Delta Resources Completes Regional Till Survey, Commences Environmental Baseline Program and Advances Phase II Drilling at Delta-1 in Thunder Bay, Ontario

Executive Summary

• Delta Resources reported completion of the third phase of its 2024‑2025 regional till survey across the western Delta‑1 Gold Property, providing expanded geochemical coverage for future drilling.
• The company launched a baseline environmental program (RPAS imagery, hydrology stations, water quality monitoring, species at risk surveys, and Stage 1 archaeological assessment) to support permitting and responsible development.
• Phase II of the 2025 drilling program is underway with nine holes completed (a tenth in progress); the program targets expansion of the Eureka Gold Deposit and several satellite zones.

Key Details

• Regional Till Survey – Phase III: Conducted by IOS Géosciences Inc.; expanded coverage over the I‑Zone sector (~18 km SW of Eureka). Historical non‑NI 43‑101 drill intercepts in the area include:
• 4.32 g/t Au over 41.0 m
• 4.53 g/t Au over 14.4 m
• 4.36 g/t Au over 20.4 m (Landore Resources, 1995‑1997)
• Mini‑bulk Sample: 1,000 kg sample (Mengold Resources, 2008) returned an average grade of 9.9 g/t Au. Results will guide target selection for 2026 drilling.
• Baseline Environmental Program (2025‑2026): Led by CSL Environmental & Geotechnical Ltd.; includes:
• RPAS aerial imagery of key watercourses
• Installation and monitoring of hydrology stations
• Surface water quality sampling
• Species at Risk surveys; potential terrestrial/aquatic baseline studies (vegetation, wetlands, wildlife, fisheries, benthic invertebrates)
• Stage 1 archaeological assessment
• Phase II Drilling Program (2025): Initiated 17 Sept 2025; minimum 13 holes totaling >3,100 m to expand Eureka Gold Deposit and test satellite targets. Current focus areas:
• Shabaqua Zone – 1.3 km west of Eureka, following high‑grade surface sampling by Metals Creek & Delta
• Eureka‑South Extension – shallow mineralization south of the deposit
• Eureka‑West Extension – testing continuity westward
• Drilling Progress: Nine holes completed; a tenth hole currently underway. Assay results to be released as received.
• Qualified Person: Daniel Boudreau, P.Geo., Exploration Manager (NI 43‑101 Qualified Person) reviewed and approved technical information.

Notable Quotes

“With drilling well under way at Delta‑1, the completion of the third phase of our regional till survey, and the initiation of baseline environmental studies, the Company is making significant progress on multiple fronts.” – Ron Kopas, Interim CEO

Materiality Assessment: Non‑Material – Positive (operational updates that are favorable but not financially material).
