                 Magnolia Petroleum Plc ('Magnolia' or 'the Company')              

                               Q4 2016 Operations Update                           

    Magnolia Petroleum Plc, the AIM quoted US focused oil and gas exploration and
    production company, is pleased to announce a quarterly update for Q4 2016 ('the
    Quarter') on its operations across proven and producing US onshore hydrocarbon
    formations, including the Bakken/Three Forks Sanish in North Dakota, and the
    Woodford, Mississippi Lime and the Hunton in Oklahoma. 

    Q4 Highlights to 31 December 2016

      * Two new wells commenced production during the Quarter
      * 153 producing wells in the Company's portfolio as at end of Q4 2016
      * Elected to participate in five new wells during the Quarter
      * Nine wells currently at various stages of development
      * Raised £225,000 to fund drilling commitments on its US onshore leases (see
        announcement of 27 October 2016 for further details)

    Outlook

      * New wells due to come into production in Q1 2017
      * Participation with leading operators in new wells and infill drilling which
        are commercial at lower oil prices
      * Updated Reserves Report as at 1 January 2017 due in the near-term
      * On-going lease acquisition and management activity in line with strategy to
        grow and diversify portfolio

    Magnolia COO, Rita Whittington said, "Thanks to two new wells coming on stream
    during the Quarter and following the divestment of 67 producing wells with
    little or no economic value in 2016, Magnolia ended the year with a portfolio
    of 153 producing wells located in proven US onshore formations.

    "With WTI consistently trading above the US$50 level on the back of the recent
    OPEC meeting and our cost base almost a third lower than it was a year ago,
    Magnolia is well placed to step up our level of drilling activity once a
    recovery in sentiment has become firmly entrenched. With this in mind, we are
    encouraged by the noticeable pick up we are seeing in planned drilling by
    operators in our areas of focus; while on a wider level the near 10% month on
    month increase in the US rig count to 634 in December 2016 bodes well.  Our
    strategy and objective remains the same: to drill alongside established
    operators to prove up the reserves on our leases, and in the process generate
    value for our shareholders."
