The geological reports are necessary for an Annual Information Form, and to pursue a potential uplisting in the USA from the OTCQX to a Nasdaq Capital Market to complement the Company's existing listing on the TSX Venture Exchange. Both Moore and Russell are exploration-stage properties and neither of the reports includes a mineral resource estimate; however, the reports should aid in potential future resource calculations.

Together, these co-flagship projects host multiple zones of high-grade uranium mineralization across a highly prospective, largely contiguous land package in the eastern Athabasca Basin, and Skyharbour is actively advancing both assets through ongoing exploration and drilling programs. Each technical report is the culmination of previously reported and compiled historical and recent exploration data and geological information for the respective project. The reports provide a detailed description of each project, including historical and recent exploration as well as drilling results, together with recommendations for future exploration and drilling programs. All scientific and technical information contained in the technical reports has been previously disclosed by the Company, and no new material information is being reported. Skyharbour has prepared and filed these updated and independent NI 43-101 technical reports on its co-flagship Moore and Russell Lake Uranium Projects as part of its ongoing corporate development initiatives, including plans for an Annual Information Form in part to pursue an uplisting of its common shares on the Nasdaq Capital Market (“Nasdaq”). The updated technical reports, together with the Company’s Annual Information Form, are intended to ensure that current, independently prepared technical disclosure on the Company’s material uranium projects is available to support this uplisting. There can be no assurance that the Company will proceed with or complete the Nasdaq listing, or as to the timing thereof, which remains subject to, among other things, satisfaction of Nasdaq’s listing requirements and applicable regulatory approvals. No mineral resource estimate or mineral reserve estimate has been defined on either the Russell Lake Uranium Project or the Moore Uranium Project, and neither technical report includes a mineral resource estimate, a mineral reserve estimate, or any economic analysis. Accordingly, the sections of Form 43-101F1 addressing mineral resource and mineral reserve estimates, mining methods, recovery methods, project infrastructure, market studies, environmental studies, permitting, capital and operating costs, and economic analysis are not applicable to these early-stage exploration properties and have been omitted from each report. Readers are cautioned that mineral exploration is inherently uncertain, and there is no guarantee that further exploration will result in the delineation of a mineral resource or an economically viable mineral deposit. The independent NI 43-101 technical report on the Moore Uranium Project is entitled “NI 43-101 Technical Report on the Moore Property” and has a signature date of August 20th, 2026. The report was prepared by John Shmyr, B.Sc., P.Geo. of Dahrouge Geological Consulting Ltd., an independent Qualified Person as defined under NI 43-101.

Qualified Person: The technical information in this news release has been prepared in accordance with the Canadian regulatory requirements set out in National Instrument 43-101 and reviewed and approved by Serdar Donmez, P.Geo., VP Exploration for Skyharbour as well as a Qualified Person. 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-four projects covering over 682,100 hectares (1.69M 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 exploration property with high-grade uranium mineralization at the Maverick Zones. 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; Future Fuels at the Highway Project; CSE-listed Mustang Energy at the 914W Project; CSE-listed Purecore Metals at the Yurchison 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 potentially over $79 million in partner-funded exploration expenditures and over $52 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.
