Skyharbour Resources Ltd. (TSX-V: SYH ) (OTCQX: SYHBF ) (Frankfurt: SC1P ) (the "Company") is pleased to announce plans for an upcoming drill program at its recently optioned 73,294 hectare Russell Lake Uranium Project strategically located in the central core of the Eastern Athabasca Basin of northern Saskatchewan. Skyharbour is planning 5,000 metres of diamond drilling in ten to twelve holes over the next several months at Russell with mobilization and commencement within the next few weeks. Following the initial phase of drilling at Russell Lake, the Company will move the drill rig over to its adjacent 100% owned, 35,705 hectare high-grade Moore Uranium Project to complete a planned 3,000 metres of drilling in eight to ten holes. The combined 8,000 metre winter drill campaign across the company's core projects is fully funded and permitted with the geologists and drilling crews working out of the exploration camp at the Russell Lake Project, located along the road servicing Cameco's McArthur River Uranium Mine.

Jordan Trimble, President and CEO of Skyharbour, stated: "The upcoming commencement of our winter diamond drill campaign at both our Russell Lake and Moore Uranium Projects marks the first time Skyharbour will be simultaneously co-advancing these two core projects. This fully funded, 8,000 metre drill campaign will provide ample news flow well into the year as we advance the projects using systematic and proven exploration methodologies coupled with new geological models and targeting strategies. We are confident in the discovery potential and exploration upside at both projects given the high-grade mineralization in historical drill holes along with the many highly prospective target areas hosting the geology necessary for high-grade uranium deposition. We will also be carrying out infill and definition drilling at the high-grade zones at Moore along the Maverick Corridor."

"Skyharbour will have substantial additional news flow and catalysts from its prospect generator business consisting of partner companies advancing some of our other projects throughout the Athabasca Basin. Over the next year, the Company is anticipating the largest combined drilling and exploration programs at its primary projects of Russell and Moore, as well as at its partner-funded projects of Preston, East Preston, Mann Lake, Yurchison, Falcon, and South Falcon East."

Upcoming Winter Diamond Drilling Program at Russell Lake:

Skyharbour will soon initiate its 2024 Exploration Program at the Russell Lake Project, drilling an initial 5,000 metres to follow up on notable historic exploration and findings and test new targets developed by the geological team . Of particular interest for this drilling program will be the Grayling East and Fork targets within the broader Grayling target area as well as the M-Zone Extension target. This initial drill program will total 5,000 metres in ten to twelve drill holes with all targets being road accessible and near the exploration camp.

At the Grayling East target, additional drill testing of the eastern extent of the 2,200 m long, 100 m thick sub-parallel Grayling conductor and associated thrust fault is planned in areas of broadly spaced drill coverage and prospective geophysics and geology. In this area, several conductors are present within a broad magnetic low, and limited historical drilling encountered intervals of significant structural disruption, highly prospective alteration within the sandstone and underlying basement, with local pathfinder element enrichment associated with faulting and graphitic intervals. Further review of the geophysical and geological data from this area suggests that the historical holes may not have hit the main Grayling thrust, instead intersecting splays of the thrust and/or parallel conductors to the south of the main thrust fault. An initial three to four holes, totalling 2,000 m, are planned to test newly developed targets along the Grayling thrust in this area.

Grayling East and Fork Drill Targets:

The Fork target is a newly identified target to the west of the Grayling Zone and on-strike of Denison's M-Zone target at their adjacent Wheeler River Project, which has seen renewed interest by Denison in recent years. The target consists of a series of northeast striking and bifurcating conductive trends proximal to and related to a northeast trending magnetic low, with a prominent north-trending lineament associated with the McDougall Lake fault also running through the area. Notable resistivity and gravity targets in conjunction with anomalous geochemistry and prospective structure and alteration within the two historical drill holes in this area make for a compelling target. Three angled holes, totalling 1,500 m are planned for this area as part of the 2024 winter drill program.

