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

Production Guidance and Operational Update

Wentworth (AIM: WEN), the AIM listed independent, East Africa-focused oil & gas company announces the following operational update.

Mnazi Bay Operations

Average production to 24 June 2019 was 65.6 MMscf/d, gross, impacted in Q2 2019 by increased hydro-electric supply during the rainy season. The wet season is now over and output from the hydro-electric power plants is starting to diminish.

As previously announced, the Company expects to see existing demand underpinned and set to increase over the second half of 2019, due to:

• Repairs to turbines at Ubungo II plant now complete;
• Ongoing power evacuation problems at the Kinyerezi power stations now resolved by completion of the K-1 transmission station in May 2019;
• Kinyerezi-1 and Kinyerezi-2 power stations are running at near full capacity and are expected to continue throughout H2 2019;
• Demand from the Dangote Cement plant (power and clinker needs) is expected to reach up to 20 MMscfd in H2 2019; and
• The new Kinyerezi-1 Extension TANESCO facility is expected to begin its commissioning phase starting Q4 2019, gradually bringing on-stream demand of up to 30 MMcf/d into 2020.

Production has additionally been impacted by additional gas supplied into the transnational pipeline from the SongoSongo field, following the signing of a new Gas Sales Agreement (“GSA”) with the government of Tanzania in May 2019 by Pan African Energy Tanzania Limited (“PAET”). PAET are currently supplying c.20 MMScf/d into the National Natural Gas Pipeline (“NNGP”) and the Company anticipates that this additional supply will continue throughout H2 2019.

As a result of the above, full year average daily Mnazi Bay production for 2019 is now expected to be in the range of 60 to 75 MMscf/d.

As previously announced and planned, routine workover and pressure monitoring will continue throughout H2 2019 in order to optimise the performance of the field.

Thanks to consistent monthly payments that continue to be received from both Tanzanian Petroleum Development Company (“TPDC”) and Tanzania Electric Supply Company Limited (“TANESCO”), the Company continues to deleverage its balance sheet and comfortably meet its debt obligations, which now stand at $5 million. The Company anticipates being debt free in Q1 2020 with a final debt repayment in January 2020; cash balance at 31 May 2019 was $10.6 million.

Eskil Jersing, CEO, commented:

“We have adjusted our 2019 production guidance to take into account the additional 20 MMscf/d supplied into the NNGP from the only other in-country supplier, due to a new GSA executed post our 11 January 2019 guidance. Demand outlook continues to be strong and the Mnazi Bay joint venture partners continue to be well placed to supply that demand into the later part of 2019 and beyond.

“Regular, timely receipt of invoices enables us to repay our existing term loan whilst building cash and benefiting from reduced corporate costs post the redomicile last year.

“Finally, I am pleased to say that our Mozambique country exit has been executed smoothly and with no liability exposure or any ongoing forward costs.”
