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.

On December 3, 2025, Collective Mining Ltd. (NYSE: CNL, TSX: CNL) announced assay results from three orthogonal diamond drill holes designed to continue expanding the high-grade Ramp Zone (“Ramp”), a component of the company’s flagship Apollo system within the Guayabales Project in Caldas, Colombia.

The results confirm broad and continuous intervals of reduced intrusion-related gold mineralization, extending the Ramp Zone to 300 meters of strike by 270 meters vertical. The company stated that the zone remains open in all directions.

The Ramp Zone, situated at approximately 1,000 meters above sea level at the bottom of the Apollo system, is part of a large, partially Reduced Intrusion Related System (RIRS) mineralized with gold, silver, copper, and tungsten. Drilling at Apollo has outlined continuous mineralization from the surface to more than 1,370 vertical meters.

Drill Hole Results Detail

The deepest and northeastern-most hole reported to date, APC143-D1, intercepted 23.35 meters grading 8.24 g/t gold and 8 g/t silver. This intercept was contained within a broader interval of 76.10 meters grading 3.26 g/t gold and 4 g/t silver, starting from 409.60 meters downhole. This result expanded the Ramp Zone’s dimensions from the previously stated 275 meters of strike by 200 meters vertical.

A second hole, APC140-D2, locally extended the Ramp Zone by 50 meters to the northwest. This hole cut 16.40 meters grading 8.44 g/t gold and 19 g/t silver within a 55.10-meter interval grading 3.06 g/t gold and 7 g/t silver, beginning at 243.10 meters downhole.

A related wedge hole, APC140-D1, intersected two mineralized segments: 47.70 meters grading 1.98 g/t gold and 5 g/t silver from 527.40 meters downhole, including 15.15 meters grading 3.00 g/t gold and 8 g/t silver; and 14.15 meters grading 2.13 g/t gold and 4 g/t silver from 598.55 meters downhole.

Operational and Financial Status

The company has contracted a third deep-capacity diamond rig to operate at the Ramp Zone, with two additional deep-capacity rigs scheduled to arrive in mid-Q1 2026. Two additional drill holes into the Ramp Zone (APC143-D2 and APC143-D3) are pending assay results; these holes were reported to have intersected 18 sightings of visible gold, compared to none observed in the results detailed in this announcement.

To date, Collective Mining has completed 150,000 meters of diamond drilling across the Guayabales and San Antonio projects, with 105,000 meters dedicated to the Apollo system. Ten rigs are currently operating on site.

The company stated that it is fully funded for its aggressive 2026 program, which targets up to 100,000 meters of additional drilling, based on a cash position of $135 million USD as of December 1, 2025.

Executive Chairman Ari Sussman commented on the results, noting that hole APC143-D1 extended the zone along strike and at depth and demonstrated consistent mineralization over substantial widths.

The continued presence of Ramp Zone mineralization at least 270 meters beneath the initial discovery at 1,000 meters above sea level supports the view that the drilling may have only tested the top of a large intrusion-related gold system that shares mineralogical similarities with the multi-million ounce Marmato Deeps Zone.
