Mustang Energy Corp. Makes Final Preparations for

Surprise Creek Drilling Project, Saskatchewan

VANCOUVER, British Columbia, September 26, 2025 (GLOBE NEWSWIRE) -- Mustang Energy Corp. (CSE:

MEC, OTC:MECPF, FRA:92T) (the “Company” or “Mustang”) is making final preparations for the drilling

activities plann ed on the Surprise Creek Uranium-Copper Project (the “Project”). The drill program is

expected to commence on September 28th, 2025.

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 drill program will be helicopter supported and be based out of Uranium City, Saskatchewan. Mustang

Energy has engaged Base Diamond Drilling Ltd. as the contractor. Up to 2,000 meters is planned in the

Surprise Creek Fault area, which hosts high-grade uranium surface samples and historical drilling returned

results of up to 2.1 m of 4.37% U3O8 from 57 m1, 5. The purpose of the program will be to follow -up on

historic drill intercepts, to better understand the mineralization-hosting structures, and to test zones with

no previous drilling.

Nicholas Luksha, CEO of Mustang Energy, commented:

“We are proud to launch Mustang Energy’s first -ever drilling campaign beginning at the Surprise Creek

Project. This is a defining milestone for the Company as we execute on our strategy to discover and

develop critical mineral assets. With high-grade uranium and copper mineralization confirmed by historic

drilling and surface sampling, along with newly defined targets from recent geophysical surveys, Surprise

Creek has all the hallmarks of a project capable of delivering meaningful value as we advance this

inaugural program.”

About 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 just northwest of

the Athabasca Basin (see figure 1).

A major high-resolution airborne magnetic, radiometric, and VLF-EM survey completed by Thunderbird in

September 2024 identified multiple new uranium targets (see THB:ASX announcement dated 19

December 2024 titled “Exploration to commence at Rockvale Antimony-Gold Project”).

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% U3O8 from 57 m1, 5 and surface

sampling by Thunderbird returned assays up to 7.98% U3O8.2 The area of surface uranium mineralisation

extends discontinuously over a strike length of up to 500 m.2

In addition, the Project contains historical copper prospects including Bob Lake, Ellis Bay, and Waterloo

South. Historical drilling results include 9.1 m @ 2.07% Cu and 27.3 g/t Ag from surface at Bob Lake,3

and 6.6 m @ 1.31% Cu from 11 m at Ellis Bay.3 Rock chip sampling of historical copper occurrences

completed by Thunderbird in 2022 and 2023 returned assays up 61.7% Cu, 27.6% Cu and 9% Cu.2, 3

A work permit application for exploration , including drilling at the Surprise Creek Fault prospect , has

recently been approved by the Saskatchewan Government.
