Redstone Resources Limited (ASX: RDS) (Redstone or the Company) is pleased to announce the results of recently completed prospectivity analysis, which has identified a significant number of high priority Lithium‐Caesium‐Tantalum (LCT) pegmatite target areas on the Radisson East Lithium Project and Sakami Lithium Project (collectively the Projects) in James Bay, Québec, Canada.
HIGHLIGHTS
- Prospectivity analysis completed by Mercator Geological Services has generated:
- eighteen (18) Lithium‐Caesium‐Tantalum (LCT) pegmatite target areas across the Sakami Lithium Project; and
- six (6) LCT pegmatite target locations across the Radisson East Lithium Project.
- Targets are identified in areas where favourable lithology, mineralisation, structure and geochemistry for LCT pegmatites occur together.
- The highest priority targets on the Sakami Lithium Project (S01 through S04) occur towards the boundary between the La Grande and Opinaca sub‐province, in an area where amphibolite is truncated by faulting; and are associated with low level geochemical anomalism that is found with LCT pegmatites (see Figure 2).
- The highest priority targets on the Radisson East Project (RE01 and RE02), occur within an amphibolite and an area of low‐level geochemical anomalism found with LCT pegmatites (see Figure 3).
- Radisson East and Sakami Projects have a combined area of 90km2 and cover more than 40 km of the Yasinski Group greenstone belt. Greenstone belts in the James Bay area host a number of pegmatite occurrences including Q2 Metals Corp.’s Mia Lithium Deposit within the Yasinski greenstone belt.
- Planning is now underway to follow up the generated targets at both the Sakami and Radisson East Projects.
- An initial field programme will include field mapping, outcrop sampling and geochemical sampling over the most prospective target areas.
Redstone retained Mercator Geological Services Limited (Mercator) to complete their proprietary prospectivity analysis method on Sakami and Radisson East Projects, identifying eighteen (18) target areas and six (6) target areas respectively on the Projects.
The Sakami Lithium Project (68 km2) consists of three claim blocks within the La Grande sub‐province situated approximately 14 km north of the boundary between the La Grande and Opinaca sub‐ provinces, in a similar geological setting as the Corvette (Patriot Battery Metals), Cancet (Winsome Resources Ltd.) and Adina Lithium Deposits (Winsome Resources Ltd.) lithium deposits, which all occur 10 to 20 km north of the boundary (Figure 1).
The Radisson East Lithium Project (22 km2) consists of two claim blocks, both within the La Grande sub‐province and 55 kilometres to the northeast of Q2 Metals Corp.’s Mia Lithium project (Figure 1).

The primary purpose of this prospectivity analysis was to identify priority lithium targets within the Projects to guide further exploration. The prospectivity model used was designed on the LCT (lithium‐ cesium‐tantalum) pegmatite deposit model of Černy & Ercit (2005)1, and review of data from the known lithium deposits in the area. The final version of the prospectivity map consisted of 79 input layers of data sourced from the Government of Québec’s Geomining Information System (SIGÉOM) that were used to calculate the prospectivity weightings. The model was designed to highlight the best lithium targets where favourable structure, lithology, mineralisation, and LCT pegmatites geochemistry occur.
SAKAMI LITHIUM PROJECT
The prospectivity analysis has generated eighteen (18) target areas that are prospective for LCT pegmatites across the Sakami Lithium Project, (Figure 2).
The two easternmost claim blocks follow a north‐south trend of elevated prospectivity scores, and the northwestern‐most claim block is highlighted by an elevated prospectivity score along its northern boundary (Figure 2). The north‐south trend of prospectivity appears to be associated with amphibolite and paragneiss units along north‐northeast‐trending faults.

The highest priority targets on the Sakami Lithium Project are targets S01 through S04 to the south end of the Project towards the La Grande‐Opinaca sub‐province boundary. These high priority targets occur in an area where a north to south trending amphibolite unit is truncated by east to west faulting and an increase in low level geochemical anomalism that is associated with LCT pegmatites occurs in the direction of the La Grande‐Opinaca regional geological boundary.
