Moore Uranium Project History and 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 totalling 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 style uranium mineralization was discovered on the Moore Project at the Maverick Zone in April 2001. Historical drill highlights include 4.03% eU3O8 over 10 metres including 20% eU3O8 over 1.4 metres, and in 2017, Skyharbour announced drill results including 6.0% U3O8 over 5.9 metres including 20.8% U3O8 over 1.5 metres at a vertical depth of 265 metres. 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, with large proportions of the property are accessible in the summer as well.
Since 1969, the property has undergone episodic exploration by several companies including Noranda, AGIP, BRINEX, Cogema, Kennecott/JNR Resources and IUC/Denison. In April of 2000 the Maverick Zone was discovered and in the fall of 2003, International Uranium Corporation, who then merged with Denison, optioned 75% of the property from JNR and took over operatorship. Subsequently, Denison acquired the remaining 25% interest from JNR for an undivided 100% in February of 2013, when it acquired all of the outstanding shares of JNR. Exploration programs carried out on the project lands include an assortment of airborne and ground electromagnetic and magnetic surveys, ground gravity, seismic, IP/resistivity and geochemical surveys, mapping, prospecting, lake sediment sampling programs and the drilling of more than 390 diamond drill holes. From mid-2000 onwards, the primary focus of exploration has been the 4.7 kilometre long Maverick structural corridor where pods of high grade unconformity-type uranium mineralization have been intersected. The best intercepts to date were obtained from drill holes testing the southwestern portion of this corridor. The potential of intersecting additional mineralization along this corridor is very good and as such it will continue to be a high priority target area. Also of note is that both basement and unconformity-type uranium mineralization have been intersected in a number of underexplored target areas on the property.
In addition to the Maverick Zone, diamond drilling in several other geophysical target areas, has intersected multiple conductors associated with significant structural disruption, strong alteration and anomalous uranium and pathfinder element concentrations. This bodes well for the possibility of discovering additional high grade uranium zones in these areas.
Skyharbour’s former Head Technical Advisor and Director, Rick Kusmirski commented: “I’ve always considered the Moore Uranium Project to be one of the most geologically prospective exploration projects in the Basin, with the potential to host a sizeable high grade uranium deposit. JNR made the initial high grade discovery at the Maverick Zone and after a number of years we sold the project and company to Denison. I am very excited to get back to work on this project with the Skyharbour team. In addition to the Maverick structural corridor, which still has a number of targets that are untested and require follow-up, there are at least nine other target areas throughout the property that contain well defined and extensive conductive systems. The nominal amount of drilling that was carried out in these areas intersected well defined structures associated with multiple graphitic lithologies. Analysis of the drill core returned highly anomalous geochemistry, including uranium mineralization in seven of the target areas.”
2025 Summer and Fall Drilling Plans:
Skyharbour recently completed drilling at the Main Maverick and Maverick East Zones to further expand, characterize and define the extents of the mineralized zones. Both of these high-grade zones are open along strike and at depth, with little historical drilling testing the underlying basement rocks. Furthermore, Skyharbour plans to test regional targets at Moore that have been further refined with modern geophysics and new geological modelling. This drilling took place in conjunction with the multi-phased drilling campaign in 2025 at the adjacent Russell Lake Project. Both drilling programs were run using the Company’s McGowan Lake camp on Highway 914 as a base of operations, making exploration at both properties very cost-effective.
2024 Summer Drill Program:
The phase of drilling on the Moore Project later in 2024 totalled 2,759 metres in nine holes. Of the nine holes, four holes (ML24-10 to -12 and ML24-18) focused on the Main Maverick Zone and five holes (ML24-13 to -17) on the Maverick East Zone. The primary objective of the summer program was to extend and expand the boundaries of the Main Maverick and Maverick East Zones with all but one hole successfully intersecting uranium mineralization. Drill hole ML24-15 which intersected 6.4 m of 1.50% U3O8 successfully expands the Maverick East zone over 40 metres along strike to the northeast with more drilling warranted in the area.
2024 Winter Drill Program:
Drilling on the Moore Project over the winter of 2024 totaled 2,864 metres in nine holes. Seven holes (ML24-01 to -04 and ML24-7 to -09) were drilled at the Main Maverick Zone and two holes were drilled on the Grid 19 target conductors (ML21-05 to -06).
Main Maverick Zone Drilling:
Seven holes totalling 2,221 metres were drilled at the Main Maverick Zone to better define and expand the shallow high-grade mineralized zone. All of these holes were drilled vertically and intersected significant uranium mineralization at the unconformity centred around 265.0 metres to 275.0 metres downhole depth. The majority of the high-grade uranium mineralization at the Main Maverick Zone is sandstone-hosted situated just above the unconformity.
The highlight was hole ML24-08, which intersected 5.0 metres of 4.61% U3O8 between 265.5 metres and 270.5 metres depth including 3.0 metres of 7.30% U3O8 between 266.0 metres to 269.0 metres depth. Another notable hole was ML 24-03, which intersected a broad interval of mineralization grading 1.11% U3O8 over 11.5 metres between 266.8 metres to 278.3 metres depth, including 5.87% U3O8 over 2.0 metres.
Grid Nineteen Drilling:
Two exploratory holes totalling 643.0 metres were drilled at the Grid 19 target area approximately 10km NE of the Maverick Zones, with one hole drilled on the Slice Pond Conductor (ML24-05) and the other hole on the 19 East conductor (ML24-06).
Skyharbour's Spring 2022 Drill Program:
News Release - October 13, 2022
Drilling on the Moore Uranium Project over the spring of 2022 totalled 2,467 metres in seven diamond drill holes. Four exploratory holes (ML22-01 to -04) were drilled at the Grid Nineteen target conductors, two exploratory holes (ML22-05 and -06) were drilled in the Viper target area, and one hole (ML22-07) was drilled at the Maverick East Zone.
Future drill programs will continue to test targets identified by modelling down plunge of the Maverick East Zone, targets along the Grid Nineteen conductors where anomalous geochemistry and geology have been identified, and test other regional targets at the project where the geochemistry/pathfinders and geology are strongly indicative of potentially uraniferous mineralizing systems.
Terms of the Denison-Skyharbour Option Agreement:
Under the terms of the Option Agreement with Denison, Skyharbour acquired a 100% interest in the Moore Project having issued 4,500,000 shares and having made a cash payment of CDN $500,000 as well as funding CDN $3,500,000 in exploration expenditures. Skyharbour owns 100% of the project currently.
