Volta confirms 236.6 g/t Ga2O3 and 6.41% TREO at Springer

HIGHLIGHTS

Gallium mineralization extends significantly beyond the currently defined main rare earth mineralized zones, demonstrating a broader gallium distribution.

Gallium mineralization extends vertically 210 m past the outline of the current open pit in both SL26-31 and SL26-33, and SL26-32 ends in mineralization at 426 m and remains open at depth, indicating resource growth potential beyond the current pit-constrained estimate.

51.8 g/t Ga₂O₃ over the entire 399.0 m length of drill hole SL26-31 (3.0-402.0 m).

The highest gallium interval of the three holes is: 236.6 g/t Ga₂O₃ and 6.41% TREO over 0.5 m (67.1-67.6 m) in SL26-31, also containing Premium Magnet Rare Earths: 6,730 g/t Neodymium oxide (Nd₂O₃), 2,598 g/t Praseodymium oxide (Pr₆O₁₁), 414 g/t Samarium Oxide (Sm₂O₃), and 265 g/t Gadolinium oxide (Gd₂O₃).

SL26-32 intersected 1.22% TREO and 47.0 g/t Ga₂O₃ over 53.9 m (372.1-426.0 m), extending to the bottom of the hole, which ended in mineralization.

Gallium is not included in the current Springer mineral resource estimate.

Toronto, Ontario--(Newsfile Corp. - August 10, 2026) - Volta Metals Ltd. (CSE: VLTA) (FSE: D0W) (OTCQB: VOLMF) ( " Volta " or the " Company ") announces assay results from drill holes SL26-31, SL26-32 and SL26-33, completed as part of the 2026 winter drill program at its Springer Rare Earth Element deposit (the " Property "), near Sturgeon Falls, Ontario, Canada.

"The gallium story at Springer continues to strengthen with every drill hole. What is most compelling is that gallium is not confined to the higher-grade rare earth mineralization. It is broadly distributed throughout the host rocks across the deposit, giving us confidence that the gallium footprint may ultimately extend beyond the current rare earth resource. Contingent on positive metallurgical confirmation, this supports our object
