Newly Discovered Polymetallic Zone at Green Monster Project Shifts Focus of Drilling and Exploration Plan

About this update from Glenstar Minerals Inc.

[{"type":"text","content":"Vancouver, British Columbia--(Newsfile Corp. - August 13, 2025) - Glenstar Minerals Inc. (CSE: GSTR) (OTCQB: GSTRF) (FSE: VO20) ("Glenstar" or the "Company") is pleased to provide an update on the Green Monster Project in southwestern Nevada, following positive results from the drill program undertaken in May 2025 (see news release dated July 16, 2025).","length":375,"tagName":"p"},{"type":"text","content":"The ongoing review of the data obtained from this most recent drill program, along with data compiled from previous exploration field work, has raised a number of interesting questions that will hopefully be answered in the phase 2 drill and exploration plan currently being finalized.","length":285,"tagName":"p"},{"type":"text","content":"The intersection of a zone of robust polymetallic mineralization in a position 150 metres away from the main target zone of the phase 1 drill program has resulted in a change in the focus for exploration of the property, and Glenstar is now planning for extension drilling of the new zone. Hole GMST-4 was meant to test a magnetic high that was previously identified during the Company's exploration field work of the property in 2023. This new zone is approximately 10 metres (32 feet) wide and is centered on a very high-grade zinc occurrence that is >30%, with a significant assay result of up to 177 ppm of silver (161.5 g/t or 5.7 oz/t), 523 ppm of nickel (.0523%), cobalt up to 91.9 ppm (.0019%), and copper that is >.36%. The nickel and cobalt percentages reported are subjectively classified as highly anomalous for the geological structure. Mineralization in this hole was intersected at depths from ~131 metres (~430 feet) to ~142 metres (~465 feet) and occurs in the hanging wall of the Green Monster Fault Zone. All assay results were provided to the Company by ALS in Vancouver, BC.","length":1105,"tagName":"p"},{"type":"text","content":"While hole GMST-4 was simply intended to test a magnetic high, the drill placement and drilling conditions resulted in the hole barely grazing the southeast edge of the magnetic subsurface feature. This led to the discovery of unexpected strong mineralization in a significantly different stratigraphic unit that was not part of the main area of interest for the Phase 1 drill program. It is important to note that the newly discovered ...
