("AEG"), has acquired Contango Strategies Ltd. ("Contango"), a private company based in Saskatoon, Saskatchewan, for consideration of $1,388,000 comprising $971,600 in cash and 237,999 common shares of Alexco at a deemed value of $416,400.

Contango specializes in biological (passive, semi-passive and active) water treatment systems for mining, oil and gas, and industrial operations. Contango operates a year-round environmentally controlled pilot-scale facility, which allows for the development, testing and optimization of technologies such as bioreactors and constructed treatment wetlands. Additionally, genetic profiling using Contango's in-house DNA sequencing facility and microbiology laboratories can detect and identify microbes for applications including bioreactor optimization, corrosion and fouling correction, and environmental remediation.

Jim Harrington, President of AEG commented, "With the addition of Contango's advanced technology and research facilities it will enable AEG to continue to be leaders in the sector and at the forefront of applied environmental science, especially in mining related industrial applications. The Contango team will not only expand our capacity and bring with it a strong client base but it will enable AEG to provide a much broader and diversified service to the industry."

Clynt Nauman, CEO and Chairman of Alexco added, "We are very pleased to welcome Dr. Simair, Dr. Friesen and the rest of the Contango team to Alexco and look forward to them being important contributors to the overall growth of AEG. This compelling transaction delivers immediate value to shareholders with annual revenue expected to be in excess of $2.5 million but more importantly, I believe this type of science and technology is the future of environmental remediation and provides AEG with important additional tools to tackle complex environmental issues for our many clients. This transaction is the next step in growing our environmental business and should be viewed as our commitment to see AEG reach its full potential."

Monique Simair, President and Founder of Contango commented, "We are excited to join the Alexco team and look forward to expanding the range of services offered to our clients. This transaction enables us to contribute Contango's unique technologies and services to a broader client base and provides, under one banner, a full breadth of water treatment capabilities. Our laboratories and pilot-scale testing facilities will complement AEG's expertise in the construction and operation of water treatment systems and turn-key environmental site management and remediation."
