High Upside Lithium Project Located in the Windimurra Igneous Complex
Canegrass Lithium Project
Key Facts
About the Canegrass Lithium Project
The project covers an area extending over part of the Windimurra Igneous Complex, a large differentiated layered ultramafic to mafic intrusion emplaced within the Yilgarn craton of Western Australia. It is conical to a sheet-like body intruded into the Archaean granite-greenstone terrain of the Murchison Province, outcrops over an area of approximately 2,500 km2 and has an age of approximately 2800 Ma. The complex is dominantly comprised of basic cumulate rocks that can broadly be classified as gabbroic in composition. Magmatic layering dips inwards at the margins and flattens in the centre. It is dissected by large scale strike-slip shear zones so that the original extent of the complex is unknown. The Windimurra Igneous Complex is part of a much larger suite of similarly layered ultramafic to mafic bodies emplaced between 2,700-2,800Ma across the Murchison Province. Collectively, these complexes are similar in thickness, volume, and composition to the Bushveld Igneous Complex of South Africa.
About the Canegrass Lithium Project
The project is predominately underlain by the lower zone of the Windimurra Intrusive Complex, a series of olivine-rich gabbro and gabbronorite which grade upwards into more leucocratic gabbroic rocks. The Lower zone is separated into a western and eastern lobe by the Shephards Discordant Zone (“SDZ”), which represents a significant break in the igneous stratigraphy and is characterised by magnetite and magnetite-bearing gabbro. To the east of the SDZ lies a package of mafic volcanic rocks, felsic volcaniclastic sandstones, and banded iron-formation bounded by the Wyemandoo Shear Zone and are part of the Norie Group.
About the Canegrass Lithium Project
Historic exploration completed by Aldoro has consisted of satellite imagery interpretation, geochemical sampling, rock chip sampling and an initial phase of drilling. Due to the high degree of outcrop exposure and lack of vegetation, satellite imagery interpretation provides a rapid low-cost evaluation method to initially review and target pegmatite swarms. A satellite imagery-based interpretation was conducted by HMAN across the entirety of the Canegrass Lithium Project and revealed extensive swarms of what is being interpreted as pegmatites. These interpreted pegmatites are located within the same lithologies and setting as that at Aldoro’s Project. Furthermore, rock chip sampling conducted by Aldoro has confirmed the presence of high-grade rubidium with associated lithium mineralisation 1,400 m to the east of the Canegrass Lithium Project.
