Glenstar Receives Drill Permit for Phase 2 Program at Green Monster Project

Glenstar Minerals Inc. (CSE: GSTR) (OTCQB: GSTRF) (FSE: VO20) (‘Glenstar’ or the ‘Company’) announces that it has granted a permit by the Bureau of Land Management (the ‘BLM’) to conduct the Phase 2 drill program at its Green Monster Project in southwestern Nevada.

The permit allows the Company to drill nine (9) holes over four (4) locations on the property and will be comprised of approximately 300 metres of strike length exploration. As currently planned, Glenstar will collar two (2) holes in the area of the primary drilling undertaken in the Phase 1 drill program; three (3) holes will focus on the area that is considered the ‘discovery’ zone 150 metres to the west of the primary Phase 1 drill site, and two (2) holes each at two (2) sites will be situated further west along what is believed to be the mineralized east-west trending belt.

The precise location of each drill hole is yet to be determined and will be decided upon review of the data gleaned from the previously announced Hybrid-Source Audio-Magnetotellurics Survey (the ‘HSAMT‘ or ‘Survey‘) that was conducted by Hasbrouck Geophysics, Inc. (‘Hasbrouck‘) of Prescott, Arizona and Advantage Geophysics, Inc. (‘Advantage‘) of Phoenix Arizona. This survey has now concluded and the results, along with the various data sets, will be contained in a final report that will be provided to the Company by Hasbrouck. This report is expected to be completed in early December and the results will be instrumental in determining the best, and most advantageous, location for each hole of the Phase 2 drill program.

The survey data was acquired at intervals of 50 metres along 13 lines and was conducted by a 3-person field team from Advantage, in conjunction with Hasbrouck. The data collected is currently being analysed and interpreted 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) and will provide Glenstar’s geologic team with the information it needs to best determine the location of each drill hole in the Phase 2 program.

Glenstar CEO, Dave Ryan, stated, ‘The completion of the geophysical field work is an important milestone. Once we have the final report from Hasbrouck we will use this data to target sulfide facies mineralization in the area of the oxide mineralization that was intersected last summer.’

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 3.77% Cu (Copper), 3.06% Ni (Nickel), 0.21% Co (Cobalt) and 6.83% Zn (Zinc). These values are well in excess of select dump samples from historical underground workings and represent in-place, vein style mineralization. Sampling of oxide and sulfide bearing boulders directly downhill of the patented workings has confirmed the presence of very high zinc (>10%) and silver (>200ppm), as well as copper, uranium, and lead. (Sampling results provided above were previously published in the Green Monster Project NI 43-101 Technical Report dated June 20, 2023, Section 7.5).
