Reserves and Resources Statements for the Lidsey and Brockham Oil Fields, UK
Doriemus Plc (AIM: DOR) today announces the conclusions of the independent
reserve and resource reports ("CPR") by RPS Energy Consultants Limited ("RPS")
for both the Lidsey and Brockham Fields in the Weald Basin, UK for the operator
Angus Energy Ltd ("Angus Energy").
Doriemus has a 20% participating interest in the Lidsey Field and a 10%
participating interest in the Brockham Field. Angus Energy is operator of both
Fields and owns 70% of the Lidsey Field and 80% of the Brockham Field.
Highlights:
* Lidsey Field (20% Doriemus)
* oil in-place P50 best case of 9.52 MMstb (gross)
* 2P reserves of 36.0 Mstb (gross)
* 2C contingent resources of 413.6 MMstb (gross)
* Brockham Field (10% Doriemus)
*
+ Oil in-place P50 best case of 3.62 MMstb (gross)
+ 2P reserves of 47.0 Mstb (gross)
The CPRs calculate the reserves and resources with an effective date of 31
December 2013. A new reserve and resource report will be commissioned after the
drilling of the Brockham side-track well, due to start before the end of March
2014, and the drilling of the new Lidsey-2 well to be drilled during April and
May 2014.
The gross in-place volumes for the Brockham Field are as previously announced
on 28 February 2014.
Donald Strang, the Company's Chairman, commented:
"There is a combined 13 million barrels gross barrels of contained oil within
these two conventional oil fields south of London (2.26 million barrels
attributable to Doriemus). The Company is anticipating production to
substantially increase at both the Brockham Field, after the side-track well is
completed in April 2014, and at the Lidsey Field, on completion of the new
Lidesy-2 well before June 2014."
Competent Person's Statement:
The information contained in this announcement has been prepared by RPS Energy

EVALUATION OF LIDSEY AND BROCKHAM FIELDS, ONSHORE UK
In response to Angus Energy Limited's request of February 2014 and the Letter
of Engagement dated 5th February 2014 with Angus Energy Limited (the
"Agreement"), RPS Energy Consultants Limited ("RPS") has completed an
independent evaluation of liquid hydrocarbons in Licence PL241 in the United
Kingdom (the "Properties") in which Angus Energy Limited ("Angus") has an
interest.
This report is issued by RPS under the appointment by Angus Energy Limited and
is produced as part of the Services detailed therein and subject to the terms
and conditions of the Agreement.
This report is addressed to the Company and Third Parties as defined in the
Agreement and is only capable of being relied on by the Company and any Third
Parties under and pursuant to (and subject to the terms of) the Agreement.
The Company may disclose the signed and dated report to third parties as
contemplated by the Purpose defined in the Agreement but in making any such
disclosure the Company shall require the third party (including any Sponsor and
Third Parties) to accept it as confidential information only to be used or
passed on to other persons as the Company is permitted to do under the
Agreement.
The report is based on data and information available up to February 28th 2014.
An effective date of 31st December 2013 has been assumed for the evaluation.
The Services have been performed by an RPS team of professional petroleum
engineers, geoscientists and economists and is based on the Operator's data,
supplied through Angus. All Reserves and Resources definitions and estimates
shown in this report are based on the 2007 SPE/AAPG/WPC/SPEE Petroleum Resource
Management System ("PRMS").
Our approach has been to review the Operator's technical interpretation of
their base case geoscience and engineering data for the field for
reasonableness and to review the ranges of uncertainty for each parameter
around this base case in order to estimate a range of petroleum initially in
place and recoverable.
