(TSX:AVL - News; OTCQX:AVARF) ("Avalon" or the "Company") is pleased to announce that it has received a positive report from an independent analysis by Jantzi- Sustainalytics of core stakeholder perceptions, and its Environmental, Social, and Governance ("ESG") performance.In May 2010, Avalon engaged Jantzi-Sustainalytics to assess Avalon's sustainability performance against a number of benchmarks including stakeholders' expectations, competitors' performance, industry average performance levels, and socially responsible investor expectations.The Jantzi-Sustainalytics independent analysis, conducted over a three-month period, included in person and telephone interviews with a diverse range of stakeholders; a review of Avalon's corporate policies, operating and administrative procedures, public disclosures, and a comprehensive questionnaire to management and advisors. Avalon's core stakeholders fall within seven groups: aboriginal/local communities, investors, non-governmental organizations ("NGOs"), government, contractors and advisors, and staff. The assessment also included the comparison of Avalon's management systems and performance against four peer companies, three of which were already known to Jantzi-Sustainalytics, and one other for which the firm conducted an independent assessment based on published information.The results of the comparisons are shown in the table below. The ranking system is based on a score of 0 to 100. As can be seen from the table, Avalon's performance ranks above average among other similar companies with which it was compared.

Simon MacMahon, Director, Jantzi-Sustainalytics Sustainability Intelligence Team, noted, "For an exploration and development company, Avalon demonstrates strengths in a number of important sustainability areas, particularly in aboriginal relations. Avalon has also demonstrated that it embraces the opportunity to further strengthen its sustainability performance as it progresses towards the permitting and production phases by further enhancing its management systems, transparency and public disclosure, including being transparent about the limitations posed by its size and the scope of its projects."Don Bubar, Avalon's President & CEO was pleased with the results. "Avalon is well aware that as it progresses through permitting to production, stakeholder expectations for the sustainable management of material issues will continue to evolve and inevitably become more complex. The Company is prepared to commit the human resources and provide the policy framework, practices and procedures, and transparent reporting necessary to improve its sustainability performance and enhance its current reputation as a socially-responsible, small-cap company. By doing so, we hope to attract the interest of the socially-responsible investment community, as well as clean technology investors interested in commodities" noted Bubar.As Avalon progresses through the permitting and mine development stages, over the next twelve to twenty-four months, the Company will respond to many of Jantzi-Sustainalytics' findings, including actions to:

Annual Sustainability Report and disclosing the risks and opportunities
posed by climate change.
