2025 Exploration Program at Preston:
The program for the Preston Project will consist of a helicopter-supported diamond drilling campaign, totaling 6,000 to 7,000 metres, with up to 28 holes designed to test high-priority targets across the property at depths ranging from 200 to 350 metres. Primary drill target areas (outlined in Figure 2) include the previously untested Johnson Lake, the Canoe Lake and FSAN target. Target areas are spread throughout the project to ensure assessment credits are met across all claims, while testing perspective trends.

Drilling in the Johnson Lake area (Zone 1; Figure 2) will target a broad structural corridor initially identified in an airborne VTEM survey and subsequently refined by a ground-based ML-TEM survey in 2018 and a DC resistivity survey in 2020. Multiple parallel conductors exhibiting moderate to strong responses have been delineated across the grid. A total of 4 to 5 drill holes are planned with an average depth of 350 metres for a total of approximately 1,750 metres, contingent on results. The primary objective is to test ground conductors at structurally complex intersections which are considered highly prospective for uranium mineralization. There has been no drilling completed in the Johnson Lake grid area to date.

The Canoe Lake area (Zone 2; Figure 2) comprises nine conductive trends that remain largely untested, with only one to three historical drill holes completed on each to date. The 2025 program aims to assess high-priority targets for uranium mineralization and to further define Canoe Lake as a prospective discovery corridor within the Preston Lake Project.
A total of 6 to 12 diamond drill holes are planned, totalling approximately 1,200 to 2,400 metres, with an average hole depth of 200 metres. Six zones of interest have been identified based on the review of available airborne and ground geophysical data, characterized by gravity lows near interpreted structural breaks and crosscutting magnetic features. Structural features in the southwestern portion of the grid are of particular interest due to their orientation, which is analogous to the structural trends controlling mineralization at the PLS and Arrow uranium deposits. These targets are on strike with zones of brittle-ductile deformation and hydrothermal alteration observed in historical drilling, supporting their potential for hosting basement-hosted uranium mineralization.

The FSAN Zone (Zone 3; Figure 2) will be the most extensively tested area in the 2025 program, with both reconnaissance and direct targeting strategies to be employed. Reconnaissance drilling will consist of 3 holes totalling approximately 1,050 metres, focusing on discrete airborne EM anomalies near the intersection of prospective east-west structures. An additional 7 to 14 holes will be drilled using a more direct targeting approach for a total of 1,400 to 2,800 metres. These holes will test gravity low anomalies, areas of magnetic disruption, and sites of high geochemical response, including SGH uranium anomalies and historical surface grab samples with anomalous uranium and pathfinder element concentrations.

The West and Far West Grids (Zone 4; Figure 2) have been designated as contingency targets for the 2025 drill program. These areas encompass the western extent of the PL-1 conductive trend, where historical drilling intersected moderately to strongly graphitic, brittle-ductile fault zones with localized hydrothermal alteration. The structural complexity observed in this area enhances its prospectivity for basement-hosted uranium mineralization and warrants further investigation.
2024 Exploration Program Completed at Preston:
The 2024 field program marked the first exploration activities conducted by Orano at the Preston Project since 2020. The program included a 35.6 km ground Moving-Loop Transient Electromagnetic (ML-TEM) survey over the Preston West and Far West targets, focusing on an airborne VTEM conductor at Preston West and following up on a prior reconnaissance survey at Preston Far West.
A ground gravity survey comprising 2,295 stations was also completed over an area encompassing the FSAN and FSANE trends to help with drill target prioritization. In addition, a Spatiotemporal Geochemical Hydrocarbon (SGH) geochemical survey comprising approximately 1,100 samples was carried out during the summer of 2024. SGH is a cost-effective technique which has been successfully used to detect surficial anomalies associated with buried uranium mineralization in the Athabasca Basin.
Preston Uranium Project:
In March 2017, Skyharbour signed an option agreement with Orano (formerly AREVA Resources Inc.) that provided Orano an earn-in option to acquire a majority working interest in the 49,635-hectare Preston Uranium Project. The significant potential of the Project has been highlighted by past discoveries in the area by NexGen Energy Ltd. (Arrow deposit), Fission Uranium Corp. (Triple R deposit), and F3 Uranium Corp. (PLN discovery). Exploration at the Project has consisted of ground gravity, airborne and ground electromagnetics, radon, soil, silt, biogeochem, lake sediment, and geological mapping surveys, as well as exploratory drill programs. Over a dozen high-priority drill target areas associated with multiple prospective exploration corridors have been successfully delineated through these methodical, multi-phased exploration initiatives, which have culminated in an extensive, proprietary geological database for the project area.
Joint Venture and Strategic Partnership:
In early 2021, Orano fulfilled its earn-in option on the project by funding exploration expenditures and making the required cash payments. Upon completion of a total of CAD $4.8 million in exploration spending, a joint venture was established between Orano, Skyharbour, and Dixie Gold to advance and develop the project. Orano currently holds a 53.3% interest in the joint venture, with Skyharbour and Dixie Gold holding 25.6% and 21.1% interests, respectively.

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 thirty-six 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% 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 3 O 8 over 5.9 metres, including 20.8% U 3 O 8 over 1.5 metres at a vertical depth of 265 metres. Adjacent to the Moore Project is the Russell Lake Uranium Project, in which Skyharbour is the operator with joint-venture partner Rio Tinto. The project 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 also has joint ventures with the industry leader 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 CSE-listed Basin 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; 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 over $36 million in partner-funded 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.
