Volta's last Springer holes land — 165.3m of rare earths, deep and east
The final winter assays confirm a ~1% rare-earth core over hundreds of metres and push mineralization 190m east to depths of 131–296 m below surface. The company targets twin resource estimates for Q4.
On October 1, 2026, Volta Metals reported the last assays from its 13-hole winter drill program at Springer, its rare-earth and gallium project near Sturgeon Falls, Ontario. The headline hole, SL26-29, cut 165.3 metres running 1.363% total rare earth oxides (TREO — the combined weight of rare-earth metals in the rock) with 81.3 grams per tonne gallium oxide, including a sharper 2.95-metre slice at 7.537%. A second hole, SL26-30, ran 109.5 metres at 1.328% TREO, with a heavy-rare-earth streak carrying 278 grams per tonne of dysprosium oxide over 3 metres. When we last covered Springer, the story was length and consistency down the hole; this release closes out the pending assays — SL26-29, -30 and -38 — that we flagged as still arriving from the lab.
Here is why that matters. Springer is a bulk-tonnage carbonatite — a big body of modest-grade rock already sized at 176 million tonnes — so the number that counts is grade times thickness, not one rich streak. SL26-29 does two useful things. It confirms the roughly 1% TREO core holds together over hundreds of metres, and it extends mineralization about 190 metres east of the current conceptual pit, with the 165.3-metre interval sitting between 131 and 296 metres below surface. That de-risks the deposit’s scale and depth. The heavy rare earths (dysprosium, terbium) and the gallium add value the current resource does not yet capture. The stock rose 29.2% over three months while the rare-earth benchmark REMX fell 28.2% — a 57-point gap that rules out any sector tailwind, with a decisive breakout from about 0.19 to 0.37 mid-period before settling near 0.31.
Now the honest part. The headline TREO is driven by cheap cerium and lanthanum; the magnet metals that carry most of the value are only about 16 to 25% of the total, so a big TREO number overstates magnet-metal worth. True widths aren’t stated — these are downhole core lengths, so real thickness may be less. No downhole directional survey was run, so the depth figures rest on collar geometry, not survey. SL26-38 in the southern deposit returned 89.2 metres at 0.526%, below the resource-average grade, showing the body isn’t uniformly rich. And gallium still sits outside the resource pending metallurgical recovery work. Two things to watch next: the company targets a maiden gallium resource and an updated REE resource, both for Q4 2026, followed by a preliminary economic assessment by year-end.
