GREENLIGHT METALS ENGAGES TACONITE DRILLING FOR BEND DRILL PROGRAM AND FILES NOTICE OF INTENT TO DRILL WITH WISCONSIN DNR

Greenlight Metals Inc.'s wholly owned subsidiary, Green Light Wisconsin LLC (GLW), has engaged Minnesota-based Taconite Drilling LLC as the drill contractor for the company's upcoming exploration program at the Bend VMS (volcanogenic massive sulphide) project in Wisconsin. Additionally, GLW has provided formal notice to the Wisconsin Department of Natural Resources (WDNR) that drilling operations will commence shortly.

Highlights

• Drill contractor secured: GLW has engaged Taconite Drilling, a veteran-owned drilling firm headquartered on Minnesota's Iron Range with more than five decades of combined diamond-drilling experience and a strong safety-first culture.
• Mobilization imminent: Drill crews and equipment are expected to begin mobilizing to site June 16, 2025, with drilling slated to start later that week.
• Regulatory milestone: GLW submitted its notice of intent to drill to the WDNR on June 10, 2025, clearing the final procedural step before field activities commence.
• Program scope: Phase 1 comprises approximately 2,200 metres of core drilling across eight holes, targeting extensions along the eastern margin of the Bend copper-gold VMS deposit.

Bend project phase 1 drilling program

As previously announced on May 28, 2025, Greenlight's phase 1 drill program at the Bend project will comprise approximately 2,200 metres across eight drill holes targeting the eastern margin of the known deposit. The program will focus on a leased 40-acre tract of private minerals owned by Soo Line Railroad, where all necessary permits have been secured. The phase 1 program is expected to take approximately five weeks to complete.

The Bend project is a copper-gold VMS deposit that has seen approximately $7.5-million (U.S.) in historical investment, with 53 diamond drill holes completed totalling 21,812 metres. Historical drilling has yielded significant results, including 67.69 metres grading 1.01 per cent Cu (copper) and 0.99 g/t (gram per tonne) Au (gold), with a higher-grade interval of 27.6 metres at 2.40 per cent Cu and 1.43 g/t Au.

Matt Filgate, president and chief executive officer, commented: "With Taconite engaged and our WDNR notice now filed, we are positioned to launch our maiden drill program at Bend and begin unlocking the potential we see in Wisconsin's Penokean volcanic belt. Taconite's regional expertise and proven track record in mineral exploration drilling make them an ideal partner for this important program. We look forward to testing our targets and building on the significant historical work completed to date."
