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.
Figure 2: Prospectivity analysis of Sakami Lithium Project
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.

Redstone Resources
Overview
The electrification transition is well underway and has spurred a growth in demand for base metals, including nickel and copper, which most clean technologies require. The overall sentiment for these metals continues to be healthy and optimistic, even amid global economic turmoil.
Australia is supporting this growth in demand through its mining-friendly, tier-1 jurisdictions. The country is a world leader in producing and exporting a plethora of metals and minerals, including iron, copper, lithium, nickel, bauxite and gold. Overall, Australia produces significant amounts of 19 in-demand minerals from more than 350 operating mines. Australia’s Musgrave Province contains a Mesoproterozoic crystalline basement terrain that reaches across the shared borders of Western Australia, the Northern Territory and South Australia. The terrain has significant deposits of several essential metals, including nickel, platinum group elements (PGEs), copper, gold, lead, zinc, chromite, and rare earth elements (REEs). Yet, much of Musgrave remains underexplored, especially for the base metals the world now needs.
Redstone Resources (ASX:RDS) is a base and precious metals exploration company, exploring its 100-percent-owned, highly prospective West Musgrave Project, which includes the Tollu Copper deposit, located in the West Musgrave Province of Western Australia. The company’s West Musgrave Project is located proximal to BHP’s world-class Nebo-Babel nickel-copper-PGE sulphide deposit and Succoth copper (nickel, palladium) deposit, and Nico Resources’ Wingellina nickel-cobalt project. Redstone also has other pending tenement applications prospective for nickel and copper in the same region. The company is led by a management team with expertise in geology and mineral exploration, business development and corporate law, creating confidence in the team’s ability to capitalize on its assets.
The unique Musgrave terrain has already drawn the interest of notable miners, such as OZ Minerals, now owned by BHP. BHP is progressing with the development of its Nebo-Babel nickel-copper-PGE sulphide deposit, which has been estimated to have a resource of 390 million tonnes grading 0.33 percent copper and 0.30 percent nickel, for 1.2 million tonnes of contained nickel metal and 1.3 million tonnes of contained copper metal (Mea + Ind + Inf – 2012 JORC). Final regulatory approval to begin construction of the Nebo-Babel mine has been granted. Other discoveries and deposits in the area, such as the Wingellina nickel-cobalt deposit, indicate the potential of the West Musgrave region to become a significant base metal jurisdiction.
Redstone’s flagship, 100-percent-owned West Musgrave Project is situated between these two deposits — approximately 40 kilometers east of BHP’s Nebo Babel nickel-copper-PGE deposit and 50 kilometers west-southwest of Nico Resources’ Wingellina nickel-cobalt deposit. Redstone’s West Musgrave Project is highly prospective yet largely underexplored. The asset has the right geological and structural setting for large magmatic nickel-copper sulphide deposits, volcanic-hosted massive sulphide (VHMS) deposits and other large intrusive related hydrothermal systems.
Location of Redstone’s West Musgrave Project, which includes the Tollu copper deposit, in relation to the world-class Nebo-Babel Ni-Cu-PGE deposit.
The 100-percent-owned Tollu Copper Vein deposit, located within the West Musgrave Project, has a JORC-compliant indicated and inferred resource estimate of 3.8 million tonnes grading 1 percent copper, for 38,000 tonnes of contained copper with a cut-off of 0.2 percent. There is also a current estimated conceptual exploration target*, which suggests a potential for up to 627,000 tonnes of copper at Tollu. (*conceptual exploration target ranges from 31 to 47 million tonnes of mineralization at 0.8 to 1.3 percent copper, containing 259,000 to 627,000 tonnes copper.)
Redstone Resources also entered into a joint venture agreement with Galan Lithium (ASX:GLN) to acquire 100 percent of the highly prospective suite of lithium projects that include Camaro, Taiga and Hellcat in the James Bay Lithium Province in Quebec. Redstone will be the manager of the joint venture which covers 5,187 hectares of tenure. The joint venture also secured an option to acquire 100 percent of the PAK East and PAK Southeast Lithium Projects composed of 1,415 hectares in Ontario's Electric Avenue near Frontier Lithium's (Frontier) PAK Lithium Project.
An experienced management team leads Redstone with decades of experience in the mineral resources sector, with expertise in mineral exploration, mining operations and corporate finance.

Key Projects
The West Musgrave Project
The West Musgrave Project covers 237 square kilometers of highly prospective yet underexplored terrain. The asset is 40 kilometers east of the world-class Nebo- Babel nickel-copper-PGE sulphide deposit owned by BHP’s OZ Minerals, and contains suitable geological structure and settings for nickel-copper deposits. Redstone plans to continue the exploration of the asset to follow up on recent drilling and exploration results which identified numerous prospective targets.
Project Highlights:
- Promising Geological Setting: The project hosts the right geological and structural setting for large magmatic nickel-copper sulphide deposits, VHMS deposits, and other large intrusive related hydrothermal mineralizing systems.
- Excellent Exploration Results to Date:
- The 2022 RC drill campaign conducted at the West Musgrave project returned with the highest copper grade ever to be encountered at the project, with a 1 meter intersection at 18.5 percent copper from only 18 meters downhole at the Forio Prospect.
- The latest RC drilling also confirmed the presence of mafic-ultramafic nickel source target rocks at West Musgrave – drill holes TLC183 and TLC196 have intersected a Hi-Mg mafic-ultramafic intrusion with elevated nickel and chromium at the West Cigar Magnetic Target, some 7.5 kilometers northeast of the Tollu Copper Deposit.
- This is the first time potential host or source rocks for nickel, copper, cobalt and platinum group elements (PGE) have been intersected on the project, which is significant considering the western boundary of the project area is only 40 kilometers east of BHP’s (ASX: BHP) Nebo-Babel nickel-copper-cobalt-PGE deposit.
- Additional Exploration Recently Completed: Further results remain pending for the 2022 second-phase RC drilling program.
- Significant Exploration Upside: Drilling to date has focused on less than 10 percent of the project – primarily around the exposed copper veins at Tollu.

