Redstone Resources launches reconnaissance exploration at Attwood Lake Lithium Project, Canada

Base and precious metals developer Redstone Resources (ASX:RDS) has begun a reconnaissance exploration program at its Attwood Lake Lithium Project in Ontario, Canada.

The company reports it has engaged APEX Geoscience to undertake a helicopter-supported geological mapping and sampling program for lithium and rare earth element (REE) bearing pegmatites. APEX’s crew has mobilised to Pickle Lake to begin the stage one initial program.

The Attwood Lake Lithium Project lies in northern Ontario and consists of 17 contiguous claims covering 7,416 hectares. Redstone says the project is underlain by a folded sequence of metasediments and muscovite-bearing granites of the Archean English River subprovince. Additionally, the project lies near and partially overlaps the boundary between the Uchi and English River terranes.

Redstone reports all ‘major’ lithium deposits found in this region lie close to a terrane boundary

Redstone reports all ‘major’ lithium deposits found in this region lie close to a terrane boundary. The Archean Terrane boundaries, as well as the associated faults and folds, act as conduits and pathways for ‘fertile’ parental magmatic melts and late-stage pegmatite-forming fluids.

Historical exploration work surrounding the project area includes a diamond drill program targeting massive sulphide mineralisation completed in 2004 for US-based East West Resources Corp on claims directly northwest of Attwood Lake.

This program saw 7 drillholes completed, with 5 encountering pegmatite intervals of up to about 70m. These pegmatite intervals were not assayed for lithium or REE.

In 2016, a reconnaissance mapping program undertaken by the Ontario Geological Survey (OGS) resulted in the identification of numerous pegmatite occurrences in outcrop north of Attwood Lake. However, the OGS survey did not cover the Attwood Lake project area.

Many of the pegmatitic rock samples were collected within the metasedimentary rock unit, which extends throughout Attwood Lake. Redstone says several of these pegmatite occurrences were mapped in proximity to a regional northeast-southwest oriented fold axis, which extends southwest through the western portion of Attwood Lake.

Redstone Resources is an ASX-listed base and precious metals developer exploring its West Musgrave Project in Western Australia, which includes the Tollu copper deposit.

West Musgrave lies between BHP’s (ASX:BHP) Nebo Babel deposit and Nico Resources’ (ASX:NC1) Wingellina Nickel-Cobalt Project. Along with West Musgrave, the company is continuing to evaluate the HanTails Gold Project in Kalgoorlie for potential development.

The company also entered into an option agreement in May 2023 to acquire the Attwood Lake Area Lithium Project in Canada.
