Appia Rare Earths & Uranium (CSE: API) (OTCQX: APAAF), a mineral exploration with multiple rare earths and uranium projects in mining-friendly jurisdictions, including Goiás State, Brazil and Saskatchewan and Ontario, Canada, took a “significant step in cementing itself among the upper tier of critical mineral explorers,” according to company President Stephen Burega, when it entered into a definitive agreement to acquire up to a 70% interest in the PCH Project (https://ibn.fm/cnyNm).

Located in the Tocantins Structural Province of the Brasilia Fold Belt, Goiás State, Brazil, the 17,551.07-hectare PCH Project is one of the few major ionic clay projects in the Western world and one of the relatively few ionic clay REE deposits found outside China. Ionic clays can be mined with low-cost open-pit mining technologies and processed using simple technologies, according to Burega (https://ibn.fm/ZX1UL), suggesting that the PCH Project will require low capital and operational expenditures.

The viability of the open pit mining system is supported by the fact that the project shows ionic clay development with elevated rare earth element (“REE”) values immediately below the surface and extending down to a depth of more than 15 meters, based on assay results obtained from the vendor of the high potential property (original assays).

Still, the company set out to confirm whether the original assay results represented the true composition and quality of the property, commencing a due diligence program in April this year. As part of the due diligence program, Appia completed 110 duplicate samples from twin augur holes staggered across Target 4 of the property and found comparable results to the original assays. The company also collected 17 samples from trenches and 76 samples from diamond drill holes, with the results comparable to the original results.

These initial results confirmed widespread REE mineralization in ionic clays deposited after weathering of alkaline granitic source rocks as well as in-situ REE enrichment linked to the area’s underlying granite complex and a carbonatite intrusion extending to depths of more than 100 meters (https://ibn.fm/5ak7t).

“Mineralization is widespread across the property, with the most advanced target being a 2 km wide zone in the southwestern corner of the tenements known as Target 4,” commented Don Hains, an expert in industrial minerals and a senior consulting geologist. “The exploration work by the vendor showed REE enrichment in the soils to depths of 8 to 26 m with the majority in the upper 8-10 meters. Total REE grades in numerous auger holes drilled at Target 4 ranged from 274 parts per million (“ppm”) to 16,648 ppm (1.66%), with an average of 1,291 ppm total REE and, importantly, the valuable rare earths used in magnet applications (Pr, Nd, Tb, and Dy) + Y accounted for approximately 14% of total rare earths, with a maximum of 28.4%.”

The initial results also showed that heavy REE (“HREE”) accounted for 13.93% of the total rare earths or 145 ppm. The company compared its results with data from the Serra Verde Project, a large ionic-clay REE deposit and mine currently at advanced stages of construction in the northern part of the Goiás State, noting that the PCH Project has a relatively higher content of HREE in the deposit than Serra Verde despite having lower total average REE values. “The Serra Verde project currently under construction in northern Goiás State has total average REE values of 2,138 ppm (0.2138%) but HREE values of only 155 ppm, or 7.26% of total rare earths,” explained Hains.

Encouraged, the company embarked on comprehensive exploration activities to uncover the potential of its highly promising deposit. So far, Appia’s exploration team has employed a strategic combination of cutting-edge LiDAR surveying, extensive auger sampling, and Reverse Circulation (“RC”) drilling. The company intends to use the data collected from these drill and survey programs to develop an initial mineral resource estimate (“MRE”) on Target 4 (https://ibn.fm/AxXI3).
