VANCOUVER, British Columbia--BUSINESS WIRE--
Capstone Copper Corp. (“Capstone” or the “Company”) (TSX:CS) (ASX:CSC) today announced the results of a feasibility study (“FS”) for its Mantoverde Optimized brownfield expansion project (“MV Optimized” or “MV-O”).
John MacKenzie, Capstone’s Chief Executive Officer, commented, “We are excited to release the results of our MV Optimized Feasibility Study which, when combined with our recently released Santo Domingo Feasibility Study, defines the next phase of transformational growth for Capstone. MV Optimized is a capital efficient, high return and low risk expansion project that is expected to bring on an additional 20,000 tonnes per annum of copper for approximately $146 million of capital. We see the MV-SD district producing approximately 250,000 tonnes of copper per annum, placing it amongst the largest producing copper districts in the world, with very attractive unit cash costs. Between MV Optimized and Santo Domingo, we expect to have significant optionality to surface further value, including through exploration drilling which has not been performed at Mantoverde since 2019. Our team is committed to pursuing the highest standards in safety and environmental management as well as continued engagement with all stakeholders as we progress our growth plans. The ramp up of the current Mantoverde Development Project continues to progress well and I am thrilled that the plant achieved commercial production in September.”
MANTOVERDE OPERATION SUMMARY
Mantoverde (70%-owned by Capstone Copper and 30%-owned by Mitsubishi Materials Corporation) is an open-pit copper-gold mine located in the Atacama region of Chile. Since the 1990s, Mantoverde operated as an oxide mine producing copper cathodes from its 60,000 tonnes per annum capacity SX-EW plant. Last year in 2023, Capstone Copper completed construction of the Mantoverde Development Project (“MVDP”) that enabled the mine to process its copper sulphide reserves, in addition to existing oxide reserves. The MVDP involved the addition of a sulphide concentrator (nominal 32,000 ore tonnes per day (“tpd”)) and tailings storage facility, and the expansion of the existing desalination plant and other minor infrastructure. First saleable copper concentrate at MVDP was produced in June 2024 and commercial production was achieved in September 2024. Commercial production is defined as the achievement of reaching a minimum of 30 consecutive days of operations during which the mill operated at an average of 75% of nameplate throughput of 32,000 tpd.
MANTOVERDE OPTIMIZED FEASIBILITY STUDY
MV OPTIMIZED HIGHLIGHTS
- MV Optimized is a capital efficient debottlenecking expansion of the existing sulphide concentrator from throughput of 32 ktpd to 45 ktpd
-
An extended 25-year mine life is supported by a higher sulphide Mineral Reserve1 estimate of 398 million tonnes at a copper grade of 0.49% and a gold grade of 0.10 grams per tonne
- Sulphide Mineral Reserve tonnes have increased by 68% while contained copper has increased by 40%
-
The updated oxide Mineral Reserve2 estimate is 236 million tonnes at a soluble copper grade of 0.21%
- Oxide Mineral Reserve tonnes have increased by 18% while contained copper has increased by 11%
- Expansionary capital of $146 million yields total incremental production of 368,000 tonnes of copper and 215,000 ounces of gold compared to the previous technical report, reflecting a capital intensity of approximately $7,500 per tonne of incremental annual copper equivalent production
-
Over the next five years, annual production from Mantoverde is expected to average 135,000 tonnes of copper and 37,000 ounces of gold at attractive C1 cash costs of $1.81 per payable pound of copper produced
- Over the 25-year mine life, production is expected to average 81,000 tonnes of copper and 32,000 ounces of gold at robust C1 cash costs of $2.04 per payable pound of copper produced
- MV Optimized outlines an after-tax net present value at an 8% discount rate (“NPV8%”) of $2.9 billion for the Mantoverde operation on a 100%-basis based on a $4.10/lb long-term copper price assumption
- Capstone plans to begin construction of MV Optimized following acceptance of its environmental DIA permit application and subject to Board approvals. The DIA permit application was submitted in H1 2024 and approval is expected in H1 2025
-
The Company plans to progress several value enhancement initiatives within the Mantoverde-Santo Domingo (“MV-SD”) district, noted in the Opportunities section but not yet incorporated into the base case MV Optimized plan, including:
- Processing of oxide material from Capstone’s neighbouring Santo Domingo and Sierra Norte projects using Mantoverde’s excess SX-EW capacity
- Recovery of cobalt and additional copper from a pyrite concentrate
- Ongoing exploration of the MV-SD district, including the recently acquired Sierra Norte deposit

