Summit Minerals (ASX: SUM) Numerous targets identified at the Castor Lithium Project

Summit Minerals Limited (ASX: SUM) 2 mins read

Summit Minerals Limited (ASX: SUM, “Summit” or the “Company”) is thrilled to provide an update to its shareholders regarding the ongoing exploration activities at the Castor Lithium Project located in the renowned James Bay area.

Key Developments:

  • A comprehensive satellite and radar analysis, specifically designed to detect lithium-bearing minerals, has identified over 100 potential targets for subsequent field investigation through rock chipping and mapping.

  • Significant new lithium target areas have been pinpointed, leveraging Sentinel and ALOS-1 footprints, historical rock geochemistry, and unique geological features present at Castor.

  • The remote sensing study has been instrumental in target ranking, expediting the planning for exploration. This comes in anticipation of the lifting of fire restrictions at the Castor Project.

  • The Castor Lithium Project boasts several mapped pegmatite occurrences and spans over a 33km strike length of the Yasinski Lake Greenstone Belt. Notably, spodumene-bearing pegmatites are hosted within this belt, extending along-strike to the southwest.

  • A high-resolution LiDAR survey is on the cards for late August to early September.

The Company has been proactive in its exploration approach, employing Sentinel and Radar imagery. This is in conjunction with scheduling a high-definition LiDAR survey. The objective is clear: to accelerate and hone exploration targeting while awaiting access post the fire risk.

Dirt Exploration, with its principal Dr. Neil Pendock at the helm, was commissioned to acquire, process, and analyze Sentinel Multispectral data (Sentinel) and Synthetic Aperture Radar (SAR) over the Castor Lithium Project. This meticulous work has spotlighted areas with high potential for pegmatite and lithium. These areas are now undergoing ranking and prioritization based on Sentinel and Radar feedback, geological mapping, and established rock geochemistry. Once the fire risk diminishes, these study results, inclusive of the previously identified pegmatite, will pave the way for over 100 targets suitable for helicopter-based exploration activities.

It's worth noting that the Castor Project's strategic location places it on the same greenstone belt, a mere 18km from the recent lithium discoveries by Ophir Gold at its Radis Project and 32km from Q2 Metals’ Mia Lithium Project. The primary pegmatite trend mirrors this boundary, extending from Patriot Battery Metals’ Corvette Project, passing through Winsome Resources’ Cancet Project, and taking a southwest turn near the Castor Project.

In the words of the Exploration Manager, Mr. Jonathan King,

“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”.
