PRESS RELEASE 9 March 2015

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

Tanzania Reserves Update

Wentworth, the Oslo Stock Exchange (OSE: WRL) and AIM (AIM: WRL) listed independent, East Africafocused 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.

This report marks a further significant shift in Wentworth's operational status, with independent reserves attributed to the Company's Mnazi Bay gas fields for the first time. Production in Tanzania is now imminent, as Wentworth has a gas sales agreement in place and the facilities required to produce these reserves are nearing completion.

HIGHLIGHTS:

• Wentworth's Proved + Probable (2P) reserves is valued at US\$152.9 million after tax (NPV10)
• Proved (1P) 89.2 Bscf gross (14.9 MMboe); 68.2 Bscf net (11.4 MMboe)
• Proved + Probable (2P) 141.5 Bscf gross (23.6 MMboe); 95.5 Bscf net (15.9 MMboe)
• Proved, Probable & Possible (3P) 226.6 Bscf gross (37.8 MMboe); 135.3 Bscf net (22.6 MMboe)

Geoff Bury, 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."

Bscf	Billion standard cubic feet
BOE or boe	Barrels of oil equivalent
Contingent Resources	Quantities of petroleum estimated, as at a given date, to be potentially
	recoverable from known accumulations, but the applied project(s) are not yet
	considered mature enough for commercial development due to one or more
	contingencies
GIIP	Gas Initially In Place
MMbbl	Million barrels
MMboe	Million barrels of oil equivalent
NPV	Net present value (at a specified discount rate and specified discount date)
PDP	Proved developed producing
Gross Reserves	Reserves volumes before deductions for royalty
Net Reserves	Reserves volumes after deduction of royalty
1P	Proved Reserves, those quantities of petroleum, which, by analysis of geoscience
	and engineering data, can be estimated with reasonable certainty to be
	commercially recoverable, from a given date forward, from known reservoirs
	and under defined economic conditions, operating methods, and government
	regulations.
2P	Proved + Probable Reserves, those additional Reserves which analysis of
	geoscience and engineering data indicate are less likely to be recovered than
	Proved Reserves but more certain to be recovered than Possible Reserves. It is
	equally likely that actual remaining quantities recovered will be greater than or
	less than the sum of the estimated Proved plus Probable Reserves
3P	Proved + Probable + Possible Reserves, those additional reserves which analysis
	of geoscience and engineering data suggest are less likely to be recoverable than
	Probable Reserves.
Prospective Resources	Petroleum deposits that are estimated, on a given date, to be potentially
