Lake Superior Lithium has completed its geotechnical program on site, marking another important step forward for the project. Over approximately two weeks, the team completed a 23-hole program to gather critical information about site conditions. The results from the testing and analysis will provide valuable information to support the completion of foundation designs for the buildings and equipment planned as part of the project. This work supports the continued advancement of the Lake Superior Lithium project as we move through the next stages of engineering and development.

Magmic Rare Earths was inspired by the geological processes that formed Avalon's Nechalacho Basal Project more than two billion years ago. As magma cooled and crystallized within the Blatchford Lake Igneous Complex, rare earth elements became concentrated, creating one of North America's most significant rare earth deposits. What makes Nechalacho's Basal Zone especially unique is its economically significant combination of both light and heavy rare earth elements that begin below the 150m mark. This is a relatively uncommon characteristic among rare earth deposits that enhances its strategic importance to North America's critical minerals supply chain. The Northwest Territories is home to the Nechalacho Basal Zone, and its outline in our logo symbolizes the Canadian roots of this strategically important critical minerals resource. Grounded in geology. Proudly Canadian. Building the future of critical minerals.

Avalon Advanced Materials announced that shareholders have approved the Company's proposed share consolidation. The consolidation is intended to support Avalon's broader capital markets strategy as the Company continues advancing its critical minerals projects. Read the full news release: hubs.ly/Q04nv23R0
