Dear Shareholders,

Further to our August 12, 2025, communication, Delta Resources is pleased to provide an update on its 2025 exploration program. Our objective is to highlight the value gap between Delta’s current market position and the significant potential of the Thunder Bay region, where the Company is advancing what we believe could become one of Canada’s next major mining camps. With a large, strategic land position and a growing gold discovery at the Delta-1 Property, Delta is uniquely positioned within the highly prospective yet, in our estimation, underexplored Shebandowan Greenstone Belt.

Delta’s exploration strategy is increasingly focused on defining near-term, developable higher-grade starter pit opportunities, as the Company begins to outline the framework for a possible future mine development at the Eureka Gold Deposit. This strategy emphasizes the potential to rapidly add near-surface ounces that could enhance early mine economics and project optionality, while mineralization at depth remains an important longer-term opportunity.

1. EUREKA SOUTH TARGET

Drilling at Eureka South will build on trenching and drilling successes that outlined near-surface gold mineralization, including 0.84 g/t Au over 11 m. Planned holes will test for possible westward and eastward extensions along a corridor of anomalous gold and associated trace elements identified from 2025 grab sampling, while also testing for structural related controls.

This sector offers an opportunity to add near-surface ounces and directly expand the Eureka Gold Deposit footprint.
