Glenstar Minerals hires MWH for UAV survey at Wildhorse

Mr. David Ryan reports GLENSTAR BEGINS UAV MAGNETIC SURVEY AT WILDHORSE PROJECT Glenstar Minerals Inc. has retained MWH Geo-Surveys International Inc. of Reno, Nev., to conduct a UAV (unmanned aerial vehicle) magnetic survey on the company's Wildhorse project in Mineral county, Nevada. The total survey area size is approximately 10.5 square kilometres and will begin immediately. This magnetic survey is an important component of continuing exploration activities on the property where outcropping of high-grade copper plus gold at surface suggest 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 of the property supports the evidence that this type of geology is a classic setting for copper porphyry systems (see news release dated Sept. 24, 2025). Glenstar chief executive officer Dave Ryan stated that, "This magnetic survey will provide us with critical data that will aid us in our ongoing exploration efforts, and will hopefully identify additional key areas that should be further evaluated." 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 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 parts per million of antimony. It was also reported that outcropping zones also contain bismuth and tungsten greater 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 underlie the known mineralization and cover 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. Land slide rubble and boulder-bearing gravel units conceal the underlying geology in the northcentral 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.
