Sydney – A decision to block a deep sea mining venture off the New Zealand coast has cast a shadow over an emerging global industry that proponents say could revolutionise how minerals are extracted.
The sea floor is rich in copper, nickel, manganese, cobalt, zinc and a host of other minerals used in technology products. Improvements in undersea extraction technology have now put these within reach of miners.
New Zealand has lead the way in developing sea floor mining. But progress has now stalled following this month’s rejection by environmental regulators of a proposed project by Chatham Rock Phosphate off the coast of Canterbury, the second mine application refused within a year.
The decisions were welcomed by green groups, who fret that mining would damage vulnerable undersea ecosystems, which are relatively underexplored. But their delight is not shared by companies eyeing deep sea prospects.
“To say we are bitterly disappointed is an understatement,” said Chris Castle, Chatham Rock Phosphate’s managing director. “This will make it even harder, if not impossible for companies to attract capital for new projects in New Zealand.”
For almost 20 years deep sea mining has been flagged as a commercial opportunity. David Cameron, UK prime minister, claims it could be worth £40bn to the UK over a 30-year period.
