Volta Drills Wide, High-Grade Rare Earth Oxide Mineralization at Springer REE Project in Ontario, Canada

Executive Summary

• First borehole (SL25‑23) at the Springer Rare Earth Deposit returned a significant TRE 0.85% over 383.5 m, including high‑grade zones of Praseodymium (up to 0.33%) and Neodymium (up to 0.96%).
• Premium heavy rare earths were intersected, notably Terbium up to 39 g/t and Dysprosium up to 154 g/t, with a peak TREO of 8.67% over 1.5 m.
• Results validate historic resource estimates and support an upcoming mineral‑resource update expected in Q1 2026.

Key Details

• Borehole SL25‑23: Drilled to 453 m (planned 350 m) at a –45° angle; core lengths reported (true widths pending).
• Overall TREO intercept: 0.85% TREO from 44 m to 427.5 m (383.5 m length).
• High‑grade intervals:
• 81–88 m: 3.01% TREO, 8.9 g/t Tb, 32.9 g/t Dy, 89 g/t Nd, 1,187 g/t Pr.
• 183.5–189 m: 3.82% TREO, 28.4 g/t Tb, 114.1 g/t Dy, 367 g/t Nd, 4,746 g/t Pr.
• 186–187.5 m: 8.67% TREO over 1.5 m, 39 g/t Tb, 154 g/t Dy, 500 g/t Nd, 7,080 g/t Pr.
• Other notable intervals: Multiple sections with TREO >1% and elevated LREE/HREE concentrations (see Table 1 for full list).
• Assay methodology: Activation Laboratories Ltd., Code 8‑REE assay (ICP/ICP‑MS) following strict QA/QC protocol (reference standards, blanks, duplicates).
• Future work: Assay results from second borehole expected within two weeks; resource model update scheduled for Q1 2026.
• Qualified Person: Andrew Tims, P.Geo., independent QP under NI 43‑101.

Notable Quotes

“We're very pleased with the outcome of our first Springer borehole,” said Kerem Usenmez, President and CEO of Volta. “Not only does it validate the historical resource, but it also confirms that high‑grade mineralization continues at depth… This strong start gives us great confidence in the remaining drillholes and the upcoming mineral resource update.”
