Highlights
- Strategic Collaboration with BMO Capital Markets: The engagement of BMO Capital Markets as a financial advisor is a critical milestone in ARR’s strategy to accelerate the development of Halleck Creek by securing strategic investments and partnerships
- High-Grade Drilling Results: The Cowboy State Mine at the Halleck Creek Project yielded some of the highest- grade Total Rare Earth Oxide (TREO) results to date, including:
- 148.0m @ 4,451 ppm TREO (max 6,198 ppm TREO)
- Strategic Facility Secured: ARR’s subsidiary, Wyoming Rare USA Inc., secured a key facility at the Western Research Institute in Wyoming. This facility will centralise operations, house core samples, and serve as the future site for a pilot plant
- $7.1 Million State Grant: ARR received the first reimbursement of over A$450,000 from the Wyoming Energy Authority to support ongoing initiatives
Strategic Engagement
ARR engaged BMO Capital Markets, a global leader in metals and mining financial advisory, to accelerate the development of its Halleck Creek Project in Wyoming. BMO will assist ARR and its U.S. subsidiary, Wyoming Rare USA Inc., in securing strategic investments, partnerships, joint ventures, and offtake agreements to position Halleck Creek as a cornerstone of the U.S. critical minerals supply chain. This move aligns with growing U.S. bipartisan support for onshoring critical minerals and Wyoming’s economic goals. With support from the Wyoming Energy Authority and a Letter of Interest from the U.S. Export-Import Bank, ARR aims to capitalise on favourable market dynamics and establish long-term shareholder value while contributing to the national agenda for a secure, domestic rare earth supply chain.
Drilling Operations
ARR announced on 27 November final assay results from its 2024 drilling campaign at the Cowboy State Mine (CSM) within the Halleck Creek Project, Wyoming. These results highlight some of the highest-grade Total Rare Earth Oxide (TREO) intersections recorded in the region, confirming the project’s potential as a leading North American rare earth resource.
Key Highlights:
- High-Grade Intersections:
- HC24-RM046: 148.0 m @ 4,451 ppm TREO, including 52.5 m @ 5,273 ppm TREO (maximum 6,198 ppm TREO)
- HC24-RM048: 161.5 m @ 4,275 ppm TREO, including 40.5 m @ 5,287 ppm TREO (maximum 5,869 ppm TREO)
- HC24-RM049: 90.0 m @ 4,353 ppm TREO, including 16.5 m @ 5,313 ppm TREO (maximum 6,049 ppm TREO)
Drilling results demonstrate extensive high-grade zones, which will support updated geological models and resource estimates, crucial for advancing the project’s development.
These results emphasise the project’s potential to become a flagship rare earth resource for North America, aligning with the U.S. government’s strategic push to secure domestic critical mineral supply chains for defence and energy transition needs.
2024 Drill Hole Locations and Assay Summaries
With geological maps updated and Odessa Resources Ltd refining resource estimates, ARR announced an updated resource estimate on 29 January 2025 is and progressing a Pre-Feasibility Study (PFS), while engaging with strategic partners to unlock the project’s value.
Facility to Support Halleck Creek Project
Wyoming Rare (USA) Inc. secured a facility at the Western Research Institute in Laramie, Wyoming, marking a major step forward for the Halleck Creek Rare Earths Project. The facility will centralise operations by housing all drill core and assay samples and will also accommodate the construction of a pilot plant to advance rare earth processing capabilities. This partnership with the Western Research Institute, a renowned non-profit organisation specialising in energy systems and materials research, enables collaboration to enhance critical mineral development. The move aligns with Wyoming’s strategic goal of becoming a leader in rare earth element development while supporting the onshoring of critical mineral supply chains for the USA.
Wyoming Grant
The Company has received its first reimbursement of over A$450,000 from the Wyoming Energy Authority (WEA) grant, marking progress in developing the Cowboy State Mine at Halleck Creek. Part of a larger A$10.7 million (US$7.1 million) grant awarded in June 2024, the funds will support exploration drilling, environmental studies, and prefeasibility assessments, helping de-risk the project and achieve the Company’s 2025 goals. This milestone underscores ARR’s commitment to advancing the project and collaborating with the WEA to support Wyoming's energy strategy.
