Skyharbour Announces Additional Uranium Property Staking Increasing Total Portfolio to Over 662,000 Hectares in the Athabasca Basin, Saskatchewan
Skyharbour Resources Ltd. (TSX-V: SYH) (OTCQX: SYHBF) (Frankfurt: SC1P) (‘Skyharbour’ or the ‘Company’), is pleased to announce that it has acquired by low-cost staking forty new prospective uranium exploration claims in Northern Saskatchewan, increasing Skyharbour’s total land package that it has ownership interest in to 662,887 hectares (1,638,029 acres) across 43 projects. The newly staked claims, which are 100% owned by the Company, add 64,913 hectares (160,403 acres) to Skyharbour’s existing holdings in and around the Athabasca Basin, home to the highest-grade uranium deposits in the world and consistently ranked as a top global mining jurisdiction by the Fraser Institute. While Skyharbour remains focused on advancing its co-flagship Russell Lake project portfolio, recently joint-ventured with Denison Mines, and its 100% owned Moore Project, these new claims will form part of the Company’s prospect generator business through which Skyharbour will seek strategic partners to advance and unlock value from these assets.

Summary of Recently Staked Properties:
Carter North:
The newly staked Carter North Project consists of ten mineral claims, nine of which are contiguous, with one standalone claim, totaling 36,393 hectares. The project is located in the western Athabasca Basin, adjacent to Cameco’s North Williams Project, approximately 35 kilometres northeast of NexGen Energy’s Arrow Deposit and 164 kilometres north of the community of La Loche. The project is underlain by approximately 800 to 965 metres of Athabasca Basin sandstones and conglomerates overlying the Tantano Domain. The property covers interpreted extensions of the Patterson Lake, Derkson and Carter conductive corridors and is located along strike to the northeast of the Arrow and Triple R deposits.

The project area has undergone a variety of historical exploration programs periodically between 1969 and 2023, consisting mostly of airborne radiometrics, EM (Input, GEOTEM, MEGATEM, ZTEM, and Mobile MT), ground gravity surveying, as well as prospecting, soil sampling, lake sediment sampling and boulder sampling. Two drill holes have been completed on the property, only one of which (BL-08-01) intersected the sandstone–basement unconformity. This hole returned 155 ppb Au over 0.5 metres in a sample collected immediately above the basal unconformity within Athabasca sandstone (SMDI 3075). This gold anomaly is considered significant, as gold enrichment can be associated with unconformity-related uranium mineralizing systems in the Athabasca Basin.
In addition, a historical lake sediment geochemical survey completed in 1980 reported a highly anomalous uranium value of 240 ppm U in sample SLB-80-69 (AF 74K02-0013), collected at a reconnaissance scale of approximately one sample per square kilometre, confirming a strong uranium anomaly on the property.
The most recent exploration work conducted on the Carter North property consisted of a MobileMT survey in 2023 by Stallion Uranium, which detected numerous basement conductors on the Carter North property, including trends interpreted as the extensions of the Patterson Lake, Carter, and Derksen trends, which are host to some of the world’s highest-grade uranium deposits to the southwest along trend, including the Arrow and Triple R uranium deposits.
Rover:
The newly staked Rover Project consists of a single claim totalling approximately 793 hectares located approximately 40 kilometres east of Cameco’s McArthur River Mine, 31 kilometers southeast of the Cigar Lake Mine, and 68 kilometers west of the community of Wollaston Lake. Historical exploration extended over a long-time span, from the late 1960’s through the early 1990’s, with most of the work being completed in the 1970’s. The property is located within the Athabasca Basin and is underlain by a shallow cover of Athabasca Group Sandstones, which in turn overly the Paleoproterozoic metasedimentary rocks of the Wollaston Supergroup.

