Wentworth Resources Limited : Operational Update

PRESS RELEASE
22 June 2016

WENTWORTH RESOURCES LIMITED
("Wentworth" or "the Company")

Operational Update

Wentworth, the Oslo Stock Exchange (OSE: WRL) and AIM (AIM: WRL) listed independent, East Africa-focused oil & gas company, is pleased to provide an operational update on its appraisal asset in northern Mozambique and its producing gas asset in Mnazi Bay, Tanzania; ahead of the Company's Annual General Meeting to be held later this morning in London.

Mozambique - Operatorship and appraisal plan approved by Government

Further to the gas discovery made at the Tembo-1 well location in December 2014, Wentworth is pleased to report that Government approval by the Ministerio dos Reuros Minerais e Energia (Minister of Minerals & Energy) for an Appraisal Plan has now been received. Under the two-year appraisal period, Wentworth becomes the Operator of the Rovuma Onshore Concession ("Concession") and increases its participation interest in the Concession from 11.59% to 85%. State owned Empresa Nacional de Hidrocarbonetos ("ENH") retains a 15% participation interest as a carried partner through to the commencement of commercial operations. In addition, ENH has the right to acquire a further 15% participation interest in the Concession from Wentworth within 18 months from the date of submission for a development plan for consideration equal to the proportionate share of past costs incurred.

Implementation of a work program will commence in 2016 with the reprocessing of approximately 1,000 km of existing seismic data, the cost of which will be funded from internally generated cash flow.  Commencing the second half 2017, the Company plans to acquire a minimum of 500 km of new onshore 2D seismic data.  The drilling of an appraisal well is anticipated to occur in 2018 after the identification of a suitable drilling location based on the evaluation and integration of the new and existing seismic data. 

The Tembo-1 well was drilled to a total depth of 4,553 metres into rocks of Upper Jurassic age. Natural Gas and some condensate was recovered by modular formation dynamics testing ("MDT") confirming the petro physical analysis of 11 meters of pay in sands of Cretaceous age.  Tembo-1 was a milestone well for the Rovuma basin and an extensive amount of pertinent geologic data was collected which will have a significant impact on future exploration efforts in the basin. Further analysis of the geologic and petro physical data has led to the identification of additional zones of potential bypassed pay. These zones and the tested gas bearing sands will be subject to further evaluation with additional seismic and drilling. The agreed appraisal area, located around the Tembo-1 discovery onshore, measures approximately 2,500 km² providing the necessary running room to develop this potentially world class play fairway.

Tanzania - Production volumes continue to ramp up but have plateaued following impact of seasonal hydro-power generation and Symbion electrical power generation suspension

In Mnazi Bay, Tanzania, gas deliveries continue to the new transnational pipeline and are ultimately used in power generation facilities near Tanzania's commercial capital, Dar es Salaam. Production volumes from the Mnazi Bay gas field have been ramping up and peaked at 74 MMscf/d during Q2. However, volumes were curtailed for a period of time during April 2016 due to heavy rains when some natural gas power generation was displaced by hydro generated power. Furthermore, sales volume to the pipeline have been maintained at 50 MMscf/d since 2 June 2016 due to a dispute between Symbion, one of the power plants which utilises Mnazi Bay gas which has temporarily ceased operations, and TANESCO. It is unclear how long it will be before the dispute is resolved and power generation at the Symbion power plant resumes and, until such time, volumes are expected to remain at this level. Daily production volumes of 70 - 80 MMscf/d are still expected to be achieved in 2016, once this dispute has been resolved and power demand stabilizes.

As stated previously, payments to the Joint Venture for monthly gas sales delivered to the new pipeline by Tanzania Petroleum Development Corporation ("TPDC"), have been regularly received. 

Bob McBean, Executive Chairman, commented:

"I am very pleased to announce the receipt of Government approval for our operatorship and appraisal plan over the Tembo-1 gas discovery in Mozambique. With all the data gained to date through our exploration drilling and seismic interpretation, we believe this area of onshore Mozambique to be highly prospective and although we expect minimal capital spend this year, I am looking forward to working with ENH as we progress this acreage position toward appraisal drilling in the future.

"We continue to be extremely pleased with the performance of our wells in Mnazi Bay and how the new pipeline system is successfully delivering natural gas to Dar es Salaam. Whilst production volumes are lower than expected for the second quarter, this is considered short term in nature and the capacity to step up our production volumes remains in place. With further power generation capacity still being installed, we are confident of the long term growth prospects for Wentworth."
