Delta Resources completes fall drill program at Delta-1

Executive Summary

• Delta Resources Ltd. completed its 2025 fall drilling program at the Delta-1 gold property in Ontario, exceeding initial plans with 26 diamond drill holes totaling 5,237 metres.
• The program focused on advancing the understanding of the Eureka gold deposit's structural controls and testing satellite zones, including the previously undrilled Wedge sector.
• A high-resolution drone magnetic survey was also completed to refine targets for future exploration in the Shabaqua and Wedge areas; assay results are pending QA/QC review.

Key Details

• Drilling Program Completion: The 2025 fall program consisted of 26 diamond drill holes for a total of 5,237 metres, exceeding both the originally planned metreage and number of holes.
• Target Areas: Drilling focused on high-priority targets identified through 2025 surface mapping, sampling, and induced polarization (IP) geophysical surveys.
• Wedge Sector: The final two holes of the campaign were completed in the Wedge sector, a priority target area located five kilometres west of the Eureka gold deposit that had not previously been drilled by Delta Resources.
• Geophysical Survey: A high-resolution drone magnetic survey was completed to expand previous coverage and support continuing exploration efforts.
• Future Exploration: New geophysical data will help refine targets in anticipation of follow-up drilling in both the Shabaqua target area and the Wedge sector.
• Assay Status: Assay results are expected to be reported shortly after receipt, compilation, and successful QA/QC review. Delays occurred due to rapid operations and minor core-cutting issues at the start of the program.
• Eureka Deposit Context: The Eureka gold deposit extends 2.5 km in strike length, from surface to over 300 metres in depth. Mineralization has been observed up to 600 metres vertical depth and remains open in all directions.
• Historic Highlights: Previous drill intercepts include 5.92 grams per tonne Au over 31 metres (including 14.8 g/t Au over 11.9 metres) and 1.79 g/t Au over 128.5 metres.
• Property Details: The Delta-1 property covers 297 square kilometres, containing multiple corridors of intense alteration and deformation on strike with, and to the south of, the Eureka gold zone.

Notable Quotes

• "The drill campaign proceeded very efficiently and as a result, we were able to add a substantial amount of drilling beyond what was initially planned. The expanded program allowed us to test new target areas, including the Wedge sector, while continuing to evaluate extensions to the Eureka gold system." — Ron Kopas, Interim CEO
