Kingsland Minerals Expands High-Grade Lithium Soil Anomalies Across Lake Johnston

Kingsland Minerals Extends High-Grade Lithium Anomalies Across 890 sq km at Lake Johnston, Western Australia

Kingsland Minerals (ASX: KNG) has announced a significant expansion of lithium soil anomalies at its Lake Johnston project in Western Australia, with a major sampling campaign confirming high-grade surface lithium mineralisation across most of the company's 890 square kilometre tenement package. The Kingsland Minerals Lake Johnston lithium soil anomalies in Western Australia strengthen the case for a nearby hard rock lithium source and have triggered planning for a maiden drilling programme.

The announcement follows an extensive soil geochemistry programme that has identified +200 ppm Li₂O anomalies extending from previous programmes, with multiple sample locations across both northern and southern areas recording results above this high-grade threshold.

Extensive High-Grade Results Define Large-Scale System

The latest programme, combined with earlier sampling completed in 2024, brings the total number of soil samples collected at Lake Johnston to 3,099. Samples were taken on a grid pattern of 200m east-west and either 500m or 1,000m north-south across the project area.

Key findings include:

• +200 ppm Li₂O anomalies extended from previous programmes, with multiple sample locations across both northern and southern project areas
• Extensive +100 ppm Li₂O anomalies identified across the broader project area
• Samples collected from 5–30cm below surface, processed to -80 mesh fraction, and analysed using the Ultrafine method across a 65-element suite

Selected High-Grade Sample Results

The highest single result of 294.9 ppm Li₂O was recorded at sample KNG0242 in the northern portion of the project. Furthermore, these results demonstrate that elevated lithium values occur consistently across broad portions of the project area, rather than as isolated occurrences.

Management Commentary: Targeting a Hard Rock Source

"These are very promising results because they provide more evidence of the potential presence of lithium-bearing lithologies within our Lake Johnston tenement package. Historical drilling targeting nickel has intersected pegmatitic textures and greenstone lithologies in our tenements and we have confirmation of lithium mineralisation in the wider Lake Johnston area with recent successful drilling by other companies following up similar soil anomalism."

— Richard Maddocks, Managing Director, Kingsland Minerals

Surface soil sampling programmes are commonly used in early-stage exploration to identify anomalous zones and prioritise ground for follow-up drilling. The significance of lithium appearing consistently at elevated grades across such a wide area strongly implies an underlying source of lithium-bearing geology.

Historical drilling conducted at Lake Johnston in 2008 by previous explorers targeting nickel intersected pegmatite dykes within the tenements. However, lithium and associated elements were not assayed at the time, meaning the lithium potential of those intersections was never evaluated.

Understanding Soil Geochemical Anomalies in Lithium Exploration

For investors less familiar with exploration methodology, a soil geochemical anomaly refers to areas where chemical concentrations of a target element in surface soils are significantly elevated above regional background levels.

Why Does This Matter for Lithium?

In lithium exploration, soil anomalies are particularly significant for several reasons:

1. Source indication: Lithium-bearing pegmatite bodies weather over geological time and release lithium into surrounding soils
2. Depth targeting: Elevated lithium in soils indicates lithium-bearing rock is likely present beneath the surface
3. Grade significance: Anomalies at +100 ppm Li₂O and especially +200 ppm Li₂O are considered significant thresholds

Technical Methodology

The Lake Johnston programme used the Ultrafine analytical method, which targets the very fine clay fraction of soil samples. This technique is particularly sensitive for detecting lithium anomalies in weathered terrains and is considered appropriate for this style of exploration.

In addition, the results show correlation between lithium anomaly distribution and underlying structural features visible in Total Magnetic Intensity survey data from the Geological Survey of Western Australia. This structural alignment adds confidence that surface anomalies reflect genuine geological contacts at depth.

Key Technical Terms

• Li₂O (Lithium Oxide): Standard unit for expressing lithium content in mineral exploration
• Pegmatite: Coarse-grained igneous rock that forms the primary host for hard rock lithium mineralisation
• TMI (Total Magnetic Intensity): Geophysical measurement used to map subsurface geological structures

Strategic Location Within a Proven Lithium Province

The Kingsland Minerals Lake Johnston lithium soil anomalies in Western Australia sit within the Southern Cross Province of the Archaean Yilgarn Craton, positioned between the Lake Johnston Greenstone Belt and the Forrestania Greenstone Belt. A major Proterozoic structure known as the Binneringie Dyke runs through the project area, passing in proximity to several established lithium deposits in the region.

Regional Context: Nearby Lithium Resources

These are established, JORC-compliant resources demonstrating the mineralised nature of the geological terrain. It is important to note that Kingsland does not currently hold a mineral resource at Lake Johnston; the project remains at early exploration stage.

Next Steps: Transition to Drilling

The results will now inform targeted follow-up programmes. Kingsland's planned next steps include:

Immediate Priorities

1. Maiden drilling programme — planning underway to drill fresh rock beneath surface anomalies
2. Geophysical surveys — potential airborne or ground-based surveys to assess fresh rock geology
3. Additional soil sampling — infill sampling on tighter grids in highest anomalism areas
4. Structural interpretation — analysing relationships between lithium contours and magnetic imagery

The maiden drilling programme represents the next material catalyst for Lake Johnston. Drilling into fresh rock will allow determination of whether surface anomalies source from nearby pegmatite or other lithium-bearing lithologies, and establish grade and thickness of any mineralisation at depth.

Investment Context: A Multi-Commodity Portfolio

Kingsland Minerals maintains a portfolio of energy mineral assets beyond the Lake Johnston project.

Core Assets

• Leliyn Graphite Project (NT): Inferred Mineral Resource of 194.6 Mt at 7.3% TGC, containing 14.2 Mt of graphite, supported by a scoping study indicating potential for profitable production
• Cleo Uranium Deposit (NT): Inferred Mineral Resource containing 5.2 million pounds of U₃O₈

Lake Johnston Value Drivers

The lithium results add a third commodity dimension to this energy minerals portfolio. Key differentiators include:

• Scale of anomalism: Continuous, project-wide sampling across 890 sq km confirms lithium anomalies extend broadly
• Historical intersections: Prior nickel drilling intersected pegmatite dykes but did not assay for lithium, providing ready-made targets
• Regional context: Proximity to the Binneringie Dyke and demonstrated lithium productivity nearby
• Structural correlation: Alignment of soil contours with magnetic features adds confidence to target generation

The company now approaches a potential inflection point. Having completed comprehensive surface geochemical surveying across the majority of its tenement package, the transition to subsurface testing with drilling could materially change the investment case if lithium-bearing pegmatites are intersected.

Key Investment Considerations: Kingsland Minerals has completed one of the most comprehensive lithium soil sampling programmes at Lake Johnston to date, returning widespread high-grade anomalies including results exceeding 260 ppm Li₂O. With a maiden drilling programme being planned across a project located within a proven lithium-producing geological belt, the upcoming transition from surface exploration to testing the source of the Kingsland Minerals Lake Johnston lithium soil anomalies in Western Australia at depth represents a critical development phase for investors to monitor closely.
