“Last quarter we saw outperformance at both operations delivering operating cash flow of $67 million, which marks the beginning of very strong financial metrics across the business, moving forward in this current $4.00 copper price environment,” said Darren Pylot, President and CEO of Capstone. “Now that the silver stream is closed, we are in a net cash position and are on track to be debt free in 2021, allowing cash flow to be deployed to high-impact, high-return projects like paste backfill at Cozamin and Eriez HydroFloat coarse particle flotation at Pinto Valley. The pathway to financing Santo Domingo is progressing well with advanced discussions on a port deal, a gold stream and a strategic partnership.”

HIGHLIGHTS AND SIGNIFICANT ITEMS

Results Exceed 2020 Production and Cost Guidance

Capstone exceeded both production and cost guidance for 2020; finishing the year at 156.9 million pounds of copper production above the guidance range of 140 to 155 million pounds, at consolidated C1 cash costs¹ of $1.84 per payable pound of copper, below the guidance range of $1.85 to $2.00 per pound.

Cozamin 50% Silver Stream Results in Net Cash¹ Position

In December 2020, the Company announced a Cozamin Silver Stream Agreement with Wheaton Precious Metals Corp. (“Wheaton”), effective December 1, 2020. On February 19, 2021, the Company announced all conditions to complete the Stream Agreement have been fulfilled and Capstone has received $150 million from Wheaton for 50% of the silver production until 10 million ounces have been delivered, thereafter dropping to 33% of silver production, for the life of mine. On closing, the Company was in a net cash¹ position of $25 million, based on the year end net debt¹ balance of $124.9 million.

PV3 Optimization Phase 1 Delivers 10% Sustainable Throughput Improvement Compared to 2019

PV3 Optimization kicked off in 2020 with Phase 1 work completed in 2020. Phase 1 work included improved blast fragmentation processes, installation of a new secondary crushers and screen decks as well as a new mill shell. Pinto Valley achieved throughput of 57,168 tonnes per day (“tpd”) in Q4 2020, showing a 10% sustainable improvement compared to annual 2019 (averaged 51,137 tpd). December 2020 mill throughput achieved 60,717 tpd which represents a new monthly record in the mine’s operating history.

Phase 2 of the PV3 Optimization is expected to be completed in H2 2021, upon completion of upgrades to a conveyor, mill auto controls, cyclone packs and retrofits to the thickeners.

Eriez HydroFloat Coarse Particle Flotation Technology

During the month of December, a pilot plant test of Eriez HydroFloat coarse particle technology at Pinto Valley surpassed expectations of a 6% improvement target to overall copper recovery, showing a 6 to 8% increase in overall copper recovery is achievable, which when combined with expected higher throughput rates could result in an additional 9 to 12 million pounds of copper production per year. Additional benefits to the technology include allowing the operation increased throughput by operating at a coarser grind size, which is expected to lower power costs, improve water consumption and lead to improved stability in the tailings storage facility. The estimated $70 million expansionary capital, which includes the installation of Eriez HydroFloat and related equipment, if approved by the Board of Directors, is expected to be spread over H2 2021 and early 2022, with start-up expected in Q2 2022.

The Company expects to release an updated NI 43-101 Technical Report that encompasses PV3 Optimization Phase 1 and Phase 2 projects and improvements in H2 2021.

PV4 Study

Feasibility work on scenarios to take advantage of approximately one billion tonnes of Mineral Resource, not currently in the Mineral Reserve mine plan, which is at similar grade to the current Mineral Reserves will be conducted for Pinto Valley. The PV4 study is expected to be released in late 2022 and will contemplate utilizing existing mill infrastructure rather than building new, with higher mining rates, higher cut-off grades to the mill and increased tonnage available for leaching. Extensive column leach test work in collaboration with Jetti Resources LLC will take place over 2021. Jetti’s novel patented catalytic technology allows for the efficient and effective heap and stockpile leach extraction of copper and has been a success at Pinto Valley’s leaching operation, where we expect to recover up to 350 million pounds of cathode copper over the next two decades from historic and new mineralized waste piles. Capstone is a pioneer in the application of this leach technology and we intend to use it to enhance the economics of a future expansion at Pinto Valley.

Cozamin On Track for Ramp-Up to 3,780 Tonnes Per Day by End of Q1 2021

Ramp-up of mill processing to 3,780 tpd by the end of Q1 2021 is on track. The Calicanto ramp to open the one-way traffic circuit to debottleneck the mine was completed ahead of schedule in early December 2020, without any safety incidents and on budget.

Cozamin Updated Life of Mine Plan (“LOMP”) and Updated Resources

The results of an updated NI 43-101 Technical Report for the Cozamin mine were announced on January 27, 2021, including an updated life of mine plan to 2031. Full operating years (2021-2030) and the highest copper grade years (2021-2027) are summarized below:

The results announced in January 2021 also included an increase to estimated Mineral Reserves (at October 31, 2020 effective date) of 39% to 14.1 million tonnes, relative to April 30, 2020 Mineral Reserves; contained copper and silver increased by 37% and 49%, respectively. Approximately half of this increase is due to recovery of high-grade pillars using paste backfill. The Technical Report included a pre-feasibility study for an underground paste backfill system, indicating a capital cost estimate ranging from $41 million to $45 million which includes capital for the filtered (dry stack) tailings facility noted below. The plant is expected to be commissioned in Q4 2022 with full ramp up by Q1 2023, with $13 million included in 2021 capital guidance.

