Zirconium and hafnium are contained in zircon at a ratio of about 50 to 1. Zircon is a coproduct or byproduct of the mining and processing of heavy-mineral sands for the titanium minerals, ilmenite and rutile, or tin minerals. The major end uses of zircon are refractories, foundry sands (including investment casting), and ceramic opacification.

Heavy surface mineralisation occurs in the sand units near Namalope flats and Tupuito high dune areas. The HM sand deposits occur in a sequence of fine to medium grained and silty sands consociated with clay units. The mineralisation constitutes about 85% of ilmenite, 5% of zircon and 2% of rutile, with minute variations among the units.
