Appia Announces Exceptional Overlimit Total

Rare Earth Oxide (TREO) Results From Its

Diamond Drilling Program at PCH Project in

Goias, Brazil

Drilling Confirms the Carbonatitic Breccia High Grade Zone

Mineralization

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. (

including 10m @ 5.68% TREO, 0.44% Nb2O5 from 42m

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. (
