Wentworth Resources Limited : 2013 Full Year Results

• During the fourth quarter of 2013 commenced the acquisition of a combined 330 kilometers conventional and high resolution 2D seismic program.

Rovuma Onshore Block, Mozambique

• Completed the acquisition, processing and interpretation of 1,016 kilometers of onshore 2D seismic over the northern section of the Block.

• Commenced pre-drilling planning activities including the procurement of long lead items, site preparation and well planning in advance of the fully funded 2014 exploration drilling campaign.

Resource Assessment

• Results of an independent resource assessment by RPS Energy ("RPS") of the Company's Mozambique and Tanzania assets were announced during Q3 2013. Certain key extracts from RPS' Competent Person's Report ("CPR") follow and the complete updated CPR is available for download on the Company's website at www.wentworthresources.com:

(1) Stochastic aggregation assuming all prospects are successful. The probability of this occurring is the product of the individual GPoS of all prospects and is extremely small. The individual prospect GPoS estimates are included in the CPR.

RPS considers that the prospects' hydrocarbons are more likely to be gas than oil. However, there is some possibility that the Tembo prospect may contain oil (estimated by RPS to be about 30% - 40%), referred to above as "OIL CASE".

(1) Stochastic aggregation assuming all prospects are successful. The probability of this occurring is the product of the individual GPoS of all prospects and is extremely small. The individual prospect GPoS estimates are included in the CPR.
(2) Contingent resource estimates are for raw gas.

Outlook

• The construction of the Mtwara to Dar es Salaam pipeline is progressing well and the Company expects to begin selling natural gas into the pipeline in Q1 2015. The Company continues to work towards the signing of the GSA with the Tanzanian government.

• Processing and interpretation of this new seismic data during 2014 is expected to support future appraisal/development and exploration drilling which is anticipated to commence in Q4 2014 or Q1 2015.

• Drilling of two back-to-back exploration wells in the Rovuma Onshore License in Mozambique, with an optional third well. The first well is expected to spud in Q2 and take approximately 2 months to complete.

• The Company has the funds available to meet its currently planned capital commitments for the year 2014 including acquiring onshore 2D seismic in Tanzania, pre-drilling planning of one exploration or development well in Tanzania and two firm plus one optional exploration well in the Rovuma Onshore Block in Mozambique.

Geoff Bury, Managing Director, commented:

"We are pleased with the progress being made on thepipelineconnecting our gas fields in the Mtwara region of Tanzania to the capital Dar es Salaam. This pipeline will open up new markets for our natural gasand we look forward to it coming on-stream in Q1 2015.Following the successful equity financing concluded during Q4 2013, Wentworth has a solid balance sheet and is fully funded for our planned 2014 exploration activities. Exploration drilling in our Mozambique block is expected to commence in Q2 2014 and positive results could have a significant impact on the value of our assets. We look forward to updating shareholders on these exciting activities in due course."
