Delta Resources advances high-priority targets at I-Zone Delta-1 gold project

Toronto, Ontario--(Newsfile Corp. - July 30, 2026) - Delta Resources Limited (TSXV: DLTA) (OTCQB: DTARF) (FSE: 6GO1) ("Delta" or "the Company") is pleased to provide an update on the largest field exploration program in the Company's history at its Delta-1 Gold Project. With a team of 10 geologists now in the field, trenching, channel sampling, and prospecting activities are underway across multiple target areas within the I-Zone, as well as several surrounding high-priority gold prospects. The program is designed to evaluate multiple newly identified targets that could represent extensions of the I-Zone gold system and additional mineralized centres along the Crayfish Creek Fault corridor.

Delta is also evaluating multiple historical gold occurrences within the broader project area where grab samples returned anomalous to high-grade gold values, including reported historical grab samples grading up to 759.0 g/t Au, with additional samples returning 554.0 g/t Au, 371.9 g/t Au and 170.1 g/t Au (Inco 1989). These occurrences have not been systematically evaluated through channel sampling or drilling (Photo 1). Photo 1.

This program is designed to determine whether these occurrences represent extensions of the I-Zone system or additional mineralized centres along the Crayfish Creek Fault corridor.

By systematically trenching and sampling these targets for the first time, we aim to define their scale and continuity while prioritizing the highest-potential targets for our inaugural I-Zone drill program this fall ." "At the same time, we are advancing preparations for our upcoming definition and step-out drill program at the Eureka Gold Deposit in support of Delta's maiden mineral resource estimate. Drilling is scheduled to begin in August, while metallurgical testing and environmental baseline studies continue to advance the project, reduce development risk, and strengthen our understanding of its economic potential." Together, these targets significantly expand the exploration potential of the I-Zone-Crayfish Creek Fault corridor and represent the first systematic evaluation of several historically recognized high-grade gold occurrences. Trenching, detailed geological mapping, and hundreds of metres of channel sampling are underway to refine the geological controls on mineralization and prioritize drill targets for the planned fall drill program.

The first channel sample results are expected shortly and will be reported as they become available. The I-Zone area is located approximately 18 kilometres southwest of the Eureka Gold Deposit (Figure 1). Figure 1.

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 .
