Project Summary:

The South Falcon East Project is a uranium project in the southeast Athabasca Basin and represents a portion of Skyharbour’s larger South Falcon Project. The project covers approximately 12,234 hectares and lies 18 kilometers outside the Athabasca Basin, approximately 55 kilometers east of the Key Lake Mine. Drilling to date on the entire Falcon Point Project area totals over 22,000 metres in more than 110 holes. Over $15 million has been invested in exploration consisting of airborne and ground geophysics, multi-phased diamond drill campaigns, detailed geochemical sampling and surveys, and ground-based prospecting culminating in an extensive geological database for the project area. The project area is in close proximity to two all-weather northern highways and grid power.

Historical exploration at the South Falcon East Project identified an area of U-Th-REE mineralization at the Fraser Lakes Zone B over an area comprising 1.5 km by 0.5 km along an antiformal fold nose cut by an east-west dextral ductile-brittle cross-structure adjacent to a 65 km long EM conductor. The near-surface Fraser Lakes Zone B deposit consists of a current NI 43-101 inferred resource totaling 7.0 million pounds of U₃O₈ at 0.03% and 5.3 million pounds of ThO₂ at 0.023% within 10,354,926 tonnes using a cut-off grade of 0.01% U₃O₈. The independent NI 43-101 technical report by GeoVector Management Inc. supporting this mineral resource estimate was filed on SEDAR on March 20, 2015, by Skyharbour. Independent qualified person, Dr. Allan Armitage, P.Geo., is responsible for the contents of the technical report and comments related to the resource estimate and its parameters.

2024 Phase One Drilling:

The priority will be to confirm and expand the existing mineralization associated with the Fraser Lakes Zone B Uranium Deposit. Infill drilling will confirm the presence and continuity of existing mineralization in preparation for a current updated resource estimate and 3D model in the future. Step out drilling will endeavor to expand the footprint of the deposit, as the current mineralization is open in all directions. Initial focus will be in extending mineralization along strike and down dip into the basement rocks.

Tisdale recently completed the first two drill holes during its phase one drilling program, totalling 442 meters, with phase two set to commence this spring. The results of these two drill holes confirm the presence of mineralized pegmatites and pelitic paragneiss within the deposit and project area. Graphitic pelitic paragneiss are the key lithology associated with uranium deposits within the eastern Athabasca Basin and are a good indication that additional pegmatite deposits as well as basement hosted unconformity-related uranium deposits may be present along the Way Lake Conductor.

Samples of the mineralized intervals within the drill core have been collected and shipped for analysis at the Geoanalytical Laboratory at the Saskatchewan Research Council in Saskatoon, Saskatchewan. Tisdale will provide more detailed results once geochemical analysis of the collected drill core samples is completed, reviewed, and confirmed.

Drill Target Areas at the South Falcon East Uranium Project:

JNR Fraser Lakes Target Area:

Uranium and thorium showings in the JNR Fraser Lakes area (Zone A, Zone B, North and T-Bone) were discovered by ground prospecting of airborne geophysical targets. The mineralized zones are contained within a 65 kilometre long, folded EM conductor system comprised of Wollaston Group graphitic pelitic gneisses and uraniferous granitic pegmatites. Drill testing at Fraser Lakes North intersected low-grade, basement-hosted uranium-thorium mineralization. The drill holes exhibit evidence of major structural reactivation, significant clay alteration, uranium remobilization and basinal brine fluid circulation, all of which are prominent characteristics of the most significant basement-hosted uranium deposits in the Athabasca Basin (e.g. Eagle Point, Millennium, P-Patch and Roughrider). In the T-Bone Lake area, uranium mineralization is accompanied by significant structural disruption and local clay alteration of the host rocks. A major clay-filled fault system intersected in drill holes yielded PIMA infrared spectroscopy results that indicate a preponderance of illite; an important clay mineral that accompanies many of the significant uranium deposits in the Athabasca Basin.

