Delta Resources starts 2026 till sampling at Delta-1, Thunder Bay

Toronto, Ontario--(Newsfile Corp. - August 4, 2026) - Delta Resources Limited (TSXV: DLTA) (OTCQB: DTARF) (FSE: 6GO1) ("Delta" or "the Company") is pleased to announce the commencement of its 2026 till sampling program at its flagship Delta-1 Gold Project, located approximately 50 kilometres west of Thunder Bay, Ontario.

The 2026 program is designed to complete the remaining southeastern portion of the property, including claims acquired in 2024, bringing geochemical till coverage to near-complete coverage of the entire Delta-1 land package. The area covered by the survey hosts several historical gold occurrences including the North Zone, where mineralization is reported to average approximately 3.0 g/t Au over 2.4 metres across a 55-metre strike length, with channel samples returning up to 4.25 g/t Au over 2.9 metres, and the Ternowesky Zone, where sampling is reported to have returned up to 35.7 g/t Au and 295 g/t Ag (Jalna Resources 1984 1 ).

With Delta-1 covering approximately 340 square kilometres, systematic till sampling is a cornerstone of Delta's exploration strategy, providing an efficient means of evaluating this district-scale property and generating new drill targets by identifying concealed gold mineralization across the Delta-1 district. The effectiveness of this approach was demonstrated by the discovery of the Eureka deposit, which was initially identified through a till anomaly and subsequently advanced through follow-up exploration and drilling.

The survey will collect approximately 243 till samples along fences spaced 1.0 to 1.2 kilometres apart, with sample stations every 250 to 300 metres. The program is specifically designed to identify gold grain dispersion patterns that could vector toward blind or concealed bedrock gold mineralization beneath glacial cover. Previous till surveys successfully identified several gold grain anomalies that contributed to the definition of current exploration targets.

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

"This program represents another important step in systematically evaluating the full potential of Delta-1. By extending till coverage across virtually the entire property, we expect to significantly enhance our understanding of gold dispersion patterns and refine future exploration targets. Delta-1 continues to demonstrate district-scale potential, and this work will provide another valuable layer of geological information.

Our next drilling program begins later this month and is currently planned to run well into 2027. With so many targets already, our goal is to use the data to optimise where we focus next - what is clear is we have a busy year ahead of us."

The approximately 25-day program will combine excavator-supported and conventional till sampling to access basal till beneath glaciolacustrine sediments where required. Samples will undergo both gold grain counting and fine-fraction geochemical analysis to identify and prioritize new exploration targets.

Results are expected later this year and will be integrated with previous till surveys to refine drill targeting across the property.

About Delta Resources Limited

Delta Resources is a Canadian mineral exploration and development company focused on advancing its Delta-1 Gold Project in Ontario. The Company has identified a large, near-surface gold system located approximately 50 kilometres west of Thunder Bay, adjacent to the Trans-Canada Highway. The Delta-1 property covers approximately 340 square kilometres and hosts multiple gold-bearing corridors, including the Eureka Gold Deposit and the highly prospective I-Zone-Crayfish Creek Fault trend.

The Eureka Gold Deposit extends over 2.5 km in strike length and to depths exceeding 300 metres, with mineralization intersected to approximately 600 metres vertical depth and remaining open in all directions. Highlights include drill intercepts such as 5.92 g/t Au over 31 m (including 14.8 g/t Au over 11.9 m) and 1.79 g/t Au over 128.5 m .
