Avalon Ranked in Corporate Knights' “Future 40 Responsible Corporate Leaders in Canada“ for Third Time

Don Bubar, Avalon's President and CEO, commented, "This is well-earned recognition for everyone at Avalon and the sustainability culture we have developed. We believe that making environmental and social responsibility a priority enhances shareholder value by reducing risk while enhancing business opportunities for our Indigenous partners."

Avalon is fully committed to integrating sustainable practices into its business model by minimizing environmental impacts and land disturbed. At the East Kemptville Tin-Indium Project in Nova Scotia, Avalon's current development model will fully remediate the historical environmental liability at site; create no new disturbance area; and minimize GHG production, while profitably recovering tin from low grade stockpiles and other waste materials left on the site.

At the Separation Rapids Lithium Project near Kenora, Ontario, the Company's staged development approach allows for minimizing the environmental footprint of the project while maximizing the number of potential mineral products from the lithium pegmatite, reducing the amount of waste material generated. Under Avalon's current development model, as little as 10% of the mined ore would end up as waste, compared to 90% plus at typical base and precious metals operations.

Avalon is a leader among junior mineral development companies in adopting best practices to reduce its environmental footprint, protect water resources and engage with local communities. The Company has reported annually on its sustainability performance since 2011. Avalon's sixth and current Sustainability Report's theme is Concentrating on Cleantech Materials Production: a theme chosen to reflect the Company's focus on defining profitable business opportunities in the technology metals sector. Avalon's 2017 Sustainability Report can be found online at: http://www.avalonadvancedmaterials.com/_resources/sustainability/AVL-2017-sustainability-report.pdf.

This is the third time Avalon has been ranked as a Future 40 Responsible Corporate Leader in the last four years. This year, Avalon is listed among top-ranking companies such as London Hydro, Vancouver Fraser Port Authority and Dundee Precious Metals.
