Glenstar Minerals Inc. reports exploration developments for polymetallic and critical-mineral properties, with recurring updates centered on its Wildhorse and Green Monster projects in Nevada. Company news covers trenching, reverse-circulation drilling, assay results, geological observations, mineralized zones, permitting with land-management agencies, contractor engagements and geophysical survey plans.
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 (GSTRF) received the final Green Monster seismic survey report, identifying low-velocity anomalies associated with its discovery zone in Nevada. Four survey lines covered a 150 × 300-meter area and provided continuous imaging to depths exceeding approximately 600 feet. Glenstar interprets the low-velocity features as prospective structural targets for follow-up drilling; the mapped anomaly extends between survey lines.
Previous drilling in May 2025 intersected mineralization at approximately 131–142 metres, with assays showing over 30% zinc and 5.7 oz/t silver, alongside nickel, cobalt and copper. The survey results are generally consistent with rock layers encountered during Phase 2 drilling, which comprised six holes totaling approximately 1,012 metres. Assays confirmed mineralization around discovery hole GMST-4. Next-stage drill targets are being selected using the seismic results.
Glenstar Minerals (GSTRF) reported polymetallic mineralization in all 10 holes drilled in its Phase 1 Wildhorse program in Nevada.
Four holes targeted the Coca Cola Zone and six the Rattlesnake Zone. Assays received so far show elevated silver, copper, lead and zinc over downhole intervals of approximately 50 to 100 feet, with narrower higher-grade intervals of approximately 5 to 25 feet. Five-foot samples include >1.0% zinc in CCZRC-3, 31.2 g/t silver in RTZRC-3 and 0.422% copper in CCZRC-1. The reported intervals are downhole lengths; true widths remain undetermined.
Results from 71 samples in RTZRC-6, gold assays for selected intervals in both zones and an overlimit zinc analysis for CCZRC-3 remain pending. Glenstar plans not to renew 28 peripheral claims it no longer considers priority areas; upon their expiry, the core Wildhorse property will comprise 61 claims covering approximately 1,220 acres.
Glenstar Minerals (CSE: GSTR, OTCQB: GSTRF, FSE: VO20) provided a detailed review of work completed at its Wildhorse Project in Mineral County, Nevada, following the Phase 1 reverse circulation drill program. Since June 2025, Glenstar has advanced from initial rock chip sampling and mapping to magnetic surveying, trenching, and drilling, and has submitted 860 drill samples for assay.
High‑grade surface assays, including 11.2 g/t gold, 11.35 g/t silver and copper up to 39%, led to multiple land expansions to 89 claims covering 720 hectares (1,780 acres). Trenching at the Coca Cola Zone defined an east‑west, metre‑scale quartz-vein and copper-oxide/sulfide zone, while Phase 1 drilling at the Coca Cola and Rattlesnake zones intersected visually encouraging oxide and sulfide alteration and quartz veinlet swarms consistent with Glenstar’s polymetallic mineralization model. Assay results from Paragon Geochemical are expected in early August and will guide the next phase of exploration.
Glenstar Minerals (OTCQB:GSTRF) completed a Terēan shear-wave seismic geophysical survey at its Green Monster project in Clark County, Nevada. The work produced four 2,400 ft cross sections to 600 ft depth, aimed at imaging cover thickness, bedrock, faults, voids and structural controls on mineralization.
The survey follows Phase 2 drilling, where six holes totaling ~3,320 ft intersected highly fractured, polymetallic but geologically complex zones. Early assays show significant mineralization but grades below expectations, prompting further geophysics. Historical sampling reported high copper, nickel, cobalt, zinc, silver and other metals.
Glenstar Minerals (OTCQB:GSTRF) is advancing two Nevada exploration projects, Green Monster and Wild Horse, focused on critical minerals linked to demand from defense, semiconductors, AI infrastructure, and domestic supply chains.
SmallCaps Daily interviewed CEO Dave Ryan and geologist Bob Marvin on recent work and next growth steps.
Glenstar (OTCQB:GSTRF) plans a Terēan shear-wave seismic survey at its Green Monster Project in Clark County, Nevada, starting June 29, 2026. Four 2,400 ft arrays will image geology to 600 ft depth, targeting faults, cover thickness, overburden, and depth to competent rock.
The survey follows a Phase 2 drill program of six holes totaling ~3,320 ft, which intersected polymetallic, highly fractured, clay-altered rock. Assays confirmed significant but complex mineralization, with grades currently below expectations, prompting further geophysical work.
Glenstar Minerals (OTCQB:GSTRF) reported a detailed update on its Green Monster Project in Clark County, Nevada, following Phase 1 and Phase 2 reverse circulation drilling.
Phase 1 confirmed high-grade polymetallic mineralization, Phase 2 expanded geological understanding, and the company is assessing advanced geophysical tools, including a potential Terean survey, to guide the next exploration phase.
Glenstar Minerals (OTCQB:GSTRF) submitted 860 drill samples from its reverse circulation program at the Wildhorse Project in Nevada for assay at Paragon Geochemical. Results are expected in 30–45 days. Glenstar also engaged Blossom Social for a one-year, CDN $26,000 investor outreach campaign.
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.
