Dear Shareholder,

I enclose the notice of meeting for our AGM. You have already been sent a copy of our audited accounts for 2007 and our interim results but if you have mislaid these they can be downloaded again from our website www.siriusexploration.com (Select Investor Relations, Sirius accounts).

As set out in my Chairman’s statement, during much of 2007 we pursued the acquisition of Njahili Resources. It was extremely disappointing that in the end this did not take place, due mainly to the conditions in the financial markets. Your board nonetheless remains committed to expanding your company. We have an extremely strong management team and, as previously announced, we are in discussions with other companies and reviewing other opportunities. Whilst there can be no guarantee that these will proceed, this nonetheless provides clear evidence of our determination to expand the company.

To this end we are asking you to approve an increase in the authorized capital of the company and to allow the directors to allot the increased capital both for the raising of finance and for the acquisition of further assets.

In addition we are asking you to approve two share option schemes. The first, an EMI (Executive Management Incentive) scheme, is a scheme which can be approved by the Inland Revenue. This scheme is available only to full time employees of the company and, if approved by the Revenue, carries certain tax benefits. We believe that this scheme will help us attract high caliber employees as our direct workforce expands as we work to bring prospects into production.

The second share option is a general scheme which carries no tax benefits. This enables is to provide options to incentivise consultants as well as overseas employees and thus, for example, to reward individuals or companies who bring us prospects or companies which we can acquire.

With both of the above schemes options can be granted subject to performance criteria. These would obviously be different according to the individual who is being incentivised and accordingly will be set by the company’s remuneration committee at the time the options are granted.

We are holding the AGM in central London at our lawyer’s offices to make it as easy as possible for shareholders to attend.

Thank you for your support and I hope to see you at the meeting.

Richard Poulden

Chairman
