Skyharbour Intersects High Grade Uranium in Multiple Drill Holes Including 9.12% U3O8

over 1.4m at Newly Discovered Maverick East Zone as well as 5.29% U3O8 over 2.5m at

Main Maverick Zone on the Moore Uranium Project

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

SC1P) (the “ Company”) is pleased to announce the results from its first phase, winter 2017

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

15 kilometres east of Denison Mine’s Wheeler River project and near regional infrastructure on

the southeast side of the Athabasca Basin, Saskatchewan. Multiple drill holes intersected high

grade uranium mineralization at the 4 kilometre long Maverick structural corridor. High grade

results include 9.12% U 3O8 over 1.4 metres within an interval returning 4.17% U 3O8 over 4.5

metres in hole ML-202; 5.29% U3O8 over 2.5 metres within an interval returning 2.99% U3O8 over

5.0 metres in hole ML-200; 2.25% U3O8 over 3.0 metres in hole ML-208, and previously reported

20.8% U3O8 over 1.5 metres within an interval returning 6.0% U3O8 over 5.9 metres in hole ML-

199. This high grade mineralization within the Maverick corridor is relatively shallow ranging from

250 metres to 275 metres vertical depth. Also of note is that hole ML-202 represents the discovery

of a new high grade mineralized lens on the corridor.

Highlights:

 Hole ML-202 at the Maverick East Zone returned 1.79% U3O8 over 11.5 metres from 266.0

to 277.5 metres downhole including 4.17% U 3O8 over 4.5 metres and 9.12% U 3O8 over

1.4 metres; this is a newly discovered high grade mineralized lens on the Maverick corridor

and illustrates the strong discovery potential of additional high grade lenses along strike.

 Hole ML-208 at the Main Maverick Zone returned 2.25% U3O8 over 3.0 metres from 266.8

to 269.8 metres.

 Previously reported drill hole ML -199 at the Main Maverick Zone intersected high grade

uranium mineralization containing 6.0% U3O8 over 5.9 metres, from 261.6 to 267.5 metres

depth including 20.8% U3O8 over 1.5 metres from 264.0 to 265.5 metres.

 This first phase drill program totaled 5,450 metres in 15 holes testing the Maverick corridor;

the kno wn unconformity -hosted high grade mineralization at the Maverick corridor is

relatively shallow at 250 metres to 275 metres vertical depth.

 Only 1.5 kilometres of the total 4 kilometre long Maverick corridor have been

systematically drill tested leaving robust discovery potential along strike as well as at depth

in the underlying basement rocks which have seen limited drill testing historically.

 Given the success of the first phase of d rilling at Moore, planning is currently underway

for a summer drill program with news and details forthcoming; the Company is fully funded

for this upcoming drill program with over $3.7 million in the treasury.

Jordan Trimble, President and CEO of Skyharbour Resources, states: “The first phase of drilling

at Moore has far exceeded our expectations and we will be commencing a summer drill program

in the coming months to follow up on these results. The presence of shallow, high grade uranium

mineralization in seven of the fifteen holes is very encouraging not to mention that all of the holes

drilled to target intersected uranium mineralization in this program. We are discovering new, high

grade mineralized lenses along strike from the Main Maverick Zone which clearly illustrates the

robust, underlying geolog ical potential of the Moore Project . The Maverick corridor is over 4

kilometres long yet only 1.5 kilometres have been systematically drilled with most of this drilling

and known high grade uranium hosted at or near the unconformity leaving strong discovery

potential along strike but also at depth in the basement rocks. The Company is fully funded to

complete multiple future drill program s, including the upcoming summer program, which will

provide ample news flow for the remainder of the year as we continue to value -add the project

using a systematic and proven exploration methodology augmented by innovative field techniques

and new geological analyses.”

Winter 2017 Drill Program Summary and Upcoming Summer 2017 Drill Program Plans:

This recently completed drill program totaled 5,450 metres in fifteen holes with most holes drilled

to between 200 metres and 350 metres depth except for one hole drilled deeper to 468 metres.

The program was focused on the Maverick structural corridor and tested gaps as well as the

margins of the Main Maverick Zone lens. Other targets tested include d the Maverick East Zone,

the Goose Zone, the Maverick West Zone and the Maverick South Zone. Of the fifteen holes

drilled, seven had high grade mineralization over 1.0% U3O8, thirteen were mineralized and two

had no significant mineralization but only due to drill hole deviation.

