IsoEnergy Intersects 1.6% U3O8 over 10.5m in Drill Hole LE19‐28,
Including 12.6% U3O8 over 1.0m
Vancouver, BC, October 1, 2019 – I s o E n e r g y L t d . ( “IsoEnergy” or the “Company”) (TSXV: ISO; OTCQX: ISENF) is
pleased to provide final assay results from its recently completed summer drilling program on the Hurricane zone at
the Larocque East property. Highlights include assay results f rom drill holes LE19‐28 and LE19‐29. The Hurricane
zone is located on the Company’s 100% owned Larocque East prope rty (the “Property”) in the Eastern Athabasca
Basin of Saskatchewan (Figure 1).
Assay Highlights
Chemical assays received for drill hole LE19‐28, comprising 1.6% U3O8 over 10.5m, including 12.6% U3O8
over 1.0m
Chemical assays received for drill hole LE19‐29, comprising 4.6% U3O8 over 2.0m, including 16.6% U3O8
over 0.5m
Steve Blower, Vice President of Exploration commented: “These final assay results from our 17‐hole summer drilling
program provide further evidence of the strength and continuity o f t h e H u r r i c a n e z o n e . D a t a c o m p i l a t i o n a n d
interpretation is on‐going and preparations are already underwa y for a winter drilling program that is planned to
begin in January. I’m grateful for the excellent work completed by our Technical team and our primary contractors
Bryson Drilling, Little Rock Enterprises and Discovery Int’l Geophysics.”
Craig Parry, CEO commented: “We are very pleased to report these strong final assay results from our summer drill
program from Hurricane, the first high grade‐uranium discovery g l o b a l l y f o r s o m e ye a r s . T h e r e s u l t s c o n t i n u e t o
confirm the size and grade potential of the deposit and positio n IsoEnergy well for the next drill campaign. These
results come at an important time for the uranium exploration and mining sector. The larger number of mine
closures over the past two years have started to have a signifi cant impact on the uranium market. After a hiatus of
six months, in recent weeks we have seen a return of activity t o the uranium spot market and the price has once
again started rising, from $24.5 to $25.60/lb. over the past week. We expect significant renewed buying in the spot
market over coming months and this has the potential to have further positive impact on the uranium price. Against
this market backdrop we look forward to recommencing drilling and reporting further results from Hurricane during
the coming winter.”
Drill Hole LE19‐28 Assays (Section 4660E)
Drill hole LE19‐28 (Figures 2 and 3) was completed 25m to the e ast of the LE19‐16A section. LE19‐28 intersected a
10.5m interval (321.0‐331.5m) of strong uranium mineralization t h a t a v e r a g e s 1 . 6 % U3O8 and includes a 1.0m
subinterval that averages 12.6% U3O8. Mineralization straddles the sub‐Athabasca unconformity. Drill hole LE19‐28
is the only drill hole completed on this section to date, and therefore the zone is wide open for expansion.
Drill Hole LE19‐29 Mineralization (Section 4610E)
Completed on section 4610E, 25m west of the LE19‐16A section, d rill hole LE19‐29 (Figures 2 and 4) intersected a
2.0m interval (337.5‐339.5m) of strong uranium mineralization that averages 4.6% U3O8 and includes a 0.5m
subinterval that averages 16.6% U3O8. The drill hole is interpreted to have over‐shot the strongest part of the
Hurricane zone mineralization and the zone is wide open for expansion to the north on this section.
Next Steps
With the receipt of final assays, data compilation and interpretation are well underway. Plans are being made for a
large winter drilling program expected to begin in January, 202 0, with winter road preparation beginning in
December, 2019. Winter drilling in 2020 is likely to have two objectives; (1) complete sections and in‐fill large gaps
in the current footprint, and (2) extend the Hurricane zone strike length to the east with the aid of geophysical
targets generated by the recently completed DC‐Resistivity geophysical survey.

Figure 2 – Drill Hole Location Map
Figure 3 – Cross Section 4660E
Figure 4 – Cross Section 4610E
The Larocque East Property and the Hurricane Zone
The 100% owned Property consists of 20 mineral claims totaling 8,371ha 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‐kilomet re‐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 occurrence s on Cameco Corp.’s neighbouring property to the
southwest of Larocque East. The Hurricane zone was discovered in July, 2018 and was followed up with a 12‐hole
drilling campaign in the winter of 2019 and a recently complete d 17‐hole summer drilling campaign. Dimensions
are currently 500m along‐strike, 40m wide and up to 10m thick. The zone is open for expansion along‐strike and on
most sections. Mineralization is polymetallic and commonly straddles the sub‐Athabasca unconformity 320m below
surface. 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 the Property 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 Property to date.
