About this dataset

The production statistics feature coal, industrial minerals and metallic minerals groups. Metallic minerals produced are gold, silver and titanomagnetite ironsand. Rock, sand, and aggregate are produced for roading and construction and are vital for the development of New Zealand’s infrastructure.
A number of other industrial rocks and minerals are produced for local and export markets. They include bentonite, various clays, diatomite, perlite, pumice, serpentine, silica and zeolite.
