Appia Unveils Significant REE, Cobalt and Scandium Assay Results From 47 RC Drill Holes at the Buriti Target Within Its PCH IAC REE Project, Brazil

February 20, 2024 (Source) — Appia Rare Earths & Uranium Corp. (CSE: API) (OTCQX: APAAF) (FSE: A0I0) (MUN: A0I0) (BER: A0I0) (the “Company” or “Appia“) is pleased to report substantial results from a comprehensive exploration campaign, comprising a total of 47 Reverse Circulation (RC) holes as part of our 2023 drilling program in the Buriti REE Target. This target spans approximately 2 km by 1.2 km and is open to the south. The average drill hole depth was 14 metres, with a total weighted average grade of 853 parts per million (ppm) Total Rare Earth Oxide (TREO), 148 ppm Cobalt Oxide (CoO), and 67 ppm Scandium Oxide (Sc2O3) across all 47 drill holes. Scandium is most commonly used in aluminum-scandium alloys for aerospace industry components and for specialized sports equipment such as bicycle frames. Current Scandium average metal price, provided by the Institute for Rare Earths and Metals AG, is US$3,100.00/Kg (99.99% purity) and US$5,200.00 (99.999% purity). Cobalt is primarily used in lithium-ion batteries and in the manufacture of magnetic, wear-resistant and high-strength alloys.

Stephen Burega, President, stated, “There is significant potential in this newly identified REE mineralized zone. While the Buriti Zone has a completely different geological setting from the Target IV alkaline breccia to the north, we continue to see impressive REE results with the addition of significant Scandium and Cobalt values within the same drill holes. Drill holes PCH-RC-116 and PCH-RC-130, both remaining open at depth, highlight this potential. As previously reported, a standout among the analyses is hole PCH-RC-116, exhibiting mineralization averaging 2,109 ppm TREO, 272 ppm CoO, and 128 ppm Sc2O3 to a depth of 24 metres from surface.” (Click HERE for press release dated December 12, 2023).

    • 1,043 ppm or 0.1 % TREO, 332 ppm MREO, 249 ppm CoO, and 124 ppm Sc2O3 across 7 m (from 6-13 m).

The clay/saprolite hosted Buriti REE Target is underlain by mafic and ultramafic lithologic units associated with a Cretaceous-age regional alkaline complex. Despite Buriti’s proximity to the south of Target IV, where the lithology consists of granites and alkali breccias, this new target is predominantly composed of intensively weathered gabbro, diorite and pyroxenite.

Tom Drivas, CEO, commented: “Having surpassed a milestone of over 300 combined auger, reverse circulation, and diamond drill holes to date, the Company has commissioned SGS Canada to deliver in the coming weeks a NI 43-101 Technical Report on the PCH Project including a Mineral Resource Estimate (MRE) on the Target IV and Buriti zones.”

Appia is continuing to explore additional targets through an ongoing auger drilling program across the expansive 40,963.18 Ha of the PCH property.

Appia will be participating at this year’s Prospectors and Developers Association of Canada’s (PDAC) event from March 3-6^th 2024 at the Metro Toronto Convention Centre. Please visit our booth #2715. Also, Stephen Burega will also be presenting the Appia Corporate Update on March 6^th at 10:50 am during the Electric Materials 2 session located in room 801B.

QA/QC

Reverse circulation (RC) drill holes are vertical and reported intervals are true thickness. The material produced from drill holes are sampled at one metre intervals, resulting in average sample sizes of 5-25 kg. A small representative specimen was taken from each sample bag and placed into a chip tray for visual inspection and logging by the geologist. Quartering of the material was performed at Appia’s logging facility using a riffle splitter and continued splitting until a representative sample weighing approximately 500g each was obtained, bagged in a resistant plastic bag, labeled, photographed, and stored for shipment.

The bagged samples are sent to the SGS laboratory in Vespasiano, Minas Gerais. In addition to the internal QA/QC of the SGS Lab, Appia includes its own control samples in each batch of samples sent to the laboratory.

Quality control samples, such as blanks, duplicates, and standards (CRM) were inserted into each analytical run. For all analysis methods, the minimum number of QA/QC samples is one standard, one duplicate and one blank, introduced in each batch which comprise a full-length hole. The rigorous procedures are implemented during the sample collection, preparation, and analytical stages to insure the robustness and reliability of the analytical results.

All analytical results reported herein have passed internal QA/QC review and compilation. All assay results of RC samples were provided by SGS Geosol, an ISO/IEC 17025:2005 Certified Laboratory, which performed their measure of the concentration of rare earth elements (REE) analyses by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) analytical methods.
