Rambler Hits Record Throughput as it

Delivers its Phase II Transition to 1,250 mtpd.

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 announced that for the month of November 2017 it processed 33,870 tonnes of ore from the Ming Mine through the Nugget Pond mill, averaging 1,221 metric tonnes per day ("mtpd") during operational hours. November's performance represents record monthly throughput for the operation.

November 2017 Production Summary

· During November, the Nugget Pond copper and gold milling facility achieved record throughput. The facility processed 33,870 dry metric tonnes ('dmt') at a feed grade of 1.19% copper and 0.75 g/t gold, averaging 1,221 mtpd during operational hours, including 17 days running at an average of 1,260 mtpd.

· At the mine, ore delivered to surface averaged 1,140 mtpd during the month, with several underground development headings nearing key production areas. The operation plans to produce an average of 1,125 mtpd during December and January as it completes the final upgrades to the ventilation system, which will in turn allow for increased activity and faster clearing times in the mine.

· Recovery of metal to concentrate was in line with expectations and guidance returning 96.4% and 61.2% for copper and gold respectively. Production of concentrate was 1,376 dmt containing saleable metal of 374 tonnes of copper and 449 ounces of gold.

· Targeting record mill throughput in Q4 reaching 100,000 dmt of ore delivering approximately 2.4M pounds of saleable copper and 1,375 ounces of salable gold.

Norman Williams, President and CEO, commented:

"There has been a significant amount of work completed at the Ming Mine and Nugget Pond mill following the expansion financing completed in June, 2016. While mine development itself was initially slower than anticipated, the team has been successful in improving its performance in a short period of time and is now operating at nearly double its previous throughput rate of 650 mtpd. We are now turning our attention to increasing the grade of mill feed while maintaining the 1,250 mtpd rate. On behalf of myself, and the entire Board of Directors, we would like to thank the operations team for their tremendous effort and dedication in making this Phase II transformation a reality.

 "While we are nearing a significant milestone for the Company, this marks just the beginning of the next phase of growth for Rambler. This deposit has the ability to sustain a high throughput over a long mine life, currently 20 years. In addition, our recent surface exploration program has confirmed our understanding that the grades and thickness of the LFZ mineralization continue to improve at depth. We are excited about the opportunities and potential of this deposit and look forward to further engineering studies demonstrating the viability of a 2,000 mptd production profile."

ABOUT RAMBLER METALS AND MINING

Rambler is a mining and development company that in November 2012 brought its first mine into commercial production. Rambler has a 100 per cent ownership in the Ming Copper-Gold Mine, a fully operational base and precious metals processing facility and year round bulk storage and shipping facility; all located on the Baie Verte peninsula, Newfoundland and Labrador, Canada.

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.

Rambler is dual listed in London under AIM:RMM and in Canada under TSX-V:RAB.
