Kingsland Minerals has extended high-grade lithium soil anomalies at its Lake Johnston project in WA, hinting at a significant hard rock lithium source and preparing for maiden drilling.
- High-grade lithium anomalies expanded beyond 200 ppm Li₂O
- Extensive soil sampling covers 890 sq km of project area
- Maiden drilling program planned to target hard rock lithium
- Project lies near known lithium deposits and greenstone belts
- Historical drilling intersected pegmatites but lacked lithium assays
Extended Lithium Anomalies Signal Hard Rock Potential
Kingsland Minerals (ASX:KNG) has significantly expanded the footprint of high-grade lithium soil anomalies at its Lake Johnston Lithium Project in Western Australia. The latest soil sampling campaign has identified multiple zones with lithium oxide (Li₂O) concentrations exceeding 200 ppm, extending known anomalies and reinforcing the prospect of a nearby hard rock lithium source.
The company is now gearing up for its maiden drilling program aimed at targeting lithium mineralisation in fresh rock, a crucial next step to validate the surface geochemical signals. The project’s 890 square kilometre tenement package straddles the Lake Johnston Greenstone Belt, a geological setting known for hosting hard rock lithium and nickel deposits.
Strategic Location Near Established Lithium Deposits
Lake Johnston sits in a lithium-rich corridor, with major deposits such as Bald Hill, Dome North, and Mt Holland located nearby. These deposits cluster around the Binneringie Dyke, a significant Proterozoic geological feature that also traverses Kingsland’s tenements, providing a compelling exploration target.
Historical nickel-focused drilling in the area, including by previous explorers and Western Areas, intersected pegmatitic dykes and greenstone lithologies; key indicators of potential lithium mineralisation. However, lithium assays were not conducted during those earlier programs, leaving a gap that Kingsland’s current exploration seeks to fill.
Comprehensive Soil Sampling and Analytical Techniques
The recent soil sampling program involved over 3,000 samples collected on a 1,000m by 200m grid, with a denser 500m by 200m grid in areas showing the highest lithium anomalies. Samples were taken from shallow depths (5-30cm) and analysed using the Ultrafine method by Labwest in Perth, which isolates the <2 micron fraction for sensitive multi-element ICP-MS and ICP-OES assays.
These assays included lithium and a suite of 65 other elements, allowing Kingsland to map geochemical signatures in detail. The lithium anomalies correlate with magnetic highs from Geological Survey of Western Australia data, suggesting structural or lithological controls on mineralisation that will guide future drilling.
Next Steps: Drilling and Geophysical Surveys
Encouraged by the strong geochemical results, Kingsland is planning a maiden drilling campaign to test for hard rock lithium mineralisation beneath the soil anomalies. The company is also considering geophysical surveys to better understand the fresh rock geology and refine drill targets.
Managing Director Richard Maddocks highlighted the significance of the findings, noting that the soil anomalies provide "more evidence of the potential presence of lithium-bearing lithologies" within the tenement package. He pointed to recent successful lithium drilling by other companies in the wider Lake Johnston area following similar soil anomaly footprints, underscoring the prospectivity of Kingsland’s ground.
While the Lake Johnston project remains at an early stage, these developments mark a meaningful step forward in unlocking its lithium potential. Kingsland’s broader portfolio also includes the Leliyn Graphite Project, where recent metallurgical breakthroughs and capital raises have advanced the company’s battery materials ambitions, as detailed in their recent maiden gallium resource plans and high-grade graphite assays.
Bottom Line?
Kingsland’s expanded lithium anomalies at Lake Johnston set the stage for drilling that will be critical to confirming hard rock lithium mineralisation and advancing project valuation.
Questions in the middle?
- Will the upcoming drilling confirm economically viable hard rock lithium deposits?
- How will geophysical survey results refine Kingsland’s exploration targeting?
- What impact could broader lithium market dynamics have on the project’s development?
