/NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR DISEMMINATION IN THE UNITED STATES/

VANCOUVER, July 23, 2020 - IsoEnergy Ltd. ("IsoEnergy" or the "Company") (TSXV: ISO) (OTCQX: ISENF) is pleased to announce that it has agreed to terms with Queen's Road Capital Investment Ltd. ("QRC") (TSXV: QRC) for a US$6 million private placement of unsecured convertible debentures (the "Debentures"). The Debentures will be convertible at the holder's option at a conversion price of C$0.88 into approximately 9.1 million common shares of the Company (the approximate number of common shares to be issued is based on current exchange rates, with the actual number of common shares to be issued dependent on the exchange rate at the time of conversion).

Concurrent with the proposed Debenture offering, the Company also announces a non-brokered private placement for gross proceeds of up to C$4 million (the "Private Placement"). Pursuant to the terms of the Private Placement, the Company will issue up to 5,882,352 common shares at a price of C$0.68 per share (the "Private Placement Price"). NexGen Energy Ltd. ("NexGen") (TSX: NXE), the Company's majority shareholder, has agreed to subscribe for C$3 million of the Private Placement.

Craig Parry, Chief Executive Officer of IsoEnergy, commented: "It is with great pleasure that we welcome QRC as a strategic investor of IsoEnergy. Warren Gilman and his team at QRC have a long track record of success in the natural resource sector, specifically in uranium, and this investment is a tremendous show of support as we enter the next phase of exploration at Hurricane. Alongside QRC, we are thrilled that our major shareholder, NexGen, has continued to demonstrate its support of IsoEnergy and its confidence in our strategic approach. Following the completion of these financings, IsoEnergy will have nearly C$15 million in the treasury and see us fully-funded through the next stage of exploration and resource delineation at Hurricane."

Terms of the Debentures

The Debentures will carry an 8.5% coupon (the "Interest") over a 5-year term and will be convertible at the holder's option into common shares of the Company at a conversion price of C$0.88 (the "Conversion Price"), which is equal to a 30% premium to the Private Placement Price.

The Company will be entitled, on or after the third anniversary of the date of issuance of the Debentures, at any time the 20-day VWAP on the TSX Venture Exchange (the "TSXV") exceeds 130% of the Conversion Price, to redeem the Debentures at par plus accrued and unpaid Interest.

The Interest is payable semi-annually with 6% payable in cash and 2.5% payable in common shares of the Company, subject to TSXV approval, at a price equal to the market price of the Company's common shares on the TSXV on the day prior to the date such Interest is due.

The Interest can be reduced to 7.5% per annum on the public dissemination by the Company of an economically positive preliminary economic assessment study, at which point the cash component of the Interest will be reduced to 5% per annum.

General

The gross proceeds of the Debentures and the Private Placement will be used for exploration of the Company's Athabasca Basin projects and general working capital purposes. All securities issued under the Private Placement will be subject to a statutory hold period in Canada expiring four months and one day from the date of issuance. The closing of the Private Placement and Debentures is expected to occur on or around August 17, 2020 and is subject to certain conditions including, but not limited to, the receipt of all necessary regulatory approvals, including the acceptance of the TSXV.

The Company anticipates that Insiders of the Company, in addition to NexGen, will subscribe for common shares in the Private Placement. The issuance of common shares to Insiders is considered a related party transaction subject to Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions. The Company intends to rely on exemptions from the formal valuation and minority shareholder approval requirements provided under sections 5.5(a) and 5.7(a) of Multilateral Instrument 61-101 on the basis that the participation in the private placement by the Insiders will not exceed 25% of the fair market value of the Company's market capitalization. A material change report in connection with the Private Placement will be filed less than 21 days before the closing of the Private Placement. This shorter period is reasonable and necessary in the circumstances as the Company wishes to complete the Private Placement in a timely manner.
