Vulcan Energy Resources Limited (ASX:VUL) is developing an integrated lithium extraction and geothermal renewable energy Business in the Upper Rhine Valley of Germany. Its operations focus on recovering lithium from geothermal brine and converting it into battery-grade lithium chemicals, while generating renewable electricity and heat. The company's H1 2026 performance reflected increased development expenditure, financial close for the Lionheart project and ongoing construction activities ahead of planned commercial lithium production.

Lionheart Project Achieves Financial Close

Vulcan announced on 28 May 2026 that its approximately €2.2 billion financing package for the first phase of the Lionheart project had reached financial close.

The package combines Equity and Debt Financing arrangements involving government-supported institutions, commercial lenders and strategic industrial partners.

Financial close followed the company's financing announcement and final Investment decision in December 2025.

The arrangements provide access to project funding, subject to ongoing drawdown conditions and construction requirements.

Funding is expected to be drawn progressively in line with the development schedule and Capital Expenditure requirements.

The milestone allows Vulcan to continue implementing its construction programme, although project delivery remains dependent on engineering, procurement, operating approvals and cost management.

Lionheart Targets Battery-Grade Lithium Production

The Lionheart project is located within the Upper Rhine Valley Brine Field, extending across Germany and France.

The development is designed to extract lithium from naturally heated geothermal brine using Vulcan's proprietary VULSORB technology.

The first phase targets annual production capacity of approximately 24,000 tonnes of lithium hydroxide monohydrate.

Management estimates this quantity could support production of approximately 500,000 electric vehicle batteries each year, depending on battery chemistry and capacity assumptions.

The project also targets annual generation of approximately 275 gigawatt-hours of renewable electricity and 560 gigawatt-hours of renewable heat.

Its estimated operating life is approximately 30 years.

These figures represent project targets rather than achieved commercial production.

Construction Activities Progress During June Quarter

Vulcan reported construction progress across several Lionheart project components during the quarter ended 30 June 2026.

Major construction activities commenced at the lithium chemicals plant in Frankfurt, following a groundbreaking ceremony.

Early site preparation and civil works progressed alongside engineering and procurement activities.

At the geothermal and lithium extraction facilities, the company continued bulk earthworks and preparation of infrastructure required for future operations.

Civil construction of the geothermal power plant subsequently commenced in July 2026.

The company also progressed procurement and engineering activities for the interconnected pipeline and power infrastructure.

These facilities are intended to connect production wells, geothermal plants and lithium processing operations.

Drilling Programme Supports Project Development

Vulcan completed drilling of its sixth production and reinjection well during the June quarter.

The company reported that the well was delivered on schedule and below budget.

Measured lithium concentration, reservoir temperatures and production characteristics were within the expected ranges for the project.

The seventh well commenced drilling before the end of June 2026.

Further production and reinjection wells are planned as part of the wider Lionheart development programme.

Vulcan also continued preparing additional well sites and infrastructure required for the planned operating capacity.

Future drilling results will remain relevant to reservoir performance, production planning and the development schedule.

H1 2026 Financial Results Reflect Development Expenditure

Vulcan reported revenue from continuing operations of approximately €2.3 million for the six months ended 30 June 2026, compared with €4.1 million in H1 2025.

The company recorded a net loss after tax of €51.8 million, compared with €30.7 million in the corresponding period.

The increased loss reflected development-stage operating expenses, financing costs and foreign exchange movements.

Vulcan also reported an EBITDA loss of approximately €33.7 million, compared with €25.2 million in H1 2025.

At 30 June 2026, cash and cash equivalents stood at €193.9 million.

The company also held approximately €80.0 million in term deposits, bringing cash and short-term deposits to approximately €273.9 million.

The financial results reflect the company's current development phase, during which construction and operating expenditure precede commercial lithium revenue.

Capital Expenditure and Funding Requirements

Vulcan reported approximately €92.0 million in development expenditure during the June quarter.

Investment was primarily directed towards Lionheart construction, drilling and associated infrastructure.

The company continued implementing project financing arrangements following financial close.

In July 2026, Vulcan confirmed receipt of its initial strategic equity funding instalment after meeting the relevant drawdown conditions.

The company expects further financing to be accessed progressively as construction advances.

However, funding availability remains linked to compliance with financing conditions and the delivery of project milestones.

Any changes in construction expenses or scheduling may influence capital requirements.

Lithium and Renewable Energy Business Model

Vulcan's proposed operating model combines lithium chemical production with Geothermal Energy generation.

Geothermal brine contains lithium that can be extracted before the processed brine is reinjected into the reservoir.

The recovered lithium is intended for conversion into battery-grade lithium hydroxide.

Renewable electricity and heat generated through the process are expected to support operations and Supply local consumers.

This combination creates potential revenue streams from lithium products and geothermal energy.

However, future commercial performance will depend on production efficiency, customer agreements, Commodity prices and operating costs.

The project remains in development, and its targeted production capacity has not yet been achieved.

Development Outlook and Key Risks

Vulcan continued progressing the Lionheart construction programme following financial close.

The project involves further drilling, plant construction, procurement and commissioning activities before commercial lithium production can commence.

The company is targeting its initial production phase in 2028, subject to project completion and commissioning requirements.

Management also continues evaluating potential future developments in the Upper Rhine Valley.

However, additional projects remain subject to technical studies, funding arrangements and investment decisions.

Construction costs: Higher equipment, labour and infrastructure expenses could increase development requirements.

Technology execution: Commercial-scale lithium extraction and processing performance remains subject to commissioning and operational verification.

Lithium pricing: Changes in global battery material prices may affect future project revenue.

Funding conditions: Future financing drawdowns require compliance with contractual and project-related obligations.

Development timing: Delays in construction, drilling or commissioning could affect the planned production schedule.

The Bottom Line

Vulcan Energy Resources' achievement of financial close represents a financing milestone for the Lionheart lithium and geothermal development.

Construction, drilling and infrastructure activities progressed during H1 2026, while financial results reflected continued development expenditure and the absence of commercial-scale lithium revenue.

Future performance will depend on the delivery of construction milestones, financing arrangements, commissioning outcomes and eventual lithium production and sales.
