Skyharbour Doubles Extent of Maverick East Zone with Additional High Grade Uranium

Drill Results and Announces Upcoming Fully-Funded Summer 2020 Drill Program

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

SC1P) (the “Company”) is pleased to announce the results from its 2020 winter/spring diamond

drilling program at its 100% owned, 35,705 hectare Moore Uranium Project, approximately 15

kilometres east of Denison Mine’s Wheeler River project and proximal to regional infrastructure

for Cameco’s Key Lake/McArthur River operations in the Athabasca Basin, Saskatchewan. Drill

hole ML20-04 doubled the known strike extent of the Maverick East Zone by intersecting a

discrete basement-hosted zone of uranium mineralization from 273.9 metres to 2 78.4 metres

downhole. The interval returned 4.5 metres of 0.38% U3O8 with a basal high grade basement

intercept returning 0.5 metres of 1.43% U3O8. Additional drilling in the Maverick East confirmed

the continuity and structural control of the zone both internally and peripherally. A greater

understanding of the Maverick Structural Corridor was also obtained by additional drilling in the

Viper and Maverick NE target areas.

Highlights:

• Hole ML20-04 was drilled 50 metres east of the currently defined Maverick East Zone

and returned 0.38% U3O8 over 4.5 metres from 273.9 metres to 278.4 metres downhole

including 1.43% U3O8 over 0.5 metres.

• This mineralized intercept in ML20-04 is a discrete zone of mineralization hosted in clay

altered granitic assemblages within the basement and extends the known extent of the

Maverick East Zone by over 50 metres, doubling its known strike length. The intervening

50 metres has only marginally been drill tested.

• Hole ML20-05 was drilled within the central portion of the known Maverick East Zone

and returned two zones of mineralization: 0.23% U3O8 over 9.5 metres at 272.5 metres

to 282.0 metres straddling the unconformity and 0.13% U3O8 over 2.5 metres below the

unconformity at 287.5 metres to 290 metres downhole.

• Hole ML20-06 was drilled within the central portion of the newly extended Maverick East

Zone. The hole grazed the down dip extent of the steeply dipping Maverick fault system,

intersecting four zones of mineralization over a 30 metre downhole interval of sandstone

and basement rocks. Two sandstone-hosted mineralized intervals grading 0.12% U3O8

2

and 0.22 U3O8 were intersected at 269.1 metres to 270.2 metres and 274.2 metres to

276.3 metres downhole respectively, and two narrow 0.5 metre thick basement intervals

grading 0.22% U3O8 and 0.13% U3O8 were intersected at 288 metres and 297.5 metres.

• A deeper exploratory hole (ML20-02) tested the down dip extent of the Viper target area

located 1.5 kilometres NE of the Main Maverick Zone; at 250 metres below the

unconformity, the drilling confirmed the presence of multiple zones of structurally

disrupted and altered pelitic and graphitic meta-sedimentary units 100 metres below

previous intercepts accompanied by anomalous values of B, V, Ni and Cu throughout

the basement rock lithologies.

• Substantial portions of the 4 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.

• Planning is currently underway for a 2,500 metre summer diamond drilling program to

commence later in the summer. The program is fully funded and permitted.

Jordan Trimble, President and CEO of Skyharbour Resources, stated: “We are very pleased with

the results from this most recent drill program at our flagship Moore Project as we continue to

discover new high grade uranium mineralization in the underlying basement rock at the Maverick

corridor and significantly expanded the Maverick East Zone. We will be commencing a summer

drill program to follow up on these results and test more extensively highly prospective potential

feeder zones in the basement rock at the Maverick corridor. Skyharbour is well positioned to

benefit from the continuing uranium market recovery with strong discovery potential and ample

upcoming news flow from its drilling at Moore, as well as from its partner co mpanies’ Orano

Canada Inc. and Azincourt Energy’s continued exploration programs at the Preston and East

Preston Projects.”

Richard Kusmirski, Head Geologist of Skyharbour Resources, stated: “ We are successfully

increasing the size of high grade uranium zones at the Maverick corridor and look forward to

exploring for additional uranium deposits on the project lands. Much of this uranium mineralization

is associated with basement lithologies a characteristic common to recent discoveries like

NexGen’s Arrow Deposit, Fission’s Triple R Deposit and Denison’s Gryphon Deposit. We are

excited to commence our upcoming fully -funded summer drilling program with details on the

program forthcoming.”

Winter/Spring 2020 Drill Program Summary:

The recently completed winter /spring diamond drilling program totaled 2,328 metres in six drill

holes. These holes tested the Maverick NE target area (holes ML20-01 and ML20-03), the Viper

target area (hole ML20-02), and the Maverick East target area (holes ML20-04, ML20-05 and

ML20-06).

Drill hole ML20-04 was drilled 50 metres northeast of the Maverick East Zone following up on a

historical drill hole where elevated uranium values were identified in the basement rocks. This

new hole returned 0.38% U 3O8 over 4.5 metres from 273.9 metres to 278.4 metres downhole,

including 1.43% U 3O8 over 0.5 metres. The mineralization is located just at and below the

unconformity at 274.5 metres downhole. It is hosted by a variably hematized and brecciated

granitic hydraulic breccia with clasts of overlying sandstone incorporated into the granite as well

as hematized, faulted clay altered Archean granite. The hole successfully extended the extent of

the Maverick East Zone by over 50 metres, leaving substantial potential open for the intervening

50 metres.

