Skyharbour Partner Company Terra Clean Energy Completes First Three Drill Holes on

Fraser Lakes Uranium Deposit at the South Falcon East Uranium Project

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

SC1P) (“Skyharbour” or the “Company”) is pleased to announce that partner company Terra Clean

Energy Corp. (“Terra”, previously Tisdale Clean Energy) has completed its first three drill holes at

the South Falcon East Uranium Project (the “Property”) which hosts the Fraser Lakes B Uranium

Deposit. The program will continue throughout March and is expected to consist of over 2,000 metres

of drilling. The South Falcon East Project lies 18 km outside the edge of the Athabasca Basin,

approximately 50 km East of the Key Lake uranium mill and former mine. Skyharbour optioned the

Project to Terra and under the Option Agreement assuming the 75% interest is earned, Terra will

fund exploration expenditures totaling CAD $10,500,000, as well as pay Skyharbour CAD

$11,100,000 in cash of which $6,500,000 can be settled for shares in the capital of T erra over the

earn-in period.

Terra is currently conducting a 2,000m - 2,200m helicopter supported drill program at the Property.

Three diamond drill holes have been completed on the Fraser Lakes B Uranium Deposit, for a total

of 802m, and a fourth hole is in progress.

“We are extremely encouraged by the results of the first three drill holes as we continue to see

mineralization in each of the holes as well as what we believe to be an expansion of the deposit to

the North. As stated below, Hole SF063 returned a continuous mineralized zone of pegmatites from

173 metres to 224 metres with some decent grades.” Based on the initial results from Hole SF063

we have decided to reorganize the remaining metres of this program to focus on further defining this

new area of interest and chasing clay alteration not yet seen on the property to date, with hopes of

finding a new high-grade unconformity uranium deposit,” said Greg Cameron CEO of the Terra Clean

Energy.

Hole SF063 was planned to examine an interpreted cross fault offsetting the mineralization and

geology on the east end of the Fraser Lakes B Uranium Deposit. This hole was drilled to a depth of

393 metres and intersected multiple structures and a 51 -metre wide interval of mineralized granitic

pegmatites and zones within altered and graphitic pelitic gneiss. Highlights include 0.03% eU 3O8

over 12.0m from 173.55m to 185.55m, including 0.06% eU3O8 over 0.7m from 180.35m to 181.05m,

as well as 0.03% eU3O8 over 3.0m from 213.65 m to 216.65m, including 0.07% eU 3O8 over 0.5m

from 215.95m to 216.45m.

The first structure intersected from 18m to 47.5m contained zones of intense clay alteration typically

found in relation to unconformity uranium deposits. The presence of this alteration is a good

indication that hydrothermal fluids suitable for deposition of higher -grade uranium mineralization

moved through the rocks. The second structure from 306 m to 315m is a brecciated pelitic gneiss

situated between two intervals of Archean gneiss. This structure is interpreted to be responsible for

the geological offset being targeted. This will assist in updating the target model in this area. The

intersections of a clay altered structure and a thick sequence of minera lized pegmatites and pelitic

gneiss have expanded the mineralization and improved the prospectivity on the east end of the

Fraser Lakes B Uranium Deposit.

“The results from the drilling so far are very encouraging,” commented Trevor Perkins, Vice President

of Exploration for Terra Clean Energy. “The first two holes have shown that the deposit is still open

down dip to the north and northwest. Hole SF0063 has shown that there is significant potential for

upgrading the deposit on the east end. We are excited to see where this can lead”, continued Mr.

Perkins.

Drilling is continuing with one hole in progress at the T -Bone Lake target area to examine the

conductive package and alteration intersected in the area in historical drilling. Pad preparation is

underway to return to the target around hole SF0063 and follow up on the clay alteration and

pegmatites. Efforts will be made to follow the alteration and pegmatites to where they intersect, as

this should be an area of fluid pooling and upgrading of mineralization within the deposit.