M-Zone Extension Drill Targets:
https://www.skyharbourltd.com/_resources/images/20240110-M-ZoneExtensionTargetsRussellLake.jpg

Skyharbour has selected additional drill targets in the M-Zone Extension area, along trend from the Grayling Zone and Denison's M-Zone, where historical drilling intersected basement hosted uranium (up to 0.70% U3O8 over 5.8 m at 374.0 m depth). More recent drilling by Denison in 2020 at the M-Zone encountered additional uranium mineralization with significant faulting, core loss, geochemical anomalies, and radioactivity encountered in other drill holes. Like the Grayling Zone, the mineralization 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 trend onto the Russell Lake property within the M-Zone Extension target area, further enhancing the prospectivity of this target. Three to four holes, totalling 1,500 metres are planned at the M-Zone Extension target on the Russell Lake Project.

Upcoming Winter Diamond Drilling Program at Moore:

Skyharbour will conduct a second phase of drilling consisting of 3,000 metres at its high-grade Moore Project upon completion of the drilling at Russell Lake. Skyharbour plans to carry out infill and expansion drilling at the high-grade Maverick Corridor as well as to test several regional targets including the Grid Nineteen target area. This second phase of drilling will total 3,000 metres in eight to ten drill holes.

Drilling at the Maverick Corridor will focus on identifying new trends and extensions within untested portions of its 4.7 kilometre strike length. Additional drilling is planned within the Maverick Main and East Zones to concentrate on refinement and expansion of the currently identified mineralized zones. The Maverick Main Zone is characterised by basement- and unconformity-hosted mineralization, with a best interval drilled previously by Skyharbour of 6.0% U ₃ O ₈ over 5.9 metres at 265 metres depth including 20.8% U ₃ O ₈ over 1.5 metres in hole ML-199 and historical results of 4.03% eU ₃ O ₈ over 10 metres, including 20% eU ₃ O ₈ over 1.4 metres at a depth of 265.0 metres in hole ML-61. At the Maverick East Zone Skyharbour previously drilled a high-grade uranium intercept of 1.79% U ₃ O ₈ over 11.5m at 270.0 metres depth, including 4.17% U ₃ O ₈ over 4.5 metres and 9.12% U ₃ O ₈ over 1.4 metres in hole ML-202. A total of four to six holes totalling 1,500 to 1,800 metres of drilling are planned for the Maverick Main and East Zones as well as at other targets on the Maverick Structural Corridor.

Drilling on regional targets at the Moore Project will consist primarily of drill testing the Grid Nineteen area, where the Slice Pond Conductor and accompanying structural zone has been confirmed by drilling over a strike length of 800 metres to date. The Slice Pond target is typified by structurally disrupted, altered, and geochemically anomalous sandstone and basement rocks, including variably graphitic pelitic gneisses, along with a significant unconformity offset and thrust wedge. All holes drilled to date have intersected highly encouraging graphitic and sulphide bearing basement lithologies accompanied by prospective alteration and anomalous levels of B (≤1290 ppm), Th (≤445 ppm), Ni (≤500 ppm), V (≤350 ppm), and U (≤421 ppm). A notable intercept of 0.05% U ₃ O ₈ over 1.0 metre occurs well into the basement in previously drilled hole ML21-07 on the Slice Pond Conductor. The unconformity intercept of the mineralized structure is still untested. Composite geochemical sampling in the second hole on this conductor, previously drilled hole ML21-09, returned samples highly enriched in U (≤7.5 ppm U _partial ) and B (≤161 ppm) over a broad 70 metre interval in the sandstone. A total of four to five holes are anticipated to be drilled at the Grid Nineteen target area as part of the winter drill program at Moore.