MV OPTIMIZED EXPANSIONARY CAPITAL COST ESTIMATE
The current process infrastructure of the MVDP can sustain up to 45,000 tpd by debottlenecking minor components of the plant. The expansionary capital costs for MV Optimized have been estimated at $146 million as shown in the following table. This reflects a total capital intensity of approximately $7,500 per tonne of incremental annual copper equivalent production.

| ______________________________ |
3 C1 cash costs are net of gold by-product credits and selling costs. These are Non-GAAP performance measures; please see “Non-GAAP and Other Performance Measures” at the end of this news release. |
Capital for the mine of approximately $38 million reflects the addition of one hydraulic shovel and five haul trucks to support the expanded mining and processing rate of nearly 45,000 tpd, compared to the current nameplate capacity at the Mantoverde Development Project of 32,000 tpd. The strip ratio for MV Optimized has increased to 2.7:1 compared to 2.1:1 for MVDP.
Capital for the processing plant of approximately $84 million reflects additional and/or upgrades to equipment, notably including pipes, pumps, flotation cells, cyclone feed pumps, electrical cabling, and other auxiliary infrastructure to debottleneck the plant.
Capital for the oxide leach optimization of approximately $17 million reflects infrastructure for improved heap and dump management, plus the conversion of the dynamic heap to a bioleach facility to extract sulphide-based copper. The conversion of the dynamic heap to a bioleach facility will also facilitate the potential future extraction of cobalt.
Capital for the desalination plant of approximately $7 million reflects upgrades to ensure a stable flow of the required water for MV Optimized.
For a breakdown of annual capital expenditures, including sustaining and deferred stripping capital, please see Exhibit 1 at the end of this news release.
MINERAL RESERVE ESTIMATE
The Mineral Reserves detailed below consider both oxide and sulphide mineralization as part of the Mantoverde Optimized study. Mantoverde is an open pit-mining complex where oxide ore is treated through both Heap and Dump (ROM) leaching processes and recovered via conventional SX-EW plant to produce copper cathodes. The sulphide ore is processed using a concentrator plant.
The Mineral Reserve was developed by Capstone and contains all Proven and Probable category material planned for processing in MV-O. The designed pit was based on a Lerchs-Grossman optimization process using Whittle software and a detailed phased pit design using the oxide and sulphide pit shells. As a result of the optimization process, six mine phases for oxide material and 15 mine phases for sulphide material were designed to prioritize the higher-grade zones within the mineral extraction plan, while maintaining suitable working widths that would enable high productivity mining sequences using large-scale mining equipment. Mining assumes conventional open pit operations using truck-and-shovel technology.
Following is the current Mineral Reserve Estimate as at June 1, 2024.

MINERAL RESOURCE ESTIMATE
Mantoverde estimated the Mineral Resource using drill data available as of October 17, 2022. The database included 5,109 drill holes, totaling 937,629 meters of drilling, with data composited into 10-meter intervals. The estimation was based on a three-dimensional geological model that incorporated interpretations of lithology, mineralization, and spatial relationships relative to the Mantoverde Fault. The orebody was modeled using a probabilistic approach based on indicator models.
Grades of TCu, SCu, Au, cobalt (Co) and calcium carbonate (CaCO₃) were estimated within a three-dimensional block model using Ordinary Kriging interpolation, applied in three progressively larger passes. Variograms were constructed for each of the sixteen estimation units, supporting the identification of ellipsoid anisotropy and linear trends in the data. High-grade outliers were managed through high-yield restriction (HYR).
Mineral Resources were classified using a geometrical variation of the indicator method (metal and tonnage), which models expected errors and provides a confidence level for production volume estimates. This approach helps quantify the estimation errors in production volumes with a defined level of confidence.
The Mineral Resource Estimates are reported inclusive of those Mineral Resources that have been converted to Mineral Reserves, and use the definitions set out in the 2014 Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Definition Standards for Mineral Resources and Mineral Reserves (the 2014 CIM Definition Standards). Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

