VANCOUVER, British Columbia—- Capstone Mining Corp. (“Capstone” or the “Company”) (TSX:CS) announces its production and financial results for the three (“Q3 2020”) and nine months (“YTD 2020”) ended September 30, 2020. Strong copper production totaled 38.5 million pounds of copper, despite planned downtime at Pinto Valley to complete the majority of PV3 Optimization Phase 1 upgrades, at consolidated C1 cash costs¹ of $1.82 per payable pound produced. Link HERE for Capstone’s Q3 2020 management’s discussion and analysis (“MD&A”) and financial statements and HERE for the Q3 webcast presentation.

“We are two months away from the start of a high growth phase for the Company, enhanced by innovation that will see us delivering 40% more production at 20% lower costs by 2023,” said Darren Pylot, President and CEO of Capstone. “I’m proud of the strong safety and operating results we delivered in Q3 2020, with Pinto Valley carrying out Phase 1 PV3 Optimization installations and Cozamin achieving the lowest quarterly unit costs it has ever realized in its history.”

“We are seeing a pick-up of interest in Santo Domingo since we announced the MOU for rail and port facilities last month. With an increasingly positive outlook for copper, iron and cobalt, it is not surprising to see momentum like this for a fully permitted, large scale project in a mining-friendly jurisdiction,” continued Mr. Pylot.

HIGHLIGHTS AND SIGNIFICANT ITEMS

Full Year Production Guidance on Target

Year to date consolidated production of 112.5 million pounds and consolidated C1 cash cost¹ of $1.91 per pound is on track with the Company’s full year guidance of 140-155 million pounds, at C1 cash costs of $1.85-$2.00 per pound.

With improvements to copper markets during the quarter, full year 2020 capital expenditures and exploration cost estimates have been returned to levels originally guided for 2020. Full year capital and exploration costs are expected to be $90 million and $10 million respectively, which positions the Company for 20% production growth and 10% lower costs in 2021.

Cozamin Records Lowest Quarterly C1 Cash Cost¹ in Operating History

C1 cash costs¹ of $0.36 per pound produced at Cozamin is the mine’s lowest cost quarter in its operating history. During Q3 2020, the mine benefited from an optimized mine plan focused on higher copper grades (1.77%) and higher throughput (3,090 tonnes per day (“tpd”)), resulting in higher production (10.6 million pounds), higher by-product credits on strong silver prices in addition to higher silver grades (46.5 grams per tonne) and recoveries (79%), as well as lower costs from reduced operating development metres.

Strengthened Balance Sheet in Q3

Available liquidity¹ at September 30, 2020 was $136.9 million, with net debt of $163.1 million and EBITDA of $51.6 million, resulting in a net debt to EBITDA ratio of 1.62x. During the quarter, repayments of $30.0 million were made on the revolving credit facility (“RCF”) and the $26.7 million of cash advances from customers received in Q2 2020, presented as contract liabilities at June 30, 2020, were settled by delivery of copper concentrate during Q3 2020 at market prices.

Health and Safety Update

We continue to enforce rigorous COVID-19 control and prevention measures at all our operations to ensure the health and safety of our workers. Our operations were not materially affected by COVID-19 during Q3 2020. Full year consolidated guidance does not reflect any potential for additional suspensions or other significant disruption to operations or increased costs due to COVID-19. Refer to the Risk section of the MD&A for further details on COVID-19 related risks.

Zero Harm continues to be a priority at Capstone and our Q3 2020 and YTD 2020 safety performance is summarized below.

Our rolling 12-month LTIFR and TRIFR targets for 2020 are both below 2019 actual rates. In 2019, both LTIFR and TRIFR decreased from 2018 by 80% and 50%, respectively.

At Cozamin, since the completion of the 818 meter raisebore in April 2020, which was safely completed 52 days ahead of schedule and is a major component to the mine’s expansion development, air flow in the mine has increased by 22% and the overall underground temperature has dropped an average of 3.3 degrees Celsius.

Cozamin Increased Proven and Probable Mineral Reserves and Life of Mine Plan

In September 2020, the Company released the results of an updated positive technical report for Cozamin mine with updated Proven and Probable Mineral Reserves and life of mine plan (“LOMP”). Proven and Probable Mineral Reserves increased by 97% relative to December 31, 2019, to 10.2 million tonnes grading 1.79% copper. The LOMP should be considered interim as it is subject to change should the pillar extraction pre-feasibility study (“PFS”) prove positive (see Corporate Update below for more details). Refer to the National Instrument (“NI”) 43-101-compliant Technical Report filed on SEDAR on October 23, 2020 for more information.

Santo Domingo MOU with Puerto Ventanas S.A. for Rail and Port Facilities

In September 2020, Capstone announced its 70% owned subsidiary Minera Santo Domingo (“MSD”) entered a memorandum of understanding (“MOU”) with Puerto Abierto S.A. (“PASA”), a wholly owned subsidiary of Puerto Ventanas S.A. (“Puerto Ventanas”) (subsidiary of Sigdo Koppers S.A.), for the Santo Domingo project (the “Project”). During a 90 day period, both MSD and PASA will together explore mutual synergies and regional benefits for the proposed port component of the Project, Puerto Santo Domingo (the “Port”). The Port is fully permitted and located 100 kms from the Project site. The Port will be one of only two Cape-size vessel ports in the region, making it an attractive site for bulk shipments and a key asset allowing for broad resource development in Region III of Chile. The MOU also gives PASA 90 days to evaluate the replacement of the 110 km magnetite concentrate pipeline with a railway as part of its rail business, Ferrocarril del Pacifico S.A. (FEPASA).

