And Commissioning of its New Floatation Facility
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

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:

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."
