Advancement Of Yuty Prometeo Uranium Project

VANCOUVER – Vanguard Mining Corp. is preparing an initial NI 43-101 Technical Report on its newly acquired Yuty Prometeo Project in southeastern Paraguay, with completion expected within the next 30 days. days. This update follows the previously announced Letter of Intent (LOI) on April 8, 2025, regarding Vanguard’s acquisition of a 90,000-hectare (222,395-acre) land package comprising the San Jose and Prometeo concessions. The Yuty Prometeo is situated within the Paraná Basin, adjacent and contiguous to UEC’s Yuty Project, which hosts a defined uranium resource of 8.96 million pounds.

David Greenway, CEO, said, “I view the acquisition of the Yuty Prometeo as a transformative milestone in our uranium exploration strategy. These highly prospective concessions—located adjacent to UEC’s established multi-million-pound Yuty deposit—strategically position us in one of the most promising uranium regions in South America. Bringing Ariel on board to prepare the initial NI 43-101 Technical Report is a valuable addition to this initiative, and I look forward to his insights and guidance as we advance the project."

The Yuty Prometeo consists of four (4) concessions—three (3) San Jose concessions and one (1) Prometeo concession—covering a combined area of approximately 90,000 hectares (222,395 acres) within the uranium-rich Paraná Basin in southeastern Paraguay. The Prometeo Concession spans approximately 27,666 hectares (68,368 acres) and is directly contiguous to UEC’s Yuty Project. Historical records reference 28 drill holes on the property, with uranium values ranging from 0.05% to 0.10% U3O8. Data from previous work by the Anschutz Corporation suggest that the Prometeo block lies on trend with UEC’s adjacent Transandes block.

The San Jose Concessions total approximately 62,210 hectares (153,754 acres) across three adjacent concessions, located along the Upper Permian–Carboniferous contact—about 100 km northwest of UEC’s Yuty Project and 40 km west of its Coronel Oviedo Project. A radiometric car survey conducted over a 40 km by 10 km area identified significant uranium anomalies across the property.
