Alamos Gold Announces Island Gold District Base Case Life of Mine Plan Outlining One of the Largest and Lowest-Cost Gold Mines in Canada with Significant Upside

Core Viewpoint - Alamos Gold Inc. has reported the results of the Base Case Life of Mine Plan for the Island Gold District, indicating it is expected to become one of Canada's largest, lowest-cost, and most profitable gold mines, with significant upside potential anticipated in an upcoming Expansion Study [1][3][4]. Summary by Relevant Sections Base Case Life of Mine Plan - The Base Case LOM Plan integrates Island Gold and Magino into a consolidated operation, reflecting current costs and significant growth in Mineral Reserves [2][4]. - The plan includes only Mineral Reserves from Island Gold and Magino, with additional resources not factored into the economic analysis [2][12]. Production and Cost Metrics - Average annual gold production is projected at 411,000 ounces starting in 2026, a 43% increase from 2025 guidance [4][8]. - Mine-site all-in sustaining costs (AISC) are expected to average $915 per ounce over the initial 12 years, a 19% decrease from 2025 guidance [4][51]. - Total cash costs are projected to average $581 per ounce over the initial 12 years and $699 per ounce over the life of mine [7][51]. Mineral Reserves and Resources - Total Mineral Reserves have increased by 48% to 6.3 million ounces, with significant contributions from both Island Gold and Magino [7][12]. - The conversion of Inferred Mineral Resources to Mineral Reserves is ongoing, with a high conversion rate expected to continue [16][12]. Expansion and Future Growth - An Expansion Study is anticipated in Q4 2025, which is expected to outline further increases in Mineral Reserves and potential milling rates of 18,000 to 20,000 tonnes per day [3][4][8]. - The Phase 3+ Expansion is expected to be completed in the second half of 2026, which will enhance production capabilities and lower costs [5][27]. Environmental Considerations - The project aims for a 29% reduction in greenhouse gas emissions per ounce produced, achieving an intensity 70% lower than the industry average [5][40]. Financial Metrics - The after-tax net present value (NPV) of the Base Case LOM Plan is estimated at $4.5 billion at a long-term gold price of $2,400 per ounce, increasing to $6.7 billion at current prices of approximately $3,300 per ounce [21][22]. - Total capital expenditure for the life of mine is projected at $2.26 billion, or $380 per ounce sold [66]. Capital Expenditures - Growth capital is estimated at $453 million, primarily focused on the Phase 3+ Expansion and Magino mill expansion [60][64]. - Sustaining capital is expected to total $1.8 billion over the life of mine, with a per-ounce cost of $304 [66]. Operational Details - The Magino mill will process ore from both Island Gold and Magino, with a planned throughput of 12,400 tonnes per day post-expansion [48][49]. - The transition to a shaft operation is expected to significantly reduce costs and improve efficiency [26][31].
