ALEXCO FILES PRELIMINARY SHELF PROSPECTUS AND REGISTRATION STATEMENT TO RENEW EXISTING SHELF PROSPECTUS

Alexco Resource Corp. has filed a preliminary short form base shelf prospectus with the securities commissions in each of the provinces of British Columbia, Alberta, Saskatchewan, Manitoba and Ontario, and a corresponding amendment to its registration statement on Form F-10 (registration statement) with the U.S. Securities and Exchange Commission (SEC) under the U.S./Canada Multijurisdictional Disclosure System to replace the company's short form base shelf prospectus dated July 29, 2016, which will cease to be effective as of Aug. 29, 2018.

The shelf prospectus filings, when final, will allow Alexco Resource to make offerings of common shares, warrants, subscription receipts and/or units up to an aggregate total of $50-million during the 25-month period that the final short form base shelf prospectus remains effective. Such securities may be offered in amounts, at prices and on terms to be determined based on market conditions at the time of sale, and set forth in one or more shelf prospectus supplement(s) and, subject to applicable regulations, may include at-the-market transactions, private placements, public offerings or strategic investments. Information regarding the use of proceeds from a sale of such securities will be included in the applicable prospectus supplement.

The registration statement has been filed with the SEC, but has not yet become effective. Securities may not be sold (nor may offers to buy be accepted) prior to the time the registration statement becomes effective. After the registration statement becomes effective, a copy of the registration statement and a copy of the preliminary short form base shelf prospectus, as well as copies of the final short form base shelf prospectus and any shelf prospectus supplements that may be filed in the future, can be found on SEDAR and on EDGAR, or may be obtained by request to the corporate secretary of Alexco Resource at Suite 1225, Two Bentall Centre, 555 Burrard St., Box 216, Vancouver, B.C., V7X 1M9 (604-633-4888 by phone).

If any securities are offered under the prospectus or registration statement, the terms of any such securities and the intended use of the net proceeds resulting from such offering would be established at the time of any offering, and would be described in a prospectus supplement filed with the applicable Canadian securities regulatory authorities and the SEC at the time of such an offering, and would be made available by Alexco Resource at the above address.