Cozamin intends to convert from the current slurry tailings facility that has been safely operated for over 15 years to a filtered (dry stack) tailings facility. Feasibility-level design of the filtered tailings facility is expected to be completed in Q1 2021, and preparations are being made to submit the required permit applications. It is expected that this conversion to filtered tailings will significantly decrease the mine’s socio-environmental, geotechnical and water supply risks, while decreasing water consumption and make-up water costs. The planned paste backfill system will use tailings for paste production, greatly decreasing the volume of tailings requiring an above ground storage impoundment.

Cozamin Exploration

Exploration expansion potential at the Mala Noche Footwall Zone (“MNFWZ”) remains open in both the West and the East. 2021 brownfield exploration guidance of $5 million for 40,000 meters of surface drilling will primarily target expansion drilling in the newly recognized West target area, see Figures 1 and 2. Additional infill drilling to upgrade resources in the down-dip southeast area of Vein 20, and initial testing of new brownfield targets on adjacent vein systems, many with historical production, all within the Cozamin claim block will also be completed.

The MNFWZ West target is an extension of Vein 20 recently identified by an extensive review of historical drilling data and confirmed by initial drill testing of the concept in 2020. The West target is supported by a reinterpretation of the geology in this area and has easy access from both the Mala Noche Vein (“MNV”) and MNFWZ infrastructure. Development capacity in 2021 is limited to driving one non-production drift and therefore the East exploration drift has been delayed to 2022. Development of the new West exploration crosscuts will commence in Q1 2021, in tandem with the surface drilling program, with an estimated cost of $1.8 million additional to the drilling program. Once completed, future drilling will shift to underground starting in 2022.

Santo Domingo – Exclusive Discussions with Puerto Ventanas for the Port and Rail

In September 2020, Capstone announced it had entered into 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 PASA to evaluate acquiring, constructing and operating the proposed port component of the Santo Domingo project and to evaluate replacement of the proposed 110 km magnetite pipeline with a railway. Exclusive negotiations around a proposed economic offer and framework agreement have been extended and are ongoing and we expect to provide an update later in Q1 2021. In addition to a port and rail deal with Puerto Ventanas, a gold stream and a strategic partnership are key deliverables for Capstone during 2021.

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

OPERATIONAL AND FINANCIAL OVERVIEW

• Strong fourth quarter 2020 (“Q4 2020”) copper production of 44.4 million pounds at C1 cash costs¹ of $1.68 per payable pound of copper produced. Copper sales were 39.3 million pounds at a realized copper price of $3.64 per pound.
• $150 million streaming agreement with Wheaton Precious Metals for 50% of silver at Cozamin to strengthen the balance sheet announced in December 2020 and closed February 19, 2021.
• Q4 2020 net income of $27.6 million, or $0.07 per share and Q4 2020 adjusted net income¹ of $35.6 million or $0.09 per share. Adjusted net income¹ includes positive adjustment of $10.8 million for stock based compensation expense net of tax.
• Q4 2020 adjusted EBITDA¹ of $63.5 million which is 287% higher than Q4 2019 adjusted EBITDA¹ of $16.4 million. The adjusted EBITDA¹ is reflective of strong operational performance and the leverage of the Company’s EBITDA¹ in a higher copper price environment.
• Q4 2020 operating cash flow before changes in working capital¹ of $65.3 million or $0.16 per share compared to $20.3 million or $0.05 per share in Q4 2019.

Operational Overview

Refer to Capstone’s Q4 2020 MD&A and Financial Statements for detailed operating results.

² Sales from continuing operations has been utilized due to the Minto mine being classified as a discontinued operation in the comparative period until the point of its sale on June 3, 2019.

Consolidated

Q4 2020 production was 25% higher than Q4 2019 primarily due to significantly higher production at Pinto Valley, due to higher throughput as a result of the PV3 Optimization Phase 1 projects completed in Q3 2020, and also due to an increase in production at Cozamin as a result of higher head grades. The increase in production was the primary driver for the 15% or ~$0.30/lb reduction in C1 cash costs¹.

Pinto Valley Mine

Q4 2020 production increased by 31% compared to the same period last year. PV3 Optimization Phase 1 projects completed in Q3 2020, including the implementation of improved blast fragmentation processes, installation of a new secondary crusher and screen decks as well as a new mill shell, resulted in higher throughput (Q4 2020 – 57,168 tpd, and December 2020 of 60,717 tpd), which represented the highest quarterly figure since 2017 and highest monthly figure in the mine’s operating history. Mine sequencing also contributed to higher planned head grades for Q4 2020 (0.33% versus 0.30% in Q4 2019). The higher than planned production in the month of December 2020 resulted in a build-up of inventory at December 31, 2020 and is the primary driver for why sales were lower than production for Q4 2020 and 2020 YTD.

Cozamin Mine

Production in Q4 2020 was 10% higher than the same period last year. This was primarily due to an increase in copper grade (1.72% versus 1.53%) as a result of increased mining activity from the copper rich San Jose and Calicanto zones in Q4 2020 (during Q4 2019 more material was mined from the San Rafael zinc zone which resulted in lowered blended copper grades).

Financial Overview

Refer to Capstone’s Q4 2020 MD&A and Financial Statements for detailed financial results.

² In accordance with IFRS 5, Minto’s results are excluded from revenue but included within cash flow amounts in the comparative period. The Minto mine was sold on June 3, 2019.
³ Certain prior period amounts have been restated to conform with current period classification.
⁴ EBITDA¹ is earnings before interest, taxes, depletion and amortization.
⁵ Effective January 1, 2019 the Company adopted IFRS 16 Leases (“IFRS 16”) using the modified retrospective method which applies the standard prospectively, and as such, figures above related to 2018 have not been restated to conform to IFRS 16. Refer to the Accounting Changes section of the MD&A for more information.
