ISOENERGY EXPANDS LAROCQUE EAST URANIUM PROPERTY THROUGH STAKING

IsoEnergy Ltd. has expanded its 100-per-cent-owned Larocque East property, home to the Hurricane uranium zone. The Hurricane zone is a new discovery of high-grade uranium mineralization located in the prolific eastern Athabasca basin, Saskatchewan.

Through staking on May 28, 2019, the company added a contiguous parcel of mineral claims totalling 4,850 hectares. This increases the total area of the Larocque East property to 8,371 hectares. The newly staked ground encompasses an eight-kilometre-long east-west-oriented magnetic low corridor that includes approximately four km of electromagnetic (EM) conductors known as the Bell North trend. The conductors have been the focus of wide-spaced reconnaissance uranium drilling campaigns as recently as 2014. Results from this drilling include weak uranium mineralization (0.11 per cent triuranium octoxide (U3O8) over 0.5 m) at the unconformity in drill hole BL14-16, located 11 km west of the Hurricane zone. Additionally, the presence of significant sandstone and basement alteration associated with faulted graphitic basement rocks suggests that there is significant discovery potential remaining on the Bell North trend.

Steve Blower, vice-president, exploration, commented: "I'm very pleased that we've added these claims to our Larocque East property at very little cost. Our technical team did a terrific job of evaluating the exploration potential, and then executing a solid staking plan in a competitive situation. The sparse nature of the drilling on the EM conductors, combined with anomalous geochemistry and encouraging geology in the drill holes reminds me of the original Larocque East property when it was acquired in 2018, before the Hurricane zone was discovered."

Craig Parry, chief executive officer, commented, "This acquisition of additional prospective claims contiguous with the Larocque East property is another example of executing our strategy to expand our footprint of high-potential uranium exploration tenure in the eastern Athabasca basin, the infrastructure-rich home of the world's highest-grade uranium mines."

Larocque East

Larocque East now consists of 20 mineral claims totalling 8,371 hectares. The original portion was purchased in May, 2018, before being expanded by the staking reported herein. The property is owned 100 per cent 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 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-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 Cameco Corp.'s neighbouring property to the southwest of Larocque East. The Hurricane zone was discovered in July, 2018, and was recently followed up with a 12-hole drilling campaign in the winter of 2019. Eleven of those 12 drill holes intersected substantial uranium mineralization, including 10.4 per cent U3O8 over 3.5 m in drill hole LE19-02 and 3.2 per cent U3O8 over 8.5 m in drill hole LE19-12. Drilling at Cameco Corp.'s Larocque Lake zone on the neighbouring property to the southwest has returned historical intersections of up to 29.9 per cent 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 Larocque East 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 Larocque East property to date.

Stock option grant

The company has also granted 100,000 incentive stock options to a consultant of the company pursuant to the company's stock option plan. The options were granted on June 5, 2019, are exercisable at a price of 50 cents, and have a term of five years vesting in equal quarterly instalments commencing on the three-month anniversary of the grant date. All options issued are subject to TSX Venture Exchange acceptance.
