 Rambler Intersects 102 Meters of 1.65% Copper

Including 35.8 Meters of 2.59% Copper,

Extending Mineralization 550 m Down-dip of Current Mineral Resource

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 the second hole in its surface exploration program has intersected significant Lower Footwall Zone mineralization 200 meters deeper than the previous drill hole.

Exploration Update

· The diamond drill hole was drilled from surface to a depth of 1686 meters, intersecting continuous Lower Footwall Zone mineralization grading 1.65% Copper ('Cu') over 102 meters

· Highlights from drill hole RM17-25b include:

Lower Footwall Zone ('LFZ')

102.0 meters of 1.65% Cu (From 1481.0m to 1583.0m)

Including 35.8 meters of 2.59% Cu (From 1481.0m to 1516.0m) and

Including 27.0 meters of 1.98 % Cu (From 1556.0m to 1583.0m)

· The mineralized intersections in RM17-25b lie approximately 200 meters down dip from the 40 meters of 1.42% Cu intersected in the previous hole, RM17-25a (see press release of September 14, 2017 and figure 1).

· The abundance of cross cutting, barren mafic dykes in the deeper LFZ intercepts of RM17-25b has declined relative to their abundance in the previous surface hole and in the current LFZ mining areas further up-dip. This decline in abundance of internal waste leads to the longer, continuous intercept at depth.

Norman Williams, President and CEO, commented:

"This latest Lower Footwall Zone intersection from the surface diamond drilling program is the thickest continuous LFZ mineralization discovered on the property to date. In the past similar grades have been seen over narrower intervals, ranging from 40 to 70 meters, bounded by barren mafic dykes. In this latest drill hole these barren mafic dykes occupy less than 10% of the drill core, allowing for a much thicker mineralized area.

"With holes RM17-25a and 25b we have now extended the LFZ an additional 550 meters down-dip beyond any previous drilling. We believe we have clearly demonstrated that the LFZ mineralization does indeed continue beyond our defined mineral reserves and increases in grade and thickness with depth. We look forward to continuing this surface drill program further in the New Year following an evaluation of the information collected to date."

Lower Footwall Zone Surface Exploration

A directional surface drilling program was initiated in June 2017 to test the down plunge continuity of the Lower Footwall Zone and Ming South massive sulphide zone. The most recent hole, R17-25b, was turned off from the RM17-25a parent hole at a depth of 890 m utilizing Devico directional drilling. The hole penetrated the Upper Pacquet Harbour mafic sequence to a depth of 1379 meters, where it intersected the hanging wall/footwall horizon familiar in the Ming Mine. This horizon is the contact with the underlying Rambler rhyolite and is host to the deposit Rambler is currently mining, as well as the five other past producing ore bodies within the Rambler camp. Lower Footwall Zone chalcopyrite stringer mineralization was intersected below 1392 meters and was accompanied by increasing chlorite alteration. Grades returned from the entire LFZ encompassed 102.0 m of 1.65% Cu, including separate intercepts of 35.8 m of 2.59% Cu and 27.0 m of 1.98% Cu. The hole was completed to a total depth of 1686 meters.

Note 1: Results reported are accurate and reflective as of the date of release. The Company performs regular auditing and reconciliation reviews on its processes following which past results may be adjusted to reflect any changes. Core lengths can vary depending on the angle the drill hole intersects the mineralized body. True widths are estimate to range between 90-95% of core lengths.

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 the fall 2017. This initial expansion has been fully funded through CEII Mining'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.
