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
Toronto, Ontario--(Newsfile Corp. - February 20, 2024) - 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

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."

The Lanthanum values used to convert to oxides were adjusted from 1.1688 to 1.1728 based on James Cook University standard. This change
explains the small difference for TREO values previously released.

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.
