Summit Minerals (ASX:SUM) – 228 Pegmatites Identified at Castor Lithium Project

Summit Minerals Limited (ASX:SUM) < 1 mins read


  • 228 potential pegmatite outcrops identified via interpretation of Sentinel-2 multispectral imagery.
  • Multiple interpreted pegmatite dykes in the eastern half of the Castor property demand immediate attention.
  • High-resolution LiDAR survey complete with results due soon.

Summit Minerals Limited (Summit or the Company) is pleased to announce the results of the recent interpretation of Sentinel-2 Multispectral Imagery for the identification of outcropping potential lithium (Li)-pegmatite within the Castor Project of the James Bay area, Quebec. For Castor, 228 potential pegmatite outcrops were located within the claim boundaries.

Summit engaged GeoCloud Analytics (GeoCloud) to source, process, and interpret Sentinel-2 Multispectral Imagery for the identification of outcropping potential Li-pegmatite within the Castor Project. This work identified potential outcrops for field reconnaissance, mapping, and sampling in the early exploration phase.

Exploration Manager, Mr Jonathan King, stated, “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. 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.”

Next Steps:
Summit will soon conduct helicopter-supported property traverses to map and collect rock chips from the pegmatite occurrences and the interpreted Sentinel and SAR targets. This work is expected to be completed this quarter.
