GLENSTAR RECEIVES APPROVAL FOR EXTENSIVE DRILL PROGRAM AT WILDHORSE TUNGSTEN-COPPER-POLYMETALLIC PROJECT IN NEVADA

• 13 Hole Drill Plan on Two Exploration Sites
• 2,200 Feet of New Road Construction
• Driller Contracted

VANCOUVER, BC, April 1, 2026 /PRNewswire/ - Glenstar Minerals Inc. (CSE: GSTR) (OTCQB: GSTRF) (FRA: VO20) ("Glenstar" or the "Company") announces that it has received approval from the Bureau of Land Management ("BLM") to conduct a thirteen (13) hole reverse circulation drill program at it's Wildhorse Project in Mineral County, 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 the 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-Zinc that was reported from previous channel sampling results (see news release 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 be comprised of six (6) holes at the Coca Cola Zone and seven (7) 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 meter scale zone of quartz veining, and copper oxide and sulfide 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%, 5.3%, 2.3% and 5.1%, along with an average of 21.6 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 center 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 ~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 field work.

Property scale zoning of gold, silver, tungsten, bismuth, tellurium, and base metals suggest the center 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 suggests that there could be in excess of 1 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 September 24, 2025).

Project Geologist Bob Marvin remarked that, "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 & 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).
