Harvey Licence Valuation Update

Independent Oil and Gas plc ("IOG" or the "Company"), the development and production focused Oil and Gas Company, is pleased to announce the recent Competent Persons Report ("CPR") by ERC Equipoise Limited ("ERCE"), has been updated to include a fully risked, expected monetary value ("EMV") for the Harvey licence.

Highlights

·      Fully risked EMV for the 100%-owned Harvey licence of £79 million.

·     Best estimate gross unrisked post-tax NPV10 of £159 million for the overall Harvey structure and £126 million for the licence.

·   The EMV has been calculated on the mean of the Low/Best/High estimates of the prospective resources following the derivation of Harvey production profiles.  Low/Best/High estimates of unrisked prospective gas resources are 45/114/286 BCF on the Harvey structure, 36/90/226 BCF on licence.

·      Firm commitment made to drill the Harvey well within 2 years, subject to acceptance and a licence extension by the OGA.  Well scheduling under consideration.

EMV is an economic metric used to evaluate investment opportunities and ensure that project economics justify both initial and overall expenditure.  The CPR author estimates dry hole costs of the planned Harvey well at £8.5 million, versus a licence EMV of £79 million.  IOG therefore sees a compelling case for drilling Harvey and is actively considering the timing.  In the CPR success case, the EMV assumes an appraisal well in H1 2018, Final Investment Decision in H1 2019 and first gas in Q1 2021.  The calculation is on a standalone post-tax basis without accounting for IOG's existing tax loss position.  The EMV is based on equivalent economic assumptions to the recent Blythe hub and Vulcan Satellites hub CPR.  The executive summaries of both CPRs are available on the IOG website: -

The unrisked NPV10 post tax values and prospective resources are as follows: -

The Geological Chance of Success of 50% has been applied to the mean of these values to calculate the EMV.

As advised previously the Competent Person estimates that approximately 21% of the Harvey structure is not on IOG's licence.  Plans are underway to licence all the Harvey resources.

Mark Routh, CEO and Interim Chairman of IOG commented: -

"We are delighted with the result of the CPR and the EMV of the Harvey structure on our licence being determined at £79 million.  This clearly validates our commitment to drill the well on what has the potential to become our largest gas asset.  The value of Harvey is strengthened by the synergies with our Southern North Sea gas development hubs, notably shared use of a fully owned Thames Pipeline gas export route.  Alongside these two hubs, the Harvey appraisal opportunity therefore represents very material upside to IOG even on the mid case volumes.  We are therefore actively considering how soon we can drill the well.  We look forward to updating all stakeholders in due course."
