APPIA REPORTS REMARKABLE DRILLING RESULTS; DOUBLES DEPTH OF MINERALIZED ZONES AT THE PCH IONIC CLAY PROJECT, BRAZIL

Appia Rare Earths & Uranium Corp. has released results from the first 17 drill holes out of 147 completed to date from the reverse circulation (RC) drilling campaign at its PCH ionic clay project in Goias state, Brazil. The results from the first 17 RC drill holes represent a significant doubling in average depth of mineralized zones to 13 metres with overall weighted average grades of 1,566 parts per million (ppm) total rare earth oxides (TREO) which is comparable with, or surpasses, other well-known international deposits.

Summary:

• Reverse circulation (RC) drill holes assayed: The first 17 RC drill holes of the phase 1 drill program are all rare earth element (REE) mineralized. A total of 147 holes have been completed to date with an accumulated total of 2,019 metres drilled.
• Average depth doubled: The average depth of RC drilling is over 13 metres from surface, representing a significant doubling in average depth of the mineralized zones.
• Outstanding grades: The results exhibit overall grades similar to or surpassing known deposits, with remarkable high-grade mineralization identified, including:
  • PCH-RC-001 from zero m to 15 m end of hole (EOH):
    • 1,914 ppm TREO and 510 ppm magnet rare earth oxides (MREO), or 27 per cent of TREO, including nine m at 2,300 ppm TREO and 632 ppm MREO, or 27 per cent of TREO from two m to 11 m;
    • 291 ppm heavy rare earth oxides (HREO), or 15 per cent of TREO, including nine m at 366 ppm, or 16 per cent of TREO;
  • PCH-RC-002 from zero m to 15 m (EOH):
    • 2,671 ppm TREO and 605 ppm MREO, or 23 per cent of TREO, including six m at 5,389 ppm TREO and 1,189 ppm MREO, or 23 per cent of TREO from eight m to 14 m;
    • 220 ppm HREO, or 8 per cent of TREO, including six m at 412 ppm HREO, or 8 per cent of TREO;
  • PCH-RC-008 from zero m to 18 m (EOH):
    • 2,752 ppm TREO and 741 ppm MREO, or 27 per cent of TREO, including 15 m at 3,084 ppm TREO and 839 ppm MREO, or 27 per cent of TREO from two m to 17m;
    • 404 ppm HREO, or 15 per cent of TREO, including 15 m at 460 ppm HREO, or 15 per cent of TREO;
  • PCH-RC-009 from zero m to 15 m (EOH):
    • 3,277 ppm TREO and 804 ppm MREO, or 25 per cent of TREO, including 12 m at 3,594 ppm TREO and 886 ppm MREO, or 24 per cent of TREO from one m to 13 m;
    • 251 ppm HREO, or 8 per cent of TREO, including 12 m at 275 ppm HREO, or 8 per cent of TREO;
  • PCH-RC-011 from zero m to 15 m (EOH):
    • 3,717 ppm TREO and 913 ppm MREO, or 25 per cent of TREO, including 11 m at 4,182 ppm TREO and 1,035 ppm MREO, or 25 per cent of TREO from zero m to 11 m;
    • 286 ppm HREO, or 8 per cent of TREO, including 11 m at 327 ppm HREO, or 8 per cent of TREO.

"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 100per cent of the drill holes."

Tom Drivas, chief executive officer, 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 to 20 m 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 with, or surpasses, other well-known international deposits. "This initial batch of samples has revealed MREO that account for approximately 25 per cent 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 blue-sky early-stage exploration, and we look forward to sharing more exciting developments in the near future," commented Mr. Burega.

Background on the PCH project

The PCH project is located within the Tocantins structural province in the Brasilia fold belt, more specifically, the Arenopolis magmatic arc. The PCH project is 17,551.07 ha in size and located within the Goias 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 indicate 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 five to 25 kilograms. 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 500 grams each was obtained, bagged in a resistant plastic bag, labelled, photographed and stored for shipment.

The samples were sent to the SGS laboratory in Vespasiano, Minas Gerais. Despite the SGS Lab owning internal quality assurance/quality control, Appia has used its own control samples in each batch sent to the laboratory.

Quality control samples, such as blank, duplicate and standard (certified reference material), 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 its measure of the concentration of rare earth elements (REE) analyses by inductively coupled plasma mass spectrometry (ICP-MS) analytical methods.
