Avalon Advanced Materials Inc. (OTCQB: AVLNF) (TSX: AVL) is a Canadian critical minerals developer advancing two high-priority assets: the Nechalacho Rare Earth Elements and Zirconium Project in Canada's Northwest Territories, one of the few non-Chinese deposits containing both light and heavy rare earths, and the Lake Superior Lithium (LSLi) project, a proposed battery-grade lithium hydroxide refinery in Thunder Bay, Ontario. Water Tower Research analyst Dmitry Silversteyn initiated coverage of Avalon Advanced Materials Inc. (OTCQB: AVLNF) on April 7, 2026, framing the stock as one of the most extreme valuation dislocations in the critical minerals space. With combined project net present values of approximately $4 billion across both assets, Avalon Advanced Materials Inc. (OTCQB: AVLNF) trades at roughly 1% of that figure, versus 10–80% for more advanced peers. Silversteyn argues the discount reflects project maturity and study recency, not asset quality, and that each completed milestone, updated economic study, government funding award, or strategic partnership, represents a discrete re-rating event. The most immediate catalyst is the April 2, 2026 reorganization of the Separation Rapids joint venture, which left Avalon Advanced Materials Inc. (OTCQB: AVLNF) debt-free and eliminated an estimated 15% in potential shareholder dilution.

What the Company Does
Avalon Advanced Materials Inc. (OTCQB: AVLNF), founded in 1991 and headquartered in Toronto, is pursuing vertical integration of North American critical minerals supply chains across two fronts. The Nechalacho project, located approximately 100 kilometers southeast of Yellowknife, holds measured and indicated resources of 121.26 million tons with a grading of 1.50% total rare earth oxides (TREO). Its deeper Basal Zone is geologically differentiated, with heavy rare earth content rising from roughly 6% near surface to more than 30% at depth, making it one of the few hard-rock deposits globally with meaningful dysprosium and terbium exposure alongside neodymium and praseodymium.

The LSLi project targets the midstream processing step that most Western lithium developers skip entirely: chemical conversion of spodumene concentrate into battery-grade lithium hydroxide monohydrate. The 2024 Preliminary Economic Assessment (PEA) outlined a 30,000-ton-per-year facility with a C$4.1 billion after-tax NPV at an 8% discount rate, a 48% IRR, and a 2.5-year payback on initial capital expenditures of C$1.2 billion. The project sits on a brownfield industrial site with existing rail, road, and deep-water port access, and uses Metso's alkaline pressure leach technology, which eliminates conventional sulfuric acid roasting and offers up to 60% lower water use versus standard lithium conversion processes.
The Market Backdrop
The geopolitical case for Avalon Advanced Materials Inc. (OTCQB: AVLNF) has sharpened considerably. In April 2025, China imposed export controls on seven heavy rare earth elements, including dysprosium and terbium, along with all related compounds, metals, and magnets. The IEA reports that China controls approximately 91% of global rare earth separation and refining capacity, and 94% of NdFeB permanent magnet production. The Silverado Policy Accelerator found that China's exports of controlled rare earth compounds and metals to the United States were near zero in January and February 2026. As the Global Policy Watch has noted, China produces an estimated 98% of the world's dysprosium and 99% of its yttrium, making domestically sourced heavy rare earths a national security concern, not just a commercial opportunity.

Both the Canadian and US governments have responded. Canada designated rare earths as one of six priority minerals under its Critical Minerals Strategy, and the US Department of Energy announced a $134 million funding opportunity in December 2025 for domestic rare earth recovery and refining. On lithium, the IEA reported that global lithium demand rose nearly 30% in 2024, with the energy sector driving 85% of demand growth across battery metals, while Chinese companies retain more than two-thirds of global lithium processing capacity.
The Competitive Edge
Nechalacho's differentiation from most Western rare earth projects comes down to HREE content. Most deposits in Canada, Australia, and the United States are carbonatite-hosted systems dominated by low-value lanthanum and cerium. Nechalacho's 2013 DFS indicated that heavy rare earths and key magnet elements combined generated more than 82% of separated rare earth oxide revenue, with lanthanum and cerium contributing less than 5%. The deposit also carries zirconium, niobium, and tantalum, adding revenue diversification most pure-play rare earth projects lack.

