Exciting Developments in the Diamba Sud Gold Project
All financial information contained herein is expressed in US dollars unless otherwise stated.
FORTUNA MINING CORP. (NYSE: FSM | TSX: FVI) has unveiled positive results from the Preliminary Economic Assessment (PEA) for the Diamba Sud Gold Project, positioned to potentially empower the company with significant economic advantages.
This assessment projects a compelling after-tax NPV5% of $563 million at a gold price of $2,750 per ounce, alongside an impressive IRR of 72% and a swift payback period of only ten months. Over the initial three years of operations, production is anticipated at an average of 147,000 ounces of gold per year, with an All-In Sustaining Cost (AISC) of $904 per ounce.
Financial Strength Underpinning Project Success
The construction capital cost for the Diamba Sud project has been estimated at around $283.2 million. Fortuna's solid balance sheet and robust cash generation facilitate the attainment of the functional capital necessary for development, boasting liquidity of $537.3 million by the end of Q2 2025, alongside a net cash position of $214.8 million.
Jorge A. Ganoza, President and CEO of Fortuna, emphasized the overwhelming value the Diamba Sud Project contributes to the company. With permitting processes and the Definitive Feasibility Study (DFS) actively progressing, stakeholders remain optimistic about a construction decision potentially arriving in the first half of 2026.
Exploration and Resource Expansion Potential
Fortuna continues to focus on enhancing Diamba Sud’s production profile through exploration activities. A total of five drill rigs are operationally active, aiming to extend mineralization areas and upgrade Inferred Mineral Resources to the Measured and Indicated categories before year-end.
Recent drilling has revealed promising results, such as the DSDD488 drill hole intercepting 22.7 g/t Au, showcasing the project's expansive exploration upside.
Project Operational Details
The PEA illustrates the design of an open-pit gold mining operation that encapsulates several deposits, including Area A, Area D, and Southern Arc, sustaining a central processing facility across an estimated life of mine (LOM) of 8.1 years.
With a targeted throughput of 2.5 million tonnes per year for the first three years—mainly focused on high oxide content—operations are projected to transition to a sustained rate of 2.0 Mtpa from year four when fresh material becomes more predominant.
Mining methods will incorporate conventional open-pit strategies, alongside a carefully crafted processing plan aimed at optimizing gold recovery while controlling costs. The robust mining inventory is derived from detailed optimization shells calculated using a gold price of $2,300 per ounce, effectively accounting for various cost parameters.
Environmental Considerations and Sustainability
Fortuna is proactive in its environmental stewardship. The environmental and social impact assessment (ESIA) has been filed, marking a key step in the permitting progress. A major focus lies on minimizing the ecological effects of operations while engaging with the community through sustainable practices.
Next Steps Towards Feasibility and Construction
With an approved budget of $17 million targeting early construction works, including enhancements to camp facilities and detailed engineering initiatives, Fortuna aims to solidify Diamba Sud’s position as a formidable project in the mining sector. The completion of the DFS is projected for the latter part of Q2 2026, heralding the potential commencement of full construction operations by the fourth quarter of 2026.
Overall, Fortuna’s forward-looking measures and optimized designs provide stakeholders with confidence in the Diamba Sud Project’s economic potential and longevity within the company’s portfolio.
