Alexco Resource : 2022 Notice & Access Notification to Shareholders

ANNUAL GENERAL MEETING OF SHAREHOLDERS

NOTICE-AND-ACCESS NOTIFICATION TO SHAREHOLDERS

You are receiving this notice as ALEXCO RESOURCE CORP. (the "Corporation" or "Alexco") has chosen to use the notice-and-access model for delivery of meeting materials to its shareholders in respect of its annual general meeting of shareholders to be held on Thursday, June 9, 2022 (the "Meeting"). Under notice-and-access, shareholders still receive a proxy or voting instruction form enabling them to vote at the Meeting. However, instead of receiving a paper copy of the notice of meeting and information circular (the "Circular") for the Meeting (the "Meeting Materials"), shareholders are receiving this notice with information on how to access such Meeting Materials electronically.

MEETING DATE AND LOCATION

WHEN:

Thursday, June 9, 2022 at 1:30 p.m. (Pacific Time)

WHERE:

Suite 1165, 555 Burrard Street, Vancouver, BC

MATTERS TO BE CONSIDERED AND/OR VOTED UPON AT THE MEETING

• 1. To receive and consider the report of the directors and the consolidated financial statements together with the auditors' report thereon for the year ended December 31, 2021;

• 2. To fix the number of directors at six;

• 3. To elect directors for the ensuing year;

• 4. To appoint the auditors for the ensuing year; and

• 5. To consider and, if thought fit, to approve an ordinary resolution approving certain amendments to the Corporation's stock option plan and to approve all unallocated awards under the stock option plan, as more particularly described in the accompanying Circular.

Alexco will not use procedures known as "stratification" in relation to its use of notice-and-access in relation to the Meeting. Stratification occurs when a reporting issuer using notice-and-access provides a paper copy of the relevant Circular to some, but not all, shareholders with the notice package in relation to the relevant meeting.
