Vaalkop (Afrikans for pale hill) Dam is situated approximately 90 km northwest of Pretoria, on farm Bulkop 75 JQ. The dam completed in 1972, was built 300 m downstream of the merging rivers Hex and Elands. The area is underlain by Nebo Granite of the Bushveld Lebowa Granite Suite.
Aggregates used in the dam wall building was excavated from a granite quarry approx 1.5 km from the dam on the west side of Elands river. Secondary minerals were found in miarolitic cavities within several granitic boulders from the quarry (Atanasova, M., Cairncross, B. and Windisch, W.R. (2016) Microminerals of the Bushveld Complex, South Africa).
