Nautilus Minerals Inc.: Solwara 1 Development Project Update

TORONTO, ONTARIO--(Marketwire - May 19, 2009) - Nautilus Minerals Inc. (TSX:NUS)(AIM:NUS) (the "Company" or "Nautilus") continues to make significant progress on the development of the Solwara 1 Project in the territorial waters of Papua New Guinea ("PNG") and is pleased to provide the following update.

- Cost reduction and optimisation work progresses

- In parallel, engineering and permitting activities continue

- Operating costs for the offshore production system expected to be in the range 50 - 65 US$/t

- Significant choice exists and lower costs available in today's vessel market

- In discussion with several prospective partners about joining in the Solwara 1 Development

Nautilus' CEO Stephen Rogers commented: "Significant progress has been made in the last quarter as we seek to maximise the opportunities in the current market. We are excited about the vessel options that are available. The project has been markedly enhanced as a result of the cost reduction and optimisation work completed in the last four months and this work continues. In parallel, we have had productive discussions with a number of parties that are interested in participating in Solwara 1 development."

Over the last four months, Nautilus has undertaken a commercial review of its Solwara 1 Project to identify potential capital and operating cost savings presented as a result of the current global financial downturn. Furthermore it is progressing, in parallel with engineering design and vessel sourcing, an optimisation program to identify technical improvements to the system which could realise further cost benefits. Significant advances have been made on vessel sourcing and system optimisation.

During this same period, Nautilus has been in discussions with several prospective partners regarding the development of the Bismarck Sea which includes Solwara 1.

Whilst the Solwara 1 cost reduction and optimisation program is ongoing, highlights of the work completed to date are:

- Shipping market enquiries have outlined a number of Mining Support Vessel ("MSV") options that offer significant savings and technical benefits to the project. Vessel evaluations and discussions are progressing with the aim of identifying a short list at the end of Q2 2009;

- In parallel with the vessel enquiry, a more detailed mooring analysis is in progress to further examine the viability of utilising a single pre-set deepwater mooring spread to maintain the MSV on station. Now that the traverse requirements of the Seafloor Mining Tool ("SMT") and the behaviours of the riser system are better understood, a moored vessel may offer benefits over a dynamically positioned vessel;

- Technip Inc. has been commissioned to undertake riser optimisation and cost saving analysis. This work will examine riser sizing and equipment sourcing to take advantage of the significant drop in global steel prices. This study is expected to report in Q3 of 2009 albeit savings have already been identified in the work completed to date;

- A trial and testing program is in place with Soil Machine Dynamics to proceed with planned quarry and submerged trials of key cutting and gathering components of the SMT, providing valuable operational input to the final design; and

- Discussions are in progress with GE Hydril to finalise a wear testing program on the Subsea Slurry Lift Pump to better plan maintenance and sparing regimes.

Overall subsea system engineering is currently about 80% complete.

Permitting has progressed with the Mining Lease Wardens Hearing completed ( An independent review of the Environmental Impact Statement commissioned by the PNG Government is nearing completion.

Market engagement with copper concentrate offtake parties has confirmed a strong interest in Solwara 1 copper concentrate as determined by the metallurgical test program supervised by Minerallurgy Ltd. and completed by Ammtec Laboratories in Perth, Western Australia.

Operating Costs

Operating costs for the offshore production system are expected to be in the range 50 - 65 US$ / dry ton of ore to extract and deliver material into a stockpile at the Port of Rabaul. This is based on a targeted production rate of between 1.2 - 1.6 million tonnes per annum. Fuel is 10% of this cost based on an oil price of US$60 per barrel assuming that a dynamically positioned vessel is finally selected by Nautilus in preference to the pre-set deepwater mooring spread discussed in 'work highlights' above.

The operating cost guidance is not an economic evaluation or an economic analysis. The current estimate of indicated and inferred mineral resources (870,000 tonnes of indicated mineral resources with 6.8% copper, 4.8 grams per tonne gold, 23 grams per tonne silver and 0.4% zinc and 1,300,000 tonnes of inferred mineral resources with 7.5% copper, 7.2 grams per tonne gold, 37 grams per tonne silver and 0.8% zinc using a 4% copper cut-off grade) does not support a mine life which demonstrates at this time that mining is economically viable. For more information concerning the Company's current mineral resource estimate, please refer to the Company's current Annual Information Form for the year ended December 31, 2008, which can be found under the Company's SEDAR profile at
