Geoff Bury, Wentworth Managing Director, commented: “We are very pleased that we now have reserves associated with our Mnazi Bay concession. This is a further step towards bringing our gas on stream and follows on the heels of the signing of our gas sales agreement (GSA) last year, and the ongoing implementation of the field infrastructure.”

Wentworth indicates to have a gas sales agreement in place and the facilities required to produce these reserves are nearing completion.
