Appia Provides Update on its Extensive

Drilling Program at its PCH Ionic Clay Project,

Brazil

Toronto, Ontario--(Newsfile Corp. - September 28, 2023) -

Appia Rare Earths & Uranium

Corp. (CSE: API) (OTCQX: APAAF) (FSE: A0I0)

(FSE: A0I0.F) (FSE: A0I0.MU) (FSE:

A0I0.BE) (the "Company" or "Appia")

is pleased to provide an update on the progress of its ongoing

drilling program to outline the extent of the mineralized zone at Target IV on its PCH Iconic Clay Project

in Brazil. To date, the Company has processed and sent 2,255 samples for analysis, from both the

Reverse Circulation (RC) and Auger drill programs, and expects to release results in the near future.

Summary:

Completed 232 drill holes for a total of 2847.5 metres, of which:

Reverse Circulation drilling: 147 holes totaling of 2,019 metres.

Auger drilling: 84 holes totalling of 585 metres.

Diamond drilling - Completion of 243.50 metres.

Logging and sampling is ongoing, and currently, 2,255 samples have been sent to SGS Geosol

laboratory for assaying.

"The reverse circulation (RC) drilling has averaged roughly 13 metres depth, often exceeding 20 metres

depth and encountering clayey materials in the majority of holes. Auger sampling, on the other hand, has

an average depth of about 7 metres, with samples collected every meter," stated Carlos Bastos,

Geology Manager and Brazilian QP. "And in specific cases, alternative methodologies have been

applied to gain a deeper understanding of the mineralized zones and analytical methods."

He continued, "With diamond, RC, and auger drilling activities running concurrently, the project has made

substantial advancements. Our team is exceptionally pleased with the productivity, geological insights,

and interpretation we have gathered thus far. We are confident that the forthcoming results from the SGS

laboratory will strengthen our belief that we are positioned within a significant rare earth element ionic

clay deposit."

"Appia's RC extensive drilling program at Target IV has reached a total of 147 holes, and we have now

completed the first phase of the multi-phase drilling initiatives across our +17,000 hectare PCH Ionic

Clay project in Goias State, Brazil," stated Stephen Burega, President. "Working within a very tight

timeline of just 51 days, our Brazilian team oversaw the program and reached an impressive 2,019

meters drilled and assays are now pending."

"The RC drill program has been augmented by exploratory auger drilling and sampling, along with

ground geophysics to enhance our comprehension of the subsurface composition and the potential

expansion of the known mineralized area of Target IV," he continued.

In addition, the Company is pleased to announce the successful conclusion of the 243.50-meter

diamond drill hole, which tested a strong magnetic anomaly at depth within the alkali breccia zone. Drill

core will now be logged and sampled to be sent to the SGS Geosol laboratory for assaying. Appia's

geologists and technicians follow strict quality assurance/quality control protocols for sample preparation

and shipment to the SGS Geosol laboratories in Brazil.

Tom Drivas, CEO of Appia, expressed his satisfaction with the project's progress, stating, "We are very

proud of the dedicated efforts of our team in Brazil. Operating succesfully, we have effectively covered a

significant area on our 100-meter spacing grid at Target IV. Furthermore, we have expanded to a 200-

meter spacing grid in adjacent areas and ventured into new prospective areas outside the known

deposit with auger drilling. The large land package of the PCH Project spans over 17,000 hectares

within a highly prospective region."

Background on the PCH Project

The PCH Ionic Adsorption Clay 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 great potential for REEs and Niobium within lateritic ionic adsorption

clays.
