Appia reports exceptional TREO results from diamond drilling at PCH Project in Brazil

The PCH Project benefits from excellent infrastructure, including easy access to roads and power, and enjoys strong support from the local community.

Appia Rare Earths & Uranium Corp. has announced exceptional results from its diamond drilling program at the PCH Project in Goiás, Brazil. The drilling intercepted significant concentrations of Total Rare Earth Oxide (TREO), Niobium Oxide (Nb₂O₅), and Phosphate Oxide (P₂O₅) within a brecciated carbonatite intrusion in the Southwest Extension Zone of Target IV.

Key Drilling Highlights:

Hole PCH-DDH-002: 150 meters averaging 2.94% TREO, 0.12% Nb₂O₅, and 2.76% P₂O₅ from surface, including:

• 12 meters at 6.75% TREO, 0.21% Nb₂O₅, and 9.52% P₂O₅ from 37 meters
• 20 meters at 3.91% TREO, 0.13% Nb₂O₅, and 2.8% P₂O₅ from 81 meters
• 18 meters at 3.85% TREO, 0.14% Nb₂O₅, and 2.29% P₂O₅ from 132 meters

Hole PCH-DDH-003: 147.7 meters averaging 3.4% TREO, 0.18% Nb₂O₅, and 3.26% P₂O₅ from surface, including:

• 58 meters at 4.5% TREO, 0.26% Nb₂O₅, and 5.18% P₂O₅ from surface
• 17 meters at 2.94% TREO, 0.11% Nb₂O₅, and 1.44% P₂O₅ from 117 meters

Hole PCH-DDH-004: 153 meters averaging 3.06% TREO, 0.15% Nb₂O₅, and 2.31% P₂O₅ from surface, including:

• 10 meters at 4.99% TREO, 0.24% Nb₂O₅, and 3.22% P₂O₅ from 10 meters
• 9 meters at 5.12% TREO, 0.24% Nb₂O₅, and 7.37% P₂O₅ from 42 meters
• 18 meters at 4.1% TREO, 0.26% Nb₂O₅, and 3.15% P₂O₅ from 135 meters

Notably, all three drill holes ended in mineralization, suggesting potential extensions at depth and in multiple directions. Additionally, 97 out of 516 samples exhibited 'overlimit readings' for elements such as Lanthanum (La), Cerium (Ce), Praseodymium (Pr), Neodymium (Nd), and Niobium (Nb), indicating the possibility of even higher grades upon further analysis.

These findings underscore the significant potential of the Southwest Extension zone, suggesting that the PCH Project may host substantial high-grade carbonatitic-style rare earth mineralization, complementing its known Ionic Adsorption Clay (IAC) rare earth deposits. The company is planning an expansion and resource-definition drilling program, along with preliminary mineralogical and metallurgical testing on the diamond drill core.
