American Rare Earths further extends zone at Halleck Creek, Wyoming

Rhea-AI Summary

American Rare Earths (OTCQB: ARRNF) has reported promising assay results from its Halleck Creek Rare Earths project in Wyoming. Results from 600 samples across six reverse circulation drill holes confirm rare earth mineralization extending to 175.5 meters, 75.5% deeper than previous targets. Notably, 27% of the rare earths comprise highly valuable magnetic elements. Significant intercepts include 4,303 ppm over 169.5 meters and 6,948 ppm over 37.5 meters. The current assay results bolster the potential for a large-scale resource, reinforcing the project's viability in meeting growing demand in the rare earth market, projected to reach US$20 billion by the mid-2020s.

New assays show high rare earth grades from surface to depths of 175.5 meters

PHOENIX, Feb. 13, 2023 (GLOBE NEWSWIRE) -- American Rare Earths (ASX: ARR | OTCQB: ARRNF | FSE: 1BHA) or the ‘Company’ is pleased to announce assay results for 600 samples from six reverse circulation (RC) holes at the Halleck Creek Rare Earths project in Wyoming.

Highlights

• Assays confirm rare earth mineralization to new depths of 175.5 meters
• Depth of mineralization is 75.5% deeper than original exploration target
• 27% of rare earths includes highly valuable magnetic rare earth elements
• Deposit remains open and with significant upside potential
• Major intercepts include:
  • HC22- RM015 averages 4,303 ppm over 169.5 meters.
  • HC22- RM022 averages 6,948 ppm over 37.5 meters.
  • HC22-RM007 averages 3,966 ppm TREO over 150 meters, over the complete length of the hole.

The Company now has complete assay data for 15 holes and partial assays for three (3) additional holes in the Red Mountain project area at the Halleck Mining district.

Since the previous release, the Company has received the remaining assay results from HC22-RM015. These confirm enriched rare earth mineralization over an interval length of 169.5m (487 feet) to a total depth of 175.5m (576 feet). This is an increase of 75.5% over the depth drilled for the maiden drill campaign of 100 meters. Please note, the exploration target of 1.01 to 1.27 billion tonnes announced to market on September 1, 2022, was also based off a depth of 100 meters. Encouragingly, mineralization remains open at depth.

Drill hole HC22-RM007 showed outstanding results with an average total rare earths oxide (TREO) value of 3,996 ppm from surface along the entire 150m length of the hole. Likewise, drill hole HC22-RM022 contains an interval of 37.5m with an average grade of 6,948 ppm TREO. The Company awaits the final results for three additional holes in the Red Mountain project area and 20 holes in the Overton Mountain project area. ALS laboratories in Vancouver, British Columbia performed the analysis.

Chief Executive Officer and Managing Director Chris Gibbs said he was delighted to announce the recent assay news.

“These are outstanding results and we have consistently seen mineralization from surface to depths of 150 meters. It is extremely encouraging to see mineralization now extend to at least 175.5 meters. This is a 75.5% increase in depth from the maiden drill campaign and well exceeds the basis of the original exploration target of 100 meters.

We are encouraged about the prospect of a significant rare earth structure at depth and are looking forward to conducting further drilling to determine how deep the deposit is. However, our priority is to establish a significant JORC resource, and at depths of 175.5 meters we already see the basis for a large scale, long life open pit mine on the magnitude of the major copper/gold porphyry deposits, so often seen in the Western USA.

Let’s keep in mind, these recent assay results are from the Red Mountain area, which is only one of seven zones we have identified in this massive rare earth district.

We’re eagerly anticipating the remaining drill assay results, including assays for the Overton Mountain zone which was also drilled during this most recent campaign.”

Assay Results
Preliminary assay results from 15 RC holes in the Red Mountain project area have an average TREO of 3,603 ppm. Magnetic rare earth oxides (MREO) including the valuable Neodymium and Praseodymium continue to comprise approximately 27% of the rare earths at Red Mountain.

18 RC holes were drilled in the Red Mountain project area, and an additional 20 holes were drilled in the Overton Mountain project area between October and December 2022.

The assay results demonstrate consistent rare earth mineralization associated with clinopyroxene quartz monzonite (CQM) and fayalite monzonite (FM) rocks of the Red Mountain Pluton (RMP).

Drill hole HC22-RM015 was drilled to 175.5 meters (576 feet) and consisted primarily of CQM. As previously released, the last sample in drill hole HC22-RM015 contains a TREO value of 3,665 ppm. Since the previous release, the Company received all assays for drill hole HC22-RM015. This hole has an average TREO value of 4,303 ppm over an interval of 169.5 meters (487 feet).

Average values for the penalty elements of Thorium and Uranium remain very low.
