NEWS RELEASE

Skyharbour Appoints Athabasca Basin Veteran, Serdar Donmez, as Vice President of

Exploration

Vancouver, BC - Skyharbour Resources Ltd.’s (TSX-V: SYH) (OTCQX: SYHBF) (Frankfurt:

SC1P) (the “Company”) is pleased to announce the appointment of Serdar Donmez, a recognized

geoscientist with decades of experience in uranium exploration and development, as Vice President

of Exploration. Mr. Donmez will be working with the rest of Skyharbour’s geological team based in

Saskatoon.

As a highly experienced geoscientist with nearly two decades of expertise in uranium exploration

and development, Mr. Donmez has played an active role in numerous grassroots and advanced

uranium exploration projects in northern Saskatchewan and Zambia. Mr. Donmez has an

Engineering Degree in Geology and is a registered Professional Geoscientist with the Association

of Professional Engineers and Geoscientists of Saskatchewan.

During his 17-year tenure at Denison Mines Corp., Mr. Donmez was pivotal in advancing numerous

uranium exploration and development projects. He was involved in various capacities with the

Phoenix and Gryphon uranium deposits on Denison’s Wheeler River project, from initial discovery to

the completion of the Feasibility Study in 2023. As Resource Geology Manager, he was integral to

the development of mineral resource estimates and NI 43-101 technical reports for several advanced

exploration projects in the A thabasca Basin. Additionally, he was part of a team exploring the

application of in-situ recovery mining techniques for high-grade uranium deposits in the Athabasca

Basin.

Mr. Donmez’s extensive experience in advancing Athabasca Basin uranium projects, particularly his

work at the Phoenix and Gryphon deposits at Wheeler River, ali gns very well with Skyharbour's

exploration and drilling initiatives at its co-flagship adjacent Russell and Moore Lake projects. Recent

drilling this year at both projects has identified high-grade, multi-percent sandstone-hosted uranium

mineralization. With a fully -funded, 2,500m drill program already underway at Moore and an

additional 4,000-5,000m drilling program scheduled for Russell this fall, Mr. Donmez's expertise will

be invaluable in advancing these projects and unlocking further value going forward.

Mr. Donmez’s deep understanding of the discovery process in the Athabasca Basin along with his

experience in implementing innovative exploration and development techniques positions him to play

a critical role in advancing both projects as the Company continues to make new discoveries and

expand its resource base.

Jordan Trimble, President and CEO of Skyharbour stated: “Serdar brings an incredible wealth of

experience to the Skyharbour technical team and has specific exploration and development

expertise in the southeastern portion of the Athabasca Basin where our core projects are located.

His many years of work at Wheeler River will prove to be invaluable at our Russell and Moore projects

as we look to generate and expand on new discoveries as well as delineate high grade uranium

resources in similar geological settings. The ability to attract such a talented and seasoned individual

to the team is a testament to our portfolio of projects and multi-faceted strategy in the Athabasca

Basin where Serdar will also be working to help manage and expand our prospect generator

business.”

Furthermore, in his most recent role, Mr. Donmez served as Vice President of Exploration at 92

Energy Ltd. until its acquisition by Atha Energy Corp. in April 2024. Following the acquisition, he

transitioned to the role of Director of Exploration, where he helped in target generation for drilling

programs at Atha’s Angilak and Gemini projects in Nunavut and northern Saskatchewan.

Serdar Donmez, Vice President of Exploration of Skyharbour , stated: “I am thrilled to join the

Skyharbour team, which has a proven track record in developing and advancing high-profile uranium

exploration projects in the Athabasca Basin. Skyharbour’s impressive portfolio includes flagship

projects like Moore Lake and Russe ll Lake, where notable high -grade uranium mineralization has

been discovered in multiple zones. I look forward to leading the technical team in advancing our

exploration initiatives and demonstrating the substantial growth potential that exists within our

projects.”

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 twenty -

nine projects, ten of which are drill-ready, covering over 580,000 hectares (over 1.4 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 at the

Maverick Zone that returned drill results of up to 6.0% U 3O8 over 5.9 metres including 20.8%

U3O8 over 1.5 metres at a vertical depth of 265 metres. Adjacent to the Moore Uranium Project is

Skyharbour’s recently optioned Russell Lake Uranium Project from Rio Tinto, which hosts several

high-grade uranium drill intercepts over a large property area with robust exploration upside potential.

The Company is actively advancing these projects through exploration and drill programs.

Skyharbour has joint -ventures with industry -leader Orano Canada Inc., Azincourt Energy and

Thunderbird Resources (previously Valor) at the Preston, East Preston and Hook Lake Projects,

respectively. The Company also has several active earn -in option partne rs including: CSE -listed

Basin Uranium Corp. at the Mann Lake Uranium Project; CSE -listed Medaro Mining Corp. at the

Yurchison Project; North Shore Uranium at the Falcon Project; and TSX -V listed Tisdale Clean

Energy at the South Falcon East Project which is host to the Fraser Lakes Zone B Uranium and

Thorium Deposit. In aggregate, Skyharbour has now signed earn-in option agreements with partners

that total to over $33 million in partner -funded exploration expenditures, over $27 million worth of

shares being issued and over $20 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.
