PotlatchDeltic(PCH) Newsfile·2025-01-22 12:30Core Viewpoint - Appia Rare Earths & Uranium Corp. announced exceptional results from its diamond drilling program at the PCH project in Goias, Brazil, confirming high-grade mineralization in the carbonatitic breccia zone [1][2]. Group 1: Drilling Results - The diamond drilling program included three drill holes that intercepted significant amounts of Total Rare Earth Oxide (TREO), Niobium Oxide (Nb2O5), and Phosphate Oxide (P2O5) [1]. - Drill hole PCH-DDH-002 reported 150 metres at 1.14% TREO, 0.12% Nb2O5, and 2.76% P2O5 from surface, with notable intervals of higher grades [3]. - Drill hole PCH-DDH-003 showed 147.7 metres at 1.69% TREO, 0.18% Nb2O5, and 3.26% P2O5 from surface, including 58 metres at 2.19% TREO [3]. - Drill hole PCH-DDH-004 recorded 153 metres at 1.08% TREO, 0.15% Nb2O5, and 2.31% P2O5 from surface, with significant intervals of higher grades [3]. Group 2: Mineralization Potential - The results indicate that the PCH project may contain substantial high-grade carbonatitic style rare earths, in addition to Ionic Adsorption Clay (IAC) rare earth deposits [2]. - Mineralization is open at depth and in multiple directions (northeast, northwest, and southwest), suggesting potential for further resource expansion [7]. Group 3: Project Development Plans - The company is developing plans for an expansion/resource-definition drilling program and preliminary mineralogical-metallurgical test work on the diamond drill core [2]. - The favorable location of the PCH project provides easy access to road and power infrastructure, along with a supportive relationship with the local community [4]. Group 4: Quality Control and Analysis - The samples from the diamond drill holes were sent to ALS laboratory for analysis, ensuring rigorous quality control measures were implemented throughout the sampling and analytical processes [11][12]. - All analytical results have passed internal QA/QC review, confirming the reliability of the reported data [13].
