Q4 2023 OPERATIONAL AND FINANCIAL HIGHLIGHTS

  • Achieved production guidance2 for the year ended December 31, 2023, with consolidated copper production of 164,353 tonnes. Consolidated copper production for Q4 2023 was 44,103 tonnes at C1 cash costs1 of $2.67/lb, which consisted of 15,933 tonnes at Pinto Valley, 11,587 tonnes at Mantos Blancos, 10,019 tonnes at Mantoverde, and 6,564 tonnes at Cozamin.

  • Net loss of $19.5 million, or $(0.02) per share for Q4 2023 compared to net loss of $28.4 million, or $(0.03) per share for Q4 2022.

  • Adjusted net income attributable to shareholders1 of $10.8 million, or $0.02 per share for Q4 2023. Q4 2023 adjusted net income attributable to shareholders1 is lower than Q4 2022 adjusted net income attributable to shareholders1 of $60.4 million due to lower copper volumes sold.

  • Adjusted EBITDA1 of $88.3 million for Q4 2023 compared to $81.3 million for Q4 2022. The increase in Adjusted EBITDA1 is driven by a higher copper price of $3.69/lb compared to $3.45/lb (prior to unrealized provisional pricing adjustments), partially offset by lower copper sold (43.3 thousand tonnes in Q4 2023 versus 44.7 thousand tonnes in Q4 2022).

  • Operating cash flow before changes in working capital of $80.4 million in Q4 2023 compared to $76.1 million in Q4 2022.

  • At the Mantoverde Development Project ("MVDP"), construction of all elements required to commence commissioning activities were completed by year end 2023. MVDP will continue to systematically commission the concentrator plant with first saleable concentrate expected in Q2 2024. Project total capital remains unchanged at $870 million. Focus is on a safe, efficient and phased project commissioning and ramp-up.

  • Expected 2024 consolidated copper production growth of 25% driven by the ramp up of MVDP, resulting in 2024 guidance of 190,000 to 220,000 tonnes of copper at 17% lower C1 cash costs1 of $2.30/lb to $2.50/lb. Total 2024 sustaining and expansionary capital expenditure guidance is $275 million, plus an additional $180 million for capitalized stripping.

  • Total available liquidity1 of $352.8 million as at December 31, 2023, composed of $126.8 million of cash and short-term investments, and $226.0 million of undrawn amounts on the corporate revolving credit facility. Subsequent to year-end, the Company completed a Share Offering that will increase available liquidity through net proceeds to the Company of approximately $253 million (C$342 million).

3 Mantoverde production shown on a 100% basis.

Consolidated Production

Q4 2023 copper production of 44.1 thousand tonnes was 3% lower than Q4 2022 primarily as a result of lower oxide production at Mantos Blancos driven by lower dump throughput, grade and recoveries.

Q4 2023 C1 cash costs1 of $2.67/lb were 7% higher than $2.50/lb Q4 2022 mainly impacted by 3% lower production ($0.19/lb), partially offset by lower operational costs (-$0.02/lb).

Pinto Valley Mine

Copper production of 15.9 thousand tonnes in Q4 2023 was 6% higher than in Q4 2022. Lower mill throughput during the quarter (Q4 2023 - 53,134 tonnes per day ("tpd") versus Q4 2022 - 55,222 tpd), resulting from unplanned 97 hours of downtime, was offset by higher grades (Q4 2023 – 0.36% versus Q4 2022 - 0.32%) due to mining in the higher grade Castle Dome area of the mine. Recoveries were slightly lower compared to the same period last year (Q4 2023 - 86.5% versus Q4 2022 - 86.9%).

C1 cash costs1 of $2.36/lb in Q4 2023 were 5% lower than Q4 2022 of $2.48/lb primarily due to higher capitalized stripping (-$0.34/lb), higher gold by-product credits (-$0.21/lb) and higher production (-$0.16/lb), partially offset by increases in operating costs driven by higher contractor spend, electricity cost, ball mill liner cost and mechanical parts costs ($0.53/lb), stockpile drawdown ($0.04/lb) and higher treatment costs on higher volume of copper sold ($0.03/lb).

