Chatham Rock Phosphate Chatham Islands April 03
Who we are Chatham Rock Phosphate Golden Bay co started by us 006 Chris Castle - CEO Linda Sanders Comms director Toko Kapea and Adrian Wilson stakeholder relations (Tuia Group)
Why we are here Describe plans for out on the Rise Listen to your views and ideas, as the people most relevant to our plans Better understand how we can involve you in the project Assist you with the completion of a Cultural Impact Assessment document
The Project CRP has NZ s only major rock phosphate deposit (5m tonnes) m tonnes a year imported annually to NZ - mostly from Morocco Value of deposit is ~ $6 billion
Exploration permit offshore NZ
Formed 7-m years ago by current action on limestone seabed Nodules -50mm in m layer of sandy silt Nodules form 5% of seabed layer volume
Exploration history Extensive exploration 95-98 Significant spending by various parties (incl. NZ/German Govts, Fletcher Challenge) Suspended due to much lower phosphate prices, immature mining technology

Boskalis approach Jet pump, nozzle, suction mouth and suction pump Sliding mining head can be dragged, trailed or towed
Boskalis design Tow line Riser pipe Sediment return pipe Suction head
On board process Nodule separation on board using vibrating screens Redeposit fine material <mm Grade larger rock Full vessel returns to port & discharges cargo
Issues raised this week Effect of mining on environment (including plume/turbidity) Effect on fishing Port options What s in it for Chathams
Results from research 4 cruises Dec 0, Feb, March, April 0 Reports now being finalised Mapped shape and character of sea floor Better understand distribution of phosphate Will guide mining technology & strategy Will assist environmental planning Will increase public good science
Plume modelling Extensive modelling by experts Deltares Looked at different scenarios Sandy silt falls to seabed near where removed Plume - temporary and localised Settles within a couple of days and mostly within - km. Very fine elsewhere NIWA looking at any effects on sea life
0 NIWA reports Oceanographic data review, simulations of plume behaviour, models for sediment disposal estimates, impacts of sediment, effects on fish eggs Benthic communities, benthic and commercial fishing data, benthic fauna, habitat Marine mammals, seabirds, recolonisation, trophic level, substrate characterisation Other expert reports as well - 00 pages

Fishing impact 00 km from Chathams Not near fishing grounds NIWA says migrating rock lobster from NZ travel further north and at shallow depths - report Highly unlikely to be near potential plume areas Eel migration raised will look at that
Port Selection Process All-weather 0-4m deep port, berths for 50m vessels - available by Dec 04 Ocean Bay an outside chance, Waitangi not deep enough Capital cost of new port is very substantial, would need government funding
Benefits for Chatham Islands Nothing possible without permits Support services (rescue, monitoring, bunkering, provisioning, etc) based on Chathams if possible Local supply fertiliser on very good terms Support local causes, including scholarships Provide employment opportunities Biodiversity offsets (forestry, crops) other ideas
Any potential risks? Nothing nasty in the nodules or sand No chemical in on-board separation No processing on-shore Biosecurity follow protocols Phosphate if used on Chathams has minimal run-off
Environmental benefits Very low in cadmium cf Moroccan Lower carbon footprint through reduced transport Less run-off than superphosphate when applied directly - MPI endorsement Research contributes to public good knowledge
Benefits for NZ Import substitution $00m Exports $00m Will generate $900m in economic wealth - (NZIER study) New industry with skilled technical & support jobs Specialist expertise developed may result in similar NZ-led projects overseas
Market benefits Secure local supply of phosphate (rather than potentially politically unstable countries) Reduced foreign exchange risk and commodity price risk Cheaper source than Morocco
Technology partner Royal Boskalis Selected contractor for dredge design Provides services globally for dredging, earthmoving, maritime infrastructure 00 vessels, 5,600 employees, 75 countries CRP project will increase Boskalis order book by 5%
Royal Boskalis investment 0% shareholding & board seat Project under microscope for 8 months - sales, environmental & permitting See technical challenges as manageable A world first contract dredging companies don t invest in marine mining Stunning third party endorsement
