Skyharbour Completes Geophysical Program and Mobilizes for Upcoming Drill Program

at its High Grade Moore Uranium Project, Saskatchewan

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

(Frankfurt:SC1P) (the “Company”) is pleased to announce that mobilization has begun for its

2021 diamond drilling program at its flagship 35,705 hectare Moore Uranium Project, located

approximately 15 kilometres east of Denison Mine's Wheeler River project and near regional

infrastructure on the southeast side of the Athabasca Basin, Saskatchewan . The Company has

now completed a 9 km Small Moving Loop EM (SML-EM) geophysical program to refine additional

drill targets and has begun mobilization of drilling equipment for a subsequent minimum 3,500

metre diamond drilling program consisting of at least 7-8 drill holes . This fully funded and

permitted program will focus on following-up on existing unconformity and basement -hosted

targets along the high grade Maverick structural corridor as well as newly defined targets at the

Grid Nineteen area.

Jordan Trimble, President and CEO of Skyharbour Resources, states: “ With the geophysical

results now in hand and final drill targets picked, we are excited to embark on another aggressive

drill program at Moore. We have been very pleased with the results to date at the Maverick East

Zone and believe we have just scratched the surface in our endeavour to delineate high grade

zones of mineralization at depth in the underlying basement rocks. The uranium mineralization

identified during previous drill programs illustrates the strong discovery potential at Moore and

recent geophysical programs and geological modeling have enabled the Company to develop

new regional drill targets in areas such a s Grid Nineteen . Skyharbour is well funded with over

CAD $9 million in cash and stock to continue advancing its flagship Moore Project. The uranium

market has shown notable signs of recovery with increasing equity valuations and improving

sentiment, and this recovery appears to be accelerating.”

Winter/Spring 2021 Geophysical and Diamond Drilling Programs at Moore Project:

Skyharbour recently completed a 9 line-km SML-EM survey at a previously untested area called

Grid Nineteen located between the Rarotonga and East Venice conductors. The focus of this work

2

has been to better define the historic airborne EM conductors in this area and develop drill

targets on these conductor systems.

Skyharbour is planning for an initial 3,500 metre diamond drilling program, consisting of 7-8 holes,

which can be expanded. The drilling will focus on both unconformity and basement-hosted targets

along the Maverick structural corridor and new targets identified in the Grid Nineteen area. The

Company specifically plans to expand the high grade mineralization discovered recently at the

Maverick East Zone, along strike, down-plunge and at depth with a focus on both unconformity-

and basement-hosted mineralization. Other targets along the 4.7 km long Maverick structural

corridor will also be investigated, including the Esker Target, again with a focus on both

unconformity- and basement-hosted mineralization.

Maverick East Target:

The high grade Maverick East Zone has been identified over a minimum of 170 metres strike

length. It is currently a minimum of 10 metres wide, open down dip and is up to 17.9 metres thick

with grades of up to 9.12% U 3O8 (with a minimum grade of 0.1% U3O8). The mineralization is

accompanied by intense clay alteration and geochemical enrichment of pathfinder elements such

as B, Ni and Cu , with the localized high grade uranium mineralization extending from the

unconformity into the basement rocks. The mineralized zone appears to plunge moderately to the

northeast, with minimal drill testing at depth along plunge . In the eastern extent of the Maverick

East Zone, copper values of up to 2.3% Cu along with up to 0.076% U3O8 were obtained from

graphitic, clay-rich fractures within a broader zone of uranium -enriched and clay-altered granitic

pegmatite and granite nearly 100 metres below the unconformity. This may be an important vector

for additional basement-hosted mineralization. Some of the most significant drill hole intersections

in the Maverick East Zone include ML-202, which returned 1.79% U 3O8 over 11.5 metres,

including 4.17% U 3O8 over 4.5 metres and 9.12% U 3O8 over 1.4 metres , as well as recently

announced hole ML20-09, which returned 0.72% U 3O8 over 17.5 metres from 271.5 metres to

289.0 metres, including 1 .00% U3O8 over a 10.0 metre interval in the basement portion of the

interval (279.0 metres to 289.0 metres) . The focus for future drilling in this area will be on the

down-dip, along strike and down-plunge extensions of the Maverick East target.

