                       CLONTIBRET PROJECT BY TETRA TECH 
 
  * Indicated resource grade increased to 2.1 g/t Au in lodes 
  * Indicated resource category increased to 320,000 ounces (Au) 
  * Cut off of 1g/t Au applied 
  * Structural continuity of lode mineralisation demonstrated

Conroy Gold and Natural Resources plc (AIM: CGNR; ESM: CGNR.I) the gold 
exploration and development company focused on Ireland and Finland, is pleased 
to announce that it has received an Updated Mineral Resource Estimate prepared 
by Tetra Tech Canada Inc. ("Tetra Tech") on its wholly owned Clontibret gold 
project in Co. Monaghan, Ireland.  The new resource estimate was developed to 
Joint Ore Reserves Committee ("JORC") standard and represents a detailed 
geological revision and update on the scoping study previously undertaken by 
Tetra Tech (2011).

Notes: 
 
  * Mineral Resources do not have demonstrated economic viability but have 
    reasonable prospects for eventual economic extraction 
  * The effective date of the Mineral Resource is 17th July 2017 
  * Mineral Resources have been reported above a (1.0 g/t cut-off) 
  * Numbers may not add exactly due to rounding. 
  * Resource Estimate was prepared by Mr. Robert Davies B.Sc., European 
    Geologist (EurGeol) and Chartered Geologist (CGeol).  Mr Davies is a Senior 
    Resource Geologist and Competent Person as defined by the JORC code. 
  * The last site visit was conducted by Mr. Joe Hirst B.Sc, M.Sc., European 
    Geologist (EurGeol) and Chartered Geologist (CGeol), between the 25th and 
    27th of November 2015. Mr Hirst is a Resource Geologist and Competent 
    Person as defined by the JORC code. 
 
The Mineral Resource Statement has been classified and reported in accordance 
with the guidelines defined in the Australasian Code of Reporting of 
Exploration Results, Mineral Resources and Ore Reserves (The JORC Code, 2012). 
 
The Clontibret deposit comprises two styles of gold mineralisation (i) lodes 
and (ii) stockwork.  This updated resource estimate focused on determining the 
grade and continuity of the lode mineralisation where over 95% of the contained 
ounces occur.  The stockwork resource still contributes to the overall 
contained ounces. 
 
Compared with the 2011 Tetra Tech study, this new resource estimate represents 
an increase in gold grade of 26% and an increase in contained ounces in the 
indicated category of 23%. 
 
As part of this study additional opportunities to increase the size of the 
resource have been identified.  There is strong geological evidence to suggest 
that the lodes have a more extensive strike length than previously interpreted 
- up to at least 850m.  Mineralisation remains open in all directions. 
 
Resource Estimate 
 
Prof. Garth Earls EurGeol, PGeo, FSEG, Conroy's Consultant Geologist, in 
association with Conroy Senior Geologists Kevin McNulty, EurGeol, PGeo, FSEG 
and Andrew Murrells EurGeol, PGeo re-interpreted the geology to include the 
latest drilling and to improve the continuity in the correlation of the 
mineralised lodes.  This information was used as a basis for the new Resource 
Estimate completed by independent mining consultants, Tetra Tech. 
 
The new Resource Estimate for the Clontibret project is being disclosed in 
accordance with Joint Ore Reserves Committee (JORC) 2012.  The estimate 
includes 85 diamond drillholes, with a drill spacing typically ranging from 25 
to 50 m (see JORC Table 1 below). 
 
The Company provided Tetra Tech with a coded drillhole database and sectional 
interpretations to guide the wireframe model construction.  In total 46 
individual lodes and a stockwork body were identified by Conroy. The lodes 
generally have a north / south strike, dipping to the west at between 60 and 70 
degrees.  The strike of the stockwork zone trends north east / south west, 
dipping to the north west at approximately 50 degrees.  The mineralised lodes 
penetrate into the stockwork body, terminating against the footwall of the 
stockwork (Figure 1).

The lodes and stockwork are distinct geological domains that have been 
estimated separately.  Bulk density has been estimated into the block model 
based on 346 samples averaging 2.712 grams per cubic centimetre (g/cm3). The 
grade interpolation was by the Ordinary Kriging (OK) method.

Professor Richard Conroy, Chairman, commented: 
 
"This update confirms a grade increase of 26% above the previous estimate and a 
23% increase in contained ounces in the indicated category with a robust cut 
off of 1g/t Au.  Significantly, the structural continuity of the lodes has been 
established."

Sampling       * Nature and quality of sampling (e.g. cut channels, 
techniques       random chips, or specific specialised industry 
                 standard measurement tools appropriate to the 
                 minerals under investigation, such as down hole 
                 gamma sondes, or handheld XRF instruments, etc.). 
                 These examples should not be taken as limiting the 
                 broad meaning of sampling. 
               * Include reference to measures taken to ensure 
                 sample representivity and the appropriate 
                 calibration of any measurement tools or systems 
                 used.

                 are Material to the Public Report. 
               * In cases where 'industry standard' work has been 
                 done this would be relatively simple (e.g. 'reverse 
                 circulation drilling was used to obtain 1 m samples 
                 from which 3 kg was pulverised to produce a 30 g 
                 charge for fire assay').  In other cases more 
                 explanation may be required, such as where there is 
                 coarse gold that has inherent sampling problems. 
                 Unusual commodities or mineralisation types (e.g. 
                 submarine nodules) may warrant disclosure of 
                 detailed information.
