Mustang Energy Corp. Announce Results from Drilling

Program at Surprise Creek Project, Saskatchewan

VANCOUVER, British Columbia, April 29, 2026 (GLOBE NEWSWIRE) -- Mustang Energy Corp. (CSE: MEC,

OTC:MECPF, FRA:92T) (the “Company” or “Mustang”) is pleased to announce it has received assay results

from all 11 diamond drill holes on the Surprise Creek Uranium-Copper (“Surprise Creek” or 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.

Surprise Creek Uranium-Copper Project

The 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 northwest 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 drilling 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 th is information as

the Company has not confirmed the accuracy or reliability of the information.

Surprise Creek and Bob Lake Drill Program

The 2025 Surprise Creek Drill Program focused on testing the continuity of polymetallic high -grade

uranium-copper vein s exposed on surfac e. Historically, the area has produced encouraging results

highlighted by historic drill hole VT20 revealing 2.1m @ 4.37% U 3O8 at 57m 1, 3. The Surprise Creek drill

program aimed to further refine historically drilled target areas where previous uranium and copper

mineralization has been observed, or recent summer 2025 prospecting and mapping with geophysical

anomalies have identified mineralization and alteration. A total of nine diamond drill holes, comprising

1123m, were completed during the 2025 fall program in the Surprise Creek area. An additional two drill

holes totaling 135m were drilled at the Bob Lake area, bringing the combined drilling total for the Surprise

Creek and Bob Lake areas to 1,258m. The core samples collected from drill holes within the Surprise Creek

and Bob lake areas were sent to SRC geoanalytical for geochemical analysis. Both locations warrant

additional follow-up with ground drill targeting to test anomalies at deeper subsurface depths.

Mustang’s CEO, Nicholas Luksha is encouraged by the drilling, saying, “These initial drill results represent

a very encouraging start for the project, with high -grade copper mineralization intersected at shallow

depths. Intervals such as 2.69% copper over nearly 5 metres, including significantly higher -grade zones,

validate our geological model and confirm the presence of a robust mineralized system. With

mineralization starting close to surface and supported by strong surface expressions, we see potential to

expand both along strike and at depth. We are excited to advance the project with additional drilling as

we work to better define the scale and continuity of this high-grade copper system.”

Key Highlights

Surprise Creek

• 9 drill holes totalling 1123m comprising 333 samples including QA/QC with the highest grading up

to 535 ppm U308

• High grade Uranium on surface traced discontinuously over a strike length of approximately 500

meters2

Bob Lake

• 2 drill holes totalling 138m comprising 68 samples including QA/QC

• Drill hole BOB25 -002 intersected 4.9 metres of copper mineralization beginning at 6.8 metres

depth, grading 2.69% Cu, including 0.5 metres assaying up to 15.9% Cu. A separate 0.7 metre

interval downhole at 22.5 metres returned grades of up to 3.91% Cu.

• Drill hole BOB25-001 intersected 2.4 meters of copper mineralization at 6.2 meters depth, grading

1.09% Cu, including 0.5 meters grading up to 3.57% Cu

• Both drill holes are located within an easily accessible area with shallow mineralization

• 3 metre wide by 9 metre strike length mineralized quartz vein on surface

Future Steps

Follow-up drilling and ground prospecting is warranted at the Bob Lake and Surprise Creek areas based on

the encouraging surface mineralization and the highlighted drill results listed above. Several geophysical

anomalies have been identified across Surprise Creek that require additional ground prospecting follow-

up to refine targets and prioritize future drilling. Future drilling will focus on evaluating high-grade surface

expressions at deeper depths to determine their subsurface continuity and potential scale.

The Project is a multi -commodity project with prospective drill targets beyond the immediate areas of

focus, including the Maimann Lake area and Surprise Creek NW area where surface sampling produced up

to 63.4% Cu and 7.93% U3O8 (see the Company’s news release dated April 17, 2026 for prospecting assay

results).

QAQC

Geochemical Sampling Procedure

All drill core samples were transported by helicopter to the logging facility in Uranium City where they

were logged, photographed, sampled and bagged on site. Samples were then shipped by air to Fort

McMurray, Alberta by McMurray aviation then transported by truck to SRC Geoanalytical in Saskatoon,

Saskatchewan. Blanks, certified reference material (CRM), and duplicates were inserted into the sample

stream at regular intervals of 1:25 or better in accordance with Axiom Groups 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. Drill core samples collected for analysis at Surprise

Creek were sent to SRC Geoanalytical Laboratories in Saskatoon, Saskatchewan for preparation and
