NEWS RELEASE

Skyharbour’s Partner Company Basin Uranium Corp. Continues to Intersect Anomalous

Uranium Mineralization at Mann Lake

Vancouver, BC - Skyharbour Resources Ltd.’s (TSX-V: SYH) (OTCQX: SYHBF) (Frankfurt:

SC1P) (the “Company”) partner company, Basin Uranium Corp. (“Basin Uranium”) is pleased to

announce the intersection of significant mineralization from the three-hole Phase 2 drill program

at its Mann Lake project located 25 km southwest of the McArthur River Mine and 15 km to the

northeast along strike of Cameco’s Millennium uran ium deposit. A total of 6,279 metres of

diamond drilling was completed on the Mann Lake property during the 2022 season.

Highlights:

• Drilling continued to intersect notable pathfinder elements (B, Co, Cu, Ni, and Pb) which

provides for vectoring towards uranium mineralization as it is typically associated with

Athabasca Basin unconformity-style mineralization.

• Hole MN22-0007 intersected the unconformity at 671.8 metres and returned anomalous

boron (dravite) and uranium mineralization at and above the unconformity. Dravite is a

boron rich clay mineral, often found in association with uranium mineralization and is

considered an important pathfinder in uranium exploration.

• Notable intercepts include 1,060 ppm B from 669.3 – 669.8 metres (0.5 metres), 931 ppm

B from 668.8 – 669.3 metres (0.5 metres), and 614 ppm boron (B) from 668.8 – 671.8

metres (2.5 metres) in conjunction with 41 ppm U 3O8 from 671.8 – 672.3 metres (0.5

metres).

• Significant polymetallic mineralization was intersected below the unconformity of hole

MN22-007 including 884 ppm Cu from 679.2 – 679.7 metres (0.5 metres) and 158 ppm

Zn from 676.0 – 683.75 metres (17.75 metres).

• Significant boron mineralization was also encountered in hole MN22 -008 which

intersected the unconformity at 649.02 metres and returned 386 ppm B from 646.02 –

648.52 metres (2.5 metres).

Phase Two Drill Program Summary:

The Phase 2 program was comprised of 2,776 metres of diamond drilling over four holes. The

first hole MN22-006 was wedged and re-started at 572 metres (MN22-006A), serving as a follow

up hole to MN22 -002 which was drilled during Phase 1 and hoste d prospective uranium

mineralization. The following two holes MN22 -007 and MN22 -008, targeted the southeastern

portion of the tenure which had previously been untested. This southeastern zone was drilled to

test a strong interpreted basement conductor that was situated on a magnetic low and on the

border of a gravity low anomaly which is interpreted as a basement fault structure.

Hole MN22-006/MN22-006:

This hole was a 150 metre step out to the south -east designed to follow up mineralization

intersected in hole MN22-002 which returned 323 ppm U 3O8 U and 17 ppm Th from 660.05 –

660.55 metres. The hole tested an interpreted basement conductor (2022 Mobile MT resistivity

survey), inverted resistivity low, corresponding with a northeast ground UTEM conductor (A3),

magnetic low (interpreted metasediment basement) and was along the edge of a gravity low.

Hole MN22-006A was successful at crossing the unconformity at 617.48 metres and intersecting

the intermittent psammite, pegmatite, and monzodiorite units that make up the basement

lithologies but no notable assay results were returned.

Hole MN22-007:

This hole was designed to test an interpreted basement conductor, inverted resistivity low (2022

Mobile MT resistivity survey), corresponding with a northeast ground UTEM conductor (A3),

magnetic low (interpreted metasediment basement) and is along the edge of a gravity low.

Hole MN22-007 intersected graphite enriched psammite throughout the entirety of the basement

rocks until about 880 metres, whereby it became more silicified until the end of the hole at 887

metres. Two major fault structures with abundant graphite mineralization were intercepted in the

basement, potentially serving as an explanation to the resistivity low and magnetic lows. Possible

origins of the graphite mineralization could be from the graphite bearing pelites, however, due to

the abundant graphite mineralization in conjunction with the major fault zones in the basement, it

is possible that the graphite is being supplied from the basement structures.

Further investigation along the m argins of this magnetic low and gravity low anomaly of MN22 -

007 is required in order to further understand the source of the graphite mineralization and

potential interception of uranium mineralization in this area.

Hole MN22-008:

This hole was designed to test an interpreted basement conductor, inverted resistivity low (2022

Mobile MT resistivity survey), corresponding with a northeast ground UTEM conductor (A3),

magnetic low (interpreted metasediment basement) and is along the edge of a gravity low.

