- Current drilling program at the Contacto Sur Medio zone
reflects high grade polymetallic sulphide mineralization which
continues and remains open at depth
- The Contacto Sur Medio zone is within close proximity to
current mine production areas which could reduce the time and capex
to integrate the material from this zone into the mine
plan
- Six holes have been completed to date from the 1070 level in
the Contacto Sur Medio zone
- Drill hole 17-18-03 intercepted over five meters of
continued high grade polymetallic sulphide mineralization that
includes a head grade of 36% Zinc

TORONTO, June 7, 2018 /PRNewswire/ - Sierra Metals
Inc. (TSX: SMT) (BVL: SMT) (NYSE AMERICAN: SMTS) ("Sierra
Metals" or "the Company") today announced positive drilling results
on high-grade structures at the Contacto Sur Medio zone located
close to current operations and within the Central Mine at
Yauricocha.
To date, six holes have been executed from the 1070 level of the
Yauricocha Mine in the Contacto Sur Medio zone. These holes have
intercepted polymetallic sulphide mineralization, containing
high-grade silver, zinc, and lead. These results demonstrate the
potential for high-grade mineralization within the reported area
and more importantly indicate the continued existence of extensive
mineralization at depth. Today's results come as part of an ongoing
brownfield drilling program testing priority targets at the
Yauricocha Mine, located 150 kilometers east-southeast of Lima in
the Yauricocha Mining District (Cordillera Occidental),
Peru.
"Management is very excited about today's results as they
represent the existence of high-grade polymetallic mineralization
at The Contacto Sur Medio zone" commented Igor Gonzales, President, and CEO of Sierra
Metals. "We see zinc grades that are more than 35% along
with high-grade Silver more than 700 g/t. These results along with
other exploration results recently released continue to demonstrate
the excellent return on the Company's capital investments into
exploration with the potential for further growth of mineral
resources while adding high-value tonnage."
Alonso Lujan, Vice President,
Exploration of Sierra Metals commented: "The results reported
from Contacto Sur Medio demonstrate high-grade, sulphide
mineralized sectors containing primarily silver, lead and zinc as
shown in table 1 below. The potential exists for further extensions
to be defined within the Contacto Sur Medio zone, which remains
open at depth. Today's results demonstrate the considerable
high-grade nature of these structures." He added,
"based on the value of the mineralization defined to date,
exploration will continue to define the further potential that
still exists."
All reported intercepts are core length as further drilling is
required to determine true thicknesses.
A map of the Yauricocha Mine 1070 level (Central Mine) is shown
in Figure 1. Figure 2 shows the Contacto Sur Medio
zone. Figure 3 and 4 show the cross sections of all the drill
holes.

includes, but is not limited to, statements with respect to the
Company's operations, including the anticipated developments in the
Company's operations in future periods, the Company's planned
exploration activities, the adequacy of the Company's financial
resources, and other events or conditions that may occur in the
future. Statements concerning mineral reserve and resource
estimates may also be considered to constitute forward-looking
statements to the extent that they involve estimates of the
mineralization that will be encountered if and when the properties
are developed or further developed. These statements relate to
analyses and other information that are based on forecasts of
future results, estimates of amounts not yet determinable and
assumptions of management. Any statements that express or involve
discussions with respect to predictions, expectations, beliefs,
plans, projections, objectives, assumptions or future events or
performance (often, but not always, using words or phrases such as
"expects", "anticipates", "plans", "projects", "estimates",

"potential" or variations thereof, or stating that certain actions,
events or results "may", "could", "would", "might" or "will" be
taken, occur or be achieved, or the negative of any of these terms
and similar expressions) are not statements of historical fact and
may be forward-looking information.
Forward-looking information is subject to a variety of risks and
uncertainties, which could cause actual events or results to differ
from those reflected in the forward-looking information, including,
without limitation, risks inherent in the mining industry including
environmental hazards, industrial accidents, unusual or unexpected
geological formations, floods, labour disruptions, explosions,
cave-ins, weather conditions and criminal activity; commodity price
fluctuations; higher operating and/or capital costs; lack of
available infrastructure; the possibility that future exploration,
development or mining results will not be consistent with the
Company's expectations; risks associated with the estimation of
mineral resources and the geology, grade and continuity of mineral
deposits and the inability to replace reserves; fluctuations in the
price of commodities used in the Company's operations; risks
related to foreign operations; changes in laws or policies, foreign
taxation, delays or the inability to obtain necessary governmental
permits; risks relating to outstanding borrowings; issues regarding
title to the Company's properties; risks related to environmental
regulation; litigation risks; risks related to uninsured hazards;
the impact of competition; volatility in the price of the Company's
securities; global financial risks; inability to attract or retain
qualified employees; potential conflicts of interest; risks related
to a controlling group of shareholders; dependence on third
parties; differences in U.S. and Canadian reporting of mineral
reserves and resources; potential dilutive transactions; foreign
currency risks; risks related to business cycles; liquidity risks;
reliance on internal control systems; credit risks, including risks
related to the Company's compliance with covenants with respect to
its BCP Facility; uncertainty of production and cost estimates for
the Yauricocha Mine, the Bolivar Mine and the Cusi Mine; and other
risks identified in the Company's filings with Canadian securities
regulators and the U.S. Securities and Exchange Commission ("SEC"),
which filings are available at www.sedar.com and www.sec.gov,
respectively.
This list is not exhaustive of the factors that may affect any
of the Company's forward-looking information. Forward-looking
information includes statements about the future and are inherently
uncertain, and the Company's actual achievements or other future
events or conditions may differ materially from those reflected in
the forward-looking information due to a variety of risks,
uncertainties and other factors. The Company's statements
containing forward-looking information are based on the beliefs,
expectations, and opinions of management on the date the statements
are made, and the Company does not assume any obligation to update
forward-looking information if circumstances or management's
beliefs, expectations or opinions should change, other than as
required by applicable law. For the reasons set forth above, one
should not place undue reliance on forward-looking information.
Note Regarding Reserve and Resource Estimates
All reserve and resource estimates reported by the Company are
calculated in accordance with the Canadian National Instrument
43-101 - Standards of Disclosure for Mineral Projects and the
Canadian Institute of Mining and Metallurgy Classification system.
These standards differ significantly from the requirements of the
SEC. The differences between these standards are discussed in our
SEC filings. Mineral resources which are not mineral reserves do
not have demonstrated economic viability.
