Strategic Funding and Project Advancement

Together, these funding streams are expected to accelerate the Company’s path toward near-term surgical mining copper production.

Use of Proceeds

• Initial deployment of Novamera Inc.’s Surgical Mining™ system
• General working capital

The Zone 2 Surgical Mining™ pilot program is advancing under a Turnkey Surgical Mining Services Agreement with Novamera (executed October 9, 2025).

Northstar is progressing toward a Notice-to-Proceed decision, subject to permitting, financing, and completion of technical studies. A compliant mineral resource estimate will be completed prior to any production decision.

• DIGITAL – Canada’s Global Innovation Cluster for digital technologies
