Nautilus Minerals Discovers Five High Grade Copper-Zinc Systems
TORONTO, ONTARIO--(Marketwire - Jan. 14, 2010) - Nautilus Minerals Inc. (TSX:NUS)(AIM:NUS) (the
"Company" or "Nautilus") is pleased to announce the discovery of five high grade Seafloor Massive
Sulphide ("SMS") systems, designated Solwara 12, 13, 14, 16, and 18, during its 2009 exploration
campaign. Copper grades up to 32.4% and zinc grades up to 52.6% were reported from grab samples
collected from these discoveries using a hand held x-ray fluorescence ("XRF") meter. Final assays on
samples collected from Solwara 12 and 13, have also been received, and indicate gold up to 39.7 g/t
and silver up to 682 g/t. Additionally, the company has made a further high grade discovery at Solwara
11 (11i) in the Western Bismarck Sea.
Stephen Rogers, Nautilus' CEO, commented: "Further success in the Bismarck Sea, PNG, combined with
good assay results clearly highlights this region as a significant SMS domain. Our work is now
focussed on the evaluation and ranking of the new systems in preparation for an intensive drilling
campaign in 2010."
The exploration vessel MV Fugro Solstice was successfully demobilised in Singapore on 12 January 2010
after completing a 132 day program of water geochemistry studies, geophysics, remotely operated
vehicle ("ROV") mapping and ROV sampling. A total of 18 SMS systems have now been defined within the
Bismarck Sea, along with numerous zones of hot water venting, smaller chimney fields, and barite-rich
zones.
Final assay results, including gold (Au) and silver (Ag), on samples collected from Solwara 12 and 13,
which were previously reported on 4 November 2009 (http://www.nautilusminerals.com/s/Media-
NewsReleases.asp?ReportID=370349) indicate high precious metal grades, which is consistent with other
SMS systems in the Bismarck Sea. Assays up to a maximum of 39.70 g/t Au and 682 g/t Ag were recorded
from the 10 sulphide samples collected at Solwara 12, and a maximum of 9.23 g/t Au and 1,550 g/t Ag
were recorded from the seven samples collected at Solwara 13.
A further two lower grade systems (Solwara 17 and 19) were also discovered in the Bismarck Sea and one
new system (Solwara 15) where samples were not taken due to an ROV breakdown. All three systems will
require further investigation. Nautilus considers the presence of hydrothermal mineralisation and
alteration at these sites encouraging, especially given that the two lower grade systems occur in the
older part of the Bismarck Sea. Additional exploration work is planned to test this potential.

Solwara 12 and 13:
Solwara 12 and 13 systems occur in the eastern Manus Basin, approximately 40 to 60km NNW of Solwara 1
(Figure 1). Preliminary XRF results were reported previously. Final assay results are shown in Tables
1 and 2 below, and highlight the high grade of the samples, particularly with regard to precious
metals.

Solwara 17:
Solwara 17 occurs within the older Willaumez Spreading Centre approximately 60km NE of Solwara 11. The
system comprises a 110m by 60m zone of "oxidized" outcropping sulphides and extensive algal mats and
hydrothermal oxide coatings in relatively shallow waters (around 450m). XRF analysis suggests the
samples collected from the system outcropping at surface are close to the detection limit of the
portable Niton XRF machine (Refer to Table 5).

Future Work
The 2009 exploration program generated a large parcel of geophysical and bathymetric data, as well as
rock samples and maps which will drive the next round of resource drilling and evaluation in the
Bismarck Sea. The results of this work will be reported in the Company's ongoing NI43-101 regulatory
filings as and when the finished products become available. Final assay results for base metals and
precious metals are pending for all samples other than those collected from Solwara 12 and 13.
Target Testing Procedure
Sulphide mineralisation at the various prospects was observed using a FCV3000 ROV during target
testing traverses. The planned traverses were generally a series of parallel lines, nominally 200 or
300 metres apart. When chimney structures are located, using a combination of video and sonar
apparatus, that area is mapped in greater detail with the ROV, and samples collected.
Sampling Procedure
Grab samples were collected from the seafloor using a manipulator arm mounted on the ROV. Chimney
samples averaging 37 kg (from 5 kg to 70 kg) were placed in a separate sample cage for recovery to the
ship. They were then processed on board. Sub-samples averaging 4.8 kg (from 1.6 kg to 7.3 kg) were
taken from each of the sulphide samples using a pneumatic jack hammer, generally taking a cross
section of the sample towards the base of the block. The remaining portions of each sample were
retained for reference purposes.
Equipment Spread
The mapping work described herein was completed using a Fugro FCV3000 series ROV. The ROV is equipped
with sensors used to map the seafloor. These include: various video cameras and two magnetometers
provided by Ocean Floor Geophysics Inc. In addition, high-resolution mapping sonars housed on the ROV
are being successfully used for the first time to identify real-time seafloor features ahead and to
the sides of the ROV beyond the range of the video camera systems used previously.
For seafloor sampling purposes, the ROV is equipped with two manipulator arms and a custom-built
sample tray, or "geobox", for storing up to 10 hand-sized grab samples or scoop samples. Larger
samples are stowed and recovered using a custom built array of salvage bins.
Laboratory Assaying
All laboratory analyses were carried out by ALS Laboratory Group in Brisbane and Townsville,
Australia. ALS operates quality systems based on international standards ISO/IEC17025:1999 "General
Requirements for the Competence of Calibration and Testing Laboratories" and ISO9001:2000 "Quality
Management Systems - Requirements".
Sample Custodianship
All sampling, sample handling and analysis was completed under the supervision of Nautilus personnel.
Sampling was carried out aboard the MV Fugro Solstice while at sea. All sub-samples were placed into
numbered plastic bags. The bagged samples were then subsequently placed into sealed plastic containers
with security tags, and transported to ALS laboratories in Townsville, Australia, via courier.
Quality Assurance
Low-grade blank material, field-duplicates and externally certified geochemical reference materials
with known concentrations of gold, copper, zinc, lead and silver were included for analysis with each
batch of samples as per a documented quality assurance/quality control procedure. Analysis of these
reference materials indicates that the quality of sample preparation and analyses are within
acceptable limits for the reporting exploration results.
(i) Note on results of indicative analyses from hand-held XRF, Niton XLT 592 instrument
A hand-held XRF instrument (Niton XLT 592) was used to obtain indications of the grade of materials
recovered from the seafloor. It does not provide the accuracy required to report assays. The
instrument is not calibrated using certified standards and the samples have not been crushed and
prepared to minimise matrix effects, which may affect the accuracy of the analysis. However, a suite
of eight standard samples were analysed for copper, zinc, lead and iron prior to use on the MV Fugro
Solstice 2009 cruise. These results, together with past comparisons between the XRF analysis and assay
results for similar samples, indicate the XRF tool is a reliable method for providing indicative
results of the tenor of mineralisation, and provides valuable data for "real time" decision-making.
The Nitron XLT 592 analyser is used by Nautilus in a setting designed for sulphide-rich samples
containing high metal contents greater than 1%. Results have low precision and accuracy in samples
with metal contents less than 1%.
Measurements by the hand-held XRF instrument are not assay results and do not measure gold or silver.
Samples will be formally assayed by an ALS Group laboratory.
