Terra Clean Energy reports airborne survey results at Prospector Freedom, Utah; summer program underway

Vancouver B.C., May 19, 2026 (GLOBE NEWSWIRE) -- TERRA CLEAN ENERGY CORP. (“ Terra ” or the “ Company ”) (CSE: TCEC, OTCQB: TCEFF , FSE: C 9O0) is pleased to announce highly encouraging initial results from recently completed airborne radiometric and Photogrammetric surveys at its Prospector Freedom Uranium Property in Piute County, Utah (the “ Prospector Freedom Project ”). The Company has also mobilized preparations for an extensive summer exploration program designed to rapidly advance the project toward drill-ready targets. The Prospector Freedom Project is located within a historically productive uranium district that has produced approximately  1.33 Mlbs U 3 O 8 at reported average grades of 0.22% * and benefited from extensive historical exploration activity.

Previous operators reported strong uranium grades and continuity along multiple mineralized trends, underscoring the district-scale potential for additional discoveries and future resource expansion. Multiple High-Priority Uranium Targets Identified The integrated airborne survey program was completed across the Company’s newly expanded 380-acre land package and has successfully identified several high-priority exploration zones exhibiting characteristics consistent with structurally controlled vein-style uranium mineralization.  The survey was conducted by Land Survey Advisors of Heber City, Utah using a DJI Matrice 400 RTK quadcopter using terrain following and equipped with a Georadis D230A gamma ray spectrometer and a Zenmuse P1 45-megapixel mapping camera.   The radiometric survey outlined numerous discrete uranium anomalies associated with favorable host lithologies and established regional mineralized trends. These anomalies are interpreted as potential near-surface uranium-bearing zones and represent compelling follow-up targets for the Company’s upcoming field program.

This integrated dataset has generated several compelling drill targets and provides a strong foundation for the next phase of exploration.” Strategic Expansion of the Property Position Earlier this year, Terra strategically expanded the Prospector Freedom Project through the staking of an additional 14 Bureau of Land Management (“BLM”) lode claims surrounding the original six claims, substantially increasing the Company’s footprint to 380 acres within this highly prospective historical uranium district.  The expanded land package was assembled following detailed historical data compilation and regional geological interpretation, securing additional prospective ground believed to host favorable uranium mineralization. “We are excited with the data provided through these surveys”, commented Trevor Perkins, VP Exploration of Terra.  “When combined with the digital dataset we continue to compile for the property, numerous targets have been identified for follow-up and potential drilling, with the ultimate goal of a 3D model and resource estimate on the horizon”, continued Mr. Perkins. Summer Exploration Program & Drill Permitting Underway Building on the positive survey results, Terra is now advancing a targeted summer exploration program that will include: - Ground-truthing of airborne anomalies - Detailed geological mapping - Geochemical sampling - Structural interpretation and target refinement - Advancement of priority drill targets Drill permitting is actively underway.

Land Survey Advisors of Heber City, Utah, has been engaged to finalize permitting with the U.S. Bureau of Land Management and the Utah Division of Oil, Gas and Mining. All exploration activities are being conducted in accordance with applicable regulatory requirements and industry best practices. Terra remains committed to responsible exploration and environmental stewardship as it advances the Prospector Freedom Project.
