Trevali Mining Corporation (“Trevali” or the “Company”)
(TSX: TV, BVL: TV; OTCQX: TREVF, Frankfurt: 4TI) announces
results from the 2019 exploration program at Rosh Pinah with a high
grade extension to WF3 identified to the South.
“We are encouraged by the results from the
exploration program at Rosh Pinah and the ability to keep
intersecting high grade zones at the Western Orefield and extending
the deposit further North,” commented Yan Bourassa, Vice-President
of Exploration and Mineral Resources at Trevali Mining. “The
continued ability to increase the Mineral Resource base at Rosh
Pinah and extending the deposit indicates the quality of the
orebody and demonstrates the team’s ability to support Trevali’s
long term strategy of growth at Rosh Pinah.”

2019 Exploration Strategy
During 2019, the exploration team has focused on
fully exploiting the wealth of historic data accumulated over 50
years of continuous mining, including by identifying in-mine
targets that were previously sporadically explored. Continued
system analysis and structural reinterpretation is helping to
improve the understanding of the Rosh Pinah mineralizing system and
assist with targeting. The Rosh Pinah mineralisation was long
thought to be hosted exclusively along a single horizon; however by
challenging these perceptions, new opportunities are being
identified.
In-Mine Exploration
The Western Orefield 3 (WF3), the largest single
zone within the Rosh Pinah mine, was previously considered closed
along strike to the South East. Following structural
reinterpretation, drillholes U3372 & U3373 were drilled to the
SE of existing resources, intersecting multiple zones of
polymetallic mineralisation.
U3373 returned 57.81m at 9.2% Zn 3.3% Pb 43.4g/t
Ag including 30.44 metres at 12.7% Zn, 5% Pb & 72.6g/t
Ag. This broad zone of high grade mineralisation was
hosted within barite and carbonated ore, a favorable mineralization
style for the plant characterized by high recoveries. This zone is
located at the contact between an arkose and a limestone horizon
with significant barite and carbonate replacement. The Zn
mineralisation is characterized by white-yellow colored Sphalerite
generally observed at the high grade Eastern and Southern
Orefields, the highest-grade mineralized zones within the Rosh
Pinah mine, but rarely observed within the Western Orefield
orebodies.
Exploration hole U3372 intersected 38.77 metres
at 9.5% Zn, 2.3% Pb, 12.8g/t Ag including 9.15 metres at
15.4% Zn, 5.2% Pb, 28.2g/t Ag. These holes are thought to
have intersected mineralisation within the hinge portion of a
synform fold. Structural remobilization is an important control on
the Rosh Pinah mineralization with folds noses and hinges being
associated with high grade zones.

https://www.globenewswire.com/NewsRoom/AttachmentNg/6887092c-ee26-4f7a-b4ea-c318daf8fff2
These holes demonstrate that there is great
potential for new high grade, polymetallic tonnes at Rosh Pinah.
This newly identified high grade zone remains open to the South
East and North West and will be the major target for 2020 Q1.
During 2019, several priority in-mine
exploration targets were identified which are being reassessed by
relogging and structural analysis. This Southern extension to WF3
was the first of the in-mine targets to be tested.
Indicated Infill Drilling
Ongoing indicated drilling targeting the center
of the WF3 has also continued to intersect good mineralisation.
U3351 multiple zones of broad mineralisation; 32.05 metres at 8.9%
Zn, 0.7% Pb, 10.65g/t Ag including 6 metres at 15.9%
Zn, 0.6% Pb, 10.8g/t Ag & 44.75 metres at 11.19% Zn,
0.46% Pb, 1% Cu, 14.7g/t Ag including 15.5m at 14.51% Zn,
0.9% Pb, 17g/t Ag & 43.85 metres at 9.95% Zn, 0.9% Pb,
8.2g/t Ag including 7.45 metres at 20.62% Zn, 0.3% Pb,
11.8g/t Ag. The mineralisation in this hole was hosted
within argillite with the presence of massive barite and carbonate
replacement, locally developing into massive sulphide. Although
infill drilling, these intersects were broader than the previous
resource model predicted and are expected to result in increased
tonnages.
Regional Exploration
Regional exploration has focused on the corridor
between the Western Orefield and the Gergarub deposit which is
located 10km to the North West of Rosh Pinah. The Western Orefield
is open along strike to the NW and eight exploration holes have
been completed from surface targeting this extension, seven of
which intersected the mineralized horizon. MGD159, intersected 6.5m
at 5.6% Zn+Pb & 6.1m at 5.9% Zn along the main argillite host
horizon. This intersection is located 200m away from the last fully
defined resources.
The same argillite hosted mineralized horizon
was intersected 400m further North of MGD159, however the grade is
weakening. Nevertheless, MGD164 intersected a 125m thick rhyolite
dome, with strong sericite-chlorite alteration with low grade
stringer style Sphalerite mineralisation throughout the dome. This
rhyolite is located to the East of the main Western Orefield
corridor. The identification of a new highly altered rhyolite dome
cross cut by sphalerite feeder veins in an area of limited
drilling, represents another strong exploration target for
2020.

regional exploration covering the prospective trend between Rosh
Pinah and Gergarub is available at
https://www.globenewswire.com/NewsRoom/AttachmentNg/10366927-0397-4dcc-9d6f-e6631f978a36
Along with drilling, several Fluxgate
electro-magnetic (EM) surveys were conducted in 2019 and are
currently ongoing covering the prospective Rosh Pinah - Gergarub
corridor. There has been no historic drilling between the Rosh
Pinah mine and Gergarub deposit, which share geological features,
and this ground is considered highly prospective. During 2019, 50%
of this corridor was covered with ground EM surveys. These surveys
have identified 4 new conductors in favorable geological settings
along strike from anomalous surface geochemistry. These discrete
conductive targets will be drill tested in 2020 and the ground EM
surveys will continue towards Gergarub.

