ISOENERGY TO COMMENCE WINTER URANIUM DRILLING PROGRAMS AT THORBURN LAKE AND RADIO

IsoEnergy Ltd. has all exploration permits in hand, and winter drill campaigns at each of its Thorburn Lake and Radio uranium projects in the eastern Athabasca basin of Saskatchewan will commence in mid-January.

As reported on Jan. 5, 2017, results of phase 1 drilling at Thorburn Lake included the intersection of uranium mineralization in drill hole TBN16-19 and elevated radioactivity at the unconformity in several other drill holes. The highlight of phase 1 drilling at Radio was the discovery of a large zone of basement clay alteration with a tenor and scale that are typically found close to significant uranium mineralization, including the nearby Roughrider uranium deposit.

Thorburn Lake, located seven kilometres east of the Cigar Lake uranium mine, is 100 per cent owned. IsoEnergy has an exclusive right to earn a 70-per-cent interest in the Radio property, which is located two kilometres east of the Roughrider uranium deposit.

Thorburn Lake drill program

IsoEnergy is planning a 10-hole (4,300 metres) phase 2 winter drilling program to follow up on the 2016 results. The primary target will be the northeast strike extension of the mineralization, alteration and structural zone defined during the first phase of drilling in 2016. Secondary targets include several resistivity low anomalies observed in an 85-line-kilometre DC-resistivity geophysical survey completed in October, 2016.

Radio property drill program

At Radio, IsoEnergy is planning a 10-hole (4,100 metres) phase 2 winter drilling program to follow up on the 2016 results. The primary target will be uranium mineralization associated with the large zone of basement clay alteration identified in the first phase of drilling in 2016.

Craig Parry, president and chief executive officer, commented, "Given the success of our initial drilling in 2016 in delineating mineralization and alteration typically associated with and nearby to uranium deposits such as Rio Tinto's Roughrider, we very much look forward to commencing the winter phase of our drill campaign in coming days."