The Santo Domingo project infrastructure that is under consideration in this MOU represents approximately $400 million of the capital expenditure identified in the most recent NI 43-101 Technical Report and includes marine works including pier, iron concentrate pipeline from Santo Domingo Mine to Port, magnetite filter plant and stockpile building, copper storage building and ship loading and support facilities. For full details, please refer to the Company’s news release of September 16, 2020.

CORPORATE UPDATE

Capstone Relaunches Sustainability Reporting

Capstone recently published an interim sustainability performance data report for specific material topics, including Governance, Health and Safety, Climate Change and Energy Emissions, Air Emissions, Water, Waste and Hazardous Materials and Employment, Diversity & Inclusion and Education, for the period January 1, 2018 to June 30, 2020. On a going-forward basis, the Company will resume publishing an annual sustainably report, with the first update expected in H1 2021 for the period January 1-December 31, 2020.

PV3 Optimization Update

In Q4 2019, Pinto Valley commenced a PV3 Optimization project designed to achieve safer, more reliable and higher capacity without major investments in new comminution equipment. A goal was set to achieve increased reliability, and higher throughput at maximized copper recovery with lower costs by leveraging new inexpensive technologies. The investment decision criteria are return-on-investment, improved safety performance and environmental stewardship.

Following is an update on the various PV3 Optimization phases and initiatives as of October 27, 2020:

• Phase 1: $17 million in crushing and mill equipment replacements which is 60% completed, with full completion expected by July 2021.
• Phase 2: $10 million in conveyor, mill auto controls, cyclone packs and tailings thickener upgrades planned to be completed by Q3 2021.
• Mine Innovation:
  • Blast fragmentation optimization to target 30% fines (minus ½”) in run of mine feed – completed Q2 2020.
  • $0.3 million Tele-remote D10 Dozer to increase worker safety for high risk applications – completed Q2 2020.
  • $6 million in new mine equipment to increase efficiency while lowering diesel consumption, GHG emissions and other operating costs by $0.8 million per year – completed Q3 2020.
• Metallurgical Innovation:
  • Pioneering novel catalytic technology developed by Jetti Resources that is expected to deliver 300 to 350 million pounds of copper cathode over the next twenty years from high grade mine waste and historic stockpiles at all-in costs under $2.00 per pound. Details will be provided in an updated NI 43-101 Technical Report expected in 2021 – commenced Q3 2020.
  • Molybdenum plant re-start: New reagents will be used to improve worker safety and improve overall metallurgical performance. Minimal capital – expected completion by Q1 2021.

Targeting higher throughput and higher copper recovery: Figure 1 shows Pinto Valley’s average daily throughput adjusted for copper recovery (i.e. throughput times recovery) over the past six years and a target by 2022-2023 to 60k to 63k tpd at 85% to 90% recovery. This is 17% to 30% higher than 2019 performance and is subject to further test work and studies to be completed in H1 2021, including tailings management.

Figure 1 – Pinto Valley Average Daily Throughput Adjusted for Copper Recovery

Pilot plant testing of new coarse particle flotation technology: Eriez Flotation Division, a wholly owned business unit of Eriez Manufacturing Co., the world leader in innovative flotation technology, has developed a fluidized bed assisted flotation cell called the HydroFloat, proven effective at floating coarse ore particles, up to two to three times the size limit of conventional flotation cells. This technology was first introduced at a commercial scale for base metal sulfides at Newcrest’s Cadia Valley operation in Australia, and very recently Newcrest has announced they are expanding the application of HydroFloat.

Following positive laboratory results on Pinto Valley flotation circuit samples, Eriez has reported an opportunity to reduce copper losses by up to 50%, thereby boosting overall recovery by up to 6%. Furthermore, the ability to recover coarse particles could allow for higher mill throughput while achieving high copper recovery. Other benefits could be lower grinding costs, lower water and energy consumption and increased tailings stability via coarser tailings. Pilot plant testing will commence in November 2020 with results expected in Q1 2021. Figure 2 below illustrates how Eriez HydroFloat could fit into Pinto Valley’s current flotation circuit and Pinto Valley’s September 2020 laboratory results.

PV4 Expansion Study Update

Work on PV4 expansion scenarios to take advantage of approximately one billion tonnes of Measured and Indicated Resources at 0.30% copper continued during Q3 2020. Given management’s confidence in PV3 Optimization progress to date, including the successful implementation of the novel catalytic technology from Jetti Resources to enhance leaching performance, Capstone has decided to evaluate expansion scenarios using existing assets rather than building new mill infrastructure. The study is assessing higher mining rates, higher cut-off grades to the mill, and an increased tonnage available for leaching. While a significant mill expansion is not currently being contemplated, an expansion of Pinto Valley’s SX-EW capacity of 25 million pounds per year may be necessary. Extensive column leach test work will be conducted over 2021, with the overall PV4 expansion study expected to be released in 2022.

