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 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 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 the OTC Pink Sheets market.
