Jaguar Uranium Initiates Rare Earth Element Assessment at Colombia’s Berlin Mining Project

Berlin has historically reported indications of Rare Earth Elements, Vanadium, Phosphate and Uranium — Positioned as Potential Non-Chinese Critical Minerals Project in the Western Hemisphere

TORONTO — Jaguar Uranium Corp. (NYSE American: JAGU) has commenced an initial rare earth element assessment program at its flagship Berlin Project in Caldas, Colombia. The site is a polymetallic sedimentary deposit containing uranium mineralization alongside associated rare earth elements (REE) and battery-related commodities such as vanadium, phosphate, nickel, molybdenum, rhenium, and yttrium.

The company plans to utilize approximately 20,000 meters of preserved historic drill core for selective re-sampling and assaying. This approach is intended to advance early-stage REE characterization without the immediate requirement for new drilling. The program represents the first dedicated effort by the company to evaluate the rare earth potential of the 9,053-hectare concession area.

“The results could be a step-change in how this project is understood and technically evaluated.” — Steven Gold, Chief Executive Officer, Jaguar Uranium Corp.

“We are now attempting to advance the recognition that Berlin could represent a relevant non-China based critical mineral deposits in the western hemisphere and specifically in Latin America,” stated Steven Gold, Chief Executive Officer of Jaguar Uranium Corp. “We believe the results could be a step-change in how this project is understood and technically evaluated.”

The strategic shift toward REE evaluation follows a period of increased global policy attention regarding critical mineral supply chains. Materials required for defense systems, electric vehicles, and clean energy infrastructure have become a priority for Western governments seeking to diversify away from Chinese-dominated markets. Gracelin Baskaran, director of the Critical Minerals Security Program at the Center for Strategic and International Studies (CSIS), has indicated that the US and the European Union are working to foster independent markets for these materials.

The Berlin Project deposit is situated within a layered sedimentary sequence of phosphate-bearing limestone. The company is employing a three-phase approach for its assessment: core logging and systematic re-sampling, multi-element geological modeling, and an evaluation of by-product economics. This modeling will integrate REE assay data with existing datasets for uranium, vanadium, and phosphate to establish a technical foundation for future resource estimates.

Infrastructure at the site includes proximity to a hydroelectric power source 12 kilometers away and access to a river port approximately 65 kilometers from the project, providing a logistical route to the Caribbean coast. The company, which completed a $25 million USD initial public offering on the NYSE American (NYSE American: JAGU) in February 2026, is also managing the Laguna Salada Project in the Argentine province of Chubut and the Huemul mine in Mendoza.

Technical information regarding the program was approved by Owen D. W. Miller, a qualified person as defined by NI 43-101. The company noted that the Berlin Project remains in the exploration stage and does not currently host mineral resources or reserves as defined under SEC Regulation S-K 1300.
