Redstone Resources Limited (ASX: RDS) (Redstone or the Company) is pleased to announce results for returned assays from its Phase 1 reconnaissance exploration program (Phase 1 Program) on the Attwood Lake Lithium Project (“Attwood Lake” or the “Project”) located in northwestern Ontario, Canada.
HIGHLIGHTS
- Numerous pegmatite outcrops identified from the Phase 1 Exploration Program on Redstone’s Attwood Lake Lithium Project, located in northwestern Ontario, Canada.
- The Phase 1 program consisted of a helicopter‐supported geological mapping and sampling program for lithium (Li) and rare‐earth element (REE) bearing pegmatites.
- Results from the 209 rock grab samples collected indicate elevated Li is present across the Project.
- Numerous rock grab samples have returned Li assays above background levels. Seven samples returned Li assays at three times background levels.
- The Phase 1 Program and results indicate elevated Li is present across the Project with the largest and most prospective pegmatites found in the western portion of the Project.
- The mineralogy and geology observed across the entire Property is permissive to host potentially anomalous lithium concentrations.
- The Project is road accessible via 2 forestry roads on both sides of the property.
The helicopter‐supported reconnaissance program focused on geological mapping and sampling for lithium (Li) and rare‐earth element (REE) bearing pegmatites. Samples were collected from outcrops that varied in size from a few meters up to 10s of meters wide by 50 m long. Sampling concentrated on the largest accessible pegmatite bodies observed from the air with a total of 209 rock samples collected from various pegmatitic bodies on the Project (Figures 1 and 2, Appendix 1). At least a further 10 pegmatite bodies were identified from the air but are yet to be sampled.
The Phase 1 Program and results obtained to date indicate that elevated lithium is present across the Project. The western half of the Project is considered the most prospective due to the abundant pegmatite exposures in the area which returned the highest lithium concentrations (Figure 4). These pegmatites are hosted within metasediments and comprise the largest pegmatites found on the Project to date.

The collected rock samples were analysed at ALS Global Laboratories in Thunder Bay, Ontario, Canada, using a standard 4‐acid digestion for a suite of 48 elements. The samples returned lithium concentrations up to 78.9ppm. Seven grab samples comprising pegmatitic‐grained granites to pegmatites, medium‐ to coarse‐grained granites and other lithologies (Figure 3) from across the Project yielded Li assay values greater than 60 ppm (three‐times background levels; Figure 4).

The highest assay sample F0031340 (78.9 ppm Li) was collected from a large pegmatite body that extends over 200 m in length and trends east‐west. Sample F0031006 (72.5 ppm Li) was collected along a trend of pegmatite bodies that extend over 800 m in length, with individual pegmatites reaching approximately 50 m in length. Follow up sampling in these areas is proposed to test the entire extent of the pegmatites.

