Vanguard Mining to Launch Phase 1 Exploration at Nucleon Uranium Project Along the PLS-Arrow Discovery Corridor

Executive Summary

• Vanguard Mining Corp. announced the commencement of Phase 1 exploration at its Nucleon Uranium Project in Saskatchewan’s Athabasca Basin.
• The initial program, managed by Hardline Exploration Ltd., will conduct a lake‑sediment geochemical survey across seven mineral claims (23,425 ha) to identify and rank uranium‑bearing systems, at an estimated cost of C$25,000.
• No modern exploration has previously been performed on the Nucleon claims, giving Vanguard a “blue‑sky” opportunity to generate drill targets in a highly prospective district adjacent to major discoveries (Fission’s PLS and NexGen’s Arrow).

Key Details

• Project Scope: 7 mineral claims organized into four priority prospect areas covering 23,424.90 ha.
• Exploration Partner: Hardline Exploration Ltd., responsible for program design, execution, data interpretation, and target generation.
• Phase 1 Activities (Winter 2025):
• Systematic lake‑sediment sampling across all claim blocks.
• Multi‑element geochemical analysis targeting uranium and pathfinder elements.
• Anomaly mapping and prospect ranking to select high‑priority targets for follow‑up work.
• Budget: Estimated C$25,000 for the Phase 1 lake‑sediment survey.
• Future Work (post‑Phase 1): Anticipated radiometric surveys, additional geochemical sampling, geophysics, drill target definition, permitting, and First Nations consultation, culminating in drilling of refined targets.
• Strategic Context: Nucleon lies within the western Athabasca discovery corridor near Fission Uranium’s Patterson Lake South (PLS) and NexGen Energy’s Arrow deposits—two of the world’s most significant recent uranium discoveries.
• Qualified Person: Lawrence Segerstrom, consulting geologist, reviewed and approved the technical information per NI 43‑101 standards.

Notable Quotes

“The Nucleon Project gives Vanguard a commanding position along one of the world’s most important uranium discovery corridors… By starting with a disciplined geochemical screening program … we are building a technically sound pathway toward defining high‑quality drill targets while managing risk and capital efficiently.” – David Greenway, CEO
