Alamos Gold Announces Island Gold District Expansion to 20,000 TPD, Creating One of Canada’s Largest and Lowest Cost Gold Mines with Attractive Economics, including 69% After-Tax IRR and $12.2 Billion NPV at $4,500/oz Gold

Core Viewpoint - Alamos Gold Inc. has reported significant advancements in its Island Gold District operation, including a 30% increase in Mineral Reserves and an expansion of the Magino mill to 20,000 tonnes per day, which is expected to enhance production and profitability, positioning it as one of Canada's largest and most profitable gold operations [1][2]. Production and Economic Highlights - The IGD Expansion is projected to increase average annual production to 534,000 ounces over the next 10 years, a 27% increase from the Base Case Life of Mine Plan [3][4]. - The total gold production is expected to rise from 5,836,000 ounces in the Base Case to 7,963,000 ounces under the Expansion Study [4]. - Average mine-site all-in sustaining costs (AISC) are anticipated to decrease by approximately 31% to $1,025 per ounce over the initial 10 years post-expansion [3][47]. Mineral Reserves and Resources - The IGD Expansion Study has increased the Proven and Probable Mineral Reserves to 8.3 million ounces, a 30% increase from the previous estimate of 6.3 million ounces [7][19]. - Underground Mineral Reserves have risen by 25% to 5.1 million ounces, while open pit Mineral Reserves increased by 40% to 3.1 million ounces [8][9]. Capital Expenditure - Growth capital for the IGD Expansion is estimated at $542 million, focusing on the Magino mill expansion and accelerated underground development, with total growth capital expected to reach $704 million [55][56]. - The capital for the mill expansion to 20,000 tpd is estimated at $200 million, with significant spending anticipated in 2026 and 2027 [57][58]. Environmental Impact - The IGD Expansion is expected to achieve a 56% reduction in greenhouse gas emissions per ounce produced, further decreasing the emission intensity to 70% lower than the industry average [36][47]. Operational Improvements - The expansion will include enhancements to the Magino mill circuit, such as a new truck dump configuration and a centralized gyratory crusher, aimed at improving processing efficiency and reducing costs [22][40]. - The transition to shaft operations is expected to stabilize costs and improve mining efficiency, with underground mining rates projected to increase to 3,000 tpd by 2029 [23][29]. Financial Projections - The after-tax net present value (NPV) of the IGD Expansion is estimated at $8.2 billion at a long-term gold price of $3,200 per ounce, increasing to $12.2 billion at a price of $4,500 per ounce [13][14]. - The after-tax internal rate of return (IRR) is projected at 53% based on the $3,200 gold price and 69% at $4,500 [14][18]. Summary of Costs - Total cash costs are expected to average $682 per ounce over the initial 10 years post-expansion, reflecting a significant decrease from previous estimates [47][51]. - Open pit mining costs are projected to average C$4.85 per tonne, while underground mining costs are expected to average C$135 per tonne [48][51].
