The company also reports market-awareness activities and trading references for its CSE, OTCQB and Frankfurt-listed shares.
Glenstar (OTCQB:GSTRF) received BLM approval on April 1, 2026 to drill 13 reverse‑circulation holes at the Wildhorse tungsten‑copper‑polymetallic project in Mineral County, Nevada, and to build 2,200 feet of access road.
The program contracts Midnight Sun Drilling and targets Coca Cola (6 holes, up to 500 ft) and Rattlesnake (7 holes, 300–500 ft) zones; trench assays are pending.
Glenstar Minerals (OTCQB: GSTRF) submitted a BLM permit application on March 17, 2026 to drill a 13-hole reverse-circulation program at the Wildhorse Project, Mineral County, Nevada.
The plan targets six holes at the Coca Cola Zone and seven at Rattlesnake Zone, testing up to 500-foot depths and a potential >1 km strike between zones.
Glenstar Minerals (OTCQB: GSTRF) completed trenching at the Coca Cola Zone, Wildhorse Project, Nevada, defining a meter-scale quartz vein and copper oxide/sulfide zone traced for 15 meters strike and exposing wider-than-expected alteration.
Four historical grab samples returned copper up to 5.3% and average silver 21.6 ppm. Fourteen chip samples were dispatched to ALS Chemex on Feb 28, 2026. The company engaged Spark Newswire for investor outreach with an initial marketing budget of up to USD $100,000.
Glenstar (OTCQB: GSTRF) has begun a trenching program at its Wildhorse project in western Nevada after permitting and scheduling delays. Work targets the Coca Cola Zone with three parallel trenches (~5 ft wide, 3 ft deep, ~50 ft long, 20 ft spacing). Prior ALS assays returned copper of 1.6%, 2.3%, 5.1% and 5.3% and average silver of 21.6 ppm, plus anomalous bismuth and tungsten. The company changed contractors and expects trenching to better define near-surface porphyry-style mineralization.
Glenstar (OTCQB: GSTRF) completed its Phase 2 drill program at the Green Monster Project, Nevada, comprising six RC holes totalling 3,320 feet from three drill pads.
Preliminary visual logging found 3 of 6 holes with abundant fracturing, clay alteration and orange-red oxides; samples were sent to ALS Vancouver for assay. Phase 1 previously returned a very high-grade zinc occurrence reported at >30% Zn and significant silver, nickel, cobalt and copper intercepts around 131–142 m depth.
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.
