What Samuel Delivered for Los Azules

• Feasibility, leadership, and coordination of multiple international contributors. Study planning and management of work streams across the full span of technical areas and specialist contributors to the feasibility study.
• Feasibility‑level process and plant engineering. Completed multiple options analysis for process paths to. Developed the selected heap‑leach + SX/EW process flow design basis, mass and energy balances, and process equipment lists aligned with the study’s objective to produce high‑purity copper cathodes on site.
• Metallurgical test work development, coordination, and modeling. Managed metallurgical program inputs and technical interpretation to validate leach kinetics, recoveries, and reagent consumptions feeding the FS process models used to size circuits and estimate operating costs.
• CapEx / OpEx estimating and constructability reviews. Produced class‑level capital and operating cost estimates and delivered constructability and sequencing input to reduce schedule risk and refine the project’s initial capital envelope.
• Infrastructure and site integration: Engineered site layout options, access and utilities strategies, and integration with proposed renewable power and water‑use reduction measures that underpin the project’s low environmental footprint and operational eff iciency.
• Permitting and ESG integration support. Worked alongside environmental and social specialists to embed mitigation measures, community engagement inputs, and resource‑efficient process choices into the FS deliverables that contributed to the project’s ESG positioning.
• Construction planning and early procurement advice. Provided execution‑strategy recommendations, long‑lead procurement priorities, and contractor interface scopes to accelerate the path from feasibility to construction readiness.

Why Samuel Engineering was the Right Partner

• Mining and hydrometallurgical experience Our team combines hands‑on mining process engineers, metallurgists, and EPCM construction planners who convert large‑scale resource studies into realistic, bankable engineering solutions.
• End‑to‑end Feasibility study capability We cover the spectrum from testwork supervision and process selection through to capital forecasting, risk‑based constructability reviews, and staged execution planning.
• Built‑for‑low‑impact projects Samuel Engineering specializes in designs that reduce water use, minimize land disturbance, and simplify tailings management; these approaches align with Los Azules’ low‑impact heap leach + SX/EW concept and renewable‑power focus
• ESG‑aware engineering Our engineering integrates environmental and social considerations early in design, so projects meet permitting expectations and attract sustainable financing partners.
• Practical constructability and procurement focus. We design with buildability and supply‑chain realities in mind, recommending long‑lead equipment strategies and contractor interfaces that de‑risk schedule and cost.

Project Highlights We Contributed Toward

• Leadership of a Feasibility Study that meets our client’s needs and confirms Los Azules as a long‑life, low‑cost producer of high‑purity copper cathodes and advances the project toward construction readiness
• Technical and commercial insight and inputs that align with a project and process route designed to reduce environmental footprint and enable on‑site production of LME Grade A cathodes
• Engineering and execution advice that helped position the project to attract strategic financing and partnerships focused on ESG‑aligned mining development