Targets S08 and S09 (Figure 2), lying towards the La Grande‐Minto geological boundary in the northeastern most claim block, appears to be associated with favourable lithology and structure that is commonly associated with LCT pegmatites in the James Bay area.

Investor Insight
Redstone Resources is strategically positioned to benefit from rising global demand for battery metals, with 100 percent ownership of its copper-focused West Musgrave project in WA and a lithium acquisition in Canada.
Overview
Australia, a top global producer of key minerals like copper, nickel, lithium, and gold, supports growing demand through its stable, mining-friendly jurisdictions. The underexplored Musgrave Province hosts significant deposits of critical metals including nickel, PGEs, copper, and rare earths.
Redstone Resources (ASX:RDS) is exploring its 100 percent-owned West Musgrave Project in Western Australia, home to the Tollu Copper deposit. The project lies near major discoveries such as BHP’s Nebo-Babel and Succoth deposits, and Nico Resources’ Wingellina project.
With additional tenement applications in the region and a leadership team experienced in geology, exploration, and business development, Redstone is well-positioned to advance its battery and base metals strategy.
The unique Musgrave terrain has attracted major players like BHP, which is advancing construction of its Nebo-Babel nickel-copper-PGE mine after securing final approvals. The deposit hosts 390 Mt at 0.30 percent nickel and 0.33 percent copper, containing 1.2 Mt of nickel and 1.3 Mt of copper (2012 JORC). Alongside Nico Resources’ Wingellina nickel-cobalt deposit, these discoveries highlight the region’s potential as a major base metals hub.
Redstone’s West Musgrave Project lies between these key deposits—just 60 km east of Nebo-Babel and 50 km west-southwest of Wingellina. The project remains underexplored but is highly prospective, with geology suited to magmatic nickel-copper sulphides, VHMS, and large hydrothermal systems.
Location of Redstone's West Musgrave Project and the Tollu Cu Deposit relative to the world class Nebo-Babel Cu-Ni-Co Deposit and other deposits and prospects in the area.
Redstone Resources’ 100 percent-owned Tollu copper deposit, part of its West Musgrave Project, hosts a JORC-compliant resource of 3.8 Mt at 1 percent copper for 38,000 tonnes of contained copper (0.2 percent cut-off). A conceptual exploration target suggests potential for up to 627,000 tonnes of copper.
Expanding beyond Australia, Redstone is building a lithium portfolio in Canada through a 50/50 joint venture with Galan Lithium (ASX:GLN), acquiring 100 percent of the Camaro, Taiga, and Hellcat Projects in Quebec’s James Bay Lithium District. This region hosts key discoveries, including Patriot Metals’ (ASX:PMT,TSXV:PMET) Corvette Project and Winsome Resources’ ASX:WR1) Cancet Project. Notably, Patriot’s CV8 and CV13 pegmatites lie just 1.4 km from Taiga and 1.5 km from Camaro, respectively.
Redstone will manage the 5,187-hectare JV, backed by a seasoned team with deep expertise in exploration, operations, and corporate strategy.
Company Highlights
- Redstone Resources is an Australia-based mineral exploration company exploring highly prospective properties for copper and other base metals in the West Musgrave region of Western Australia.
- The West Musgrave region is home to major discoveries, including the world-class Nebo-Babel nickel-copper-PGE sulphide deposit and the Wingellina nickel-cobalt deposit, attracting significant interest from major miners.
- Redstone’s 100 percent-owned West Musgrave Project lies just 60 km west of BHP’s Nebo-Babel, highlighting the strong prospectivity of its tenure. The project hosts the Tollu Copper vein deposit, evidence of a large hydrothermal system, and is situated in a geological and structural setting highly favourable for magmatic nickel-copper sulphide, VHMS, and intrusive-related hydrothermal deposits

- The Redstone and Galan Lithium joint venture project acquisitions complement the company’s West Musgrave and its strategy to increase exposure to the growing global battery metals and explore for critical minerals in high demand.
- A strong management team leads the company with decades of experience in the resources sector.
