Mineros Announces Updated Prefeasibility Study for the Porvenir Project and Highlights Emerging Porvenir Polymetallic District
Mineros Transforms into High-Yield Growth Engine with Robust Porvenir PFS and Strategic Colombian Acquisition

The most recent news (March 31, 2026) details an updated Prefeasibility Study (PFS) for the 100%-owned Porvenir Project in Nicaragua. The study outlines a post-tax NPV5% of $460M, an IRR of 37.9%, and a rapid 2-year payback. Initial capital is estimated at $206.8M to produce an average of 72.3 koz AuEq annually over a 9-year mine life. This follows a string of material announcements in Q1 2026, including the acquisition of a massive gold exploration project in Tolima, Colombia, from AngloGold Ashanti (historical resource of ~28 Moz Au) for $10M upfront, and the reporting of record FY2025 financial results ($800M revenue, $145M net profit).
The Porvenir PFS is a material positive milestone that confirms the project's robust economics at current metal prices, significantly exceeding the 2023 internal estimates mentioned in transcripts. - Economic Viability: The 37.9% IRR and $460M NPV provide a clear path to organic production growth, diversifying the company's reliance on artisanal "Bonanza" partners. - Strategic Pivot: The acquisition of the Tolima project (formerly La Colosa) for a relatively small upfront cash payment ($10M) gives Mineros control over one of the largest undeveloped gold resources in South America, though it carries significant social and environmental permitting risks. - Financial Strength: Record 2025 EBITDA of $358M and a cash position of $108M (post-tax settlement and acquisitions) demonstrate that the company can self-fund a significant portion of its $113.7M 2026 CapEx budget. - Shareholder Returns: The approval of an $80M share repurchase program and a $0.10/share dividend confirms management's commitment to returning capital even during a growth phase.
Mineros S.A. is a Latin American gold producer with operations in Colombia (Nechí Alluvial) and Nicaragua (Hemco). - Flagship Project: The Porvenir Project (Nicaragua) is now the primary growth driver, designed as a 2,000 tpd underground mine. - Secondary Growth: La Pepa (Chile) and the newly acquired Tolima Project (Colombia) provide long-term optionality. - Operational Model: Unique "Bonanza" model in Nicaragua where the company processes ore from artisanal mining partners, providing high-margin cash flow but increasing AISC sensitivity to gold prices.
