VANCOUVER, Jan. 10, 2019 -  Capstone Mining Corp. ("Capstone" or the "Company") (TSX:CS) releases preliminary fourth quarter and full year copper production results for 2018 and provides 2019 operating and capital expenditure guidance for its continuing operations.

2018 Production Results

Total production from continuing operations totalled 19,200 tonnes (42.3 Mlbs) and 70,400 tonnes (155.2 Mlbs) of copper in the fourth quarter and full year 2018, respectively, in line with the Company's guidance of between 67,450 to 74,550 tonnes of copper production.

Capstone will provide additional discussion and analysis regarding 2018 fourth quarter and year end production results when the Company reports its quarterly financial results on February 12, 2019, followed by a conference call on February 13, 2019 at 11:30 am ET.

2019 Operating and Capital Guidance

In 2019, Capstone expects to produce between 145 million and 160 million pounds of copper at a C1 cash cost^(1),(2) of between US$1.80 and US$2.00 per pound payable copper produced.

2019 Catalysts and Key Drivers

Pinto Valley

• Complete a scoping level study examining the potential economics of the overall reserve and resource base. As at December 31, 2017⁽⁴⁾, Pinto Valley had a Measured and Indicated Resource Estimate of over 1.35 billion tonnes grading 0.31% copper and a total Reserve Estimate of 430 million tonnes grading at 0.30% copper.
• Quarterly copper production will fluctuate throughout the year given anticipated grade variability. The average copper grade in 2019 is expected to be approximately 0.32%, with grades at 0.28% during Q2.

Cozamin

• In Q1 2019, publish an updated Technical Report with mine plan and cost estimates to reflect the increased Reserves announced on December 10, 2018⁽⁵⁾.
• Begin developing the underground haulage network from a two-way single ramp to a one-way ramp, to eliminate the production bottleneck and fill the mill to nameplate capacity. This is expected to result in an approximate 30% increase in expected throughput, to 3,780 tonnes per day by the end of 2020, increasing annual production to between 40 to 45 million pounds of copper.
• Continue greenfield exploration drilling on the Mala Noche Footwall Zone (MNFWZ) to assess open, up dip areas of the MNFWZ, northwest of the Portree Claim.

Santo Domingo Project

• Completion of the strategic process, announced in the fourth quarter of 2018⁽⁶⁾, to evaluate alternatives relating to the ownership of the Santo Domingo Project. Alternatives under review include selling a portion of the Project, as well as the potential for streaming opportunities given the gold reserve and cobalt resource to help finance the Project.
• Develop the technical and financial feasibility of producing cobalt as a by-product by conducting a preliminary economic assessment for the cobalt opportunity.
• Continue to advance the Project to be construction ready by early 2020; secure the final two long lead permits required for construction and advance project engineering to 60% to 65% completion.

Cautionary Note to United States Investors

This news release contains disclosure that has been prepared in accordance with the requirements of Canadian securities laws, which differ from the requirements of US securities laws.

US investors are cautioned not to assume that all or any part of indicated resources will ever be converted into reserves. US investors should also understand that "inferred resources" have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. It cannot be assumed that all or any part of "inferred resources" will ever be upgraded to a higher category. Therefore, US investors are also cautioned not to assume that all or any part of inferred resources exist, or that they can be mined legally or economically.
