GreenLight Metals Signs Binding Term Sheet with Barrick for

Staged Earn-In Joint Venture at Kalium Canyon Project in Nevada’s Walker Lane

May 7, 2026 – MEDFORD, WI. GreenLight Metals Inc. (TSXV: GRL) (OTCQB: GRLMF) (“GreenLight” or the

“Company”) is pleased to announce that, through its wholly owned subsidiary Green Light Wisconsin LLC, it

has signed a binding term sheet (the “T erm Sheet”) with a wholly owned subsidiary of Barrick Mining

CorporaKon (“Barrick”), for a proposed staged earn-in and joint venture at GreenLight’s Kalium Canyon gold

project in Esmeralda County, Nevada (the “Property” or “Kalium Canyon”).

Pursuant to the Term Sheet, Barrick may earn an iniKal 60% project-level equity interest by compleKng US$7.5

million in Qualifying ExploraKon Expenditures (“QEE”), limited to direct project costs, and making aggregate

cash payments of US$1.0 million to GreenLight over a six-year Stage 1 earn-in period. Following Stage 1 vesKng,

the parKes expect to implement the joint venture through a project company or other mutually agreed holding

structure, with Barrick as operator. Aaer the Stage 1 earn-in, Barrick may elect to earn an addiKonal 10%

interest by funding an addiKonal US$12.0 million of QEE over a four-year Stage 2 earn-in period, and thereaaer,

Barrick may elect to earn up to an 80% aggregate interest by compleKng a pre-feasibility study on the Property

at its sole cost within 48 months under a Stage 3 earn-in period. During the Stage 1 through 3 earn-in periods,

all costs, expenditures, work programs, budgets and studies required to earn the addiKonal interests, including

costs related to any pre-feasibility study, will be funded solely by Barrick.

Although the Term Sheet is binding, the parKes have not yet entered into a long form agreement. CompleKon

and implementaKon of the long form agreement remain subject to, among other things, final documentaKon,

applicable third-party noKces, consents, waivers, and other customary condiKons.

Mah Filgate, President & CEO of GreenLight, commented: “Securing a binding term sheet with Barrick is a

significant validaKon of Kalium Canyon’s geological potenKal. Barrick’s technical team brings unmatched

epithermal experKse in Nevada, and their track record of discovery and development success, including the

world-class Fourmile discovery, makes them the ideal partner to advance the Property. The staged structure

allows Barrick to fund exploraKon and any pre-feasibility work through to an 80% interest while preserving

meaningful upside for GreenLight.”

Summary of Key Commercial Terms

• Binding Term Sheet and Long Form DocumentaQon: The Term Sheet sets out the principal terms of a

Barrick as operator . If Barrick elects to conKnue with the Stage 2 or Stage 3 earn-in, all costs,

expenditures, work programs, approved budgets and studies used by Barrick to earn the addiKonal

interest, including all PFS Costs, will be funded solely by Barrick. GreenLight will not be required to fund

Stage 2 or Stage 3 programs or budgets during Barrick’s earn-in. PFS Costs will be funded solely by Barrick

the applicable earn-in right lapses or expires, Barrick will retain only its vested 60% or 70% interest,

respecKvely.

• DiluQon and AutomaQc Exit: Following the earn-in period, diluKon and default mechanics will apply

under the joint venture. If GreenLight’s interest is diluted below 10%, its interest will be automaKcally

sold to the majority shareholder at fair market value, determined without min ority discount,

illiquidity/marketability discount or similar discount, and GreenLight will exit the joint venture.

About the Kalium Canyon Project

• LocaQon & Se_ng: Kalium Canyon lies in Esmeralda County, Nevada, within the Walker Lane trend—

one of the United States’ most prolific belts of volcanic-hosted epithermal systems—and sits inside the

Silver Peak Caldera adjacent to its northeastern wall. The project area is underlain by Miocene volcanic

rocks and structurally prepared northeast-trending faults typical of the district.

• Land Package: The Property comprises 135 federal unpatented lode mining claims organized around

two target areas: the historic ArgenKte prospect and the Kalium structural zone to the west. The total

land posiKon is approximately 2,758 acres (1,117 ha).

• Deposit Model: Targets at Kalium Canyon best fit a low-sulfidaKon epithermal model characterisKc of

the Walker Lane trend. Regionally important epithermal systems in this belt include Aurora, Bullfrog,

Comstock, Rawhide, Round Mountain and Tonopah.

• Kalium Structural Zone (Western Block): Mapping and spectral work define a 1–2 km corridor of

alunite–kaolinite (“steam-heated”) alteraKon—an upper-system paleosurface that is consistent with a

buried epithermal system. Rock samples from this steam-heated area are not anomalous in gold but

show elevated mercury and arsenic pathfinders.

• ArgenQte Prospect (Eastern Block): The main mineralized body, the Adit Zone, is a broad zone of gold-

bearing quartz veins, breccia and stockwork hosted by variably silicified, argillic laKte porphyry. Mapping

traces the zone for approximately 2,000 a (610 m) with widths locally up to 270 a (82–83 m).

• Historic Sampling & Drilling at ArgenQte: An 80-a adit completed in 1947 with 167 a of conKnuous chip

sampling reportedly averaged 1.97 g/t Au; Camnor Resources later reported chip results including 50 a

at 3.74 g/t Au. Historical reverse-circulaKon drilling intersected broad mineralized intervals, including

270 a at 0.86 g/t Au near the adit, with internal higher-grade secKons such as 5 a at 9.85 g/t Au.

The sampling and reverse-circulaKon drill intercepts summarized above are historical in nature. As set out in

the Company’s NI 43-101 technical report, the report author was unable to verify the underlying data, including

original assay cerKficates, drill core or cukngs and complete logs, or confirm true widths. These results should

not be treated as current and are provided for context only. See GreenLight’s technical report on SEDAR+ at

Quadrangle, Esmeralda County, Nevada, USA; effecKve January 12, 2022; prepared by Aurora Geosciences Ltd.

(Peter E. Bihenbender, CPG).
