North Shore Uranium Reports Drill Program Results: Uranium Mineralization Confirmed at Two Targets

VANCOUVER, BC / ACCESSWIRE / May 16, 2024 / North Shore Uranium Ltd. (TSXV:NSU) ("North Shore" or the "Company") is pleased to announce that multiple samples collected from two of the first three uranium prospects drilled by the Company at its 55,699-hectare Falcon Property ("Falcon" or the "Property") at the eastern margin of the Athabasca Basin in Saskatchewan have returned anomalous uranium values of greater than 300 ppm U₃O₈ and up to a maximum of 572 ppm U₃O₈ (Table 1). The Company is now planning for future exploration programs on the Property.

As reported on March 20, 2024, three targets were drilled along a strong, dominantly northeast-trending electromagnetic ("EM") conductor system, P03, P08 and P12 (Figure 1). These results confirmed the encouraging field findings for P03 and P08 that were based on downhole gamma probe readings and geologic observations. Uranium mineralization was confirmed at P03 and P08 with the most significant intersection being at P08, 316 ppm U₃O₈ over a 4.7 metre interval with a peak value of 572 ppm U₃O₈. The following summarizes the Company's drilling results and future plans:

• P03. A blocky fracture zone and interpreted brittle fault with graphite-rich gouge was encountered between 193.5-196.0m coincident with the projected location of the modelled EM conductor. Below this fault zone from 196.6 to 209.0m, multiple samples had elevated uranium content including two samples with greater than 300 ppm U₃O₈.
• P08. A 4.7m interval between 42.3-47.0m returned 316 ppm U₃O₈ with one sample in the interval returning the highest reading from the program, 572 ppm between 42.3-42.8-m. From 102.3-105.5m, a brittle pegmatitic and graphitic fault zone was intersected at the projected depth of the EM conductor.
• Next Steps. Given these encouraging results, the Company will evaluate potential options for further evaluation of the uranium-bearing structures associated with targets P03 and P08, including drilling deeper and/or shallower and/or along strike of the interpreted EM conductor. As the modelled target at P12 was not reached, the Company will consider re-testing this target. In addition, multiple high-priority target zones that have been identified at Falcon have not yet been evaluated by drilling. The Company is currently planning a field program to investigate the highest priority targets by mapping and prospecting and continues to prioritize targets for field evaluation and future drilling.

Mr. Brooke Clements, President and CEO of North Shore stated: "We are very encouraged to have confirmed near-surface uranium mineralization at two of the first three targets drilled at Falcon during our maiden drill program. These results affirm our belief that Falcon has great uranium exploration potential, emphasizing the importance of following up on these results as well as testing other compelling untested EM conductor zones that we have identified. We believe that we have just scratched the surface at Falcon and we look forward to future exploration programs on the Property."

TABLE 1: FALCON PROPERTY DRILLING RESULTS

¹ICP-MS uranium total digestion analysis results were converted to U₃O₈ ppm values. The cutoff and anomalous U₃O₈ value is defined as 100 ppm for this news release. Minimum sample interval, 0.5 m. NAR= no anomalous results. All reported sample depths are drill hole depths and intervals and do not reflect true thicknesses.

²The drillhole was abandoned at 106m owing to unstable ground conditions prior to reaching the target depth of 125m.

Target P03
An interpreted section from drillhole FN24001, which was drilled to a depth of 230m at target P03 is shown in Figure 2.

Underneath six metres of overburden, an alternating succession of metasedimentary rocks comprised of variably garnet-rich graphitic pelitic gneisses crosscut by numerous pegmatites was encountered to 222.5m. A blocky fracture zone and interpreted brittle fault with graphite-rich gouge was encountered within the graphitic gneiss unit between 193.5-196.0m; the projected EM conductor intersection depth was 195.0m. The key interval is just below this fault zone from 196.6-209.0m where multiple samples had elevated uranium content including three samples with greater than 300 ppm U₃O₈ with the highest value being 378 ppm U₃O₈ (Table 1). Strong localized chlorite and silica alteration and multiple pegmatite intrusions were observed in this zone. Anomalous nickel values between 275 and 527 ppm were reported between 193.0- 197.1m. Anomalous molybdenum values between 140 and 193 ppm were reported in three samples between 200.6-203.1m. The combination of the spatial relationship between anomalous uranium content, the graphitic horizon, the structure and alteration are exploration criteria that are important when exploring for a basement-hosted uranium deposit. The Company will consider further investigation of this structure at depth and/or along the strike of the associated EM conductor system.

Target P08
An interpreted section from drillhole FN24002, which was drilled to a depth of 144m at target P08 is shown in Figure 3.

