Third Quarter 2015 Production Results

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 operational update for its third quarter ending 30 April 2015 ('Q3/15').

Q3/15 operating cash flow is expected to be positive with a projected return to overall profitability for the quarter. The Company is targeting to meet the bottom end of its revised production forecast.

Highlights OF the quarter:

· The Group continues to implement the January 2015 revised mine plan with mine production meeting planned targets;

· Towards the end of the quarter tonnage through the concentrator averaged over 700 mtpd, and continues at this level to date. Significant amounts of snowfall early in the quarter reduced mill production during the quarter;

· For the quarter head grades for copper averaged 2.71 per cent; gold at 1.12 grammes per tonne; silver at 7.88 grammes per tonne. Recoveries to concentrate for copper were 97.10 per cent, gold 74.36 per cent and silver 78.93 per cent;

· For Q3/15 there was production of: 1,043 tonnes of copper; 1,106 ounces of gold; 8,305 ounces of silver. Dry tonnes milled of 42,747 tonnes, representing a 13 per cent decrease on Q3/14 results and a 22 per cent decrease on Q2/15;

· Production of 3,989 tonnes of copper concentrate representing a 14 per cent decrease over Q2/15. Concentrate grade of 26.15 per cent, 8.63 grammes per tonne and 64.75 grammes per tonne for copper, gold and silver respectively; and

· With the implemented cost efficiency measures still in effect, operating cash flow for the quarter is expected to be positive. Despite the lower than planned throughput during Q3 the Company is projecting a return to overall profitability for the quarter. Further details will be announced on or before 25 June 2015 with the release of the complete financial statements.

Norman Williams, CA, President and CEO, commented:

"With the winter season now behind us, during May, we have averaged 712 mtpd through the copper concentrator, a 10 per cent increase over what we anticipated. We have also maintained positive operating cash flow which should continue for the remainder of the fiscal year at a higher than planned milling rate.

"The operations team were able to push mill throughput, and they now have a better understanding of the milling capacity as the Company continues to optimize the newly purchased two stage crushing unit, installed during the second quarter. This work will provide long term benefits as we begin integrating Lower Footwall material into the production stream.

"This has been the first full quarter since the revised mine plan was implemented in January. The Company continues to review the mine plan for ways to improve production throughput and grade for the remainder of the fiscal year."

Q3 OPERATIONAL SUMMARY

For fiscal Q3/15 the Company milled 42,747 dry metric tonnes of ore and produced 3,989 tonnes of copper concentrate containing 1,043 tonnes of copper metal, 1,106 ounces of gold and 8,305 ounces of silver. The average feed grade during this period was 2.71 per cent copper, 1.12 grammes per tonne gold and 7.88 grammes per tonne silver followed by a mill recovery of 97.10 per cent, 74.36 per cent and 78.93 per cent for copper, gold and silver respectively.

The Company first declared commercial production in November 2012 and has since milled 509,055 dry metric tonnes producing 53,157 tonnes of copper concentrate containing 15,199 tonnes of copper metal, 13,898 ounces of gold and 105,461 ounces of silver.

The third quarter of the Company's fiscal year marks the end of a difficult winter season with above average snow fall and cold conditions. These conditions did impact production through the copper concentrator during February and March however, late in the quarter we were able to push mill throughput and gained a better understandingof the crusher's capabilities and feed through the coarse ore bin. The optimization of these units are an important component for the Company's plans to double mill production over the next three years.

Presently the mine and mill are meeting the monthly production targets with May's mill's production now averaging over 712 mtpd. The Company is targeting to meet the bottom end of its revised production forecast.

Details of the Company's financial performance, including capital expenditure and operating costs, will be included in its Q3/15 financial results to be released on or before Thursday 25 June 2015.
