For immediate release: 13 October 2009
SIRIUS EXPLORATION Plc
("Sirius" or "the Company")
Acquisition of Co2 technology patents
Sirius Exploration Plc, (AIM: SXX, OTC: SRUXY), the diversified mining and exploration holding company focused
on North America and Australia, announces that it has acquired 100% of the ordinary shares in and rights to
patent applications of Co2 Energy Storage Pty Ltd (Queensland), Bicarb Sequestration Pty and Co2 Energy Storage
Ltd (Nevada) USA (together "the Companies") for the issue of options granted by the Company over 2,550,000
Ordinary Shares which are exercisable at any time within the three years of issue at 17.5p per share. The
acquisition includes a patent application put in place by the Companies owner, Walter Doyle, relating to the
use of Co2 in energy storage.
Information on the Companies
The Companies are privately held in Queensland Australia and Nevada USA. The Companies have commenced initiatives
in two main areas:
1. Storage or sequestration of Co2
The Companies are currently working on a range of innovative approaches for both the storage of Co2 in salt
caverns, as created by solution mining, and the sequestration of Co2 - whereby Co2 is effectively rendered
inert - by directly injecting it into certain types of salt beds. This work is being undertaken with
various Universities and research organisations in Australia and the USA.
2. CAES revised to use Co2
The Companies are also working on an innovative new technology which takes the concept of CAES (Compressed
Air Energy Storage) and revises it to use compressed Co2 rather than compressed air. Part of the
acquisition includes a patent filed by Co2 Energy Storage Pty Ltd naming Walter Doyle as the inventor for
the concept of using sequestrated Co2 in a dual salt cavern model for the storage of electricity.
This not only provides greater power storage than conventional CAES but would also qualify for carbon credits
for the sequestrated Co2.
Reasons for the Acquisition
The transaction provides Sirius with a new technology which can be used to expand the economic benefits of
Sirius' salt deposits in Australia and North America.
The Directors of Sirius believe that Co2 sequestration and storage is going to be one of the most important
industries of the future. These acquisitions place Sirius firmly in the forefront of research in these
industries and provide an important expansion route for the use of Sirius' existing assets.
Background on Sirius
Sirius is quoted on the AIM market of the London Stock Exchange in London and its shares are also traded in
North America through the use of an ADR facility. Sirius currently has interests in potash and salt caverns
through its subsidiaries Dakota Salts LLC and Auspotash Limited.
Richard Poulden, the Chairman of Sirius, commented:
"By 2050 carbon emissions must be cut by half yet energy demands are likely to increase. Salt caverns and salt
beds offer the potential to provide a natural, and geologically sound, way for removing harmful carbon
emissions from the earth's atmosphere. The acquisition of this group of companies not only provides us with an
important technology base that will allow us potentially to extend significantly the commercial life-cycle of
our own salt and potash properties, it also provides us with a technology that potentially can be licensed to
third parties. We see this as a key strategic acquisition in the development of Sirius as a significant player
in the salt and potash market."
