# Volta raises Springer indicated rare earth resource to 122.4 million tonnes > Springer’s indicated rare earth resource in Ontario rose 116% to 122.4 million tonnes. A first supplementary gallium estimate reports in-situ content, but assigns gallium no economic value. - Canonical URL: https://newsverum.com/en/news/volta-springer-rare-earth-resource-expands-gallium-estimate-2026 - Publisher: Newsverum - Section: Business - Country: Canada - Published: 2026-10-20T23:01:24+00:00 - Updated: 2026-10-20T23:01:24+00:00 - Event / data period: 2026-10-19 - Other editions: [Türkçe](https://newsverum.com/tr/news/volta-springer-rare-earth-resource-expands-gallium-estimate-2026.md), [العربية](https://newsverum.com/ar/news/volta-springer-rare-earth-resource-expands-gallium-estimate-2026.md), [Français](https://newsverum.com/fr/news/volta-springer-rare-earth-resource-expands-gallium-estimate-2026.md), [Español](https://newsverum.com/es/news/volta-springer-rare-earth-resource-expands-gallium-estimate-2026.md), [Deutsch](https://newsverum.com/de/news/volta-springer-rare-earth-resource-expands-gallium-estimate-2026.md), [Português](https://newsverum.com/pt/news/volta-springer-rare-earth-resource-expands-gallium-estimate-2026.md) Volta Metals said an independent estimate effective September 30, 2026 puts Springer’s indicated resource at 122.4 million tonnes grading 0.59% total rare earth oxides (TREO). The company also reported 197.5 million tonnes at 0.53% TREO in the inferred category; the indicated high-grade core is 27.6 million tonnes at 1.00% TREO. The release gives a supplementary gallium estimate averaging 36 grams per tonne within the resource volume, including 14.8 million tonnes at 56 grams per tonne in the high-grade domain. Gallium has no assigned economic value in the current estimate because recovery to a saleable product, costs and payability are not established. Mineral resources are not reserves and do not demonstrate economic viability. ## Data ### Springer rare earth and gallium estimate Independent resource estimate for the Springer deposit in Ontario, effective September 30, 2026, plus a supplementary gallium estimate with no established economic value. Methodology: Mineral Resource Estimate prepared by SLR Consulting (Canada) Ltd. and effective September 30, 2026 according to the issuer. The gallium figure is an in-situ supplementary estimate within the rare earth resource volume, not a standalone gallium resource; it does not establish recovery, a saleable product or economic value. Mineral resources are not reserves and do not demonstrate economic viability. | label | value | unit | period | basis | |---|---|---|---|---| | Indicated rare earth resource: tonnage | 122.4 | million tonnes | 2026-09-30 | estimate | | Indicated rare earth resource: TREO grade | 0.59 | % | 2026-09-30 | estimate | | Inferred rare earth resource: tonnage | 197.5 | million tonnes | 2026-09-30 | estimate | | Inferred rare earth resource: TREO grade | 0.53 | % | 2026-09-30 | estimate | | Gallium: average in-situ grade | 36 | g/t | 2026-09-30 | estimate | Sources: · Download data: [JSON](https://newsverum.com/api/v1/articles/volta-springer-rare-earth-resource-expands-gallium-estimate-2026/data/volta-springer-rare-earth-gallium-estimate?lang=en&format=json) · [CSV](https://newsverum.com/api/v1/articles/volta-springer-rare-earth-resource-expands-gallium-estimate-2026/data/volta-springer-rare-earth-gallium-estimate?lang=en&format=csv) ## Sources - [Volta Metals Ltd. via TMX Newsfile]() (Source checked: 2026-10-21; Published: 2026-10-19) --- Cite the canonical URL above.