After intersecting 30.5 metres of overburden, an alternating succession of metasedimentary rocks comprised of variably garnetiferous and graphitic pelitic gneiss and schist cross-cut by numerous plagioclase and K-feldspar granitic pegmatites was encountered to 132.3m. Granitic gneiss intersected by K-feldspar granitic pegmatites is present until the end of hole at 144m. The graphitic units were host to up to 30 percent graphite, with localized patches up to 60 percent. Two zones with elevated uranium were encountered. Within a zone from 40.6-49.0 m, a 4.7m interval between 42.3-47.0m returned 316 ppm U₃O₈ with the highest reading in the interval being 572 ppm between 42.3-42.8m. This interval is associated with an interpreted brittle fault zone between 43.9-49.0m. Between 67.6-71.0 m, a pegmatite-rich brittle fault zone comprised of fractured pegmatites and blocky and rubbly graphitic metasediments was encountered. A 3.4m interval between 67.6-71.0m had uranium values in samples ranging from 110-128 ppm U₃O₈. The entire graphitic schist upper portion of the hole displayed very strong patchy chlorite-cordierite-hematite-illite alteration to 102.3m. From 102.3-105.6m, a brittle pegmatitic and graphitic fault zone was intersected at the projected depth of the EM conductor along with strong bleaching (illite+/-sericite) clay alteration, strong hematite and chlorite along fractures and patchy silica alteration. The alteration minerals associated with the interpreted structure can be indicative of a proximal hydrothermal system and significant uranium was encountered associated with pegmatites in the upper brittle fault zone. The Company will consider further investigation of these interesting features in the future.

Laboratory Analyses, Quality Control, Quality Assurance and Analytical Procedures
The analyses were performed by the Saskatchewan Research Council Geoanalytical Laboratories in Saskatoon, Saskatchewan ("the SRC") and 205 samples from the three holes were analyzed. All samples were prepared by crush & grind (PREP-01) then analyzed by ICP-MS total and partial digestion (ICP-MS2: Basement), Boron by fusion/ICP-OES and Gold by Lead fusion Fire Assay (Au1). Select radioactive samples (>600CPS, RS125 SRC scintillometer) were analyzed with the ICP1 partial and total digestion method instead of the ICP-MS2 method due to high radioactivity.

The drill program was managed by TerraLogic Exploration Inc, ("TerraLogic") including the selection of samples for analysis in the field and shipment of the samples to the SRC. TerraLogic adheres to best management exploration practices, including Quality Assurance and Quality Control (QA/QC). All standard operating procedures have been developed and overseen by Jarrod Brown M.Sc., P.Geo. of TerraLogic, a Qualified Person as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects.

QA/QC protocols were maintained through the random insertion of blanks and certified reference material (standards) throughout the drill core sampling process. The drill core was split in half with a manual splitter in the field, select split sample intervals were then placed in a sealed bag and transported by TerraLogic personnel to the SRC; the remainder of the core was stored on site. Upon receipt of the results from the SRC, the program, TerraLogic compiled and assessed all of the analytical data including the QAQC standard and blank data collected during the 2024 season. All standards returned acceptable values based on the following protocol: Failure Limit = Accepted CRM value +/- 3x standard deviations.

Falcon Property Background Information
Falcon is a highly prospective uranium exploration project with a limited exploration history at the eastern margin of the Athabasca Basin in an area of Saskatchewan that is seeing increased exploration activity and recent discoveries. Reinterpretation of EM data complemented by geophysical data acquired in 2022 has allowed the Company to identify high priority uranium targets in areas with limited previous drilling. The Property is located approximately 35 kilometres east of the active Key Lake uranium mill and former mine. The new uranium discovery potential at Falcon is significant including shallow basement-hosted unconformity-style mineralization and pegmatite-hosted mineralization similar to that discovered at the Fraser Lakes Zone B uranium resource located just three kilometres south of the Property.

Falcon consists of 15 mineral claims; four of the claims comprising 12,791 hectares are 100 percent-owned by the Company and the remaining 11 claims totaling 42,908 hectares are subject to an option agreement with Skyharbour Resources Ltd. Under the terms of the option agreement, North Shore can earn an 80% interest in the 11 claims and has the option to purchase the remaining 20% interest after it has earned its initial 80% interest.

About North Shore Uranium
The near-term business objectives of North Shore Uranium are to become a major force in exploration for economic uranium deposits at the eastern margin of Saskatchewan's Athabasca Basin, a tier-one jurisdiction for discovering new mineable high-grade uranium deposits. The Company will work to achieve those objectives by conducting exploration programs on its two properties, Falcon and the West Bear Property, which is located 90 kilometres northeast of Falcon, and by evaluating opportunities to increase its portfolio of properties in the region.
