Vancouver B.C., Aug. 10, 2026 (GLOBE NEWSWIRE) -- TERRA CLEAN ENERGY CORP. (“Terra” or the “Company”) (CSE: TCEC, OTCQB: TCEFF, FSE: C9O0) is pleased to announce that it has completed the acquisition, compilation and digitization of a significant historical exploration database for its 100%-owned Marysvale Uranium Mines located in the historic Marysvale Uranium District, Utah. The project includes the past-producing Prospector and Freedom uranium mines, which historically accounted for a substantial portion of the district’s uranium production of 1.33 Mlbs U3O8 at reported average grades of 0.22% * (Terra Clean Energy Corp.)

The newly acquired historical database includes thousands of feet of drill logs, underground geological mapping, production records, assay certificates, geochemical data, mine plans, level maps, cross-sections and technical reports generated by previous operators, including work completed by Anaconda and other historical mining companies active in the district.

The Company has now digitized and integrated these datasets into a comprehensive three-dimensional geological model utilizing modern exploration software. The resulting database provides Terra with a significantly enhanced understanding of the structural controls, mineralized zones and potential extensions of uranium mineralization both along strike and at depth beneath the historical workings.

“Acquiring and digitizing this extensive historical dataset is a major milestone in advancing the Marysvale Uranium Mines Project,” stated Greg Cameron, Chief Executive Officer of the Company. “The information includes detailed drill records, underground mapping, geological interpretations and geochemical results that would be extremely costly and time-consuming to recreate today. By incorporating this data into a modern 3D model, we now have a much stronger technical foundation for targeting extensions of known mineralization and planning our upcoming drill program.”

Highlights of the historical database include:

• Historical diamond and percussion drill logs with associated uranium assay results;

• Underground geological mapping from the Prospector and Freedom mine workings;

• Historic mine plans, level maps and cross-sections documenting mined mineralized zones;

• Geochemical and radiometric survey data;

• Production records and development information from historical mining operations;

• Geological reports and interpretations prepared by previous operators;

• Data now fully digitized and incorporated into a modern 3D geological model.

Management believes the historical data confirms the significant exploration potential of the project and demonstrates that previous mining activities were focused on only a portion of the known mineralized system. The Company will utilize the newly compiled database, together with recently completed airborne radiometric and photogrammetric surveys, to finalize drill targets.

The Marysvale Uranium Mines Project is situated within the prolific Marysvale Uranium District of central Utah, an area that historically produced more than 1.33 Mlbs U3O8 at reported average grades of 0.22% *. The Prospector and Freedom mines were among the district’s most significant uranium producers and historical records indicate mineralization remains open beyond the limits of previous mining.
