A manganese mine located in northern Cape Province.

The open pit operation exploits low-grade manganese ore, compared to the northerly located Wessels and N'Chwaning mines that exploit high-grade manganese ore.

It is the latter that accounts for most of the secondary, collector minerals, as opposed to the low-grade mineralization, hence the Mamatwan mine produces few secondary, aesthetic species.
