London, England & Baie Verte, Newfoundland and Labrador, Canada - Rambler Metals and Mining plc (TSXV: 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 Labradors Baie Verte Peninsula, Canada.
COPPER PRODUCTION HIGHLIGHTS o 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 o 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: HOLE ID Heading From (m) To (m) Length (m) Cu (%) Au (g/t) Ag (g/t)

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."
