Volta Drills Completes Inaugural Drill Program at Springer REE Project in Ontario, Canada
Press Release
DRILL PROGRAM HIGHLIGHTS
⦁ Borehole SL25-24 is one of the widest drill intercepts for rare earths globally: o 0.95% TREO over 438.9m (from 26.1m to 465.0m, end of hole)
o Including 1.09% TREO over 351.1m (from 106.4m to 457.5 m)
o 157.8 g/t Dysprosium oxide and 26.2 g/t Terbium oxide over 27.1m (from 124.4m to 151.5m)
⦁ Borehole SL25-23 is TREO mineralized over the entire hole:
⦁ 0.89% TREO over 383.5m (from 44.0m to 427.5m, end of hole)
⦁ Includes 1.71% TREO over 69.5m of
⦁ Multiple intervals of high-grade HREO and LREO
⦁ Borehole SL25-26 is TREO mineralized over the entire hole:
⦁ 0.65% TREO over 283.8m (7.5m to 291.3m, end of hole).
⦁ 0.94% TREO over 100m (from 12.5m to 112.5m)
⦁ Mineralization remains open at depth and along strike
⦁ Gallium assays are still outstanding on all four boreholes
Volta Metals Ltd. (CSE: VLTA) (FSE: D0W) (OTC Pink: VOLMF ) (“Volta” or the “Company”) announces assay results from the remaining boreholes drilled at its Springer Rare Earth Deposit (the “Property ”), located near Sudbury, Ontario, Canada (Figure 1). Drill results continue to expand known mineralization that remains open at depth in all boreholes to date.
All boreholes reported continuous mineralization, extending below the 2012 mineral resource estimate shell. Additionally, there have been increased heavy rare earth intercepts over wide intervals. Specifically, borehole SL25-24 returned a very high-grade Dysprosium and Terbium oxide interval of 184.04 g/t Dysprosium oxide + Terbium oxide (157.8 g/t Dy₂O₃ and 26.22 g/t Tb2O3) over 27.1m (from 124.4m to 151.5m) (Table 2). Dysprosium (Dy) and Terbium (Tb) are high-value, heavy rare earth elements critical for making high-performance permanent magnets used in electric vehicle motors, wind turbine generators, and industrial robotics. Current average quoted spot prices for Dy oxide and Tb oxide are US $180,000/tonne and US$802,000/tonne, respectively (Shanghai Metals Market average pricing, December 3, 2025).
Results from this drill campaign confirm a significant Heavy Rare Earth Oxides (“HREO”) component within the Total Rare Earth Oxides (“TREO”). HREOs constitute an average of 10.9% of the overall TREO basket value of the latest drill program results, primarily including Dysprosium, Terbium, Yttrium, and Gadolinium. The high-grade TREOs also include the light rare earth elements Praseodymium, Neodymium, Lanthanum, Cerium, and Samarium (Tables 1, 2 and 3).
