Delta Resources starts environmental program at Delta-1

Executive Summary

• Delta Resources completed the third phase of its 2024‑2025 regional till sampling program across the western portion of the Delta‑1 property, expanding geochemical coverage and identifying new drill targets for 2026.
• The company launched a comprehensive environmental baseline program (RPAS imagery, hydrology stations, water quality monitoring, species‑at‑risk surveys, archaeological assessment) that will run through 2025‑2026 to support future permitting.
• Phase II of the 2025 drilling campaign is underway; nine holes (≈2,800 m) have been completed and a tenth is in progress, with a total planned minimum of 13 holes (>3,100 m) targeting extensions of the Eureka deposit and the Shabaqua zone.

Key Details

• Till Survey: Conducted by IOS Geosciences Inc.; third phase of 2024‑2025 program; 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, and 4.36 g/t Au over 20.4 m; a 1,000‑kg bulk sample returned 9.9 g/t Au. Results will guide 2026 target definition.
• Environmental Baseline Program (2025‑2026): Led by CSL Environmental & Geotechnical Ltd.; activities include:
• RPAS aerial imagery of key watercourses.
• Installation and monitoring of hydrology stations.
• Surface water quality sampling.
• Species‑at‑risk surveys plus potential terrestrial/aquatic baseline studies (vegetation, wetlands, wildlife, fisheries, benthic invertebrates).
• Stage 1 archaeological assessment.
• Phase II Drilling (2025 Program): Commenced 17 Sept 2025; minimum 13 holes, >3,100 m total depth. Current focus areas:
• Shabaqua zone: ~1.3 km west of Eureka, following high‑grade surface sampling by Metals Creek and Delta.
• Eureka‑South extension: Targeting shallow mineralization south of the main deposit.
• Eureka‑West extension: Testing continuity toward the west.
• Drilling Progress to Date: Nine holes completed; a tenth hole currently underway. Assay results will be released as they become available.
• Management Comment: Ron Kopas (interim CEO) highlighted that the combined survey, environmental work, and drilling “significantly progress multiple fronts,” positioning Delta‑1 for future growth and low‑cost mining potential.

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… we have the potential to be one of the lowest cost mining camps in the country.” – Ron Kopas, Interim CEO
