DENVER, Sept. 03, 2024 (GLOBE NEWSWIRE) -- American Rare Earths (ASX: ARR | OTCQX: ARRNF | ADR: AMRRY) (“ARR” or the “Company”) is pleased to announce the first assay results from the 2024 drilling campaign at the Cowboy State Mine (“CSM”) area of its wholly owned subsidiary, Wyoming Rare (USA) Inc (“WRI”).

ALS Global provided assay results for 756 samples from 11 core and reverse circulation holes, plus one partial hole. Since drilling concluded final drill hole locations were surveyed and geophysical logs for each drill were collected. Additionally, acoustic televiewer logs were collected in 7 core holes.

Drill hole HC24-RM035 showed an average grade of 4,393 ppm TREO across the entire 299.1m length of the drill hole. The results continue to indicate the deposit remaining open at depth and extending well into Red Mountain. Likewise, drill hole HC24-RM023 has an average TREO grade of 4,006 ppm over 117.5m. WRI geologists prepared and shipped 54 core samples to WSP for geomechanical analysis. WRI also provided WSP with televiewer logs collected during the program.

Chris Gibbs, CEO, commented:
"These first assay results continue to demonstrate the upside potential of the Halleck Creek district. The 2024 drilling indicated elevated rare earth mineralization of the CSM area extending well into Red Mountain. The sheer size and scale of the deposit continues to grow as these results confirm the deposit remaining open from surface to depths of at least 300m.”

Gibbs continued: “These drill holes allow us to expand our resource estimates into Red Mountain in the western portion of the CSM area. Our team continues to focus development on the CSM area, a portion of the Halleck Creek Wyoming State Tenements. With a pathway to State permitting and recent Government funding, the CSM area represents a unique opportunity to work with the State of Wyoming to rapidly advance the Project. When the remaining assay results are received, we will update our geological models and resource estimates. This data, together with the results of geomechanical test work, will provide the basis for detailed mine planning within our upcoming PFS.”

WRI geologists are also using the assay data, and whole rock geochemistry to update lithological designations of specific rock types within the Red Mountain pluton. Geological modelling domains are also being updated based on these rock type designations. Once the remaining assay samples are received from ALS geological models will be updated to reflect all data at the CSM Area.

This announcement is authorized for release by the CEO of American Rare Earths.

FAQ

What were the key drill results from American Rare Earths' 2024 campaign at the Cowboy State Mine?

The key drill results include HC24-RM035 with 299.1m @ 4,393 ppm TREO and HC24-RM023 with 117.5m @ 4,006 ppm TREO. The drilling showed elevated rare earth mineralization from surface to depths of at least 300m.

How will the 2024 drill results impact American Rare Earths' (ARRNF) project development?

The results will be used to update geological models, resource estimates, and provide input for the upcoming Prefeasibility Study (PFS). This data will contribute to detailed mine planning and potentially expand the resource estimates into the Red Mountain area.

What is the significance of the Cowboy State Mine area for American Rare Earths (ARRNF)?

The Cowboy State Mine area represents a unique opportunity for American Rare Earths to rapidly advance the project with Wyoming State support. It has shown potential for a large-scale rare earth deposit with mineralization open at depth and extending into Red Mountain.

When will American Rare Earths (ARRNF) update its resource estimates for the Halleck Creek project?

American Rare Earths will update its geological models and resource estimates once the remaining assay results are received from ALS Global. This updated data will then be incorporated into the upcoming Prefeasibility Study (PFS).
