Celsius Resources Limited Announces the Results of the Definitive Feasibility Study for the Maalinao-Caigutan-Biyog Copper-Gold Project
Celsius Resources Limited announced the results of the Definitive Feasibility Study ("DFS") for the Maalinao-Caigutan-Biyog Copper-Gold Project ("Project") which is held under its Philippine affiliate Company, Makilala Mining Company Inc. ("MMCI"). The MCB Project is owned and operated by MMCI and Celsius has 40% working interest in M CB as Celsius conditionally agreed to transfer a 60% working interest in the MCB Project to Sodor Inc, subject to certain conditions, which remain outstanding, as announced on 20 March 2023. The Study demonstrates a technically robust and economically enhanced project, with competitive capital intensity and operating costs. The outcomes are derived from engineering and cost estimates developed predominantly on a first-prin principles basis, supported by defined mine plans, process plant design, infrastructure layouts, execution methodology and contractor benchmark inputs. Initial access and early production are established via a decline with truck haulage during the first three years, followed by commissioning of a vertical shaft and hoisting system that becomes the primary material handling system as the mine deepens to improve haulage efficiency, reduce operating costs, and support higher production rates over the long term. Operating cost estimates for the MCB Project were prepared by Ausenco on behalf of MMCI, incorporating mining costs developed by DMT with owner's general and administration costs (G&A), power and fuel pricing provided by MMCI. Mining, reagents, paste backfill binder, and dry-stack tailings operating and sustaining capital costs have all been derived on a first-principles basis, using defined mine plans, testwork-based consumption rates, quoted material prices, contractor rates and fuel consumption. The current mine plan aligns with the process plant ramp-up, achieving steady-state production of 2.28 Mt/y during the initial operating period of three years, before increasing to 2.64 Mt/y for the majority of the mine life as underground infrastructure is established. As higher-grade stopes are depleting and feed grades declining, the Project presents a clear opportunity to increase ore throughput to sustain concentrate production and enhance project value. Preliminary assessments indicate that, subject to further study, the existing process plant primarily could support an increase to up to 3.0 Mt/y, leveraging established mine infrastructure and potential concentrator upgrades, while mineralisation remains open at depth, providing additional long-term optionality. Structured risk assessments and specialist reviews were used to inform mine design, site layout, execution strategy and early works planning, resulting in engineering solutions that reduce risk exposure, improve constructability and schedule confidence, and enhance project value.
