Alexco Resource Corp.

Alexco owns the Keno Hill Silver District in Canada's Yukon Territory, historically one of the highest grade silver districts in the world, producing more than 200 million ounces of silver at an average grade of approximately 1,250 grams per tonne ("g/t") silver. Alexco commenced commercial production in the Keno Hill Silver District in 2011, producing approximately two million ounces of silver and more than 20 million pounds of lead and zinc concentrate per year into 2013 when production was suspended in the face of collapsing silver and base metal prices. Since then, Alexco has made two significant exploration discoveries and renegotiated a number of third party agreements. The Flame & Moth and Bermingham deposit discoveries have added more than 20 million ounces of silver at an average grade of 800 g/t silver to Alexco's indicated resource base in the district. These additions have led to a new and expanded multi-mine production plan reflecting significantly increased resources, a longer life and reduced all-in sustaining costs. In 2017 Alexco is focused on moving the district back to an operations start-up in the second half of 2018 by initially executing an advanced underground exploration program at its Bermingham deposit, followed by underground development of the Flame & Moth deposit along with recommissioning of all surface plant and infrastructure. In addition, in 2017 Alexco will continue with surface exploration programs in proximity to existing resources in anticipation of adding to a growing resource base. Employing a unique business model, Alexco also provides mine-related environmental services, remediation technologies and reclamation and mine closure services to both government and industry clients through the Alexco Environmental Group, its wholly-owned environmental services division.
