SKYHARBOUR'S PARTNER COMPANY MUSTANG ENERGY COMMENCES FIELD PROGRAM AT 914W URANIUM PROJECT LOCATED IN THE ATHABASCA BASIN, SASKATCHEWAN

Skyharbour Resources Ltd. partner company Mustang Energy Corp. has commenced its 2025 field exploration program at the 914W uranium project, located in Athabasca basin region. Mustang Energy may acquire a 75-per-cent interest in the project by issuing common shares having an aggregate value of $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 field program at the project will involve surface prospecting activities, including detailed rock and soil sampling, aimed at identifying zones of mineralization and alteration across target areas. Results from this phase of exploration are expected to inform further exploration efforts, including geophysical surveys and drilling in future phases. The program marks a step forward in Mustang's strategy to advance projects through systematic exploration.

"We're excited to launch our first field program of the summer at 914W," said Nick Luksha, chief executive officer of Mustang Energy. "The project area has encouraging geological features and our upcoming work is designed to generate meaningful results that will guide the next phases of exploration."

914W property summary

The 914W project consists of one claim covering 1,260 hectares approximately 48 kilometres 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 (electromagnetic) and magnetic surveys and ground geological reconnaissance in 1968 to 1970, lake water and sediment sampling in 1976, ground VLF-EM (very-low-frequency electromagnetic), magnetic and radiometric surveys, geological mapping, 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 parts per million (ppm) uranium (U) was encountered in drill hole ML-1 (SMDI1961) in a pyroxene-rich unit and surface prospecting revealed up to 0.64 per cent U3O8 in a trench at Don Lake zone E (SMDI 1983). More recently, the project has seen airborne geophysical coverage by helicopter-borne VTEM (versatile time-domain electromagnetic) (southern half) in 2005 and Tempest TDEM (time-domain electromagnetic) (northern half) in 2007, with prospecting, geological mapping, rock/sediment sampling and lake sediment sampling occurring on the project and surrounding areas in 2005 to 2007. The project remains underexplored and prospective for unconformity-related and pegmatite-hosted uranium and REEs (rare earth elements).

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 36 projects covering over 614,000 hectares (over 1.5 million acres) of land. Skyharbour has acquired from Denison Mines, a large strategic shareholder of the company, a 100-per-cent 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 leaders 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: Canadian Securities Exchange-listed Basin Uranium Corp. at the Mann Lake uranium project; TSX Venture Exchange-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-financed 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.

We seek Safe Harbor.