Investor Insight
Redstone Resources' (ASX:RDS) strategic exploration of copper and other base metals in Western Australia's West Musgrave region, coupled with its lithium acquisition in Canada, positions the company to potentially capitalize on the growing global demand for battery metals, leveraging its 100 percent ownership of its West Musgrave project and proximity to significant existing deposits.
Overview
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. Australia produces significant amounts of 19 in- demand minerals from more than 350 operating mines. The 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 base metals 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 BHP. BHP has progressed with the development of its Nebo-Babel nickel-copper-PGE sulphide deposit, following grant of final regulatory approval to begin construction of the Nebo-Babel mine. The Nebo-Babel nickel-copper-PGE sulphide deposit 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). 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 kilometres east of BHP’s Nebo Babel nickel-copper-PGE deposit and 50 kilometres 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*, suggesting 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.)
Outside Australia, Redstone Resources is an emerging battery metals explorer and has been building its portfolio of lithium and other critical mineral assets in Canada.
Redstone Resources also recently entered into a 50/50 joint venture agreement with Galan Lithium (ASX:GLN), aqcuiring 100 percent of the highly prospective suite of lithium projects that include the Camaro, Taiga and Hellcat Projects located in the prolific James Bay Lithium District in Quebec, host to several advanced lithium projects and new lithium discoveries in Canada including:
- Patriot Metals (ASX:PMT,TSXV:PMET) Corvette Project
- Winsome Resources Ltd (ASX:WR1) Cancet Project; and
- Q2 Metals Corp (TSXV:QTWO) Mia Lithium Project.
Patriot’s CV8 pegmatite discovery is located only 1.4 km north of the Taiga Project and the newly discovered CV13 pegmatite cluster is located 1.5 km north of the Camaro Project
Redstone will be the manager of the joint venture which covers 5,187 hectares of tenure.
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 Projectcovers 237 square kilometres of highly prospective yet underexplored terrain. The asset is 40 kilometres east of the world-class Nebo-Babel nickel- copper-PGE sulphide deposit owned by BHP, 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.
Significantly, recent drilling some 7.5 km northeast of the Tollu Copper Vein deposit has confirmed for the first time the presence of mafic-ultramafic intrusions on the project, which are potential host and/or source rocks for nickel-copper-PGE ± cobalt mineralisation. This confirmation is significant for Redstone especially considering the western boundary of the project area is only 40 kms east of the BHP-owned world-class Nebo Babel nickel-copper-cobalt-PGE deposit and may also be a potential explanation for a source of the high grade copper 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 kilometres.
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 tonnesgrading 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.
Drilling results from Redstone Resources’ most recent exploration program continue to deliver outstanding copper results for the Chatsworth and Forio prospects at the Tollu Copper Vein deposit.
At Chatsworth, recent RC drill hole TLC205 intersected 11 metres at 1.2 percent copper from only 29 metres downhole, extending the previously intersected high‐grade copper lens a further 20 metres towards the surface.
Together with previous drilling, TLC205 has shown that the targeted high grade copper lens at Chatsworth is up to 26 metres thick (downhole), has a copper grade always over 1 percent copper and extends over 140 metres vertical from TLC205 to its deepest intersection to date in TLC188 at 174 metres-184 metres downhole. No drilling has been tested beneath the intersection in TLC188 and so this significant, up to 26 metre thick (downhole) vertically long high-grade copper lens remains open at depth.
Previous significant intersections at Chatsworth also include:
- TLC188 - 10m at 2.51 percent Cu from 174m downhole including:
- 3m at 4.71percent Cu from 175m downhole;
- TLC189 - 26m at 1.46 percent Cu from 61m downhole including:
- 1m at 5.1percent Cu from 84m downhole;
- TLC033 - 5m at 2.21percent Cu from 100m downhole; and
- TLC034 - 15m at 1.39 percent Cu from 136m downhole including:
- 3m at 3.67 percent Cu from 122m downhole.
E-W Cross-section of high grade copper lens at Chatsworth Prospect, Tollu Copper Deposit. Recent intersection in RC drill hole TLC205 is shown along with intersections from 2021 drilling in TLC188 and TLC189 as well as intersections in historical drilling, RC drill holes TLC033 and TLC034
Recent drilling has also delivered further high-grade intersections at Forio, including the highest Cu grade ever intersected with 1 m at 18.5 percent copper from 18 m downhole in RC drill hole TLC203.
Drilling completed at Forio in late 2022 RC drilling campaign at Tollu were aimed at testing the continuity along strike of a zone of high grade copper lenses at Forio identified in previous drilling.
The high grade Cu intersections at Forio include:
- 8 m at 4.1 percent copper from 13 m downhole depth (TLC203) including 1 m at 18.5 percent copper from 18 m downhole.
- 4 m at 1.2 percent copper from 45 m downhole (TLC203)
- 6m at 1.47 percent copper from 80 m downhole (TLC201).
The significant drilling intersections of high‐ grade copper mineralisation at both the Chatsworth and Forio Prospects (dating back to 2017) at Tollu are yet to be included in the existing JORC 2012 Tollu resource estimate.
Redstone and Galan 50/50 Joint Venture
James Bay Lithium Projects - Taiga, Camaro and Hellcat
The Redstone and Galan 50/50 JV recently acquired the James Bay Lithium Projects, namely three high quality projects consisting of Taiga, Camaro and Hellcat Projects (TCH). The projects cover 3,850 hectares and are adjacent to Patriot Battery Metals’ (TSXV:PMET) Corvette Lithium discovery in James Bay. PMET’s CV8 pegmatite is one of the finest new hard rock lithium discoveries, with grab samples averaging 4.6 percent lithium oxide Li2O, and is located only 1.4 kilometres north of the Taiga Project. PMET’s newly-discovered CV13 pegmatite cluster is located 1.5 kilometres north of the Camaro Project.
James Bay Project Highlights:
The Taiga and Camaro are situated in the Meso-Archean to Paleoproterozoic La Grande Subprovince of the Superior Province underlain by the Poste Le Moyne and Langelier plutons, respectively. The Camaro project is hosted in the Semonville Pluton with local windows of the Rouget Formation metabasalt. Properties are hosted in hornblende biotite diorite, quartz-rich diorite, biotite hornblende tonalite, granodiorite, granite, conglomerate, wacke, and amphibolite. The Hellcat Project hosts Vieux Comptoir Granitic suite believed to be the source of the spodumene-bearing pegmatite dykes found within the region. The primary greenstone within the project is amphibolites of the rouget greenstone belt, a similar age to the Grupe de Guyer greenstone belt, located within Patriot Battery Metals Corvette discovery.
Previous initial exploration on the James Bay Lithium Projects completed by Axiom Exploration identified 28 prospective pegmatite dykes.

