Appia Announces Significant Results from

Two Additional Exploration New Targets

Electra and Maia at PCH Project

Toronto, Ontario--(Newsfile Corp. - May 22, 2024) - Appia Rare Earths & Uranium Corp.

(CSE: API)

(OTCQX: APAAF) (FSE: A0I0) (MUN: A0I0) (BER: A0I0)

(the "

Company

" or

"Appia"

) announced

today the results from 2 newly identified exploration targets - Electra and Maia. A total of 196 samples

from 25 auger drill holes were assayed by SGS-GEOSOL Laboratories in Vespasiano, Brazil. The

results confirm again that the regolith developed over the Ipora Granite presented significant enrichment

of Heavy Rare Earth Oxides (HREO), indicative of the Ionic Adsorption Clay (IAC) rare earth elements

(REE) deposits similar to the Target IV zone already identified as IAC REE. This will be confirmed by the

desorption analysis which is currently underway.

Stephen Burega, President, commented, "Appia's geology team continues to identify significant new

target zones at the PCH project, and further our understanding of the IAC mineralization across the

overall project area.

The impressive HREO results now identified across multiple zones of homogeneous

mineralization highlights the true potential of the PCH project.

We are very pleased with what we have

accomplished to date and are moving quickly to our next phase of definition drilling, and the

commissioning of a Preliminary Economic Assessment (PEA) report including the expansion of the

existing maiden Mineral Resource Estimate. Management is working on many fronts to build strong

industry linkages and participate in international forums to support the next phase of project

development."

Highlights

The new targets are in the Central and Mid-western portion grouping of claims, Maia is located

approximately 7 km east-northeast from Target IV, and Electra 5 km north-northeast from Target IV

(see Figure 1).

The grade distribution signature found at depth in the auger drill holes is comparable with the

pattern commonly found on IAC REE deposits (see Figures 3, 4, 5 and 6).

The Electra and Maia targets cover an area of 395 and 321 hectares respectively. Currently, the

four new target zones (Merope, Taygeta, Maia and Electra) equal approximately 2,400 hectares in

total area (Figure 2). In comparison, the Target IV and Buriti zones, where Appia's maiden Mineral

Resource Estimate (MRE) was calculated, equal a total area of 483 hectares.

These first phase auger drill holes average 7.84 metres in depth, and the majority of drill holes

ended in mineralization leaving the interval open at depth.

Intercepts of all auger drill holes are presented in Table 1. The full set of results are included in this

Andre Costa, VP Exploration for Brazil, commented, "Once again we are seeing well-developed zones

with the same lithological development and distribution of REE mineralization within the regolith

associated with the weathered Ipora Granite that underlays a majority of the PCH project area.

representative group of samples from the Maia and Electra zones are being prepared for desorption

analysis.

Meanwhile, our ground-crews continued to delineate new targets zones and auger drill testing

will ensue across the +40,000-hectare property.

To date, Appia has only tested approximately 30% of

the total project area."

On March 1

, 2024, the Company announced its maiden Mineral Resource Estimate (MRE) on Target

IV and the Buriti Zone (
