“These exceptional drilling results have confirmed the potential of Target IV,” stated Stephen Burega, president. “The assay results received to date showcase substantial mineralization across 100% of the drill holes.”
Tom Drivas, CEO, said, “It’s very exciting to witness the PCH Ionic Clay project’s potential increasing through this Phase 1 drilling campaign with the average depth of mineralized zones increasing to 13 metres while consistently delivering extraordinary overall assay values which, in many cases, are from top to bottom of the hole.”
He continued, “Ionic Clay Rare Earths Deposits are usually found within the top 10-20m from surface; they are easier to mine, more environmentally friendly because they contain low or no radioactivity; exhibit simpler metallurgy therefore easier and cheaper to process; and contain good amounts of both the very valuable heavy and light magnet rare earths that are in high demand for cleaner electrification and use in a large number of high tech applications.”
The PCH Ionic Clay Project drilling has resulted in 17 holes with a weighted average value of 1,566 ppm TREO, which is comparable to, or surpasses, other well-known international deposits. “This initial batch of samples has revealed MREO that account for approximately 25% of TREO, producing notable overall values up to 1,189 ppm. We have identified high-grade values that are exceptional in terms of both width and grades,” stated Carlos Bastos, Brazilian Qualified Person and Geology Manager.
Target IV marks a significant milestone for Appia’s PCH Ionic Clay project, and the Company eagerly anticipates receiving further assay results from the SGS Geosol labs. “These results reaffirm our commitment to exploring the entire PCH project area which covers an impressive 17,551 hectares with a significant area still open to bluesky early-stage exploration, and we look forward to sharing more exciting developments in the near future,” commented Stephen Burega.

Background on the PCH Project
The PCH 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 the potential for REEs within lateritic ionic adsorption clays and Niobium.
Reverse circulation (RC) drill holes are sampled at one metre intervals, resulting in higher average sample size of 5-25 kg. A small representative specimen was taken from each sample bag and placed into a chip tray for visual inspection and logging by the geologist. Quartering 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 samples were sent to the SGS laboratory in Vespasiano, Minas Gerais. Despite the SGS Lab owning internal QA/QC, Appia has used its own control samples in each batch sent to the laboratory.
Quality control samples, such as blank, duplicate, and standard (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 every batch which comprise a full-length hole. The rigorous procedures implemented during the sample collection, preparation, and analysis stages underscore the robustness and reliability of the analytical results obtained.
All analytical results reported herein have passed internal QA/QC review and compilation. All assay results of RC 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) analyses by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) analytical methods.
