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

forty-three projects covering over 662,887 hectares (1,638,029 acres) of land. Skyharbour owns 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 explor ation property with high -grade uranium mineralization at the

Maverick Zone highlighted by 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 Moore, Skyharbour is advancing

several uranium properties within the broader Russell Lake project area with its joint venture partner

and large strategic shareholder Denison Mines. Collectively these co-flagship projects host multiple

zones of high-grade uranium mineralization across a highly prospective land package with significant

exploration upside, and the Company is actively working these assets through exploration and drilling

programs.

Skyharbour now has joint ventures with industry-leaders Denison Mines and Orano Canada Inc. at

the Russell Lake properties and the Preston project, respectively . The Company also has several

active earn-in option partners, including CSE-listed Nexus 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 Ener gy at the South Falcon East Project. In

aggregate, Skyharbour has now signed earn -in option agreements with partners that total to

potentially over $76 million in partner-funded exploration expenditures and over $42 million in cash

and share payments coming into Skyharbour, assuming that these partner companies complete the

earn-ins at their 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.
