Glenstar Begins Geophysical Survey at Green Monster Project
Glenstar Minerals (OTCQB: GSTRF) has started a Hybrid-Source Audio-Magnetotellurics (HSAMT) geophysical survey at its Green Monster Project in southwestern Nevada on November 12, 2025. The field program is being run by Hasbrouck Geophysics and Advantage Geophysics over 13 lines with 50 metre station spacing and a 3-person field crew, and is expected to take ~two weeks.
Data will be processed into 2D/3D cross-sections and a rectangular cube; a technical report detailing methodology, processing and interpretation will follow. The property comprises 35 federal claims (~700 acres). Historical channel sampling returned 1.18 m of 3.77% Cu and 3.06% Ni (NI 43-101 report June 20, 2023).

Vancouver, British Columbia--(Newsfile Corp. - November 12, 2025) - Glenstar Minerals Inc. (CSE: GSTR) (OTCQB: GSTRF) (FSE: VO20) ("Glenstar" or the "Company") announces that it has commenced the previously announced Hybrid-Source Audio-Magnetotellurics Survey (the "HSAMT" or "Survey") at the Green Monster Project in southwestern Nevada. Hasbrouck Geophysics, Inc. ("Hasbrouck") of Prescott, Arizona and Advantage Geophysics, Inc. ("Advantage") of Phoenix, Arizona have mobilised to the site of the survey, and it is currently underway.
The survey data is being acquired at intervals of 50 metres along 13 lines and will be conducted by a 3-person field team from Advantage, in conjunction with Hasbrouck, and is expected to take approximately two weeks to complete in the field. The data collected will then be analysed and interpreted into a technical report that will be provided to the Company shortly thereafter.
The data will be processed using sophisticated software that will convert it into two- and three-dimensional cross-sections in depth and/or elevation formats. The complete data set will be interpolated into a rectangular cube and horizonal depth slices, referenced to the surface. The final report will detail the methodology, data acquisition, processing, modeling, and interpretation of the data (see news release dated October 29, 2025).
Project Background & Recent Exploration Work
The Green Monster Property is comprised of 35 federal lode claims covering ~700 acres located in Clark County, Nevada, on the west trending spur of the Spring Mountains and is approximately 40 miles southwest of Las Vegas. Until the recent drill program in May of 2025, no drilling was ever conducted on the property, but the Company's previous identification of robust nickel-copper with anomalous cobalt from sampling work done in 2022 indicated that several targets were ideal for shallow RC drilling (see news releases dated May 28, 2025, and July 16, 2025).
Glenstar acquired the Green Monster Property and conducted initial groundwork in 2022 that included reconnaissance geologic mapping, surface rock sampling, soil sampling, and a drone magnetic survey. Channel sampling across the exposed back of a raise off the main shaft returned 1.18 meters of
