Comet Lithium Launches Follow-up
Exploration Program for Recently Announced
High-Grade Caesium-Lithium Pegmatite
Discovery at Elmer East
The pegmatite discovery dyke measures 1–2 metres in width and has been traced for ~80 metres
in outcrop, as previously disclosed on
August 19, 2025
, it remains open to the east with its western
extent pinching out, it hosts spodumene with muscovite and tourmaline consistent with highly
evolved LCT pegmatite systems, and to date only two grab samples have been collected, both
returning high assay results.
Highlights:
Follow-up program designed to test the extent of the strike, evaluate widths, and explore for
additional pegmatites, as these systems often occur in clusters, building on the recent caesium-
lithium pegmatite discovery and aiming to expand the property's mineralization potential.
Fieldwork scheduled to begin
October 15, 2025
, in collaboration with Dahrouge Geological
Consulting Ltd.
Three geological teams to conduct mapping, prospecting, sampling, and channel work across
high-priority zones

/CNW/ - Comet Lithium Corporation (TSXV: CLIC) (FSE:
8QY) ("Comet Lithium" or the "Corporation") is pleased to announce the launch of its Fall 2025
Phase 2 Exploration Program at 100%-owned Elmer East Property, located in the Eeyou Istchee
James Bay region of the province of Québec.
Prospecting Program: A Targeted Follow-Up Program Near Discovery
The follow-up program, conducted with Dahrouge Geological Consulting Ltd., will span several days
and deploy three field teams to complete detailed prospecting, structural mapping, traverses,
sampling, and channel work in and around the newly discovered pegmatite occurrence. Priority
zones, highlighted in Figure 1, represent areas most prospective for additional caesium-lithium
mineralization.
Elmer East Property
Exploration to date has outlined several high-potential corridors, with follow-up work now focused on
extending known mineralization along strike and testing for new outcrops or sub-cropping pegmatites
across the broader Elmer East land package.
"The discovery of a caesium-lithium pegmatite at Elmer East earlier this year confirmed the
property's strong potential," said
Vincent Metcalfe
, Chair and CEO of Comet Lithium. "This fall
program is designed to build on that success by systematically testing the highest-priority targets
near the existing Caesium discovery. With three experienced field crews and the support of
Dahrouge, we are confident this work will critical insights into the scale and continuity of
mineralization, positioning Comet Lithium for the next stage of growth."
