Silver Bear Vertikalny and Mangazeisky North Resource Revision
22 Juni 2020 - 1:53PM
Silver Bear Resources Plc (“Silver Bear” or the “Company”) (TSX:
SBR) announces that it has now received a draft report from Wardell
Armstrong (Moscow) that provides a review of the Company’s current
mineral resources, as well as draft revised mine and processing
plans, for its Vertikalny and Mangazeisky North deposits (“Draft WA
Report”). Silver Bear had previously disclosed that it had engaged
Wardell Armstrong (Moscow) to conduct this review of the mineral
resources as well as revised mine and processing plans for these
deposits.
The Draft WA Report presents a potential
material change to the current mineral resources at these deposits.
Given the potential material changes to the mineral resource
estimates for both Vertikalny and Mangazeisky North deposits and
the scope of the project outlined in the Draft WA Report, the
Company’s August 2017 NI 43-101 technical report containing the
current resource update and accompanying Vertikalny feasibility
study and Mangazeisky North pre-feasibility study, should no longer
be relied upon and are withdrawn by the Company.
Finalisation of the Draft WA Report is dependent
on Wardell Armstrong conducting a site visit to the Company’s
mining operations in Yakutsk, Russia. Owing to government-mandated
COVID-19 restrictions, the site visit has been delayed for an
indefinite period of time.
On the basis of the work that has been completed
to date by Wardell Armstrong (Moscow), in comparison to the
previous mineral resource estimate performed by Tetra Tech (UK) and
last filed on SEDAR in August 2017 and further updated in press
release dated 21 December 2017, the Company can relay with
reasonable confidence that the following changes can be expected
when the report and resource statement are finalized:
- Vertikalny open pit measured and
indicated resource at a 200 g/t Ag cut-off grade may be reduced by
about 3% of the silver grade and 29% of tonnes, taking into account
the total mined-out tonnes as of May 2019;
- Vertikalny underground measured and
indicated resource at a 300 g/t Ag cut-off grade may be decreased
by 24% of the silver grade and the tonnes by 56% due to adjustment
of open pit/underground optimisation parameters and/or
re-interpretation of the mineralisation; and
- Mangazeisky North measured and
indicated resources at a 200 g/t Ag cut-off grade may be downgraded
to inferred largely due to a lack of definition of ore types on the
deposit supported by testwork. Contained in-situ silver for
Mangazeisky deposit as a whole may be reduced by 28% although the
average silver grade may be increased by 14%. This is due to
application of constraining wireframes and search parameters more
appropriate to the style of mineralization. While the new model is
expected to be more conservative in terms of ore tonnes it will
provide better consistency in distribution of silver grade and
hence the grade increase.
The anticipated reduction of the measured and
indicated resources at both Vertikalny and Mangazeisky North
deposits is expected to result in a material change to the project
economics. The Company plans to release the final Wardell Armstrong
review and analysis of its impact on the project along with the
Company’s actions and plans for the project’s development as soon
as the site visit is completed and the Draft WA Report delivered in
final form.
Vadim Ilchuk, President and Chief Executive
Officer, commented, “The Draft WA Report is intended to describe
our evolving comprehension of our resources. It has become apparent
during the ramp-up to commercial production that the Vertikalny
measured and indicated resource grade and tonnage were not fully
realized in the ore that was mined and processed.
Accordingly, the Company and team implemented many cost,
processing and mining optimisations to offset the deficit,
including reduction in the Company’s corporate structure and
services, reduction in reagent consumption, fuel and energy costs
savings, implementation of the Merrill Crowe process, in-house
blasting and drilling work and adding the X-Ray transmission
processing technology to our processing line. Notable too is our
continued exploration program, where budgets allow, of the many
targets we have within the Mangazeisky licence.”

About Silver Bear Silver Bear
(TSX: SBR) is focused on the development of its wholly-owned
Mangazeisky Silver Project, covering a licence area of
approximately 570 km2 that includes the high-grade Vertikalny
deposit (amongst the highest-grade silver deposits in the world),
located 400 km north of Yakutsk in the Republic of Sakha within the
Russian Federation. As of April 2018, the Company attained first
silver production as a result of commissioning activities and on 1
July 2019 the Company achieved full commercial production.

Cautionary Notes
This release and subsequent oral statements made
by and on behalf of the Company may contain forward-looking
statements, which reflect management's expectations. Wherever
possible, words such as "intends", "expects", "scheduled",
"estimates", "anticipates", "believes" and similar expressions or
statements that certain actions, events or results "may", "could",
"would", "might" or "will" be taken, occur or be achieved, have
been used to identify these forward-looking statements. Although
the forward-looking statements contained in this release reflect
management's current beliefs based upon information currently
available to management and based upon what management believes to
be reasonable assumptions, the Company cannot be certain that
actual results will be consistent with these forward-looking
statements. A number of factors could cause events and achievements
to differ materially from the results expressed or implied in the
forward-looking statements. Such risk factors include, but are not
limited, to the risk factors identified by the Company in its
continuous disclosure filings filed from time to time on SEDAR.
These factors should be considered carefully and prospective
investors should not place undue reliance on the forward-looking
statements. Forward-looking statements necessarily involve
significant known and unknown risks, assumptions and uncertainties
that may cause the Company’s actual results, events, prospects and
opportunities to differ materially from those expressed or implied
by such forward-looking statements. Although the Company has
attempted to identify important risks and factors that could cause
actual actions, events or results to differ materially from those
described in forward-looking statements, there may be other factors
and risks that cause actions, events or results not to be as
anticipated, estimated or intended. There can be no assurance that
forward-looking statements will prove to be accurate, as actual
results and future events could differ materially from those
anticipated in such statements. Accordingly, prospective investors
should not place undue reliance on forward-looking statements.
These forward-looking statements are made as of the date of this
release, and the Company assumes no obligation to update or revise
them to reflect new events or circumstances, unless otherwise
required by law.
This release also contains references to
estimates of Mineral Resources. The estimation of Mineral Resources
is inherently uncertain and involves subjective judgments about
many relevant factors. Mineral Resources that are not Mineral
Reserves do not have demonstrated economic viability. The accuracy
of any such estimates is a function of the quantity and quality of
available data, and of the assumptions made and judgments used in
engineering and geological interpretation, which may prove to be
unreliable and depend, to a certain extent, upon the analysis of
drilling results and statistical inferences that may ultimately
prove to be inaccurate. Mineral Resource estimates may have to be
re-estimated based on, among other things: (i) fluctuations in
silver or other mineral prices; (ii) results of drilling; (iii)
results of metallurgical testing and other studies; (iv) changes to
proposed mining operations, including dilution; (v) the evaluation
of mine plans subsequent to the date of any estimates; and (vi) the
possible failure to receive required permits, approvals and
licences.
