Appia has unveiled an exceptional mineralization zone within and surrounding Target IV. The project showcases an impressive total weighted average within Target IV of 2,287 ppm or 0.23% (TREO) at an average depth of the mineralized zones to over 13 metres across the first 57 of 147 Reverse Circulation (RC) drill holes assayed and reported to date. 542 ppm or 0.054% Magnet Rare Earth Oxides (MREO) and 167 ppm or 0.017% Heavy Rare Earth Oxides (HREO). Target IV consists of 193.28 hectares of the total 40,963-hectare project. This exciting discovery expands upon the existing area of target IV, which is contained within one of the ten claims that make up the PCH project. The promise of this high-grade find continues to grow as the mineralization reaches even deeper into the Earth’s crust, promising a bright future for our exploration efforts.

In a groundbreaking development at the PCH Ionic Clay Project in Brazil, Appia has unveiled extraordinary assay drill results. These findings represent a major milestone in the exploration of rare earth elements (REE), as they showcase a remarkable 24-meter mineralization zone averaging a significant 38,655 ppm or 3.87% Total Rare Earth Oxides (TREO) starting from the surface on drill hole PCH-RC-063. Of particular significance is the high-grade 2 metre (m) intercept from 10m to 12m, showing an exceptional 92,758 ppm (Parts Per Million) or 9.28% TREO, with 13,798 ppm or 1.38% MREO, and 2,241 ppm or 0.22% Heavy Rare Earth Oxide (HREO), and 90,516 ppm or 9.05% Light Rare Earth Oxide (LREO).
These findings indicate the presence of 38,655 parts per million (ppm) or 3.87% TREO over the entire 24-meter depth of the drilling. The exceptional nature of this discovery is further highlighted by the inclusion of 6,869 ppm or 0.69% Magnet Rare Earth Oxides (MREO), 1,380 ppm or 0.14% Heavy Rare Earths Oxides (HREO), and 37,275 ppm or 3.28% Light Rare Earth Oxides (LREO). Remarkably, this high-grade mineralization extends from the surface and remains open at depth, emphasizing its significant potential for further mineralization.
The project hosts heavy rare earths + Yttrium (HREE +Y), boasting maximum values of 1,624 ppm and impressive averages of 167 ppm. Terbium (Tb) takes the spotlight with an average of 3.87 ppm and a peak at 58.83, while dysprosium (Dy) exhibits an average of 20.25 ppm and a remarkable high of 286.29 ppm in auger samples. The project also hosts light rare earths (LREE) boasting values of 15,024 ppm (1.54%) and an average of 1,145 ppm. Neodymium (Nd) and praseodymium (Pr), the main magnetic light rare earths, present respective maximum values of 3,131 ppm (Nd) and 885 ppm (Pr), alongside averages of 216 ppm (Nd) and 61.7 ppm (Pr). The HREE/LREE ratio in auger samples tells an intriguing tale, reaching a maximum of 39.5% and maintaining an average value of 16.67%.
The PCH wealth of resources includes several sought after elements including: Terbium (Tb), Dysprosium (Dy), Neodymium (Nd), and Praseodymium (Pr).
Appia has solidified its commitment through an earn-in agreement, aiming to acquire up to 70% interest by 2028.
After undergoing rigorous due diligence, overseen by geology expert Don Hains, the Brazilian team identified the ideal partnership in Appia. On March 7, 2023, Appia formalized its commitment by signing an earn-in agreement to acquire up to a 70% interest in our promising prospect. The Cachoeirinha Project spans an impressive 40,963 hectares and is strategically located within the Tocantins Structural Province in the Brasilia Fold Belt, situated in the Goiás State of Brazil.
The PCH Ionic Adsorption Clay REE project boasts 22 claims over a total area of 40,963.18 hectares, strategically located within a prime mineralization zone.
Situated in Brazil’s Tocantins Structural Province within the Brasilia Fold Belt (BFB), the PCH Ionic Clay Project presents a prime opportunity for geological exploration. This region is known for its Proterozoic terranes, formed during the Neoproterozoic era when the Amazon and São Francisco cratons collided.
The Tocantins Province’s geology is shaped by the interplay of the Brazilian/Pan-African cratons, resulting in a mix of mobile folding belts featuring volcanic-sedimentary rocks, granitic intrusions, and basic-ultrabasic formations. This region houses the Brasilia, Araguaia, and Paraguay ranges, each displaying unique geological orientations.
The eastern part of the Tocantins Province lies within the BFB, a gracefully arched folded belt that extends from north to south. It overlays the western margin of the São Francisco Craton, resting upon a basement of Paleoproterozoic granitic-gneissic terrane marked by Mesoproterozoic deformation.
Notably, the BFB hosts both the Serra Verde rare earth project in the north and the Araxa rare earth deposit in the south. These distinctive geological features paint the canvas of our PCH Ionic Clay Project, where valuable resources await exploration.
The unique geological landscape of the PCH property is marked by the presence of alkaline and alkaline-carbonatitic complexes. These geological formations are renowned as potential multi-commodity mineralized zones and are recognized as primary sources of rare earth elements and niobium. In Brazil, similar complexes have been successfully tapped for niobium and phosphate, while also revealing the tantalizing potential for rare earths with ionic clay development.
To best comprehend the local geology of our property, it’s essential to delve into the main lithostratigraphic units that define our landscape:
Each of these units contributes to the intricate geological tapestry that underscores the wealth of resources and opportunities awaiting exploration and development on the property.
Appia’s due diligence program yielded promising results, with 110 duplicate samples from twin auger holes across Target IV, along with samples from trenches and diamond drill holes, all producing assay data that matched the original results. These findings were confirmed by conducting the assays at the ISO 17025 registered SGS Geosol laboratory in Brazil, using the same methods as the original samples and certified standards from OREAS.
Appia has embarked on an ambitious exploration program, which included a high-resolution topographic survey of the Eastern claim blocks and a reverse circulation (RC) drill program involving approximately 300 holes spaced at 100m x 100m intervals, totalling 4,500 metres on Target IV. Additional auger drilling will further expand the rare earth potential to the west of Target IV.
Target IV comprises 193.28 hectares of claim number 860058/2018, which spans a total area of 1,874.6 hectares.
The property shows immense exploration potential, particularly in the western and eastern areas, with high radiometric values indicating unexplored rare earth mineralization potential. Appia’s exploration team has already achieved substantial progress completing 232 drill holes. Consisting of 147 Reverse Circulation holes, 84 Auger drill holes and 243.50 metres of Diamond drilling, reaching a combined depth of 2,847.5 metres to date.
Furthermore, an extensive airborne LiDAR survey, covering 1,702.50 hectares, has produced a highly detailed topographic map that will assist in pinpointing exploration targets. The data collected during this work campaign will be used to develop an initial Mineral Resource Estimate (MRE) for Target IV. Appia also plans to delve into initial metallurgy and mineralogy to assess the feasibility of traditional separation processes in this unique environment.
Notably, the Phase 1 RC drilling program has delivered outstanding results, with the first 67 holes averaging over 19 metres in depth and exhibiting remarkable high-grade mineralization. Some holes, like PCH-RC-001, PCH-RC-002, PCH-RC-008, PCH-RC-009, PCH-RC-011, PCH-RC-051, and PCH-RC-063 have even surpassed known mineralized zones in terms of Total Rare Earth Oxides (TREO), Magnet Rare Earth Oxides (MREO), and Heavy Rare Earth Oxides (HREO) values, confirming the significant potential of the project. These findings highlight the exciting prospects for Appia’s ongoing exploration efforts and the potential for substantial rare earth mineralization in the region.