Maverick Structural Corridor - Northeast Extension and Esker Targets:

Drilling to the northeast of the Main Maverick and Maverick East mineralized zones will take place

along the remaining 2.2 km of the Maverick Structural Corridor that has not been systemically drill

tested. A large portion of this trend has been tested by a series of broadly spaced drill holes and

fences with significant untested gaps . Virtually all the holes exhibited extens ive sandstone and

basement alteration and geochemical enrichment similar to that within the Main Maverick and

Maverick East Zones. As well, narrow intercepts of uranium mineralization have been found in

numerous locations along this portion of the Maverick corridor. Many of these mineralized

intercepts occur at the unconformity, but in a few key areas significant strongly altered basement

structures within prospective graphitic and metasedimentary uni ts are the host for this

mineralization, with only limited drilling of the basement rocks at depth.

The Esker Target lies at the northeastern limits of the Maverick Structural Corridor. Of note from

historical drilling in this area is the anomalous uranium in drill hole MT-04, which returned up to

170 ppm U in the basal 3.0 metres of sandstone and up to 343 ppm U in the top 5.5 metres of the

basement rock. The uranium is accompanied by anomalous amounts of pathfinder elements

including Ni, Co, Cu, Pb, and Zn . Follow-up of the anomalous uranium mineralization has been

limited with the next closest hole MT -10 (also with anomalous U in the sandstone ) located 120

3

metres to the south. Further south in the Esker area, weak uranium mineralization was also

intersected in historical holes ML-165 (1.0 metre of 0.307% U3O8 from 291.85 metres to 292.85

metres), ML-169 (1.5 metres of 0.070% U3O8 at 287.25 metres to 288.75 metres), and ML -171

(0.5 metres of 0.160% U3O8 from 296.2 to 296.7 metres). Drilling will follow-up on the anomalous

uranium encountered in historical holes MT-04 and MT-10 and along trend which has only had

very limited investigation to date.

Grid Nineteen Geophysical Program:

A review of historic al airborne EM identified several conductive features in an area located

between the East Venice and Rarotonga conductor systems that warranted follow-up groundwork.

The airborne conductors lie in a structurally complex area that bridges a break in the east trending

East Venice conductive system and the north trending Rarotonga conductors. A total of 9 line km

of survey was completed utilizing 200 metre loops in a moving array. The program was designed

and has been interpreted by Bingham Geoscience of Saskatoon, and was completed by Patterson

Mining Geophysics of La Ronge. Both Bingham and Patterson have been active in uranium

exploration of the Athabasca Basin for over 35 years and have a wealth of experience in the

district.

The preliminary results from the ground geophysical survey further refined the historical airborne

conductors in the Grid Nineteen area and confirmed the extension of the Raratonga conductive

system to the south. The survey further defined the abrupt change in the strike of the conductive

systems at the southern end of the Grid Nineteen area, from an almost north-south orientation of

the Raratonga conductors to the east -west orientation of the East Venice conductors. Weak

basement-hosted mineralization was intersected in hole ML17-04 (1.0 m of 0.094% U3O8 at 235.0

metres depth) just to the west of this strike change, along with strong structural disruption and

local pathfinder element enrichment in the sandstone of both ML17-04 and follow-up hole ML18-

01. The intersection of these conductive syste ms forms one of several newly developed targets

in the Grid Nineteen area.

Winter 2021 Geophysical Program at Moore:

https://www.skyharbourltd.com/_resources/maps/Moore2021-Geophysics.jpg

The Grid Nineteen area has only seen limited historical drill testing consisting of two holes, one

of which ended in sandstone and failed to test the main conductor target, thus there remains

significant discovery potential in this area. Several drill targets have been developed based on

the preliminary results of the ground geophysical survey, with plans to drill the most accessible

targets during the upcoming drilling program.

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. The project consists

of 12 contiguous claims totaling 35,705 hectares located 42 kilometres northeast of the Key Lake

mill, approximately 15 kilometres east of Denison’s Wheeler River project, and 39 kilometres

south of Cameco’s McArthur River uranium mine. Unconformity style uranium mineralization was

discovered on the Moore Project at the Maverick Zone in May 2000. Historical drill results include

4.03% eU 3O8 over 10 .0 metres including 20% eU 3O8 over 1.4 metres . In 2017, Skyharbour

announced drill results of 6.0% U3O8 over 5.9 metres including 20.8% U3O8 over 1.5 metres at a

vertical depth of 265.0 metres at the Maverick Zone. 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 easily accessible by air and in winter via ice roads which

simplifies logistics and lowers costs.