The first hole in the program, h ole SF061 was planned to test for a down dip extension of

mineralization intersected in hole FP-15-05 and was drilled to a depth of 209m. Drilling intersected

a 35m interval containing multiple mineralized granitic pegmatites and zones within altered and

graphitic pelitic gneiss. The most notable zone returned an equivalent grade of 0.02% eU 3O8 over

2.2 m from 150.25 m to 152.45m, including 0.05% eU 3O8 over 0.6m from 151.65 m to 152.25m.

Historical diamond drill hole FP -15-05 was drilled by Skyharbour in 2015 in this area and returned

multiple zones of mineralization over a 14m interval, including 6m of 0.10% U3O8 including 2.0m of

0.165% U3O8 from 135m depth and 2.5m of 0.172% U3O8 from 145m depth.

Hole SF062 was planned to test for an along strike extension of mineralization intersected in holes

FP-15-05 and SF0061 and was drilled to a depth of 200m. Drilling intersected a 21m interval

containing multiple mineralized granitic pegmatites and zones within altered and graphitic pelitic

gneiss. The most notable zone returned an equivalent grade of 0.03% eU 3O8 over 2.2 m from

141.75m to 144.15 m, including 0.05% eU3O8 over 0.4m from 143.15m to 143.55 m.

While both of these holes extended the mineralization down dip and along strike to the north and

northwest, they did not intersect the higher grades encountered in hole FP-15-05. This is due to the

potential variability within the pegmatite swarm. As long as the mineralized pegmatites are present,

higher grades will be encountered within the overall mineralized zone.

South Falcon East Project Summary:

The South Falcon East Project is a uranium exploration project in the southeast Athabasca Basin

and covers approximately 12, 464 hectares. It lies 18 kilomet res outside the Athabasca Basin,

approximately 50 kilometres east of the Key Lake Mine. Historical exploration at the South Falcon

East Project identified an area of U-Th-REE mineralization at the Fraser Lakes Zone B over an area

comprising 1.5 km by 0.5 km along an antiformal fold nose cut by an east-west dextral ductile-brittle

cross-structure adjacent to a 65 km long EM conductor.

QA/QC, Radiometric Equivalent Grades and Spectrometer Readings:

All drill intervals above are downhole length and sampling procedures and QA/QC protocols for

geochemical results as well as a description of downhole gamma probe grade calculations and

protocols are below. All drill core samples are shipped to the Saskatchewan Research Council

Geoanalytical Laboratories (“SRC”) in Saskatoon, Saskatchewan under the care of Terra personnel

for preparation, processing, and multi -element analysis by ICP -MS and ICP -OES using total

(HF:NHO3:HClO4) and partial digestion (HNO3:HCl), boron by fusion, and U3O8 wt% assay by ICP-

OES using higher grade standards. Assay samples are chosen based on visual inspection, downhole

probing radiometric equivalent uranium grades and scintillometer (Radiation Solu tions RS -125)

peaks. Assay sample intervals comprise 0.5 to 1.0 metre continuous half-core split samples over the

mineralized interval. These samples may also be selected for density determination using the lost

wax method. With all assay samples, one half of the split sample is retained and the other sent to

the SRC for analysis. The SRC is an ISO/IEC 17025/2005 and Standards Council of Canada certified

analytical laboratory. Blanks, standard reference materials, and repeats are inserted into the sample

stream at regular intervals by Terra and the SRC in accordance with Terra’s quality assurance/quality

control (QA/QC) procedures. Geochemical assay data are subject to verification procedures by

qualified persons employed by Terra prior to disclosure.

During active exploration programs drillholes are radiometrically logged using calibrated downhole

Mount Sopris 4OTGU or 2GHF probes of varying sensitivities which collect continuous readings

along the length of the drillhole. Preliminary radiometric equiv alent uranium grades (“eU 3O8”) are

then calculated from the downhole radiometric results. The probe is calibrated using an algorithm

calculated from the calibration of the probe at the Saskatchewan Research Council facility in

Saskatoon and from the compar ison of probe results against geochemical analyses. In the case

where core recovery within a mineralized intersection is poor or non-existent, radiometric grades are

considered to be more representative of the mineralized intersection and may be reported i n the

place of assay grades. Radiometric equivalent probe results are subject to verification procedures

by qualified persons employed by Terra prior to disclosure.
