Mustang Energy Corp. Enters Option Agreements with Thunderbird Resources Ltd.
Vancouver, British Columbia, June 4, 202 5, Mustang Energy Corp. ( CSE:MEC, OTC:MECPF, FRA:92T ) (“ Mustang” or
the “Company”) is excited to announce that it has entered into two strategic option agreement s with Thunderbird
Resources Ltd. (“Thunderbird”) to acquire an undivided 80% interest in certain mineral tenements held by Thunderbird
located in the Athabasca Basin of Northern Saskatchewan (the “Project”). The Option marks an important step for Mustang
as it continues to expand and build its land package in this promising uranium district.
The Company entered into an option agreement (the “Cluff Lake Agreement”) with Thunderbird, dated June 3, 2025, to
acquire an undivided 80% interest (the “ Cluff Lake Option ”) in certain mineral tenements held by Thunderbird in and
around Cluff Lake (the “Cluff Lake Project”).
Concurrently with the Cluff Lake Agreement, the Company entered into a second option agreement (the “Surprise Creek
Agreement”, and together with the Cluff Lake Agreement, the “ Agreements”) with Thunderbird, dated June 3, 2025, to
acquire an undivided 80% interest (the “Surprise Creek Option”, and together with the Cluff Lake Option, the “Option”) in
certain mineral tenements held by Thunderbird in and around Surprise Creek, Pring Lake, and Ellis Bay/Bob Lake (the
“Surprise Creek Project”).
“We are excited to partner with Thunderbird Resources on the Cluff Lake North and Surprise Creek Projects . This
agreement advances Mustang’s Athabasca Basin strategy. With a strong foundation in place through targeted claim
staking and acquiring early-stage projects, we’re now focused on advancing high -priority, drill -ready assets. Our
technical team is developing plans for field programs at Cluff Lake North and Surprise Creek Projects to refine drill
targets and evaluate underexplored structural corridors with strong discovery potential.” said Nicholas Luksha, CEO of
Mustang Energy Corp.
Cluff Lake North Uranium Project
The Cluff Lake Project comprises a group of five mineral claims located in a highly prospective area around 12km north -
east of the historical Cluff Lake uranium mine on the western flank of Canada’s world-class Athabasca Basin.
Figure 1: Cluff Lake North Project Overview5
Thunderbird completed a MobileMT survey in 2024 which delineated several basement conductors in the Moose Lake
area of the project, which are potential pathways for uranium mineralising fluids (see ASX: THB announcement dated 17th
October 2024 titled “Multiple Uranium targets identified by detailed EM surveys at Cluff Lake Project”).
In the Moose Lake area, three high -priority drill target areas were defined by the MobileMT survey, one of which is
coincident with a previously defined gravity/EM target. These targets are located within an interpreted structural corridor
which extends north-northeast from the Cluff Lake Uranium deposits. The targets (ML -01, -02, -03) in this area are both
basement-hosted, similar to the Cluff Lake deposits, and unconformity-related (see Figure 2).5

Surprise Creek Uranium-Copper Project
The Surprise Creek Project is located 25km north -west of the Beaverlodge Uranium District, which hosts the historical
uranium mines of Gunnar and Eldorado (Ace-Fay-Verna) and is located just north of the Athabasca Basin.
A major high-resolution airborne magnetic, radiometric and VLF-EM survey completed by the 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 @ 4.37% U3O8 from 57m1, 6 and surface sampling by Thunderbird returned
assays up to 7.98% U3O8.2 The area of surface uranium mineralisation extends over a strike length of up to 500m2 (see
Figure 3).1, 2, 6
A work permit application for exploration including drilling at the Surprise Creek Fault prospect has recently been approved
by the Saskatchewan Government.
Figure 3 – Surprise Creek Project – Surprise Creek Fault prospect1, 2, 6
Many of the radiometric targets identified in the airborne survey show a strong spatial correlation with the contact
between the Archean Zemlak Domain basement rocks and the overlying younger Palaeoproterozoic aged Thluicho Lake
Group, where cross-cutting structures intersect the contact.
In addition, many of the historical copper prospects (Bob Lake, Ellis Bay, Waterloo South) are also associated with the
same contact (see Figure 4).
Historical drilling results from Bob Lake and Ellis Bay include:
• 9.1m @ 2.07% Cu and 27.3g/t Ag from surface (Bob Lake)3
• 6.6m @ 1.31% Cu from 11m (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.2,4
