The update includes a first-time supplementary gallium estimate of 4,427 tonnes in the Indicated category. While overall grades for rare earth oxides have decreased, the significant increase in tonnage and improved net metal revenue position Springer as one of North America's largest rare earth deposits. Reasoning: Volta Metals has announced a substantially expanded Mineral Resource Estimate for its Springer project, significantly increasing both Indicated and Inferred rare earth tonnages and introducing a new gallium estimate. While overall grades have decreased, the substantial volume increase and improved net metal revenue are positive, positioning Springer as a major North American rare earth deposit. The economic viability of gallium still requires further metallurgical work. - Positive factor: Significant increase in Indicated and Inferred resource tonnage - Positive factor: First-time supplementary gallium estimate - Positive factor: Expansion of high-grade core - Positive factor: Low conceptual strip ratio of 1.26 - Positive factor: Excellent existing infrastructure \(Trans-Canada Highway, power, gas, rail\) - Positive factor: NI 43-101 compliant and QP signed off - Negative factor: Overall grade decline in TREO and MREO for both Indicated and Inferred categories - Negative factor: Gallium estimate not yet assigned economic value due to preliminary metallurgical test work - Negative factor: REO recovery assumptions based on bench-scale test work on a single master composite, requiring further validation - Negative factor: Historical density measurements not supported by laboratory certificates - Negative factor: Comparison to previous estimate uses different technical and economic assumptions, complicating direct reconciliation Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 88 ## Classification and evidence **Tonnage Growth** Polarity: positive Definition: Significant tonnage increase \(≥15%\) vs prior estimate with grade maintained or improved. Why it applies: Indicated tonnage increased by 116% from 56.6 Mt to 122.4 Mt, and Inferred tonnage increased by 65% from 119.5 Mt to 197.5 Mt. Evidence · text > Indicated Mineral Resources increased 116% to 122.4 Mt grading 0.59% TREO, up from 56.6 Mt in February 2026. Inferred Mineral Resources increased 65% to 197.5 Mt grading 0.53% TREO. **Maiden Resource** Polarity: neutral Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. Why it applies: This is the first supplementary gallium estimate for the project. Evidence · text > Delivers First Gallium Estimate **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard.

Other scientific and technical information in this news release has been reviewed and approved by Dr. Julie Selway, P.Geo., VP Exploration, and a Qualified Person \("QP"\) as defined in National Instrument 43-101, Standards of Disclosure for Mineral Projects . **Cut-off Disclosed** Polarity: positive Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison. Why it applies: The open pit Mineral Resources are reported within an optimized pit shell and above a C$43/t net metal revenue \(NMR\) cut-off. Evidence · text > Open pit Mineral Resources are reported within an optimized pit shell and above a C$43/t net metal revenue \(NMR\) cut-off. **Grade Decline** Polarity: negative Definition: Average grade dropped >5% vs prior estimate — deposit economics worsening. May indicate high-grading in early drilling. Why it applies: Indicated TREO decreased from 0.70% to 0.59% \(-16%\), and Inferred TREO decreased from 0.58% to 0.53% \(-9%\). Evidence · text > Indicated TREO decreased from 0.70% to 0.59%, and Inferred TREO decreased from 0.58% to 0.53%. **Refractory Ore** Polarity: negative Story-specific tag Definition: Ore requires oxidation/pressure treatment before recovery — a processing and recovery risk. Why it applies: Gallium is not yet assigned economic value because available metallurgical test work has not established overall recovery to a saleable gallium product, processing costs, or commercial payability. Evidence · text > Gallium is assigned no economic value because available metallurgical test work has not established overall recovery to a saleable gallium product, processing costs, or commercial payability. **Bench Scale Only** Polarity: negative Story-specific tag Definition: Only preliminary bench tests completed — no locked-cycle or pilot work.

Evidence · text > As reported in Volta's June 1, 2026 news release, the recovery assumptions are based on bench-scale test work completed by SGS Canada Inc. \(SGS\) on a single master composite from Springer. The results are preliminary and do not demonstrate recovery to a saleable product or consistent recovery across the deposit. Additional test work is required to confirm these assumptions. **Stale Estimate** Polarity: negative Definition: Effective date is >2 years old — data currency concern, may not reflect current geological understanding. Why it applies: The North American ranking is based on a third-party database dated May 2025, which may not reflect the most recent estimates of other projects. Evidence · text > The North American ranking is based on a third-party database dated May 2025 that may not reflect the most recent estimates of other projects. ## Extracted facts Stored fact records: 88.

Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
