Delta completes Phase II till sampling at Delta-1

Toronto, Ontario--(Newsfile Corp. - October 6, 2026) - Delta Resources Limited (TSXV: DLTA) (OTCQB: DTARF) (FSE: 6GO1) ("Delta" or "the Company") is pleased to announce the commencement of its Phase II 2026 till sampling program at its flagship Delta-1 Gold Project, located approximately 50 kilometres west of Thunder Bay, Ontario.

Highlights

Property-wide first-pass till sampling: Phase II will complete systematic first pass till sampling across essentially the entire 340-square-kilometre Delta-1 property .

Discovery-driven exploration approach: Till sampling contributed to the discovery of the Eureka Gold Deposit , with several additional gold-grain anomalies already identified across Delta-1.

Priority anomalies will undergo higher-resolution follow-up in early spring 2027 to vector toward potential bedrock sources and advance new targets toward drilling.

Ron Kopas, Chief Executive Officer (CEO) of Delta, commented:

"Eureka is the anchor discovery at Delta-1, yet it represents only a small portion of our 340-square-kilometre property . Delta-1 is crossed by major regional structures, including the Shebandowan Structural Zone and the Crayfish Creek Fault Corridor. In parallel with advancing Eureka, our focus is now on systematically evaluating these regional corridors to identify the next generation of gold targets across the property.

"Completing first-pass till coverage is an important step in that strategy. With several gold-grain anomalies already identified, we plan to focus higher-resolution follow-up work on the most prospective areas in early 2027, with the objective of vectoring toward new bedrock targets for drilling. The complete set of till results is expected in early 2027 and will be released alongside priority targets ahead of the summer follow-up program."

The Phase II program will extend coverage across the remaining western and southern portions of Delta-1, including recently acquired areas.

Approximately 210 till samples will be collected along sampling fences spaced approximately 1.0 to 1.2 kilometres apart, with sample stations approximately 300 metres apart along each fence.

Till sampling at Delta-1 is designed to identify gold-grain dispersion patterns within glacial sediments and vector toward potential mineralized bedrock concealed beneath glacial cover.

Phase II results will be integrated with Delta's geological, geophysical and geochemical datasets to rank anomalies and prioritize targets for higher-resolution follow-up exploration.

MULTIPLE ADDITIONAL I-ZONE SECTOR SURFACE RESULTS PENDING

Delta is awaiting assay results from additional surface sampling completed across I-Zone sector during the 2026 field program. Results received to date include channel sample intervals of 4.85 g/t Au over 8.0 metres, 2.91 g/t Au over 8.3 metres and 4.23 g/t Au over 4.3 metres from trenches 17 and 20 ( see September 21, 2026 press release ). Additional results will be released as they are received and interpreted.
