Skyharbour’s Partner Mustang Energy Corp. Announces Results of TDEM Survey Over the
914W Property
Vancouver, BC - Skyharbour Resources Ltd . (TSX-V: SYH) (OTCQX: SYHBF) (Frankfurt:
SC1P) (“Skyharbour” or the “Company”) is pleased to announce that partner company Mustang
Energy Corp. (“Mustang”) received the results of a high resolution HTDEM survey at the 914W
Uranium Project (the “Project”), totaling 136 line -kms. The Project has road access and is in a
prospective region known for its mineral potential south of the Athabasca Basin. The 914W TDEM
survey successfully defined a well-developed conductive zone within the project. The geometry and
strength of the anomaly are consistent with graphitic basement rocks or fault-bound alteration zones,
both favorable for unconformity -type uranium mineralization. Mustang Energy may acquire a 75%
interest in the Project by issuing common shares having an aggregate value of CAD $480,000,
making aggregate cash payments of $275,000 to Skyharbour, and incurring an aggregate of
$800,000 in exploration expenditures on the property over a three-year period.

The Xcite™ helicopter-borne Time Domain Electromagnetic (TDEM) survey was flown by Axiom
Exploration Group Ltd. over the Project, covering approximately 136 line -km. The survey
simultaneously collected electromagnetic, magnetic, and radiometric data to map conductive,
magnetic, and radiometric variations related to prospective uranium-bearing structures. The survey
was flown in addition to Mustang’s nearby Spur project TDEM survey.
Early-time channels (0.014–0.045 ms) show strong, high -amplitude EM responses along the east -
central portion of the 914W block, indicating shallow conductive zones near surface. This conductor
persists through mid-to-late time channels (0.12–0.56 ms) and may represent graphitic horizons or
fault-controlled alteration zones, a key uranium pathfinder feature in the Athabasca Basin margin
setting. The intensity and continuity of the anomaly diminish slightly with later decay times, consistent
with a discrete subsurface conductor rather than surficial noise.

The inversion modelling from 50 m to 350 m depth shows consistent conductive features. From 50
– 150 m the depth slices show a strong, laterally continuous conductive zone trending east-northeast
across the east-central portion of the property. The 250 to 350 m depth slices show the conductivity
anomaly persists at depth.
2025 914W Soil Sampling Results:
A one-week prospecting and soil sampling program was carried out on claim 914W in May of 2025.
In total, 25 rock samples and 142 soil samples were collected. The soil sampling focused on the
northwest corner of the property immediately south of the Scurry Rainbow E Zone and the Don Lake
Trenches where no outcrop exposure is present. Rock sampling was limited by the scarcity of
exposed outcrop across the property.

Although the program did not identify any new significant discoveries, particularly in the southern
portion of the Project, the northern soil grid returned anomalous uranium values. In this program, five
soil samples from the southern portion of the grid exceeded 4 ppm U, which would be considered
slightly elevated.
Prospecting efforts did not confirm elevated uranium values in the southwestern part of the grid,
likely due to limited outcrop exposure. However, anomalous uranium values were identified in the
northeastern portion of the soil grid, including a granitic gneiss sample that returned 42.3 ppm U.
Sampling Methods:
Samples were submitted to SRC Laboratories in Saskatoon, SK, for analysis. Both rock and soil
samples were tested using ICP-MS with four-acid digestion, ICP total four-acid digestion, and U₃O₈
assays by ICP reported in weight percent.
Horizon A soil samples were collected by removing surface vegetation with a trowel and sampling
the uppermost layer of topsoil. Rock samples were taken from exposed basement boulders or
granitic outcrops that returned elevated counts per second (cps) readings.

914W Property Summary:
The 914W Project consists of one claim covering 1,260 hectares approximately 48 km southwest of
Cameco’s Key Lake Operation. Highway 914 runs through the western edge of the project, providing
excellent access for exploration. Historical geological mapping of the property and the surrounding
area has shown that the project is predominantly underlain by prospective Wollaston Supergroup
pelitic and psammitic to arkosic gneisses of the Western Wollaston Domain, which hosts significant
unconformity-related uranium mineralization in the Athabasca Basin as well as pegmatite -hosted
uranium mineralization elsewhere in the Wollaston Domain.
Despite the project’s proximity to Highway 914 and prospective geology, the project has seen limited
modern exploration work. The earliest work on the 914W property included airborne EM and
magnetic surveys and ground geological reconnaissance in 1968 -1970, lake water and sediment
sampling in 1976, ground VLF -EM, magnetic, and radiometric surveys, geological map ping,
trenching, as well as sampling on the project and surrounding areas. Immediately to the north of the
914W property, prospecting led to the discovery of the Scurry Rainbow Zone E (SMDI1961) and the
Don Lake Trenches (SMDI 1983), where up to 1,288 ppm U was encountered in drill hole ML -1
(SMDI1961) in a pyroxene-rich unit, and surface prospecting revealed up to 0.64% U3O8 in a trench
at Don Lake Zone E (SMDI 1983). More recently, the project has seen airborne geophysical
coverage by helicopter-borne VTEM (southern half) in 2005 and Tempest TDEM (northern half) in
2007, with prospecting, geological mapping, rock/sediment sa mpling and lake sediment sampling
occurring on the project and surrounding areas in 2005 -2007. The project remains underexplored
and prospective for unconformity-related and pegmatite-hosted uranium and REE’s.

About Skyharbour Resources Ltd.:
Skyharbour holds an extensive portfolio of uranium exploration projects in Canada's Athabasca
Basin and is well positioned to benefit from improving uranium market fundamentals with interest in
thirty-seven projects covering over 616,000 hectares (over 1.5 million acres) of land. Skyharbour has
acquired from Denison Mines, a large strategic shareholder of the Company, a 100% interest in the
Moore Uranium Project, which is located 15 kilometres east of Denison's Wheeler River project and
39 kilometres south of Cameco's McArthur River uranium mine. Moore is an advanced -stage
uranium exploration property with high -grade uranium mineralization in several zones at the
Maverick Corridor. Adjacent to the Moore Project is the Russell Lake Uranium Project, in which
Skyharbour is operator with joint -venture partner RTEC. The project hosts widespread uranium
mineralization in drill intercepts over a large property area with exploration upside potential. The
Company is actively advancing these projects through exploration and drilling programs.
Skyharbour also has joint ventures with industry leader Orano Canada Inc., Azincourt Energy, and
Thunderbird Resources at the Preston, East Preston, and Hook Lake Projects, respectively. The
Company also has several active earn-in option partners, including CSE-listed Basin Uranium Corp.
at the Mann Lake Uranium Project; TSX-V listed North Shore Uranium at the Falcon Project; UraEx
Resources at the South Dufferin and Bolt Projects; Hatchet Uranium at the Highway Project; CSE -
listed Mustang Energy at the 914W Project; and TSX-V listed Terra Clean Energy at the South Falcon
East Project.
In aggregate, Skyharbour has now signed earn-in option agreements with partners that total to over
$36 million in partner-funded exploration expenditures, over $20 million worth of shares being issued,
and $14 million in cash payments coming into Skyharbour, assuming that these partner companies
complete their entire earn-ins at the respective projects.
Skyharbour's goal is to maximize shareholder value through new mineral discoveries, committed
long-term partnerships, and the advancement of exploration projects in geopolitically favourable
jurisdictions.
