Exploration Update at Ming Mine Operation
4 June 2015
Rambler Provides Exploration Update at its Ming Mine Operation
With New Drilling Extending the High Grade Copper and Gold Zones
London, England & Baie Verte, Newfoundland and Labrador -Rambler Metals and Mining plc, a Newfoundland copper and gold producer, explorer and developer (TSXV: RAB, AIM: RMM) ("Rambler" or "the Company") today provides an update on its exploration diamond drilling activities over the past nine months at the Ming Copper-Gold Mine, located in Newfoundland and Labrador, Canada.
HIGHLIGHTS - COPPER
· The Company completed 4,544 metres of diamond drilling in the 1807 Zone and has been successful in extending this high grade copper zone both down plunge and along strike. Table 1 below shows highlights of significant intersections.
· The deepest drill hole completed to date has extended the 1807 resource model an estimated 100 metres below the deepest reserve level of 630L. Drilling along strike to the west has extended the zone an estimated 40 metres beyond previous plans. The newly defined mineralisation is being modeled for inclusion in the 2016 Fiscal Budget and pre-feasibility with the Lower Footwall Zone.
· Drilling has recently started defining a new area down plunge on the Ming North Zone ('MNZ'), below the historically mined 2,300 foot level. Assay results have confirmed the extension of the zone with copper and gold grading over a broad intersection. This area has not been previously included in the mine's resource or reserve estimates.
HIGHLIGHTS - GOLD
· 1,457 metres of diamond drilling has been completed on the 1806 and 1805 massive sulphide zones.
· New drilling intersected visible gold with grades ranging up to 18.32 grammes per tonne gold, 1.14 per cent copper and 41.61 grammes per tonne silver over 9.51 metres (core length), including intersections of 37.63 grammes per tonne gold, 1.64 per cent copper and 54.86 grammes per tonne silver over 3.82 metres. Table 2 below shows highlights of significant intersections.
· Drilling is ongoing to further define the extents of this new discovery.
Norman Williams, President and CEO, said,
"It is encouraging that all of the massive sulphide zones in the mine remain open at depth and have good potential for continued success under the exploration program. The massive sulphides currently being mined have been known to return some significant high grade intersections while production from these areas can produce good cash flow. Mining of these areas will continue throughout Fiscal 2016 and beyond, the planned increases in mill throughput will be made possible through the integration of Lower Footwall Zone material.
"The Phase 2 pre-feasibility will aim to combine the massive sulphide ore with a larger production base from the LFZ, thereby adding further production stability to the overall operation. Phase 2 expansion should demonstrate the long-term potential of the operation.
"The pre-feasibility is on schedule to be released before the middle of this calendar year and will outline a phased, low capital, approach for the project's expansion at 1,250 metric tonnes per day."
Extension of the 1807 Zone
The 1807 Zone has produced the majority of tonnes mined since first declaring commercial production in November 2012. Underground diamond drilling has extended the high grade copper zone along strike 40 metres to the west and 100 metres below the deepest planned development level at 630 metres.
A structural interpretation of the developed levels in this area has determined that a mine scale thrusting event has extended the 1807 Zone thirty to forty metres further west than previously defined. This northwest extension is of significantly higher grade and locally thicker than the current resource shape. Fiscal planning is underway and will include planning for this new area which will likely be developed during Q1 2016.
Table 1 below shows highlights of the significant intersections.
Extension of the Ming North Zone ('MNZ')
Recent drilling of the MNZ, approximately 50 metres below the historically mined 2,300 foot level, has confirmed the continuation of this ore zone at depth. While this area is not presently included in any resource shape the new drilling has intersected high grade copper in massive sulphides. Importantly, this drilling has also highlighted the presence of a broad stringer zone below the massive sulphides. The addition of this area could potentially increase the tonnes of reserve per vertical meters allowing for more efficient mining.
Surface exploration drilling in 2003 and 2005 intersected the Ming North Zone 620 metres down plunge of this new drilling, see Figure 1 below. Once the 2,450 foot level drill bay is extended, infill drilling will be completed with the hope that this material can be included in a future resource and reserve estimates. Further drilling and interpretation is ongoing to define the mining potential of this area.
Table 1 below shows highlights of the significant intersections from the drill program.

Gold Rich 1805 and 1806 Zones
The 1805 and 1806 Zones are gold rich massive sulphides that occur on the mineralised hangingwall/footwall contact and exist laterally between the 1807 zone and the MNZ.
Drilling from ramp drill bays have determined that significant localised sulphide accumulations can occur adjacent to the 1807 ramp. Diamond drill assays from these zinc and copper rich sulphides have returned high grade gold associated with visible gold electrum.
More drilling is being planned to determine the extent and mining potential of the new sulphides.
Table 2 below shows highlights of the significant intersections from the drill program.

Rambler's 2015 fiscal diamond drilling program was designed to add comparable grade material to the resource and reserve by extending ore zones both along strike and down plunge. The fiscal 2015 exploration program has been successful in:
· Further defining areas of high grade copper and gold near underground infrastructure. New mineralisation has been outlined further down plunge and to the west for the 1807 Zone.
· Extending the historically mined Ming North Zone ('MNZ') down plunge.
· Discovering new areas of gold rich massive sulphides in the 1806 and 1805 Zones.
Infilling the lateral gap between the 1807 Zone and the Ming South Zone with additional ore sources, such as the MNZ, 1806, and 1805 zones, should allow for more efficient and cost effective infrastructure design and production sequencing for the massive sulphides. An updated estimate of resources and reserves for the project is expected to be released mid-calendar year with the completion of the ongoing pre-feasibility evaluating the integration of Lower Footwall Zone material into the life of mine production stream through a staged, low capital, expansion program.
Analytical services for drill core assaying were completed by Eastern Analytical, an accredited assay laboratory in Springdale, Newfoundland and Labrador. The diamond drilling was completed by White Wulf Drilling based in Baie Verte, NL.
