8-K: Rare Element Resources Announces Updated Mineral Resource for Bear Lodge Project, Focusing on Key Magnet Materials

Rare Element Resources Ltd. has announced an updated mineral resource estimate for its Bear Lodge Project, emphasizing the recovery of key magnet materials like neodymium and praseodymium.

Summary

• Rare Element Resources Ltd. has completed a new mineral resource estimate for the Bull Hill deposit at its Bear Lodge Project in Wyoming.
• The estimate focuses on maximizing the recovery of key magnet materials such as neodymium, praseodymium, terbium, and dysprosium, as well as lanthanum.
• The mineral resource was estimated using data from 252 core holes drilled between 2009 and 2013, totaling 186,712.5 feet of drilling.
• The estimate also incorporates recovery data from the 2021 pilot plant testing of the company's proprietary technology.
• The mineral resource estimate uses a cut-off grade of 2.18% total rare earth oxide (TREO) and focuses on the oxide and oxide-carbonate zones.
• The measured and indicated resources total 6.02 million metric tonnes at 4.08% TREO, containing 245,500 metric tonnes of TREO and 49,700 metric tonnes of recovered NdPr.
• The inferred resource is 1.90 million metric tonnes at 3.61% TREO, containing 68,500 metric tonnes of TREO and 14,400 metric tonnes of recovered NdPr.
• The estimated overall NdPr process recovery is 90%.

Sentiment

Score: 7

Explanation: The document is positive due to the updated resource estimate and focus on key magnet materials, but it also acknowledges the risks and uncertainties associated with the project. The sentiment is cautiously optimistic.

Positives

• The updated resource estimate focuses on key magnet materials, aligning with growing demand in defense and green technologies.
• The company's proprietary technology allows for a focus on a higher grade and smaller pit design.
• The company is preparing a Technical Report Summary (TRS) and an updated NI 43-101 compliant technical report.
• The company has a long-term upside potential in the Carbon, Whitetail, and Taylor deposits.

Negatives

• Mineral resources do not have demonstrated economic viability.
• There is no guarantee that any part of the mineral resource will be converted to mineral reserves in the future.
• Inferred mineral resources have a high degree of geological uncertainty and cannot be included in mineral reserves.
• There is no certainty that the inferred mineral resources will be converted to measured and indicated mineral resource categories.

Risks

• The company's ability to raise sufficient capital to fund the operation of the demonstration plant is a risk.
• The prevailing market conditions for rare earth products and mining industry cost inputs are a risk.
• Changes in interpretations of geological, metallurgical, mining or processing information are a risk.
• Environmental and regulatory risks are a risk.
• The availability of sufficient capital for the future development and operations of the company is a risk.

Future Outlook

The company expects demand for magnet materials to grow exponentially over the next 30 years and believes this strategy provides the greatest opportunity for the company to capitalize on the projected rare earth demand growth.

Management Comments

• With demand for magnet materials expected to grow exponentially over the next 30 years, driven primarily by their use in defense and green technologies, it makes sense to focus our efforts on those key magnet materials in this resource model.
• This will ensure that over the longer term, we are aligned with the national security interests and decarbonization goals of the United States.
• Our proprietary rare earth recovery and separation technology enabled us to look at the body of geological data we have generated through a different lens.
• That work allows us to focus on a higher grade and smaller pit design.
• I believe this strategy provides the greatest opportunity for the Company to capitalize on the projected rare earth demand growth and most clearly aligns with our innovative technology while allowing us to preserve the long-term, upside potential of the Bear Lodge Project.

Industry Context

The announcement comes amid growing global demand for rare earth elements, particularly those used in high-strength permanent magnets, which are critical for defense and green technologies. The focus on key magnet materials aligns with national security and decarbonization goals.

Comparison to Industry Standards

• The mineral resource estimate is reported in accordance with Regulation S-K (CFR Title 17 Part 229 Items 1300-1305), which is a standard for US public companies.
• The company is also preparing an updated technical report compliant with Canadian National Instrument NI 43-101, which is a standard for Canadian public companies.
• The use of a 2.18% TREO cut-off grade is a common practice in the industry for reporting mineral resources.
• The company's focus on key magnet materials such as neodymium and praseodymium is aligned with the current market demand and strategic importance of these elements.
• The company's use of a proprietary recovery and separation technology is an innovative approach that could provide a competitive advantage.

Stakeholder Impact

• Shareholders will be informed of the updated mineral resource estimate and the company's focus on key magnet materials.
• The company's focus on domestic supply of rare earth elements aligns with the national security interests of the United States.
• The company's focus on green technologies aligns with the decarbonization goals of the United States.

Next Steps

• The company is preparing a Technical Report Summary (TRS) in accordance with Regulation S-K.
• The company is also preparing an updated technical report compliant with Canadian National Instrument NI 43-101.
• The company will continue to advance the Bear Lodge REE Project.
