Mustang Energy Corp. Announce Results from
Sampling Program at Surprise Creek Project,
Saskatchewan
VANCOUVER, British Columbia, April 17, 2026 (GLOBE NEWSWIRE) -- Mustang Energy Corp. (CSE: MEC,
OTC:MECPF, FRA:92T ) (the “ Company” or “ Mustang”) is pleased to announce the c ompletion of
geochemical analysis of rock samples taken at the Surprise Creek Uranium-Copper (the “Project”), located
in a prospective region known for its mineral potential northwest of the Athabasca Basin. The Company
entered into an option agreement (the “ Option Agreement ”) with Thunderbird Resources Ltd.
(“Thunderbird”) to acquire an undivided 80% interest in the Project. Please refer to the Company’s news
release dated June 4, 2025, and June 16, 2025, as filed under the Company’s SEDAR+ profile, for further
details regarding the Option Agreement.
The field program at Surprise Creek included surface prospecting activities and detailed rock sampling,
aimed at further refining target areas and outlining mineralization and alteration. Surface samples were
collected from nine locations of interest where previous uranium and copper mineralization has been
observed, or geophysical anomalies have been identified. The results outline the mineralization potential
of uranium at the Surprise Creek area, and copper mineralization at the Bob Lake and Maimann Lake
areas. Both locations warrant additional follow -up with ground prospecting and drill targeting to test
anomalies at deeper subsurface depths.
Surprise Creek Uranium-Copper Project
The Surprise Creek Project is located 25 km north-west of the Beaverlodge Uranium District, which hosts
the historical uranium mines of Gunnar and Eldorado (Ace -Fay-Verna) and is located north west of the
Athabasca Basin (see figure 1).
Mustang holds an option to acquire an 80% interest in the Project from Thunderbird Resources under an
agreement announced on June 4 and June 16, 2025. The program is fully permitted, with exploration
approvals granted by the Saskatchewan Government.

Cautionary Statement
The Company advises that, notwithstanding their proximity and location, discoveries of minerals on or near historic
mines such as Gunnar and Eldorado, and any promising results thereof, are not necessarily indicative of the
mineralization of, or located on the Project, or the Company’s ability to commercially exploit the Project, or to locate
any commercially exploitable deposits therefrom. The Company cautions investors on relying on this information as
the Company has not confirmed the accuracy or reliability of the information.
2025 Surprise Creek Prospecting Targets
A strong uranium radiometric anomaly has been identified at the previously defined Surprise Creek Fault
drill target, where historical drilling returned results of up to 2.1m of 4.37% U 3O8 from 57m1,3. During
the summer prospecting program , 37 grab samples were collected by Axiom in the Surprise Creek area
which hosts polymetallic vein type uranium-copper mineralization and returned encouraging assay results
of up to 9.39% and 7.93% U3O8 with up to 3.11% Cu values (Table 1). Uranium surface mineralization has
been traced discontinuously over a strike length of approximately 500 meters2, highlighting the potential
scale of the system. In addition to uranium mineralization, the program confirmed the presence of several
historic copper targets, significantly enhancing the project's multi-commodity value proposition.
2025 Bob Lake and Maimann Lake Prospecting Targets
Surface sampling carried out at the historic Bob Lake and Maimann Lake areas returned encouraging
copper assays. Exploration at Bob Lake, which included a total of 16 grab samples returned significant
values of up to 11.8% and 5.27% Cu with gold values reaching 1.2 g/t and 0.9g/t Au (Table 2). An additional
12 grab samples were taken from the Maimann Lake showings and yielded very high-grade surface
samples reaching 63.4% and 43.38% Cu (Table 2). These results confirm the presence of high-grade copper
within the project area and demonstrate a diverse mineral footprint that complements the company’s
primary uranium targets.

Nick Luksha, CEO of Mustang Energy, commented:
“We’re strategically positioning the Company by advancing the Surprise Creek project, which offers dual
potential within the critical minerals space. The encouraging surface results we’ve generated to date will
play a key role in shaping the design of our future drill programs, allowing us to target areas with the
highest potential more effectively. As we move forward, we’re excited to build on this momentum with
additional surface prospecting as we continue to unlock the broader potential of the project.”

Field procedures
Rock samples from the prospecting program were described, photographed, and assigned unique IDs in
the field. Sample locations and observations were recorded using handheld GPS units. All rock
samples were bagged, sealed and stored at the Uranium City base before shipment to SRC Geoanalytical
Laboratories in Saskatoon at the end of the program.
Lab analysis for Surprise Creek
Rock Samples collected for analysis at Surprise Creek were sent to SRC Geoanalytical Laboratories in
Saskatoon, Saskatchewan for preparation and processing. Samples were tested using ICP-MS and ICP-OES
multi-element analysis using total and partial digestion. Samples were tested using the ICPMS4AT multi-
element exploration package. All samples marked as radioactive upon arrival to the lab were also analyzed
using the U3O8 assay (reported in wt.%). Given the polymetallic nature of the Surprise Creek area the
samples were tested using ICP-OES multi-element analysis ICP3 partial digestion and ICP4 total digestion
for base metal analysis. SRC Geoanalytcial Laboratories is an ISO/IEC 17025:2005 and Standards Council
of Canada certified analytical laboratory. Blanks and standard reference materials were inserted into the
sample stream at regular intervals in accordance with Axiom Group’s quality assurance/quality control
(QA/QC) protocols. All samples passed internal QA/QC protocols and the results presented in this release
are deemed complete, reliable, and repeatable.
Lab Analysis for Bob Lake and Maimann Lake
