Volta Intersects 0.81% Total Rare Earth Oxide and 68.13 g/t Gallium Oxide over 688m at Springer REE Project in Ontario, Canada

HIGHLIGHTS SL26-35 contains the longest REE-Ga mineralized interval to date at Springer. Gallium and Rare Earth Elements are designated critical minerals by Canada, the U.S., and EU, vital to semiconductors, defense, and clean energy. At 688 metres ("m"), this is one of the longest mineralized intervals ever reported at a North American REE project, with grades that rank among the continent's best: 0.81% TREO and 68.13 g/t Ga 2 O 3 over 688 m, from 4.6 m to 693.0 m, including. 1.01% TREO and 79.02 g/t Ga 2 O 3 and over 210 m, from 366 m to 576 m.

The hole also significantly extends the REE-Ga mineralization approximately 180 m laterally and 260 m vertically from the current open pit shell. Premium magnet Heavy and Light Rare Earth Elements intersected include 7.1 m of: Terbium up to 23 g/t Tb 4 O 7 and Dysprosium up to 94 g/t Dy 2 O 3 . Gadolinium up to 255 g/t Gd 2 O 3 and Samarium up to 468 g/t Sm 2 O 3 .

Neodymium up to 3,063 g/t Nd 2 O 3 and Praseodymium up to 860 g/t Pr 6 O 11 . Toronto, Ontario--(Newsfile Corp. - June 8, 2026) - Volta Metals Ltd. (CSE: VLTA) (FSE: D0W) (OTCQB: VOLMF) (" Volta " or the " Company ") is pleased to announce drill core assay results from SL26-35, the longest drill hole of the 2026 winter drill program at its Springer Rare Earth Element deposit (the " Property "), near Sturgeon Falls, Ontario, Canada. Drill hole SL26-35 intersected a significant 688 m interval of Gallium and Rare Earth Element (" Ga-REE ") mineralization grading 0.81% Total Rare Earth Oxides (" TREO ") and 68.13 g/t Ga 2 O 3 from 4.6 m to 693.0 m depth.

From January to April 2026, Volta completed a 13-hole drill program at the Springer deposit (SL26-27 to 39) totalling 5,452 m. The drill program was designed to upgrade the current mineral resource estimate (" MRE ") through infill drilling, while also expanding the known REE-Ga mineralizatio
