Phosphate Mining Goes Deep Sea

Phosphate Mining Goes Deep Sea [1]

With developing countries pushing for more resource-intensive foods, phosphate miners and fertilizer producers have begun to pursue deep sea phosphate reserves in a number of locations.

Deep sea and offshore mining are not new to the resource industry. Offshore oil [2] and gas [3] operations began in the 1890s and have become a cornerstone of the oil market. More recently, precious and base metals have moved offshore, with companies like Nautilus Minerals Inc. [4] (TSX:NUS [5],LSE:NUS,FWB:N9M) conducting gold and copper seabed explorations that borrow from the offshore oil [2] and gas industry.

While the world has long been aware of the existence of marine phosphates, which are typically found in the first 1,000 meters of the marine zone, few offshore projects have played much of a role in phosphate markets.

Currently, a number of projects are in operation. One of the most advanced is UCL Resources Ltd [6]’s (ASX:UCL [7],FWB:UNM) Sandpiper [8] marine phosphate project off the coast of Namibia. Operating its project approximately 40 to 60km off the coast in waters 180 to 300 meters deep, the project is fairly competitive, with an FOB cash operating cost of approximately US $57/ton, and production of 3MT/year of over 20 percent P₂O₅ phosphate rock on a 60 percent recovery ratio.

More recently, other developers are testing the limits of deep sea phosphate mining by going even deeper.

Digging deeper in New Zealand

New Zealand is leading the charge in marine phosphate exploration, with mining hopeful Chatham Rock Phosphate Ltd. [9] (NZAX:CRP [10]) recently reporting [11] that it has secured funding for its 2012 work program, which is to focus on continued exploration and environmental impact data collection.

US investment group Subsea Investments II announced that it has bought 11.4 million shares of Chatham for US $0.20 apiece to raise $2.28 million, as well as another 11.4 million unlisted three-year options for exercise on a one-for-one basis at $0.30 per share.

With its attention focused on Chatham Rise, a portion of seabed on the east coast of New Zealand’s South Island, Chatham project manager Chris Castle believes [12] underwater mining could begin as early as 2013.

Current scenarios assume [13] production levels of 1 to 1.5 million/t annually from the 4,726 square km permit site, with a total estimated local resource of 25 million tonnes of 20 to 24 percent P₂O₅ rock phosphate. The resource could produce enough phosphate for New Zealand for up to 30 years.

While New Zealand seems an unlikely place to begin mining deep sea phosphate, its phosphate fertilizer market currently relies on Moroccan phosphate imports to supply nearly all of the one million tonnes of phosphate the country requires each year.

The distance between the two countries is just under 20,000 km, and reducing transport costs could open the doors for a wide range of projects in the South Pacific region. Although it is still too early to provide any firm numbers, one company stated it believes it could mine for between US $90 and $120 per tonne. Currently, the cost of freight alone from Morocco stands around US $70 a tonne.

Manageable risks

But a number of risks are inherent to the project. Seabed mining presents higher risks than onshore mining due in great part to the absence of control over the work environment. This is especially true since Chatham is exploring a section 400 meters below the Pacific Ocean. That depth makes the project the world’s deepest phosphate mining project.

Outside of technical risks, the company still has to overcome barriers to raising cash overseas and selling the government on a relatively untested phosphate mining process in the middle of the country’s most important fishing grounds.

However, despite these concerns Castle believes the risks “appear manageable” thanks in part to the use of well-established seabed mining technology and the help of a variety of environmental and marine consultants who will advise on how best to reduce any environmental risks.

Those environmental risks will likely become more clear this year as Chatham spends up to US $10 million on environmental, geotechnical, and other projects as it moves towards its mining licence application and a pending environmental impact assessment.
