Volta Commences Definition Drilling and Resource Expansion Program at the Springer REE Project in Ontario, Canada

Executive Summary

• Volta Metals Ltd. has launched a fully funded, second‑phase winter drill program at the Springer Rare Earth Deposit in Ontario, targeting 16 diamond holes (~5,750 m) to be completed by Q1 2026.
• The Phase 2 work builds on strong Phase 1 results, including a high‑grade Dysprosium/Terbium interval (184 g/t Dy₂O₃+Tb₂O₃ over 27.1 m) and aims to infill historic drilling to 50 m spacing, expand mineralization, and collect geotechnical/geometallurgical data for a Preliminary Economic Assessment slated for 2026.
• Phase 1 drilling confirmed continuous REE mineralization (283–438 m thickness; 0.65‑0.95 % TREO) extending below the historic 2012 resource shell, supporting an upcoming update to that resource estimate in Q1 2026.

Key Details

• Program Scope: 16 diamond drill holes, total ~5,750 m; individual holes 300–400 m (final depths contingent on geology).
• Timeline: Drilling scheduled for completion in Q1‑2026.
• Objectives:
• Infill historic drilling to 50 m spacing.
• Expand known mineralization along strike and depth.
• Generate geotechnical, geometallurgical, and geological data for a 2026 PEA.
• Phase 1 Review (Sept 2025):
• Four holes, 1,638 m total.
• Continuous REE intervals 283–438 m; TREO grades 0.65‑0.95 %.
• High‑grade Dy/Tb interval: 184.04 g/t Dy₂O₃+Tb₂O₃ over 27.1 m (124.4‑151.5 m).
• HREO component averages 10.9 % of TREO; includes Dy, Tb, Y, Gd.
• Historical Resource (2012):
• Indicated: 4.2 Mt @ 1.14 % TREO (0.02 % ThO₂).
• Inferred: 12.7 Mt @ 1.17 % TREO (0.01 % ThO₂).
• Not compliant with current CIM standards; to be updated after Phase 2 results.
• Geophysical Context: Prior high‑resolution aeromagnetic/spectrometric survey identified the Springer deposit and a secondary target east of Lost Lake, both showing low magnetic signatures and thorium anomalies.
• Infrastructure: Property accessible via Trans‑Canada Highway 17; nearby rail lines, power generation stations, and proximity (~70 km) to Sudbury mining district.
• QA/QC Protocol: Diamond NQ‑size core, reference standards, blanks, duplicates; samples processed at Activation Laboratories Ltd. using Code 8‑REE assay (ICP/ICP‑MS).
• Qualified Person: Andrew Tims, P.Geo., independent QP under NI 43‑101.
