Rambler Releases Q1 2017 Production Results & Development Update

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 today provides production results for first quarter ended 31 March 2017 ('Q1/17').

Q1/17 Production Summary

· Copper feed grade of 1.13% with gold grades of 0.30 g/t. Total mill throughput for the period ending was 75,438 dry metric tonnes ('dmt'). During the period the plant averaged 910 metric tonnes per day ('mtpd') during operational hours.

· Average recoveries to concentrate for the quarter were: copper 96.6% and gold 64.0% with a concentrate grade of 28.2% and 5.2 g/t for copper and gold respectively.

o The mill produced 2,930 dmt of concentrate containing saleable metal of 794 tonnes of copper and 391 ounces of gold.

Development Update

· Mining focus in the first quarter was on the underground development necessary to achieve the company's growth target of sustainable production of 1,250 mtpd during the second half of the calendar year.

· Heavy underground development into the Lower Footwall continued during the quarter.

· Mill throughput averaged 910 mtpd per operational hour, with final plant modifications being made to allow for 1,250 mtpd. All work to be completed over the coming months.

· Rambler is on track to reach sustainable production of 1,250 mtpd during the second half of the calendar year.

Norman Williams, President and CEO, commented:

"The primary focus during the second quarter was on the development meters necessary to achieve our longer term mine plan of 1,250 mtpd, with a balance of development and stoping mineralization. As a result, mill feed grade was less than guidance for the period. This lower grade is a result of increased processing of low grade development ore while we continue to push underground headings in preparation for sustainable mining at 1,250 mtpd. We expect this trend to continue until the end of the second quarter when are expected to improve. Completing the primary and secondary development now is necessary to support the higher mining rate in the long term mine plan.

"At the end of the period mill throughput averaged 910 mtpd, for operational ran. Only minor plant modifications remain to push for our target throughput of 1,250 mtpd. These modifications will be made over the coming months in time for sustained production from the mine."

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 increase mine and mill production to 1,250 mtpd by mid calendar 2017. This initial expansion has been fully funded through CEII's investment. Rambler will also continue advancing engineering studies on ore pre-concentration (DMS) and shaft rehabilitation with a view to further increase production to 2,000 mtpd at the Ming Mine. In addition, Rambler has initiated a detailed study at the mill with a goal to increase the gold recovery and production rate in the copper concentrator.

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.
