IsoEnergy Identifies Additional Uranium Drill Targets at Thorburn Lake
IsoEnergy Identifies Additional Uranium Drill Targets at Thorburn Lake
Vancouver, BC, December 19, 2017 – IsoEnergy Ltd. (“IsoEnergy” or the “Company”) (TSXV: ISO; OTCQX:
ISENF) is pleased to announce that it has completed a program of ground geophysical surveying at its Thorburn
Lake uranium property (the “Property”) in the Eastern Athabasca Basin of Saskatchewan. Compilation and
interpretation of the DC‐Resistivity geophysical data with previous surveys has resulted in the recognition of
additional high priority drill targets on the property.
Steve Blower, Vice President of Exploration commented: “The survey has successfully located new, high priority
drill targets on the unexplored western half of Thorburn Lake that add to an already strong inventory on the
property.”
Thorburn Lake
Thorburn Lake consists of two claims totaling 2,802 hectares and is located seven kilometres east of Cameco
Corp.’s Cigar Lake uranium mine. Figure 1 shows the location of Thorburn Lake relative to the Cigar Lake mine,
other uranium occurrences, and key infrastructure in the area including a powerline and the Cigar Lake to
McClean Lake ore haul road which both traverse the western half of the Property.
Despite the presence of several high‐grade uranium mines and occurrences in the immediate area, only limited
exploration has been completed on the Property to date, most of which has focused on following up weak
mineralization drilled in 2008 and 2011 along the eastern end of the southern property boundary. This
mineralization includes 0.43% U3O8 over 0.6 metres in 2011 drill hole TBN‐11‐05a. Depth to the sub‐Athabasca
unconformity at Thorburn Lake ranges from 290 to 350 metres.
The Survey
A program of 49.5 line‐km of DC‐Resistivity geophysics on grid lines spaced 200 metres apart is now complete.
Figure 1 shows the area that was surveyed, constituting a large portion of the western half of Thorburn Lake.
The program extended geophysical coverage to the southwest of the area surveyed in 2016 and was designed
to initiate exploration on the western half of the property and add drilling targets to the Company’s Thorburn
Lake inventory for potential evaluation by drilling.
The entire western half of Thorburn Lake is essentially unexplored, due in part to the presence of a 138 KV
powerline that supplies power to the entire Eastern Athabasca region. The powerline effectively masks a large
area of the property from electromagnetic geophysical surveying, a common tool for locating drill targets in
the Athabasca basin. DC‐Resistivity surveying, however, is much less affected by powerline noise and is at least
equally capable of locating drill targets.
Compilation and interpretation of the data with prior geophysical surveys has resulted in the recognition of
target areas that warrant evaluation by drilling. The target areas are discrete resistivity low anomalies in the
basement that coincide with magnetic lineaments. These features may represent areas of hydrothermal
alteration along major structures that could be related to basement hosted uranium mineralization.

All of the Thorburn Lake target areas have been scored and ranked against all other IsoEnergy drill targets
and will be evaluated in due course as priorities, market conditions and budgets permit, possibly as early as
H2 2018.

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
