Glenstar Minerals (OTCQB: GSTRF) has commenced a Phase 2 reverse-circulation drill program at the Green Monster Project, Nevada, starting December 15, 2025. Alloy Drilling mobilized to drill nine holes across four target areas spanning ~300 metres of strike.
Phase 2 targets include two holes near the Phase 1 primary site, three holes at a 150 m distant “discovery zone,” and two holes each at two further western sites. Phase 1 assays reported a ~10 metre zone with zinc >30%, silver up to 177 ppm (5.7 oz/t), copper >0.36%, and anomalous nickel and cobalt; mineralization was intersected at ~131–142 metres.
Glenstar Minerals (OTCQB: GSTRF) hired Alloy Drilling to run a Phase 2 reverse-circulation (RC) drill program at the Green Monster Project, Nevada. The plan calls for nine holes across four locations covering ~300 metres of strike; Alloy will mobilize in mid-December and the program is expected to finish before the Christmas holiday.
Drill locations will be finalized after receipt of a Hybrid-Source AMT (HSAMT) report from Hasbrouck Geophysics based on a mid-November survey. The company also extended its Altura Media engagement for CDN$250,000 for marketing and investor awareness services. The Green Monster property comprises ~35 federal claims (~700 acres); prior channel sampling returned 1.18 m of 3.77% Cu, 3.06% Ni, 0.21% Co, 6.83% Zn.
Glenstar Minerals (OTCQB:GSTRF) will attend the American Exploration & Mining Association annual meeting in Sparks, Nevada, December 7–12, 2025, and staff will staff Booth #13 in the core shack area.
Company executives and project geologist Robert Marvin will present updates on the Green Monster and Wildhorse projects, share geological data from the past eight months, and be available to discuss recent sampling and the May 2025 drill program at Green Monster.
Glenstar Minerals (OTCQB: GSTRF) received a BLM drill permit for a Phase 2 program at the Green Monster Project in southwestern Nevada on November 24, 2025.
The permit authorizes nine holes across four sites covering ~300 metres of strike. A recently completed HSAMT geophysical survey (13 lines at 50m intervals) will be interpreted into 2D/3D models; Hasbrouck's final report is expected in early December 2025 and will guide exact collar locations. Glenstar plans to target sulfide facies near oxide mineralization intersected in 2025.
Project facts: 35 federal lode claims (~700 acres), ~40 miles southwest of Las Vegas; historical channel sample: 1.18 m of 3.77% Cu, 3.06% Ni, 0.21% Co, 6.83% Zn (NI 43-101 report, June 20, 2023).
Glenstar Minerals (OTCQB: GSTRF) has engaged Merritt Construction to conduct a trenching program at the Wildhorse project in Mineral County, Nevada, scheduled to begin in early December (announcement dated November 19, 2025).
The program targets the Coca Cola Zone with three parallel trenches (~5 ft wide, 3 ft deep, ~50 ft long, spaced 20 ft). Prior phase 1 grab samples returned copper of 1.6%, 5.3%, 2.3%, 5.1%, average 21.6 ppm silver, 156 ppm bismuth, and 72.5 ppm tungsten.
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).
Glenstar Minerals (OTCQB: GSTRF) received a Bureau of Land Management permit on Nov 5, 2025 to conduct an initial trenching program at its Wildhorse Project in Mineral County, Nevada.
The program targets the Coca Cola Zone and will consist of three parallel trenches ~50 feet long, 5 feet wide and 3 feet deep, spaced 20 feet apart. Previous Phase 1 grab samples returned copper values of 1.6%, 5.3%, 2.3% and 5.1%, average silver 21.6 ppm, average bismuth 156 ppm and average tungsten 72.5 ppm. The property comprises 89 claims (1,780 acres).
Glenstar Minerals (OTCQB: GSTRF) has engaged Hasbrouck Geophysics to run a Hybrid-Source Audio-Magnetotellurics (HSAMT) survey at the Green Monster Project in southwestern Nevada.
Survey acquisition will run on 13 lines at 50‑metre intervals, executed by a 3‑person Advantage Geophysics field team under Jim Hasbrouck's design and supervision. Data will be processed into 2D/3D cross‑sections and a rectangular data cube. Field work is slated to begin in early November 2025.
Background: the 700‑acre property produced channel sample results of 1.18 m: 3.77% Cu, 3.06% Ni, 0.21% Co, 6.83% Zn, and surface boulders with >10% Zn and >200 ppm Ag; sampling results are referenced to a June 20, 2023 NI 43‑101 report.
Glenstar Minerals (OTCQB: GSTRF) has retained MWH Geo-Surveys to begin a UAV magnetic survey over ~10.5 km2 of the Wildhorse Project in Mineral County, Nevada, starting immediately on October 23, 2025.
The Wildhorse property comprises 89 claims (1,780 acres / 720 hectares). Historical and recent field work identified outcropping high-grade copper and gold, including a quartz veinlet with >1 g/t Au, 1% Cu and 6,100 ppm Sb, plus bismuth and tungsten >200 ppm, supporting a possible copper-gold porphyry and skarn system. The survey aims to map magnetite-bearing alteration and identify targets for follow-up exploration.
Glenstar Minerals (OTCQB: GSTRF) has reported additional gold assays from its Wildhorse Project in Nevada, reinforcing evidence of a copper-gold skarn target. The company's Phase 1 exploration at the Coca Cola Zone revealed significant gold assays ranging from 2.18 to 11.2 g/t and copper values up to 5.29%.
The company has expanded its land position by staking 28 additional claims, bringing the total to 89 claims covering 1,780 acres. The geological setting, featuring magnetite + epidote + pyrite alteration, suggests potential for a copper-gold porphyry system. Glenstar has hired expert geologist Tom Borovicka and plans trenching activities and an airborne drone magnetic survey to advance exploration efforts.
