Halleck Creek drilling program successfully completed by American Rare Earths

At its flagship Halleck Creek project, American Rare Earths has reported the successful completion of the development drilling program.

Halleck Creek drilling program

With a 1.43 billion t JORC resource, the Halleck Creek project was once reported to be the largest strategic rare earth project in the United States.


  • The 23-hole program, totaling 2389 meters, has been finished on time, and the assay results should be available in December 2023.
  • High grade zones were found, and XRF grades of high to 8,875 ppm were noted. De minimis amounts of uranium and thorium as well as enriched rare earth mineralization were confirmed in every drillhole included in the program.
  • On October 3, 2023, the business declared that enriched mineralization had been found to a minimum depth of 300 meters, which represents a 178% increase over earlier drilling and suggests the resource would be far larger than anticipated. The deposit is still open at depth and width, with just 25% of it having been drilled.
  • The company intends to improve its previously disclosed JORC resource after receiving its assay findings.
  • The company is shipping two t of core material acquired throughout the program to its partner laboratories so they may evaluate and measure the metallurgical properties using the proposed hydrometallurgical plant.

The primary goal of the drilling campaign was to confirm high-grade mineable area(s) in order to identify a sizable volume of measured and indicated resources. This can boost confidence as the company continues to develop its Halleck Creek future strategy and is required for resource reporting requirements. Building on the recently reported satisfactory metallurgical tests, core material from this drilling operation will be utilized to enhance the flowsheet design and provide cost estimates for a Preliminary Economic Analysis (PEA).

“This drilling campaign was an important first step on our development path,” American Rare Earths CEO Donald Swartz stated. “We will be sending the recovered core material to labs as our next course of action. In order to continue reducing project risk, concentrate will be prepared and then sent to multiple downstream testing facilities using our affordable processing technology. I would like to express my gratitude to our technical staff and geologists for their excellent management of this exploration program, which was finished on time and within budget.
