GLENSTAR MINERALS SUBMITS PERMIT APPLICATION FOR EXTENSIVE DRILL PROGRAM AT WILDHORSE PROJECT IN NEVADA

Glenstar Minerals Inc. has submitted an application to the Bureau of Land Management to conduct a 13-hole reverse circulation drill program at its Wildhorse project in Mineral county, Nevada. The drill plan will be composed of six holes at the Coca Cola zone and seven holes at the Rattlesnake zone. The company is very enthusiastic to initiate drilling at both of these zones at Wildhorse following the recent trenching that occurred at the Coca Cola zone that resulted in defining the bedrock orientation of a metre-scale zone of quartz veining and copper oxide and sulphide mineralization. Trenching also exposed a wider width of alteration than initially anticipated, and the trend of mineralization that continued eastward is seen as oxide minerals on fracture trending due east and uphill from the trenched area.

Coca Cola zone

The six planned drill holes at the Coca Cola zone will follow the mineralized trend that was uncovered during previous sampling work conducted to the east of the trenches, where select assay results returned copper values of 1.6 per cent, 5.3 per cent, 2.3 per cent and 5.1 per cent, along with an average of 21.6 parts per million silver. Additionally, the samples are anomalous in bismuth -- averaging 156 ppm across four samples, and also tungsten -- which averaged 72.5 ppm across the same samples. Geologic observations of this zone include the presence of a complex array of narrow porphyritic dikes with feldspar phenocrysts in a black, fine-grained matrix.

By compiling the results of the phase 1 rock sampling work and geologic observations from the trenching program, a clear picture of property-scale geological, alteration and mineralization zoning is emerging. The central portion of the property contains complex porphyritic intrusions within a strong skarnified envelope. High-grade copper and silver, along with strongly anomalous bismuth, antimony and tungsten in the central portion, are surrounded by strong zinc and lead mineralization in areas more distal from the centre of the system as it is understood at this early stage of exploration of the property (see news release of July 23, 2025).

Trenching also showed that what was originally thought to be a north-south trend of mineralization was intersected by the newly uncovered east-west trend of highly fractured and altered rock that appears to continue beyond the trenches. This new trending information has confirmed the drill hole locations for this first phase of drilling at the Coca Cola zone. The six-hole drill plan will follow the mineralized trend line for approximately 500 feet from the east sampling zone to the west trench area, and each hole will be drilled to a depth of up to 500 feet at various angles yet to be fully determined.

Rattlesnake zone

The seven drill holes planned for the Rattlesnake zone, which lies approximately 1,600 feet to the northeast of the Coca Cola zone, will each be drilled to a depth of 300 to 500 feet; however, these holes will be vertical in nature and follow the north-south-striking, shallowly east-dipping mineralization encountered during previous fieldwork at historic workings located where the shallowly dipping mineralized zone is exposed at surface.

Property-scale zoning of gold, silver, tungsten, bismuth, tellurium and base metals suggests the centre of the mineralized system at the Wildhorse project lies around and between the Rattlesnake and Coca Cola zones, and may extend under cover to the east and west of these outcropping areas. Data compiled thus far suggest that there could be in excess of one kilometre of strike length between these two zones and the drill plan is designed to test the degree and extent of similar mineralization at each zone and delineate the magnitude of the potential skarn system and the expected underlying porphyry system (see news release of Sept. 24, 2025).

Project background and recent exploration work

The Wildhorse property is composed 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 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 Bureau of Land Management. Preliminary geological assessment of the claims, and the area in general, indicates there is a series of east-dipping mineralized zones. Initial field examination of the property identified and sampled a quartz veinlet zone containing in excess of one gram per ton gold, 1 per cent copper and 6,100 ppm of antimony. It was also reported that outcropping zones also contain bismuth and tungsten, which point to a focused intrusive source for the epidote skarn alteration and polymetallic system (see news release dated Feb. 11, 2025).
