Premier Gold Mines Ltd. Announces Closing of C$80.4 Million Financing by its Subsidiary, i-80 Gold Corp.

THUNDER BAY, March 18, 2021 - Premier Gold Mines Ltd. ("Premier" or the "Corporation") (TSX: PG) (OTCPK: PIRGF) is pleased to announce that its wholly-owned subsidiary, i-80 Gold Corp. ("i-80") has closed its previously announced private placement offering of 30,914,614 subscription receipts of i-80 (the "Subscription Receipts") at a subscription price of $2.60 per Subscription Receipt for aggregate gross proceeds of approximately C$80.4 million (the "Offering"). The Offering was conducted on a marketed private placement basis through a syndicate of agents led by CIBC World Markets Inc. ("CIBC"), and including Sprott Capital Partners LP, Stifel Nicolaus Canada Inc., Canaccord Genuity Corp., Scotia Capital Inc., BMO Nesbitt Burns Inc., Cormark Securities Inc. and RBC Dominion Securities Inc. (collectively, the "Agents").

Each Subscription Receipt will be automatically exchanged, without any further consideration or action by the holder thereof, for one common share in the capital of i-80 (the "Common Shares") and one quarter of one common share purchase warrant (each whole warrant, a "Warrant") upon the satisfaction of the Escrow Release Conditions (defined herein). Each whole Warrant will entitle the holder thereof to acquire one Common Share at a price equal to the greater of (i) C$3.64, and (ii) the volume-weighted average trading price of the Common Shares on the Toronto Stock Exchange (the "TSX") for the first five days of trading, until September 18, 2022.

The gross proceeds of the Offering, less (i) 50% of the commission payable to the Agents and the Agents' expenses of the Offering and (ii) the C$24.1 million subscription by Equinox Gold Corp. ("Equinox"), which will be set off against the principal amount outstanding under the Loan (defined herein), have been deposited in escrow with the TSX Trust Company (the "Subscription Receipt Agent") and will be released to i-80 upon the satisfaction of certain conditions, including: (i) the completion of the Corporation's plan of arrangement (the "Arrangement") pursuant to an arrangement agreement among the Corporation, i-80 and Equinox dated December 16, 2020 (the "Arrangement Agreement"); (ii) the Common Shares (including the Common Shares issuable upon exercise of the Warrants) having been conditionally approved for listing on the TSX; and (iii) certain other customary conditions (collectively, the "Escrow Release Conditions"). In the event that the Escrow Release Conditions are not satisfied on or prior to July 16, 2021 or such later date as the Corporation and CIBC may mutually agree upon in writing, the proceeds of the Offering will be returned to the holders of the Subscription Receipts and the Subscription Receipts shall be cancelled.

The proceeds of the Offering are expected to be used by i-80 for working capital and general corporate purposes, to pay for exploration and development expenses related to i-80's mining projects, and to fund the cash portion of the purchase price for the acquisition of the Getchell project in Nevada (the "Getchell Project") from affiliates of Waterton Global Resource Management, Inc. ("Waterton").

"Upon closing of this financing, i-80 will have the balance sheet to execute on its business strategy" stated Ewan Downie, President and CEO of Premier. "We will be well positioned to rapidly advance this Company immediately upon listing."

The Subscription Receipts issued pursuant to the Offering will be subject to a four-month hold period; provided, however, that, subject to the completion of the Arrangement (i) the Common Shares issuable upon the conversion of the Subscription Receipts will be freely tradeable on the TSX and not subject to any statutory hold period, and (ii) the Warrants issuable upon the conversion of the Subscription Receipts will not be subject to any statutory hold period.

The Subscription Receipts were offered by way of marketed private placement to "accredited investors" in all provinces and territories of Canada and by way of private placement in the United States to "accredited investors" and "qualified institutional buyers" pursuant to Regulation D or Section 4(a)(2) of the U.S. Securities Act of 1933 (the "1933 Act") and internationally pursuant to applicable private placement exemptions.

Concurrently with the closing of the Offering, Equinox has advanced to i-80 a US$20.75 million bridge loan (the "Loan") that will be used by i-80 for the purposes of making a US$20.75 million cash deposit with affiliates of Waterton in partial satisfaction of the purchase price payable to Waterton for the acquisition of the Getchell Project. The Loan matures 10 banking days following the closing of the Arrangement (or, if earlier, when the Loan is otherwise terminated in accordance with its terms) (the "Maturity Date"), and bears interest at a rate of 5% per annum that will be payable in arrears on the Maturity Date. The Loan is secured against the assets of i-80, Premier and Premier Gold Mines USA, Inc., and subordinated to the security of existing secured creditors. Equinox's subscription price payable under the Offering for 9,274,384 Subscription Receipts for gross proceeds of approximately C$24.1 million will, upon the filing of the Articles of Arrangement in respect of the Arrangement, be set-off against a corresponding amount of the principal amount outstanding under the Loan, and has not been deposited with the Escrow Agent under the Offering.
