Key Highlights

  • Fulcrum Lithium shares rose following new Alkali Flats drill results
  • The company reported thick lithium mineralisation across multiple holes
  • Several drill holes ended in mineralisation and remain open at depth
  • Over 32km² of lithium mineralisation has now been delineated
  • Geological modelling is progressing toward a maiden resource estimate

Fulcrum Lithium (ASX: FUL) shares moved higher on Monday after the company released additional drilling results from its Alkali Flats lithium project in Nevada, USA, highlighting what management described as the thickest and highest-grade lithium mineralisation identified at the project to date.

The stock was trading at AUD 0.10 on 25 May 2026, up 7.14% for the session, as investors reacted to the latest Phase 3 drilling update and the company’s advancing resource modelling work.

According to Fulcrum, the final batch of assay results from the Phase 3 campaign confirmed broad zones of lithium mineralisation across the project, with several holes intersecting more than 100 metres of continuous mineralisation.

Management stated that the latest drilling outcomes continue strengthening confidence in the scale and continuity of the Alkali Flats deposit ahead of the company’s maiden Mineral Resource Estimate.

Thick Lithium Intercepts Extend Across Alkali Flats

The company reported that lithium mineralisation exceeding 300ppm lithium was intersected in 18 of the 20 holes included within the latest assay batch.

Several holes returned broad continuous mineralised intervals, including multiple intersections extending beyond 70 metres in thickness.

Among the standout results, hole AF3-E13 returned nearly 148 metres of lithium mineralisation and remained open at depth, while additional holes including AF3-E12, AF3-E19 and AF3-E23 also ended in mineralisation.

Fulcrum noted that assays from some intervals exceeded 1,100ppm lithium, while geological interpretation continues indicating extensive lateral continuity across the deposit area.

Management stated that the mineralised zones now extend over more than 8 kilometres of strike length and remain open in three directions.

Maiden Resource Estimate Moves Closer

The completion of the Phase 3 drilling campaign marks a key stage in the company’s ongoing evaluation of the Alkali Flats Project.

Fulcrum confirmed that geological modelling and data integration work are progressing ahead of the planned maiden Mineral Resource Estimate.

The Phase 3 program included 34 reverse circulation holes and five diamond core holes, significantly increasing drill density across the project area and reducing spacing between drill holes within the core mineralised zone.

According to the company, the additional drilling data is expected to improve confidence levels within future resource modelling and estimation work.

The company also stated that assay comparisons between reverse circulation and diamond core drilling returned closely matched values, providing further quality control validation for the sampling program.

Nevada Lithium Project Continues Expanding

Fulcrum’s Alkali Flats Project is located in Esmeralda County, Nevada, near several established lithium projects and operations within the broader region.

The company stated that the project now contains more than 32 square kilometres of delineated lithium mineralisation following the latest drilling campaign.

Management also noted that the project remains open in multiple directions, supporting ongoing exploration potential beyond the current drill-defined areas.

The broader exploration program follows earlier Phase 2 drilling, geophysical surveying and metallurgical work completed at the project.

About the Company

Fulcrum Lithium (ASX: FUL) is an Australian exploration company focused on lithium projects in North America. The company’s flagship Alkali Flats Project in Nevada is being advanced through drilling, geological modelling and resource definition activities targeting sediment-hosted lithium mineralisation.

Industry Trends and Market Context

Lithium markets continue attracting global attention due to Demand linked to electric vehicles, battery Manufacturing and energy storage technologies. Exploration activity across North America has remained active as companies seek to develop domestic lithium Supply chains and reduce dependence on overseas production sources.

Nevada remains an important Jurisdiction for lithium exploration given its established Mining infrastructure and growing strategic relevance within the United States battery materials sector.

However, lithium markets remain sensitive to Commodity price fluctuations, changing battery demand forecasts and broader macroeconomic conditions affecting electric vehicle adoption and Capital Investment across the sector.

Bullish Perspective

Supporters of Fulcrum Lithium may view the latest drilling results as further evidence of a potentially large-scale lithium system with broad mineralised continuity and expanding resource potential.

Investors may also focus on the approaching maiden Mineral Resource Estimate and the project’s location within a recognised lithium region in Nevada.

Bearish Perspective

More cautious investors may note that Alkali Flats remains at the exploration and resource-definition stage, with further technical studies and economic assessments still required.

Lithium price Volatility, future funding requirements and development risks may also affect long-term project advancement and market sentiment.

Investment Risks and Challenges

Fulcrum Lithium faces exploration and development risks associated with early-stage lithium projects, including geological uncertainty, permitting requirements and future financing needs.

There is no certainty that current exploration results will support economically viable mining operations. Commodity price movements and changing battery market conditions may also influence future project Economics.

Operational, technical and regulatory risks associated with advancing resource projects in the United States may additionally affect project timelines.
