APPIA REPORTS HIGH-GRADE TOTAL RARE EARTH OXIDE RESULTS UP TO 22,339 PPM OR 2.23 per cent ON DIAMOND DRILL HOLE No.1 WITHIN TARGET IV AT PCH IAC PROJECT, BRAZIL

Appia Rare Earths & Uranium Corp. has released results from its 2023 diamond drill hole (DDH) No. 1 in the NE zone within target IV at its PCH IAC REE project in Brazil. The exploratory drill hole aimed to assess the continuity of the alkali breccia present through depth, reaching a total depth of 243.25 metres. Results have revealed a true thickness of approximately 217 metres, inclined at minus 63 degrees.

Stephen Burega, president, commented: "The findings from the ionic clay and saprolite weathered profile on PCH-DDH-001 underscore the exceptional potential of the target zone. The weathered profile along the hole extended to approximately 20 metres of true thickness yielding concentrations of 5,548 ppm [parts per million] or 0.55 per cent total rare earth oxide (TREO), 1,420 ppm or 0.14 per cent magnet rare earth oxide (MREO). The results confirm the ultrahigh-grade nature of the upper levels, including concentrations reaching up to 22,339 ppm or 2.23 per cent TREO, 6,204 ppm or 0.62 per cent MREO, and 2,074 ppm or 0.21 per cent heavy rare earth oxide (HREO) across two metres from a depth of two m to four m."

Highlights:

• Composite results across 243.25 metres:
  • 1,901 ppm or 0.19 per cent TREO, including 457 ppm or 0.05 per cent MREO, 143 ppm or 0.01 per cent HREO, and 1,757 ppm or 0.18 per cent light rare earth oxide (LREO;
• Composite results from 0-22.25 metres:
  • 5,548 ppm or 0.55 per cent TREO, including 1,420 ppm or 0.14 per cent MREO, 460 ppm or 0.05 per cent HREO, and 5,099 ppm or 0.50 per cent LREO;
• Composite results 0-9 metres:
  • 10,247 ppm or 1.02 per cent TREO, 2,672 ppm or 0.27 per cent MREO, 867 ppm or 0.09 per cent HREO, and 9,380 ppm or 0.94 per cent LREO, including:
    • 22,339 ppm or 2.23 per cent TREO, 6,204 ppm or 0.62 per cent MREO, 2,074 ppm or 0.21 per cent HREO, and 20,265 ppm or 2.03 per cent LREO (from two to four m);
• Composite results 25.50-52 metres:
  • 2,168 ppm or 0.22 per cent TREO, 518 ppm or 0.05 per cent MREO, 153 ppm or 0.01 per cent HREO, and 2,015 ppm or 0.20 per cent LREO;
• Composite results 58-140 metres:
  • 1,648 ppm or 0.16 per cent TREO, 378 ppm or 0.04 per cent MREO, 109 ppm or 0.01 per cent HREO, and 1,538 ppm or 0.15 per cent LREO;
• Composite results 164.30-243.25 metres (EOH):
  • 1,369 ppm or 0.13 per cent TREO, 329 ppm or 0.3 per cent MREO, 115 ppm or 0.01 per cent HREO, and 1,255 ppm or 0.13 per cent LREO.

"Appia's DDH-001 reveals more than 26 metres with over 2,000 ppm TREO below the saprolite. The mineralized breccia indicates in most of the intervals expected concentration of REE common to carbonatitic rocks that serves as a source for the enrichment in REE found on the ionic clay interval (zero to 22.25 metres). Some samples below 22.25 metres returned grades above 4,000 ppm TREO, offering opportunities for exploratory investigation into the hard-rock depths. With over 2,000 metres drilled, the total 2023 drilling campaign consisted of 147 reverse circulation (RC) holes, one DDH and over 200 exploratory auger holes, the PCH project continues to demonstrate significant mineralization and high-grade REE contents, validating our strategic approach," adds Mr. Burega.

The company remains committed to advancing exploration activities at its PCH project with its continuing auger drilling program and looks forward to providing updates on the National Instrument 43-101 technical report and maiden mineral resource estimate in collaboration with SGS Consultants.

Appia will be participating at this year's Prospectors and Developers Association of Canada's (PDAC) event from March 3 to 6, 2024, at the Toronto Convention Centre. You are invited to visit the Appia booth No.2715. Mr. Burega will also be presenting the Appia corporate update on March 6 at 10:50 a.m. during the Electric Materials 2 session located in room 801B.

QA/QC (quality assurance/quality control)

Diamond drill holes (DDH) can be vertical or inclined. If vertical, the reported intervals are true thickness. Inclined DDH true thickness need to be calculated based on the hole inclination angle given by the survey executed in the hole. The core produced from drill holes are described, the intervals are chosen and the core split and sampled at regular intervals within the same lithologic unit. The samples are bagged in a resistant plastic bag, labelled, photographed and stored for shipment.

The 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. 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 DDH 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.