Fraser Lakes Zone B Uranium and Thorium Deposit:

Discovered in 2008, Zone B is located within the broader 6-kilometre by 7-kilometre Fraser Lakes target area where multiple mineralized zones have been discovered along a 65-kilometre-long, folded EM conductor system comprised of Wollaston Group graphitic pelitic gneisses and uraniferous granitic pegmatites. Diamond drilling consisting of 25 holes totaling 4,603 metres has defined a zone of moderately dipping, multiple-stacked uranium and thorium mineralized horizons down to 175 metres that is open to the southwest and east-northeast as well as at depth. Uranium and thorium mineralization is accompanied by highly anomalous concentrations of base metals, rare earth elements and other pathfinder elements. The style of uranium mineralization associated with intrusive rocks is commonly referred to as “Rössing type” mineralization named after the largest, longest-running open pit uranium mine in the world, the Rössing Mine operated by Rio Tinto in Namibia.

JNR Resources Inc., a company acquired by Denison in 2013, announced an initial mineral resource estimate in 2012 (Refiled in March of 2015 by Skyharbour Resources) for the Fraser Lakes Zone B of 6,960,681 pounds U₃O₈ inferred at an average grade of 0.03% U₃O₈ and 5,339,219 pounds ThO₂ inferred at an average grade of 0.023% ThO₂ within 10,354,926 tonnes using a cutoff grade of 0.01% U₃O₈. The independent NI 43-101 technical report supporting this mineral resource estimate was filed on SEDAR on September 26, 2012 by JNR Resources. Independent qualified persons, Dr. Allan Armitage, P.Geo., and Alan Sexton, M.Sc., P.Geo., of GeoVector Management Inc., are responsible for the contents of the technical report and comments related to the resource estimate and its parameters.

The exploration potential of the Fraser Lakes target area is considered exceptional, including the resource expansion potential of the current deposit at Zone B. Geological and geochemical features show distinct similarities to high-grade, basement-hosted deposits in the Athabasca Basin such as Eagle Point, Millennium, P-Patch and Roughrider.

Inferred Mineral Resource Estimate – Fraser Lakes Zone B:

Notes:

1. The effective date of the inferred mineral resource estimate is August 10, 2012.
2. The estimate was prepared by independent qualified person, Dr. Allan Armitage, P.Geo., of GeoVector Management Inc.

Mineral resources that are not mineral reserves do not have demonstrated economic viability.

In July 2015, Skyharbour reported diamond drill assay results from its Falcon Point uranium and thorium property. The drill program consisted of five diamond drill holes totaling 1,278 metres with four of the five holes intersecting uranium and thorium mineralization. Drill hole FP-15-05 intersected a 14.0 metre wide mineralized zone starting at 134.5 metres down-hole depth consisting of the highest grade mineralization found to date in the deposit area. These intersections include 0.172% U₃O₈ and 0.112% ThO₂ over 2.5 metres as well as 0.165% U₃O₈ and 0.112% ThO₂ over 2.0 metres within a broader interval containing 0.103% U₃O₈ and 0.062% ThO₂ over 6.0 metres. This fifth and last hole of the program was lost in the mineralized horizon due to technical issues with the drill rig.

The drill program tested high-priority targets in and around the current uranium and thorium resource at the JNR Fraser Lakes Zone B deposit. It was successful in discovering additional mineralization at higher grades than the deposit average and was the Company's first work program at Falcon Point since acquiring the property from Denison Mines in the summer of 2014.

Potential Future Work Programs:

A focused exploration program is recommended for the South Falcon East property. The primary objective is to define additional resources at the Fraser Lakes Zone B by establishing the potential for extension of the mineralized zone to the east and west of the currently defined deposit. In addition, further interpretation of geochemical and assay data in conjunction with geological and structural analysis will improve the effectiveness of targeting for future drill programs. Skyharbour completed an airborne gravity geophysical survey on the property to cover the entirety of the South Falcon Point Property at a vertical height of 80 m and a line spacing of 200 m for a total of 2,843 line km. The survey has further refined drill targets for future programs.
