Northstar Clean Technologies Inc. provided an update on the site development work that began in early April at its planned asphalt shingle reprocessing facility in Calgary, Alberta (the "Empower Calgary Facility"). The site development work is part of the Company's long-term lease agreement for the Empower Calgary Facility and these expenditures are included in the landlord's (the "Landlord") obligations under this agreement. The Landlord has removed debris and topsoil that was previously on the site and begun grading and compacting the base.

Site development work will continue with: bringing in recycled granular material and placing it in the yard at the site, paving the parking lot, landscaping the front of the site, and installing lighting, fences, and foundations for the weigh scale. The site drawings were completed by the Landlord and as part of the previously announced conditional development permit issued to the Landlord by Rocky View County, Alberta on January 30, 2023. The pre-construction development permit requirements have been met and approved which allows commencement of the site development work.
