Vulcan Energy's Re-Injection Test Clears Its Own Hurdle as Bank Stakes Shift
Published on 10/29/2026 at 09:30 | Editorial boerse-global.de
Vulcan Energy has reported that testing at its LSC-3a re-injection well supports reinjection into the sandstone reservoir matrix — a core assumption underpinning the Lionheart field development plan. The modelled injection capacity came in at roughly 64 litres per second, against the approximately 40 litres per second the development plan had assumed for this configuration. That is a modelled figure, not a measured flow rate, but it sits comfortably above the design basis.
The company disclosed the result around two weeks ago and tied it directly to that specific precondition of the project, saying the outcome bolsters confidence in the Lionheart plan.
Separately, Vulcan confirmed the start of commercial VULSORB production in Germany. VULSORB is the company's lithium-selective adsorbent used for the project — the announcement covers manufacture of the adsorbent itself, not the launch of commercial lithium output at Lionheart.
Should investors sell immediately? Or is it worth buying Vulcan Energy?
Two filings, two different yardsticks
On the shareholder register, Citigroup disclosed a combined position of voting rights and financial instruments of 6.03%, up from 4.19%, a little over a week ago. Citigroup Global Markets Limited was named as the direct holder. The total breaks down into 5.82% of voting rights and 0.21% held through financial instruments — meaning the headline figure is not equivalent to a pure voting-rights stake.
JPMorgan Chase & Co. and affiliated entities also filed a voting-rights position in Vulcan Energy Resources. According to media reports, that stake stood at 6.98%, up from 5.38%, with the disclosed positions also encompassing securities lending arrangements. Unlike Citigroup's combined figure, this one refers to voting rights alone.
Price action and the lithium backdrop
The stock closed yesterday at €0.8550, a gain of 11%. Pre-market today it is down 1.8%, putting the shares under selling pressure following the company and shareholder announcements. No confirmed link between the drilling result and the share-price move has been established.
In Chinese lithium trading, the benchmark lithium carbonate futures contract rose by more than 5% at one point on Tuesday. Media reports attributed the move to a public notice advancing the environmental review process for the Jianxiawo mine. Accompanying market commentary tempered the significance of the step: resumption of mining operations had not been approved, and the sharp rebound lacked clear fundamental support.
