    Ilmenite is another mineral that contains titanium and iron. Coastal ilmenite deposits are known from the South Island’s West Coast, with the two largest deposits at Barrytown and Greymouth comprising a total of around 12.4 million tonnes. This can be processed to produce high-purity rutile (titanium dioxide), which is used as a paint pigment

    The Barrytown heavymineral sandsare high grade, averaging around 10%ilmenite,and in many cases much more. This close up is a high grade sample from the horizon shown in the previous image. While there is gold associated with the heavymineral sands,there is also potential for a separate, much more interesting, gold occurrence, associated with glacial till on the eastern side of the Barrytown Flats
