Volta Metals Ltd. (CSE: VLTA) has released assay results from the final three drill holes of its 2026 winter program at the Springer Rare Earth Element deposit near Sturgeon Falls, Ontario, completing a 13-hole campaign. Hole SL26-29 returned the highest-grade intercept of the program — 2.95m grading 7.54% total rare earth oxides (TREO) and 282.7 g/t gallium oxide — within a broader 165.3m interval averaging 1.36% TREO and 81.3 g/t gallium oxide. Mineralization remained open at depth beyond 400m below surface and extends 190m past the eastern boundary of the conceptual open pit, factors investors may be watching closely.

Key Points

  • Volta Metals Ltd. (CSE: VLTA, OTCQB: VOLMF, FSE: D0W)
  • SL26-29 delivered the 2026 program's highest-grade intercept: 2.95m at 7.54% TREO and 282.7 g/t gallium oxide, within a 165.3m interval grading 1.36% TREO
  • SL26-30 intersected a heavy rare earth enriched zone — 3.0m grading 278 g/t dysprosium oxide and 44 g/t terbium oxide; the company is targeting two updated mineral resource estimates in Q4 2026
  • Gallium mineralisation is present throughout full assayed lengths but is not included in the current Springer mineral resource estimate

Record-Grade Intercept Extends Springer Mineralisation Beyond Conceptual Open Pit

Drill hole SL26-29 tested the core of the Springer deposit, returning 412.5m averaging 0.85% TREO and 64.4 g/t gallium oxide from 7.5m to 420.0m. Within that broad envelope, a 165.3m interval graded 1.36% TREO and 81.3 g/t gallium oxide, and a 2.95m high-grade section returned 7.54% TREO and 282.7 g/t gallium oxide — the strongest rare earth and gallium result of the entire 2026 program. A sample near the bottom of the hole at 417.0m to 418.5m returned 1.97% TREO and 101.6 g/t gallium oxide, indicating the system remains open at depth and extends mineralisation approximately 190m beyond the eastern limit of the current conceptual open pit.

SL26-30 Highlights Dysprosium and Terbium Enrichment Critical for Permanent Magnets

Hole SL26-30 averaged 0.87% TREO and 67.6 g/t gallium oxide over 345.6m. A 26.8m zone grading 1.95% TREO and 104.6 g/t gallium oxide was identified between 114.2m and 141.0m, with heavy rare earth oxides comprising 18.2% of TREO over a 3.0m sub-interval. That interval returned 278 g/t dysprosium oxide and 44 g/t terbium oxide — both critical inputs for high-performance permanent magnets used in electric vehicle motors, wind turbines, and defence applications. The release states gallium mineralisation was continuous throughout the full assayed length of SL26-30.

Springer Deposit Context: Top-10 North American REE Deposit With Unresourced Gallium

The Springer deposit holds a current mineral resource estimate of 56.6 Mt Indicated at 0.70% TREO and 119.5 Mt Inferred at 0.58% TREO, prepared by SLR Consulting (Canada) Ltd. and effective December 31, 2025. The disclosure notes this places Springer among the top 10 largest rare earth deposits in North America per S&P Global Market Intelligence (2025). Gallium mineralisation — present throughout both SL26-29 and SL26-30 — is not included in the existing resource estimate. The company is targeting a maiden gallium mineral resource estimate and an updated rare earth mineral resource estimate, both in Q4 2026, subject to metallurgical work and consultant availability.

Gallium's Strategic Significance Amid Chinese Export Restrictions

The announcement highlights gallium's role in semiconductors, power electronics, and radar systems. The release states that China produces most of the world's gallium and restricts its export, adding strategic context for Springer's gallium endowment. Because gallium at Springer is not yet included in any resource estimate, its contribution to project value remains to be quantified. The immediate share price impact was not clear from available public information. Mineral resources are not mineral reserves and do not have demonstrated economic viability, as the company notes in its disclosure.