Mantos Blancos Mine

Q4 2023 production was 11.6 thousand tonnes, composed of 9.7 thousand tonnes from sulphide operations and 1.9 thousand tonnes of cathode from oxide operations, 18% lower than the 14.2 thousand tonnes produced in Q4 2022. The lower production was driven primarily by lower dump throughput tied to power outage and issues in leach pumping system, and lower grade and recoveries impacting cathode production. The mill throughput of 13,814 tpd in Q4 2023 was impacted by mill downtime caused by a planned repair that lasted three days and additional maintenance of the concentrator plant that lasted five days (power outage and pinion shaft bearing assessment). A plan to address the plant stability is underway that includes improved maintenance and optimization of the concentrator and the tailings system. Mantos Blancos 2024 sustaining capital guidance includes approximately $35 million to achieve sustainable nameplate operating rates. During the first half of 2024, the focus will be on receiving and installing the engineering and infrastructure upgrades in the tailings dewatering area of the plant in the second quarter. The Company expects Mantos Blancos to achieve its nameplate operating throughput rates late in the second quarter.

Combined Q4 2023 C1 cash costs1 were $2.71/lb ($2.58/lb sulphides and $3.32/lb cathodes) compared to combined C1 cash costs1 of $2.09/lb in Q4 2022, 30% higher than the same period last year mainly due to lower production ($0.48/lb), an increase in contracted services and labour costs mainly driven by unfavourable foreign exchange rate and inflation impact ($0.13/lb), spare parts spend ($0.12/lb), plant maintenance and spare parts spend ($0.18/lb), partially offset by lower key consumable prices (-$0.29/lb) (realized acid prices averaged $153/t in Q4 2023 versus $273/t in Q4 2022 and diesel price averaged $0.82/l in Q4 2023 versus $0.97/l in Q4 2022).

Mantoverde Mine

Q4 2023 copper production of 10.0 thousand tonnes was 5% lower compared to 10.5 thousand tonnes in Q4 2022. Heap recoveries were lower (64.6% in Q4 2023 versus 77.0% in Q4 2022), which was partially offset by higher dump throughput as a catch-up of September's lower throughput due to a temporary sulphuric acid supply shortage at a Chilean smelter.

Q4 2023 C1 cash costs1 were $3.68/lb, 1% higher than $3.65/lb in Q4 2022 due to an increase in contracted services, explosive consumption, spare parts spend and labour cost mainly driven by higher mine movement ($0.74/lb) and lower production (0.12/lb), partially offset by lower key consumable prices (-$0.83/lb). Realized sulphuric acid prices averaged $174/t in Q4 2023 versus $253/t in Q4 2022, whilst energy prices averaged $0.21/kWh in Q4 2023 versus $0.17/kWh in Q4 2022 and diesel price averaged $0.83/l in Q4 2023 versus $0.94/l in Q4 2022.

Cozamin Mine

Q4 2023 copper production of 6.6 thousand tonnes was 14% higher than the same period prior year mainly on higher mill throughput (3,786 tpd in Q4 2023 versus 3,430 tpd in Q4 2022). Grades were higher than the same period last year due to mining sequence (1.95% in Q4 2023 versus 1.89% in Q4 2022). Recoveries were consistent quarter over quarter.

Q4 2023 C1 cash costs1 were 26% higher than the same period last year mainly due to inflationary price increases on the main consumables, unfavourable foreign exchange rate, start of paste plant operations, which resulted in an increase in labour, contractor and cement costs, changes in mining method and additional bolting requirements ($0.51/lb) and higher treatment costs ($0.07/lb), partially offset by higher copper production (-$0.17/lb) and higher by-product credits due to higher silver prices (-$0.06/lb).

Mantoverde Development Project

Construction of all elements of the MVDP that were required to commence commissioning were completed during the fourth quarter of 2023. Commissioning activities are underway, and the Company is focused on a safe, efficient and phased project commissioning and ramp-up. MVDP is expected to enable the mine to process 231 million tonnes of copper sulphide reserves over a 20-year expected mine life, in addition to existing oxide reserves. The MVDP involves the addition of a sulphide concentrator (nominal 32,000 ore tonnes per day) and tailings storage facility, and the expansion of the existing desalination plant and other minor infrastructure.

MVDP is progressing under a lump sum turn-key engineering, procurement, and construction (EPC) contract with Ausenco Limited, a multi-national EPC management company, with broad international experience in the design and construction of copper concentrator projects of this scale in the international market. The execution plan includes a Capstone Copper owner’s team working with Ausenco during the execution phase. The contract with Ausenco includes the project commissioning and ramp-up.

