IsoEnergy Acquires Collins Bay Extension Uranium Property

VANCOUVER, Oct. 16, 2019 - IsoEnergy Ltd. ("IsoEnergy" or the "Company") (TSXV: ISO; OTCQX: ISENF) is pleased to report that it has added two new uranium exploration properties, Collins Bay Extension and Edge, to its portfolio of properties in the eastern Athabasca basin of Saskatchewan (Figure 1). The highlight is the Collins Bay Extension property located along-trend of, and within seven km of, the Eagle Point - Collins Bay - Rabbit Lake (Rabbit Lake) uranium mine and mill complex. Both Collins Bay Extension and Edge are 100% owned by IsoEnergy.

Steve Blower, Vice President of Exploration commented: "Good uranium exploration ground in the Athabasca basin is still tightly held and difficult to acquire. In that context I'm extremely pleased with the results of our recent staking efforts – especially with respect to the Collins Bay Extension claims. Encompassing long lengths of two fertile uranium trends - Collins Bay and Tent-Seal, the potential for discovery of basement hosted mineralization on this property is high."

Craig Parry, CEO commented: "The acquisition of these two properties fits well with our strategy of increasing our footprint of high-potential uranium exploration ground in the eastern Athabasca basin. Staking this 100% owned ground against several other exploration companies in a competitive process was a terrific outcome – all at a very low acquisition cost."

Collins Bay Extension Property

The 8,580ha Collins Bay Extension property is located along the inferred northeastern extension of the Collins Bay trend, less than seven km northeast of Rabbit Lake (Figure 2). Currently under care and maintenance since 2016, Rabbit Lake has produced over 200 million pounds of uranium concentrates since 1975, much of which was from basement hosted mineralization at the Eagle Point deposits. The Eagle point deposits are characterized by their remarkable depth extent to at least 900m below the sub-Athabasca unconformity.

In addition to the prolific Collins Bay trend, the Collins Bay Extension property also covers the extension of another fertile conductive trend – Tent-Seal, host to the Tamarack uranium deposit on Cameco Corp.'s Dawn Lake property, and several occurrences of basement hosted uranium mineralization on Orano Canada's McClean Lake property and UEX's Hidden Bay property. The two trends merge on the Collins Bay Extension property in a complicated zone of conductors that suggests a high degree of structural complexity – a perfect setting for basement hosted uranium mineralization. The total strike length of conductive stratigraphy related to the two trends on the Collins Bay Extension property is over 16km.

Located just beyond the edge of the Athabasca sandstone, the Collins Bay Extension property is underlain solely by basement rocks (mostly prospective metasediments of the basal Wollaston group) and there is no sandstone cover. Despite the presence of two prospective trends, there are very few historical core drill holes on the property according to the Saskatchewan government database.

Edge Property

The 4,218ha Edge property is located nine km northeast of the Company's Larocque East property (Figure 3). It covers a large area characterized by low magnetic susceptibility caused by prospective Wollaston group metasedimentary basement rocks beneath a thin cover of Athabasca sandstone. The property is very close to the basin edge, with only 40m of Athabasca sandstone recorded in the only historical drill hole completed on the property. That drill hole intersected 10m of semi-massive and massive pyrite mineralization in the basement rocks.

Next Steps

Compilation of historical data is ongoing for both new properties. Upon completion of this work, exploration programs that may include surficial geochemistry, ground geophysics and ultimately core drilling will be planned. Fieldwork may start in 2020.
