Capstone Extends Pinto Valley Mine Life to 2039

(all amounts in US dollars)

VANCOUVER, Jan. 18, 2016 /CNW/ - Capstone Mining Corp. ("Capstone") (TSX: CS) today announced the results of the Pre-Feasibility Study – Mine Life Extension ("PV3 PFS") for its wholly owned Pinto Valley Mine in Arizona, US.

Highlights

• Proven and Probable Mineral Reserves increased to 473.8 million tonnes grading 0.31% copper, resulting in mine life to 2039, a 13 year increase over the previously published PV2 PFS (2014).
• Life of Mine ("LOM") average annual production of copper in concentrate is estimated at 122.8 million pounds of copper and 1.9 million pounds of molybdenum.
• Mill production increases to 20.4 million tonnes per year (56,000 tonnes per day ("tpd")) in 2017 from 19.8 million tonnes (54,000 tpd) in 2016 through improvements in maintenance and operational practices.
• Expected LOM C1 cash costs ⁽¹⁾ are estimated to be $2.05 per pound of payable copper (net of by-product credits and including capitalized stripping as an operating cost).
• No significant capital is required for PV3 until stripping commences in 2020.

"The PV3 PFS adds significant value to the Pinto Valley Mine by more than doubling the remaining mine life to 23 years and increasing throughput by 8% without any major capital investment," said Darren Pylot, President and CEO of Capstone.

"The PV3 mine plan and capital schedule closely mirrors the PV2 mine plan for the next two years, but with increased throughput rates. The mine plan calls for relatively higher grade in 2016 and 2017 with low sustaining capital requirements, resulting in a C1 cost, including capitalized stripping, ranging from $1.90 to $2.00 per pound of copper and an all-in cost ⁽¹⁾ ranging from $2.10 to $2.20 per pound of copper in those years," continued Mr. Pylot. "The grade profile allows us to weather the current copper price environment and the mine plan gives us significant flexibility, with the next major decision point being to advance the first PV3 pushback in 2020. Our focus will continue to be on process improvements, with significant leverage to the upside when copper prices improve."

Pre-Feasibility Study
The PV3 PFS project was directed by Capstone with contributions from Kirkham Geosystems Ltd. (geology, resource estimation), Independent Mining Consultants, Inc. (reserve, geotechnical, mine design and schedule, equipment selection), KWM Consulting Inc. (metallurgy), Amec Foster Wheeler Environment & Infrastructure, Inc. (tailings), SRK Consulting (U.S.), Inc. (environmental), and Capstone (infrastructure and financial modelling). Personnel from each of these companies will be signing off as a Qualified Person ("QP") as defined in National Instrument 43-101 Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators ("NI 43-101") for their specific responsibilities.

The Pinto Valley Mine is a conventional open pit operation, with drilling, blasting, loading and hauling. The mill operation consists of a primary, secondary, tertiary crushing system, six ball mills, and flotation concentration.

The mill produces copper and molybdenum concentrates. The PV3 PFS contemplates that mill production increases will be achieved through improved maintenance and operating practices, resulting in increased operating hours and increased hourly throughput.

Mineral Resources
The mineral resources are effective January 1, 2016. The estimate includes results from drill programs conducted in 2015 and a revised geological model.

Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Mineral Resource Estimates do not account for mineability, selectivity, mining loss and dilution. These Mineral Resource Estimates include Inferred Mineral Resources that are normally considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as Mineral Reserves. There is also no certainty that these Inferred Mineral Resources will be converted to Measured and Indicated categories through further drilling, or into Mineral Reserves, once economic considerations are applied.

Mineral Reserves
The PV3 PFS Mineral Reserve was estimated without any tailings or land boundary constraints. The study assumes that additional permits and land are available when required (see permitting section below). The Mineral Reserve was developed by tabulating the contained measured and indicated (proven and probable) material inside of the designed pit at the mill cut-off grades.

Mine Production Schedule
The increase in ore reserves will extend mining to 2038 and mineral processing to 2039, an increase of 13 years from the current mine plan of 2026. Total mine production will increase to approximately 48.5 million tonnes in 2018 through 2031 then decreasing thereafter through 2039. Life of mine strip ratio is 0.92:1.

The PV3 PFS has identified the need for additional mining equipment that will be purchased in 2019 to enter service in 2020 to move the increased waste and ore tonnages.

Processing
In the fourth quarter of 2015 mill production averaged above 54,000 tpd, up from the planned 52,000 tpd, accomplished through improvements in maintenance and operating practices. Continuation of these improvements is expected to maintain production at 54,000 tpd in 2016 and increase to 56,000 tpd in 2017. Metal recoveries average 88% for copper and 46% for molybdenum.

Payable copper and molybdenum production will average 119 million pounds and 1.8 million pounds per year through to 2039. Historically the Pinto Valley Mine has produced between 200,000 to 250,000 ounces of silver annually. Silver has not been estimated in the geological model and is not included in the Mineral Resource or Reserve estimate. As a result, silver represents potential upside to the study and has not been included in the study or estimated C1 costs. Copper cathode production will be phased out starting in 2018 due to lower production, higher operating costs and the need for waste rock storage area.

The study assumes that 80% of the concentrate will be sold internationally and 20% domestically, achieving an average concentrate shipping cost of $119/wet metric tonne. Copper concentrate terms are estimated at $95/dry metric tonne treatment and $0.095/pound refining cost with 96.5% payable copper.

Infrastructure
Pinto Valley Mine has existing mine, mill, water and power related infrastructure to support operational needs for the expanded mine life and increased mine equipment.

The tailings storage facility #4 ("TSF4") will be raised an additional 175 feet (53 metres) above the current permitted height of 800 feet (244 metres). Upgrades to the tailings pumping system will be needed and additional land will be required from the US Forest Service (see permitting section below).

Capital Cost Estimate
The total PV3 life of mine sustaining capital cost estimate is summarized below:

Operating Cost Estimate

Permitting
Extending the mine life to 2039 from 2026 will require revisions of two major permits:

• Aquifer Protection Permit ("APP") issued by the Arizona Department of Environmental Quality ("ADEQ") to expand an existing tailings facility and permit a new mine waste rock storage facility.
• An amendment to the Plan of Operations ("POO"), issued by the US Forest Service, related to:
  • Tailings storage expansion, 409 acres,
  • Mine expansion, 61 acres,
  • Outstanding permit renewals.
