Rambler Discovers New High-Grade Mineralization in the Lower Footwall Zone

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 provides an update to its on-going underground diamond drill program at the Ming Copper-Gold Mine, Baie Verte, Newfoundland and Labrador, Canada.

The current 510L drill program is testing a previous intersection in an under-drilled area outside of the "low-grade" shell of the interpreted Lower Footwall Zone ("LFZ"). Following an initial discovery hole (R21-510-01) returning 42 meters grading greater than 2% copper, six more holes were added to further define the extent of the mineralization. See Figure 1 for a plan view of the new drilling, Figure 2 for a drill section and Table 1 for complete new assay results. Going forward, this new zone east of the main LFZ zone has been named the LP East zone ("LPEZ").

Toby Bradbury, President and CEO, commented:

"The continued success of our exploration and infill drilling programs provides additional confidence in the resource we have in the ground at the Ming Mine. The diamond drilling completed throughout 2021 has now infilled all production areas for the next 18 months, giving us some breathing room to test exploration targets in addition to continuing the on-going infill drill program.

It is particularly important that the new discovery described in this release, the LP East zone, while lying outside the previously interpreted high-grade shell of the LFZ, is very close to current workings. The discovery opens up new targets for exploration all along the currently modelled zone, both up dip and down dip. The LP East zone has the potential to add flexibility and optionality to the near-term production profile of the mine for minimal capital development time and cost. 

This relatively limited drilling program further highlights the exploration potential that exists at Ming Mine.  We have a series of further exploration targets which we aim to advance in 2022."

The 510-585L LP East Zone

To date, the LPEZ  program has discovered and defined a new mineralized zone with a vertical height of approximately 100 meters ("m") and a horizontal width of approximately 80 m. The recent drilling has shown significant potential to continue expanding the zone both up and down plunge. R21-510-07 is particularly encouraging as it demonstrates the new potential for mineralization outside of even the low-grade limit of the modelled LFZ resource shape. Rambler is excited by these initial drill results and will continue to drill this zone and explore for others like it during 2022.

The drilling program for the Ming Mine is being run under the supervision of Mark Ross, P. Geo., who is a qualified person as defined by NI43-101.

All drilling reported in this release was completed by an independent contractor with BQ-sized diamond core (36.5 mm diameter). Logging and sampling of diamond drill core is completed on site by Rambler geologists who ship samples daily, using Rambler vehicles and drivers, to the Company's own laboratory for copper assay by standard x-ray fluorescence ("XRF") methodology. As part of its QA/QC program 10% of all samples processed are sent for duplicate analysis at an accredited external lab using standard XRF methodologies. >5% of all assays complete by the Nugget Pond Lab are sent to external labs for third party confirmation.

 ''concentrate''                              in general, the saleable product resulting from crushing and grinding of mined ore in a processing plant along with concentration to remove impurities. Base metal operations can produce copper, lead and/or zinc concentrates

''Cu''                                                 copper

''cut-off''                                        lowest grade of mineralised material considered economic, used in the calculation of ore reserves. Also used in reserve estimation, meaning all material higher than the given grade

''down plunge''                             the direction within a rock mass indicated by linear features such as mineral lineation, fold axes or direction of maximum strain caused by deformation

''Footwall Zone'' or ''LFZ''   a mineralised zone beneath a geological feature such as a fault, another mineralised zone or bed

''grade''                                            relative quantity or the percentage of ore mineral or metal content in an ore body

"Inferred Mineral Resource"  that part of a Mineral Resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity. It has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.

''Indicated Mineral Resource''  that part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. The locations are too widely or inappropriately spaced to confirm geological and/or grade continuity but are spaced closely enough for continuity to be assumed ''massive sulphide'' occurrence of a concentrated mass of sulfide mineral such as pyrite, sphalerite or chalcopyrite in one place, as opposed to their being disseminated or occurring in vein

''Measured Mineral Resource''     that part of a Mineral Resource for which quantity, grade or quality, densities, shape, and physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced

''Mineral Resource''   a concentration or occurrence of material of intrinsic economic interest in or on the Earth's crust in such form that there are reasonable prospects for eventual economic extraction. Mineral resources are sub-divided, in order of increasing confidence, into Inferred, Indicated and Measured categories

''mineralised''   containing or impregnated with minerals

''National Instrument 43-101''  provides standards of disclosure for mineral projects in Canada. It is a legal requirement in Canada for all oral and written disclosure of scientific or technical information on mineral deposits

 ''ore''                                                rock that can be mined and processed at a profit

 ''oz''                                                  troy ounce (=31.103 grammes)

''Probable Mineral Reserves''   measured and/or indicated mineral resources which are not yet proven, but where technical economic studies show that extraction is justifiable at the time of the determination and under specific economic conditions

''Proven Mineral Reserves''   measured mineral resources, where technical economic studies show that extraction is justifiable at the time of the determination and under specific economic conditions

''reserve''                                     that part of a resource that can be mined at a profit under reasonably expected economic conditions

''resource''                                     mineralised body for which there is sufficient sampling information and geological understanding to outline a deposit of potential economic merit

 ''stringer''  a thin, discontinuous mineral vein or rock layer

''sulphide''   a mineral containing sulphur in its non-oxidised form

''t''  a metric tonne
