Update re Tapi Aike Seismic and Fracción C

Echo Energy plc, the Latin American focused upstream oil and gas company, is pleased to announce the safe and efficient completion of the 3D survey on schedule across the eastern cube on Tapi Aike. Initial indications suggest very good data quality. The equipment will now mobilise to the western cube and start acquisition once all equipment is on site and surveys have been completed.  The eastern cube (Chiripa Oeste) covers 414 sq km and the western cube (Travesia de Arriba) covers 790 sq km and will underpin the Tapi Aike drilling campaign.

The Company also confirms that it is currently utilising the results of mechanical stimulation at the EMS-1001 well at the Company's Fracción C licence, onshore Argentina, to refine a mechanical stimulation design for the ELM-1004 well. This refined stimulation design, once complete, will be considered in the light of the reservoir characteristics at the location and enable a final decision to be taken on whether to proceed with the stimulation.
