The total number of voting rights in the capital of the Company is now 273,940,493 ordinary shares.

Cathal Friel, Chairman of Fastnet, said:

"We are very pleased to have completed the £15m placing. We are now fully funded for all our work commitments up to 2015, across our acreage in Morocco with our partner Kosmos Energy and our portfolio in the Celtic Sea in Ireland.

"We now have the financial resources and busy work programme to drive value for our shareholders as we head into a busy 2013."
