Wentworth Resources Limited : Tanzania Reserves Update

PRESS RELEASE
25 February 2016

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

Tanzania Reserves Update

Wentworth, the Oslo Stock Exchange (OSE: WRL) and AIM (AIM: WRL) listed independent, East Africa-focused oil & gas company, is pleased to announce the results of an independent evaluation of the gas reserves within the Mnazi Bay Concession in Tanzania, carried out by RPS Energy Canada Ltd. ("RPS"), Calgary, Canada on behalf of Maurel et Prom (Operator) and Wentworth Resources.

HIGHLIGHTS (net to Wentworth):

• Net Proved Developed Producing (PDP) reserves increased by 88%
• Net Proved + Probable (2P) reserves increased by 20%
• Net Proved + Probable (2P) reserves are valued at US$179.2 million after tax (NPV10)
• Proved (1P) - 107.4 Bscf gross (17.9 MMboe); 76.4 Bscf net (12.7 MMboe)
• Proved + Probable (2P) - 181.1 Bscf gross (30.2 MMboe); 114.5 Bscf net (19.1 MMboe)
• Proved, Probable & Possible (3P) - 275.3 Bscf gross (45.9 MMboe); 156.0 Bscf net (26.0 MMboe)

The significant 20% increase in 2P reserves from 31 December 2014, which results from favourable data from the MB-4 well drilled during 2015 and is detailed within the Reserves Report, further demonstrates the quality of the Company's assets in Tanzania. With Mnazi Bay gas assets now on-stream, and production from the existing gas fields increasing to meet the current gas demand, the existing reserves provide a solid foundation to grow production from the Mnazi Bay concession.

Geoff Bury, Managing Director, commented:

"We are delighted that our updated CPR with the enhanced attributable reserves has so conclusively underpinned the core value of Wentworth.  Production from Mnazi Bay continues to ramp up and we are greatly encouraged by the performance of our existing wells to date. Furthermore, in the current challenging climate within the oil and gas sector, we believe our core strategic focus on commercialising our gas in Tanzania is given further endorsement by the results of this report. "

Mnazi Bay, Tanzania Reserves:
