North American Petroleum Plc/ Index: ISDX / Epic: NAPP / Sector: Oil & Gas 3 June 2013 North American Petroleum Plc (NAP or the Company) Participation in Additional Devon Energy Operated Well in Mississippi Lime Formation, Oklahoma North American Petroleum Plc, a company focussed on developing its interests in proven US onshore oil and gas formations, is pleased to announce its participation in its thirteenth well, which is targeting the proven Mississippi Lime formation, Oklahoma and is currently waiting to spud.

This is in line with the Companys strategy to build net production and reserves by acquiring and developing leases in liquids rich hydrocarbon plays. NAP has acquired a 0.464% working interest and a 0.348% net revenue interest (NRI) in the JKL 1-08HM (JKL), a horizontal well targeting the Mississippi Lime formation, Oklahoma operated by Devon Energy (Devon).

Under the terms of the acquisition, 25% of NAPs NRI will be reassigned (Back-in) to the farmor upon pay-out (i.e.

when drilling costs have been recovered).

Upon pay-out, NAP will therefore have a 0.261% NRI in JKL.

Total drill costs are estimated at US$3,723,000 with the Companys 0.464% working interest in the well estimated at US$17,290. North Americans Managing Director Stefan Olivier said, "As this latest Devon operated well shows, we continue to receive proposals to participate in new drilling on the 400 plus net mineral acres we have acquired since March.

We now have interests in 13 wells in proven US onshore formations at various stages of development, more than half our 12 month target of 25 set at the time of NAPs IPO.

Participating in wells to rapidly grow production is a key part of our strategy, with revenues generated from producing wells in which we have an interest being recycled into new drilling and the acquisition of additional leases.

I look forward to updating the market on our continued progress as we build a portfolio of producing assets and reserves and in the process create value for shareholders." **ENDS** For further information and the full Admission document visit www.napetroleum.com or contact the following: Stefan Olivier David Coffman North American Petroleum Plc Keith, Bayley, Rogers & Co. +44 (0) 7595 779520 +44(0) 203 100 8125 Frank Buhagiar St Brides Media and Finance Ltd +44 (0) 20 7236 1177 Lottie Brocklehurst St Brides Media and Finance Ltd +44 (0) 20 7236 1177
Notes North American Petroleum Plc acquires leases in producing onshore US formations such as the Mississippi Lime, Oklahoma, where the application of new techniques and technologies such as horizontal drilling and fracture stimulation can dramatically improve recovery rates.

Revenues generated out of production are reinvested into both new wells and into the acquisition of additional leases to build a portfolio of producing and undeveloped assets focussed on lower risk oil rich plays.

To date, NAP has acquired 416 net mineral acres in the liquids rich Mississippi Lime play and has interests in seven producing wells and a further six either drilling or waiting to spud. [cid:image001.png@01CE6036.597C4560]
