Update to 2022 Underground Diamond Drill Program
25 April, 2022
Rambler Continues to Intersect High Copper Grades in the Lower Footwall and Ming North Zones
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 provide an update to its 2022 underground diamond drill program at the Ming Copper-Gold Mine, Baie Verte, Newfoundland and Labrador, Canada. This is the first release of all data presented in this announcement.
Rambler has drilled over 5,600 meters year to date in 2022. The 2022 program is providing definition drilling in the Lower Footwall Zone ("LFZ") and is drill testing the recently discovered Jennings and LP East Zones. Additionally, further delineation drilling in the Ming North Zone ("MNZ") has been completed from the 795L down to the 830L.
Of note, holes R22-535-09 and R22-535-10 were extended 100 meters past the Jennings Zone and intersected copper mineralization of interest (see "New Discovery" intercepts below). This potential new zone of mineralization will be further drill tested once other priority work is completed.

The next phase of the drill program will be to continue to infill the planned LFZ stoping blocks identified in the 2024 mining plan, and to delimit the newly discovered Jennings and LP East Zones. These newly discovered zones are open in all directions and require drill hole definition to be put into the mining plan.
Toby Bradbury, President and CEO, commented:
"Rambler's diamond drill program has continued to demonstrate grade continuity in all drill holes through both the LFW and MNZ. With these new intercepts into the Indicated and Inferred portions of the MNZ resource, we are seeing encouraging results from the holes we have assayed to date. We are seeing better grades at depth, and expansion of the resource to the east. Once all results have been received and imported, and the data analyzed, we will report accordingly. Gold assays have been sent to a third party lab for results and will be reported once received. The higher grades seen with recent drilling and coupled with the easterly expansion of the zone is encouraging as it opens up the potential for this high-grade zone to become a larger portion of the mine production plan in the years to come."

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 (76 mm diameter). Rambler employs an Oriented Core tool which provides valuable information in terms of the orientation of mineralized stringers, dip and dip direction of structure, lithology and foliation for future modelling and geotechnical interpretation. 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. Sample pulps are later shipped, using commercial freight services, to independent laboratories for gold assaying.
Tim Sanford, P.Eng., is the Qualified Person responsible for the technical content of this release and has reviewed and approved it accordingly. Mr. Sanford is an employee of Rambler Metals and Mining Canada Limited.

APPENDIX 1 - Glossary of Select Geological and Mining Terms
Term Definition
''Au'' gold
"Ag" silver
''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
''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