Key milestones during the commissioning and ramp-up include:

  1. First ore to the primary crusher – completed in Q4 2023

  2. First ore to the grinding circuit – on track for Q1 2024

  3. First saleable concentrate – on track for Q2 2024

  4. Achievement of nameplate operating rates – expected during Q3 2024

As of December 31, 2023, cash capital spent at MVDP totaled $809 million versus the project capital estimate of $870 million.

MVDP Optimized FS and Phase II

The Company is currently analyzing the next expansion of the sulphide concentrator. Capstone has identified that the desalination plant capacity and major components of the comminution and flotation circuits of the MVDP can sustain an average annual throughput of approximately 45,000 tonnes per day (an increase of over 40% above the base case nameplate throughput capacity). Capstone continues to work with Ausenco's engineering team to develop the MVDP Optimized Feasibility Study, including evaluating the costs and timelines of debottlenecking the minor components of the plant to meet the potential increased throughput target. Completion of the optimized feasibility study is expected in the first half of 2024.

Given the above, the Mantoverde Phase II opportunity will evaluate the addition of an entire second processing line, possibly a duplication of the first line, to process some of the additional approximately 1.0 billion tonnes of resources not in reserves.

Santo Domingo Feasibility Study Update

The Company has continued updating the Feasibility Study ("FS") with contributions from third parties. Ausenco is optimizing the process configuration and updating the Technical Report to take into consideration recently produced metallurgical testwork data, updated mine plan with a lower strip ratio and a modernized milling and flotation circuit with a lower overall footprint and operating cost compared with the previous design. One of the key improvements is the definition of an iron concentration circuit that can produce two different qualities of product: a bulk 65% grade iron concentrate and a premium 67% iron concentrate. The Technical Report is expected to be delivered in the first half of 2024.

Mantoverde - Santo Domingo Cobalt Study

A district cobalt plant for Mantoverde - Santo Domingo may allow for low-cost by-product cobalt production while producing a by-product of sulphuric acid which can then be consumed internally to further significantly lower operating costs in the cathode process at Mantoverde.

The cobalt recovery process comprises a pyrite flotation step to recover cobaltiferous pyrite from MVDP tails and redirect it to the dynamic heap leach pads, which will be upgraded to a bio-leach configuration through the addition of an aeration system. The pyrite oxidizes in the leach pads and the solubilized cobalt is recovered via an ion exchange plant treating a bleed stream from the copper solvent extraction plant. The approach has been successfully demonstrated at the bench scale, and onsite piloting commenced in January 2024. Engineering has commenced for a small plant treating only Mantoverde pyrite concentrates to produce up to 1,500 tonnes per annum ("tpa") of contained cobalt. In line with this, Santo Domingo has initiated a Feasibility Study to assess, as part of the copper/iron circuit overall layout optimization being conducted by Ausenco, the optimum process configuration for the pyrite flotation and pumping transportation facilities needed to transport pyrite concentrate to Mantoverde's leach facilities.

At a combined MV-SD target of 4.5 to 6.0 thousand tpa of mined cobalt production, this would be one of the largest and lowest cost cobalt producers in the world, outside of Indonesia and the DRC.

PV District Growth Study

The company continues to review and evaluate the consolidation potential of the Pinto Valley district. Opportunities under evaluation include a potential mill expansion and increased leaching capacity supported by optimized water, heap and dump leach, and tailings infrastructure. District consolidation could unlock significant ESG opportunities and may transform our approach to create value for all stakeholders in the Globe-Miami District. Constructive discussions with key district stakeholders advanced during the quarter.

Chilean Tax Reform

In August 2023, Chile passed the Mining Royalty into law to be effective on January 1, 2024, replacing the prior Specific Tax on Mining Activity. As a change in tax law is accounted for in the period of enactment, rather than from its effective date, the Company recorded an initial deferred income tax charge and a corresponding increase to deferred income tax liabilities during Q3 2023.

The Mining Royalty contains two components, an 1% ad-valorem component on net copper revenues and a mine operating margin "(MOM") component based on rates ranging from 8% to 26%.

The Mining Royalty includes a maximum limit to the total tax burden, consisting of (1) corporate income tax, (2) Mining Royalty (both ad-valorem and MOM components) and (3) imputed withholding taxes. The Mining Royalty establishes that when the sum of the three components exceeds 46.5% of MOM, then the Mining Royalty is to be adjusted in such a way that it does not exceed the limit.

