Rambler Continues Strong Performance in H2 2019 and FY 2019

And Provides Guidance for Full Year 2020

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 ended December 31, 2019 it achieved its highest annual saleable copper and gold production since FY2014, at 5,299 tonnes and 4,887 ounces respectively. These figures represent 27% and 17% increases over FY2018 saleable copper and gold respectively. H2 2019 saleable copper and gold totalled 2,675 tonnes and 2,438 ounces, representing a 2% increase and 0.5% decrease compared to H1 2019, and 12% and 5% increases over the same period a year ago respectively. The 2019 annual performance was supported by a 12% increase in mill throughput and 16% and 5% increases in copper and gold head grades compared to the previous year.

H2 2019 and Full Year 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 H2 2019 vs H2 2018 (1,061 dry tonnes per day vs 1,014 dry tonnes per day), representing a 5% improvement, and in the full year-over-year figures (1,113 dry tonnes per day vs 998 dry tonnes per day), representing a 12% improvement.

o Consistently higher rate of copper contained in ore mined in H2 2019 vs H2 2018 (16.3 tonnes per day vs 14.0 tonnes per day), representing a 16% improvement, and in the full year-over-year amounts (16.1 tonnes per day vs 12.4 tonnes per day), representing a 30% improvement.

·; During H2 2019, the Nugget Pond copper and gold milling facility processed 195,208 dmt at a feed grade of 1.54% copper and 0.59 grams per tonne gold versus 186,571 tonnes at a feed grade of 1.38% copper and 0.60 grams per tonne gold in H2 2018. For the full year, the plant processed 406,298 dmt at feed grades of 1.45% copper and 0.59 grams per tonne gold.

·; Recovery of metal to concentrate was 92.8% and 74.0% for copper and gold respectively in H2 2019, nearly unchanged from H2 2018 despite higher throughput. For the full year, metal recoveries were 93.9% and 71.4% for copper and gold respectively.

·; During H2 2019, the operation produced 9,702 tonnes of concentrate containing saleable metal of 2,675 tonnes of copper and 2,438 ounces of gold. Saleable tonnes of copper increased 12% from H2 2018 and saleable ounces of gold increased 5% from H2 2018. During 2019, the operation produced 19,924 tonnes of concentrate containing saleable metal of 5,299 tonnes of copper and 4,887 ounces of gold respectively. These figures represent 27% and 17% increases over F2018 saleable copper and gold.

Andre Booyzen, President and CEO, commented:

"The overall improved performance in 2019 has demonstrated the effectiveness of our management changes, and our focus on continuous improvement that was started in mid 2018 and still continues. All of our staff and associates are absolutely committed and determined to continue to produce safely while meeting our production targets."

"Despite some challenging ground conditions encountered in September 2019, we managed to set a new record for our monthly development rate, which when sustained will support growing production at higher grades from more production stopes. Our efforts to develop our people and effect company-wide cultural changes has continued the positive momentum in our workforce. We are still seeing low staff turnover and low absenteeism. Our commitment to local recruitment and training remains, and we have recently stepped this up by utilising external consultants to assist us."

"We achieved our 2019 guidance tonnes of ore mined, copper grade and saleable copper produced. However lower than expected gold grades resulted in less than forecast saleable gold ounces. We expect to see similar lower gold grades in the areas of the ore body we are planning to mine in 2020, and our guidance reflects this.

"During 2019, we completed work ahead of schedule on the new tailings facility and we have been depositing tailings at Camp Pond under manual control since July 2019. The tailings project included some critical control components necessary to sustain milling rates in excess of 1,400 dry tonnes per day and these were in place and operational by the end of August 2019. In the fourth quarter we replaced some key mining equipment that had reached the end of its useful life, as well as added to our underground fleet to enable longer hauls as we mine deeper. We also made some improvements to our plant, enabling us to ramp up throughput as mining rates increase. We also recommissioned our Dense Media Separation (DMS) plant, ready to process lower grade ore, mostly coming from on-ore mine development. All in all, 2019 was a positive year for the operations, and we look forward to building on the success we achieved."

2020 Production GUIDANCE

Andre Booyzen, President and CEO, commented:

"We demonstrated in 2019 that our operations are capable of reaching and exceeding our own throughput expectations. Our focus in 2020 will be on consistency and to keep building towards our ultimate target of 1,500 tonnes ore processed per day at 2% Copper grade. Productivity improvements in the mine have provided access to better grade material in both the Lower Footwall Zone and the Ming Massive Sulfide deposits, so now we are now turning our attention to increasing the tonnage and overall feed grade delivered to the mill.

2020 will be an exciting year of improvements and change, with the operation of the DMS plant to upgrade our lower grade ore and further improvements in our plant feed rates. Although this is not new territory for us, we need to consolidate our efforts and successes to continue our longer-term journey towards increased, but stable and consistent production and growth at the operation.

Our guidance targets for 2020 are highlighted in Table 3 below. We are forecasting improved performance and output in all areas over the course of the year and our current focus is on sustaining mine and mill production at over 1,350 metric tonnes per day. By the beginning of Q3 2020 we expect to be consistently milling above 1,400 tonnes per day at 2% copper grade, whilst still targeting our ultimate goal of 1,500 tonnes per day."