The most significant intersection in the upper portion of MN22-008 was the dravite mineralization

present in the fault zones and fractures in the upper Athabasca group sediments. These were

more well developed than previous drill holes and the potential fo r nearby structures with

3

remobilized mineralization in the area is still high. In the basement, the intersected graphitic

metasediments host to significant amounts of pyrite and minor chalcopyrite. The presence of a

fault zone in proximity to the unconform ity is notable, the graphite could be diagenetic and or

could be present due to remobilization within basement structures. The chalcopyrite

mineralization has the potential to host gold mineralization and further follow -up in the area is

recommended. The g raphite mineralization in conjunction with the pyrite does explain the

presence of a resistivity low at depth.

About Mann Lake:

Skyharbour entered into an Option Agreement (the “Agreement”) with Basin Uranium whereby

Basin Uranium has an earn-in option to acquire a 75% interest in the Mann Lake Uranium Project.

Under the Option Agreement, Basin Uranium Corp will contribute cash and exploration

expenditure consideration totalling CAD $4,850,000 over a three -year period (“Project

Consideration”). Of the Project Consideration, $850,000 will be in cash payments to Skyharbour

and $4,000,000 will be in exploration expenditures on the project. Basin Uranium Corp will also

issue to Skyharbour the equivalent value of CAD $1,750,000 in shares of Basin Uranium over the

three-year earn-in period to complete the earn-in.

The Mann Lake Uranium Project is strategically located 25 km southwest of the McArthur River

Mine, the largest high-grade uranium deposit in the world, and 15 km to the northeast of Cameco's

Millennium uranium deposit. The Mann Lake project is also adjacent to the Mann Lake Joint

Venture operated by Cameco (52.5%) with partners Denison Mines (30%) and Orano (17.5%).

Denison Mines acquired International Enexco and its 30% interest in the project after a 2014

winter drill program discovered high -grade, basement -hosted uranium mineralization at this

adjacent project.

QA/QC:

Samples were sent for geochemical analysis with SRC Geoanalytical Laboratories, Saskatoon

for the following analyses: ICP-MS1 (Sandstone) and ICP-MS2 (Basement) which includes both

partial and total digestion methods as well as an additional Boron analysis. Over limit analysis

were completed using U3O8 total digestion when U >1,000ppm.

On receipt of final certificates of analysis, the QA/QC sample results were reviewed to ensure the

order of samples were reported correctly, that the blanks ran clean, and that the results for each

standard had minimal variance from its certified value. QA/QC for the Mann Lake drilling included

certified reference material (“CRM’s”) and blanks that were inserted into each sample batch in

order to verify the analytical from the lab.

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 eighteen

projects, ten of which are drill -ready, covering over 460,000 hectares 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

4

returned drill results of up to 6.0% U3O8 over 5.9 metres including 20.8% U3O8 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 drill

intercepts over a large property area with robu st exploration upside potential. The Company is

actively advancing these projects through exploration and drill programs.

Skyharbour has a joint -venture with industry -leader Orano Canada Inc. at the Preston Project

whereby Orano has earned a 51% interest in the project through exploration expenditures and

cash payments. Skyharbour now owns a 24.5% interest in the Project. Sky harbour also has a

joint venture with Azincourt Energy at the East Preston Project whereby Azincourt has earned a

70% interest in the project through exploration expenditures, cash payments and share issuance.

Preston and East Preston are large, geological ly prospective properties proximal to Fission

Uranium's Triple R deposit as well as NexGen Energy's Arrow deposit.

Skyharbour has several active option partners including: ASX-listed Valor Resources on the Hook

Lake Uranium Project, CSE-listed Basin Uranium Corp. on the Mann Lake Uranium Project, and

CSE-listed Medaro Mining Corp. on the Yurchison Project. More recently, Skyharbour announced

two new earn -in option agreements with Yellow Rocks Energy, a private Australian entity, to

option the Wallee and Usam Island projects, and Tisdale Clean Energy at the South Falcon East

Project.

Furthermore, the Company owns a 100% interest in the South Falcon Point Uranium Project on

the eastern perimeter of the Basin. Skyharbour has recently optioned the South Falco n East

Project, a uranium project in the southeast Athabasca Basin and represents a portion of the larger

South Falcon Project, to Tisdale Clean Energy whereby Tisdale will fund exploration, pay

Skyharbour in cash, and issue shares of the company over a five-year earn-in period.

Collectively, Skyharbour has now signed option agreements with partners that total over $34

million in partner-funded exploration expenditures, over $22 million in stock being issued and just

under $15 million in cash payments comi ng into Skyharbour, assuming that these partner

companies earn-in the full amounts at their 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.