The Mining Royalty is not expected to have an impact on the Santo Domingo mine, which has 15 years of tax stability post commencement of commercial production as a result of Decree Law No. 600 ("DL 600") during which time it will remain subject to the prior Specific Tax on Mining. Furthermore, given the Company's growth projects in Chile, we do not expect to incur cash withholding taxes for several years, although, the deduction is available when calculating the cap under the new Mining Royalty.

Management and Board of Director Additions

Effective January 15, 2024, Oscar Flores joined Capstone as General Manager, Mantoverde. Previous General Manager, Pablo Asiain, will be retiring effective March 31, 2024. During this transition period, Mr. Flores and Mr. Asiain will work closely together to transfer knowledge and responsibilities to ensure operational continuity during the MVDP commissioning and ramp-up. Mr. Flores is a Mining Engineer with over 25 years of progressive experience, including past general management positions with Kinross, AMSA, Anglo American, and Codelco in Chile, along with New Gold in Mexico, Australia, and Canada.

Effective January 8, 2024, Gordon Bell joined Capstone's Board of Directors as a new Independent Director. He was most recently Vice Chairman for the Mining and Metals Group of RBC Capital Markets before his retirement from RBC Capital Markets in 2022. Previously Mr. Bell was the Global Head for RBC's Mining & Metals group, leading the expansion and growth of the firm's Mining and Metals practice domestically as well as in London, Australia and Asia. Mr. Bell has global expertise in corporate strategy, debt and equity financing, shareholder engagement, and mergers and acquisitions. He received a Bachelor of Science in Mining Engineering from Queens University in Kingston, Ontario and an MBA from Washington University in St. Louis, Missouri.

2024 Outlook

Guidance for 2024 on production, C1 cash costs1, and capital expenditures that was previously disclosed on January 24, 2024 remains unchanged. Capstone expects to produce between 190 to 220 thousand tonnes of consolidated copper in 2024, at C1 cash costs1 of $2.30 to $2.50 per payable pound of copper produced. Capstone first half (H1), second half (H2) 2024, and full year 2024 production and cost guidance are as follows:

COMPLIANCE WITH NI 43-101

Unless otherwise indicated, Capstone Copper has prepared the technical information in this document ("Technical Information") based on information contained in the technical reports, Annual Information Form and news releases (collectively the "Disclosure Documents") available under Capstone Copper’s company profile on SEDAR+ at www.sedarplus.ca. Each Disclosure Document was prepared by or under the supervision of a qualified person (a "Qualified Person") as defined in National Instrument 43-101 – Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators ("NI 43-101"). Readers are encouraged to review the full text of the Disclosure Documents which qualifies the Technical Information. Readers are advised that Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The Disclosure Documents are each intended to be read as a whole, and sections should not be read or relied upon out of context. The Technical Information is subject to the assumptions and qualifications contained in the Disclosure Documents.

Disclosure Documents include the National Instrument 43-101 compliant technical reports titled "NI 43-101 Technical Report on the Cozamin Mine, Zacatecas, Mexico" effective January 1, 2023, "NI 43-101 Technical Report on the Pinto Valley Mine, Arizona, USA" effective March 31, 2021, "Santo Domingo Project, Region III, Chile, NI 43-101 Technical Report" effective February 19, 2020, and "Mantos Blancos Mine NI 43-101 Technical Report Antofagasta / Región de Antofagasta, Chile" and "Mantoverde Mine and Mantoverde Development Project NI 43-101 Technical Report Chañaral / Región de Atacama, Chile", both effective November 29, 2021.

The disclosure of Scientific and Technical Information in this document was reviewed and approved by Clay Craig, P.Eng., Director, Mining & Strategic Planning (technical information related to Mineral Reserves at Pinto Valley and Cozamin), and Cashel Meagher, P.Geo., President and Chief Operating Officer (technical information related to project updates at Santo Domingo and Mineral Reserves and Resources at Mantos Blancos and Mantoverde) all Qualified Persons under NI 43-101.

Non-GAAP and Other Performance Measures

The Company uses certain performance measures in its analysis. These Non-GAAP performance measures are included in this document because these statistics are key performance measures that management uses to monitor performance, to assess how the Company is performing, and to plan and assess the overall effectiveness and efficiency of mining operations. These performance measures do not have a standard meaning within IFRS and, therefore, amounts presented may not be comparable to similar data presented by other mining companies. These performance measures should not be considered in isolation as a substitute for measures of performance in accordance with IFRS.