The highest grade intercept was from hole ML-199 which returned 6.0% U3O8 over 5.9 metres

from 261.6 to 267.5 metres downhole including 20.8% U3O8 over 1.5 metres (see news release

Feb. 27th, 2017). The final assay results from two holes for which only calculated probe equivalent

results were previously reported have been significantly upgraded in light of the analytical results.

Hole ML-200 returned 1.62% U3O8 over 9.5 metres from 269 .0 to 278.5 metres downhole

including 2.99% U3O8 over 5.0 metres and including 5.29% U3O8 over 2.5 metres. Hole ML-208

located on the western portion of the Main Maverick Zone returned 2.25% U3O8 over 3.0 metres

from 266.8 to 269.8 metres downhole.

Hole ML-202, drilled at the newly discovered Maverick East Zone, returned 1.79% U3O8 over 11.5

metres from 266.0 to 277.5 metres downhole including 4.17% U3O8 over 4.5 metres and including

9.12% U3O8 over 1.4 metres. This new high grade lens exemplifies the potential for high grade

uranium mineralization to be discovered between widely spaced previous drill holes on the 4

kilometre long Maverick corridor.

Drill hole ML -207 was drilled to a depth of 468 metres in the Maverick South Zone to test for

deeper basement hosted mineralization. As one of the few exploratory holes drilled to test the

basement potential at the Moore Project, this hole intersected anomalous uranium mineralization

with coincident boron enr ichment several metres beneath the unconformity. This is highly

3

encouraging and demonstrates the strong discovery potential at depth in the underlying

basement rocks throughout the Moore Project.

inset_20170515_v2.pdf

Also of note, Hole ML -205 was drilled in a separate high grade mineralized lens known as the

Goose Zone located approx. 500 metres E -NE of the Main Maverick Zone and returned 1.80%

U3O8 over 1.6 metres within 0.47% U3O8 over 10.4 metres from 275.1 to 285.5 metres downhole.

The Goose Zone is still open along strike and at depth in the basement rock. Further along strike

one kilometre to the E-NE (approx. 1.5 kilometres from the Main Maverick Zone), the Viper Zone

represents a high priority target going forward with limited historical drilling having discovered

shallow uranium mineralization. The Company is planning to drill test this area in th e upcoming

summer drill program along with the Maverick Zone and other regional targets. Details on this drill

program are forthcoming.

Only 1.5 kilometres of the total 4 kilometre long Maverick corridor has been systematically drill

tested leaving strong discovery potential along strike as well as at depth in the underlying

basement rocks which have seen limited drill testing historically. Furthermore, there are ten other

regional drill targets on the Moore Project in which historical drilling has discovered uranium

mineralization including the Pukapuka, Nutana, Otter Grid, Avalon, Venice and Rarotonga Zones.

All of these zones remain open along strike and at depth with only limited and widely spaced

exploratory drill testing having been conducted historically.

Geological Description of Winter 2017 Drill Program:

Main Maverick Zone:

Six holes tested the Main Maverick Zone lens during this winter’s program, four of which

intersected high grade uranium mineralization. This includes holes ML -199 and ML -200

(discussed above), as well as hole ML-208 which was drilled in the western half of the lens and

intersected high grade uranium mineralization just below the unconformity in clay altered and

replaced graphitic pelites. This hole returned 2.25% U3O8 over a 3.0 metre interval from 266.8 to

269.8 metres downhole. Hole ML-213 drilled in the eastern half of the lens intersected high grade

uranium mineralization within the sandstone above the unconformity overlying clay altered to

replaced granite. This hole returned 0.76% U3O8 over a 10.4 metre interval from 266.2 to 276.6

metres downhole and included a higher grade interval of 1.56% U3O8 over 3.5 metres. Hole ML-

213 also contained highly anomalous levels of pathfinder elements in both the sandstone and

basement rocks, specifically As, Co, Cu, Ni, Pb, Zn and V, with copper being particularly enriched.

A 1.0 metre interval in the sandstone returned 3.4% Cu approx imately ten metres above the

unconformity. Holes ML-201 and ML-203 deviated from their targeted zones and did not intersect

significant uranium mineralization.

