    findings, and further details will be communicated to shareholders in due
    course. In the meantime, Baker Hughes' revised Oil-In-Place estimates can be

    Background
    In 2016 the Company contracted Halliburton to carry out a Vertical Seismic
    Profile (VSP) survey based on US Oil's Eblana #1 discovery well, and Baker
    Hughes (BHI) to carry out structural modelling based on all the available data
    including VSP. The purpose of the structural modelling was to reduce risk as
    far as possible before the Company carries out its plan to re-enter the Eblana
    #1 well and sidetrack to identified targets. In addition, Baker Hughes
    calculated the revised Oil-In-Place estimates reported above for the Tertiary
    Structure updip of the Eblana #1 well.  These estimates do not include the
    Palaeozoic strata, which may also be highly prospective.  Baker Hughes is
    currently working on revised Oil-In-Place estimates for the Company's full 88
    sq km lease acreage, and these will be reported in due course.

    Work programme
    The Company is now moving forward rapidly with its corporate and operational
    agendas.  The Board and the US Oil technical team will now take time to study
    the Baker Hughes report. Meanwhile, discussions with drilling contractors are
    taking place, and a detailed drill plan is being prepared. 

    Fundraising efforts continue with the primary aim of maximising resources for
    drilling operations.
