Tin bearing greisen alteration discovered
along flank of radiometric anomaly
LONDON, Nov. 22, 2018 /CNW/ - Meridian Mining SE (TSXV:
MNO) ("Meridian" or the "Company") today announces the discovery of
tin (Sn) bearing greisen altered granites within its Espigão
production and exploration tenements in Rondônia Brazil ("the Project"). Located on the flank
of a radiometric anomaly, the greisen-altered granites hosting
cassiterite were mapped and assayed, returning strong Sn grades.
This is the first discovery of greisen alteration and bedrock tin
mineralization on the Project, and was a result of the expanded
technical focus on the manganese and polymetallic potential of the
Project.
The highlights from the discovery are:
- Rock chip tin grades reported by XRF analysis at SGS
laboratories, Belo Horizonte:
-
- Sample BMRK00469 assayed 0.79% SnO2;
- Sample BMRK00470 assayed 0.33% SnO2;
- Sample BMRK00472 assayed 0.21% SnO2;
- Surface samples are located along the flank of a radiometric
boundary. Tin is known from drainage pan-concentrate samples
associated with the same anomaly to the east and south east, but
had not previously been traced to a source.
- The location conforms to the larger polymetallic system the
Company is mapping.
The greisen alteration was discovered during an exploration
traverse along the extension of the Antônio Gomes manganese trend.
The location is on the southern boundary of a radiometric anomaly,
marked by a coarse-grained granite (Figure 1, Figure 2; Figure 3).
The objective of the traverse was to investigate the possibility of
anomalous metals (either manganese, base or precious metals)
situated along the granite's southern flank.
Pitting and trenching are required to confirm the width of the
zone, with the micaceous greisen being recessively weathered. The
identification of tin mineralization along the radiometric boundary
zone provides a focal point in the search for additional bedrock
tin sources to the various cassiterite occurrences recognised in
the drainage systems of the Project area.
Mr. Clark, Interim CEO & President, states, "The discovery
of tin bearing greisen altered granites is a first for the Project
and a great result. The initiative shown by the Company's geology
and environmental team in walking the trend and discovering this
very interesting mineralisation is a positive result for the
Company's shareholders and supporters. I look forward to see how
this develops both locally and also within the larger polymetallic
system of the Project."
The rock chip samples have been analysed by an accredited SGS
Laboratory in Belo Horizonte,
Brazil. Samples are dried, crushed to 3 mm, homogenised,
then a split is pulverised to produce a pulp of 250 - 300 g with
95% passing 150 mesh. Submissions include certified references to
monitor laboratory performance, which have returned results within
the expected laboratory analytical error margins. Laboratory
protocols include blanks, duplicates and repeats. Oxides have been
analysed by lithium-borate fusion - XRF techniques (method code
XRF80B). Minor elements have been analysed by lithium metaborate
fusion and ICP-MS finish. Until dispatch, samples are stored in the
company's supervised stockpile yard or exploration office. The
samples are couriered to the assay laboratory. Pulps and rejects
are returned to the Company and archived. Surface stream anomalies
have been defined by a pan-concentrate program with positive gold
and cassiterite gold results cross-checked by mineralogical reports
at SGS Laboratories in Brasília. The drainage sampling is collected
in a 20 liter bucket of alluvium from the lower level of a stream
channel, and provides a qualitative indication of the presence of
metal sources in the catchment areas.

FORWARD-LOOKING STATEMENTS
Some statements in this news release contain forward-looking
information or forward-looking statements for the purposes of
applicable securities laws. These statements include, among others,
statements with respect to the Company's plans for exploration and
development of its properties and potential mineralization. These
statements address future events and conditions and, as such,
involve known and unknown risks, uncertainties and other factors,
which may cause the actual results, performance or achievements to
be materially different from any future results, performance or
achievements expressed or implied by the statements. Such risk
factors include, among others, failure to obtain regulatory
approvals, failure to complete anticipated transactions, the timing
and success of future exploration and development activities,
exploration and development risks, title matters, inability to
obtain any required third party consents, operating hazards, metal
prices, political and economic factors, competitive factors,
general economic conditions, relationships with strategic partners,
governmental regulation and supervision, seasonality, technological
change, industry practices and one-time events. In making the
forward-looking statements, the Company has applied several
material assumptions including, but not limited to, the assumptions
that: (1) the proposed exploration and development of mineral
projects will proceed as planned; (2) market fundamentals will
result in sustained metals and minerals prices and (3) any
additional financing needed will be available on reasonable terms.
The Company expressly disclaims any intention or obligation to
update or revise any forward-looking statements whether as a result
of new information, future events or otherwise except as otherwise
required by applicable securities legislation.
The Company cautions that it has not completed any feasibility
studies on any of its mineral properties, and no mineral reserve
estimate has been established. In particular, because the Company's
production decision relating to Meridian Mineraçao Jaburi S.A,
manganese project is not based upon a feasibility study of mineral
reserves, the economic and technical viability of the Espigão
manganese project has not been established.
The TSX Venture Exchange has neither approved nor disapproved
the contents of this news release. Neither TSX Venture Exchange nor
its Regulation Services Provider (as that term is defined in the
