Prefeasibility Study Outlines Optimisation Plan of
Canadian Copper Producer with 45 per cent IRR and 21 Year Mine Life

London, England & Baie Verte, Newfoundland and Labrador, Canada - Rambler Metals and Mining plc, a Canadian copper and gold producer, explorer and developer (TSX- V: RAB; LSE: RMM) ("Rambler" or the "Company") today reports that it has completed a pre-feasibility engineering study and economic assessment ('PFS') aimed to integrate the Lower Footwall Zone ('LFZ') mineral resource into the life of mine ('LOM') plan for the Ming Copper-Gold Mine.

The PFS was successful in defining a staged, low capital strategy for the optimisation of all existing infrastructure allowing the operation to run at full capacity of 1,250 metric tonnes per day ('mtpd') by 2018.

The results show positive economics, a strong internal rate of return and significant cash flow under reasonable commodity price assumptions. In addition, there remain further opportunities for improvement as the operation becomes fully optimised.