Maverick East Zone:

Four holes drill tested the new ly discovered Maverick East Zone lens with all four holes

intersecting uranium mineralization. Hole ML-202 intersected high grade uranium mineralization

in a previously untested area approximately 75 metres east-northeast of the Main Maverick lens.

This hole returned 1.79% U3O8 over 11.5 metres from 266 to 277.5 metres downhole including

4.17% U3O8 over 4.5 and including 9.12% U3O8 over 1.4 metres. The mineralization straddles the

unconformity and extends into the clay-replaced and altered weakly graphitic pelitic and granitic

basement rocks. Three additional holes tested the lens including hole ML-211 which returned

0.13% U3O8 over 8.5 metres a long with highly anomalous levels of pathfinder elements in both

4

the sandstone and basement rocks . Hole ML- 212 returned 0.19% U3O8 over 3.4 metres and

hole ML-210 returned 0.10% U3O8 over 1.0 metre.

Goose Zone:

The Goose Zone (formerly 527 Zone) is located approximately 500 metres northeast of the Main

Maverick lens. Three holes tested this area and the most significant results were obtained from

ML-205 which intersected 0.47% U3O8 over 10.4 metres from 275.1 to 285.5 metres downhole

including 1.80% U3O8 over 1.6 metres. The mineralization is primarily in the clay altered and

replaced pelites and granites at and just beneath the unconformity. Hole ML-204 intersected

0.06% eU3O8 over 5.5 metres in clay altered pelites five metres below the unconformity while hole

ML-206 intersected 0.09% U3O8 over 0.5 metres.

Maverick West Zone:

Hole ML-209 tested a resistivity low that correlated with the Maverick conductor system

approximately 750 metres west of the Main Maverick lens. It intersected strongly altered and

structurally disrupted sandstone and basement lithologies as well as anomalous uranium

mineralization accompanied by anomalous Pb values in the basement rock ten metres below the

unconformity. This zone has seen limited historical drill testing and remains open along strike and

at depth.

Maverick South Zone:

Hole ML-207 was collared 100 metres south of the Maverick conductor system and was drilled to

a depth of 468 metres in the Maverick South Zone to test for deeper basement hosted

mineralization. As one of the few exploratory holes drilled to test the basement potential at the

Moore Project, th is hole intersected anomalous uranium mineralization with coincident boron

enrichment several metres below the unconformity in faulted graphitic pelites . This is highly

encouraging and illustrates the strong discovery potential at depth in the underlying basement

rocks throughout the Moore Project.

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, approx. 15 kilometres east of Denison’s Wheeler River project, and 39 kilometres south of

Cameco’s McArthur River uranium mine. Unconformity style uranium minera lization 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 starting at a depth of

265 metres in hole ML-61. 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 accessible via winter and ice roads which simplifies logistics and lowers costs.

Skyharbour holds an extensive portfolio of uranium and thorium exploration projects in

Canada's Athabasca Basin and is well positioned to benefit from improving uranium ma rket

fundamentals with five drill -ready projects. In July 2016, Skyharbour acquired an option from

Denison Mines, a large strategic shareholder of the Company, to acquire 100% of the Moore

Uranium Project which is located approx. 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 with

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

vertical depth of 265 metres. Skyharbour recently signed option agreements with AREVA

Resources Canada and Azincourt Uranium whereby AREVA and Azincourt can earn in 70% on

the Preston Project through a combined $9,800,000 in total exploration expenditures, as well as

$1,700,000 in total cash payments and 4,500,000 Azincourt shares. Preston is a large,

geologically prospective property proximal to Fission Uranium’s Triple R deposit as well as

NexGen Energy’s Arrow deposit. The Company also owns a 100% interest in the Falcon Point

Uranium Project on the eastern perimeter of the Basin which contains an NI 43 -101 inferred

resource totaling 7.0 million pounds of U3O8 at 0.03% and 5.3 million pounds of ThO2 at 0.023%.

The project also hosts a high grade surface showing with up to 68% U3O8 in grab samples from

a massive pitchblende vein, the source of which has yet to be discovered. The Company’s 100%

owned Mann Lake Uranium project on the east side of the Basin is strategically located adjacent

to the Mann Lake Joint Venture operated by Cameco, where high grade uranium mineralization

was recently discovered. Skyharbour’s goal is to maximize shareholder value through new

mineral discoveries, co mmitted long -term partnerships, and the advancement of exploration

projects in geopolitically favourable jurisdictions.
