Comet Lithium to Launch 2025 Exploration Program at Triple L and Elmer East Properties, Targeting Copper-Nickel and Lithium Anomalies

Comet Lithium to Launch 2025 Exploration

Program at Triple L and Elmer East

Properties, Targeting Copper-Nickel and

Lithium Anomalies

Highlights:

Fieldwork to commence on

June 13th

at the Triple L and

Elmer East

properties, in collaboration

with Dahrouge Geological Consulting Ltd.

Intensive surface exploration program will include 35 traverses across high-priority targets.

Triple L Property exploration will focus on refining MAG and TDEM anomalies using a Beep Mat

to identify potential copper-nickel mineralization.

The 17-day program will involve two experienced field teams, with Comet's VP of Exploration,

Vincent Cardin-Tremblay, actively participating in the exploration efforts.

/CNW/ - Comet Lithium Corporation (TSXV: CLIC) (FSE:

8QY) ("Comet Lithium" or the "Corporation") is pleased to announce the launch of its 2025 Phase 1

Exploration Program, set to begin on

June 13, 2025

, on its 100%-owned Triple L and

Elmer East

properties in the Eeyou Istchee James Bay region of the province of Québec.

Prospecting Program: A Targeted, First-Pass Program

Comet's 17-day field campaign will be conducted in partnership with Dahrouge Geological Consulting

Ltd., adding proven technical expertise to the Corporation's exploration efforts. Two experienced

field teams will carry out investigation, detailed mapping, sampling, and traverses across 35 planned

lines in areas deemed most prospective for mineralization (shown in red in Figures 1 to 5 below).

Triple L Property

High-priority targets at Triple L Property were identified and selected through the interpretation of

2024 high-resolution magnetic (MAG) and time-domain electromagnetic (TDEM) survey results,

alongside satellite image interpretation. Several prospective anomalies will be investigated by the

field team, with support from a Beep Mat to refine target detection for potential copper-nickel

mineralization. These high-priority zones are highlighted in red on the maps (see Figure 1).

Geophysical surveys are not definitive, and the results are still at an early stage of interpretation,

with no guarantee of a mineral discovery.

The Beep Mat is a portable electromagnetic survey instrument that continuously records subsurface

readings as it is pulled along the ground by an operator. It emits a distinctive audible "beep" when a

conductive body is detected within approximately three metres.

Elmer East Property

At the Elmer East Property, priority prospecting targets were identified via satellite image analysis.

The high-priority zones, shown in red (Figure 2), represent areas where bedrock is most likely

outcropping or sub-outcropping, with potential for lithium-bearing pegmatites. Several outcrops have

been identified in the southern block of the Elmer East Property.

"We're excited to kick off the 2025 exploration program at our Triple L and

Elmer East

properties,"

said

Vincent Metcalfe

, Chair and CEO of Comet Lithium. "This initial phase is a critical step in

advancing our portfolio, and our systematic, first-pass approach is designed to efficiently evaluate

multiple high-priority target areas. At Triple L, identifying copper-nickel showings is a key focus, and

our early geophysical interpretation and satellite analysis have revealed highly promising anomalies.

With the expertise of our field teams and partners, we're well positioned to uncover meaningful

mineralization and unlock the broader potential of both properties."
