Summit (ASX:SUM) spot a host of pegmatite at Castor Lithium

Summit (ASX:SUM) spot a host of pegmatite at Castor Lithium

September 5, 2023 0 By Rueben Hale

Summit Minerals‘ interpretation of Sentinel-2 multispectral imagery has yielded 228 potential outcrops to add to Castor, with multiple interpreted pegmatite dykes in the eastern half of the lithium project demanding immediate attention in the Quebec end of Canada’s James Bay province.

The work from GeoCloud Analytics on the imagery has opened the early exploration phase at Castor, with field reconnaissance, mapping, and sampling ready to begin over a project covering 33 kilometres of strike in the northern end of the Yasinki Lake Greenstone belt.

Recent grab samples from Yasinki at the nearby Mia project recently averaged 2.65 per cent lithium oxide, and the orientation of dykes at Castor reflect the known spodumene-bearers found across the James Bay region.


“The work of GeoCloud expands upon earlier work completed by Dirt Exploration, resulting in several distinctive mineral occurrence clusters on the Project’s western limb that potentially reflect pegmatite and lithium-bearing minerals,” Summit Exploration Manager Jonathan King said.

“Several targets from the two work programs overlap within the Project’s central hinge, providing confidence to the targets as each consultant’s approach was independent and, yet, derived the same interpreted target.”


Summit acquired Castor with a view to being able to quickly get on the ground and start exploration for the remaining field season in the world-class jurisdiction, and now has the targets on hand to make it happen.

Next steps

A trek across the claims backed by helicopter will soon get underway for mapping and rock chip collection from the pegmatites, and interpreted Sentinel and Synthetic Aperture Radar targets and results from a high-resolution Light Detection and Ranging survey will soon be in.

Castor bears the potential for lithium-bearing pegmatite, orogenic gold, nickel, chromium, and platinum group elements, and standing well-funded, the aim is to rapidly evaluate the property’s lithium prospectivity and generate Summit’s first drill targets in its largely untouched slice of James Bay.
