The deposit is in a pegmatite that has been exposed by several open cuts on a prominent white ridge visible for miles from the adjacent countryside. Exploration of the deposit was performed by Dupas Metals Limited in the 1950's, by Utufora Mining Co.Ltd. in 1963, and by Moly Hill Mining Corporation Ltd. from 1964 to 1968. More recently (1990's) quartz has been quarried for use as flux in the smelter in Noranda.

Geochronology

Mineralization age: Precambrian : 2730 ± 34 Ma to 1607 ± 218 Ma

Important note: This table is based only on rock and mineral ages recorded below 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.
