American Rare Earths (ASX: ARR) has obtained highly promising assay results from 332 samples taken from four core holes at the Southwest project area within its flagship La Paz project in Arizona, USA.
The company drilled 821 m and collected 677 samples from nine holes during February to April 2022. This first set of assay results announced here are from four core holes drilled during this programme and demonstrate rock type associated with rare earth grades as well as two drill holes showing extensive rare earth enrichment over lengths exceeding 50 meters. The company is now looking forward to the remaining results.
MD and CEO Chris Gibbs said the results support the development of the US domestic rare earths supply chain and highlights the strategic value of our assets to the US Government as it identifies risks in the supply chain for critical minerals including rare earth elements.
The company is accelerating activities to expand JORC resources at La Paz, as it targets 742 – 928 million tonnes (MT) of rare earths mineralised rocks to add to the 170MT La Paz resource.
“We are very excited by these results received from the drill programme at the La Paz Southwest zone,” Mr Gibbs said.
“They confirm our exploration targets and reinforce our strong view that the zone has significant potential to expand our current JORC resource at La Paz, which has the potential to be one of the largest rare earths projects in North America, making our asset significant in the development of the US domestic rare earths supply chain.
“I’d like to again extend my thanks to the American Rare Earths team and our contractors who worked safely and conscientiously to complete this drill program out at the site in Arizona, including our geologists who are now planning our next steps to advance this large-scale project.”
Assay Results
The first round of assay results for four holes (LP22-SW02, LP22-SW04, LP22-SW05, LP22-SW07) from the drilling campaign conducted in the La Paz, AZ, claim area during the beginning of 2022 indicate promising levels of rare earth enrichment. Several key relationships and interesting points can be elucidated from the results, which include:
- Preferential enrichment of the mylonite, ultra-mylonite, and cataclasite lithologies.
- The highest TREO values are found in thin clay bands from LP22-SW04 (741 ppm).
- Certain mafic dikes (only at LP22-SW04) show considerable enrichment.
- Certain quartz veins (only at LP22-SW05) show moderate enrichment.
- Little to no rare earth enrichment found in the granodiorite and monzonite lithologies of the Lower Plate.
