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:

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
