacific time) to discuss these results; call-in details and information on associated slides are provided at the end of this release. This release should be read in conjunction with Capstone's consolidated financial statements and management's discussion and analysis ("MD&A") for the quarter ended June 30, 2016, which are available on Capstone's website at http://capstonemining.com/investors/financial-reporting/default.aspx and on SEDAR. An updated corporate presentation, including results to June 30, 2016, in addition to the Q2 2016 webcast slides, will also be available at http://capstonemining.com/investors/events-and-presentations/default.aspx.

* Q2 2016 includes a negative provisional pricing adjustment of $5.8 million (2015 – negative $0.9 million) related to prior shipments, equivalent to $(0.12) per pound (2015 – $(0.02) per pound) of copper sold during the quarter. 2016 YTD includes a negative provisional pricing adjustment of $11.5 million (2015 – negative $13.6 million) related to prior shipments, equivalent to $(0.10) per pound (2015 – ($0.15) per pound) of copper sold during the six month period. The Q2 2016 and 2016 YTD negative provisional pricing adjustments were predominantly related to assay adjustments. The Q2 2016 figure of ($5.8 million) is broken down as $0.1 million related to price adjustments and ($5.9 million) related to assay adjustments. This translates into adjustments of ($0.00) and ($0.12) respectively on a per pound sold basis. The YTD Q2 2016 figure of ($11.5 million) broken down as ($0.2 million) related to price adjustments and ($11.3 million) related to assay adjustments. This translates into adjustments of ($0.00) and ($0.10) respectively on a per pound sold basis. ** Q2 2016 Adjusted realized copper price includes the realized gain of $0.2 millionrelated to maturing forward contracts (2015 – nil). 2016 YTD Adjusted realized copper price includes the realized gain of $9.8 million related to the put contracts the Company exercised and maturing forward contracts (2015 – nil). 

"Operational performance in the second quarter was strong, with record setting production," said Darren Pylot, President and CEO of Capstone. "Costs trended down from the first quarter and our focus on operating efficiencies across the Company resulted in both C1 cash costs ⁽¹⁾ and all-in costs ⁽¹⁾ coming in better than planned."

"Operating cash flow for the quarter was $21.6 million and the short term price fixing and hedging we did earlier this year protected our financial position and liquidity through the volatile commodity price environment in the first half of the year," continued Mr. Pylot.

"Improved mill reliability and consistency at Pinto Valley has demonstrated its upside potential and Minto is set up to access the high grades at Minto North, positioning us well for strong second half performance."

Financial Highlights for the Three Months Ended June 30, 2016

• Net loss of $13.4 million or $0.03 per common share which included:
  • Earnings from mining operations of $2.8 million,
  • Production costs included a $6.4 million non-cash charge related to the write-down of inventory at Minto,
  • Share-based compensation expense of $3.1 million, driven primarily by an increase in Capstone's share price and the effect this has on the share unit liabilities,

• Working capital decreased marginally to $160.6 million at June 30, 2016 from $163.4 million at March 31, 2016. 

Financial Highlights for the Six Months Ended June 30, 2016

• Net loss of $26.2 million or $0.07 per common share which included:
  • Earnings from mining operations of $4.8 million,
  • Production costs included a $7.9 million non-cash charge related to the write-down of inventory at Minto and Pinto Valley,
  • Share-based compensation expense of $5.5 million, driven primarily by an increase in Capstone's share price and the effect this has on the share unit liabilities,
  • A gain on commodity derivatives of $3.2 million, comprising $1.7 million on new copper forward contracts and $1.5 million on $2.60 copper puts, which expired in February 2016,
  • $4.3 million in current and deferred tax expense.

Production and Additional Highlights for the Three and Six Months Ended June 30, 2016

Pinto Valley Mine:

• Produced 18,776 tonnes of copper in concentrates and cathode during Q2 2016 at a C1 cash cost ⁽¹⁾ of $1.45 per pound of payable copper produced, setting a quarterly production record.
• Produced 35,141 tonnes of copper in concentrates and cathode during 2016 YTD at a C1 cash cost ⁽¹⁾ of $1.54 per pound of payable copper produced.
• During Q2 2016, mill throughput continued above plan, setting a third consecutive quarterly record of 55,667 tonnes per day and contributing to lower costs on a per pound basis.
• With the mill operating at steady state and above plan since September 2015, the primary focus at Pinto Valley has been on optimizing operations. A consideration for any potential further increase in mill throughput is the availability of additional water. Capstone's goal is to determine the surplus water that would potentially be available to consider low-cost expansion opportunities in the range of 10% beyond the mill throughput level currently contemplated in the PV3 pre-feasibility study ("PFS").

Cozamin Mine:

• Produced 3,288 tonnes of copper in concentrates during Q2 2016 at a C1 cash cost ⁽¹⁾ of $1.52 per pound of payable copper produced.
• Produced 6,948 tonnes of copper in concentrates during 2016 YTD at a C1 cash cost ⁽¹⁾ of $1.51 per pound of payable copper produced.
• At Cozamin, production continued to be challenged by a shortfall in mine development. The mine underwent a reorganization in the quarter and a number of additional process improvements and training resources were implemented with mine development rates consistently improving.

Minto Mine:

• Produced 6,093 tonnes of copper in concentrates during Q2 2016 at a C1 cash cost ⁽¹⁾ of $1.70 per pound of payable copper produced, which excluded $0.01per pound of cost allocated to stockpile.
• Produced 10,615 tonnes of copper in concentrates during 2016 YTD at a C1 cash cost ⁽¹⁾ of $1.91 per pound of payable copper produced, which included$0.01 per pound of cost allocated from stockpile that was spent in prior periods, bringing the actual cash expended during 2016 YTD to $1.90 per pound of payable copper produced.
• Minto production was better than planned, led by strong mill throughput and recoveries. Mining continues to advance in the Minto North pit, with copper grades above 2% reaching the mill by early June, resulting in significantly higher production planned for the second half of the year. Underground mining continued through the second quarter and is planned to extend into Q3, to take advantage of high-grade underground ore.

Operating Outlook
Capstone's 2016 guidance to produce 108,000 tonnes (±5%) of copper from its Pinto Valley, Cozamin and Minto mines at a C1 cash cost ⁽¹⁾ of $1.45 to $1.55 per pound of payable copper produced, an all-in cost ⁽¹⁾ of $1.90 to $2.00 per pound of payable copper produced and a fully-loaded all-in cost ⁽¹⁾ of $2.05 to $2.15 per pound of payable copper produced remains unchanged. However, the production distribution by mine is expected to be different than originally guided, with outperformance at Pinto Valley and Minto expected to make up for an anticipated shortfall at Cozamin for the year. Pinto Valley guidance is being increased to 66,000 tonnes of copper, Minto guidance is being increased to 28,000 tonnes of copper and Cozamin guidance is being reduced to 14,000 tonnes of copper, all ±5%. Lower costs at Pinto Valley and Minto are expected to offset higher unit costs at Cozamin so consolidated cost guidance has not changed.

The conference call replay will be available until Wednesday, August 3, 2016. The conference call audio and transcript will be available on Capstone's website within 48 hours of the call at http://capstonemining.com/investors/events-and-presentations/default.aspx.
