Nautilus Minerals Inc.: Proposed Cancellation of Admission of Common Shares to Trading on AIM

Nautilus Minerals Inc.: Proposed Cancellation of Admission of Common Shares to 
Trading on AIM 
TORONTO, ONTARIO -- (Marketwire) -- 02/01/13 -- Nautilus Minerals
Inc. (TSX:NUS)(OTCQX:NUSMF)(AIM:NUS) ("Company" or "Nautilus")
announces that the admission of its common shares to trading on the
AIM market of London Stock Exchange plc ("AIM") will be cancelled
with effect from 7:00 a.m on March 8, 2013 (GMT). The last trading
day on AIM will be March 7, 2013. The Company will continue to
maintain its listing on the Toronto Stock Exchange ("TSX").  
This decision to cancel has been made following a careful review of
Nautilus' listing on AIM by the board of directors of the Company
("Board"). The principal reasons for the Board's decision relate to
the lack of liquidity in the Company's shares on AIM and the cost of
maintaining the listing on AIM. The Board considers that the costs
incurred to maintain the listing of the Company's shares on AIM now
exceed current and potential future benefits the Company could obtain
from the listing. The Board looks forward to the continued support of
its shareholders though its TSX listing.  
Further information on cancellation of AIM listing and termination of
DI register  
Computershare Investors Services Plc, acting in its capacity as
Depositary in respect of Nautilus' Depositary Interests ("DI"), which
are the Company's securities listed on AIM, and each of which
represents one common share), will be writing to all DI holders today
to advise as to the process for the termination of DIs (see Links
section below to obtain a copy of the letter to DI Holders). The
termination of DIs is a separate event to the cancellation of the AIM
listing. All DIs will remain valid after the cancellation of the AIM
listing, up until the termination of the DI register.  
In accordance with the deed constituting the DIs, DI holders will be
given 90 days' notice from today of the termination of the DI
register ("Notice Period"). During the Notice Period, DI holders may
transfer their holding to the Canadian based depository ("Canadian
Depository") operated by the Canadian Depository for Securities
Limited ("CDS"). An updated holding statement of Nautilus shares will
then be issued to former DI holders. Once the shares are transferred
to the Canadian Depository, they will be tradable through the
facilities of the TSX. This process can be completed quickly if all
documents received are valid.   
To transfer your holding, DI holders should contact the global
transactions team for Computershare. Please e-mail
! or phone Suzanne
Schofield on +44 1534 281869. Beneficial shareholders who hold shares
with a UK Broker in CREST should contact their broker if they wish to
sell/transfer their shares.  
If shareholders wish to sell their DIs before the transfer to the
Canadian Depository, they must do so prior to the date of
termination. Once the Notice Period has expired, DI holders will
automatically be transferred to the UK Branch Certificated Share
Register in Jersey ("Jersey Register"). Subsequently, following the
termination of the Jersey Register, former DI holders and
certificated holders on the Jersey Branch Register will be
transferred to the Canadian Register and a certificate of holding
will be issued to the holder as recorded on the DI/Branch register.  
The Company will continue to maintain its listing on the TSX and, as
such, cancellation of the AIM listing is not conditional upon
shareholder consent.
