Volta Metals drills 438.9 m of 0.95% TREO at Springer

Executive Summary

• Volta Metals Ltd. released assay results from the second borehole (SL25-24) at its Springer Rare Earth Project in Ontario, Canada, identifying the widest TREO-mineralized interval to date.
• The results significantly exceed expectations, confirming continuous, high-grade mineralization over a 438.9-meter interval and extending the known deposit to a depth of 465 meters, which is the deepest borehole completed on the project.
• These findings support the company's confidence in a robust, extensive rare-earth system and will contribute to a forthcoming mineral resource update planned for early 2026.

Key Details

• Primary Intercept: 0.95% TREO over 438.9 meters.
• High-Grade Sub-Interval: 1.06% TREO over 358.6 meters within the primary intercept.
• Deepest Borehole Details: Borehole SL25-24 was drilled subvertical (negative 85 degrees) to a total depth of 465 meters. It returned significant mineralization (0.95% TREO) over the entire sampled interval from 26.1 meters to 465 meters.
• High-Grade Intervals:
  • 1.42% TREO over 108.1 meters.
  • 2.19% TREO over 20 meters.
• Geological Significance: The mineralization includes both light and heavy rare-earth elements. The consistency and scale suggest a robust system comparable to large bulk-tonnage base metal deposits rather than narrow zones typically associated with rare earths.
• Historic Resource Context: The new data will be incorporated into an update of the historic NI 43-101 resource estimate (Daigle P., May 4, 2012), which previously defined an indicated resource of 4.167 Mt at 1.073% TREO and an inferred resource of 12.73 Mt at 1.119% TREo (at a 0.9% cut-off).
• Future Plans: The company expects to receive assay results from the third borehole and gallium assays from the first two boreholes in the coming weeks.
• QA/QC: Samples were analyzed by Activation Laboratories Ltd. using code 8-REE assay (lithium metaborate/tetraborate fusion with ICP/MS analysis).

Notable Quotes

• "This second borehole, the deepest completed to date, successfully tested the footwall beneath the historical resource and returned continuous, high-grade TREO mineralization throughout its entire length," said Kerem Usenmez, president and chief executive officer of Volta Metals. "The consistency and scale of mineralization we're seeing, suggest a robust and extensive rare-earth system -- geologically more comparable to large bulk-tonnage base metal deposits than to the narrow zones typically associated with rare earths. These results reinforce our confidence that Springer hosts a much larger mineralized system than previously understood, which will be reflected in the upcoming mineral resource update."
