Integra Resources Corp.

Procurement

The Company is working through vendor evaluation and commercial negotiations for major equipment packages and expects to make its principal long-lead purchases by the end of 2026. These long-lead procurement items include:

• Merrill-Crowe plant: The Merrill-Crowe plant is used to recover gold and silver from the pregnant leach solution received from the heap leach pads on-site. Merrill-Crowe is more effective than a conventional carbon adsorption circuit as it is more efficient at extracting the silver present in DeLamar material.

• **Crushing plant:**The Company anticipates placing the order for the crushing plant and facility which consists of a primary mineral sizer and secondary low-pressure roll crusher designed to reduce ore to a P80 (particle size at which 80% of the sample material passes) of approximately 19 millimeters.

• Offsite Electrical Power: The Company has entered into an agreement with IPC for the procurement of certain long-lead equipment related to the renewal of IPC's plant and equipment. The Company expects to enter into a subsequent agreement with IPC by the end of 2026 for the construction of the electrical power supply upgrades. These phased upgrades will increase the electrical power available for the Project to approximately 6 megawatts by 2030.
