Volta Delivers Positive Initial Metallurgical Results at Springer

Springer metallurgical results confirm low-cost processing and gallium upside, but liquidity pressures mount ahead of June option payments.

Executive Summary

Volta Metals announced initial bench-scale flotation test results for its Springer Rare Earth Element (REE) Deposit in Ontario.
SGS Canada completed 11 tests, achieving 88.2% total REE recovery and up to 13x enrichment.
Testing identified a simple, cost-effective crush-grind-float flowsheet using conventional froth flotation.
Effective mineral liberation was achieved at a coarse grind size of -106 µm, which is significantly coarser than peer projects requiring ≤-53 µm, implying lower grinding OPEX.
Gallium was identified as a dual-host by-product recoverable from REE concentrate (synchysite) and flotation tailings (feldspars), adding strategic value amid global supply constraints.
Results materially exceed conservative recovery assumptions from the company's historic 2012 mineral resource estimate.
Administrative update: 180,000 RSUs granted to officers under the Long-Term Incentive Plan.
Next phase of metallurgical work will focus on detailed mineralogical characterization, circuit optimization, and reagent refinement.

Material Impact

The June 1, 2026 metallurgical results serve as a critical validation of the February 2026 resource expansion and the January 2026 high-grade gallium drilling intercepts.
The confirmation of a simple, ambient-temperature flotation circuit with a coarser grind requirement de-risks the processing pathway and materially improves confidence in the project's economic potential ahead of the targeted Preliminary Economic Assessment (PEA) in late 2026.
The identification of gallium as a recoverable by-product introduces a potential revenue diversification avenue, particularly relevant given China's dominance (~80%) in global gallium supply.
While the results are fundamentally positive and exceed historic benchmarks, they represent an expected, sequential milestone in the project's development lifecycle rather than a sudden paradigm shift. The metallurgical work logically follows the completed Phase-2 drill program and resource estimation.
Therefore, the market-moving potential is incremental. The company continues to execute on its exploration roadmap without introducing unexpected financial or operational catalysts at this stage.

Company Overview

Volta Metals Ltd. is an exploration-stage Canadian critical minerals company focused on Rare Earth Elements (REEs), gallium, and lithium.
Flagship asset: Springer REE and Gallium Project, located approximately 70 km east of Sudbury, Ontario, on the traditional territory of the Nipissing First Nations.
Property size: 4,750 hectares.
Geology: Hosted within a structurally intact, mantle-rooted carbonatite pipe surrounded by syenite-fenitized breccias. Primary REE host mineral is synchysite.
Infrastructure: Favorable location with paved road access (Highway 64), nearby hydroelectric power (Crystal Falls dam), natural gas pipeline, and Canadian National Railway service within 8 km.
The project is positioned to supply both Light Rare Earth Elements (LREEs) like Praseodymium and Neodymium, and Heavy Rare Earth Elements (HREEs) like Dysprosium and Terbium, alongside strategic gallium.
