Glenstar Reports Broad Polymetallic Mineralization at Wildhorse Project; Gold Assays Pending
Pending assays leave the drill results incomplete, while Glenstar plans to let peripheral Wildhorse claims expire.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Summary
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.

Vancouver, British Columbia--(Newsfile Corp. - September 29, 2026) - Glenstar Minerals Inc. (CSE: GSTR) (OTCQB: GSTRF) (FSE: VO20) ("Glenstar" or the "Company") announces that the assay results from the Phase 1 drill program at the Wildhorse Project in Nevada are being carefully evaluated in relation to the high-grade zones exposed at surface at both the Coca Cola Zone and Rattlesnake Zone on the property.
Polymetallic mineralization is present in all completed holes of the Phase 1 program, which comprised 10 holes, including four at the Coca Cola Zone and six at the Rattlesnake Zone (see news release dated May 13, 2026, and April 14, 2026). Hole #RTZRC-6 at the Rattlesnake Zone, which accounts for 71 samples, are still being assayed and results will be available once they are completed and evaluated. Additionally, the Company is also awaiting overlimit analysis on the sample of >
The assays received thus far shows that Mineralization occurs over downhole intervals of approximately 50 to 100 feet, containing elevated silver, copper, lead and zinc values, as well as within narrower higher-grade downhole intervals of approximately 5 to 25 feet. Gold assays are pending for selected intervals from both the Coca Cola and Rattlesnake Zones. Reported intervals represent downhole lengths, and true widths have not yet been determined.
Highlights include the following samples which represent 5 foot down hole intervals:
>
1.0% Zn in Coca Cola hole CCZRC-331.2 g/t Ag in Rattlesnake hole RTZRC-3
0.422% Cu in Coca Cola hole CCZRC-10.171% Cu in Rattlesnake hole RTZRC-512.5 g/t Ag in Rattlesnake hole RTZRC-4
All mineralized intervals in both drill areas are associated with intense iron oxide flooding of the host rocks. Detailed examination of logged geology versus assay results is ongoing. Locally abundant sulfides including pyrite, chalcopyrite and sphalerite remain in both drill areas resulting from incomplete oxidation of the original polymetallic sulfide mineralization.
Bob Marvin, Project Manager and Geologist, noted that, "Mineralization in both the Coca Cola and Rattlesnake Zones occurs within two principal downhole intervals, with the position of these intervals showing consistent continuity from hole to hole in both drill areas. Additional work is required to better understand the significance and extent of this apparent continuity. Further interpretation of the mineralized system will also incorporate the pending assays from RTZRC-6 along with gold assays from selected intervals."
The Company also announces that it will not renew the 28 peripheral claims staked to the west, south and southeast of the Coca Cola and Highland Zones in September 2025 (see news release dated September 24, 2025). Those claims were added to the Company's existing 61-claim Wildhorse land package, increasing the property at that time to 89 claims. Following the trenching and drilling programs completed at Coca Cola, the Company determined that the 28 additional claims are no longer considered priority areas for ongoing expansion exploration. Upon expiry of those claims, the core Wildhorse Property will continue to comprise 61 mineral claims covering approximately 1,220 acres (494 hectares) in Mineral County, Nevada.
Project Background
The Wildhorse Property is comprised of 61 mineral claims, representing 1,220 acres (494 hectares) in Mineral County, Nevada, and was initially targeted after compilation of all available data, including notes of a 1975 field examination contained in the Anaconda Company archives housed at the University of Wyoming. The claims show historical workings that appear to date from the late 1800s and early 1900s. Other claim stakes that the geological team discovered on the property indicate the last time the area was staked was 2011, however, these claims were never registered with the BLM. Preliminary geological assessment of the claims, and the area in general, indicate there are a series of east dipping mineralized zones. Initial field examination of the property identified and sampled a quartz veinlet zone containing in excess of 1 gram per ton gold,
Sampling, Analytical and Quality Assurance/Quality Control
A total of 860 samples from the Company's Phase 1 reverse circulation drill program at the Wildhorse Project were submitted to Paragon Geochemical Inc. in Sparks, Nevada, an independent commercial analytical laboratory, for sample preparation and analysis. Samples were collected, identified, securely bagged and transported to the laboratory under the supervision of Company geological personnel. At the laboratory, samples were dried, crushed, and pulverized prior to analysis. Silver, copper, lead, zinc and other elements were analyzed using a multi-element four-acid digestion followed by ICP-OES/ICP-MS analysis. Gold analyses for selected intervals are being completed separately by fire assay. Laboratory QA/QC procedures include internal standards, blanks and duplicate analyses. QA/QC results were reviewed prior to the release of the analytical results reported herein and were considered acceptable.
