Rambler Hits Record Throughput for 2018

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 pleased to announce that for the fiscal year ending December 31, 2018 it achieved record throughput by processing 364,176 tonnes of ore from the Ming Mine through the Nugget Pond copper and gold milling facility. This is the second consecutive year that the Company has set a new throughput record.

2018 Production Summary

· For the fiscal year the Nugget Pond copper and gold milling facility achieved record throughput. The facility processed 364,176 dry tonnes at a feed grade of 1.24% copper and 0.57 grammes per tonne gold for the 2018 fiscal year. Annual mill throughput averaged 1,108 dry tonnes per day with a monthly peak of 1,228 dry tonnes per day in April. Into 2019, to match increased mine output, the mill continues to push throughput and has recently achieved a one-day record throughput of 1,492 dry tonnes per day. This is another significant milestone for the Company and confirms that incremental 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 96.3% and 70.7% for copper and gold respectively for the year. For the full year the operation produced 15,525 tonnes of concentrate containing saleable metal of 4,187 tonnes of copper and 4,189 ounces of gold.

Andre Booyzen, President and CEO, commented:

"2018 was a banner year for operations in several areas, including year-over-year improvements in mine output, mill throughput, concentrate production, and metal recoveries. This growth is due to the efforts of all of our employees and contractors, who have continued to keep "Safe Production" at the forefront of everything they do."

"While the mine averaged 998 tonnes of ore per calendar day from the underground, the mill averaged 1,108 tonnes of ore per operating day and hit single-day peak production in 2018 as high as 1,395 dry tonnes per day."

"The completion of the surface ventilation project and the continuation of the Business Improvement Initiative that was started in June 2018 has resulted in improved production metrics from the mine operation (see Table 1 below). These improved KPI's from the mine operation have in turn resulted in better ore blending opportunities for the mill feed, which has positively impacted both throughput and metal recoveries. Additionally, the processing operations group continues to de-bottleneck the copper concentrator processing circuit to accommodate the increased production from the mine."

"Given the productivity improvements in the mine operation, which has 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 and returning the Company to positive cash flows during a time that has seen significant run up and positive outlook on long term copper price forecasts."

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.
