Updates commonly reference the Coca Cola and Rattlesnake zones at Wildhorse, copper oxide and sulfide mineralization, gold assays, tungsten-copper-polymetallic targets and Green Monster drilling results involving fractured and altered rock. The company also reports market-awareness activities and trading references for its CSE, OTCQB and Frankfurt-listed shares.
Glenstar Minerals (OTCQB:GSTRF) completed Phase 1 reverse circulation drilling at the Wildhorse Project in Nevada, finishing six holes at the Rattlesnake Zone and four at the Coca Cola Zone.
The program was expanded from 3,500 to 4,300 feet, with drilling intersecting altered, quartz-veined, polymetallic mineralization at surface and depths of 100–150 meters.
Glenstar Minerals (OTCQB: GSTRF) reports Phase 1 reverse-circulation drilling is underway at the Wildhorse Project, Mineral County, Nevada, focused on the Rattlesnake Zone. Early holes at Coca Cola and Rattlesnake returned multi-meter oxide and sulfide alteration; RTSRC-1 hit mineralization from surface to 345 feet, with sulfide to 385 feet.
Drilling continues; samples will be shipped to Paragon Geochemical in Sparks, Nevada, for assay. True widths are not yet determined.
Glenstar Minerals (OTCQB: GSTRF) reported Phase 2 drilling results at the Green Monster Project (Nevada) showing widespread polymetallic mineralization across six holes (~3,320 feet total) but with grades lower than expected.
The company plans a Terean geophysical survey to map faults, depth to competent rock, overburden, paleochannels and fractured zones to refine targeting for follow-up work.
Glenstar Minerals (OTCQB: GSTRF) reported trench assays at the Wildhorse Project showing a high‑grade gold sample of 23.6 g/t in deep red oxidized material at the Coca Cola Zone and an average of ~1% copper in the same structure. Phase 1 reverse‑circulation drilling has started: six drill sites at Coca Cola (~500 ft planned) and seven sites at Rattlesnake (300–500 ft planned). Historic Rattlesnake sampling includes >100 g/t silver, 1 g/t gold, 3% copper, 0.59% antimony and 256 ppm tungsten. The program is expected to take ~21 days.
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.
