On March 8, 2026, Mineros S.A. declared that it had reached a final deal with a subsidiary of AngloGold Ashanti to purchase a 100% stake in a major gold exploration project situated in the Department of Tolima, Colombia. The following is an overview of the transaction’s main details:
Details on the Topic
Mineros S.A., the acquirer (TSX: MSA, OTCQX: MNSAF, BVC: MINEROS)
Seller: AngloGold Ashanti PLC (purchased through AngloGold Ashanti Colombia S.A.S. shares)
Project Location: Cajamarca Municipality, Tolima Department, Colombia. About 30 kilometers west of Ibagué and 150 km west of Bogotá.
Project Specifics Previously called La Colosa. A gold asset in the exploratory stage that is owned by the integrated mining concession contract (code EIG-163). Since 2017, most exploration has been halted.
Acquisition Cost: $10 million in cash at closing, plus up to $60 million in contingent payment based on future environmental licensing and ore tonnage permits.
Closing in the first quarter of 2026 is anticipated.
📊 Historical Background and Project Resources
Although Mineros has not yet confirmed this information, the project is regarded as a big exploration asset with a considerable historical gold resource.
Historical Mineral Resource Estimate (as announced by AngloGold Ashanti in December 2024) :
23.35 million ounces of gold with an average grade of 0.87 g/t are the indicated resources.
4.98 million ounces of gold with an average grade of 0.71 g/t are the inferred resources.
Important Information: No declared mineral reserves exist. This is not being treated as a current resource by Mineros, and in order to reclassify it, more verification work, including more drilling, would be required.
Regulatory Context: Environmental authorization and regulatory clarity are prerequisites for the project’s progress. Parts of the historical resource estimate may be impacted by the ongoing legal actions surrounding the delineation of the Los Nevados Páramo.
🤝 Community Approach and Strategic Justification
With more than 50 years of experience operating in Colombia, Mineros views this acquisition as a strategic fit that makes use of its local knowledge. The company’s strategy for the project is focused on responsible development and community involvement.
Local Stewardship: Mineros feels it is well-positioned to further the initiative because of its extensive local expertise and history of positive community involvement.
Rebranding the Project: A crucial component of the plan is to abandon the project’s previous name, “La Colosa.” In order to represent common values and a new beginning, Mineros intends to undertake a cooperative process with local stakeholders to design a new project identity, including a new name.
Conditional Advancement: The business has made it clear that obtaining three essential components—environmental authorization, regulatory clarity, and significant community consensus—will be necessary for any further project advancement.
In addition to its current activities in Colombia and Nicaragua, as well as its La Pepa project in Chile, this acquisition adds significantly to Mineros’s exploration portfolio in Colombia.
