Rambler Achieves Record Throughput for 2017

With a 27% Increase in Ore Processed Year-over-Year

London, England - Newfoundland and Labrador, Canada - Rambler Metals and Mining plc (TSXV: RAB, AIM: RMM) ("Rambler" or "the Company"), a copper and gold producer, explorer, and developer is pleased to announce that for the fiscal year ending December 31, 2017 it achieved a record annual throughput by processing 339,631 tonnes of ore from the Ming Mine through the Nugget Pond copper and gold milling facility. A total of 3,968 tonnes of saleable copper and 3,357 ounces of gold were produced from this throughput.

2017 Production Summary

· For Q4 and the fiscal year the Nugget Pond copper and gold milling facility achieved record throughput for ore processed. The facility processed 97,997 dry metric tonnes ('dmt') at a feed grade of 1.17% copper and 0.65 g/t gold for the quarter with 339,631 dmt at 1.27% copper and 0.58 g/t gold for the 2017 fiscal year. The quarterly production included 17 days running at an average of 1,260 mtpd, confirming the Company's mill improvements should allow the facility to produce at a sustained rate at or greater than 1,250 mtpd.

· Recovery of metal to concentrate was 96.1% and 61.0% for copper and gold respectively for the quarter (95.6% and 60.7% for the 2017 fiscal year). Production of concentrate was 4,014 dmt containing saleable metal of 1,061 tonnes of copper and 1,112 ounces of gold. For the full year the operation produced 14,907 tonnes of concentrate containing saleable metal of 3,968 tonnes of copper and 3,357 ounces of gold.

· Revised guidance targets were met for mill throughput, copper and gold head grades and metal recovery to concentrate. Guidance for saleable metal produced was also met for copper and just under for gold.

· Rambler delivered on all of its safety targets during 2017. For the fiscal year there were no lost time incidents or medical aids, with the twelve-month rolling average lost time frequency rate remaining at 0%.

· Mine performance has shown significance improvements from Q4/17 compared to the same quarter in 2016. Mostly notably improvements include:

o Daily development meters increased 33% (Q4/17: 12.1 m/ day, Q4/16: 9.1 m/ day)

o Total material hauled increased 21% (Q4/17: 1,486 mtpd, Q4/16: 1,223 mtpd)

o Backfill placed increased 53% (Q4/17: 286 mtpd, Q4/16: 187 mtpd)

o Mine ore produced increase 38% (Q4/17: 1,061 mtpd, Q4/16: 767 mtpd)

Norman Williams, President and CEO, commented:

"I would like to thank each Rambler employee and contractor for their outstanding efforts, patience and achievements during 2017. In the last 17 months, we have nearly doubled the production rate at both the mine and the mill. This growth in production has been completed with safety at the forefront which is evident by the 2,310 days without a lost time accident and 1,114 days since its last medical aid. We appreciate your continued efforts as we work towards completing our Phase II transformation.

"The mine is now averaging ~1,118 tonnes of ore per day from the underground, with the mill hitting peak production as high as 1,360 mtpd while maintaining high copper recovery. Ore stockpiles at each site continue to be modest pending completion of the surface ventilation project. This project is on the critical path and targeting completion in March. Once finished the mine's ventilation system will be reversed allowing for increased capacity and improved cycle times thereby boosting the overall throughput from the mine.

 "Given the productivity improvements just around the corner we are now turning our attention to increasing the overall feed grade being delivered to the mill and returning the Company to positive cash flows during a time that has seen significant run up in, and positive outlook, on long term copper and gold price forecasts. The Company expects to complete its Phase II expansion with sustained production of 1,250 tonnes per day mining and milling towards the end of the first quarter, 2018."

Rambler's ongoing Phase II plans are to sustain mine and mill production at 1,250 mtpd in 2018. This initial expansion has been fully funded through CEII's investment. Rambler will also continue advancing Phase III engineering studies with a view to further increase production to 2,000 mtpd at the Ming Mine.

Along with the Ming Mine, Rambler also owns 100 per cent of the former producing Little Deer/ Whales Back copper mines and has strategic investment in the former producing Hammerdown gold mine.
