Rambler Sets New Benchmarks for Output in Q2 and H1 2019

London, England - Newfoundland and Labrador, Canada - Rambler Metals and Mining plc (AIM: RMM) ("Rambler" or the "Company"), a copper and gold producer, explorer, and developer, is again pleased to announce that for the fiscal quarter ending June 30, 2019 it achieved record throughput by processing 112,679 tonnes of ore from the Ming Mine through the Nugget Pond copper and gold milling facility. This supported a 45% increase in saleable copper produced in concentrate and 10% increase in saleable gold produced in concentrate relative to the same year-ago quarter. Additionally, first half (H1) 2019 record throughput of 211,090 tonnes of ore from the Ming Mine and through the Nugget Pond copper and gold milling facility has supported a 46% increase in saleable copper produced in concentrate and 32% increase in saleable gold produced in concentrate relative to the first half of 2018.

Q2 2019 Production Summary

·; The mining process improvement program begun in mid-2018 and executive management changes since then have resulted in:

o Consistently higher ore production rate in Q2 2019 vs Q2 2018 (1,239 dry tonnes per day vs 1,036 dry tonnes per day), representing a 20% improvement.

o Consistently higher rate of copper contained in ore produced in Q2 2019 vs Q2 2018 (17.2 dry tonnes per day vs 11.7 dry tonnes per day), representing a 47% improvement.

o Consistently higher development rounds per week - 24 per week in Q2 2019 versus 23 per week in Q2 2018, representing a 4% improvement. While total development rates have not changed significantly quarter over quarter, it is important to note that all of the current development is dedicated to providing ramp and level accesses to inexpensive long-hole production sources of ore, while in Q2 2018, 6 rounds per week were dedicated to expensive cut and fill mining ore sources.

·; For the fiscal quarter ending June 30, 2019 the Nugget Pond copper and gold milling facility achieved record throughput. The facility processed 112,679 dmt at a feed grade of 1.40% copper and 0.60 grammes per tonne gold during Q2 2019 versus 94,589 tonnes at a feed grade of 1.12% copper and 0.63 grammes per tonne gold in Q2 2018. Daily production during the quarter averaged 1,309 dry tonnes per day with a monthly peak of 1,339 dry tonnes per day in June. On July 22, the mill achieved a new one-day record throughput of 1,493 dry tonnes per day. This again confirms that the mill improvements will allow the facility to produce at a sustained rate at or greater than 1,250 dry tonnes per day.

·; Recovery of metal to concentrate was 93.7% and 68.4% for copper and gold respectively for the quarter, nearly unchanged from Q2 2018 despite higher throughput.

·; During the quarter, the operation produced 5,425 tonnes of concentrate containing saleable metal of 1,417 tonnes of copper and 1,321 ounces of gold. Saleable tonnes of copper increased 45% from Q2 2018 and ounces of gold increased 10% from Q2 2018.

Andre Booyzen, President and CEO, commented:

"This last quarter's mine and mill performance has demonstrated effectiveness of the focus on continuous improvements that were started in late 2018 and still continue. Our staff and contractors are focussed on producing safely and exceeding production targets."

"We will keep improving mining production and the average grade of ore produced so that saleable copper production continues to increase. Our efforts with people and culture has brought positive momentum to our workforce with low absenteeism and low staff turnover now aiding production. A commitment to local recruitment and training has resulted in a stable and committed workforce."

"We have completed work ahead of schedule on our new tailings facility and are depositing tailings at Camp Pond under manual control as of July 18. The tailings project included some critical control components necessary to sustain milling rates in excess of 1,400 dry tonnes per day and these will be in place and operational by August 31. We have also committed to replacing some key mining equipment that has reached the end of their useful life, as well as adding to our underground fleet to enable longer hauls as we mine deeper.

2019 Production GUIDANCE

Andre Booyzen, President and CEO, commented:

"We have demonstrated over the first half of the year that our operations are capable of reaching and exceeding our own throughput expectations. Given the productivity improvements in the mine, which have provided access to better grade material in both the Lower Footwall Zone and the Ming Massive Sulfide deposits, we are now turning our attention to increasing the overall feed grade delivered to the mill.

The remainder of 2019 will be an exciting time for us with plans in place to upgrade our lower grade ore and further improve mill feed rates. This will start us on our longer-term journey towards expanding to 2,000 ore tonnes milled per day at much higher grades.

Our progress against guidance targets for 2019 is highlighted in Table 3 below. All targets are on track except for gold grade and saleable gold, both of which will be assisted by a focus on achieving increased production from the high gold grade massive sulfide orebodies in the second half of 2019."

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.

Following the completion of its recent productivity improvement initiative Rambler's focus is on sustaining mine and mill production at 1,250 metric tonnes per day. With a return to profitability and positive cash flow, Rambler will continue advancing Phase III engineering studies with a view to further increase production to 2,000 dry tonnes per day 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 listed in London under AIM:RMM.
