Charger Metals Regains Full Control of High-Grade Lake Johnston Lithium Project
Charger Metals NL (ASX: CHR) has terminated its farm-in agreement with Rio Tinto Exploration, retaining 100% ownership of the Lake Johnston Lithium and Gold Project. This strategic decision comes after Rio Tinto invested $6.4 million across exploration programmes, equity subscription, and cash payments over two years.
The Charger Metals Lake Johnston project now houses a Maiden Inferred Resource of 8.2Mt @ 1.0% Li2O at Medcalf, plus an Exploration Target of 3-5Mt @ 1.0-1.4% Li2O at Medcalf West. Furthermore, with four lithium processing plants within trucking distance and upcoming drilling campaigns planned for January 2025, Charger is well-positioned to capitalise on the project's substantial potential.

Rio Tinto Investment Delivers Significant Value Before Exit
Over the past two years, Rio Tinto Exploration has substantially de-risked the Charger Metals Lake Johnston project through strategic investment. The total commitment reached $6.4 million, comprising multiple components that have advanced project development.
The investment breakdown includes $4.2 million in funded exploration programmes, $1.2 million equity subscription in Charger shares, and $1.0 million in direct cash payments. Additionally, Rio Tinto would have needed to invest a further $5.8 million in exploration plus $1.0 million in cash payments to earn its initial 51% stake.
The termination agreement allows both parties to pursue their strategic objectives independently. For instance, this arrangement provides Charger with complete control over project direction whilst enabling Rio Tinto to focus resources on larger-scale opportunities.
Managing Director's Perspective
Managing Director Bryan Dixon commented: "The Charger team are pleased to have retained a 100% interest in the Lake Johnston Gold and Lithium Project and would like to thank Rio Tinto Exploration for its contribution in advancing the exploration over the last 2 years."
He further noted: "To date we have not identified a Rio Tinto size project however the Charger team see significant potential to grow the scale of the maiden Medcalf Spodumene Resource."
Strategic Asset Portfolio Positioned for Growth
Lake Johnston Project Assets
| Asset | Resource/Target | Grade | Status |
|---|---|---|---|
| Medcalf | 8.2Mt Maiden Inferred Resource | 1.0% Li2O | JORC-compliant resource |
| Medcalf West | 3-5Mt Exploration Target | 1.0-1.4% Li2O | Conceptual target |
| Regional Gold Rights | 100% ownership | Various | Medcalf & Mt Gordon tenements |
The project benefits from exceptional infrastructure proximity, with four lithium concentration plants within trucking distance. This logistics advantage significantly reduces potential development costs and timeline to production compared to remote lithium projects.
Moreover, the systematic exploration approach targets both near-surface, outcropping mineralisation. These characteristics are ideal for potential future mining scenarios given the reduced strip ratios and development costs associated with surface-accessible orebodies.
Recent Drilling Results Expand Exploration Pipeline
Charger's October 2024 RC drilling programme at the Whitten prospect delivered encouraging results. The standout intersection came from drill hole CLDRC005, which intersected 2m @ 1.03% Li2O from 14-16m depth.
The recent drilling campaign achieved significant progress with a total programme of 3,422m across Mt Day and Mt Gordon prospects. However, assays are pending for 3,012m of recent drilling, with results expected to provide additional insights into regional potential.
The programme successfully identified LCT pegmatite in multiple holes at Whitten, confirming lepidolite-dominant mineralisation both at surface and downhole. The gentle 20° northward dip of the Whitten pegmatite suggests good continuity potential and favourable mining geometry.
Understanding LCT Pegmatites
LCT (Lithium-Caesium-Tantalum) pegmatites represent some of the world's most valuable hard-rock lithium sources. These coarse-grained igneous rocks form during the final stages of granite crystallisation, concentrating rare metals including lithium, caesium, and tantalum.
For investors, LCT pegmatites are significant because they typically contain spodumene and lepidolite. These are the primary lithium-bearing minerals that can be economically processed into battery-grade lithium compounds for the growing electric vehicle market.
