Volta confirms gallium down the full hole at Springer
Three more holes stayed mineralized to 504 m and carried gallium the whole way. The stock rose 84% over three months while rare-earth peers fell.
On September 15, 2026, Volta Metals reported three more drill holes from its Springer rare-earth and gallium project near Sturgeon Falls, Ontario. The press release led with 7.37% total rare earth oxides (TREO — the combined weight of the rare-earth metals in the rock) and 252.7 grams per tonne gallium oxide. That headline came from a single 1.5-metre sample, so treat it as eye-candy, not the story. The real result: hole SL26-28 stayed mineralized over 417 metres running 0.566% TREO, and gallium ran the full length of all three holes. When we last covered Springer, grade was firming up as the drill went deeper. This time the message is length and consistency.
Here is why that matters. Springer is a bulk-tonnage carbonatite — a big body of modest-grade rock — so the number that counts is grade times thickness, not a single rich streak. SL26-28’s full 417 metres scores about 236 %-metres of contained metal; a broader 214.5-metre envelope inside it ran 0.795%. It stayed mineralized to 504 metres down, confirming the system runs deep. SL26-34 and SL26-36 pushed mineralization into gneiss and syenite rock previously thought barren, growing the footprint — though the release does not state how far the zone was extended, and these are separate collars, not linked holes. Grades sit at or below the existing 0.70% TREO resource core, so this expands scale rather than lifts grade. Gallium sits entirely outside the current resource, which makes a maiden gallium estimate real added optionality. The stock rose 83.8% over three months while the rare-earth benchmark REMX fell 29.3% — a 113-point gap that rules out any sector tailwind.
Now the honest part. True widths aren’t stated — these are downhole core lengths, so the real thickness may be less. No downhole directional survey was run, so the geometry of that 504-metre persistence carries positional uncertainty. SL26-28 is an infill hole between existing holes, so it confirms continuity rather than steps out. No metallurgical work yet shows gallium is economically recoverable. Our prior entry’s open items: the remaining assays are still arriving from SRC (holes SL26-29, -30 and -38 are pending), and the company targets Q1 2027 for the updated resource plus initial gallium estimate.