Drill hole ML20-05 was drilled in the central portion of the Maverick East Zone and intersected a

relatively broad 9.5 metre interval of 0.23% U3O8 starting at 272.5 metres downhole, as well as

3

2.5 metres of 0.1 3% U 3O8 over 2.5 metres starting at 287.5 metres depth. The upper

mineralized intercept straddles the unconformity at 277.2 metres and is hosted within clay altered

to clay replaced desilicified sandstone and clay altered to replaced Archean granite, while the

second intercept is hosted entirely in altered Archean granite. The mineralization is found both as

disseminations and as interstitial blebs in the sandstone and as fracture fillings in the basement

rocks. The combination of lithologic and structural control confirms the continuity of mineralization

in the central portion of the previously identified zone.

Corridor.jpg

Drill hole ML20-06 was collared in the central undrilled portion of the newly extended Maverick

East Zone. It intersected four zones of discrete intervals of uranium mineralization over a broad

30 metre interval of sandstone and basement lithologies. The results included : 1.1 metres of

0.12% U3O8 (269.1 to 270.2 metres downhole); 2.1 metres of 0.22% U3O8 (274.2 metres to 276.3

metres downhole); 0.5 metres of 0.22% U3O8 (288.0 metres to 288.5 metres downhole); and 0.5

metres of 0.13% U3O8 (297.5 metres to 298.0 metres downhole). Mineralization occurs as weak

to moderately localized features with in a broad package of sandstone, clay altered to replaced

pelitic and graphitic basement rocks. The broader intervals occur within zones of intense

desilicification and core loss in the sandstone. The unconformity is estimated to be at 274 metres

depth. The overall geometry of the mineralization suggests that the hole was drilled several

metres south of its optimal target leaving open the possibility of delineating more extensiv e

mineralization in this part of the Maverick East Zone.

In the Maverick NE portion of the Maverick Structural Corridor, holes ML20-01 and ML20-03

intersected geochemically anomalous values of U, B, Ni, Co, Pb, Zn in the sandstone and

basement rocks as well as prospective meta -sedimentary and graphitic lithologies cut by

geochemically fertile structures. The area is notably complex, as there is a significant break in the

structural and conductive elements found in the area. The area remains prospective a s areas of

structural complexity have great potential for hosting significant mineralized zones.

A deep exploratory hole (ML20-02) testing the down dip extent of the Viper target located 1.5

kilometres NE of the Main Maverick Zone. At approximately 250 metres below the unconformity,

the drilling confirmed the presence of structurally disrupted and altered pelitic and graphitic meta-

sedimentary units 100 metres below previous intercepts , accompanied by anomalous values of

B, V, Ni and Cu throughout the basement lithologies. This is the deepest test of the Viper area to

date, and confirms the geological and geochemical continuity of the Maverick Structural corridor.

Upcoming Summer 2020 Drill Program Plans:

Skyharbour is funded and permitted for a 2,500 metre 2020 summer diamond drilling program

slated to commence later this summer . This drill program will test both unconformity and

basement hosted targets along the high grade Maverick corridor, as well as essentially untested

prospective conductive corridors identified by Skyharbour’s technical team. Of particular interest

are potential underlying basement feeder zones to the unconformity -hosted high-grade uranium

present at the Maverick corridor. These targets have seen limited historical drill testing.

Uranium Market Commentary and Update:

The uranium market has recently shown notable signs of recovery with increasing uranium prices

and improving sentiment, and this recovery appears to be accelerating amid recent news and

several sector developments. Analysts that cover the sector have state d that this could be a

sustained upswing as they are currently seeing some of the best fundamentals since pre -

4

Fukushima which should be supportive of higher uranium prices as a major supply-side response

is playing out while the sticky demand -side continues to improve. Uranium production is on the

decline and was expected to be approx. 140 million lbs U3O8 in 2020 pre-pandemic while demand

continues to rise and is expected to be approx. 185 million lbs in 2020. The spot uranium price is

approx. $33 / lb U 3O8 which is still well below the average all -in global cost of production and

significant price appreciation is needed to justify this production as well as developing new mines

to ensure sustainable and secure supply to meet growing global demand. There are 442 operating

nuclear reactors and 54 new reactors under construction globally with hundreds more planned in

the pipeline. China continues to be at the forefront of demand growth and has the largest reactor

pipeline including 47 operating reactors, 12 under construction and another 212 that have been

ordered, planned or proposed, making up a significant portion of the global pipeline of non -

operating units.

In more recent news, mine closures and production curtailment continue to dominate headlines.

Major production cuts and depleting mine reserves appear to be working their way into the

uranium market and driving prices higher. The two largest producers, Cameco and

KazAtomProm, have announced large supply cuts including Cameco’s suspension of operations

at the world’s largest uranium mines, McArthur River and Cigar Lake, as well as KazAtomProm’s

announcement that it will cut production by 4,000 tU in 2020 . Several uranium mines in Africa

were also impacted by the pandemic adding to the supply disruption for 2020. Several new

uranium holding companies and funds have emerged which have collectively raised hundreds of

millions of dollars to purchase physical material effectively taking further spot supply from

circulation. Lastly, producers like Cameco have been forced to buy uranium directly in the spot

market to fulfill their contract deliveries as their production profiles have decreased.

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 style

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

Historical drill highlights include 4.03% eU 3O8 over 10 metres including 20% eU 3O8over 1.4

metres, and in 2017, Skyharbour announced drill results including 6.0% U3O8 over 5.9 metres

including 20.8% U3O8 over 1.5 metres at a vertical depth of 265 metres. 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.
