A REE prospect, being developed by E-Tech Resources. The REEs are associated with Monazite-(Ce) which occurs as large crystals in dolomitic carbonatites. The carbonatites, having an average thickness of 1-2 m (max. 7 m), intrude parallel to the foliation of intensely folded Damaran schists and quartzites of the Etusis formation.

Geochronology
Mineralization age: Cambrian : 500 ± 20 MaImportant note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