High grade Massive Sulphide Intercepts Confirmed at Oval
HIGHLIGHTS:
- OVD027 confirms the continution of high grade massive sulphide from OVD0211 with an intercept of 6.1 metres of 4.16% Cu, 3.51% Ni, 0.G3g/t E3, and 0.13% Co from G8.2 metres encountered between broader high grade zones of:
- A dense disseminated intercept - 26.2 metres of 0.44% Cu, 0.52% Ni, 0.12g/t E3, and 0.03% Co from 72.0 metres and
- A net textured intercept - 15.3 metres of 1.15% Cu, 0.79% Ni, 0.35g/t E3, and 0.04% Co from 104.3 metres;
- A high grade broad intersection is confirmed at the central part of the Oval area by OVD026. It includes a massive sulphide intercept in hole OVD026 of 1.8 metres of 3.21% Cu, 3.32% Ni, 0.6Gg/t E3, and 0.14% Co from 105.0 metres within broader mineralisation of:
- 19.8 metres of 1.23% Cu, 0.98% Ni, 0.36g/t E3, and 0.05% Co from 91.2 metres.
OVD026 is located 100 metres northwest of the previously announced 8.8 metres of massive sulphide identified in drillhole OVD021.
On completion of the Phase 2 exploration work and receipt of all assays, Managing Director Gan-Ochir Zunduisuren, commented:“The 2024 Phase 1 and 2 drilling and exploration programs have confirmed the broad presence of high-grade mineralisation in the Oval gabbroic intrusion. The grades intercepted in some of the drillholes are exceptional and may be indicative of broader potential over a larger area, given Oval is a greenfields discovery.
The 2025 exploration program will focus on obtaining information on the size/metal content potential of the Oval Cu-Ni-PGE mineral system as well as targeting the possible deeper magmatic sources at Oval. Broader exploration is also planned at potential extensions of Oval and nearby look-a-like prospects. We look forward to updating shareholders on progress, with drilling expected to commence in around 8 weeks”.
Summary of Phase 2 exploration drilling at Oval Cu-Ni-PGE project
The Company’s recent drilling work has predominantly focused on finding high-grade mineralisation in the olivine-amphibole gabbro at the Oval project. The multiple intercepts of massive sulphide mineralisation with different ratios of metal contents throughout the Oval gabbroic intrusion is highly encouraging for the presence of one or more deeper sources of high grade mineralisation in the opinion of ABM.

Drillhole OVD02c
Drillhole OVD026 was designed to test the Down-Hole Electromagnetic (DHEM) conductor plate identified as OVD007_L2_B (reinterpretation of OVD007_L2_A2 by Southern Geoscience Consultants), which exhibits a conductance of 1,000 siemens. The drilling intersected a total of 1G.8 metres of mineralisation with 1.23% Cu, 0.G8% Ni, 0.36g/t E3, and 0.05% Co from G1.2 metres including;
- 4.8 metres of @ 0.45% Cu, 0.43% of Ni, 0.14g/t E3, and 0.02% Co of dense disseminated mineralised gabbro from 91.2 metres,
- 6.6 metres of @ 1.56% Cu, 0.G0% Ni, 0.50g/t E3, and 0.04% Co of net textured mineralisation from G6.0 metres,
- 2.4 metres of @ 1.52% Cu, 1.3G% Ni, 0.43g/t E3, and 0.07% Co of semi massive sulphide mineralisation from 102.6 metres,
- 1.8 metres of @ 3.21% Cu, 3.32% Ni, 0.6Gg/t E3, and 0.14% Co of massive sulphide mineralisation from 105.0 metres, and
- 4.2 metres of @ 0.57% Cu, 0.45% of Ni, 0.21g/t E3, and 0.02% Co of dense disseminated mineralised gabbro from 106.9 metres (Table 1 provides a detailed breakdown of mineralisation intervals).
OVD026 is located in the Oval area, which is approximately 100 metres northwest of the previous intersection identified in drillhole OVD0213. This intercept may represent an extension of the known massive sulphide mineralisation in the Oval area and highlights the potential for further expansion of massive sulphide zones within the broader prospect area (Figures 1 and 3).