Key Projects
The West Musgrave Project
The West Musgrave Project spans 213 sq. km. of highly prospective yet underexplored terrain. Redstone believe their West Musgrave Project, and the entire West Musgrave Region, has the appropriate setting required to host major Ni-Cu-PGE deposits, such as the Voiseys Bay deposit in Canada. The geological setting of the West Musgrave is comparable to the Nain-Churchill province boundary in Canada, which in Labrador, hosts the world-class Voisey’s Bay deposit.
Voisey’s Bay is considered a ‘giant’ Ni-Cu deposit; in one section alone it contained 31.7Mt of ore grading 2.83 percent nickel and 1.68 percent copper. Voisey’s Bay is also relatively unique in that it is one of a very few Ni-Cu-Co deposits that are hosted in mafic, not ultramafic rocks. Another is Nebo Babel, which is situated only 60km west of Redstone’s Tollu Cu Deposit.
Drilling 7.5 km northeast of the Tollu Copper Vein deposit has confirmed the presence of similar rocks to those that host Nebo Babel, and with low-grade Cu mineralisation, further enhancing the prospectivity of Redstone’s project.
Given the favourable geology, Redstone believe it is possible that the high grade vein hosted Cu of Tollu could potentially be a remobilisation from a much larger accumulation of sulphides nearby and hence remains a priority target area for world class deposits.
The Tollu Copper Vein Project
Tollu, part of the broader West Musgrave Project, features a large swarm of copper-rich hydrothermal veins across a 5 km² area, with surface mineralisation linked to a dilation system between two major shears. The deposit hosts a JORC 2012 resource of 3.8 Mt at 1 percent copper and 0.01 percent cobalt, containing 38,000 tonnes of copper and 535 tonnes of cobalt, with strong potential for expansion through further drilling.
Local Geology Map – Redstone’s West Musgrave Project
The Tollu Cu deposit represents a high-grade Cu accumulation from the surface to a depth of approximately 400m as evidenced by deep drilling intersections that consistently deliver strong results, particularly at the Chatsworth and Forio prospects. These results include:
Chatsworth Prospect
- TLC189: 25m at 1.46 percent copper from 61m, incl. 1m at 5.1 percent copper
- TLC192: 25m at 1.1 percent copper from 53m, incl. 7m at 2.64 percent copper
- TC80: 10m at 3.4 percent copper from 427m, incl. 5m at 5.3 percent copper
- TLC033: 5m at 2.21 percent copper from 100m
- TLC034: 15m at 1.39 percent copper from 136m, incl. 3m at 3.67 percent copper
Forio Prospect
At Forio, drilling confirmed further high-grade zones, including the highest copper grade recorded to date at Tollu—1m at 18.5 percent copper from 18m in TLC203. Additional results include:
- 8m at 4.1 percent copper from 13m, incl. 1m at 18.5 percent copper (TLC203)
- 4m at 1.2 percent copper from 45m (TLC203)
- 6m at 1.47 percent copper from 80m (TLC201)
- 34m at 1.07 percent copper from 15m, incl. 2m at 3.2 percent copper (TLC181)
Redstone and Galan 50/50 Joint Venture
James Bay Lithium Projects - Taiga, Camaro and Hellcat
Redstone Resources and Galan Lithium formed a 50/50 JV to acquire the James Bay Lithium Projects in Quebec, comprising the highly prospective Taiga, Camaro, and Hellcat Projects. Covering 3,850 hectares, the projects lie adjacent to Patriot Battery Metals’ Corvette lithium discovery—just 1.4 km from Taiga (CV8 pegmatite) and 1.5 km from Camaro (CV13 pegmatite).
Project Highlights:
- Located in the La Grande Subprovince, with geology favourable for spodumene-bearing pegmatites.
- Hellcat sits on the Vieux Comptoir Granitic suite, believed to be the source of regional lithium mineralisation.
- Initial work by Axiom Exploration identified 28 prospective pegmatite dykes.
Previous initial exploration on the James Bay Lithium Projects completed by Axiom Exploration identified 28 prospective pegmatite dykes.
