Stardust Metals Moves to Quantify Gold Opportunity from Kerr-Addison Tailings

Executive Summary of May 19, 2026 Release

• Stardust Metal Corp. has commenced a sonic drilling program at the McGarry Project to evaluate the historic Kerr-Addison tailings deposit in the Kirkland Lake Gold Camp.
• The target asset is an estimated 40 million tonne tailings accumulation.
• Drilling methodology utilizes sonic technology on approximately 100-metre centres to recover continuous core samples for accurate grade and density data.
• Program objectives include evaluating vertical/lateral grade continuity, determining volumetric extent, assessing material density/moisture, and characterizing metallurgical characteristics.
• Metallurgical testing is targeted for completion in Summer 2026.
• A NI 43-101 mineral resource estimate for the tailings deposit is targeted for Fall 2026.
• WSP Canada Inc. has been retained to manage the program and subsequent resource estimate.

Evaluation of News Significance

• The news represents execution of a previously announced plan rather than new discovery or unexpected financial terms.
• The February 2026 release explicitly stated the goal was to "evaluate the grade, tonnage, and metallurgy of historic Kerr-Addison tailings... Goal is an initial mineral resource estimate."
• The May 19 announcement confirms the timeline (Fall 2026 for MRE) and methodology (Sonic drilling), which aligns with expectations set in prior months.
• No new strategic investors or financing terms were disclosed that would alter the capital structure immediately.
• While quantifying 40 million tonnes is significant, the economic viability depends on grade and recovery rates not yet confirmed by this specific news release.

Corporate Structure

• Stardust Metal Corp. operates primarily in the Kirkland Lake Gold Camp, Ontario.
• Key Projects: McGarry Project (Brownfield/Tailings), Omega Gold Project, Kirkland West Project.
• Location Advantage: Situated on the Larder Lake-Cadillac Break (LLCDZ), adjacent to major producers including Agnico Eagle, Barrick, and Pan American Silver.
