Mercator Engagement and NI 43-101 Scope for Campbell-Crotser

The engagement is being led by Michael Cullen, P.Geo., Chief Geologist of Mercator, a professional geologist with over 40 years of mineral exploration experience that includes previous work in the Illinois-Kentucky Fluorspar District. Mr. Cullen visited the Campbell-Crotser project in August 2026 as part of the assignment. The technical report will describe the project's geology and mineralization, reference historical exploration and drilling, and set out a recommended work program. Mercator anticipates completing the report in the fourth quarter of 2026.

Historical Core Assay Program with the Kentucky Geological Survey

CleanTech is working with the Kentucky Geological Survey research centre at the University of Kentucky to sample and analyze historical drill cores archived at the KGS Earth Analysis Research Library in Lexington, Kentucky. The project has been tested by 77 historic drill holes, including drilling completed by Cerro Spar Corporation in the 1970s. The company states the objective is to verify historical mineral grades under modern analytical and quality-control protocols. The company has noted that this verification program will not, on its own, support a mineral resource estimate, and there is no guarantee results will be consistent with historical assays.

Stock Option Grant Approved by CleanTech's Board of Directors

Separately, CleanTech's board of directors approved the grant of 2,250,000 incentive stock options to certain directors, officers, employees, and consultants. The options carry an exercise price of CAD $0.12 per common share and are exercisable for a five-year term expiring September 16, 2031.
