Volta Drills Widest TREO-Mineralized Interval to Date 0.95% TREO over 438.9m, Including 1.06% TREO over 358.6m, at Springer REE Project in Ontario, Canada

Executive Summary

• Volta Metals announced assay results from borehole SL25‑24 at the Springer Rare Earth Deposit, delivering a continuous 0.95 % TREO intercept over the full 438.9 m sampled interval to a depth of 465 m – the deepest hole drilled on the project to date.
• High‑grade zones were identified, including 1.42 % TREO over 108.1 m and 2.19 % TREO over 20 m, indicating a robust, bulk‑tonnage rare earth system that could substantially increase the forthcoming mineral resource estimate (targeted for early 2026).
• The results are expected to enhance the historic NI 43‑101 resource model (currently 4.2 Mt @ 1.14 % TREO indicated and 12.7 Mt @ 1.17 % TREO inferred) and support a material upward revision of both indicated and inferred resources.

Key Details

• Drill Hole: SL25‑24, sub‑vertical (‑85°), total depth 465 m; planned length 400 m but extended after visual core inspection.
• Overall Intercept: 0.95 % TREO over 438.9 m (26.1–465 m).
• High‑Grade Intercepts:
• 1.42 % TREO over 108.1 m (106.4–214.5 m).
• 2.19 % TREO over 20 m (155.5–175.5 m).
• Elemental Concentrations (selected):
• Heavy REEs: up to 10.6 g/t Tb, 50.2 g/t Dy in the 2.19 % zone.
• Light REEs: up to 2,606 g/t Y, 4,959 g/t Nd, 8,496 g/t Ce in the 2.19 % zone.
• Historical Resource Context: Historic 2012 estimate (non‑compliant with current CIM standards) – Indicated 4.2 Mt @ 1.14 % TREO; Inferred 12.7 Mt @ 1.17 % TREO, cut‑off 0.9 % TREO.
• Planned Follow‑Up: Assay results from a third borehole and gallium assays for the first two holes expected in coming weeks; resource update scheduled for Q1 2026.
• QA/QC: Diamond drilling with NQ‑size core, strict QA/QC protocol including certified REE standards, blanks, duplicates; samples processed by Activation Laboratories (Code 8‑REE assay).
• Qualified Person: Andrew Tims, P.Geo., independent QP under NI 43‑101.

Notable Quotes

“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… 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.” – Kerem Usenmez, President & CEO, Volta Metals Ltd.