Russell Lake Uranium Project Overview:

The Russell Lake Project is a large, advanced-stage uranium exploration property totalling 73,294 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 the Key Lake Mill and the McArthur River Mine runs through the western extent of the Property and greatly enhances accessibility, with a high-voltage powerline also situated alongside the road. There is a fully permitted exploration camp on the Project suitable for over thirty people located on the highway, within 5 kilometres of Denison's Phoenix deposit. Skyharbour's acquisition of Russell Lake creates a large, nearly contiguous block of highly prospective uranium claims totalling 108,999 hectares between the Russell Lake and the Moore uranium projects.

There has been a meaningful amount of historical exploration carried out at Russell Lake, however most of it was conducted before 2010 prior to the discovery of several major deposits in and around the Athabasca Basin. The Property has been the subject to greater than 95,000 metres of drilling in over 230 drill holes prior to Skyharbour's maiden drill program, with most of this drilling comprising of widely spaced exploratory and reconnaissance drilling. The Property's claims are in good standing for 2-22 years, with significant assessment credits built-up from previous exploration programs.

Several notable exploration targets exist on the property including the Grayling Zone, the M-Zone Extension target, the Little Man Lake target, the Christie Lake target, and the Fox Lake Trail target. More than 35 kilometres of largely untested prospective conductors in areas of low magnetic intensity also exist on the Property. A total of 9,595 metres of drilling in 19 holes was drilled in three phases during 2023 by Skyharbour at Russell Lake. Uranium mineralization was intersected in the majority of holes at the Grayling Zone over a strike length exceeding one kilometre. Drill hole RSL23-01 intersected one of the best ever drill results from the project, returning a 5.9 metre wide intercept of 0.151% U ₃ O ₈ at a depth of 338.4 metres, which includes 1.0 metres of 0.366% U ₃ O ₈ at 343.3 metres depth within a thrust wedge.

Moore Uranium Project Overview:

In June 2016, Skyharbour secured an option to acquire Denison Mine's Moore Uranium Project, on the southeastern side of the Athabasca Basin, in northern Saskatchewan and has fulfilled its earn in. The project consists of 12 contiguous claims totaling 35,705 hectares located 42 kilometres northeast of the Key Lake mill, approx. 15 kilometres east of Denison's Wheeler River project, and 39 kilometres south of Cameco's McArthur River uranium mine. Unconformity-type uranium mineralization was discovered on the Moore Project at the Maverick Zone in April 2001. Historical drill highlights include 4.03% eU ₃ O ₈ over 10 metres, including 20% eU ₃ O ₈ over 1.4 metres, in ML-161. In 2017, Skyharbour announced drill results of 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, in hole ML-199. In addition to the Maverick Zone, the project hosts other mineralized targets with strong discovery potential which the Company plans to test with future drill programs. The project is fully accessible via winter and ice roads which simplifies logistics and lowers costs. Large proportions of the property are accessible in the summer as well.

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 twenty-five projects, ten of which are drill-ready, covering over 520,000 hectares (over 1.2 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 Uranium Project is Skyharbour's recently optioned Russell Lake Uranium Project from Rio Tinto, which hosts historical 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 has joint-ventures with industry-leader Orano Canada Inc. and Azincourt Energy at the Preston and East Preston Projects, respectively, whereby Orano and Azincourt earned majority interests in the projects through exploration expenditures, cash payments and share issuances. Skyharbour also has several active earn-in option partners including: ASX-listed Valor Resources at the Hook Lake Uranium Project; CSE-listed Basin Uranium Corp. at the Mann Lake Uranium Project; CSE-listed Medaro Mining Corp. at the Yurchison Project; Yellow Rocks Energy, a private Australian entity, at the Wallee and Usam Island projects; North Shore Energy Metals at the South Falcon Project; and TSX-V listed Tisdale Clean Energy at the South Falcon East Project which is host to the Fraser Lakes Zone B Uranium and Thorium Deposit.

Collectively, Skyharbour has now signed earn-in option agreements with partners that total to over $37 million in partner-funded exploration expenditures, over $28 million worth of shares being issued and over $19 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.
