IsoEnergy Reports Geochemical Results From Geiger Property Drilling
IsoEnergy Reports Geochemical Results From Geiger Property Drilling
Vancouver, BC, April 26, 2018 – IsoEnergy Ltd. (“IsoEnergy” or the “Company”) (TSXV: ISO; OTCQX: ISENF) is
pleased to report analytical geochemistry results from samples collected from drill holes GG18-08 and GG18-
09 during a recently completed core drilling program at its 100% owned Geiger property (the “Property”) in
the Eastern Athabasca Basin region of Saskatchewan. Highlights include a sample containing 0.35% U3O8 over
0.2 metres in drill hole GG18 -08, within a larger 2.0 metre interval (above a cutoff of 100 ppm U 3O8) that
averages 0.11% U 3O8 from 271.2 to 273.2 metres. Additionally, drill hole GG18 -09 returned a 15.0 metre
interval (also above a cutoff of 100 ppm U3O8) that averages 0.03% U3O8 from 207.0 to 222.0 metres. Both drill
holes also intersected elevated uranium pathfinder elements.
Drill Hole GG18-08
Designed to evaluate extensions of basement hosted mineralization in historic drill hole HL -76 (0.65% U 3O8
over 0.1 metre), drill hole GG18-08 was completed as a 50 metre step -out along-strike to the northeast (see
the IsoEnergy news release dated March 5, 2018 ). It intersected 2.0 metres (271.2-273.2 metres) of 0.11%
U3O8, 2,227 ppm V, 580 ppm Ni, 407 ppm Co, and 1.5 g/t Ag. The interval includes 0.2 metres (271.2 -271.4
metres) of 0.35% U3O8, 9,320 ppm V, 2,060 ppm Ni, 1,560 ppm Co, and 5.9 g/t Ag. Uranium mineralization in
drill hole GG 18-08, like that in drill hole HL -76, is basement hosted . The sub-Athabasca unconformity was
intersected at 256.3 metres. The intersection in GG18-08 is open in several directions, including down-dip, up-
dip to the unconformity, and along-strike to the northwest.
A separate zone of high grade base metal mineralization was also intersected in the basement, consisting of
0.7 metres (400.1-400.8 metres) of 5.14% Zn, 0.10% Pb and 2.0 g/t Ag. It is unclear whether the base metal
interval is related to the uranium mineralizing event.
Drill Hole GG18-09
Drill hole GG18-09 was designed to evaluate extensions of basement hosted uranium mineralization in historic
drill hole HL-50 (2.7% U3O8 over 1.2 metres), located approximately 1.7 kilometres southwest of GG18-08.
The uranium mineralized interval in drill hole GG18 -09 is much thicker than GG18 -08 and straddles the sub -
Athabasca unconformity. Within the 19.3 metre interval of elevated radioactivity reported previously (see the
IsoEnergy news release dated March 13, 2018), a 15.0 metre interval (207.0 to 222.0 metres) averages 0.03%
U3O8, 2,600 ppm Cu, 998 ppm Ni, 943 ppm Zn and 2.4 g/t Ag. Thi s broad interval includes individual samples
with up to 14,700 ppm Cu, 3,130 ppm Ni, 407 ppm Co, 3,670 ppm Zn and 6.4 g/t Ag.
A second, narrower zone of uranium mineralization was intersected deeper in the basement. It consists of a
0.7 metre interval that averages 0.02% U3O8 and 795 ppm Cu from 251.8-252.5 metres. The closest drill hole
along-strike to the southwest is located 150 metres away and likely missed the target horizon given the
reported basement geology. Therefore, the mineralized zones are open along-strike to the southwest.
Summer Drilling Plans
A summer core drilling program to follow up on the results in drill holes GG18-08 and GG18-09 is being planned.
Drilling will likely begin in June and will consist of 8-10 holes targeting both areas.
Steve Blower, Vice President of Exploration commented: “The geochemical results from both drill holes GG18-
08 and GG18 -09 are encouraging, and further support our view that the Geiger property remains highly
prospective for the discovery of economic uranium deposits. I’m particularly encouraged by the robustness of
the intersections and the open nature of the mineralization. Our technical team that includes Senior Geologist
Andy Carmichael and Geologist Justin Rodko, has done a terrific job of identifying and prioritizing drill targets
at Geiger and has delivered outstanding follow-up results.”
Craig Parry, Chief Executive Officer commented: “ I’m pleased to see our strategy of building on our portfolio
of exploration properties in the highl y prospective eastern Athabasca Basin is yielding exciting exploration
results. The recent closing of our fund raising puts us in an excellent position to follow up these results with a
summer drill program and we look forward to reporting on this work when it commences.”

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 sta tements 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 wit h 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 fo rward-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 statement s or
