The sand mixture typically contains 5 to 40% magnetite. New Zealand had limited deposits of iron ore, but the deposits of ironsand were massive. It had been used by some early settlers to manufacture steel and pig iron, but the material could not be smelted in common bloomeries or blast furnaces.

The company has narrowed that down to two exploration areas covering 220 square kilometres of ironsand as well as 120 square kilometres of ilmenite off Waihi Beach. An exploration permit is the next step towards full-scale mining and allows for bulk sampling, drilling and mine feasibility studies.

A lot of the damaging sand mining in New Zealand, however, was a thing of the past, Dahm said. "Generally in New Zealand, we became aware of the issues of sand mining in the 60s and 70s.

Seabed mining is an experimental industrial field, which involves extracting submerged minerals and resources from the sea floor, either by dredging sand or lifting material in any other manner. Globally and in New Zealand, sand has been the primary target; primarily for use in construction but recently, for replenishment of urban beaches.
