Glenstar to conduct geophysical survey at Green Monster

Executive Summary

• Glenstar Minerals Inc. has retained Hasbrouck Geophysics Inc. to conduct a hybrid-source audio-magnetotellurics (HSAMT) survey at its Green Monster project in southwestern Nevada.
• The survey aims to better understand the geophysical structure of a polymetallic zone discovered during a recent Phase 1 drill program, with data to be used for prioritizing Phase 2 drilling.
• Fieldwork is scheduled to begin in early November, with Hasbrouck responsible for design, supervision, processing, and final interpretation.

Key Details

• Survey Type: Hybrid-source audio-magnetotellurics (HSAMT).
• Service Provider: Hasbrouck Geophysics Inc. (Prescott, Ariz.) retained to design, supervise, process, model, and interpret data; Advantage Geophysics Inc. (Phoenix, Ariz.) providing the three-person field team.
• Survey Scope: Data acquisition at 50-meter intervals along 13 lines.
• Data Processing: Sophisticated software to convert data into 2D and 3D cross-sections (depth/elevation), interpolated into a rectangular cube and horizontal depth slices referenced to the surface.
• Timeline: Fieldwork slated to begin in early November.
• Strategic Purpose: The survey will provide key information on the geophysical structure of the polymetallic zone discovered in Phase 1 drilling, aiding in the planning of Phase 2 drill program priorities.
• Project Location: Green Monster property, comprising 35 federal lode claims covering approximately 700 acres in Clark County, Nevada, on the west-trending spur of the Spring Mountains, approximately 40 miles southwest of Las Vegas.
• Historical Context: No drilling had been conducted on the property until a program in May 2025. Previous sampling in 2022 identified robust nickel-copper with anomalous cobalt.
• Previous Sampling Results (Channel Sampling):
  • 1.18 meters of 3.77% Copper (Cu).
  • 3.06% Nickel (Ni).
  • 0.21% Cobalt (Co).
  • 6.83% Zinc (Zn).
• Previous Sampling Results (Boulder Sampling):
  • Zinc: >10%.
  • Silver: >200 ppm.
  • Also confirmed presence of copper, uranium, and lead.
• Qualified Person: Robert Marvin, PGeo (Ontario), independent consulting geologist who has overseen and approved the technical information.

Notable Quotes

• Dave Ryan, CEO: "The HSAMT survey will provide key information and give us a much better understanding of the geophysical structure of the polymetallic zone discovered during the recent phase 1 drill program and will be an invaluable aid to us in planning the priorities for the phase 2 drill program."
