Aldebaran PEA for the Altar Project Reports 48 Year Mine Life, After Tax NPV (8%) of US$2 Billion, and 20.5% IRR

Core Viewpoint - Aldebaran Resources Inc. announced the results of a Preliminary Economic Assessment (PEA) for the Altar copper-gold project in Argentina, indicating strong potential for a long-life, high-quality copper operation with significant production and cash flow generation [1][6][8]. Economic Highlights - The PEA outlines a 48-year mine life with an average annual production of 101,413 tonnes of copper equivalent (CuEq) over the life of the mine (LOM) [7][10]. - The project has an after-tax Net Present Value (NPV) of $2.0 billion at an 8% discount rate, an Internal Rate of Return (IRR) of 20.5%, and a payback period of 4 years based on base-case metal prices [7][11]. - Total LOM gross revenue is projected at $44.7 billion, with free cash flow estimated at $10.7 billion [7][11]. Production and Cost Metrics - Initial capital expenditure (capex) is estimated at $1.59 billion, with a capital intensity of $15,713 per tonne of average annual CuEq produced [7][12]. - Cash costs (C1) are projected at $1.71/lb payable Cu for the first 20 years, increasing to $2.02/lb for the LOM [7][12]. - All-in Sustaining Costs (AISC) are estimated at $2.25/lb payable Cu for the first 20 years, rising to $2.59/lb for the LOM [7][12]. Mining and Processing Overview - The mining method combines open-pit and underground block caving, with a processing capacity of 60,000 tonnes per day [10][21]. - The project anticipates a recovery rate of 87.76% for copper, 57% for gold, and 50% for silver over the LOM [12][26]. Strategic Partnerships and Future Plans - Aldebaran is collaborating with Nuton, a Rio Tinto venture, to explore alternative processing technologies that could enhance economic viability and reduce environmental impact [8][38]. - The company plans to focus on a Pre-Feasibility Study (PFS) and resource updates in the next 12 to 18 months, aiming to unlock additional value from the Altar project [8][46]. Mineral Resource Estimate - The PEA is based on an updated mineral resource estimate, with approximately 80% of the resources categorized as Measured and Indicated [7][14]. Infrastructure and Environmental Considerations - The project includes comprehensive on-site infrastructure and plans for water management, with a focus on minimizing environmental impact [35][36]. Market Context - The political environment in Argentina is shifting towards pro-business policies, which may benefit the advancement of the Altar project amid rising global demand for copper [8].