COMMODITY PRICING
The MV-O FS assumes analyst consensus commodity price assumptions for copper and gold.
Copper
Capstone markets copper concentrate from its four mining operations. Mantoverde copper concentrate is generally considered clean and low in impurities (deleterious or penalty elements). Capstone foresees substantial demand from trading companies that specialize in blending complex materials with cleaner concentrates. These companies typically prefer concentrates like Mantoverde’s due to their compatibility with blending processes and enhanced value proposition. High-quality concentrates are coveted by both smelters and traders alike. This further supports the expected strong demand for Mantoverde’s copper concentrate in the market.
The analyst consensus long-term copper price was determined to be $4.10/lb which is below the current spot price and compares with the five-year trailing average of approximately $3.73/lb. Analyst consensus copper prices in 2025-2027 of $4.30/lb, $4.40/lb, and $4.40/lb, respectively, were used in the economic model.
Gold
The analyst consensus long-term gold price was determined to be $1,800/oz which is below the current spot price and compares with the five-year trailing average of approximately $1,881/oz. Analyst consensus gold prices in 2025-2027 of $2,200/oz, $2,100/oz, and $2,000/oz, respectively, were also used in the economic model.
FURTHER UPSIDE OPPORTUNITIES
The company plans to continue to progress several value enhancement initiatives within the Mantoverde-Santo Domingo district that are not yet incorporated into the base case MV Optimized plan, or the recently announced Santo Domingo 2024 Feasibility Study.
Copper Oxides
Capstone plans to progress drilling and studies regarding the processing of oxide material from Capstone’s neighbouring Santo Domingo and Sierra Norte projects using Mantoverde’s excess SX-EW capacity. To date, oxide materials have been recognized in the shallower portions of the Santo Domingo, Iris Norte, and Estrellita sulphide orebodies. Currently, these oxides are considered as waste material in the recently announced Santo Domingo 2024 Feasibility Study. Meanwhile, only approximately two thirds of processing capacity is being used at Mantoverde’s SX-EW cathode copper plant. Exploration efforts at Santo Domingo will target a potential 80-100 million tonnes of oxide material, which could add up to 10 thousand tonnes per annum of copper production.
Cobalt
A district cobalt plant for the MV-SD district is designed to unlock cobalt production while reducing sulphuric acid consumption and increasing heap leach copper production. The cobalt recovery process comprises a pyrite flotation step to recover cobaltiferous pyrite from the tailings streams at Mantoverde and Santo Domingo and redirect it to the dynamic heap leach pads, which will be upgraded to a bioleach configuration through the addition of an aeration system as part of MV Optimized. 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 at Mantoverde.
As currently envisioned, a smaller capacity countercurrent ion-exchange plant will initially treat cobalt by-product streams from Mantoverde producing up to 1,500 tonnes per annum of cobalt, and following sanctioning of the Santo Domingo project, the facility will be expanded to accommodate by-product streams from Santo Domingo. In line with this, Santo Domingo has initiated a Feasibility Study to assess the optimum process configuration for the pyrite flotation and pumping transportation facilities needed to transport pyrite concentrate to Mantoverde's leach facilities.
Exploration in the Mantoverde-Santo Domingo District
Capstone has significant untapped exploration potential within MV-SD district. The Mantoverde Optimized plan presented today was prepared without any expansionary drilling campaign since 2019. At Mantoverde, there are 0.2 billion tonnes of Measured & Indicated and 0.6 billion tonnes of Inferred sulphide resources not in reserves. At Santo Domingo, there are 0.1 billion tonnes of Measured & Indicated and 0.2 billion tonnes of Inferred sulphide resources not in reserves. The recently acquired Sierra Norte property also represents an opportunity to potentially be a future feed source in the district. Capstone intends to progress its exploration strategy to service its two eventual processing centers between Mantoverde and Santo Domingo, in addition to continuing to evaluate the potential for Mantoverde Phase II which could include the addition of an entire second processing line at Mantoverde.

Such factors include, among others, changes in project parameters as plans continue to be refined; future prices of commodities; possible variations in mineral resources and reserves, grade or recovery rates; accidents; dependence on key personnel; labour pool constraints; labour disputes; availability of infrastructure required for the development of mining projects; delays in obtaining governmental approvals, financing or in the completion of development or construction activities; objections by the communities or environmental lobby of the Santo Domingo mine and associated infrastructure and other risks of the mining industry as well as those factors detailed from time to time in the Company's interim and annual financial statements and management's discussion and analysis of those statements, all of which are filed and available for review on SEDAR+ at www.sedarplus.ca. Although the Company has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward looking statements.
Non-GAAP and Other Performance Measures
The Company uses certain performance measures in its analysis. "C1 Cash Costs" and "Total Project Operating Cost" are Non-GAAP performance measures. 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.