The Tollu Copper Vein Project
Redstone’s Tollu Copper Vein deposit is located within the broader West Musgrave Project and has already produced promising drilling results. Tollu hosts a giant swarm of hydrothermal copper-rich veins in a mineralized system covering an area of at least 5 square kilometers. Copper mineralization is exposed at the surface and forms part of a dilation system within and between two major shears.
Redstone has defined a JORC 2012 resource estimate for Tollu of 3.8 million tonnes grading 1 percent copper, for 38,000 tonnes of contained copper and 0.01 percent cobalt, which equates to 535 tonnes of contained cobalt, however, the company considers that this estimate may be far greater with further drilling.
Project Highlights:
- Tollu Resource Estimate: The Tollu Copper Vein deposit has a JORC-compliant resource estimate of 3.8 million tonnes grading at 1 percent copper for 38,000 tonnes of contained copper.
- Conceptual Exploration Target* May Expand Resource Estimate: A conceptual exploration target has been estimated on the Tollu Copper Vein system which suggests a potential of 627,000 tonnes of additional copper.
- Opportunities for Resource Expansion: The 38,000-tonne copper resource may be far greater with further drilling, and continued drilling at Tollu highlights opportunities for extensions of the thick high-grade copper mineralization intersected in historical drill holes, including towards shallower depth, and consequently potential opportunities to expand the Tollu resource. Drilling results from 2017 to present are not yet included in the current Tollu resource. Additionally, the source of the Tollu copper has not yet been adequately tested at depth.
- Significant Historical High-Grade Copper Results – near surface and at depth: Significant high-grade copper has been intersected at Tollu from near surface to up to 434 meters deep including with grades as high as 3.25 percent copper over 14 meters (from 25 meters depth) (TLC153) at the Forio prospect, and 10 meters at 3.4 percent copper from 424 meters deep and still open, including 5 meters at 5.3 percent copper from 427 meters deep (TLC80) at the Chatsworth prospect.
- Recent Drilling Continues High-grade Results:
- Recent drilling at Chatsworth has extended the vertical continuity of the copper mineralization in some of the historical drill holes to double that previous with at least some 100 meters of the vertical extent and open at depth and towards the surface.
- The significant, late 2021 high-grade copper intersections drilled at Chatsworth include:
- 10 meters at 2.51 percent copper from 174 meters downhole (TLC188) including:
- 3 meters at 4.71 percent copper from 175 meters downhole;
- 26 meters at 1.46 percent copper from 61 meters downhole (TLC189) including:
- 1 meter at 5.1 percent copper from 84 meters downhole;
- 16 meters at 2.88 percent copper from 74 meters downhole (TLC190) including:
- 9 meters at 4.6 percent copper from 76 meters downhole, which includes
- 2 meters at 7.62 percent copper from 76 meters downhole;
- 22 meters at 1.26 percent copper from 104 meters downhole (TLC190) including:
- 3 meters at 3.67 percent copper from 122 meters downhole; and
- 25 meters at 1.10 percent copper from 53 meters downhole (TLC192) including:
- 7 meters at 2.64 percent copper from 60 meters downhole.
- Late 2021 drilling at Forio continued the high-grade drilling results at this prospect with a single 34-meter intersection grading 1.07 percent copper from only 15 meters depth downhole (TLC181) including:
- 2 meters at 3.21 percent copper from 19 meters downhole;
- 1 meter at 2.48 percent copper from 28 meters downhole;
- 1 meter at 1.99 percent copper from 35 meters downhole; and
- 1 meter at 2.52 percent from 40 meters downhole
- Geochemical assays from the late 2022 RC drilling campaign have confirmed the highest copper grade ever intersected at Tollu with 1 meter @ 18.5 percent copper from 18 meters downhole (TLC203). The further significant high- grade copper mineralization intersections at Forio include:
- 8 meters at 4.1 percent copper from 13 meters downhole depth in drill hole TLC203, including 1 meter at 18.5 percent copper from 18 meters downhole;
- 4 meters at 1.2 percent copper from 45 meters downhole in drill hole TLC203; and
- 6 meters at 1.47 percent copper from 80 meters downhole in drill hole TLC201.
- The high-grade copper intersections in drill holes TLC201 and TLC203 extend Forio’s high-grade copper mineralization zone to a 60-meter strike length (north and south) of continuous high-grade copper.
- The recent Forio drilling has shown that thick high-grade copper lenses have the potential to extend over significant distances along strike and to depth.
- Simple Oxide Copper Opportunity: The significant intersections of Tollu mineralization up to the surface supports investigation of a simple oxide copper resource opportunity – the Tollu drilling from 2017 to date suggests a potential for an increase from 8,000 tonnes of oxide copper already defined in the Tollu resource.
