Glenstar Completes Successful Trenching Program at Wildhorse Project That Uncovers New Mineralized Trend

Executive Summary

• Glenstar Minerals completed a trenching program at the Coca Cola Zone of its Wildhorse Project, exposing 15 m of east‑west quartz veining and copper oxide/sulfide mineralization.
• Surface grab samples from the zone returned notable copper grades (1.6%–5.3%) and elevated silver, bismuth, and tungsten values, supporting a potential copper‑gold porphyry system.
• The company engaged Spark Newswire for a one‑month marketing and investor outreach program with a budget of up to US$100 k.

Key Details

• Trenching Scope: Two trenches excavated wider than planned; no third trench needed.
• Bedrock Exposure: 15 m strike length, east‑west trend; four bedrock exposure cuts and 14 chip channel samples (~1.5 m each).
• Geologic Findings: Wider alteration zone than anticipated; east‑west mineralization trend intersecting previously identified north‑south trend; magnetite, epidote, pyrite alteration observed.
• Sample Assays (ALS Chemex, 28 Feb 2026):
• Copper: 1.6%, 5.3%, 2.3%, 5.1%
• Silver: average 21.6 ppm
• Bismuth: average 156 ppm (anomalous)
• Tungsten: average 72.5 ppm (anomalous)
• Operational Impact: Trench dirt to be used for foundations of two future drill pads at the Coca Cola Zone.
• Future Plans: Information will guide the first phase of drilling targeting the newly identified east‑west trend.
• Investor Engagement Initiative: Spark Newswire contracted for a one‑month term; up to US$100 k marketing budget; no securities issued as compensation.

Notable Quotes

“I’m quite excited that the visual examination of the bedrock uncovered in the trenches not only confirms what previous surface sampling suggested was occurring geologically at Wildhorse, but the discovery of the east‑west mineralization trend also indicates that this zone may be much larger than we first thought.” – Bob Marvin, Geologist, Glenstar Minerals

Materiality Assessment: Non-Material – Positive (positive exploration indicators but early‑stage and not yet tied to quantified resources).
