Preliminary metallurgical test
results are positive
VANCOUVER, Oct. 30, 2019 /CNW/ - Pan American Silver
Corp. (NASDAQ: PAAS) (TSX: PAAS) today announced results
from 14,300 metres of drilling completed during the third quarter
of 2019 on the La Colorada skarn
discovery in Mexico. Preliminary
metallurgical testing of samples indicates high recoveries across
all metals can be expected.
"The most recent drill results feature some of the highest grade
intercepts we have seen to date, with widths up to 379 metres.
Stand-out drill holes include U-66-19 with 253 metres grading at 67
grams per tonne of silver, 3.84% lead and 6.56% zinc," said
Christopher Emerson, Pan American's
Vice President Business Development and Geology. "We have now
completed over 52,400 metres of drilling on the skarn target,
allowing us to substantially expand the mineralized footprint and
to identify a high-grade core zone."
Drill highlights include:
- D-57-01-19: 250.9 m at 40
g/t Ag, 0.08% Cu, 2.57% Pb and 3.43% Zn
including 78.9 m at 60 g/t Ag,
0.09% Cu, 3.90% Pb and 4.84% Zn
- D-57-02-19: 72.3 m at 37
g/t Ag, 0.16% Cu, 3.80% Pb and 6.25% Zn
and 56.6 m at 39 g/t Ag, 0.10%

and 148.6 m at 81 g/t Ag,
0.23% Cu, 4.43% Pb and 7.66% Zn
- U-72-19: 132.5 m at 56 g/t
Ag, 0.19% Cu, 3.81% Pb and 6.32% Zn
including 57.9 m at 80 g/t Ag,
0.24% Cu, 5.46% Pb and 9.42% Zn
and 139.2 m at 54 g/t Ag,
0.15% Cu, 1.80% Pb and 5.87% Zn
- U-73-19: 278.0 m at 26 g/t
Ag, 0.08% Cu, 1.56% Pb and 3.98% Zn
- U-79-19: 379.0 m at 54 g/t
Ag, 0.50% Cu, 1.96% Pb and 3.73% Zn
including 57.9 m at 47 g/t Ag,
0.37% Cu, 2.83% Pb and 6.35% Zn
and 66.7 m at 154 g/t Ag,
2.07% Cu, 0.97% Pb and 1.58% Zn
The drilling continues to define a polymetallic mineralized
skarn system and cross-cutting veins starting 300 metres below and
adjacent to the current lowest production level of the La Colorada mine. Drill holes D- 57-01-19 and
D-57-02-19 were drilled 200 metres to the southwest of a
mineralized hydrothermal breccia zone, indicating the potential to
extend mineralization further to the southwest. Drill results for
the hydrothermal breccia zone were previously announced in Pan
American's news release dated August 1,
2019.
Pan American expects to complete over 50,000 metres of drilling
in 2019, and provide an initial resource estimate of the skarn
discovery by the end of 2019. An intensive exploration program and
further metallurgical testing will continue in 2020. Given that the
skarn deposit is more massive than the existing vein structures,
pending technical studies, future development would conceptually
require new mining, processing and other facilities.
In addition to the drilling program, Pan American has advanced
initial metallurgical testing at the independent ALS Metallurgy
laboratory in Kamloops, Canada. To
date, flotation tests and mineral liberalization analysis on three
composites samples have been performed. Positive flotation recovery
results for silver, lead, zinc and copper were obtained, with the
preliminary bulk rougher flotation recovery ranges and averages
provided in the table below. Preliminary open cleaner tests show
that good concentrate qualities can be obtained, ranging from 50%
to 70% Pb in the lead cleaner concentrate, 55% to 63% Zn in the
zinc cleaner concentrate and 20% to 31% Cu in the copper cleaner
concentrate. Minor element analysis results in concentrates are
pending. Pan American plans to prepare additional composite
samples, as we get more information on the resource, and to conduct
additional flotation tests.

forward-looking statements or information. Forward-looking
statements or information in this news release relate to, among
other things: the anticipated exploration and other development
programs at the Company's La
Colorada properties, together with the nature,
implementation and timing thereof, the exploration and
metallurgical results of such programs, and our expectation and
timing of establishing resource information based on such
programs.
These forward-looking statements and information reflect the
Company's current views with respect to future events and are
necessarily based upon a number of assumptions that, while
considered reasonable by the Company, are inherently subject to
significant operational, business, economic and regulatory
uncertainties and contingencies. These assumptions include: our
mineral reserve and mineral resource estimates and the assumptions
upon which they are based; ore grades and recoveries; prices for
silver, gold, and base metals remaining as estimated; currency
exchange rates remaining as estimated; capital, decommissioning and
reclamation estimates; prices for energy inputs, labour, materials,
supplies and services (including transportation); all necessary
permits, licenses and regulatory approvals for the La Colorada mine are received in a timely
manner; our ability to secure and maintain the surface rights
necessary for our operations; and our ability to comply with
environmental, health and safety laws. The foregoing list of
assumptions is not exhaustive.
The Company cautions the reader that forward-looking statements
and information involve known and unknown risks, uncertainties and
other factors that may cause actual results and developments to
differ materially from those expressed or implied by such
forward-looking statements or information contained in this news
release and the Company has made assumptions and estimates based on
or related to many of these factors. Such factors include, without
limitation: fluctuations in silver, gold and base metal prices;
fluctuations in prices for energy inputs, labour, materials,
supplies and services (including transportation); fluctuations in
currency markets (such as the Canadian dollar, Peruvian sol,
Mexican peso, Argentine peso and Bolivian boliviano versus the U.S.
dollar); operational risks and hazards inherent with the business
of mining (including environmental accidents and hazards,
industrial accidents, equipment breakdown, unusual or unexpected
geological or structural formations, cave-ins, flooding and severe
weather); employee relations; relationships with, and claims by,
local communities and indigenous populations; our ability to obtain
all necessary permits, licenses and regulatory approvals in a
timely manner; changes in laws, regulations and government
practices in the jurisdictions where we operate, including
environmental, export and import laws and regulations; legal
restrictions relating to mining; risks relating to expropriation;
increased competition in the mining industry for equipment and
qualified personnel; and those factors identified under the caption
"Risks Related to Pan American's Business" in the Company's most
recent form 40-F and Annual Information Form filed with the United
States Securities and Exchange Commission and Canadian provincial
securities regulatory authorities, respectively. Although the
Company has attempted to identify important factors that could
cause actual results to differ materially, there may be other
factors that cause results not to be as anticipated, estimated,
described or intended. Investors are cautioned against undue
reliance on forward-looking statements or information.
Forward-looking statements and information are designed to help
readers understand management's current views of our near and
longer term prospects and may not be appropriate for other
purposes. The Company does not intend, nor does it assume any
obligation to update or revise forward-looking statements or
information, whether as a result of new information, changes in
assumptions, future events or otherwise, except to the extent
required by applicable law.
