American Rare Earths Limited (ASX: ARR, OTCQB: ARRNF) has completed a successful maiden exploration drill programme at the Halleck Creek Rare Earths Project in Wyoming.
The campaign provided encouraging preliminary data from the Exploration Target Area. ARR drilled 917 metres (3,008 feet) and collected 822 samples from nine holes in the Red Mountain and Overton Mountain zones of the larger Red Mountain Pluton, with core recovery from most holes exceeding 99%.
“We are extremely excited about what we are seeing at this world class project as it continues to exceed our expectations,” MD and CEO Chris Gibbs said.
“I want to congratulate the entire team who worked enthusiastically and safely out in Albany County to give us the first below surface insights from Halleck Creek.
“The information from these drill holes will determine the regional extent of mineralised depth following the continued positive surface sample results from the project.
“Based on the sheer size, scale and grade of this deposit, Halleck Creek has the potential to be one of the largest rare earths projects in the US.
“Since acquiring this asset we have significantly increased the footprint and continue to see high grade mineralisation over a large area.
“We’re now looking forward to the assay results, expected in late June or July, and based on the preliminary data we’re already planning our next phase of work.”
The Wyoming project’s rare earth elements (REEs) occur in allanite containing the full suite of naturally occurring REEs, significantly high value magnet REEs neodymium, praseodymium, dysprosium and terbium. The Halleck Creek allanite is associated with clinopyroxene quartz monzonite (CQM) rocks which generally contain the highest REE grades.
The completion of the maiden drilling campaign follows 118 surface sample results returned late last month that prompted ARR to stake claims across an additional 1,191ha (2943.025 acres). That brings the Halleck Creek Rare Earth Project to 2,449ha (6051.6 acres) and ARR’s total area under exploration across the US to 5260ha (12997.7 acres).
Similar to surface samples collected from Halleck Creek in 2018 and 2021, those announced on April 26th demonstrated high-grade REE mineralisation rich in Neodymium and Praseodymium (NdPr), with very low penalty elements Thorium and Uranium.
The Halleck Creek Rare Earths Project has an Exploration Target estimated to contain 308 to 385 million tonnes of Rare Earth Oxide (REO) mineralised ore ranging in grade from 2,330 to 2,912 ppm Total Rare Earth Oxide (TREO).
The company is now planning additional detailed geological mapping and geochemical sampling over Halleck Creek claims. This work is scheduled to start May 2022 with focus on the Red Mountain portion of the RMP’s rock outcrops, plus the newly staked tenement areas. The aggregate results will be used to plan future drilling as the Company explores the prospect for potential development of a Maiden Resource.
