Glenstar stakes 28 claims at Wildhorse

Mr. David Ryan reports GLENSTAR REPORTS ADDITIONAL GOLD ASSAYS AND INCREASES LAND POSITION AT WILDHORSE PROJECT Additional gold assays from rock samples collected at the Coca Cola zone during phase 1 exploration work at Glenstar Minerals Inc.'s Wildhorse project in Mineral county, Nevada, continue to support the contention of an emerging copper-gold skarn target. Outcropping of high-grade copper plus gold at surface on the Coca Cola zone, when taken into consideration with all of the historical geologic data gathered to date, suggests that the property is underlain by a copper-gold porphyry system of unknown size. The presence of abundant magnetite plus epidote plus pyrite alteration encountered near the Coca Cola zone so far supports the evidence that this type of geology is a classic setting for copper porphyry systems. The mineralization found at surface to date is hosted in the Triassic age Excelsior formation, a complex unit of greenstones and metasedimentary rocks. This is of particular note as several large copper porphyry deposits of Jurassic age are well known, including the past-producing Yerington deposit located approximately 35 miles west of Wildhorse. The copper mineralization at Yerington is also hosted in the Excelsior formation. Copper-gold skarn systems are common above and around porphyry copper systems. The table below shows the assay results received from rock sampling that were previously reported, along with four new gold assays that were provided by ALS Chemex of Vancouver, B.C., Canada (see news releases dated July 23, 2025, and Sept. 3, 2025). At this early stage of exploration at Wildhorse, Glenstar has retained highly regarded economic geologist and porphyry copper expert Tom Borovicka to produce a detailed and comprehensive geologic base map of the property. The company is also in the final stages of permitting for a series of trenches to better expose the Coca Cola zone. It is anticipated that initial trenching will be composed of three parallel trenches, five feet wide and three feet deep, and each measuring 50 feet in length, spaced 20 feet apart. Additionally, an airborne drone magnetic survey is planned to cover the property in its entirety utilizing 50-metre spacing to better inform continuing exploration plans. The company also announces that it has staked a further 28 claims to the west, south and southeast of the Coca Cola and Highland zones. These increase the total land package to 89 claims, representing 1,780 acres (approximately 720 hectares). The focus of the phase 2 exploration program will be to greatly increase sample density and geologic information of the identified central zone. Property-scale zoning of gold, silver, tungsten, bismuth, tellurium and base metals suggests the centre of the mineralized system at Wildhorse lies around and between the Coca Cola and Rattlesnake 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 of strike length over these two zones of interest, and the geologic mapping will be an important addition to the current database to define the true extent of the skarn system and the expected underlying porphyry system. Project background and recent exploration work The Wildhorse property is composed 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 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, indicates 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 parts per million of antimony. It was also reported that outcropping zones also contain bismuth and tungsten grater than 200 parts per million, which points to a focused intrusive source for the epidote skarn alteration and polymetallic system. Several additional areas of exposed copper mineralization were located during the staking of the property. The geology of the area is complex, with strongly folded and faulted limestones, shale and metavolcanic rocks of Paleozoic age underlying the known mineralization and covering a large portion of the property claims. Importantly, an intrusive mass of rhyolite has intruded the deformed section in a position proximal to the known mineralization. Landslide rubble and boulder-bearing gravel units conceal the underlying geology in the north-central portion of the property (see news release dated May 8, 2025). The economic opportunity at Wildhorse points to the possible discovery of a large, well-mineralized skarn system under the surface workings and within the controlling north-south fault zone exposed at surface. Skarns are relatively easy to explore as they respond well to a variety of electric geophysical methods, including magnetic surveys. About Glenstar Minerals Inc.
