Summit outlines numerous lithium targets at its Castor project in Quebec’s James Bay

• Multiple targets have been identified following the application of remote sensing techniques

• Some of these targets include outcropping pegmatites and potential pegmatite-bearing structures at the Castor project

• Summit will conduct helicopter-supported property traverses to map and collect rock chips from the pegmatite occurrences

Summit may be a recent entrant to the sizzling James Bay lithium province in Quebec, but the explorer has already identified numerous targets at its Castor project.

Detailed satellite and radar analysis designed to detect lithium-bearing minerals has already generated over 100 targets for field investigation by rock chipping and mapping.

Significant new lithium target areas have been identified using a combination of Sentinel and ALOS-1 satellite data, historical rock geochemistry and geological features at Castor.

Summit Minerals (ASX:SUM) has also used a remote sensing study to assist with target ranking and has fast-tracked planning for exploration once the fire restrictions at the Castor project are lifted.

“The application of remote sensing techniques at Castor has culminated in us identifying multiple targets, including interpreted outcropping pegmatites and potential pegmatite-bearing structures, many with spectral and petrophysical similarities to the lithium-bearing pegmatites on Patriot Battery Metals’ nearby Corvette project and Winsome’s Cancet project,” exploration manager Jonathan King says.

With rains forecast around Castor for much of next week, Summit hopes to gain earlier access to the ground.

Highly prospective ground

In July, the company acquired 80% of the 118km2 Castor project, which consists of two contiguous blocks within the northern end of the Yasinski Lake greenstone belt.

Notably, this is the same greenstone belt that hosts Ophir Gold’s Radis lithium project and Q2 Metals’ Mia lithium project, about 18km and 32km southwest of Castor, respectively.

Since then, the company has engaged Sentinel and Radar imagery as well as scheduling a high-definition LiDAR survey to fast-track and refine exploration targeting.

This work identified broadly prospective areas of interest for pegmatite and lithium that are now being ranked and prioritised based on Sentinel and Radar responses, geological mapping and known rock geochemistry.

Emerging lithium province

The James Bay region is known for its significant mineral potential – particularly for hard rock lithium.

Highlighting its prospectivity, Allkem (ASX:AKE) recently upgraded its resources by 173% to 110.2Mt grading 1.3% Li2O – including 54.3Mt at 1.3% Li2O in the higher confidence Indicated category.

This followed closely on Patriot Battery Metals (ASX:PMT) defining at the end of July what it claims is the eighth largest spodumene deposit globally at its Corvette property with a resource of 109.2Mt at 1.42% Li2O.

Quebec is also a highly regarded tier-1 jurisdiction for lithium exploration and production due to its support for resource development, access to skilled labour and proximity to Europe and North America’s rapidly growing electric vehicle markets.

Targeting for value

While the company has already identified numerous targets and is in the process of ranking them, it also intends to fly high-resolution LiDAR towards the end of the month or early next month.

High-resolution LiDAR can overcome the impacts of thick vegetation to delineate subtle, previously obscured expressions (elevations) of bedrock, which may represent pegmatite due to its resistive nature.

Additionally, once access to the property is approved, Summit plans to carry out t 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 take about three weeks to complete.
