III Imperial Metals Corporation

Imperial Metals Corporation (the "Company") (TSX:III) announces that it will conduct a rights offering (the "Rights Offering") to raise gross proceeds of up to approximately C$53,730,456 through the issuance of rights ("Rights") to subscribe for an aggregate of 17,674,492 common shares of the Company ("Common Shares") at a subscription price of C$3.04 per Common Share.

The Rights Offering is being made to all existing shareholders in eligible jurisdictions, as disclosed in the Company's rights offering circular dated May 19, 2022 (the "Rights Offering Circular").

The Company intends to use all of the proceeds from the Rights Offering to pay down its existing credit facility and will make subsequent draw downs to fund capital expenditures at the Red Chris mine and for general working capital purposes. Included within the category “general working capital purposes” are general working capital requirements for all of the Company's business operations, general corporate and administrative activities and exploration activities.

The Rights Offering is being made to the holders of Common Shares of record at the close of business (Pacific Time) on May 31, 2022.

The Company will issue one Right for each outstanding Common Share. Each Right will be exercisable to acquire 0.125 Common Shares of the Company, upon payment of the subscription price per Common Share (called the "Basic Subscription Privilege"). Fractional shares will not be issued and any fractions will be rounded down to the nearest whole number. To illustrate: an eligible holder of 10,000 shares as of the record date would be issued 10,000 Rights, which would entitle the holder to subscribe for 1,250 shares (10,000 x 0.125) for an aggregate price of C$3,800 (1,250 x C$3.04).

The Rights will trade on the Toronto Stock Exchange under the symbol "III.RT.A" commencing on May 31, 2022 and will trade until 9:00 a.m. (Pacific Time) on June 24, 2022. The Rights will expire at 2:00 p.m. (Pacific Time) on June 24, 2022 (the "Expiry Time"), after which time unexercised Rights will be void and of no value. Shareholders who fully exercise their Rights will be entitled to subscribe pro rata for additional Common Shares (the "Additional Common Shares") in the Rights Offering, if available, as a result of unexercised Rights prior to the Expiry Time, subject to certain limitations set out in the Rights Offering Circular (the "Additional Privilege").

A rights offering notice ("Notice") and Rights DRS advice statements ("Rights DRS") will be mailed to each registered shareholder of the Company resident in Canada and certain other eligible jurisdictions as at the record date. Registered shareholders who wish to exercise their Rights must forward the completed Rights DRS, together with the applicable funds, to the Rights agent, Computershare Investor Services Inc., on or before the Expiry Time. Eligible shareholders who own their Common Shares through an intermediary, such as a bank, trust company, securities dealer or broker, will receive materials and instructions from their intermediary.
