IsoEnergy Expands Larocque East Uranium Property Through Staking

Vancouver, BC, June 5, 2019 – IsoEnergy Ltd. (“ IsoEnergy” or the “ Company”) (TSXV: ISO; OTCQX: ISENF ) is

pleased to announce it has expanded its 100% owned Larocque East property (the “ Property”), home to the

Hurricane uranium zone. The Hurricane zone is a new discovery of high-grade uranium mineralization located

in the prolific eastern Athabasca Basin, Saskatchewan.

Through staking on May 28th, 2019, the Company added a contiguous parcel of mineral claims totalling 4,850ha

(Figure 1). This increases the total area of the Larocque East property to 8,371ha. The newly staked ground

encompasses an 8km-long east-west oriented magnetic low corridor that includes approximately 4km of

electromagnetic (EM) conductors known as the Bell North trend. The conductors have been the focus of wide

spaced reconnaissance uranium drilling campaigns as recently as 2014. Results from this drilling include weak

uranium mineralization (0.11% U3O8 over 0.5m) at the unconformity in drill hole BL14-16, located 11km west

of the Hurricane zone. Additionally, the presence of significant sandstone and basement alteration associated

with faulted graphitic basement rocks suggests that there is significant discovery potential remaining on the

Bell North trend.

Steve Blower, Vice President, Exploration commented: “I’m very pleased that we’ve added these claims to our

Larocque East property at very little cost. Our technical team did a terrific job of evaluating the exploration

potential, and then executing a solid staking plan in a competitive situation. The sparse nature of the drilling

on the EM conductors, combined with anomalous geochemistry and encouraging geology in the drill holes

reminds me of the original Larocque East property when it was acquired in 2018, before the Hurricane zone

was discovered.”

Craig Parry, Chief Executive Officer commented: “This acquisition of additional prospective claims contiguous

with the Larocque East property is another example of executing our strategy to expand our footprint of high-

potential uranium exploration tenure in the eastern Athabasca Basin, the infrastructure-rich home of the

world’s highest-grade uranium mines.”

Larocque East

Larocque East now consists of 20 mineral claims totaling 8,371ha. The original portion was purchased in May,

2018 before being expanded by the staking reported herein. The Property is owned 100% by IsoEnergy and is

not encumbered by any royalties or other interests. Larocque East is immediately adjacent to the north end

of IsoEnergy’s Geiger property and is 35 kilometres northwest of Orano Canada’s McClean Lake uranium mine

and mill.

Along with other target areas, the Property covers a 15-kilometre-long northeast extension of the Larocque

Lake conductor system; a trend of graphitic metasedimentary basement rocks that is associated with significant

uranium mineralization at the Hurricane zone, and in several occurrences on Cameco Corp.’s neighbouring

property to the southwest of Larocque East. The Hurricane zone was discovered in July, 2018 and was recently

followed up with a 12-hole drilling campaign in the winter of 2019. Eleven of those 12 drill holes intersected

substantial uranium mineralization, including 10.4% U 3O8 over 3.5m in drill hole LE19-02 and 3.2% U 3O8 over

8.5m in drill hole LE19-12. Drilling at Cameco Corp.’s Larocque Lake zone on the neighbouring property to the

southwest has returned historical intersections of up to 29.9% U3O8 over 7.0 metres in drill hole Q22-040. Like

the nearby Geiger property, Larocque East is located adjacent to the Wollaston-Mudjatik transition zone - a

major crustal suture related to most of the major uranium deposits in the eastern Athabasca Basin.

Importantly, the sandstone cover on Larocque East is thin, ranging between 140 metres and 330 metres in

previous drilling. In addition to the Hurricane zone discovery, four historical drill holes have intersected weak

uranium mineralization at other locations on the Larocque East property to date.

Stock Option Grant

The Company has also granted 100,000 incentive stock options to a consultant of the Company (the “Options”)

pursuant to the Company’s Stock Option Plan. The Options were granted on June 5, 2019 (the “Grant Date”),

are exercisable at a price of $0.50, and have a term of five years vesting in equal quarterly installments

commencing on the three-month anniversary of the Grant Date. All Options issued are subject to TSXV

acceptance.

or “will be taken”, “occur” or “be achieved” or the negative connotation thereof.

Such forward-looking information and statements are based on numerous assumptions, including among

others, that the results of planned exploration activities are as anticipated, the price of uranium, the

anticipated cost of planned exploration activities, that general business and economic conditions will not

change in a material adverse manner, that financing will be available if and when needed and on

reasonable terms, that third party contractors, equipment and supplies and governmental and other

approvals required to conduct the Company’s planned exploration activities will be available on

projections of future events or results expressed or implied by such forward-looking information or

statements, including, among others: negative operating cash flow and dependence on third party

financing, uncertainty of additional financing, no known mineral reserves or resources, the limited

operating history of the Company, the influence of a large shareholder, alternative sources of energy and

uranium prices, aboriginal title and consultation issues, reliance on key management and other

personnel, actual results of exploration activities being different than anticipated, changes in exploration

programs based upon results, availability of third party contractors, availability of equipment and

intended. Accordingly, readers should not place undue reliance on forward-looking statements or

information. The Company undertakes no obligation to update or reissue forward-looking information

as a result of new information or events except as required by applicable securities laws
