Audio By Carbonatix

TORONTO--(BUSINESS WIRE)--Mar 2, 2026--

Generation Mining Limited (“GENM” or the “Company”) is pleased to announce the appointment of Ausenco Engineering Canada ULC (“Ausenco”) as the Engineering, Procurement and Construction Management (“EPCM”) partner for the Marathon Copper- Palladium Project (the “Project”) located in Northwestern Ontario.

Following a comprehensive evaluation and negotiation process, Ausenco was selected as GENM’s EPCM partner based on its strong technical capabilities, proven project delivery experience in Ontario, and alignment with GENM’s execution strategy and long-term business objectives.

Ausenco demonstrated a clear understanding of the Project’s scope, risk profile, and value drivers, while aligning closely with GENM’s priorities for disciplined capital management, constructability, operational readiness, and responsible project development. Ausenco recently completed the updated Feasibility Study, and the quality of this work was a key criteria as part of the selection for a key strategic partner in the execution phase and contributed to GENM’s confidence in advancing the Project.

GENM and Ausenco engaged in a collaborative negotiation process, resulting in a commercial and execution framework designed to achieve common objectives, including:

• Delivery certainty across scope, cost, and schedule
• Strong governance and reporting discipline
• Aligned outcomes for ensuring project success against the recently completed work reviewed by our lenders
• Effective integration between the parties across engineering, procurement, and construction management
• A shared commitment to safety, sustainability, and stakeholder engagement

“Ausenco distinguished itself as a partner that not only brings deep EPCM expertise but also shares GENM’s commitment to a disciplined, transparent, and value-focused execution model,” said Clinton Swemmer, VP Projects. “We value Ausenco’s proven resilience in difficult industry conditions and its strong understanding of execution requirements within Ontario. We also appreciate the constructive and solutions-oriented approach taken throughout the negotiation process.”

“Being awarded the EPCM contract for the Project is a milestone we've been building toward through every stage with GENM. Working together through the feasibility update has only deepened our confidence in what this partnership can achieve,” said Dan Wilford, Vice President Project Execution for Ausenco. “Ontario has a proud history of delivering world-class resource projects, and our regional and global execution team intend to bring that same focus on innovation, resilience, and hard-won experience that has come to define the integrated GENM and Ausenco project team. This is exactly the kind of project we like to deliver.”

GENM and Ausenco will now advance into detailed design and execution readiness activities under a Limited Notice to Proceed (“LNTP”) phase, during which the parties will finalize the EPCM contract. These activities will progress in parallel with GENM’s ongoing project financing process, with the intent of commencing field execution in the third quarter/fourth of 2026, subject to financing and customary conditions.

Under the EPCM mandate, Ausenco will be responsible for detailed engineering, procurement, construction management, and related project services supporting the development and delivery of the Project.

This appointment represents a key milestone as GENM advances the Project toward the execution phase.
