Terra Clean Energy Corp. Announces Agreement to Earn 100% Interest in 75 Past Producing Uranium Claims on The San Rafael Swell, Utah, United States

Vancouver B.C., September 16, 2025 – TERRA CLEAN ENERGY CORP. (“Terra” or the “Company”) (CSE: TCEC, OTCQB: TCEFF, FSE: 9O0, is pleased to announce terms to acquire up to a 100% interest in 75 uranium claims in Emery County, Utah, United States.

Transaction Highlights 

• Nine Past Producing Uranium mines covered on the Claims having produced several hundred thousand tons of ore grading up to 1% U308
• Visible Uranium, Vanadium, Copper and Cobalt at Surface with numerous uranium readings up to 21,000 CPS equating to grades .22% U308 
• Close Proximity to major roads with good year around access, power and a uranium mill located 75 miles drive
• Strong Government support for nuclear power and uranium mining projects and a stated objective to reduce reliance on foreign nuclear fuel  
• Staged earn-in allows the company to optimize exploration programs
• Provides Terra shareholders exposure to two North American assets both with near surface Uranium opportunities in low-risk jurisdictions

Greg Cameron stated “One of my stated goals with Terra was to add another low-risk uranium project to the Company and this transaction does just that. Having toured the properties with our VP Exploration, it is clear from the moment you arrive you are in a uranium district with many old workings, adits, shafts and old infrastructure. I am excited to see work begin this fall and believe there to be a clear path to add significant value for our shareholders.”

Rationale Behind the Acquisition

Green Vein Mesa and Wheal Anne Claims offer exposure to uranium projects in the USA with excellent upside in a significant historical uranium district. Terra has made a strategic decision to acquire the Green Vein Mesa and Wheal Anne Claims due to the belief there is more minable uranium present. It is important to note that the encompassing claims have a production history. Both sets of claims are in ideal locations, situated near main roads, secondary roads and have access to power and water sources. In the past, mining operations focused on ore found at or near surface. The process of oxidation led to the formation of various secondary uranium minerals. The Trump Administration has recently enacted historic policies designed to accelerate nuclear power and uranium mining activity in the country” 

“This initial project in San Rafael Swell offers significant upside as it is clear that these old mines were abandoned in the 1970’s due to a uranium market collapse not because they ran out of uranium to mine,” stated Greg Cameron, CEO of Terra. “We believe strongly that we can expand on the previous work through modern exploration technologies like 3D modelling”  added Trevor Perkins VP Exploration.

Project Overview

The San Rafael Swell is a large, uplifted, doubly-plunging anticline in east-central Utah and the Swell forms part of, but contrasts with the surrounding flat-lying rocks, of the Colorado Plateau, a significant uranium mining district in the Western United States. Historical uranium production was undertaken in the region between the late 1940’s into the 1970’s.  No significant work has been completed in the region in the past 50 years.

The rocks in the San Rafael Swell are predominately sedimentary (Pennsylvanian through Cretaceous), including Triassic and Jurassic formations that are known to host uranium. The project area is underlain by Triassic aged sedimentary rocks of the Moenkopi and Chinle formations. The Chinle outcrops in a continuous belt around the San Rafael Swell and on isolated buttes through the center of the swell. It is widely believed that volcanic ash is the source of uranium for many deposits in the swell. All existing mines and prospects in the Chinle are in the lower, bentonitic part of the Chinle in channel-fill sandstone and surrounding siltstones of the lower Chinle Formation. .   In the Green Vein Mesa area these occur as scour channel fill at the contact with the underlying Moenkopi Formation.

The project is separated into two claim groups 10 km apart. The Wheal Anne Claim Group is the southwest of the two and encompasses approximately 130 hectares covering the former producing Lucky Strike Mine and related uranium occurrences. The Lucky Strike Mine was discovered in 1949 and produced more than 10,000 tons of ore grading 0.22% U₃O₈ and 0.09% V₂O₅. ^[1]

The Green Vein Mesa Claim Group to the northeast encompasses approximately 300 hectares and covers the former producing Payday Mine, Hertz Mine, and Green Vein group of mines. Production numbers for these mines were not located, however the Hertz Mine reportedly had local samples up to 1% U₃O₈.^[2]
