Appia Reports Extraordinary Assay Drill Results From Its PCH Ionic Clay Project, Brazil
Appia Reports Extraordinary Assay Drill
Results From Its PCH Ionic Clay Project, Brazil
Reverse Circulation Drill Hole Returns 24 Metres Of
Mineralization Averaging 27,188 ppm or 2.72% Total Rare Earth
Oxides From Surface
Toronto, Ontario--(Newsfile Corp. - October 31, 2023) -
Appia Rare Earths & Uranium Corp. (CSE:
API) (OTCQX: APAAF) (FSE: A0I0.F) (FSE: A0I0.MU) (FSE: A0I0.BE) (the "Company" or
"Appia")
is thrilled to announce a groundbreaking discovery of an exceptional high-grade Total Rare
Earth Oxides (TREO) intersection extending the known area of Target IV. Hole PCH-RC-063 contains
unique high grades and depth of mineralization, spanning an impressive 24 metres from top to bottom,
and remains open at depth.
Summary:
27,188 parts per million (ppm) or 2.72% TREO over 24 metres
Including 6,293 ppm or 0.63% Magnet Rare Earth Oxides (MREO)
Including 1,369 ppm or 0.14% Heavy Rare Earths Oxides (HREO)
PCH-RC-63 totalled 24 metres depth and is mineralized throughout the entire hole from
surface, and remains open at depth.
Notably, several elements surpassed the upper detection limit of the assay method being
used, and updated results
will be reported once received.

"These drill results are the highest TREO grades detected on the PCH property to date," commented
Tom Drivas, CEO. "The data released today reveals an unprecedent concentration of TREO over the
entire hole, and even more impressive is that the hole remains open at depth, suggesting significant
potential for further mineralization."
"This extraordinary RC hole confirms the extension of the initial Target IV area to the West and has
increased the average thickness and total depth of the highly mineralized PCH ionic clay horizon," said
Stephen Burega, President. "These high concentrations of TREO are very uncommon, and may be the
first indications of a larger high-grade mineralized zone. Lastly, we have not yet tested the total thickness
of this zone as the RC drilling was stopped at the water table."
"The consistency of grades is truly spectacular. At the bottom one metre of the hole, in sample F485895,
we observed grades of 26,882 ppm of TREO, 5,897 ppm of MREO, and 1,245 ppm of HREO," stated
Carlos Bastos, Geology Manager and Appia's Brazilian Qualified Person. "The assay results from PCH-
RC-063 are highly promising, revealing sustained mineralization of essential elements including Terbium
(Tb), Dysprosium (Dy), Neodymium (Nd), and Praseodymium (Pr). Notably, several elements surpassed
the upper detection limit of the assay method being used, and updated results will be reported once
received."
In light of these findings, Appia has commissioned a comprehensive analyses for each rare earths oxide
using the methods IMS95RS and ICP95A from SGS Geosol Lab to further understand the potential
implications that this level of mineralization could have on the project.
Appia will provide timely updates to shareholders and the general public as assay results are received
from the remaining 129 RC, 106 Auger, and 1 diamond drill holes.

Background on the PCH Project
The PCH Project is located within the Tocantins Structural Province in the Brasília Fold Belt, more
specifically, the Arenópolis Magmatic Arc. The PCH Project is 17,551.07 ha in size and located within
the Goiás State of Brazil. It is classified as an alkaline intrusive rock occurrence with highly anomalous
REE and Niobium mineralization. This mineralization is related to alkaline lithologies of the Fazenda
Buriti Plutonic Complex and the hydrothermal and surface alteration products of this complex by
supergene enrichment in a tropical climate. The positive results of the recent geochemical exploration
work carried out to date indicates the potential for REEs within lateritic ionic adsorption clays and
Niobium.
QA/QC
Reverse circulation (RC) drill holes are sampled at one metre intervals, resulting in higher 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 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 samples were sent to the SGS laboratory in Vespasiano, Minas Gerais. In addition to the internal
QA/QC of the SGS Lab, Appia has used its own control samples in each batch 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 every batch which comprise a full-length hole. The rigorous
procedures implemented during the sample collection, preparation, and analysis stages underscore the
robustness and reliability of the analytical results obtained.
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.
