Volta Completes Inaugural Drill Program at Springer REE Project in Ontario, Canada

Executive Summary

• Volta Metals announced high‑grade rare earth intercepts from four new boreholes (SL25‑23, SL25‑24, SL25‑25, SL25‑26) at the Springer Rare Earth Deposit, extending mineralization beyond the 2012 resource shell.
• Notable heavy rare earth (HRE) grades include 157.8 g/t Dysprosium oxide and 26.2 g/t Terbium oxide over 27.1 m in hole SL25‑24, and multiple intervals with >10 % TREO over hundreds of metres.
• The results support an upcoming NI 43‑101 resource update slated for early 2026 and highlight a significant HRE component (≈11 % of TREO value).

Key Details

• Hole SL25‑24: 0.95 % TREO over 438.9 m; includes 1.09 % TREO over 351.1 m; high‑grade HRE interval of 157.8 g/t Dy₂O₃ and 26.2 g/t Tb₂O₃ over 27.1 m (124.4–151.5 m).
• Hole SL25‑23: Continuous mineralization 0.89 % TREO over 383.5 m; includes 1.71 % TREO over 69.5 m; multiple high‑grade HRE zones.
• Hole SL25‑26: 0.65 % TREO over 283.8 m (entire hole); 0.94 % TREO over 100 m; high‑grade section 1.07 % TREO over 13 m.
• Hole SL25‑25: Lower overall grade 0.38 % TREO but contains a 3.41 % TREO interval over 2.2 m (88.2–90.4 m).
• Heavy Rare Earth Content: HREOs (Dy, Tb, Y, Gd) average 10.9 % of total TREO value across the program; specific high‑grade HRE intercepts listed in Table 2.
• Light Rare Earth Content: Significant LREE grades (Nd, Pr, La, Ce) reported; e.g., SL25‑24 shows 4,910 g/t Nd₂O₃ and 1,467 g/t Pr₂O₃ over a 5.8 m interval.
• Depth Extension: All holes extend below the 2012 resource shell; deepest hole (SL25‑24) reaches 465 m, the deepest to date on the project.
• Assay Status: Gallium assays pending for all four boreholes.
• Resource Implication: Results will be incorporated into a planned update of the historical NI 43‑101 resource estimate (4.167 Mt @ 1.073 % TREO indicated; 12.73 Mt @ 1.119 % TREO inferred).
• CEO Quote: “These drill results validate our view that the Springer deposit represents a rare convergence of location, grade, scale, and mineralogy… marks an important step forward as we move toward updating the mineral resource estimate in early 2026.” – Kerem Usenmez, President & CEO.

Notable Quotes

• Kerem Usenmez, CEO: “These drill results validate our view that the Springer deposit represents a rare convergence of location, grade, scale, and mineralogy—an increasingly scarce combination globally… The expansion of high‑grade TREO at depth… has the potential to fundamentally reshape the project's trajectory ahead of the upcoming NI 43‑101 resource update.”
