IsoEnergy Begins DC‐Resistivity Geophysical Survey at the Larocque East Uranium Property
IsoEnergy Begins DC‐Resistivity Geophysical Survey at the Larocque
East Uranium Property
Vancouver, BC, April 24, 2019 – IsoEnergy Ltd. (“IsoEnergy” or the “Company”) (TSXV: ISO; OTCQX: ISENF) is
pleased to announce that a 53 line‐km program of DC‐Resistivity (DC‐Res) geophysical surveying has begun on
its 100% owned Larocque East property (the “Property”). Larocque East is home to the Hurricane zone, a new
discovery of high‐grade uranium mineralization.
The Hurricane zone is a body of shallow (330m below surface), h igh‐grade uranium mineralization located on
the west side of the Larocque East property (Figure 1). The Co mpany recently completed the first follow‐up
drilling program after the discovery intersection in July 2018. Eleven of 12 drill holes in the follow‐up winter
campaign intersected significant uranium mineralization. Hurri cane now measures 150m (long) x 38m (wide)
and is up to 8.5m thick. The zone is open on all five sections drilled to date and along strike in both directions.
The Company remains fully funded for a follow‐up drilling campaign that is planned for the summer.
Steve Blower, Vice President, Exploration commented: “The next drilling campaign at Hurricane will include
more aggressive step‐outs, and will therefore benefit from surv ey results that will help to locate conductive
graphitic stratigraphy and associated alteration zones. The survey will also improve our understanding of
Hurricane zone stratigraphy extensions further to the east, and other conductor systems south of Hurricane.”
DC‐Res Survey
There are three main objectives for the survey. The first is to fingerprint the key graphitic horizons that control
mineralization at Hurricane and locate them immediately east of the Hurricane zone to aid step‐out drill holes
planned for the summer of 2019. Secondly, as the survey covers over five kilometres of the wide open Larocque
conductor system east of Hurricane, it will be used to guide future exploration drilling programs targeting
additional mineralization along this fertile belt. Finally, the survey will more accurately locate a poorly
understood conductor system 2km south of Hurricane. This southern conductor system is parallel to the
Hurricane trend, has a possible strike extent of 2.3km on the P roperty and has never been drilled within the
Property boundaries.
A total of 53 line‐km of surveying will be completed along surv ey lines spaced 200‐400m apart. The crew has
mobilized to IsoEnergy’s Larocque Lake camp and surveying has b egun. The survey will take approximately
one month to complete. Figure 2 shows the area to be surveyed.
Larocque East
Larocque East consists of 6 mineral claims totaling 3,200 hectares and was purchased in May, 2018. 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 p r o pe r t y a n d i s 3 5 k i l o m e t r e s n o r t h w e s t o f
Orano Canada’s McClean Lake uranium mine and mill.
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 a neighbouring property to the southwest of Larocque East. The
c l o s e s t o f t h e s e t o L a r o c q u e E a s t a r e t h e L a r o c q u e L a k e a n d L a rocque North zones, which are located 6.5
kilometres and 0.4 kilometres, respectively, to the southwest of the western Larocque East property boundary.
Drilling at Cameco Corp.’s Larocque Lake zone has returned hist orical intersections of up to 29.9% U 3O8 over
7.0 metres in drill hole Q22‐040. Drilling at the Larocque North zone has returned intersections of up to 2.05%
U3O8 over 0.6 metres in drill hole Q22‐16. Like the nearby Geiger property, Larocque East is located adjacent
t o t h e W o l l a s t o n ‐ M u d j a t i k t r a n s i t i o n z o n e ‐ a m a j o r c r u s t a l s u ture related to most of the major uranium
deposits in the eastern Athabasca Basin. Importantly, the sand stone 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 dr ill holes have intersected weak uranium
mineralization at other locations on the Larocque East property to date.

Qualified Person Statement
The scientific and technical information contained in this news release was prepared by Andy Carmichael,
P.Geo., IsoEnergy’s Senior Geologist, who is a “qualified perso n” (as defined in National Instrument 43‐101 –
Standards of Disclosure for Mineral Projects). Mr. Carmichael has verified the data disclosed. This news release
refers to properties other than those in which the Company has an interes t. Min eralizatio n o n tho s e o ther
properties is not necessarily indicative of mineralization on t he Company’s properties. An RS‐125 hand‐held
spectrometer was used to verify that the radioactivity is due to uranium. As the drill holes reported herein are
vertical or near‐vertical, and the mineralization is interprete d to be horizontal, the true thickness is expected
to be within 90% of the cored intervals.