Some of these performance measures are presented in Highlights and discussed further in other sections of the document. These measures provide meaningful supplemental information regarding operating results because they exclude certain significant items that are not considered indicative of future financial trends either by nature or amount. As a result, these items are excluded for management assessment of operational performance and preparation of annual budgets. These significant items may include, but are not limited to, restructuring and asset impairment charges, individually significant gains and losses from sales of assets, share based compensation, unrealized gains or losses, and certain items outside the control of management. These items may not be non-recurring. However, excluding these items from GAAP or Non-GAAP results allows for a consistent understanding of the Company's consolidated financial performance when performing a multi-period assessment including assessing the likelihood of future results. Accordingly, these Non-GAAP financial measures may provide insight to investors and other external users of the Company's consolidated financial information.

C1 Cash Costs Per Payable Pound of Copper Produced

C1 cash costs per payable pound of copper produced is a measure reflective of operating costs per unit. C1 cash costs is calculated as cash production costs of metal produced net of by-product credits and is a key performance measure that management uses to monitor performance. Management uses this measure to assess how well the Company’s producing mines are performing and to assess overall efficiency and effectiveness of the mining operations and assumes that realized by-product prices are consistent with those prevailing during the reporting period.

All-in Sustaining Costs Per Payable Pound of Copper Produced

All-in sustaining costs per payable pound of copper produced is an extension of the C1 cash costs measure discussed above and is also a non-GAAP key performance measure that management uses to monitor performance. Management uses this measure to analyze margins achieved on existing assets while sustaining and maintaining production at current levels. Consolidated All-in sustaining costs includes sustaining capital and corporate general and administrative costs.

Net debt / Net cash

Net debt / Net cash is a non-GAAP performance measure used by the Company to assess its financial position and is composed of Long-term debt (excluding deferred financing costs and purchase price accounting ("PPA") fair value adjustments), Cost overrun facility from MMC, Cash and cash equivalents, Short-term investments, and excluding shareholder loans.

Attributable Net debt / Net cash

Attributable net debt / net cash is a non-GAAP performance measure used by the Company to assess its financial position and is calculated as net debt / net cash excluding amounts attributable to non-controlling interests.

Available Liquidity

Available liquidity is a non-GAAP performance measure used by the Company to assess its financial position and is composed of RCF credit capacity, the $520 million Mantoverde DP facility capacity, Cash and cash equivalents and Short-term investments. For clarity, Available liquidity does not include the Mantoverde $60 million cost overrun facility from MMC nor the $260 million undrawn portion of the Gold stream from Wheaton related to the Santo Domingo project as they are not available for general purposes.

Adjusted net income attributable to shareholders

Adjusted net income attributable to shareholders is a non-GAAP measure of Net (loss) income attributable to shareholders as reported, adjusted for certain types of transactions that in our judgment are not indicative of our normal operating activities or do not necessarily occur on a regular basis.

EBITDA

EBITDA is a non-GAAP measure of net (loss) income before net finance expense, tax expense, and depletion and amortization.

Adjusted EBITDA

Adjusted EBITDA is non-GAAP measure of EBITDA before the pre-tax effect of the adjustments made to net (loss) income (above) as well as certain other adjustments required under the RCF agreement in the determination of EBITDA for covenant calculation purposes.

The adjustments made to Adjusted net income attributable to shareholders and Adjusted EBITDA allow management and readers to analyze our results more clearly and understand the cash generating potential of the Company.

Sustaining Capital

Sustaining capital is expenditures to maintain existing operations and sustain production levels. A reconciliation of this non-GAAP measure to GAAP segment MPPE additions is included within the mine site sections of this document.

Expansionary Capital

Expansionary capital is expenditures to increase current or future production capacity, cash flow or earnings potential. A reconciliation of this non-GAAP measure to GAAP segment MPPE additions is included within the mine site sections of this document.

Realized copper price (per pound)

Realized price per pound is a non-GAAP ratio that is calculated using the non-GAAP measures of revenue on new shipments, revenue on prior shipments, and pricing and volume adjustments. Realized prices exclude the effects of the stream cash effects as well as TC/RCs. Management believes that measuring these prices enables investors to better understand performance based on the realized copper sales in the current and prior period.
