Notes to Editor:

Sirius  Exploration  Plc  is  focused on commercialising properties that sit over  known  salt  and  potash
deposits  through  a combination of mining and developing energy and CO2 storage related projects  for  its
properties.   The  Company's operations include interests in properties that overlie significant  salt  and
potash deposits in North American and Australia.

To  this  end, Sirius has acquired the Intellectual Property and the issued share capital of three research
and  development  companies focused on innovative new technologies for developing its properties  post  the
mining  phase.   These technologies cover storing CO2 in the salt caverns created through solution  mining,
approaches  for  safely sequestering CO2 in underground salt beds, and the development  of  new  CO2  based
Compressed Air Energy Storage facilities for generating electricity.

Sirius  also continues, for the time being, to maintain its historic copper and gold interests in Macedonia
and iron ore interest in China via its equity position in a CIC Mining Resources Ltd vehicle.

Incorporated  in  October  2003 as a private company, Sirius Exploration subsequently  re-registered  as  a
public  company on 22 March 2005 when it was admitted to AIM. The Company's shares are additionally  traded
in North America as American Depository Receipts "ADR's" on OTCQX, the premier tier of the U.S.OTC market.
