Skyharbour Commences its 2025 Drilling Campaign with Winter Drilling Program at its Russell Lake Uranium Project, Saskatchewan

Skyharbour Resources Ltd. (TSX-V: SYH ) (OTCQX: SYHBF ) (Frankfurt: SC1P ) ("Skyharbour" or the "Company") is pleased to announce the commencement of its winter phase of diamond drilling at the 73,314 hectare Russell Lake Uranium Project ("Russell" or the "Project"). The Project is 57.7% owned by Skyharbour as operator with joint-venture partner Rio Tinto Exploration Canada Inc. ("RTEC") owning the other 42.3%. It is strategically located in the central core of the Eastern Athabasca Basin of northern Saskatchewan, with access to regional infrastructure, including an all-weather road and powerline. Skyharbour plans to complete an initial 5,000-metre diamond drilling program in 10 to 12 holes at the project, building on the successful results from the drilling campaign completed last year. The Company's geologists, along with a contracted drilling crew, are based at Skyharbour's exploration camp on the McArthur River-Key Lake haul road, situated within five kilometres of Denison Mines' Phoenix deposit at the Wheeler River Project.

Skyharbour is fully-funded for its upcoming drill programs at its co-flagship Russell Lake and Moore Uranium Projects in 2025 starting with this first phase of drilling at Russell. The Company has plans to drill approx. 16,000 – 18,000 metres in 35 – 45 holes across its co-flagship projects representing the largest annual drill campaign ever carried out by the Company.

Jordan Trimble, President and CEO of Skyharbour, stated: "We are thrilled to commence the 2025 drill campaign which will consist of 16-18,000 metres in multiple phases of drilling at Russell and Moore throughout the year. This will provide steady news flow as we follow up on the 2024 programs with the benefit of low-cost drilling and relatively shallow target depths at our co-flagship projects. This first phase of drilling at Russell will continue to test the exploration upside at the project, which hosts widespread uranium mineralization and has the geology necessary for larger, high-grade, Athabasca Basin uranium deposits."

Winter Phase of Diamond Drilling at Russell Lake:

Skyharbour has commenced its 2025 drilling program at the Russell Lake Project with plans for a first phase consisting of approx. 5,000 metres to follow up on notable recent exploration success and to test new targets developed by the geological team . The focus for this phase of drilling will be on the Fork and Sphinx targets within the broader Grayling target area, as well as the M-Zone Extension ("MZE") target and the Fox Lake Trail target. This initial winter program will consist of 10 to 12 drill holes, with most of the targets being road accessible and near the exploration camp, bringing the drill costs down. Furthermore, details on the geochemical assay results are pending from the drilling carried out in late 2024 at Russell.

The Fork target is a newly identified target to the southwest of the Grayling Zone and is on strike with Denison's M-Zone at their adjacent Wheeler River Project. Last year, high-grade uranium was discovered at the Fork target in hole RSL24-02, which returned a 2.5-metre wide intercept of 0.721% U ₃ O ₈ at a relatively shallow depth of 338.1 metres, including approx. 3.0% U ₃ O ₈ over 0.5 metres just above the unconformity in the sandstone (see news release dated July 19 ^th , 2024, titled: "Skyharbour Drills New Discovery at Russell Project with High-Grade Uranium Mineralization Up to 3.0% U ₃ O ₈ at Newly Identified Fork Zone"). This high-grade intercept is a new discovery which had very limited historical exploration due to a lack of reliable geophysical data and drill targets hampered by interference from nearby powerlines. The mineralization remains open in most directions, including along strike and up-dip, and will be a high-priority target for this drill program. The potential for basement-hosted mineralization at the Fork target remains virtually untested.

Skyharbour also plans to drill targets in the M-Zone Extension area along trend from the Grayling Zone and Denison's M-Zone at Wheeler River, where historical drilling intersected basement-hosted uranium mineralization. More recent drilling by Denison in 2020 at the M-Zone encountered uranium mineralization with significant faulting, core loss, geochemical anomalies, and radioactivity encountered in other drill holes. Like the Grayling Zone, the mineralization at the MZE target is hosted by a graphitic thrust fault within a significant magnetic low. It is also noted that cross structures associated with Denison's Phoenix and Gryphon uranium deposits potentially trend onto the Russell Lake property within the M-Zone Extension target area, further enhancing the prospectivity of this target.

The Fox Lake Trail ("FLT") area is located in the northwestern section of the Russell Lake project. This area encompasses a broad conductive corridor with a strike length exceeding 12 km, which hosts multiple parallel conductors identified by both airborne and ground geophysical surveys, subsequently confirmed by drilling, as graphitic fault zones. Limited historical drilling in the area shows significant alteration and disruption in both sandstone and basement rocks, along with elevated radioactivity and highly anomalous pathfinder geochemistry in drill core samples. These findings indicate the presence of a significant hydrothermal system in the area, which is often associated with the formation of high-grade, unconformity-type uranium deposits in the Athabasca Basin.

Russell Lake Uranium Project Overview:

The Russell Lake Project is a large, advanced-stage uranium exploration property totalling 73,314 hectares strategically located between Cameco's Key Lake and McArthur River Projects, and adjoining Denison's Wheeler River Project to the west and Skyharbour's Moore Uranium Project to the east. The northern extension of Highway 914 between Key Lake and McArthur River runs through the western extent of the property and greatly enhances accessibility, while a high-voltage powerline is situated alongside this road. Skyharbour's acquisition of a majority interest in Russell Lake creates a large, nearly contiguous block of highly prospective uranium claims totalling 109,019 hectares between the Russell Lake and the Moore uranium projects. Several notable exploration targets exist on Russell, including the Grayling Zone, the M-Zone Extension target, the Little Man Lake target, the Christie Lake target, the Fox Lake Trail target and the newly identified Fork Zone target. More than 35 kilometres of largely untested prospective conductors in areas of low magnetic intensity also exist on the Property. Skyharbour is the operator and owns a majority interest in Russell Lake, having formed a joint venture partnership with RTEC at the project.
