For immediate release: 11 January 2010

Sirius Exploration PLC

("Sirius" or the "Company")

Issue of Equity in connection with increasing stake in AusPotash Corporation

Further to the announcements made on 15 September, 22 September and 29 September 2009, Sirius (AIM: SXX, OTC:
SRUXY) announces that it has entered into an escrow agreement with three shareholders of Auspotash Corporation
and has, consequently, completed the acquisition today of a further 1,295,254 common shares of AusPotash
Corporation, representing 2.32 per cent of the issued and outstanding common shares of AusPotash (the
"Transaction"). The consideration for the Transaction is the issue of 2,590,508 new Sirius Ordinary Shares of
0.25p ("Ordinary Shares"). As a result of the Transaction, Sirius now has an interest of 71.15% of AusPotash.

The acquisition was contemplated in the amended and restated lock-up agreement executed with Auspotash on
September 29, 2009, which agreement permitted the acquisition of certain shares of Auspotash subject to the
resolution of certain Canadian tax matters. Such tax matters are being resolved by placing 25% of the issued
shares, being 647,627 Ordinary Shares, into escrow until such time as the vending shareholders have paid the
requisite Canadian tax. Once this has been done these Ordinary Shares will be released from escrow to the
AusPotash shareholders.

Further to this transaction 16,097,327 common shares of AusPotash remain to be purchased by Sirius and the
Company will notify the market when these are completed in due course.

Application has been made for the 2,590,508 new Ordinary Shares which will, when issued, rank pari passu with
the existing Ordinary Shares in issue, to be admitted to trading on AIM and trading, is expected to commence on
18 January 2010.

Following the issue of the new Ordinary Shares as set out above, the total number of shares in issue will be
628,118,678.
