Rambler Releases its Q3 and YTD Production Results

Productivity Improvement Initiative Continues

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 today provides production results for its Q3 and year-to-date ending 30 September 2018 ('Q3/18').

Q3/2018 Production Summary (REFER TO table 1)

· A total of 1,266 tonnes of saleable copper were recovered to concentrate in the quarter, a 29% increase over Q2/18 and a 26% increase over Q3/17. The quarterly production of saleable gold totalled 1,020 ounces, a 15% reduction from Q2/18 and 10% increase over Q3/17.

· Total mill throughput was 93,128 dry metric tonnes ('dmt'), a decrease of 2% compared to Q2/18 and a 17% increase over Q3/17. Average daily throughput at the mill for the quarter was 1,103 dmt per operating day.

· Copper feed grade for the quarter was 1.46% with a gold grade of 0.54 g/t. The copper grade represents a 30% uplift over Q2/18 and a 5% uplift over Q3/17. Average recoveries to concentrate for the quarter were: 97.3% for copper and 71.9% for gold, both of which represent increases over Q2/18 and Q3/17 performances. Concentrate grade produced for the quarter were 29.4% and 8.1 g/t for copper and gold respectively.

· A number of significant milestones at both the mine and the mill were achieved during the quarter.

o Mine development (excluding post-pillar-cut-and-fill ('PPCF') advance) in the quarter totalled 807 meters, representing a 5.4% increase compared to Q2/18 and a 40.3% increase over Q1/18. This reflects the improvements in productivity that have been embedded in the operation (see comment below) and the decision to convert the LFZ Block 1 mineral reserves from PPCF to longhole mining methods. This is allowing the development teams to focus on creating new ramps and ore access headings with the goal of improving the developed state of the mine and reducing overall mining costs.

o Longhole production drilling meters and longhole tonnes blasted increased by 60% and 74% respectively in Q3/18 compared to Q2/18, reflective of the increased focus on stope access development in the mine.

o At the plant, copper and gold recovered to concentrate increased quarter over quarter and year-to-date. The improved gold recovery of 69.6% year-to-date, a 15% increase over the same period in 2017 is a testament to the continuous focus by the mill team on recovery improvements.

Norman Williams, President and CEO, commented:

 "As noted in June, the Company commenced a productivity improvement initiative in the mine, with assistance from a third-party consultant, aimed at resolving mine production bottlenecks and increasing mill feed. The twenty-four week initiative is focused on productivity and efficiency improvements in three main areas: mine planning, mine operations and mine mobile equipment maintenance. The commitment of the project is to return the mine to profitability and positive cash flow at the nominal 1,250 dry tonnes per day processing rate.

"High level targets of the project include mining and hauling 1,250 dry tonnes per day ore at a minimum of 1.4% copper grade, delivering at least 18 tonnes copper per day in ore to the plant while also hauling 500 tonnes per day waste. A combined total of 1,750 dry tonnes per day of material movement for the mine.

"As the Company continues embedding change at the operations, productivity improvements are anticipated to support achievement of sustained production targets. During week 19 and 20 of the 24 week project (October 5-19, 2018), the following accomplishments were being realized:

· An average of 1,221 dry tonnes per day of ore was hauled to the surface grading 1.23% copper, for an average of 15 tonnes/day of contained copper.

· Over the same period, an average of 647 dry tonnes per day of waste material was mined and moved to a permanent storage location versus the 500 dry tonnes per day target.

· A record of 26 development rounds were blasted both weeks, totalling 182 meters of advance.

"Sustaining these production levels over the long term requires increasing the development rate from the current level to an average of 30-35 rounds per week. This uplift will be realized by a combination of increasing the number of development headings available each week, reducing the cycle time of the drill-blast-load-haul cycle, and cross training critical mining skills among the staff to allow key positions to be manned each day.

"Once again, the continued improvements over the first 20 weeks of the 24 week project are due to the commitment of our employees, their high rate of learning and their focussed innovation. What is critical is that we are working smarter while maintaining our focus on safety. On behalf of myself, and the entire Board, a sincere thank-you to all of our employees and contractors for your outstanding efforts."

Q3 2018 PRODUCTION SUMMARY

Table 1 - Quarterly and Year-to-Date Production Results

(See Note 1 below)

As of the date of this release, the mine is now developing on 10 headings in two areas of the underground mine (Ming Massive Sulfides (MMS) and Lower Footwall Zone (LFZ)). Ore production is planned from 2 high grade MMS longhole stopes and 2 longhole stopes in the LFZ. Additionally, post-pillar cut and fill production in the LFZ will continue to supplement longhole ore feed as required. With the on-going productivity improvement initiatives now embedded at the operation, ore production for Q3 is forecasted to be sustained at 1,250 mtpd and with average grades between 1.25-1.35% copper. As described in the NI43-101 Technical Report released in March 2018, copper grades are anticipated to improve with depth and continue increasing over the next 4 years reaching the reserve average grade of 1.71% in 2022.
