GLENSTAR ENGAGES TEAM TO CONDUCT TRENCHING PROGRAM AT WILDHORSE PROJECT IN NEVADA

Glenstar Minerals Inc., further to its recent news release regarding permitting for the trenching program at Wildhorse (see news release dated Nov. 5, 2025), has engaged Merritt Construction Inc., of Mina, Nev., to conduct the trenching program that is currently scheduled to begin in early December.

The trenching program will be conducted on the Coca Cola zone at Wildhorse and is anticipated to comprise three parallel trenches, each measuring five feet wide and three feet deep, with each trench measuring approximately 50 feet in length and spaced 20 feet apart.

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 parts per million (ppm) 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 (m). 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).

According to Glenstar chief executive officer Dave Ryan, "We are quite happy and encouraged with the progress to date of the various exploration activities we have been able to conduct at Wildhorse thus far and very much look forward to getting our hands dirty with this upcoming trenching work."

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 in 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 (the 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 (g/t) gold, 1 per cent copper and 6,100 ppm 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).
