April 16, 2024 (Source) — Appia Rare Earths & Uranium Corp. (CSE: API) (OTCQX: APAAF) (FSE: A0I0) (MUN: A0I0) (BER: A0I0) (the “Company” or “Appia”) announced today that an independent technical report prepared in accordance with National Instrument 43-101 (“NI 43-101“) has been filed for the PCH ionic adsorption clay (IAC) project (the “PCH Project“) located in the State of Goiás, Brazil. The report entitled ‘Technical Report on the Maiden Mineral Resource Estimate for The PCH Project, State of Goiás, Brazil‘ dated April 15th, 2024 with an effective date of February 1, 2024 (the “PCH MRE Report“). The PCH MRE Report was co-authored by Yann Camus, P.Eng., Marc-Antoine Laporte, P.Geo., M.Sc., and Sarah Dean, P.Geo., of SGS Canada Inc. (“SGS“), all of whom are independent qualified persons under NI 43-101. The PCH MRE Report is available for review on SEDARplus (www.sedarplus.com) and the Company’s website www.appiareu.com.

There are no material differences in the PCH MRE Report from those results disclosed in the Company’s press release issued March 1, 2024. (Click Here).

Stephen Burega, President, commented, “The PCH MRE Report has outlined both exceptional grade and volume across both Target IV and Buriti zones which cover a total area of approximately 480 hectares. Within Target IV Appia has identified a high-grade zone with an inferred resource totalling 13.5 Mt at an average grade of 7307 parts per million (PPM) TREO.”

He continued, “The data generated from the first 300 drill holes at PCH has provided our team with a strong geological signature to track and confirm additional high-grade mineralization at newly identified ionic adsorption clay targets across the remaining tenements which encompass a very large area of over +40,000 hectares. The phase II auger drilling program is currently well underway, and we look forward to reporting on results as data becomes available.”

The Mineral Resource Statement prepared by SGS for the PCH Project is detail below.

  1. The MRE has an effective date of the 1st of February 2024.
  2. The Qualified Person for the MRE is Mr. Yann Camus, P.Eng., an employee of SGS.
  3. The MRE provided in this table were estimated using current Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Standards on Mineral Resources and Reserves, Definitions and Guidelines.
  4. Mineral Resources that are not Mineral Reserves have not demonstrated economic viability. Additional drilling will be required to convert Inferred and Indicated Mineral Resources to Measured Mineral Resources. There is no certainty that any part of a Mineral Resource will ever be converted into Reserves.
  5. All analyses used for the MRE were performed by SGS GEOSOL by ICM40B: Multi Acid Digestion / ICP OES – ICP MS and by IMS95R: Lithium Metaborate Fusion / ICP-MS.
  6. MRE are stated at a cut-off total NSR value of 10 US$/t. The full price list and recovery used to estimate the NSR is in Table 2. The estimated basket price of TREO is US$26.98.
  7. GEOVIA’s WhittleTM software was used to provide an optimized pit envelope to demonstrate reasonable prospection for economic extraction. Preliminary pit optimization parameters included overall pit slope of 30 degrees, in-pit mining costs of $2.10, processing and G/A costs of $9/t, and overall mining loss and dilution of 5%. Full details of the preliminary pit-optimization parameters can be found in Table 2. The basket price and oxides price list in Table 2 are based on forward-looking pricing. These future prices are predicted based on market trends, economic forecasts, and other relevant factors. The actual prices may vary depending on changes in these factors.
  8. Figures are rounded to reflect the relative accuracy of the estimate and numbers may not add due to rounding.
  9. Resources are presented undiluted and in situ, constrained within a 3D model, and are considered to have reasonable prospects for eventual economic extraction.
  10. Bulk density values were determined based on physical test work and assumed porosities for each type of material.
  11. Total Rare Earth Oxides: TREO = Y2O3 + Eu2O3 + Gd2O3 + Tb2O3 + Dy2O3 + Ho2O3 + Er2O3 + Tm2O3 + Yb2O3 + Lu2O3 + La2O3 + Ce2O3 + Pr2O3 + Nd2O3 + Sm2O3.
  12. Magnetic Rare Earth Oxides: MREO = Sm2O3 + Tb4O7 + Dy2O3 + Pr6O11 + Nd2O3.
  13. Heavy Rare Earth Oxides: HREO = Sm2O3 + Eu2O3 + Gd2O3 + Tb4O7 + Dy2O3 + Ho2O3 + Er2O3 + Tm2O3 + Yb2O3 + Lu2O3.
  14. The MRE may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

Phase II Auger Drilling Across the PCH Project

The Company also wishes to announce the expansion of its auger drilling exploration program aimed at the identification of new Ionic Adsorption Clay (IAC) targets on the remaining claims to the east and north of Target IV and Buriti Zones, on its 40,963.18 ha. PCH project within the Goiás State of Brazil. The geological environment of the remaining tenements is equivalent to the one characterized on Target IV, and it will be tested during the Phase II auger drilling program.

The selection of the new target zones to be tested was based on three primary factors including:

  1. A similar geological formation which the Company has identified as the Iporá Granite;
  2. Similar weathering profile development with well-developed transition zone between Pedolith and Saprolites where the Ionic Adsorption Clays occur; and
  3. Positive showing of the related gammaspectometric geophysical response.