For LSLi, the edge is the Metso alkaline pressure leach process. In 2025, Avalon Advanced Materials Inc. (OTCQB: AVLNF) announced successful bench-scale production of both lithium hydroxide and analcime using the technology, validating the core chemistry. The analcime by-product has potential commercial applications in construction and industrial markets, adding a revenue stream absent from conventional lithium conversion plants.
Recent Developments and Financial Position
Avalon Advanced Materials Inc. (OTCQB: AVLNF) has executed a deliberate build-out of its technical team since January 2026. The company commissioned an updated PEA for Nechalacho, led by Wood Canada Limited, and launched the LSLi feasibility study engineering process with Nordmin Engineering as lead consultant. In March 2026, the company re-engaged Dave Marsh, who led metallurgical development on the original 2013 Nechalacho DFS, appointed Glen Smith, P.Eng., as Project Director for LSLi Refinery Feasibility and Construction, and named Burl Joseph as Project Director for Nechalacho. SCP Resource Finance was engaged in February as strategic capital advisor for both projects.
The most material recent development came on April 2, 2026, when Avalon Advanced Materials Inc. (OTCQB: AVLNF) completed the reorganization of the Separation Rapids joint venture with SCR-Sibelco NV. Avalon Advanced Materials Inc. (OTCQB: AVLNF) exited its 40% interest in Separation Rapids Ltd. and recovered 100% ownership of the Lilypad cesium project, while eliminating approximately $7.5 million in debt and accrued interest in a non-cash transaction. The company is now debt-free, with an estimated 15% overhang of potential shareholder dilution removed. Shares gained 28.57% on the day of the announcement. As of the most recent quarter, current assets stood at approximately C$16 million against current liabilities of approximately C$9.8 million, providing near-term operational runway ahead of larger financing events.
How the Analyst Sets the Valuation Case
Silversteyn's framework centers on NAV multiples rather than a specific price target, consistent with Water Tower Research's publishing model. On the rare earth side, peer comparisons are instructive. Arafura Rare Earths, with a completed DFS and active financing discussions, trades at approximately 60–80% of its NPV. Rare Element Resources, which secured a US Export-Import Bank letter of interest for up to approximately $553 million in project financing in March 2025, trades near 80–100% of its NPV. Avalon Advanced Materials Inc. (OTCQB: AVLNF) by contrast trades at approximately 4% of the NPV implied by the Nechalacho DFS alone. On the lithium side, early-stage processing-focused developers trade at similarly deep discounts to NPV, reflecting pre-construction risk across the sector. Silversteyn's conclusion is that valuation could progress from roughly 1% of combined NAV today toward 10–25% at a DFS-equivalent stage and 30–60% or higher at financing readiness, with each completed milestone acting as a discrete re-rating trigger.
Risks
Avalon Advanced Materials Inc. (OTCQB: AVLNF) is a pre-revenue, pre-construction developer. Both projects require multi-billion-dollar capital expenditures well in excess of the company's current market capitalization, and the LSLi project depends on securing third-party spodumene feedstock rather than an owned upstream resource. The 2013 Nechalacho DFS is outdated, and Nechalacho still requires a socio-economic agreement with the Government of the Northwest Territories before construction can proceed. Delays in any of financing, updated studies, feedstock agreements, or permitting could extend the development timeline materially.
The Investment Case
Avalon Advanced Materials Inc. (OTCQB: AVLNF) offers exposure to two of the most policy-supported critical minerals themes in the market, rare earth supply chain independence and domestic lithium processing capacity, through a dual-asset platform trading at a fraction of its independently assessed value. The debt elimination, the parallel study processes now underway at both Nechalacho and LSLi, the new project directors, and the engagement of a strategic capital advisor are all consistent with a company moving deliberately from conceptual developer toward feasibility-stage operator. The valuation gap is wide, the assets are real, and the policy environment has rarely been more favorable. For investors with the appropriate time horizon and risk tolerance, the current entry point reflects a development-stage discount, not a judgment on the underlying resource.
