Volta Reports Additional High-Grade Gallium Mineralization at Springer REE Project

HIGHLIGHTS

• Gallium mineralization extended to 191.5m in Drill hole SL25-23, remains open with further gallium assays pending:

  • 81g/t Ga₂O₃ (plus 1.4% TREO) over 131.9m (from 59.6m to 191.5m)

  • Including 110 g/t Ga₂O₃ (plus 2.5% TREO) over 15.7m (from 175.8m to 191.5m)

  • Up to 332.0 g/t Ga₂O₃ over 1.0m (from 82.0m to 83.0m)

• Results rank among the highest-grade and continuous gallium assays reported in North America

Toronto, Ontario--(Newsfile Corp. - February 11, 2026) - Volta Metals Ltd. (CSE: VLTA) (FSE: D0W) (OTC Pink: VOLMF) ("Volta" or the "Company") reports additional gallium assay results from its Springer Rare Earth Project near Sturgeon Falls, Ontario, Canada. The newly received assays from drill hole SL25-23 confirm the extension of high-grade gallium mineralization over a 131.9m interval grading 81.2 g/t Ga₂O₃ (Figure 1).

The sampled interval (59.6m to 285m) ended in 40.1 g/t Ga₂O₃ from 283.5 to 285m with additional gallium assay results pending from drill hole SL25-23. Previously, hole SL25-23 returned 0.85% Total Rare Earth Oxides ("TREO") over 383.5m (from 44.0m to 427.5m) with a higher-grade interval of 1.11% TREO over 197.5m, including 1.64% TREO over 69.5m (Volta press release dated October 29, 2025).

These additional Springer results confirm the continuity of high-grade gallium mineralization and strengthen the project's positioning as a leading gallium-bearing Rare Earth Element ("REE") system in North America. (Table 1).

Gallium is primarily produced as a by-product of aluminum and zinc refining, making primary natural gallium occurrences uncommon. Industry benchmarks generally classify gallium grades as:

• Low grade: 2O₃

• Moderate grade: 35 to 60 g/t Ga₂O₃

• High grade: >60 g/t Ga₂O₃

These ongoing results represent the widest and most consistent high-grade gallium intercepts identified at Springer to date and demonstrate the project's multi-commodity critical mineral potential in addition to its high-grade REE mineralization.

Company has retained SLR Consulting (Canada) Ltd, Toronto, Ontario to update the resource estimate including the recently completed 2025 drill program, and the resource update is expected to be completed by the end of February 2026.

"These new gallium results further confirm the scale and continuity of mineralization at Springer," said Kerem Usenmez, President and CEO of Volta. "Long, consistent intervals of high-grade gallium are rare in North America, particularly outside of by-product operations. With global gallium supply constrained and demand accelerating for AI chips and advanced electronics-where the market is expected to grow roughly tenfold over the next decade-Springer continues to demonstrate its strategic importance and growing value. This progress comes as we advance toward an upcoming rare earth resource update, which we view as a key near-term catalyst for the project."

About the Springer Rare Earth Deposit

The 2012 mineral resource estimate presented for the Springer Rare Earth Project is historical in nature. Volta's Qualified Person has not completed sufficient work to confirm the results of the historical resource. Volta does not treat this as a current mineral resource but considers it relevant as a guide to future exploration and includes it for reference purposes only. The historical resource was estimated by Tetra Tech Wardrop in 2012. Gallium was not included in this initial mineral resource estimate.

The block model and mineral resource for the Springer Rare Earth Project is classified as having both Indicated and Inferred Mineral Resources based on the number of boreholes, borehole spacing and sample data populations used in the estimation of the blocks. The mineral resource estimate for the deposit, at a 0.9% TREO cut-off, is an Indicated Resource of 4.2 Mt at 1.14% TREO, 0.02% ThO_2, with approximately 6% of the TREO being made up of Heavy Rare Earth Oxides ("HREO"); and an Inferred Resource of 12.7 Mt at 1.17% TREO, 0.01% ThO_2, with approximately 4% of the TREO being made up of HREOs.

The 2012 mineral resource, based on 22 diamond boreholes, was estimated by Ordinary Kriging interpolation on uncapped grades for all 15 REOs and thorium dioxide. The TREO% is a sum of the 15 individual interpolations of the REOs. No recoveries have been applied to the interpolated estimates.

The 2012 mineral resource estimate categories are not compliant with the current CIM Definition Standards. No other resource estimates have been disclosed since the 2012 Tetra Tech Wardrop report. Further drilling will be required by Volta to verify the historical estimate as a current mineral resource.

QA/QC Protocol

All drilling was completed by a diamond drill rig producing NQ-size core. Volta implemented a strict QA/QC protocol in processing all rock samples collected from the diamond core samples obtained from the Springer REE property. The protocol included inserting reference materials, in this case, high-concentration and low-concentration certified rare earth elements standards, blanks, and drill core duplicates, to validate the accuracy and precision of the assay results. All collected rock core samples were cut in half by a rock saw, placed in sturdy plastic bags and zip-tied shut while under the supervision of a professional geologist. The remaining half core was returned to the core box, which is stored on the Property. Sample bags were then put in rice bags and kept secure before being sent by road transport to Activation Laboratories Ltd.'s ("ActLabs") preparation facility in North Bay, Ontario. Sample preparation (code RX1) consists of drying and crushing (
