Avalon Initiates Updated Preliminary Economic Assessment for Nechalacho Project

On January 15, 2026, Avalon Advanced Materials Inc. announced it has commissioned Wood Canada Limited to conduct an updated Preliminary Economic Assessment (PEA) for its Nechalacho Rare Earths and Zirconium Project in the Northwest Territories. This study aims to refresh a 2013 Definitive Feasibility Study (DFS) by incorporating modern processing technologies—specifically the "Hybrid Supercritical Refining" (HSR) process previously tested with Engina Corp—and current cost assumptions. The PEA is expected to take approximately six months, with a transition to a new DFS planned immediately thereafter.

This news is a logical, albeit delayed, step in rehabilitating the Nechalacho asset. The project has been largely stagnant since the 2013 DFS due to unfavorable market conditions and high costs. - Positive: Refreshing the economics with a potential 90% recovery rate (from the Nov 2024 Engina news) could significantly improve the project's Net Present Value (NPV). It signals to the market that Nechalacho is no longer just a "legacy" asset but a core pillar alongside the lithium strategy. - Neutral/Negative: A PEA is a step backward in the "feasibility" ladder compared to the 2013 DFS. While costs and tech must be updated, it highlights that the project is at least 12-18 months away from a construction decision, even in a best-case scenario. - Resource Context: The project contains high concentrations of magnet-grade materials, but the wildfire in Sep 2025 near Thor Lake remains a reminder of the operational risks in remote northern jurisdictions.

Avalon is a Canadian mineral developer transitioning from a pure explorer to a mid-stream processor. - Flagship 1 (Lithium): The Thunder Bay Lithium Refinery (Lake Superior Lithium Inc.). Goal: 30,000 tpa lithium hydroxide. PEA 2024 suggests an NPV of C$4.1B, but requires C$1.3B in Capex. - Flagship 2 (REE): Nechalacho Project (NWT). One of the few deposits with both light and heavy REEs.
