• Six holes intercepted uranium mineralization
• Continuity across the deposit confirmed
• Drilling expands mineralized footprint
Vancouver B.C., April 1st, 2025 – TERRA CLEAN ENERGY CORP. (“Terra” or the “Company”) (CSE:
TCEC, OTCQB: TCEFF, FSE: 9O0, is pleased to announce the completion of the recent winter 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 southeastern edge of the Athabasca Basin, Saskatchewan,
approximately 50 km east of the Key Lake Uranium Mill and former mine (Figure 1). The Company
entered into an option agreement with Skyharbour Resources Ltd. (“Skyharbour”) in October of
2022 whereby the company can earn up to a 75% interest in the Property (see press release dated
December 30, 2024 for details of earn-in).
The Company conducted a helicopter supported drill program completing 1,927 meters in seven
diamond drill holes at the Fraser Lakes B Uranium Deposit. (Figure 3) The first three drill holes
were previously reported in the Company news release dated March 10, 2025.
“With uranium present in six of seven holes drilled this winter , and the east and west of the
property now tied together with mineralization, this was a very successful program, and we
believe we have added significant value to the Property,” said Greg Cameron CEO of Terra Clean
Energy. “We are seeing wider intervals of mineralization up to 75 meters and more consistent
spikes of higher-grade uranium with 0.16% reported in Hole SF0065. The Fraser Lakes Uranium
Deposit is shallow in nature making it ideal for an open pit scenario being only 150 meters below
surface and not far from a powerline and Cameco’s Key Lake Uranium Mill , making it a unique
opportunity, especially in a rising uranium price environment. As we continue to add pounds of
uranium and higher grades, this deposit becomes more and more valuable.”
Hole SF0065 was drilled to follow up the results of SF0063, reported in the March 10 news
release. It was targeted to intersect the same mineralized pegmatites 60 m to the northeast.
The hole was completed to a depth of 282 m and intersected a 75 m wide zone of variably
mineralized granitic pegmatites and zones within altered and graphitic pelitic gneiss. A summary
of the major zones within this mineralization are shown in Table 1 with the main highlight being
an equivalent grade of 0.02% eU3O8 over 17.5 m from 204.9 to 222.4 m, including 0.16% eU3O8
over 0.3 m . A zone of clay alteration and bleaching was intersected from 59 m to 68 m. The
presence of this alteration is a good indication that hydrothermal fluids suitable for deposition of
higher-grade uranium deposits moved through the rocks.
Hole SF0066 was drilled to a depth of 302 m, to follow the clay alteration and mineralized
pegmatites to the northwest and assist in characterizing orientation of the clay alteration and
associated structure. Drilling intersected a 50 m interval containing multiple mineralized granitic
pegmatites and zones within altered and graphitic pelitic gneiss. The most notable zone returned
an equivalent grade of 0.03% eU 3O8 over 3.4 m from 214.4 to 217.8 m, including 0.1% eU 3O8
over 0.1 m. The zone of strong clay alteration and bleaching was intersected from 57.5 m to 67.5
m. Based on oriented core data and intersections on three holes, this alteration package appears
to be dipping to the north.
Hole SF0067 was drilled to a depth of 302 m, to extend the mineralized pegmatite package to the
north and confirm the interpreted north dipping orientation of the clay alteration . Drilling
intersected a 70 m interval containing multiple mineralized granitic pegmatites and zones within
the altered and graphitic pelitic gneiss package. This interval is noted for the larger number of
higher-grade spikes at or above 0.1% eU3O8 intersected compared to the previous drilling in this
program. Down-hole gamma logging returned equivalent grades of 0.03% eU3O8 over 4.0 m from
219.8 to 223.8 m, including 0.13% eU3O8 over 0.2 m and 0.01% eU3O8 over 5.5 m from 233.7 to
239.2 m, including 0.06% eU3O8 over 0.2 m in the two widest intervals. The zone of strong clay
alteration and bleaching was intersected from 66.5 m to 73.5 m. Drilling has now extended the
deposit to the north and northeast and is still open in this direction. It is interpreted that the clay
altered structural zone identified in SF0063, SF0065, SF0066 and SF067 is dipping to the north
and will intersect the mineralized and hematite altered graphitic pelitic gneiss and pegmatites
approximately 120 to 150 m north of the current drilling. A follow -up drill program is currently
being planned to test this upgraded target area for a higher -grade unconformity related
basement hosted uranium deposit and additional mineralized pegmatites where these structures
and alteration all intersect.
