Sentiment and the balance of points

Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.

Lithium Harvest (SPGX) signed a letter of intent with a geothermal development partner for a proposed integrated power and lithium joint venture.

The planned Alberta, Canada facility targets approximately 28,500 tonnes of lithium carbonate and 0.67 TWh of renewable electricity annually at full nameplate capacity. Development is planned in two phases, with first power generation and lithium carbonate production targeted for 2028. The design uses geothermal heat for power and geothermal brine for lithium extraction and refining.

The partners plan to finalize joint venture arrangements, validate the resource and lithium process, advance engineering and permitting, and secure construction financing. Production remains subject to validation, approvals, financing, construction and commissioning. Lithium Harvest plans to update its financial model and investment materials for the proposed development.

How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

Project targets 0.67 TWh of electricity and 28,500 tonnes of lithium carbonate annually at full nameplate capacity, with first production targeted for 2028.

AALBORG, Denmark, Oct. 13, 2026 /PRNewswire/ -- Lithium Harvest Holding A/S ("Lithium Harvest") has signed a letter of intent (LOI) with a geothermal development partner to form a joint venture to develop an integrated geothermal power and lithium production facility in Alberta, Canada.

At full nameplate capacity, the planned facility targets approximately:

  • 28,500 tonnes of lithium carbonate annually
  • 0.67 TWh of renewable electricity annually

The planned project will generate revenue from renewable baseload electricity and lithium carbonate produced from the same geothermal resource, expanding Lithium Harvest's North American development portfolio.

Development is planned in two phases, with full nameplate capacity reached through phased construction and production ramp-up.

"This agreement advances our ambition to produce some of the world's cleanest energy and lithium at low cost," said Sune Mathiesen, Chairman of Lithium Harvest. "The rapid buildout of data centers and the energy transition in general require large amounts of reliable power as well as lithium for EV's and battery storage. Once completed, this will be one of the largest facilities of its kind in the world."

"Our focus now is on the resource validation, engineering and financing needed to turn the project's potential into commercial production."

Integrated Geothermal Power and Lithium Production

The geothermal development partner will contribute its geothermal development capabilities, while Lithium Harvest will contribute its integrated brine-to-battery-grade lithium platform, combining water treatment, proprietary Direct Lithium Extraction (DLE) technology, and refining designed to produce battery-grade lithium carbonate. The integrated design will use geothermal heat for power generation and geothermal brine as the feedstock for lithium extraction and refining.

The project is designed to serve two markets: responsible and reliable electricity and battery materials. Combining the production streams is intended to improve resource utilization, while phased development will allow capital to be deployed progressively. The project also has the potential to strengthen domestic lithium supply and dramatically diversify the North American lithium supply chain.

Based on current project estimates, operation at full nameplate capacity could avoid up to 933,000 tonnes of CO₂ emissions annually. Actual reductions will depend on the final design, operating performance, electricity displacement, and reference scenarios used for comparison.

Next Steps

The partners plan to advance the proposed joint venture through the following workstreams:

  • Finalize joint venture arrangements and the integrated development plan.
  • Confirm geothermal resource and lithium process performance through evaluation and technical validation.
  • Advance engineering, permitting and commercial arrangements.
  • Secure the project financing required for construction.

Lithium Harvest plans to update its financial model, investor presentation and investment memorandum to reflect the proposed development, including production assumptions, phased capital requirements and project economics. Progress toward production remains subject to successful completion of the required validation, approvals, financing, construction, and commissioning.
