Appia Announces Exceptional Overlimit Total
Rare Earth Oxide (TREO) Results From Its
Diamond Drilling Program at PCH Project in
Goias, Brazil

Toronto, Ontario--(Newsfile Corp. - March 10, 2025) - Appia Rare Earths & Uranium Corp.
(CSE: API)
(OTCQB: APAAF) (FSE: A0I0) (MUN: A0I0) (BER: A0I0)
(the "
Company
" or
"Appia"
) is excited to
announce the geochemical overlimit assay results of its diamond drilling program on the high grade
carbonatitic breccia located on the PCH project in the State of Goias, Brazil. The three drillholes (see
Map 1) intercepted substantial Total Rare Earth Oxide (TREO), Niobium Oxide (Nb2O5) and Phosphate
Oxide (P2O5) from the brecciated carbonatite intrusion identified in the Southwest Extension Zone of
Target IV.
A total 97 intervals from the total of 516 presented samples resulted with 'overlimit
readings' for La, and/or Ce, and/or Pr, and/or Nd, and/or Nb.
The full set of results are available
through this
LINK
. The PCH project hosts two distinct styles of mineralization - Ionic Adsorption Clay
(IAC) as well as hard rock carbonatitic breccia. Recent results from the IAC zone can be found by

Tom Drivas, CEO stated: "Today's re-assayed overlimit results further support the presence of an
extraordinary, high-grade mineralization found within a carbonatitic breccia zone located at the
Southwest Extension Zone of Target IV at the PCH project, and this is in addition to significant IAC rare
earths mineralization with good TREO results and excellent desorption and kinetics.
The original results
reported on January 22
nd
, 2025 highlighted that the high grade rare earths mineralization was from top
to bottom of each of the three drillholes, and today's results increase the average TREO grades by 19%
and the average Niobium grades by 23% from the original values reported. (

The results from the diamond drill holes are exceptional and would
rank 2

on the list of the best intercepts of the past year when compared to the recently reported results by
MinerDeck, which highlighted the top REE intercepts of 2024. (Please

including 22m@ 1.13% TREO 0.44% Nb2O5 from 138m
Increases the average TREO grades by 19% and average Niobium grades by 23% from the
original values reported.
A total 97 intervals from the total of 516 presented samples resulted with 'overlimit
readings' for La, and/or Ce, and/or Pr, and/or Nd, and/or Nb.
All three (3) Diamond Drillholes (DDH) ended in mineralization indicating a potential to extend the
zone at depth, northeast, northwest and southwest.
The PCH project has two distinct styles of mineralization - Ionic Adsorption Clay (IAC) as well as
hard rock carbonititic breccia.

The location of the PCH project is extremely favorable with easy access to road and power
infrastructure, and the Company enjoys a very friendly and supportive relationship with the local cattle
farming community.

QAQC
Drillholes are inclined and reported intervals are apparent thickness. The material produced from the
diamond drillholes are sampled at one metre intervals splitting the core in half, resulting in average
sample sizes of 2-3 kg. The other Half core is kept in storage for further tests. The original core was
logged and photographed.
The bagged samples are sent to the ALS laboratory in Goiânia, Goias for initial preparation and sent to
Lima Peru for final analysis. In addition to the internal QA/QC of the ALS 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
three
standards,
one
duplicate and
one
blank, introduced in each batch. Several batches were used to comprises the
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 DDH samples were provided by ALS, a Certified Laboratory, which performed their measure
of the concentration of rare earth elements (REE) with the ME-MS81 analytical method that uses lithium
borate fusion prior acid dissolution and Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Major
Element Oxides were done using ME_ICP06 analytical method using lithium borate fusion and
inductively coupled plasma atomic emission spectroscopy (ICP-AES). Au, Pt and Pd samples were
analysed using the fire assay method PGM-ICP27. Desorption analysis with ME-MS19 analytical
method was executed for the initial 35 metres of each drillholes with samples being leached with a
solution of Ammonium Sulphate at 0.5 molar, pH 4, room temperature for 20 minutes. The leached
solution content was analysed using ICP-AES/ICP-MS. (
