GLENSTAR BEGINS TRENCHING PROGRAM AT WILDHORSE PROJECT

Further to Glenstar Minerals Inc.'s news release regarding permitting for the trenching program at Wildhorse (see news release dated Nov. 5, 2025), the company has begun trenching work at its Wildhorse project in western Nevada. Glenstar previously announced that the trenching program was scheduled to begin in early December, however, due to unforeseen scheduling delays the work was not able to commence as anticipated. The company also announces that there has been a change of contractor for the trenching work. It was previously announced that Merritt Construction Inc. had been engaged to conduct the program (see news release of Nov. 19, 2025) but this engagement was cancelled. As a result, Glenstar has contracted Ranch Water Works, of Reno, Nev., to perform the trenching work that is currently under way.

The original trenching plan remains unchanged and will be conducted on the Coca Cola zone at Wildhorse which will be comprised of three parallel trenches; each measuring five feet wide and three feet deep, with each trench measuring about 50 feet in length and spaced 20 feet apart (see news release of Nov. 19, 2025).

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, B.C., 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 ppm (parts per million) 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 metres. 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).

Glenstar chief executive officer Dave Ryan stated: "Unfortunately we were unable to begin the Wildhorse trenching program in December, as was originally anticipated, due to unforeseen circumstances including a scheduling conflict with the company that was originally engaged for the work, as well as some concerns about conducting this work on site due to weather conditions. We are now in a position to begin this next stage of exploration at Wildhorse and are very optimistic about what it might uncover."

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 plus epidote plus 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 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 (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 (parts per million) 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)
