A phosphate pegmatite rich in secondary phosphates situated on Farm Sandamap North 115, just east of the Usakos-Uis road. It stands out in the surrounding landscape as a quartz capped hill with white quartz scree on the slopes. The farmstead is known locally as Sandamab & in some of the literature the pegmatite is also written as "Sandamab".
Initial mining started in the 1920s when cassiterite was mined & this mine was one of the first tin mines in the area. Mining was haphazard following the tin-rich areas & the mine changed hands many times. The last epoch of mining was mainly for petalite. There are large dilapidated excavations on the hill with dumps scattered over the hill slope. Mining ceased many years ago.
