TERRA CLEAN ENERGY CORP. FILES NI 43-101 TECHNICAL REPORT FOR THE MARYSVALE URANIUM MINES PROJECT, UTAH

Terra Clean Energy Corp. has completed an independent National Instrument 43-101 (Standards of Disclosure for Mineral Projects) technical report for its wholly owned Marysvale uranium mines project located in the historic Marysvale uranium district, Piute county, Utah, United States (previously referred to by the company as the Prospector Freedom mines project). The technical report will shortly be filed under the company's profile on SEDAR+ and will be available for review by shareholders and interested parties. The technical report is being filed by the company on a voluntary basis as contemplated under Section 4.2(12) of Companion Policy 43-101CP to National Instrument 43-101 (Standards of Disclosure for Mineral Projects). The project to which the report relates is not on a property material to the company, and the technical report is not being filed as a result of a requirement of Part 4 of NI 43-101.

The technical report represents a significant milestone in Terra's systematic evaluation of the Marysvale uranium mines project and provides a comprehensive review of the property's geology, historical mining activities, exploration results and future exploration potential. The technical report incorporates the company's recently completed data compilation program, digitization of historical records, and interpretation of geological and structural information collected from the project area. The project was acquired by Terra in early 2026 and includes several past-producing uranium mines within one of the most historically productive uranium districts in the western United States. For further details, see the company's press release dated Feb. 18, 2026.

The company has also completed airborne radiometric and photogrammetric surveys, acquired and digitized available historical exploration and production data, and developed a 3-D geological model to support drill targeting and future exploration activities. Recent work has identified multiple high-priority exploration targets that will be evaluated through the company's planned summer drilling program. For further details, see the company's press release dated May 19, 2026.

Greg Cameron, chief executive officer of Terra Clean Energy, commented: "The filing of this independent NI 43-101 technical report marks an important advancement for the Marysvale uranium mines project. Over the past several months, our technical team has compiled and digitized a substantial amount of historical data, completed modern geophysical surveys, and developed a robust geological model of the property. The report confirms the strong exploration potential of the project and provides a solid technical foundation as we move toward our initial drill program. We believe the combination of historical production, encouraging exploration indicators and modern exploration techniques positions the Marysvale uranium mines project as an exciting uranium growth opportunity in the United States."

The company is currently advancing permitting for an initial 10,000-foot core drilling program designed to test priority targets identified through the technical review, airborne survey results and 3-D geological modelling. The objective of the drill program is to confirm and expand known mineralization and evaluate extensions of historically productive uranium-bearing structures.
