VANCOUVER, BC, June 17, 2025 /CNW/ - (TSX: LUN; Nasdaq Stockholm: LUMI) Lundin Mining Corporation ("Lundin Mining" or the "Company") will host a Capital Markets Day on June 18, 2025 to outline the Company's strategic aspirations to become a global top-ten copper producer and achieve copper production of over 500,000 tonnes per year and gold production of over 550,000 ounces ("oz") per year. The Company will present on multiple initiatives identified to date that are expected to support its strategic vision, including growth initiatives at its operations, as well as the development of the Vicuña district, which is recognized as one of the world's largest copper, gold and silver Mineral Resources (see Lundin Mining's News Release dated May 4, 2025). Unless otherwise stated, dollar amounts are presented in United States dollars on a 100% basis.

Jack Lundin, President and CEO commented, "Lundin Mining is entering an exciting new growth phase, underpinned by a clear path to increase copper production through low-cost brownfield expansions at Candelaria, Caserones, and Chapada. These projects are expected to deliver meaningful production gains over the next three to five years. Across all our operations, we see significant exploration upside, including promising opportunities at Eagle that could meaningfully extend the life of mine. In parallel, our Vicuña Project offers transformational long-term growth potential. Backed by a significantly strengthened balance sheet, reduced cash costs, robust free cash flow generation, and a best-in-class team, we are well-positioned to continue returning capital to shareholders while advancing our ambition of becoming a top-ten global copper producer."

Growth Initiatives

The Company has outlined medium-term brownfield expansion opportunities over the next three to five years to grow copper production by 30,000 - 40,000 tonnes per year through low capital intensity projects, including those at Candelaria, Caserones and Chapada described below.

• Candelaria: Management has reworked the previously envisioned Candelaria Underground Expansion Project (CUGEP) to a lower capital-intensive option with only marginally lower production rates. The expansion opportunity includes the insourcing of Lundin Mining's underground mining contract, which is anticipated to provide incremental copper production gains from higher productivity rates through better mechanical availability and higher development rates. Through initiatives identified, underground throughput capacity could increase by 50% to 60% (to ~22,000 tonnes per day) from current levels (12,000 to 14,000 tonnes per day). The Company forecasts that this could increase annual copper production at Candelaria by approximately 10% or 14,000 tonnes of copper per year at a low cost of capital.
• Caserones: While leaching improvements have incrementally increased cathode production over recent quarters, the cathode plant remains underutilized. The Company forecasts that through continued improvements with its leaching practices and additional oxide material, incremental future production can be realized in the range of 7,000 - 10,000 tonnes of copper per year.
• Chapada: Internal scoping studies for the Saúva project have identified the potential to add approximately 15,000 to 20,000 tonnes of copper production per year and 50,000 to 60,000 ounces of gold production per year, representing 50% and 100% production increases at Chapada for copper and gold respectively. This brownfield project is ~15 km from the Chapada mine and is undergoing a prefeasibility study, which is expected to be completed by the end of the year.
• Eagle: Exploration is underway at the Boulderdash project where Lundin Mining has entered into exclusivity for a 70% earn-in agreement with Talon Metals Corp. (see Lundin Mining's News Release dated March 5, 2025). The Boulderdash exploration properties are adjacent to the Company's Eagle mine. Exploration success at Boulderdash could meaningfully extend the life of mine at Eagle.

In addition to the growth initiatives at its operations, Lundin Mining holds a 50% interest in the Vicuña Project (comprised of the Filo del Sol and Josemaria deposits), which has the potential to transform the Company's copper, gold and silver production profile.

• Vicuña Project: The recently published Mineral Resource estimate for the Vicuña Project highlights one of the world's largest copper, gold and silver Mineral Resources, with the potential to support a globally ranked mining complex. The Company continues to advance the integrated study of Filo del Sol and Josemaria, which is expected to be completed in Q1 2026. The integrated study will outline a development concept for the combined project, including a production profile and capital estimate.

Financial Outlook

The Company continues to return capital to investors targeting an annual distribution of $220 million through a combination of regular dividends and share buybacks. The Company's 2025 production guidance remains unchanged and, based on the mid-point of the production guidance and on the Company's forecast copper price of $4.40/lb copper, revenue for 2025 is forecast to be approximately $3.7 billion with adjusted operating cash flow¹ of $1.3 billion and adjusted free cash flow from operations² of $800 million. The Company is also providing guidance on its financial performance over the next five years, from 2025 to 2029 with forecast cumulative earnings before interest, taxes, depreciation and amortization (EBITDA)1 of $8.1 billion, adjusted operating cash flow1 of $6.5 billion and adjusted free cash flow from operations2 of $4.9 billion.³

Lundin Mining will host a Capital Markets Day on Wednesday, June 18, 2025, from 8:00 am to 12:00 pm ET. The event can be viewed as follows:

2025 Guidance Updates

In addition, the Company is providing an update on its cash cost and capital expenditures guidance.  

The Company remains on track to meet annual consolidated production guidance for copper, gold and nickel. Total consolidated copper production for the two months April and May 2025 was 53,000 tonnes and year to date to the end of May 2025 is 129,800 tonnes.

Cash cost guidance at Chapada has been reduced as cash costs continue to benefit from increased realized prices on by-product gold sales and weaker local currency while the cash cost guidance for the other assets remains unchanged.  As a result, the consolidated cash cost⁴ guidance is being reduced from $2.05 - $2.30/lb to $1.95 - $2.15/lb copper.

Annual sustaining capital expenditure⁵ guidance has remained at $530 million with reductions at Caserones due to rescheduled projects, being offset by higher capital expenditure on tailings at Chapada. Expenditure guidance related to expansionary capital5 has increased from $205 million to $265 million, primarily driven by an increase in the Vicuña Project budget.

Historical Non-GAAP Measure Comparatives

Cash cost, adjusted operating cash flow, free cash flow from operations, adjusted free cash flow from operations, EBITDA and expansionary capital expenditures are non-GAAP financial measures and sustaining capital expenditures is a supplementary financial measure. These performance measures have no standardized meaning within generally accepted accounting principles under IFRS and, therefore, amounts presented may not be comparable to similar data presented by other mining companies. These amounts are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. Please refer to the section titled "Non-GAAP and Other Performance Measures" in Lundin Mining's Management's Discussion and Analysis for the year ended December 31, 2024 and for the three months ended March 31, 2025, which are incorporated by reference herein and which are available on SEDAR+ at www.sedarplus.ca.

Adjusted free cash flow from operations is a non-GAAP financial measure defined as cash flow provided by operating activities, excluding general exploration and business development costs and deducting sustaining capital expenditures (as separately defined) and non-cash working capital items. Adjusted free cash flow from operations is indicative of the Company's ability to generate cash from its operations after consideration of required sustaining capital expenditure necessary to maintain existing production levels, and removing the impact of working capital, which can experience volatility from period-to-period.
