Vanguard Mining receives Yuty Prometeo licence

Executive Summary

• Vanguard Mining Corp. has secured a prospection permit from the Ministerio del Ambiente y Desarrollo Sostenible (MADES) for its Yuty Prometeo uranium project in Paraguay, marking a key step toward full exploration and development approvals.
• The company’s technical advisers visited the Vice Ministerio de Minas y Energia core shed in Asuncion on October 29, 2025, to review core samples in preparation for upcoming exploration activities.
• The Yuty Prometeo project spans approximately 90,000 hectares adjacent to Uranium Energy Corp.'s (UEC) established Yuty deposit, which hosts an indicated resource of 8.96 million pounds of U3O8.

Key Details

• Regulatory Milestone: Vanguard received its environmental licence and prospection permit from MADES, derisking the path toward full exploration and development authorization for the Yuty Prometeo project.
• Project Location & Size: The project consists of four concessions (three San Jose and one Prometeo) spanning approximately 90,000 hectares (222,395 acres) in the Parana basin, southeastern Paraguay.
• Prometeo Concession Details:
  • Spans approximately 27,666 hectares (68,368 acres).
  • Directly contiguous to UEC's Yuty project.
  • Historical records reference 28 drill holes with uranium values ranging from 0.05% to 0.10% U3O8.
  • Data suggests the block lies on trend with UEC's adjacent Transandes block.
• San Jose Concession Details:
  • Encompasses approximately 62,210 hectares (153,754 acres) across three contiguous claims.
  • Located along the Upper Permian-Carboniferous contact, ~100 km northwest of UEC's Yuty project and 40 km west of its Coronel Oviedo project.
  • A radiometric car survey over a 40km x 10km area delineated significant uranium anomalies.
• Adjacent Neighbor Resource (UEC):
  • UEC's Yuty ISR project spans ~117,359 hectares.
  • Indicated Resource: 8.962 million pounds U3O8 (9,074,000 tons grading 0.049% U3O8).
  • Inferred Resource: 2,203,000 pounds U3O8 (2,733,000 tons grading 0.040% U3O8).
• Historical Data Disclaimer: Historical drill results on Vanguard's property have not been independently verified under NI 43-101; the company plans to complete confirmatory drilling to verify this information.
• Technical Review: On Oct. 29, 2025, technical advisers reviewed core from the project at the Vice Ministerio de Minas y Energia core shed in Asuncion.

Notable Quotes

• David Greenway, CEO: "Securing the MADES prospection permit is a key milestone that advances the Yuty Prometeo uranium project and strengthens our pipeline of high-value uranium assets in Paraguay. This approval meaningfully derisks our path toward full exploration and development authorization."
