Appia Announces Significant Results from Two Additional Exploration New Targets Electra and Maia at PCH Project

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.

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. A 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 1st, 2024, the Company announced its maiden Mineral Resource Estimate (MRE) on Target IV and the Buriti Zone (Click here for the Press Release), and the companion NI 43-101 technical report on the PCH Project was filed on April 16th, 2024. (Click here for the Press Release)

QA/QC

Auger drill holes are vertical and reported intervals are true thickness. The material produced from drill holes are sampled at one metre intervals, resulting in average sample sizes of 5-10 kg. Quartering of the material 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 bagged samples are sent to the SGS laboratory in Vespasiano, Minas Gerais. In addition to the internal QA/QC of the SGS 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 one standard, one duplicate and one blank, introduced in each batch which comprise a 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 Auger 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) with the IMS95R analytical method that uses lithium metaborate fusion prior acid dissolution and Inductively Coupled Plasma Mass Spectrometry (ICP-MS).
