Rambler Begins Trucking Copper Concentrate Following Start-up And Commissioning of its New Floatation Facility

LONDON, ENGLAND and BAIE VERTE, NEWFOUNDLAND AND LABRADOR--(Marketwire - May 30, 2012) - Rambler Metals and Mining plc
(TSX VENTURE:RAB)(AIM:RMM) ('Rambler' or the 'Company') is pleased to announce the commencement of copper concentrate
production with ore from its 100% owned Ming Copper-Gold Mine ("Ming Mine") in Newfoundland and Labrador's Baie Verte
Peninsula, Canada.

COPPER PRODUCTION HIGHLIGHTS

--  On 14 May 2012 the Company officially began its copper production. First
    concentrates have now been trucked and are being stored at the port
    shipping warehouse

--  To date, all material processed has been commissioning ore from the
    Lower Footwall Zone with an average head grade of 1.30% copper.
    Flotation kinetics have been fast with an average throughput of 35
    tonnes per hour

--  Mill recoveries are averaging 95%, producing a clean copper concentrate
    grading between 25% and 31%

--  12,132 tonnes of lower grade ore remain stockpiled for commissioning
    grading 1.39% copper. Followed by 3,022 tonnes grading 4.53% copper and
    another 2,769 tonnes of moderate grade, 2.80% copper

--  Development headings for the 1807 ore zone are being prepared on the
    338, 346, 361 and 375 levels with diamond drill holes returning
    encouraging results:

George Ogilvie, President and CEO, commented:

"A major milestone for the Company has been achieved with the commencement of copper concentrate production. To date,
concentrator commissioning has been going well and we are pleased that copper recoveries are exceeding expectations at
such an early stage. Over the coming weeks, once the plant has been fully commissioned and optimized, we will begin
blending the stockpiled ore from the higher grade 1807 zone."

"Commissioning the copper concentrator with Lower Footwall Zone ore will also provide invaluable information on its
processing characteristics, which the Company can then use in future optimization and feasibility studies."

COPPER PRODUCTION

Live ore commissioning of the copper concentrator officially began on 14 May 2012. Over the last two weeks,
approximately 6,624 tonnes has been processed at an average throughput of 35 tonnes per hour (tph). Daily production
will continue to fluctuate over the coming weeks as the entire system is optimized before being automated with a more
consistent throughput.

To date, copper recovery in the newly constructed facility has been exceptional. Recoveries during plant start-up have
ranged between 91% and 99% and are now averaging close to 95%. This is again a significant improvement over internal
forecasts which have been nominally calculated at 92.4%. The copper concentrate grade has ranged between 25% and 31%
copper, which is in line with the Company's forecast grade of 28% copper. With further experience on ore processing
capabilities from varying high grade feed sources, the Company will then be in a position to communicate its production
forecasts on a quarterly and annual basis.

The Company is on track to reach commercial production in the second half of 2012.

Definition diamond drilling in the 1807 zone on the 346, 361 and 375 levels has returned a number of encouraging
results. With blending of this zone expected to begin in June, the resultant copper concentrate produced is expected to
be of high quality. The table below summarizes the results of some of the diamond drill core samples taken to date.

ABOUT RAMBLER METALS AND MINING

Rambler Metals and Mining plc is a Junior Mining Company that has 100% ownership of the Ming Copper-Gold Mine in Baie
Verte, Newfoundland and Labrador, Canada. As a producing gold and copper miner, our objective is to become a mid-tier
mining company by continuing the development of the Ming Mine, discovering new deposits and through mergers and
acquisitions.

The initial six years of the Ming Mine project is based on the underground mining of massive sulphides with a mineable
reserve estimate of 1.498 million ore tonnes grading 1.62% copper, 2.40 g/t gold and 10.90 g/t silver (24,252 tonnes of
copper, 115,549 ounces of gold and 525,139 ounces of silver of contained metal). All massive sulphide zones remain open
both up and down plunge with the current exploration program focused on extending the known mineralization for inclusion
in the resource/reserve estimate.

In addition to the outlined reserve estimate, there is a sizeable footwall deposit beneath the massive sulphide horizon
that has been outlined with an indicated resource grade of 18,306k tonnes grading 1.43% copper (261,258 tonnes of
contained copper at a 1.00% copper cut-off grade). This zone forms the basis of the preliminary economic assessment,
compiled by independent consultants, which envisions the Ming Mine transitioning itself into a bulk tonnage mining
operation. For further information on the Ming Mine project, please refer to the Company's NI 43-101 compliant technical
reports, available under the Company's profile on SEDAR (www.sedar.com).

Over the coming months and years, as the Company seeks to optimize the Ming Copper-Gold Mine into a cash positive
position, it is expected that future expansion into the footwall zone will be formalized with the goal of maximizing
returns for shareholders and increasing the life of the mine.

Larry Pilgrim, P.Geo., is the Qualified Person responsible for the technical content of this release and has reviewed
and approved it accordingly. Mr. Pilgrim is an independent consultant contracted by Rambler Metals and Mining plc.

Drill hole referenced tonnes are dry metric tonnes while milling throughputs are quoted as wet tonnes unless otherwise
