News Release

Skyharbour Commences Summer Diamond Drilling Program at its Moore Uranium Project,

Saskatchewan

Vancouver, BC - Skyharbour Resources Ltd. (TSX-V:SYH) (OTCQX:SYHBF) (Frankfurt:SC1P)

(the “Company”) is pleased to announce that the Company has commenced a 2,500 metre summer

drill program at its 100% owned, 35,705 hectare high-grade Moore Uranium Project. The project is

located approximately 15 kilometres east of Denison Mine’s Wheeler River project and proximal to

regional infrastructure for Cameco’s Key Lake and McArthur River operations in the Athabasca

Basin, Saskatchewan. The drill program has been designed to expand and further characterize the

high-grade Main Maverick and Maverick East Zones, utilizing the existing Moore Lake camp , with

Skyharbour’s McGowan Lake camp at the Russell Lake Project serving as a secondary base of

operations. The Company is fully funded and permitted for this drill program, as well as for future

drilling, including 4,000 – 5,000 metres to be drilled later in the fall of 2024 at the adjacent Russell

Lake project.

Highlights:

• Skyharbour’s summer drill program consisting of 2,500 metres in seven to nine holes has

commenced at the Moore Project

• The Company is fully funded and permitted for this drill program and for an additional 4,000-

5,000 metres of follow-up drilling at the company’s adjacent Russell Lake project later this

fall

• Local i nfrastructure including the McArthur River Mine haul road, powerlines and the

McGowan Lake camp at Russell will help to materially lower all-in drill costs

• The drilling at Moore will be focused on the Main Maverick and Maverick East Zones to further

expand, characterize and define the extents of the mineralized zones

• These high-grade zones of uranium mineralization are relatively shallow , between 250-280

metres from surface

• There remains expansion potential at both of the high-grade Main Maverick and Maverick

East Zones; furthermore, substantial portions of the 4.7 kilometre long Maverick corridor

remain to be systematically drill-tested leaving robust discovery potential along strike as

well as at depth in the basement rocks

Jordan Trimble, President and CEO of Skyharbour, stated: “We are excited to commence drilling

again with plans to carry out an initial program at Moore followed by a larger program at Russell

totalling 7,000-8,000 metres combined across both projects. We have continued to expand the high-

grade zones on the Moore Project and will be drilling in this program to further delineate the

numerous zones of uranium on the Maverick Corridor taking advantage of regional infrastructure to

bring our costs down. Furthermore, with the recent discovery of high-grade uranium mineralization

at Russell in the newly identified Fork Zone, this has been a very successful year of drilling thus far

for Skyharbour with much more news to come at both Moore and Russell as well as at the various

partner-funded projects.”

Summer Diamond Drilling Program at Moore:

Skyharbour has initiated another phase of drilling, consisting of 2,500 metres in seven to nine drill

holes, at its high-grade Moore Project in the Athabasca Basin. The Company is planning to focus on

the Main Maverick and Maverick East Zones to further expand, characterize and define the extents

of the high-grade uranium mineralization. Both of these high-grade zones are potentially open along

strike and at depth, with the basement rock having significantly less historical drill testing. Numerous

additional regional targets exist elsewhere on the property, including targets along the full extent of

the Maverick Corridor, which may be tested during this or future drilling programs on the property.

Drilling at the Maverick Corridor is planned within the Main Maverick and East Maverick Zones to

further delineate and expand the currently identified mineralized zones. Recently completed

modelling of the mineralized zones has identified areas with potential to host additional high-grade

uranium mineralization, including between the two delineated zones, which will be tested as part of

the summer drill program.

The Main Maverick Zone is characterised by high-grade basement- and unconformity -hosted

uranium mineralization, with a best interval drilled previously by Skyharbour of 6.0% U3O8 over 5.9

metres at 265.0 metres depth, including 20.8% U 3O8 over 1.5 metres, in hole ML-199. A highlight

from the winter drill program completed earlier this year was from hole ML24-08 which intersected

5.0 metres of 4.61% U3O8 from a relatively shallow downhole depth of 265.5 metres to 270.5 metres,

including 10.19% U3O8 over 1.0 metres, at the Main Maverick Zone.

areas.jpg

At the Maverick East Zone , Skyharbour previously drilled a high-grade uranium intercept of 1.79%

U3O8 over 11.5 metres at 270.0 metres depth, including 4.17% U 3O8 over 4.5 metres and 9.12%

U3O8 over 1.4 metres in hole ML-202.

Moore Uranium Project Overview:

In June 2016, Skyharbour secured an option to acquire Denison Mine's Moore Uranium Project, on

the southeastern side of the Athabasca Basin, in northern Saskatchewan and has fulfilled its earn

in. The project consists of 12 contiguous claims totaling 35,70 5 hectares located 42 kilometres

northeast of the Key Lake mill, approx. 15 kilometres east of Denison’s Wheeler River project, and

39 kilometres south of Cameco’s McArthur River uranium mine. Unconformity -type uranium

mineralization was discovered on the Moore Project at the Maverick Zone in April 2001. Historical

drill highlights include 4.03% eU3O8 over 10 metres, including 20% eU3O8 over 1.4 metres, in ML-61.

In 2017, Skyharbour announced drill results of 6.0% U 3O8 over 5.9 metres, including 20.8%

U3O8 over 1.5 metres at a vertical depth of 265 metres, in hole ML -199. In addition to the Maverick

Zone, the project hosts other mineralized targets with strong discovery potential which the Company

plans to test with future drill programs. The project is fully accessible via winter and ice roads which

simplifies logistics and lowers costs. Large proportions of the property are accessible in the summer

as well.

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 twenty-

nine projects, ten of which are drill-ready, covering over 580,000 hectares (over 1.4 million acres) of

land. Skyharbour has acquired from Denison Mines, a large strategic shareholder of the Company,

a 100% interest in the Moore Uranium Project whic h 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 ret urned drill results of up to 6.0% U 3O8 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 several

high-grade uranium drill intercepts over a large property area with robust exploration upside potential.

The Company is actively advancing these projects through exploration and drill programs.

Skyharbour has joint -ventures with industry -leader Orano Canada Inc., Azincourt Energy and

Thunderbird Resources (previously Valor) at the Preston, East Preston and Hook Lake Projects,

respectively. The Company also has several active earn -in option partne rs including: CSE -listed

Basin Uranium Corp. at the Mann Lake Uranium Project; CSE -listed Medaro Mining Corp. at the

Yurchison Project; North Shore Uranium at the Falcon Project; and TSX -V listed Tisdale Clean

Energy at the South Falcon East Project which is host to the Fraser Lakes Zone B Uranium and

Thorium Deposit. In aggregate, Skyharbour has now signed earn-in option agreements with partners

that total to over $33 million in partner -funded exploration expenditures, over $27 million worth of

shares being issued and over $20 million in cash payments coming into Skyharbour, assuming that

these partner companies complete their entire earn-ins at the 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.