In 1994, Cameco conducted two ground prospectivity surveys on the property, targeting Pb-Zn-Ni anomalies. More recent work included airborne geophysics (VTEM and Horizontal Magnetic Gradiometer surveys) conducted by Phalanx Disposition Ltd. on behalf of Athabasca Uranium Inc. in 2013. In addition, Abasca Minerals and Athabasca Uranium completed a 455 line-kilometer HeliFALCON Gravity survey over two grids on the property. One drill hole (4675-001-79) was completed on the property in 1979, intersecting 133.7m of Athabasca sandstone, with a total depth of 151.5m. Aside from this single hole, the property remains largely untested by diamond drilling.
East Dufferin:
The East Dufferin Project consists of a single newly staked claim totalling 1,451 ha and is located immediately south of the southern margin of the Athabasca Basin in northern Saskatchewan, approximately 4 km west of Skyharbour’s South Dufferin project, which is currently under option to UraEx Resources. The project is underlain by Paleoproterozoic metasedimentary gneisses of the Mudjatik Domain overlying Archean granitoid gneisses and is situated immediately to the east of the Virgin River Shear Zone, which hosts the Centennial Zone uranium deposit approximately 26 km to the north of the East Dufferin project.
East Dufferin Project Map:
https://www.skyharbourltd.com/_resources/images/SkyHarbour_EastDufferin.jpg
Exploration work on the property between 1969 and 2010 included a variety of airborne EM, gravity, magnetic, and radiometric surveys, as well as ground magnetic and EM surveys, surficial geochemical sampling (including lake and stream water, lake sediment and vegetation sampling), prospecting and geological mapping. The most recent work consisting of ZTEM and airborne full tensor gravity (FTG) surveys completed by JNR Resources in 2009 and 2010. Prior exploration identified a broad zone of increased conductivity and moderate magnetic activity associated with a magnetic linear feature on the East Dufferin project, situated between strong EM conductors located just off the property to the north and east.
Brustad Project:
The Brustad project consists of one newly staked mineral claim totaling 791 hectares, located approximately 21 km east of Skyharbour’s South Dufferin property. The property is located just south of the southern Athabasca Basin margin in the Mudjatik Domain of northern Saskatchewan, with the basement rocks underlying the property including Archean granitoid gneisses and subordinate Paleoproterozoic metasedimentary gneisses.

Historical exploration on the property includes airborne electromagnetics (AFMAG, MobileMT, GeoTEM, Input), magnetic and radiometric surveys, and limited prospecting, mapping, vegetation, and lake sediment sampling. No drilling has taken place on the project, but recent airborne geophysical surveys identified a north-south trending EM conductor running alongside the western edge of the property adjacent to a NW trending aeromagnetic low.
914 and Elevator Projects:
The 914 and Elevator Projects now comprise a total of thirteen mineral claims forming two contiguous claim blocks, covering 13,785 hectares. The 914 Project consists of seven contiguous claims totaling 4,031 hectares including four newly staked claims totaling 2,898 hectares. The Elevator Project consists of six contiguous claims totaling 9,754 hectares including four newly staked claims totaling 1,742 hectares. Both projects are located 35 to 55 km south of Cameco’s Key Lake Operation. The 914 Project lies 1 km east of Provincial Highway 914, while the Elevator Project is 12 km east of Highway 914, which provides access to the properties from southern Saskatchewan.
914 and Elevator Project Map:
https://www.skyharbourltd.com/_resources/images/SkyHarbour_914.jpg
Geological mapping and prospecting completed on and in the vicinity of the properties indicate that they are underlain by Wollaston Supergroup metasedimentary gneisses and Archean granitic to tonalitic gneisses of the Western Wollaston Domain, a geological setting known for basement-hosted, unconformity-related uranium mineralization elsewhere in the Athabasca Basin.
Extensive exploration was carried out on and around the properties during the 1970’s, including magnetic, gravity, and electromagnetic surveys, geological mapping, prospecting, and boulder and sediment sampling. Modern work has been limited, consisting of partial airborne VTEM coverage, light ground prospecting, and lake sediment sampling. The newly staked claims are positioned along the margins of regional-scale fold structures, with recent airborne magnetic data revealing additional geological complexity not captured in earlier mapping. Multiple uranium and REE showings exist in the surrounding area around the claims. The same basement rocks found on the 914 and Elevator Projects host unconformity-related and pegmatite-hosted uranium, thorium, and REE mineralization, and fault-hosted flake graphite elsewhere in the region.
Pendleton:
The Pendleton Project consists of four non-contiguous mineral claims totalling 5,338 ha including one recently staked claim totalling 1,448 ha, and is located approximately 70 km southeast of Cameco’s Key Lake Operation and 114 km northwest of the community of Southend. The Pendleton project lies along the Needle Falls Shear Zone at the boundary between the eastern Wollaston Domain and the western Peter Lake Domain. It is underlain by the Wollaston Supergroup metasedimentary rocks including psammopelitic, pelitic, and graphitic pelitic gneisses, as well as mylonitic and cataclastic rocks of the Needle Falls Shear zone and Archean granitoid gneisses, diorites, and gabbros of the Johnson River Inlier and Swan River Complex.
Pendleton Project Map:
https://www.skyharbourltd.com/_resources/images/SkyHarbour_Pendleton.jpg
The initial exploration work on the project was conducted in the 1970’s and 1980’s, consisting of airborne magnetic, radiometric, and EM surveys, as well as prospecting and geochemical sampling. Additional modern exploration included an airborne GEOTEM survey in 2004, ground prospecting and geochemical sampling. A single drill hole (PL-003) completed following the 2007 HLEM survey intersected faulted and sheared graphitic pelitic gneiss and returned anomalous concentrations of several pathfinder elements. The project is considered prospective for basement-hosted, unconformity-related uranium deposits, as well as pegmatite-hosted U-Th-REE mineralization and/or sediment-hosted Pb-Zn-Cu mineralization.
Yurchison:
The Yurchison Project has been expanded through the staking of sixteen additional mineral claims totaling 16,966 hectares, increasing the project’s total land package to 35,029 hectares. The expanded project consolidates the former Yurchison and Spence properties into a single land package. The Yurchison Project is located approximately 75 to 85 km south of Cameco’s Rabbit Lake operation, with Highway 905 located within 1 km of the westernmost claims. The project is underlain by Wollaston Supergroup metasedimentary gneisses, including psammopelitic to pelitic gneisses, graphitic pelitic gneisses adjacent to Archean granitic gneisses in the Eastern Wollaston Domain.
Yurchison Project Map:
https://www.skyharbourltd.com/_resources/images/SkyHarbour_Yurchison.jpg
The project area has seen significant historical exploration including airborne electromagnetic, magnetic, and radiometric surveys, as well as ground magnetic, EM, IP, and gravity surveys, prospecting, geological mapping, geochemical sampling, and drilling. The drilling was primarily conducted between the 1960’s and 1980’s with additional work completed in the mid-1990’s and 2000’s. The historical exploration on the eastern side of the property was largely focused on exploring SEDEX-style Pb-Zn mineralization following the discovery of the historic George Lake Pb-Zn Deposit adjacent to the property.
The majority of the work on the property was completed before 2000, with minimal follow-up since, and most of the property remains underexplored. There are several uranium, molybdenum, and thorium showings on the project, which remains highly prospective for both basement-hosted uranium, pegmatite-hosted U-Th-REE, and sediment-hosted Cu-Pb-Zn mineralization. The most recent work on the property included airborne EM (VTEM and VLF-EM), magnetics, and radiometrics surveys flown in 2022 and 2023.
Tarku Project:
The Tarku Project consists of three claims, totalling 8,262 ha, including one newly staked claim covering 2,384 ha, and is located adjacent to Skyharbour’s South Dufferin Project, which is currently under option to UraEx Resources. The property covers the southern extension of the Virgin River Shear Zone, which hosts high-grade uranium mineralization at Cameco’s Dufferin Lake zone, approximately 32 kilometres to the north, with drill results of 1.73% U3O8 over 6.5 metres, and the Centennial deposit, approximately 47 kilometres to the north, which includes historical drill intersections of 8.78% U3O8 over 33.9 metres.
Tarku Project Map:

