Rambler's JV Partner Provides an Update on

Diamond Drilling at the Little Deer Copper Deposit

London, England & Baie Verte, Newfoundland and Labrador, Canada -Rambler Metals and Mining plc (TSXV: RAB, AIM: RMM) ('Rambler' or the 'Company'), a copper and gold producer operating in Newfoundland and Labrador, Canada, today provides an update on the diamond drilling at the Little Deer Project through its Joint Venture partner Thundermin Resources Inc. (TSXV:THR) ('Thundermin').

Thundermin Resources Inc. ("Thundermin") (THR:TSX-V) and 50% joint venture partner Rambler Metals and Mining Canada Limited ("Rambler") (RAB:TSX-V; RMM:AIM) announce that they have intersected 2.9% Cu over 3.4 m and 3.8% Cu over 2.0 m, 2.1% Cu over 2.6 m, and 2.3 % Cu over 6.2 m in two separate drill holes on the Little Deer Copper Deposit ("Little Deer") located approximately 10 kilometres north of Springdale in north-central Newfoundland (see Table 1 and Figure 1).

Table 1: Little Deer Drill Results (2014)

Notes:

1)* The reported copper intersections are core lengths. The true thicknesses of the various copper intersections are highly variable due to the stringer nature of the mineralization.

2) The "A" suffix in the drill hole number indicates a wedge hole.

The recently completed 3,800 metre drill program, which was designed to increase the mineral resources outlined to date and to further upgrade the inferred resources to the indicated resource category in the eastern portion of the deposit, consisted of four new holes and two wedge holes. Holes LD-14-63, 63A and 65 all intersected the Little Deer Main Zone. Hole LD-14-65 also intersected two new copper zones higher in the hole grading 3.8% Cu over 2.0 m, from 206.5 m to 208.5 m down the hole, and 2.1% Cu over 2.6 m, from 414.8 to 417.4 down the hole. These two new copper zones were intersected within a previously unknown, large chlorite alteration zone and their lateral and depth extent is unknown at the present time. Holes LD-14-64, 64A and 66 appear to have been "dyked out" as they all intersected minor amounts of copper mineralization within intensely chlorite altered mafic volcanic rocks, within the expected area of the Little Deer Main Zone, before intersecting thick sections of gabbroic dyke.

John B. Heslop, President and Chief Executive Officer of Thundermin said "we are generally pleased with the results of the current drill program and continue to define continuity of the copper mineralization between wide-spaced, historical drill holes. We have intersected various dykes in previous drilling but not generally within the copper mineralization. We are currently compiling the recent drill information and selecting additional holes to be drilled in order to improve the confidence level of the National Instrument 43-101 ("NI 43-101") compliant resources at Little Deer prior to undertaking a pre-feasibility study. In particular, we would like to confirm and expand the mineral resources in the Little Deer Footwall Zone Splay that is estimated to contain 797,000 tonnes ("t") grading 2.64% copper (see news release dated June 22, 2011).

The Little Deer Copper Project hosts the Little Deer and Whalesback copper deposits. On June 22, 2011 and July 26, 2012, NI 43-101 compliant mineral resource estimates, which were undertaken by P&E Mining Consultants Inc. ("P&E") of Toronto, Ontario, were announced for Little Deer and Whalesback, respectively. P&E estimated that Little Deer contains indicated resources of 1,911,000 t at an average grade of 2.37% Cu (99.8 million lbs. Cu) and additional inferred resources of 3,748,000 t at an average grade of 2.13% Cu (176.0 million lbs. of Cu). P&E estimated that Whalesback contains indicated resources of 797,000 t grading 1.67% Cu (29.3 million lbs. Cu) and inferred resources of 443,000 t grading 1.57% Cu (15.3 million lbs. Cu). On a combined basis, Little Deer and Whalesback are estimated to contain indicated resources of 2,708,000 t grading 2.16% Cu (129.1 million lbs. Cu) and inferred resources of 4,191,000 t grading 2.07% Cu (191.3 million lbs. Cu). A complete summary of the mineral resources outlined to date on the Little Deer Copper Project can be found on Thundermin's website, in news releases and on SEDAR.
