NEWS RELEASE

Skyharbour’s Partner Company Basin Uranium Corp. Announces Completion of Phase

One Drilling at Mann Lake Uranium Project

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

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

announce it has completed its phase one 2022 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 uranium deposit. The phase one program consisted of five holes totalling 3,503 metres

with the unconformity being intersected between 608 metres to 651 metres in all holes. This was

the first significant drill program undertaken on the property since 2007.

The second phase of drilling is planned for the fall of this year and will consist of approximately

3,500 metres. Results from both the phase one drill program and upcoming geophysical surveys

at Mann Lake will be used for targeting and follow -up in the second phase. The geophysical

program, consisting of gravity and airborne mobile magnetotellurics (mobile MT) surveying, is

anticipated to commence in early June.

Phase One Highlights:

• 3,503 metres of diamond drilling completed in five vertical holes

• Holes MN22002, MN22003 and MN22004 all intersected uranium dominant, anomalous

radioactive intervals in the basement rocks

• Core samples from all holes have been submitted to the Saskatchewan Research Council

(SRC) Geoanalytical laboratories in Saskatoon, Saskatchewan

• Geophysical surveying (mobile MT and gravity) to begin in June

"Our phase one drill program successfully intersected uranium mineralization over one kilometre

south of any previous historic al drilling at Mann Lake. Our drilling was focused on testing the

unconformity along significant conductors as neighbo uring deposits in the area all occur along

such conductors.” commented Basin Uranium’s CEO, Mike Blady. “Assay results from phase one

drilling, all of which remain pending, in conjunction with the upcoming geophysical program will

2

be used to define drill targets for our second phase this fall.”

Mann Lake Drill Plan:

Drill Hole MN22002:

Hole MN22002 w as designed to test the same conductor and geophysical setting as hole

MN22001, collared 400 metres to the N -NE. It was successful crossing the unconformity and

entering basement metasediments (mostly psammite) as well as locating anomalous radioactive

values with the handheld scintillometer and downhole probe. Monazite and allanite mineralization

at th e anomaly was also observed. Graphite mineralization was also noted in basement

psammites along foliations and within some fractures.

Drill Hole MN22003:

Hole MN22003 was a step-out of 350 metres to the N-NE of hole MN22002 and was designed to

test the same conductor and geophysical setting. Blood -red hematite paleoweathering at the

unconformity and silica mottling have overprinted the texture of the psammite directly below the

unconformity. Dravite-clay alteration can be found within fractures throughout the paleoweathered

section and decreasing in prevalence with depth.

This hole was successful in crossing the unconformity and intersecting radioactively anomalous

intervals with allanite mineralization. Intervals wi thin the basement rocks were found to contain

graphite and dravite mineralization.

Drill Hole MN22004:

Hole MN22004 w as a 150 met re step-out along the conductor and strike of hole MN06-003A

which intersected 12 metres of hematized paleoweathering up hole of the unconformity which

returned elevated gamma probe readings. An interpreted basement conductor, mag low and

gravity low were present. While the hole did not intersect any lithology resembling the target

Wollaston Group metasediments , t he intersection of minor monazite mineralization in close

proximity to strong clay alteration remains a potentially interesting indication of uranium

mineralization nearby.

Drill Hole MN22005:

This hole was designed to test the intersection of a NE-trending structure parallel to hole MN06-

005 which returned over 1,000 ppm boron and elevated radioactivity at the unconformity, as well

as a cross cutting E-W trending structure on strike to hole MN06-002 where elevated radioactivity

and hematite paleoweathering occur at the unconformity.

The hole was successful in intersecting a strongly hematite altered basement fault structure up

hole and in close proximity to the unconformity. There was also a small interval of granitized

strongly foliated metapelite intersected just below the unconformity, followed by granitic gneiss

with intercalated pegmatites to the end of hole. Within the granite basement, clay dravite

mineralization occurred, coating the surfaces of several low angle fractur es between 652 m -

663m.

About Mann Lake:

Skyharbour has 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

3

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.

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 fifteen

projects, ten of which are drill -ready, covering over 450,000 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

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.

Skyharbour now owns a 15% interest in the Project. Preston and East Preston are large,

geologically prospective properties proximal to Fission Uranium's Triple R deposit as well as

NexGen Energy's Arrow deposit. Furthermore, the Company owns a 100% interest in the South

Falcon Point Uranium Project on the eastern perimeter of the Basin, which contains a NI 43-101

inferred resource totaling 7.0 million pounds of U 3O8 at 0.03% and 5.3 million pounds of ThO 2 at

0.023%.

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