Phase 1 Exploration Completed At Redstone’s Attwood Lake Lithium Project (Ammended)

Redstone Resources Ltd (ASX: RDS) (“Redstone” or the “Company”) is pleased to announce it has completed its Phase 1 reconnaissance exploration program (Phase 1 Program) on its recently acquired Attwood Lake Lithium Project (“Attwood Lake” or the “Project”). The Company engaged APEX Geoscience to carry out a helicopter‐supported geological mapping and sampling program for lithium (Li) and rare‐earth element (REE) bearing pegmatites.

HIGHLIGHTS

• Redstone has completed a Phase 1 reconnaissance exploration program for lithium (Li) and rare‐earth elements (REE) at its recently acquired Attwood Lake Lithium Project.
• The Phase 1 program consisted of a helicopter‐supported geological mapping and sampling program for Li and REE bearing pegmatites (Figure 1).
• Numerous pegmatite outcrops were identified and a total of 209 rock grab samples were collected from various pegmatitic bodies* (Figure 2).
• The samples have been sent to the lab for geochemical assay.
• The Attwood Lake Lithium Project is located in northern Ontario and consists of 17 contiguous claims totalling 7,416 hectares.
• The Project is located in proximity to several advanced lithium projects. Numerous deposits that host significant lithium oxide (Li2O) have already been delineated in the region (Figure 3), including:
  • Seymour Lake Lithium Deposit and Root Lake‐McCombe Lithium Deposit owned by Green Technology Metals (ASX: GT1)
  • Deposits owned by Rock Tech Lithium and Infinite Ore in the Georgia Lake pegmatite field
  • Separation Rapids Lithium deposit owned by Avalon Advanced Materials Inc.
  • Frontier Lithium with the PAK and Sparks deposits

*The Company wishes to inform investors, as per ASX Listing Rule 3.1 and the Compliance Update 04/23, that the presence of pegmatite rock does not necessarily indicate the presence of lithium or rare earth element mineralisation. Laboratory chemical assays are required to determine the presence and grade of mineralisation. The Company will update the market when laboratory assays become available.

The Phase 1 Program consisted of a team of four geologists who undertook mapping and sampling at Attwood Lake (Figure 1). Numerous pegmatite showings were discovered on the Project with a total of 209 rock grab samples collected from various pegmatitic bodies.

Mapped geology for the Project consists of muscovite‐bearing granites, metasediments, migmatized supercrustal rocks, and mafic to intermediate meta‐volcanics, and foliated tonalite. Lithologies sampled during exploration included quartz dolerite (4 rocks), amphibolites (5 rocks), metasediments (8 rocks), medium‐ to coarse‐grained granites (107 rocks), pegmatitic‐ grained granites to pegmatites (83 rocks) and other (2 rocks) (Figure 2 and Appendix 1). The outcrops vary in size from a few meters and up to 10s of meters wide by 50m long. Outcrops can occur in clusters or as a single body.

Two broad categories of medium‐to coarse‐grained granitic rocks were sampled: dominantly quartz and potassium‐feldspar, with accessory minerals of biotite and more rarely garnet and apatite; and dominantly muscovite quartz and white‐feldspar. The pegmatites had similar mineralogy with some instances of tourmaline, light, blue‐coloured apatite, and rarely large grains of biotite of up to 30 cm.

The 209 samples have been sent to the laboratory for geochemical analysis.

The Attwood Lake Lithium Project is located in northern Ontario and consists of 17 contiguous claims totalling 7,416 hectares. The Project is underlain by a folded sequence of metasediments and muscovite‐bearing granites of the Archean English River subprovince (Figure 3). The Project lies in close proximity to and partially overlaps the boundary between the Uchi and English River Terranes. Notably, all major lithium deposits found in this region are located in close proximity (<20 km) to a Terrane boundary. The Archean Terrane boundaries, as well as the associated faults and folds, likely acted as conduits and pathways for fertile parental melts and late‐stage pegmatite‐forming fluids.
