Vancouver, BC, March 5, 2018 – IsoEnergy Ltd. (“IsoEnergy” or the “Company”) (TSXV: ISO; OTCQX: ISENF) is pleased to announce that it has intersected a zone of elevated radioactivity during an ongoing core drilling program at its 100% owned Geiger property (the “Property”) in the Eastern Athabasca Basin region of Saskatchewan.   

A zone of elevated radioactivity has been intersected in drill hole GG18-08.  Figure 1 shows the location of the drill hole on the Geiger property.  The zone was intersected within basement pelitic gneiss, approximately 15 metres beneath the base of the Athabasca sandstone.  Radioactivity measured with a 2PGA-1000 total gamma down-hole probe averages 4,500 counts per second (CPS) over 2.1 metres.  The maximum probe value within the interval is just over 14,000 CPS.  Figure 2 is a cross-section showing the location of the mineralization relative to the interpreted geology.  Analysis of the drill core with a hand-held spectrometer indicates the radioactivity is due to uranium, but geochemical analysis is needed for final confirmation.  The drill core has been sampled and geochemical results are pending.

Drill hole GG18-08 is a 50 metre step-out (along strike to the northeast) from historic mineralized drill hole HL-76.  HL-76 intersected 0.65% U3O8 over 0.1 metres in basement gneiss approximately 43 metres beneath the base of the Athabasca sandstone.  GG18-08 is the furthest hole to the northeast along the northeast trending HL11S conductor.  Therefore, the mineralized zone is wide open to the northeast and at depth.  According to historical geophysical surveys, the HL11S conductor might extend up to 2.5 kilometres to the northeast beyond GG18-08.  Drill hole GG18-08 is the seventh of an eight-hole program, which should be completed by March 9^th.

Forward-Looking Information

The information contained herein contains “forward-looking statements” within the meaning of the United States Private Securities Litigation Reform Act of 1995 and “forward-looking information” within the meaning of applicable Canadian securities legislation. “Forward-looking information” includes, but is not limited to, statements with respect to the activities, events or developments that the Company expects or anticipates will or may occur in the future, including, without limitation, planned exploration activities and completion of the acquisition of the Property. Generally, but not always, forward-looking information and statements can be identified by the use of words such as “plans”, “expects”, “is expected”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates”, or “believes” or the negative connotation thereof or variations of such words and phrases or state that certain actions, events or results “may”, “could”, “would”, “might” 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 reasonable terms and in a timely manner and that the acquisition of the Property will be completed on the terms currently agreed to. Although the assumptions made by the Company in providing forward-looking information or making forward-looking statements are considered reasonable by management at the time, there can be no assurance that such assumptions will prove to be accurate.

Forward-looking information and statements also involve known and unknown risks and uncertainties and other factors, which may cause actual events or results in future periods to differ materially from any 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 supplies, failure of equipment to operate as anticipated; accidents, effects of weather and other natural phenomena and other risks associated with the mineral exploration industry, environmental risks, changes in laws and regulations, community relations and delays in obtaining governmental or other approvals.

Although the Company has attempted to identify important factors that could cause actual results to differ materially from those contained in the forward-looking information or implied by forward-looking information, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that forward-looking information and statements will prove to be accurate, as actual results and future events could differ materially from those anticipated, estimated or 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
