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.
Glenstar Minerals (OTCQB: GSTRF) provided a comprehensive update on its two key mining projects in Nevada and corporate developments. At the Green Monster project, drilling revealed significant polymetallic mineralization including >30% zinc, 177 ppm silver, and >0.36% copper. The company plans Phase 2 drilling with eight holes totaling 2,000 feet.
At the Wildhorse project, Phase 1 exploration yielded impressive results including samples with up to 11.2 g/t gold, 11.35 g/t silver, and copper values reaching 5.3%. The company expanded its land position to 61 claims covering 1,220 acres.
Corporately, Glenstar successfully raised $3.48 million through a private placement and expanded its market presence by listing on the OTCQB and Tradegate Exchange.
Glenstar Minerals (OTCQB: GSTRF) has announced significant assay results from its Wildhorse property in Nevada. Stream sediment sampling revealed strong tungsten-bismuth anomalies across four distinct drainages, with a notable gold sample yielding 11.2 g/t gold and 11.35 g/t silver.
The results confirm previously known mineralized zones and identify two additional prospective drainages, effectively expanding the Rattlesnake Zone. The findings support an intrusive-center geological model at the property's Palomino Hill, which shows classic metal zoning patterns similar to nearby Nevada mining districts.
The Wildhorse Property, spanning 1,220 acres with 61 mineral claims, shows potential for a large skarn system with historical workings dating back to the 1800s. The property's geology includes folded and faulted limestones, shale, and metavolcanic rocks, with an intrusive rhyolite mass proximal to known mineralization.
Glenstar Minerals (OTCQB: GSTRF) has responded positively to the U.S. government's announcement of establishing its first Strategic Minerals Reserve at the Hawthorne Army Depot in Nevada. The initiative, backed by a $2 billion allocation from the $52.7 billion CHIPS Act, aims to create a hub for storing, refining, and distributing critical minerals.
The company recently raised C$3 million through private placement to advance drilling at its Green Monster and Wildhorse projects in Nevada. Green Monster has shown promising polymetallic results including grades exceeding 30% zinc, 5.7 oz./t silver, plus cobalt and nickel. Wildhorse sampling has revealed grades up to 5.3% copper and 21.6 ppm silver.
Glenstar Minerals (OTCQB: GSTRF) has announced significant findings at its Green Monster Project in Nevada, following its May 2025 drill program. A new polymetallic zone was discovered in hole GMST-4, located 150 metres away from the main target zone. The newly found mineralization, approximately 10 metres wide, contains exceptional mineral grades including >30% zinc, 177 ppm silver, 523 ppm nickel, 91.9 ppm cobalt, and >0.36% copper.
The discovery was made at depths between 131-142 metres in the hanging wall of the Green Monster Fault Zone. This finding has prompted Glenstar to shift its exploration focus, with Phase 2 drilling now planned to expand the new zone. The Green Monster Property, comprising 35 federal lode claims covering ~700 acres, is part of a larger 30-kilometer fault zone known for zinc mineralization with anomalous nickel, cobalt, and copper occurrences.
