Echo Energy shot up by more than 10% in London this morning after its enlarged share capital was admitted to trading.
The London-based company also said its shareholders had approved the acquisitions of several onshore oil and gas assets in Argentina.
Shares were suspended last year following the announcement of a reverse takeover deal with Compania General de Combustibles SA to gain onshore oil and gas permits in Argentina.
Echo plans to acquire 50% stakes in the Fracción C, Fracción D and Laguna De Los Capones concessions and a 50% interest in the Tapi Aike exploration permit, which are all located onshore in Argentina.
Echo Energy is an upstream oil and gas company targeting South American exploration and production assets.
