Advancing High-Potential Nevada Critical Minerals Portfolio as Major Drill Program Nears Assay Results: Glenstar Minerals: Stock Symbol: GSTRF
Ohio Pen/10331940

VANCOUVER, British Columbia - OhioPen -- As global demand for critical minerals continues to accelerate due to expanding artificial intelligence infrastructure, electrification initiatives, advanced electronics manufacturing, energy storage systems, and defense technologies, investors are increasingly seeking exposure to companies exploring for the metals that may power the next generation of industrial growth.

One company attracting growing attention in the junior mining sector is Glenstar Minerals Inc. $GSTRF $GSTR, a mineral exploration company focused on discovering and developing polymetallic deposits containing several minerals classified as strategically important to modern technology and energy applications.

With active exploration programs underway in Nevada and a series of recent operational milestones achieved, Glenstar has entered what many investors may view as a potentially transformative stage in its development.

Wildhorse Project Emerging as Flagship Asset

Glenstar's Wildhorse Project, located in Mineral County, Nevada, has rapidly become one of the Company's most closely watched exploration assets. The property now consists of 89 mineral claims covering approximately 1,780 acres and hosts multiple mineralized zones with evidence of gold, copper, antimony, silver, tungsten, and bismuth mineralization.

Historical records, geological mapping, trenching programs, surface sampling, and recent drilling activities have all pointed toward the presence of a potentially significant polymetallic mineral system.

Initial field examinations identified quartz veinlet zones containing more than 1 gram per tonne gold, approximately 1% copper, and up to 6,100 ppm antimony. Additional sampling revealed the presence of tungsten and bismuth, two minerals considered increasingly important within advanced manufacturing and emerging technology supply chains.

High-Grade Gold Discovery Strengthens Exploration Thesis

One of Glenstar's most significant developments occurred earlier this year when trenching work at the Coca Cola Zone returned exceptionally encouraging assay results.

The Company reported a high-grade gold sample measuring 23.6 grams per tonne gold within a mineralized structural zone that also contained approximately 1% copper. Management believes this mineralized trend extends for at least 100 meters and became a primary target of the Company's Phase 1 drilling program.

For investors, discoveries of this magnitude often represent important indicators that a broader mineralized system may exist beneath surface exposures.

Successful Phase 1 Drill Program Completed

Building on encouraging trenching results, Glenstar recently completed its Phase 1 reverse circulation drilling campaign at Wildhorse.

The program included ten drill holes across the Coca Cola and Rattlesnake Zones, with drilling expanded beyond original plans after field observations revealed widespread mineralization and alteration. Total drilling increased from approximately 3,500 feet to roughly 4,300 feet.

According to the Company, every hole drilled encountered significant alteration, quartz veinlets, and indications of poly-sulfide mineralization.

Particularly encouraging were observations within the Rattlesnake Zone, where drilling intersected what management described as robust area-wide occurrences of polymetallic mineralization both near surface and at depth.

Project Geologist and Exploration Manager Bob Marvin noted that visual observations suggest the mineralization may be both widespread and considerable across the targeted zones.

860 Samples Submitted for Assay

Perhaps the most anticipated near-term catalyst for Glenstar investors is the pending release of assay results from the recently completed drilling campaign.

In May, the Company announced that a total of 860 drill samples had been submitted to Paragon Geochemical Inc. in Nevada for analysis. Management indicated results were expected approximately 30 to 45 days after submission, placing investors squarely within the anticipated reporting window.

Assay results will provide the first quantitative measurements of mineral grades encountered during the Phase 1 program and could help validate the extensive mineralization observed visually during drilling.

For many junior exploration companies, drill assay results often serve as major valuation drivers and can significantly influence future exploration plans.

Multiple Critical Minerals Exposure

Unlike many exploration companies focused on a single commodity, Glenstar offers exposure to a diversified suite of critical and precious metals.

Among the minerals identified at Wildhorse are:

• Gold and Silver, traditionally viewed as stores of value and monetary metals.
• Copper, a foundational metal required for electrification, renewable energy systems, and data center infrastructure.
• Antimony, designated as a critical mineral by several governments due to its use in defense, semiconductors, flame retardants, and energy storage technologies.
• Tungsten, valued for its strength, high-temperature resistance, and industrial applications.
• Bismuth, increasingly utilized in advanced alloys, electronics, and specialty manufacturing.

This diversified mineral profile may provide Glenstar with multiple pathways toward resource development success.

Additional Nevada Growth Opportunities

Beyond Wildhorse, Glenstar continues advancing its Green Monster Project in Nevada.

Recent drilling at Green Monster identified a geologically complex polymetallic system, while previous drilling campaigns reported high-grade zinc, silver, and copper mineralization. The Company has continued to invest aggressively in exploration efforts across both flagship projects.

Management has previously highlighted raising more than C$3 million to accelerate drilling and exploration activities across its project portfolio, strengthening the Company's ability to pursue ongoing discovery efforts.

Expanding Market Awareness

Recognizing the importance of investor communication, Glenstar recently launched a strategic awareness initiative through Blossom Social, one of North America's largest social investing platforms with over 700,000 retail investors.

The campaign is designed to educate investors regarding mineral exploration, critical minerals, and Glenstar's ongoing project developments.

Looking Ahead

As the global race to secure critical mineral supply chains intensifies, exploration companies capable of identifying economically viable deposits may find themselves operating in an increasingly favorable environment.

For Glenstar Minerals, several potentially important catalysts now appear to be converging:

• Pending assay results from 860 drill samples at Wildhorse.
• Continued advancement of multiple mineralized zones across the project.
• Exposure to several strategic critical minerals and precious metals.
• Ongoing development of the Green Monster Project.
• Growing investor awareness through expanded market outreach initiatives.

While exploration investing always carries inherent risks, Glenstar's recent operational progress, encouraging geological indicators, expanding land package, and upcoming assay results have positioned the Company as a junior exploration story that investors interested in critical minerals may wish to follow closely during the remainder of 2026.