Qualified Person and Quality
Control/Quality Assurance
Yan Bourassa, P.Geo, Trevali’s Vice-President
Exploration and Mineral Resources, is a qualified persons as
defined by NI 43-101. Mr. Bourassa supervised the preparation of
the scientific and technical information that forms the basis for
this news release and has approved the contents of this news
release. Mr. Bourassa is responsible for all aspects of the work,
including the quality control/quality assurance programs.
Regional exploration surface drillholes are
drilled using HQ-sized core (63.5-millimetre diameter core) for
overburden and weathered zones and NQ-sized core (47.6-millimetre
diameter core) in bedrocks. Surface exploration and any inferred
classification underground exploration drilling is performed by
contractors. The indicated and measured classification underground
exploration drilling is carried out by Rosh Pinah owner drill rigs.
Underground exploration drill holes are drilled at NQ-sized core
with core recovery above 95%.
Logging, sampling and analysis procedures comply
with current QA/QC procedures and NI 43-101 requirements. Logging
and sampling methodologies and procedures are documented, routinely
updated, and maintained by the exploration department.
Drill core is logged on site by a geologist for
lithological, structural, and geotechnical (core recovery, rock
quality designation (RQD), and rock mass rating) information. A
geo-data geologist supervises the database, which has set
validation specifications for populated data. Drill core is cut and
sampled onsite at Rosh Pinah. Half-core samples are prepared using
a specialized core saw utilizing fresh water. One half of the core
is stored with the rest of the core and the other half is sent to
the laboratory for analysis. Tertiary/production drill core is
wholly sampled.
Samples are packaged at the core shed and
registered into the Laboratory Information Management System (LIMS)
by assistants in the Mineral Resource Management Department, then
dispatched daily to the Rosh Pinah Mine Laboratory (“RPML”) located
on the mine site. On arrival, samples are checked, sorted, bar
coded, and activated in the LIMS.
Although the internal RPML is not
internationally certified, QA/QC procedures have been performed
systematically at Rosh Pinah Mine since 2009 and 5% of samples are
sent to an independent accredited facility. Standard procedures
developed and followed include the submission of blanks, duplicate
samples, and certified reference material, typically at every 18th
sample interval, to measure precision, accuracy, and bias in the
sampling and analytical process. Duplicates are taken every 14
samples with the duplicate retrieved by the assaying laboratory
personnel after the sample has been crushed, basically representing
a separate split. Duplicates are taken to quantify precision and
any bias introduced after the parent sample was duplicated (i.e.,
during milling, digestion and analysis). Sample duplication is also
conducted to ensure and demonstrate analytical repeatability. Check
assays of pulverized pulps are performed by a second lab and
generally represent 5 to 10% of the entire sample database.
Comparisons and reconciliation between original and check assays
are done routinely during drilling, and systematically before any
resource estimation exercise.
Sample custody is ensured on-site by continuous
inventorying and monitoring of drill core. Once samples are
prepared, using the methodologies described above, they are
inventoried, individually bagged, tagged, and sealed in larger bags
for transport to the assay lab. Audits of the assaying labs are
performed occasionally.

Forward-looking statements relate to future events or future
performance and reflect management’s expectations or beliefs
regarding future events including, but not limited to, statements
with respect to the Company’s growth strategies, the continued
success of mineral exploration, the content, cost, timing and
results of future exploration programs and life of mine
expectancies, Trevali’s ability to fund future exploration
activities, estimation of mineral reserves and mineral resources,
the realization of mineral reserve estimates, the timing and amount
of estimated future production, costs of production and capital
expenditures, success of mining operations, environmental risks,
unanticipated reclamation expenses and title disputes or claims. In
certain cases, forward-looking statements can be identified by the
use of words such as “plans”, “expects”, “outlook”, “guidance”,
“budget”, “scheduled”, “estimates”, “forecasts”, “intends”,
“anticipates” or “believes”, or variations of such words and
phrases or statements that certain actions, events or results
“may”, “could”, “would”, “might”, “will be taken”, “occur” or “be
achieved” or the negative of these terms or comparable terminology.
By their very nature, forward-looking statements involve known and
unknown risks, uncertainties and other factors which may cause the
actual results, performance or achievements of the Company to be
materially different from any future results, performance or

actions, events or results to differ materially from those
described in forward-looking statements, there may be other factors
that cause actions, events or results not to be as anticipated,
estimated or intended. Trevali provides no assurance that
forward-looking statements will prove to be accurate, as actual
results and future events may differ from those anticipated in such
statements. Accordingly, readers should not place undue reliance on
forward-looking statements.
