Halleck Creek Project Update
13 Giugno 2024 - 2:03PM
American Rare Earths Ltd. (
ASX: ARR | OTCQX: ARRNF | ADR:
AMRRY) (“ARR” or the
“Company”) is
pleased to provide a project update around previously announced
project milestones and announce upcoming exploration drilling at
the Halleck Creek Project. Under the DARPA Environmental Microbes
as a BioEngineering Resource (EMBER) program, Phase II was recently
awarded an additional US$4.6 million in R&D funding for
continued studies. This is noteworthy as prior work from this
research has been utilized in the current processing flowsheet,
using gravity separation techniques developed in the research, and
the R&D continues to utilise Halleck Creek ore2.

ASX Announcement, “American Rare Earths Announces Breakthrough
Metallurgical Results”, 22 January 2024.
Donald Swartz, CEO of American Rare
Earths, commented:“I am pleased to announce our continued
project execution to de-risk the project. At the time of our
institutional placement in February, we outlined the use of
proceeds to accelerate development to include additional drilling,
metallurgical testwork, project studies, and permitting. As we
enter the 2025 fiscal year, we do so ahead of schedule. Through the
Company’s involvement in the DARPA initiative, our flowsheet has
improved, and I’m excited about the future. The planned drilling
will allow ARR to upgrade our resource estimates and provide data
for advancing studies in FY2025. The mineral processing and
leaching testwork is designed to refine our current flowsheets. The
preliminary baseline environmental studies are the first steps
towards responsible mine development at the Cowboy State Mine.”
Project Update
- The Company is mobilizing drillers
so drilling can commence in July 2024. The plans for the Cowboy
State Mine area consist of drilling approximately 23 holes (12 RC
holes and 11 HQ core holes) for a total of 2,470 meters (8,100
feet) (Figure 1).
- ARR has engaged WWC Engineering
(WWC), from Sheridan, Wyoming, to oversee and conduct baseline
environmental data collection activities at the Cowboy State Mine
area. These baseline studies include commencing detailed vegetation
and animal monitoring surveys. Additional baseline environmental
studies will commence after consultation with the Wyoming
Department of Environmental Quality – Land Quality Division.
- ARR continues to refine mineral
processing flowsheets with ongoing work at Mineral Technologies and
SGS Canada. Mineral Technologies ran approximately 400 kg of
Halleck Creek core across spiral separators showing distinct
separation between the material (Figure 2 ). Mineral Technologies
collected 53 samples and submitted them for assay with ALS Global,
with results pending.
- SGS Canada is performing
high-pressure grinding roll (HPGR), gravity separation, wet-high
intensity magnetic separation, and electrostatic separation tests
on approximately 75kg of Halleck Creek core. The SGS testwork is
designed to build upon separation testing performed by Wood PLC in
2023, with a focus on gravity separation as the primary separation
method with results expected in Q3 2024.
- ARR is developing processing and
leaching test programs and will be using approximately 3 tonnes of
available core samples from Halleck Creek and core samples
collected during the July 2024 drilling at the Cowboy State Mine
area. The processing and separation testwork will be based on the
results of current Mineral Technologies and SGS Canada testing and
is expected to commence in Q3 2024.
- SGS Canada have developed a
comprehensive testwork plan focusing on leaching, impurity removal
and preliminary rare earth oxide processing with work to commence
in Q3/Q4 2024.
