An appraisal licence (or "Location") was issued by the Tanzanian Government for the Ntorya gas discovery, as announced on 8 July, and has been formally gazetted. This 760km² licence will require the acquisition of additional seismic data, planned for later in 2013, prior to appraisal drilling.

Once appraisal is complete, a development plan will be prepared prior to negotiating a long-term development licence. The Ntorya-1 well, drilled in 2012, discovered a gross 25 metre sandstone interval to which an independent reserves assessment has attributed a gross discovered volume of 178 billion cubic feet (bcf) in place.

Aminex estimates this to represent a contingent recoverable resource of 134 bcf. The independent assessment further included unrisked potential of approximately 1 trillion cubic feet (tcf) of gas at Ntorya, which Aminex considers to represent a likely recovery of 750 bcf. The Ntorya-1 well flowed over 20 million cubic feet per day on a 1" choke (equivalent to over 3,000 barrels oil per day) and also produced 53 degree API condensate at a rate of 139 barrels per day, believed by the Company to be the largest volume of liquid hydrocarbons tested to date in the Ruvuma Basin, onshore or offshore.
