Vancouver, British Columbia--(Newsfile Corp. - May 8, 2025) - Glenstar Minerals Inc. (CSE: GSTR) (OTCQB: GSTRF) (FSE: VO2) ("Glenstar" or the "Company") announces that it has staked 45 mineral claims, representing 900 acres (364 hectares) in Mineral County, Nevada. Mineral County lies approximately 100 miles south of Lake Tahoe and its western boundary abuts the California state border.

The area was 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, known as the Wildhorse Claims, show historical workings that appear to date from the late 1800's and early 1900's. 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, 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 1 gram per ton gold, 1% copper, and 6,100 ppm of antimony. It was also reported that outcropping zones also contain bismuth and tungsten >200 ppm, which points to a focused intrusive source for the epidote skarn alteration and poly-metallic system.

Several additional areas of exposed copper mineralization were located during the staking of the property. These new zones have not been sampled yet but clearly show that multiple targets for detailed exploration exist on the property.

The geology of the area is complex, with strongly folded and faulted limestones, shale, and metavolcanic rocks of Paleozoic age underly 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.

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 variety of electric geophysical methods including magnetic surveys.

The work program at Wildhorse will begin with a detailed dry stream bed sediment sampling program to explore for additional mineralization on the property. Geologic mapping and detailed rock chip sampling will follow, and then a more extensive work program, following positive results, will be required to conduct a comprehensive geophysical survey. Once completed, the geophysical survey will define possible drill targets.

Glenstar also announces that it has engaged Think Ink Marketing of Santa Ana, California, to conduct a marketing and awareness campaign focused on updating existing stakeholders and shareholders, as well as introducing the Company and its critical mineral exploration projects to a wider audience. The agreement is for an initial term of one month, which can be extended by Glenstar on a month to month basis following evaluation of each campaigns' effectiveness in achieving its goal. The fee for services provided by Think Ink Marketing is USD $50,000 for the first month, and then USD $50,000 for each month the agreement is extended by Glenstar.
