DELTA RESOURCES KICKS OFF LARGEST EXPLORATION PROGRAM TO DATE AT THE DELTA-1 GOLD PROJECT, THUNDER BAY DISTRICT, ONTARIO

Delta Resources Ltd. has commenced its largest field exploration program to date at the company's flagship Delta-1 gold project, located in the Shebandowan greenstone belt of Northwestern Ontario.

The 2026 exploration program is strategically designed to unlock the significant discovery potential across the company's extensive 340-square-kilometre land package while continuing to expand and advance the Eureka gold deposit, where additional drilling is planned later this summer. Delta will advance multiple high-priority targets, with initial field activities focused on the highly prospective I-Zone/Crayfish Creek Fault sector, located approximately 18 kilometres southwest of Eureka.

The area is supported by several encouraging historical and recent gold results, including drill intercepts of 3.28 grams per tonne Au over 14.6 metres reported by Inco Gold (1988 to 1989) and 4.32 g/t Au over 41 m, 4.53 g/t Au over 14.4 m and 4.36 g/t Au over 20.4 m reported by Ovalbay (1995). Additionally, a 1,000-kilogram mini-bulk sample grading 9.9 g/t Au was completed by Mengold in 2008. Recent channel sampling by Delta Resources (2024) returned 1.23 g/t Au over 40.6 m, including 2.12 g/t Au over 12 m and 3.39 g/t Au over five m and 2.40 g/t Au over 16.2 m, including 5.54 g/t Au over five m.

Recent prospecting and till sampling, combined with the integration of historical geological, geophysical and geochemical data sets, have identified multiple new high-priority targets, further reinforcing the area's potential to host additional gold discoveries.

The exploration program will include systematic geological mapping, prospecting, trenching and sampling of known gold occurrences, as well as follow-up work on newly identified targets. This disciplined, data-driven approach is expected to enhance target definition, prioritize the most prospective areas and maximize the potential for new discoveries as the company advances toward its next phase of exploration success.

Delta's exploration program is fully financed, following the recent closing of a $6,562,610 charity flow-through financing at 24.5 cemts on May 27, 2026. The company's anticipated corporate funding requirements over the next three years are further supported by the recent option of its Delta-2 property in Chibougamau, Que., to Troilus Mining for $8.25-million and maintaining a 1-per-cent NSR (net smelter return) royalty, which closed on Feb. 17, 2026.

Ron Kopas, chief executive officer of Delta, commented:

"Our 2026 exploration program is designed to unlock value across the Delta-1 project through the systematic advancement of multiple high-priority targets. Recent work has highlighted significant blue-sky potential across the project, identifying several compelling opportunities within the highly prospective I-Zone-Crayfish Creek Fault corridor

"At the Eureka gold deposit, we plan to continue advancing the deposit through additional stepout drilling at both Eureka and Shabaqua, complemented by targeted infill drilling ahead of our maiden mineral resource estimate later this year.

"We will then look to move the drill in early autumn to the I-Zone/Crayfish Creek Fault sector with our fleshed out targets and expect to keep the drill rig busy throughout the rest of the year.

"Supported by a strong treasury, an extensive land package and a robust pipeline of exploration targets, we are excited to commence what we expect will be a highly active and catalyst-rich exploration season.

"In parallel, the company continues to advance environmental baseline studies, hydrological monitoring, metallurgical testing and stakeholder engagement initiatives to support the project's long-term development objectives. Exploration activities will continue throughout the field season, with results reported as they become available."

About Delta Resources Ltd.

Delta Resources is a Canadian mineral exploration and development company focused on its Delta-1 gold project in Ontario, where it has identified a large, near-surface gold system located approximately 50 kilometres west of Thunder Bay, adjacent to the Trans-Canada Highway.

The Eureka gold deposit extends over 2.5 kilometres in strike length and to depths exceeding 300 metres, with mineralization observed to approximately 600 metres vertical depth and remaining open in all directions. The property spans 340 square km and hosts multiple prospective mineralized corridors. 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.
