ASSAY RESULTS REPORT HIGH GRADE GOLD ENCOUNTERED IN COCA COLA ZONE TRENCHING PROGRAM AT WILDHORSE PROJECT; PHASE 1 DRILLING BEGINS

Glenstar Minerals Inc. has received assay results from the trenching work undertaken at the Wildhorse project in Mineral county, Nevada, in late February, and the phase 1 drill program has begun.

Coca Cola trenching

Assay results from trench No. 1 at the Coca Cola zone show that high-grade gold, with one sample measuring 23.6 grams per tonne (g/t), was discovered in deep red oxidized material contained within a structural zone trending east-west. This trend of red oxidation has been traced uphill in a linear belt that is at least 100 metres in strike length. The exact nature of the host rock of the oxide mineralization has not been confirmed as yet, however, this gold-rich style and mapped trend of mineralization is a focus of the phase 1 drilling plan at the Coca Cola zone.

Also reported was an average of approximately 1 per cent copper within the same deep red oxidized structure containing the gold results and is deemed to be of considerable interest. Assay results from samples taken from trench No. 2, which is lower down the incline from trench No. 1, proved to be unremarkable and suggests that the trend may end at its location or that it dips dramatically vertical. This information is beneficially relevant to the plan of drill placement, which will follow the trend to the east of the trenches.

Wildhorse drill program commences

Midnight Sun Drilling Inc. (MSD) mobilized to the property late last week and reverse circulation drilling began over the weekend. Six drill sites were permitted for the Coca Cola zone, which will test the east-west trend discovered in the trenching program. Each drill site is anticipated to accommodate an initial hole that is planned to be drilled to a depth of up to approximately 500 feet. However, the number of holes drilled at each site could be increased in order to follow mineralization that may be encountered and observed at various depths downhole. Any additional holes at each site would be drilled at different angles from surface to help determine the possible extent and trend of mineralization that may be encountered.

Seven drill sites are permitted for the Rattlesnake zone, which lies approximately 1,600 feet to the northeast of the Coca Cola zone, and each site is planned to be drilled to a depth of 300 to 500 feet. The initial holes at each site at Rattlesnake are planned to be vertical and will follow the north-south mineralization direction encountered during previous fieldwork. As with the Coca Cola zone, however, additional holes could be drilled at each site at varying angles to follow and test any observable mineralization. The Rattlesnake zone is centred on historical workings and dump samplings that have returned results of more than 100 g/t silver along with one g/t gold, 3 per cent copper, 0.59 per cent antimony and 256 parts per million (ppm_ tungsten. The Rattlesnake zone strikes north-south and dips approximately 20 degrees to the east, and the company is targeting the downdip continuation to the east of the historically worked exposures.

Initial drilling has begun at the Coca Cola zone and, once completed, will then move to the Rattlesnake zone. The entire drill program at the Wildhorse project is expected to take approximately 21 days.

Project geologist Bob Marvin stated: "The data compiled thus far from the two zones at Wildhorse suggest that we have two different systems: Coca Cola, trending east-west, with gold and copper being prevalent, and Rattlesnake trending north-south, which has presented very encouraging tungsten and antimony numbers from sampling along with high silver and copper. This could represent an ideal polymetallic target that is pretty robust and definitely meter scale."

Project background

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 (Bureau of Land Management). 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 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 points to a focused intrusive source for the epidote skarn alteration and polymetallic system (see news release dated Feb. 11, 2025).
