Earth’s Energy has completed its exit from its geothermal joint venture, but has yet to identify a replacement asset capable of supporting a return to the ASX board. The company ended September with A$1.613 million in cash and its securities still suspended.

Vulcan Energy’s first matrix reinjection well delivered an estimated 64 standard litres per second, above the 40-litre assumption underpinning Lionheart’s development plan. The technical progress came alongside €98.0 million of quarterly investing outflows and a cash balance of €129.4 million ahead of expected project debt drawdown in Q1 2027.

EAU Lithium has deepened its technical relationship with Vulcan Energy Resources while the licensed VULSORB technology moves into commercial-scale manufacturing in Germany. The company ended September with A$2.621 million in cash, but its Bolivia strategy remains subject to negotiations and approvals.

Altamin has completed the technical work underpinning its Lazio Scoping Study, but pushed the release to the end of Q1 2027 while reporting A$1.56 million in cash and a 1.41-quarter funding estimate.

Foresta has secured acceptance of a Japanese patent for its rosin and terpene extraction technology while moving the Kawerau pine chemicals project through front-end design.

Altamin has completed the core technical work for its Lazio geothermal brine Scoping Study, but auditors have flagged material uncertainty over the company’s ability to continue as a going concern.

Contact Energy’s August operating report shows mass-market electricity and gas sales rising to 550GWh, while unit generation costs fell sharply to $40.90/MWh. Strong hydro storage and higher forward prices add support, although contracted wholesale sales remained broadly flat.
