GreenLight Metals Finalizes Bend Drill Plan

and Initiates Permitting on the Lobo and Lobo

East Projects

Medford, Wisconsin--(Newsfile Corp. - May 28, 2025) - GreenLight Metals Inc. (TSXV: GRL)

("

GreenLight

" or the "

Company

") is pleased to provide an update on its planned exploration activities

across its Wisconsin assets. GreenLight's strategic focus is centered on expanding known mineral

resources at its Bend Project and advancing new discoveries within the Penokean Volcanic Belt. These

efforts align with the Company's broader objective to strengthen domestic critical mineral supply chains

and reduce the United States' dependence on foreign sources.

Highlights

Bend Project Phase 1 Drilling

: 2,300-meter drill program across 8 holes targeting eastern

margin of known deposit

Historic High-Grade Results:

Previous drilling at Bend returned 67.69 meters grading 1.01% Cu

and 0.99 g/t Au, including 27.6 meters at 2.40% Cu and 1.43 g/t Au

i

Bend Phase 2 Expansion:

Planning up to 5,250 meters of drilling pending federal permit

approvals, targeting resource confirmation and strike extensions

Lobo and Lobo East Project Advancement:

Initiating permitting for high-grade zinc-copper

target at Lobo with historic intercepts of 9.4 meters grading 22.89% Zn, 1.41% Cu, 1.84% Pb, and

1.14 g/t Au

i

as well as the Lobo East Project

Strategic First-Mover Advantage:

GreenLight is one of the only active exploration companies in

the Penokean Volcanic Belt, following the departure of major miners including BHP and Rio Tinto

resulting from Wisconsin's now-lifted mining moratorium

Strategic Positioning in North America's Most Prospective VMS Belt

GreenLight's Wisconsin assets are strategically positioned within the Penokean Volcanic Belt, one of

North America's most prospective yet underexplored volcanogenic massive sulfide belts. The Belt hosts

over 15 known VMS deposits and occurrences with base and precious metal mineralization. GreenLight

maintains a first-mover advantage as currently one of the only active exploration companies in the Belt.

The Company's mission is to capitalize on this first-mover advantage to consolidate, secure, and drill

dominant land positions rich in clean energy metals copper and zinc, as well as gold, that are required to

power the green economy transition.

Matt Filgate, President & CEO, commented: "Finalizing our drill strategy for the Bend project and moving

forward with permitting for Lobo and Lobo East are exciting milestones for GreenLight. These steps

underscore our commitment to systematically advancing our assets within Wisconsin's Penokean

Volcanic Belt. We are keenly focused on executing these upcoming exploration programs, which are

designed to expand our understanding of these deposits and progress our efforts to define valuable

critical mineral resources."

Bend VMS Project - Wisconsin

The Bend VMS Project is an advanced-stage exploration asset located approximately 19 miles north of

Medford, Wisconsin. To date, approximately US$7.5 million has been invested into the project, with 53

diamond drill holes completed totaling 21,812 meters. GreenLight has secured all necessary permits to

initiate drilling and anticipates commencing its inaugural drill program in the near term. The upcoming

program will focus on delineating the deposit along a northeast strike, guided by a known VTEM

geophysical anomaly.

Historical drilling has yielded significant results, including an intercept of 67.69 meters grading 1.01% Cu

and 0.99 g/t Au, which includes a higher-grade interval of 27.6 meters at 2.40% Cu and 1.43 g/t Au (Hole

B90-06) (

see Figure 1)

.

i

These results define a near-vertical massive sulphide body hosted within felsic

volcanic rocks. A historic, non-compliant resource estimate prepared in 1992 by Jump River Joint

Ventures outlined 4.0 million tonnes at 1.74% Cu and 2.44 g/t Au.

[i]

The deposit has been traced along

strike for approximately 335 meters at surface, expanding to at least 549 meters at depth, and has been

partially tested to a vertical depth of 610 meters.

The Phase 1 drill program for 2025 will include 2,300 meters across eight holes targeting the eastern

margin of the deposit located on a leased forty-acre tract of private minerals owned by Soo Line

Railroad (

see Figure 2)

. Looking ahead, the Company plans to conduct further exploration on the

adjacent federal portions of the Bend deposit (mineral rights controlled by the Bureau of Land

Management) once the pending prospecting permit applications are approved. Phase 2 will consist of

up to 5,250 meters, including nine holes (2,500 meters) focused on resource confirmation, and six holes

(2,750 meters) testing both the eastern extension of the Bend trend and a parallel northern conductor

anomaly. The Bend ore equivalent horizon, composed of mineralized argillites with interbedded cherty-

hematitic chemical sediments, has been identified along the northeastern flank and can be traced

geophysically for at least 1.4 kilometers, representing a target for potential extensions or new deposits.

Lobo and Lobo East Projects - Wisconsin

The Lobo Project represents a high-grade VMS discovery with several mineralized intercepts ranging

from depths of 60 to 340 meters. Historical drilling highlights include 9.4 meters grading 22.89% Zn,

1.41% Cu, 1.84% Pb, and 1.14 g/t Au (Hole LB-3)

i

, demonstrating the grade potential of this proximal

occurrence to the Crandon deposit. The deposit remains open for expansion both along strike and down

dip from known mineralization. Lobo East, an optioned property totaling 476 acres with no modern

drilling, hosts two strong geophysical anomalies, with the northern target being drill-ready.

GreenLight has commenced drill targeting activities and is in the process of finalizing permit

applications for Lobo and Lobo East, which are expected to be submitted to the Wisconsin Department

of Natural Resources in the coming weeks.

Reef Gold Project - Wisconsin

The Reef Project is located approximately 12 miles east of Wausau and hosts a shear-zone-related

gold-copper system. Historical drilling, most recently conducted by Aquila Resources in 2011-2012,

intersected 65.2 meters grading 2.80 g/t Au and 0.17% Cu. (from 80.5m to 145.73m in hole R12-38),

including 8.9 meters at 13.14 g/t Au and 0.44% Cu.

i

Additional high-grade intercepts include 14.8

meters grading 14.41 g/t Au and 0.30% Cu (Hole R11-11) from 40.6m to 55.4m), including 9.3 meters at

21.3 g/t Au and 0.33%.

i

Gold mineralization at Reef occurs in eight structurally stacked, shallow zones

from surface to depths of approximately 150 meters and remains open along strike and at depth.

GreenLight intends to initiate the permitting process for a drill program in Q3 2025, with plans to

commence drilling in Q1 2026. The objective will be to test the extension of mineralization along strike

and down-dip.
