Name(s) in local language(s): Mina La Juli, Rodeo de Los Molles, Provincia de San Luis, Argentina
This site was discovered as a result of air radimetrics anomalies detected in the area by CNEA. There is a mineralization of rare earths and thorium, which identified allanite, britholite, bastnäsite, and cerianite. The britholite-(Ce), brown, appears in compact nuclei reaching measure 8 cm. shown together with allanite-(Ce) and both are partial to completely replaced by bastnäsite-(Ce) or thorbastnäsite. It was characterized through analysis by diffraction X and electron microprobe.
