• Immediate follow-up drill program announced
Vancouver B.C., July 21, 2025 – TERRA CLEAN ENERGY CORP. (“Terra” or the “Company”) (CSE:
TCEC, OTC QB: TCEFF, FSE: C9O0, is pleased to announce results from the Winter 2025 drill
program and provide an update on the upcoming summer drill program at the South Falcon East
Uranium Project (the “Property”) which hosts the Fraser Lakes B Uranium Deposit.
The Property lies 18 km outside the edge of the Athabasca Basin, approximately 50 km east of
the Key Lake uranium mill and former mine (Figure 1). T he Company entered into an option
agreement with Sky harbour Resources Ltd . (“ Skyharbour”) in October of 2022 whereby the
company can earn up to a 75% interest in the Property.
Winter 2025 Assay Results
The Company conducted a helicopter supported drill program at the South Falcon East Property
between February 16 and March 26, 2025 . Seven diamond drill holes were completed on the
Fraser Lakes B Uranium Deposit, for a total of 1,927 m. The initial results of these drill holes were
reported in press releases dated March 10, 2025, and April 1, 2025.
During the winter drill program, 682 samples were submitted for geochemical analysis at the
Geoanalytical Laboratory at the Saskatchewan Research Council in Saskatoon, Saskatchewan.
Results have been received and compiled with the results presented in Table 1.
Results highlight several wide zones of uranium mineralization in holes SF0063, SF0065, SF0066,
and SF0067 drilled to test an inferred NW -SE trending fault cutting through the Fraser Lakes B
Uranium Deposit (Figure 2). The easternmost hole, SF0065, returned 18.1 m at 0.03 %U 3O8,
including a sub interval of 0.12 %U3O8 over 1.6 m. Another interval within this hole returned 0.13
%U3O8 over 0.51 m within a 3.72 m interval that ran 0.09 %U3O8.
The northernmost hole, SF0067, returned 3.87 m at 0.05 %U3O8, including a sub interval of 0.17
%U3O8 over 0.5 m. This 0.5 m interval represents the best sample of the program. Another
interval within this hole returned 0.03 %U3O8 over 8.05 m with a 0.16 %U3O8 over 0.5 m interval
within. The best intersections of the program, which are some of the better intersections for
both grade and width within the deposit, are open to the north and the east.
When compared with previously released equivalent uranium (%eU 3O8) results from the
downhole gamma logging, the lab results typically highlight wider intervals of mineralization with
higher grades than those identified within the probe. It is not unexpected or unusual for the lab
results to be higher than the equivalent gamma results. The variation is on average +5% to +30%
higher, with the large range of variation due to dealing with the overall grades , with a small
difference in grade leading to a larger apparent variation.

The typical pathfinder elements used to vector towards uranium in the basin, cobalt (Co), nickel
(Ni), copper (Cu), lead (Pb) and zinc (Zn) all appear elevated within the metasedimentary package
hosting the mineralized pegmatites, in particular Co and Ni. Elevated Pb is closely associated
with elevated uranium. Hole SF0067 contains some of the higher pathfinder values, indicating
another vector towards the north.
“The analysis results from the winter drilling program are very encouraging,” commented Trevor
Perkins, Vice President of Exploration for Terra Clean Energy Corp. “ The thick mineralized
intersections within the pegmatites and graphitic sediment package are a very positive sign. The

fact that the grades are improving to the north along the NW fault shows that we are moving in
the right direction for a higher-grade discovery,” continued Mr. Perkins.
“These are some of the best drill results to date at South Falcon,” said Greg Cameron, CEO of
Terra Clean Energy. “The drills returned multiple hits, and an 18 -meter run of uranium at the
established grade of the deposit is an extremely significant and pos itive development. Several
holes returned higher-grade values, including as much as 466 percent greater than the deposit
average. These results indicate our plan to increase the size and grade of the deposit is both
sound and compelling. Drilling will continue almost immediately, and we’re excited to see what
the next phase reveals,” continued Mr. Cameron.
Summer 2025 Drill Program
The Company is planning an extensive follow-up drill program for mid-late summer of 202 5,
consisting of approximately 2,500 meters of drilling. The purpose is to test an area highlighted
in the Winter 202 5 program where it is interpreted that a north -northwest trending brittle
structure, a north dipping structure with strong clay alteration, and mineralized pegmatites with
hydrothermal hematite alteration hosted in graphitic pelitic gneiss all intersect. This puts many
of the indicators identified as being key components for higher grade uranium mineralization all
in the same location.
It is generally accepted that for higher grade uranium deposits in the Athabasca Basin you require
several key indicators:
• Graphitic metasediments,
• Brittle reactivated basement structures,
• Reducing fluid (indicated by clay alteration),
• Oxidizing fluid (indicated by hematite alteration, transports uranium),
All these features have now been identified in the Fraser Lakes B deposit area . Where they are
projected to intercept is considered a top priority target area for the discovery of a higher-grade
unconformity related basement hosted uranium deposit and additional mineralized pegmatites.
The upcoming program will be a helicopter supported drill program encompassing seven to ten
diamond drill holes targeting an area approximately 120 to 150 m north of drill holes SF0063,
SF0065, SF0066 and SF0067 which were completed during the winter program (Figure 2). The
summer field program is anticipated to commence early-to-mid August and run for
approximately 4-5 weeks. The campaign will be executed by Terralogic Exploration Inc. under
the supervision of Terra Logic staff and C. Trevor Perkins, Vice President, Exploration for Terra
Clean Energy. Operations will be based out of a local contracting camp with helicopter support
for the daily drilling operations. The expected budget for this program is anticipated to be $ 2.0
million CDN.
”We are excited to get back in there and test where the clay alteration intersects the mineralized
zone and graphitic sediment package,” commented Trevor Perkins, Vice President of Exploration
for Terra Clean Energy Corp. “ This an exciting target as it can bring together many of the key
features associated with the known basement hosted unconformity deposits in and around the
Athabasca Basin,” continued Mr. Perkins.
