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.

*Mineral Resource Notes
Mineral Resources are not Mineral Reserves and have not
demonstrated economic viability. All figures are rounded to reflect
the accuracy of the estimate. Cut--off grades of 1.0 % copper for
the massive sulphides, 1.25 grammes per tonne gold for any gold
zones and 1.0 % copper for the stringer sulphides have been used in
the estimate.
Cut--offs are based on an NSR model and forecast long term metal
prices of USD$2.99 per pound copper, USD$1,300 per ounce gold and
USD$17.00 per ounce silver with a long-term USD/CDN FX rate of
1:0.80. Resources are inclusive of reserves.
**Mineral Reserve Notes
All figures are rounded to reflect the accuracy of the estimate;
numbers may not total due to this rounding. This reserve statement
reflects changes to reserves based on depletion due to mining over
the 2018 to 2020 calendar years and through 31 March 2021. The NSR
for the reserve material was calculated using an all-in cost of
USD$72 per tonne of ore milled.
Long term metal prices used were USD$2.99 per pound copper,
USD$1300 per ounce gold and USD$17.00 per ounce silver with a
long-term USD/CDN FX rate of 1:0.80.
The procedures used for the Mineral Resource and Reserve
estimations are consistent with the Canadian Institute of Mining
and Metallurgy ('CIMM') (2014) best practices.
The effective date for the depleted Mineral Resource Estimate is
March 31, 2021. The effective date for the depleted Mineral Reserve
Estimate is March 31, 2021.

APPENDIX 2 - 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
"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
