Focused on Lithium Growth
Avalon's new strategy is focused on organic growth of its lithium portfolio, as well as finding strategic growth opportunities in the region. Growth at Separation Rapids will be advanced through drilling and project permitting work.

Planned activities in H2 2023 will comprise of exploration work across all lithium projects including:

• Separation Rapids - continue with deeper drill program to further test the extensions of the deposit.
• Snowbank - previous exploration includes sample assays of up to 2.51% Li2O over 1.1 metres, indicating that petalite comprises approximately 50% of the mineral content in the rock sampled.
• Lilypad - shows lithium samples at greater than 1% Li2O occurring primarily in spodumene in three separate occurrences. Avalon plans to initiate a drill program on select targets at Lilypad.

Development Initiatives
Further baseline test work continues this year to thoroughly understand and de-risk the site in preparation for future development and production activities, with a plan to submit the permitting application in late 2023. In addition, early discussions and a draft study are underway for a powerline to site.

Lithium Conversion Facility
The proposed lithium hydroxide conversion facility is an important part of Avalon's growth strategy. Future activities include:

• finalizing the purchase of an industrial property located in Thunder Bay, Ontario;
• advancing commercial and financing discussions with various parties, the provincial and federal government, and with downstream parties interested in supporting the project; and
• completing test work to demonstrate the conversion of petalite and lepidolite concentrate into a lithium hydroxide product.

Community and Indigenous Engagement
Avalon looks to build upon a foundation of partnership with indigenous communities and seeks to elevate all forms of communication, partnerships and opportunities. Initial work has begun on community engagement and planning sessions with Indigenous groups. The Company's discussions will include participation from various groups and include former six term Chief of the Eabametoong First Nation, Harvey Yesno, who also serves as a director on Avalon's Board.