Historical exploration on the property includes airborne EM, magnetic, and radiometric surveys, lake water and sediment sampling, prospecting, ground-truthing of anomalies, geological mapping, and diamond drilling. The project offers strong potential for basement-hosted, unconformity-related uranium mineralization along the Virgin River Shear Zone trend.
South Dufferin:
The South Dufferin Project has been expanded through the staking of one additional mineral claim totaling 49 hectares, increasing the project’s total land package to 39,398 hectares across 25 claims. The South Dufferin project is located immediately south of the Athabasca Basin in northern Saskatchewan and covers the southern extension of the Virgin River Shear Zone, which hosts known high-grade uranium mineralization at Cameco’s Dufferin Lake zone approximately 13 kilometres to the north and Cameco’s Centennial deposit approximately 25 kilometres to the north. In October of 2024, Skyharbour entered into an option agreement with a private company, UraEx Resources Inc., whereby UraEx may acquire up to a 100% interest in the Company’s South Dufferin Uranium Project.
South Dufferin Property Map:
https://www.skyharbourltd.com/_resources/images/SkyHarbour_SouthDufferin.jpg
Historical exploration work on South Dufferin consists of airborne EM, magnetic, gravity and radiometric surveys, lake water and sediment sampling, prospecting and ground-truthing of airborne anomalies, geological mapping, and diamond drilling. Some of the historical drill holes intersected elevated uranium with locally anomalous base metal and boron concentrations as well as significant clay alteration.
Exploration potential exists for basement-hosted uranium mineralization associated with the Dufferin Lake fault and parallel faults within the Virgin Lake Shear zone. With numerous mineralized showings to the north of the project, exploration efforts at South Dufferin have advanced the project to a discovery-ready state. The project is drill-ready with several prospective targets warranting follow up work, and most recently underwent diamond drilling by Skyharbour’s partner UraEx in the summer of 2025.
