[New Carbonatite-Type Mineralization Discovered at Brazil's PCH Rare Earth Mine] According to Mining.com, Appia Rare Earths & Uranium Corp. announced that drilling at its Cachoeirinha (PCH) project in Goiás, Brazil, has confirmed the presence of high-grade rare earth carbonate breccia ore bodies.
According to a report by Mining.com, Appia Rare Earths & Uranium Corp. announced that drilling at its Cachoeirinha (PCH) project in Goiás, Brazil, has confirmed the presence of high-grade rare earth carbonate breccia ore bodies.
Three diamond drill holes deployed in the brecciated carbonatite intrusion at the southwestern extension of Target IV encountered high-grade total rare earth oxides (TREO), niobium oxides (Nb2O5), and phosphorus oxides (P2O5).
Tom Drivas, the company's CEO, stated that the initial diamond drill hole results were unexpected and could rank among the 2nd, 3rd, and 4th top rare earth drilling results globally in 2024.
The main mineralization findings are as follows:
◎ PCH-DDH-002 Hole
Mineralization was encountered from the surface to a depth of 150 meters, with a TREO grade of 1.14%, Nb2O5 grade of 0.12%, and P2O5 grade of 2.76%.
- At 37 meters, a 12-meter interval showed a TREO grade of 2.54%, Nb2O5 grade of 0.21%, and P2O5 grade of 9.52%.
- At 81 meters, a 20-meter interval showed a TREO grade of 1.75%, Nb2O5 grade of 0.13%, and P2O5 grade of 2.8%.
- At 132 meters, an 18-meter interval showed a TREO grade of 2.03%, Nb2O5 grade of 0.14%, and P2O5 grade of 2.29%.
◎ PCH-DDH-003 Hole
Mineralization was encountered from the surface to a depth of 147.7 meters, with a TREO grade of 1.69%, Nb2O5 grade of 0.18%, and P2O5 grade of 3.26%.
- From the surface to a depth of 58 meters, a TREO grade of 2.19%, Nb2O5 grade of 0.26%, and P2O5 grade of 5.18% were observed.
- At 117 meters, a 17-meter interval showed a TREO grade of 1.87%, Nb2O5 grade of 0.11%, and P2O5 grade of 1.44%.
◎ PCH-DDH-004 Hole
Mineralization was encountered from the surface to a depth of 153 meters, with a TREO grade of 1.08%, Nb2O5 grade of 0.15%, and P2O5 grade of 2.31%.
- At 10 meters, a 10-meter interval showed a TREO grade of 2.16%, Nb2O5 grade of 0.24%, and P2O5 grade of 3.22%.
- At 42 meters, a 9-meter interval showed a TREO grade of 3.08%, Nb2O5 grade of 0.24%, and P2O5 grade of 7.37%.
- At 135 meters, an 18-meter interval showed a TREO grade of 1.01%, Nb2O5 grade of 0.26%, and P2O5 grade of 3.15%.
All three drill holes encountered high-grade rare earth mineralization from top to bottom, indicating significant potential in the southwestern extension zone. These results suggest that, in addition to ion-adsorption-type rare earth mineralization, the PCH project also hosts substantial high-grade carbonatite rare earth ore bodies.
The ore body remains unconstrained at depth, as well as in the northeastern, northwestern, and southwestern directions. The company is planning to expand drilling activities to increase the resource base and conduct preliminary metallurgical testing on diamond drill core samples.
