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

Exploration Programs

MAY 16, 2024 TSX-V:NSU

NORTH SHORE URANIUM REPORTS DRILL PROGRAM RESULTS:

URANIUM MINERALIZATION CONFIRMED AT TWO TARGETS

North Shore Uranium Ltd. (TSX-V: 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 U 3O8 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, t hree 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 ba sed 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 t he 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 project ed 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 reach ed, the Company will consider re -testing th is 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.”

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 195.0 m.

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 condu ctor 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) w ere 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.
