Glenstar receives BLM OK for Wildhorse drill program

Mr. David Ryan reports GLENSTAR RECEIVES APPROVAL FOR EXTENSIVE DRILL PROGRAM AT WILDHORSE TUNGSTEN-COPPER-POLYMETALLIC PROJECT IN NEVADA Glenstar Minerals Inc. has received approval from the Bureau of Land Management (BLM) to conduct a 13-hole reverse circulation (RC) drill program at its Wildhorse project in Mineral county in Nevada. The BLM approval also provides for the construction of 2,200 feet of additional access road(s) to the drill sites, to complement existing land access to the exploration areas and planned drill target sites. The company has also contracted Midnight Sun Drilling Inc. (MSD) to conduct the drill program at Wildhorse. MSD is a well-established drilling company in business for over 50 years, with offices in Yukon, Alaska and Nevada, that has previously worked with Glenstar on the Green Monster project in southern Nevada in May of 2025, which confirmed the presence of anomalous nickel, copper, cobalt and zinc, reported from previous channel sampling results (see news releases dated April 22, 2025, and May 28, 2025). Assay results from the recent trenching program at Wildhorse that was conducted in late February are still pending from ALS Chemex, however, visual examination of the bedrock that was uncovered in the trenches during this program confirmed what previous surface sampling suggested was occurring geologically at Wildhorse. The company anticipates receiving these assay results at any time (see news release dated March 10, 2026). The Wildhorse project drill plan will comprise 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, which 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 throughout the exposed bedrock was significant and is considered to be very encouraging. 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 (ppm) 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 one 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 tungsten, bismuth and antimony 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 mineralization direction encountered during previous fieldwork. Property-scale zoning of gold, silver, tungsten, bismuth, tellurium and base metals suggest 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 (km) 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 geologist Bob Marvin remarked: "We are quite pleased with the quick turnaround from the BLM in approving the drill program and new road access construction. The addition of Midnight Sun Drilling to the project is fantastic as we have worked very successfully with them at the Green Monster project. Personally, I am quite excited to kick off this next stage of exploration drilling to see how significant the extent of polymetallic mineralization and tungsten in particular, at Wildhorse truly is." Project background and recent exploration work The Wildhorse property comprises 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 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 one gram per tonne gold, 1 per cent 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 polymetallic system (see news release dated Feb. 11, 2025).