“I’m very excited to announce we will be conducting a summer drilling program to immediately
follow up on the significant results received. We believe we have started to define a new
structure on the northeast side of the Property and are hopeful a basement hosted unconformity
uranium deposit, similar to Eagle Point and Rough Rider, is present. Our strategy moving forward
is to both increase the size and grade of the Fraser Lakes B deposit and to add additional discovery
to this historical resource,” said Mr. Cameron.
”The results from this drilling program are very encouraging. Drilling has shown that the deposit
is still open down dip to the northwest, north and northeast ,” commented Trevor Perkins, Vice
President of Exploration for the Company. “The presence of clay alteration within a structure on
the northeast side has upgraded this area. Where this clay alteration intersects the mineralized
conductive package is an exciting target as this can bring together many of the key features
associated with the known basement hosted unconformity deposits in the basin”, continued Mr.
Perkins.
One hole, SF0064, was completed to 239 m in the T-Bone Lake area to examine the conductive
package and alteration intersected in the area in historical drilling. An extensive package of
graphitic metasediments was intersected in this area, characterizing the conductive package.
Weak alteration was noted, however no elevated radioactivity was identified. The optimal target
in the T-Bone Lake area was not intersected.
Samples of the mineralized intervals within the drill core have been collected and shipped for
analysis at the Geoanalytical Laboratory at the Saskatchewan Research Council in Saskatoon,
Saskatchewan. Results are expected in early May. The Company will provide more detailed
results once geochemical analysis of the collected core samples is completed, reviewed and
confirmed.

QA/QC, Radiometric Equivalent Grades and Spectrometer Readings:
All drill intervals above are downhole length and sampling procedures and QA/QC protocols for
geochemical results as well as a description of downhole gamma probe grade calculations and
protocols are below. All drill core samples are shipped to the Saskatc hewan Research Council
Geoanalytical Laboratories ( “SRC”) in Saskatoon, Saskatchewan under the care of Terra
personnel for preparation, processing, and multi -element analysis by ICP-MS and ICP-OES using
total (HF:NHO3:HClO4) and partial digestion (HNO3:HCl), boron by fusion, and U3O8 wt% assay
by ICP-OES using higher grade standards. Assay samples are chosen bas ed on visual inspection,
downhole probing radiometric equivalent uranium grades , and scintillometer (Radiation
Solutions RS-125) peaks. Assay sample intervals comprise 0.5 to 1.0 m continuous half-core split
samples over the mineralized interval. These samples may also be selected for density
determination using the lost wax method. With all assay samples, one half of the split sample is
retained and the other sent to the SRC for analysis. SRC is an ISO/IEC 17025/2005 and Standards
Council of Canada certified analytical laboratory. Blanks, standard reference materials, and
repeats are inserted into the sample stream at regular intervals by Terra and SRC in accordance
with Terra’s quality assurance/quality control (QA/QC) procedures. Geochemical assay data are
subject to verification procedures by qualified persons employed by Terra prior to disclosure.
During active exploration programs , drillholes are radiometrically logged using calibrated
downhole Mount Sopris 40TGU or 2GHF probes of varying sensitivities which collect continuous
readings along the length of the drillhole. Preliminary radiometric equivalent uranium grades
(“eU3O8”) are then calculated from the downhole radiometric results. The probe is calibrated
using an algorithm calculated from the calibration of the probe at the SRC facility in Saskatoon
and from the comparison of probe results against geochemical analyses. In the case where core
recovery within a mineralized intersection is poor or non -existent, radiometric grades are
considered to be more representative of the mineralized intersection and may be reported in the
place of assay grades. Radiometric equivalent probe results are subject to verification procedures
by qualified persons employed by Terra prior to disclosure.
