Wentworth Posts Prospective Resoures at Mozambique Block

Wentworth announced an independent assessment of the Company's gross and net prospective resources for the Rovuma Onshore Block, Mozambique. The assessment was completed by RPS Energy Canada Ltd. and its associated geology and geophysics firm, Petrel Robertson Consulting Ltd. ("RPS"). RPS' assessment was derived from interpreting 2D seismic lines supplied by Wentworth and AVO analysis of two prospects. This is the first time in the Company's history that Prospective Resources have been assigned to this block.

Executive Chairman, Bob McBean, commented, "The third party endorsement of prospective resources is another step forward in proving up the potential of our Onshore Rovuma Block. We now look forward to the acquisition of new seismic data and the drilling of at least one exploration well as part of the current second exploration phase. We are pleased to announce RPS' findings to our stakeholders as this is the first independent assessment of this strategically important block."
