Stardust Metal discovers target at McGarry

Executive Summary

• Stardust Metal Corp. has identified a significant, never-drilled geophysical target at its McGarry project, located in the Kirkland Lake gold district adjacent to the high-grade Kerr Addison mine.
• A combined magnetotellurics (MT) and induced polarization (IP) survey revealed a large, deep anomaly beneath the sedimentary cover, interpreted as a folded ultramafic unit extending from approximately 250 meters to beyond 1,000 meters depth.
• The company plans to conduct an ambient noise tomography (ANT) seismic survey to refine the target's geometry in preparation for the first-ever drill testing of this high-priority zone.

Key Details

• Project Location: McGarry project, Kirkland Lake gold district, Ontario.
• Geophysical Survey: Comprehensive IP-MT survey completed by Quantec and interpreted by Charles Beaudry, MSc, PGeo.
• MT Anomaly Characteristics:
  • Large, deep feature beneath sedimentary cover.
  • Visible from approximately -250 meters extending well beyond -1,000 meters (below the detection limit of conventional IP methods).
  • Identified as a low-resistivity body sitting beneath the sediments.
• IP Survey Results:
  • Confirmed general patterns of MT results in the top 250 meters.
  • Major structures visible on both surveys, including the Larder Lake-Cadillac deformation zone (LLCDZ), Armistice fault, and Mill zone fault.
  • The specific anomaly highlighted is located below the IP response.
• Geological Interpretation:
  • Anomaly interpreted as a folded ultramafic unit in disconformable contact with overlying sediments.
  • Forms a synclinal structure plunging to the west.
  • Base of the sedimentary unit has not been intersected in drilling.
  • Shape and response suggest potential to host an ultramafic unit similar to rocks hosting known gold deposits in the district.
• Structural Context:
  • Key district-scale controls on mineralization (LLCDZ, Armistice fault, Mill zone fault) are clearly reflected in both IP and MT datasets.
  • Significant near-surface gold mineralization exists as much as 1,000 meters south of the LLCDZ.
• Next Steps:
  • Conduct an ambient noise tomography (ANT) seismic survey.
  • Goal: Provide high-resolution 3-D imaging of density-velocity contrasts to refine depth, size, and geometry.
  • Objective: Guide the first-ever drill testing of the ultramafic target.

Notable Quotes

• "If it is an ultramafic unit as postulated, it has never been tested in drilling or seen in underground workings and it is possible that the fluids responsible for the Kerr Addison deposit... could have penetrated the domain lying beneath the sedimentary unit. This prediction is totally reasonable because of the presence of significant near-surface gold mineralization... as much as 1,000 metres south of the Larder Lake-Cadillac deformation zone (LLCDZ)," said Charles Beaudry, director of Stardust.