Upcoming Catalysts and Exploration Timeline
The Charger Metals Lake Johnston project has positioned itself for an active 2025 exploration programme with several key catalysts approaching. The company has received drill approvals for up to 41 holes for the upcoming campaign.
Immediate Priorities for Q1 2025
The January 2025 diamond and RC drilling programme will commence at Medcalf and Medcalf West prospects. In addition, the company awaits pending assay results from 3,012m of recently completed drilling.
The strategic focus encompasses resource extension drilling at the established Medcalf deposit. Furthermore, the programme includes maiden resource definition at the high-potential Medcalf West prospect and regional exploration across the broader Mt Day LCT pegmatite field.
Investment Thesis: Premium Location Meets Proven Resources
Competitive Positioning
| Advantage | Benefit | Investment Impact |
|---|---|---|
| Infrastructure Access | 4 processing plants within trucking distance | Reduced development capex |
| High-Grade Resources | 1.0%+ Li2O grades | Premium product positioning |
| Surface Mineralisation | Outcropping pegmatites | Lower mining costs |
| 100% Ownership | No joint venture complications | Full economic exposure |
Regional Context
The Charger Metals Lake Johnston project sits 70km east of the major Earl Grey (Mt Holland) Lithium Project, which commenced production in March 2024. Mt Holland represents one of Australia's largest hard-rock lithium projects with Ore Reserves of 189Mt @ 1.5% Li2O.
This positioning provides a proven commercial benchmark for the region's lithium potential. Charger's strategic location within this established lithium corridor positions the company to benefit from existing infrastructure, established supply chains, and proven geological prospectivity.
Recent Drilling Programme Results
Whitten Lithium Prospect Performance
| Hole ID | Depth From (m) | Depth To (m) | Interval (m) | Li2O % | Li ppm | Cs ppm |
|---|---|---|---|---|---|---|
| CLDRC005 | 14 | 16 | 2 | 1.03 | 4,796 | 1,091 |
| CLDRC006 | – | – | – | NSI | NSI | NSI |
| CLDRC007 | – | – | – | NSI | NSI | NSI |
*NSI = No Significant Intersection
The interpretation indicates that the Whitten LCT pegmatite has lepidolite dominant mineralisation at surface and in drilling. The gentle dip of approximately 20° to the north suggests favourable conditions for potential future extraction scenarios.

Why Should Investors Follow Charger Metals?
The termination of the Rio Tinto agreement marks a pivotal moment for Charger Metals. The company now has full strategic control over a high-quality lithium project that has been significantly de-risked through $6.4 million of third-party investment.
With immediate drilling programmes planned and 100% economic exposure to any discoveries, Charger offers pure-play exposure to Western Australia's emerging lithium corridor. However, investors should monitor several key developments throughout 2025.
Key Tracking Points for 2025
January drilling results from the 41-hole permitted programme represent the immediate catalyst. Subsequently, resource upgrade potential at Medcalf through extension drilling could significantly impact valuations.
Maiden resource definition at the 3-5Mt Medcalf West target offers substantial upside potential. Additionally, regional exploration success across the broader Mt Day pegmatite field could unlock further value.
Competitive Advantages
The project benefits from premium infrastructure access with four processing plants nearby. Moreover, high-grade surface mineralisation reduces development complexity whilst the established resource base offers clear expansion potential.
The proven geological setting within Australia's premier lithium corridor provides additional confidence. Furthermore, the 100% ownership structure eliminates joint venture complications and provides full economic exposure to project success.
The Charger Metals Lake Johnston project has positioned itself as a focused lithium explorer with proven high-grade resources in Western Australia's established lithium corridor. With $6.4 million of Rio Tinto-funded exploration providing significant de-risking and immediate drilling catalysts approaching, investors should monitor CHR closely as it advances toward potential resource expansion and development scenarios.