Cozamin On Track for Ramp-Up to 1.35 Mtpa by Q2 2021

The development of Cozamin’s one-way ramp continues to be on schedule and on budget, expected to be completed in December 2020. Cozamin is expected to ramp-up to 1.35 million tonnes milled per annum (“tpa”) rate by Q2 2021. For the three years post-expansion (2021-2023) when compared to the three years pre-expansion (2018-2020), average annual copper and silver production increases by 70% to 61.4 million pounds and 43% to 1.75 million ounces, respectively, as described in the NI 43-101 Technical Report. Additionally, average annual C1 costs¹ (net of by-products) are expected to move 23% lower to $0.67 per payable pound of copper.

Cozamin Paste Backfill System Study

A PFS of an underground paste backfill system at Cozamin is underway to assess the potential for increasing the extraction ratio from Vein 20 in the Mala Noche Footwall Zone (“MNFWZ”). The updated LOMP currently excludes these pillars and assumes an extraction ratio of 74%, leaving 3.5 million tonnes of Indicated Mineral Resources grading 1.89% copper and 42 g/t silver in unmined pillars that will be the subject of the PFS. The 3.5 million tonnes represents over 2 years of additional mine life at 1.35 million tonnes milled per year. The pillar extraction PFS is targeted for completion in Q4 2020 with release in early Q1 2021 and assuming positive economics, it will include updated capital and net present value estimates and changes to the current LOMP.

Cozamin Announces New Step-Out Drill Program

A new step-out drill program totalling 80 holes targeting the down dip extension to the southeast of both Vein 10 and Vein 20 of the MNFWZ at Cozamin is underway. Hole S499 and S503 intersected high grade polymetallic copper, zinc, lead and silver in a 650-meter step-out from the current mineral resource. A 1 km exploration drift is being considered to provide a drilling platform to target this new area.

For full details on the above Cozamin updates, please refer to the Company’s news release of September 9, 2020.

OPERATIONAL AND FINANCIAL OVERVIEW

• Third quarter 2020 (Q3 2020) copper production of 38.5 million pounds at C1 cash costs¹ of $1.82 per payable pound of copper produced.
• Q3 2020 net income of $2.3 million, or $0.01 per share, and Q3 2020 adjusted net income¹ of $9.5 million or $0.02 per share. Adjusted net income¹ was adjusted for the non-cash share-based compensation expense of $7.5 million or $0.02 per share, driven by the mark to market adjustment for the increasing share price.
• Revenue of $130.5 million for the quarter benefited from higher sales due to a drawdown of inventory at Pinto Valley and a higher realized copper price of $3.13 per pound.
• Q3 2020 operating cash flow before changes in working capital¹ of $44.9 million or $0.11 per share.
• Q3 2020 adjusted EBITDA¹of $51.6 million and reduction in net debt to EBITDA ratio from 2.54x to 1.62x at the end of the quarter, which results in a reduction in our interest pricing in the fourth quarter of 2020 to LIBOR plus 2.75% (from LIBOR plus 3.5%). This decrease of 75 basis points results in approximately $2 million per year in annualized savings on interest expense at current debt levels.

Operational Overview

Refer to Capstone’s Q3 2020 MD&A and Financial Statements for detailed operating results.

Consolidated

Consolidated production of 38.5 and 112.5 million pounds respectively for Q3 2020 and 2020 YTD, which were slightly lower than their comparable periods of 2019 primarily due to planned downtime in July 2020 at Pinto Valley, to complete the majority of Phase 1 upgrades for PV3 Optimization and planned lower head grade. This reduction at Pinto Valley was offset by a 16% increase in production at Cozamin as a result of increased head grade, due to increased mining activities in the San Jose and Calicanto copper-rich zones.

In Q3 2020, sales were higher than production due to a drawdown of inventory at Pinto Valley.

Pinto Valley Mine

Pinto Valley’s Q3 2020 results reflect a quarter focused on advancing Phase 1 of PV3 Optimization, with planned downtime in July to install the first of two secondary crushers as well as install the first of two new ball mill shells. In addition, a planned annual outage scheduled for April was pushed to July due to COVID-19 affecting access to contractor resources. As a result of this, Ball Mill throughput for Q3 2020 was 3% lower than Q3 2019 (49,104 tpd versus. 50,630 tpd).

Copper production for the quarter was lower than in Q3 2019. The primary reason for this was due to 6% lower planned grades for Q3 2020 of 0.31% versus 0.33% for Q3 2019.

Cozamin Mine

Q3 2020 C1 cash costs¹ of $0.36 per pound is the lowest quarterly costs in Cozamin’s operating history, driven by higher head grades (1.77% versus 1.48%), higher production, lower costs from reduced operating development meters and higher by-product credits primarily on strong silver prices. In addition, silver production for Q3 2020 benefited from higher grades and higher recoveries.
