Rambler Updates Mineral Resources for the Ming Copper-Gold Mine
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 announces an update to copper, gold and silver contained in estimated Mineral Resources at the Ming Copper-Gold Mine, located in Eastern Canada.
A depleted Mineral Reserve is also reported. This Mineral Reserve is based on mining depletion from the previous estimate which had an effective date of 31 December 2019. Both the depleted resource and reserve estimates have effective dates of 31 March 2021.
BACKGROUND
-- Throughout 2020, due to financial constraints, limited mining took place at Ming Mine, with respect to both production and development.
-- Rambler limited all expenditures including diamond drilling in 2020. During this period, reconciliation of mined blocks, lithological modelling and resource targeting was carried out.
-- Rambler has resumed underground diamond drilling, and plans to drill more than 15,000m in 2021. The drilling will be used to update the global resource model, with a planned update to the mining reserve to be delivered in 2022.
-- As well as updating the global resource model, specific objectives in 2021 are to:
o In-fill drill for mine design and planning;
o Convert portions of the inferred resource to an indicated or measured confidence category; and
o Target prospective areas identified during the 2019 drilling campaign and 2020 model review.
RESOURCE SUMMARY
-- The updated resource estimate includes 24.143 million tonnes of Measured and Indicated Resources grading 1.69% copper and 0.32 grammes per tonne ("g/t") gold, containing 900 million pounds (408,199 tonnes) of copper and 251 thousand ounces of gold at 1% copper cut-off. This represents a 6% increase in contained copper and 5% increase in contained gold relative to the previous resource estimate declared in 2017, after mining depletion.
-- The Inferred Mineral Resources remain at 5.023 million tonnes grading 1.89% copper and 0.41 grammes per tonne gold containing 209 million pounds of copper and 66 thousand ounces of gold at 1% copper cut-off.
-- All zones remain open for extension with further drilling, especially down dip from the current resource.
-- Details of the new Mineral Resource estimate by zone appear in Appendix 1.

The procedures used for the Mineral Resource estimation are consistent with the Canadian Institute of Mining and Metallurgy ('CIMM') (2014) best practices. See Mineral Resource note below for additional disclosures.
Dr Toby Bradbury, President and CEO, commented:
"It is encouraging to note that the overall high-grade copper Measured and Indicated resource endowment of the Ming Mine remains over 405,000 tonnes of copper, with an additional 95,000 tonnes of copper in the Inferred category.
"Our Mineral Reserve statistics, which will be updated in 2022 to incorporate the latest 2021 drill data, are themselves conservative, being based on USD$2.99 per pound copper, significantly less than current copper price.
"The diamond drilling program that resumed in Q1 2021 and continues is providing confirmatory data which supports the modelling of the resources. The in-fill drilling is being conducted in parallel with the redevelopment of the Ming Mine through 2021 and is a key element of risk mitigation for the future as we confirm our short and longer-term target areas for mining.
"All zones of mineralisation remain open at depth and we are pursuing well identified targets with a commitment to the proper development and exploration of the mine.
"The Ming Mine remains a world-class resource in a first-rate jurisdiction with potential to be further expanded. This mine, together with the Little Deer and Whalesback properties provide an exciting long-life mining platform for Rambler."
Lower Footwall Zone
The Lower Footwall Zone is the area currently being developed as the cornerstone source of future mined tonnes. This zone has potential to flex depending on the cut-off grade employed as shown in Table 2 below.

Including the Massive Sulphide deposits, at a 1.5% copper cut-off, the entire measured and indicated mineral resource estimate consists of 11.581 million tonnes of material grading 2.21% copper and 0.49 grammes per tonne gold, containing 565 million pounds of copper and 181 thousand ounces of gold. This material will form the basis of a new NI43-101 compliant life of mine (LOM) plan for the Ming Mine that is planned for completion in 2022, building on the drill data from the 2021 program.
A comparison of the new Mineral Resource Estimate to the previously released Mineral Resource Estimate, effective date September 7, 2017, is shown in Table 3 below.

"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
"Proved 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
