Stardust Metal Uncovers Large, Never-Drilled Ultramafic Target Adjacent to High-Grade Kerr Addison in Kirkland Lake

Executive Summary

• Stardust Metal Corp. announced the discovery of a large, deep ultramafic‑type geophysical anomaly beneath its McGarry Project in the Kirkland Lake gold district.
• The Magnetotellurics (MT) survey shows the target from ~‑250 m to >‑1,000 m depth, beyond the reach of conventional IP methods, and is interpreted as a folded ultramafic unit with high‑grade gold potential.
• The company will conduct an Ambient Noise Tomography (ANT) seismic survey to refine the anomaly’s geometry before undertaking the first drill test.

Key Details

• Target Location: McGarry Project, adjacent to Kerr Addison, Macassa, Upper Beaver mines in Kirkland Lake district.
• Geophysical Findings:
• MT anomaly visible from ~‑250 m extending well beyond ‑1,000 m depth.
• IP survey corroborates surface‑level resistivity and chargeability patterns but does not detect the deep feature.
• Interpretation: An ultramafic unit in disconformable contact with overlying sediments, forming a west‑plunging syncline; low‑resistivity body suggests potential gold‑bearing ultramafic host similar to nearby deposits.
• Structural Context: Alignment with Larder Lake‑Cadillac Deformation Zone (LLCDZ), Armistice Fault, and Mill Zone Fault confirmed on both MT and IP datasets.
• Exploration Significance: Target has never been drilled; could host gold‑rich solutions analogous to Kerr Addison’s mineralization.
• Next Steps:
• Conduct Ambient Noise Tomography (ANT) survey for high‑resolution 3D imaging of density‑velocity contrasts.
• Use ANT results to define drill‑hole locations for the first test of the ultramafic target.
• Qualified Person Review: Technical information reviewed and approved by Charles Beaudry, M.Sc., P.Geo., Director of Stardust Metal Corp. (NI 43‑101).

“If it is an ultramafic unit as postulated, it has never been tested in drilling or seen in underground workings… the fluids responsible for the Kerr Addison deposit could have penetrated this domain.” – Charles Beaudry, Director, Stardust Metal Corp.
