VANCOUVER, BC and CALGARY, AB, April 8, 2024 – Northstar Clean Technologies Inc. (TSXV: ROOF) (OTCQB: ROOOF) (“Northstar” or the “Company”) is pleased to announce that it has received the Government of Alberta’s TIER Fund approval through Emissions Reduction Alberta (“ERA”) for the Company’s formal submission related to the first milestone for the government grant (the “ERA Grant”) following the completion of detailed engineering design for its planned asphalt shingle reprocessing facility in Calgary, Alberta (the “Empower Calgary Facility”). This is the first of four funding milestones for the Empower Calgary Facility as part of the executed contribution agreement, previously announced by the Company on July 31, 2023, of up to approximately C$7.1 million.

The first milestone of the ERA Grant required the Company to meet the following requirements:

• Complete Detailed Design Basis, Process Flow Diagrams (“PFD”), Piping and Instrumentation Diagrams (“P&ID”) and Heat and Material (“H&M”) balance;
• Detailed drawings, data sheets and specifications 75% at Issued for Construction (“IFC”) or Issued for Procurement (“IFP”) stage;
• Detailed definition of required greenhouse gas measurement, monitoring and verifications (“MMV”) required to ensure they are included in detailed design;
• Technical Transfer and Commercialization Plan to provide line of sight to path to commercialization and knowledge transfer;
• List of Procurement Packages; and
• Deposits placed on the critical project long lead items.

As a result of ERA’s approval, the payment for the first milestone has been submitted for processing and the Company expects to receive payment from ERA in the near future.

Mr. Aidan Mills, President & CEO and Director of Northstar, stated, “Thanks to our partners, offtakers, vendors, our lead engineering contractor BBA Engineering and the Northstar team, we now have a fully designed facility and have moved the project into the fabrication stage. Completion of detailed design was a significant milestone for the project and delivering the additional requirements of the greenhouse gas MMV and the Technical Transfer and Commercialization Plan are important fundamental building blocks of the Northstar strategy.”

“The independent approval by ERA on these important requirements is a tremendous vote of confidence by a world class institution that is at the forefront of funding clean technology solutions,” continued Mr. Mills. “It is an exceptionally exciting time for our Company as we move forward with our first commercial facility.”
