Progress Update on the Lower Footwall Zone

London, England & Baie Verte, New foundland and Labrador, Canada - Rambler Metals and Mining plc (TSXV: RAB, AIM: RMM) ("Rambler" or "the Company"), a copper and gold producer, explorer, and developer today provides an update on the Dense Media Separation ('DMS') project and the pre-feasibility study ('PFS') associated with the Lower Footwall Zone ('LFZ').

HIGHLIGHTS

Pre-Feasibility Study

· On 2 December 2014 the Company announced a Mineral Resource for the Lower Footwall Zone to contain an estimated 839,593,090 pounds of copper, 87,667 ounces of gold and 1,071,176 ounces of silver in the Measured and Indicated categories. None of this mineralization is included in the current reserve estimate for the Ming Copper-Gold Mine. Tables 1 and 2 under Appendix 1 provide additional information on the existing mineral reserve and resource estimates

· The Company has engaged independent third party consultants to evaluate the mining potential of the Lower Footwall Zone resource. The initial plan, Phase 2, will evaluate a production rate up to 1250 metric tonnes per day under a staged, low capex, expansion programme

· The objective of the PFS will be to demonstrate the viability of a ten year life of mine, or more, utilizing the full capacity of the existing copper concentrate and all mineralized zones within the Ming Copper-Gold Mine

· The engineering and evaluation work is targeting a completion date of June 2015

Dense Media Separation ('DMS') Project

· At Nugget Pond the construction and commissioning of the on-site demonstrate plant has been completed with optimization and testing underway. The onsite demonstration program has been designed to scale up the results seen in previous work

· Bench scale and pilot testing have indicated that technically the DMS process could increase the grade of copper in the LFZ by removing 30 per cent to 40 per cent of the lighter waste host rock with copper recoveries averaging 95 per cent. In terms of grade improvement, the mini-pilot testing using run of mine material from the LFZ grading 1.39 per cent copper returned a pre-concentrate grade of 2.27 per cent copper (an upgrade ratio of 1.63)

Norman Williams, President and CEO, commented:

"While mining of the high grade massive sulphides has established the Company, the future of the mine lies within the Lower Footwall Zone. The LFZ resource update published in December 2014 showed a significant increase in contained metal for the mine and, through the pre-feasibility study, we are working towards demonstrating the viability of extracting this material.

"Through a staged low-capital expansion program we hope to fully utilize the existing copper concentrator at the Nugget Pond milling facility, optimize production at the Ming Mine while taking full advantage of the abundant LFZ resource.

"Further to the announcement dated 30 January 2015 ( "Rambler Implements Revised Plan at the Ming Copper-Gold Mine") the Company has implemented its short term cost cutting measures with the view to reduce operating expenditures to bring costs more in line with expected production under the current commodity markets. The initial response to these essential changes has been encouraging however it will take time to measure the full impact these changes will have on the operation.

"Further updates and results will be communicated as we continue forward with the revised mine plan."

Lower Footwall Zone Pre-Feasibility Evaluation

The pre-feasibility of the Lower Footwall Zone has been commissioned with the assistance of WSP Canada Inc. ('WSP'), Pakalnis and Associates ('Pakalnis'), Thibault and Associates Inc. ('Thibault') and West Coast Engineering Limited ('WCEL'). WSP and Pakalnis will focus on the mining aspect of the expansion while Thibault and WCEL will oversee all improvements required at the mill site.

Currently the operation is running under its Phase 1 high grade and low tonnage start-up plan. The PFS has been commissioned to evaluate the mining potential of the LFZ, Phase 2. Phase 2, will consider a mine and mill expansion up to 1250 metric tonnes per day ('mtpd') under a staged, low capital programme. This portion of the work will not include ore pre-concentration with DMS technology but will serve to demonstrate the least risk option with straight run of mine ore. All groups are working towards a completion date for this phase of the project on or before June 2015.

Following the completion of Phase 2 the Group will further assess the results of the DMS pilot programme, and the ongoing test work at Nugget Pond, to evaluate the potential of integrating ore pre-concentration into the mine's production stream, Phase 2a. Under this scenario the mine itself will likely operate at a higher production rate allowing for further optimization while looking to lower mining costs through economies of scale. A lower copper cut-off grade may also be possible under this plan taking advantage of more of the Lower Footwall Zone resource. It is envisioned the mill will also operate at 1250 mtpd under the Phase 2a scenario with consideration given to the future use of the now idle gold leaching and hydromet facility.

Calendar 2015 will be a transformational year for the Company as it continues working towards demonstrating the flexibility of the Baie Verte operations with the potential of the Lower Footwall Zone while taking full advantage of all assets at the mine, mill and port sites.

Dense Media Separation ('DMS') Project

The mineralization of the Lower Footwall Zone consists of dense, narrow copper rich stringer sulphides hosted within lighter weight, un-mineralized, chlorite schist. The initial phase of bench scale and mini-pilot testing, developed with the assistance of the Research & Development Corporation of Newfoundland and Labrador ('RDC'), has revealed that physical separation of the denser mineralization from the lighter rock using DMS is possible. The work indicated that technically the DMS process could increase the grade of copper in the LFZ by removing 30 per cent to 40 per cent of the lighter waste host rock with copper recoveries averaging 95 per cent. In terms of grade improvement, the mini-pilot testing using run of mine material from the LFZ grading 1.39 per cent copper returned a pre-concentrate grade of 2.27 per cent copper (an upgrade ratio of 1.63).

The mining portion of the DMS Project was completed in December 2014 with over 15,000 tonnes of material stockpiled on surface for testing. At Nugget Pond the construction and commissioning of the on-site demonstrate plant has been completedand final testing is underway. The onsite demonstration program has been designed to scale up the results seen in previous work. Further updates on the progress of the DMS and prefeasibility work will be released over the coming months.
