Precisely; the first mineral deposit in Mexico, in which the lanthanids were considered as of possible commercial interest, was the pegmatites of "Santa Ana" and "La Crisis", in the region of Telixtlahuaca, Oaxaca, where the minerals alanite and fergusonite were identified (Gonzalez, 1956).

The results to date have indicated that the light rare earths (LREE) in the Nechalacho deposit are contained in four minerals: allanite, monazite, bastnaesite and synchisite, and the heavy rare earths (HREE) are present in two minerals: fergusonite and zircon, the latter also being host to zirconium (Zr).
