Vanguard Advances Prospection Permit Process with MADES at Yuty Prometeo Uranium Project, Neighboring UEC's Yuty Project

The submission of this Environmental License Application marks a significant milestone for Vanguard, as it advances the Company's progress toward obtaining a Prospection Permit from MADES, a key step in positioning Vanguard to secure full exploration and development approvals for the strategically located Yuty Prometeo Uranium Project in southeastern Paraguay, an emerging energy jurisdiction with growing importance in the global nuclear fuel supply chain.

David Greenway, CEO of Vanguard Mining Corp., "By advancing the permitting process at Yuty Prometeo, we are de-risking the project's timeline, strengthening our uranium asset pipeline, and enhancing long-term value creation opportunities for shareholders in a market increasingly driven by global energy security and nuclear power demand. We are excited to begin exploration and development at the Yuty Prometeo concessions, underscoring our commitment to building a dominant uranium portfolio in South America. Paraguay offers a unique combination of political stability, investor-friendly policies, and untapped mineral potential, making it an ideal jurisdiction for long-term uranium exploration. With modern exploration techniques across this historically prospective district, we see clear opportunity to unlock value as part of our global objective to secure critical minerals that will fuel the clean energy transition."

About the Yuty Prometeo Project

The four concessions - including the three San Jose and one Yuty Uno concession - collectively span approximately 90,000 hectares (222,395 acres) within the prolific Paraná Basin, one of South America's most promising uranium regions. The project area is located adjacent to Uranium Energy Corp.'s ("UEC") established Yuty Deposit, which hosts an Indicated resource of 8.96 million pounds of U?O?.1

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% U?O?. 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 encompass approximately 62,210 hectares (153,754 acres) across three contiguous claims situated along the Upper Permian-Carboniferous contact, approximately 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 delineated significant uranium anomalies across the property. Collectively, these concessions represent a strategically positioned and highly prospective uranium exploration asset within one of South America's most promising uranium districts.

About UEC's Yuty ISR Project

UEC's adjacent Yuty ISR Project in southeastern Paraguay spans approximately 117,359 hectares (290,000 acres) and hosts an Indicated resource of 8.962 million lbs U?O? (9,074,000 tons grading 0.049% U?O?), and an Inferred resource of 2.203 million lbs U?O? (2,733,000 tons grading 0.040% U?O?), as disclosed in its July 1, 2022, technical report titled "Yuty Uranium Project Initial Assessment US SEC Subpart 1300 Regulation SK Report, Paraguay SA.2 " The project is considered amenable to in-situ recovery (ISR), the same extraction method UEC employs at its Texas operations.

UEC secured a 100% undivided interest in the Yuty Project through its March 30, 2012, acquisition of Cue Resources Ltd. Vanguard cautions that mineralization on adjacent properties is not necessarily indicative of mineralization on the Company's own projects.

About Paraguay

The Republic of Paraguay is an emerging mining jurisdiction in the heart of South America, bordered by Brazil, Argentina, and Bolivia.
