Glenstar Receives Permit to Conduct Trenching Program at Wildhorse Project in Nevada

Rhea-AI Summary

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).

Positive

• BLM permit granted for initial trenching at Wildhorse
• High-grade grab samples: copper up to 5.3%
• Average silver of 21.6 ppm across four samples
• Property size: 1,780 acres (89 claims)

Negative

• Bedrock exposure minimal due to loose rock and soil cover
• Existing data limited to four grab samples across three meters

Vancouver, British Columbia--(Newsfile Corp. - November 5, 2025) - Glenstar Minerals Inc. (CSE: GSTR) (OTCQB: GSTRF) (FSE: VO20) ("Glenstar" or the "Company") announces that the Company has received a permit from the Bureau of Land Management ("BLM") to conduct an initial trenching program on its Wildhorse Project in Nevada. Trenching will be conducted on the Coca Cola Zone and is anticipated to be comprised of three parallel trenches; each measuring five feet wide and three feet deep, with each trench measuring ~50 feet in length and spaced 20 feet apart.

As previously reported, four grab samples were collected from the Coca Cola Zone, located in the west-central portion of the property, during the phase 1 exploration program at Wildhorse. These four samples, as reported by ALS Chemex in Vancouver, BC, returned copper values of 1.6%, 5.3%, 2.3% and 5.1%, along with an average of 21.6 ppm silver. Additionally, the samples are considered anomalous in bismuth - averaging 156 ppm across the four samples, and also tungsten - averaging 72.5 ppm across the same samples. These rock samples represent a rough transect across a prospect pit taken along a zone that is perpendicular to east-west vein and gossan orientations over a total width of three meters. Geologic observations of this sampled zone include the presence of a complex array of narrow porphyritic dikes with feldspar phenocrysts in a black, fine-grained matrix. Exposure of bedrock around the historic workings is minimal due to loose rock and soil cover (see news release dated July 23, 2025)

Outcropping of anomalous copper plus gold at surface on the Coca Cola Zone, when taken into consideration with all of the historical geologic data gathered to date, suggest that the property is underlain by a copper-gold porphyry system of unknown size. The presence of magnetite + epidote + pyrite alteration encountered at the Coca Cola Zone supports the contention that this type of geology is a classic setting for copper porphyry systems. Trenching at this zone will provide Genstar with further information as to the potential extent of mineralization encountered thus far.

Project Background & Recent Exploration Work

The Wildhorse Property is comprised of 89 mineral claims, representing 1,780 acres (720 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 1800's and early 1900's. 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, 1% copper, and 6,100 ppm of antimony. It was also reported that outcropping zones also contain bismuth and tungsten, which points to a focused intrusive source for the epidote skarn alteration and poly-metallic system (see news release dated February 11, 2025).
