Pan American Silver Reports Mineral Reserves of 280 Million Ounces and Continued Success

at the La Colorada Skarn Discovery

All financial figures are expressed in US$ unless otherwise indicated.

The reserve and resource information provided in this news release is only for Pan American's operations and do

not reflect the plan of arrangement (the "Arrangement") whereby Pan American will acquire all of the issued and

outstanding common shares of Tahoe Resources Inc. ("Tahoe"), announced on November 14, 2018. Pan American

currently expects the Arrangement to be completed on or about February 22, 2019.

Vancouver, B.C. - Feb. 20, 2019 - Pan American Silver Corp. (NASDAQ: PAAS) (TSX: PAAS) (“Pan

American”, or the “Company”) today reported its mineral reserves and resources as at December 31,

2018. Pan American’s mineral reserves are estimated to contain approximately 280 million ounces of

silver and 1.7 million ounces of gold.

The following table provides the changes in Pan American's estimated silver reserves year-over-year:

Millions of ounces

Proven and probable silver mineral reserves as of Dec. 31, 2017(1) 288.4

Less: contained ounces mined during 2018 (29.7)

Plus: contained ounces discovered by exploration during 2018 21.1

Proven and probable silver mineral reserves as of Dec. 31, 2018(2)(3) 279.8

(1) Prices used to estimate mineral reserves for 2017 were $18.50 per ounce of silver, except at Manantial Espejo where $16.50 per ounce of

silver was used for planned 2018 production, reverting to $18.50 per ounce of silver thereafter.

(2) Prices used to estimate mineral reserves for 2018 were $18.50 per ounce of silver, except at Manantial Espejo where $16.50 per ounce of

silver was used.

(3) Please refer to the complete mineral reserves and mineral resources table at the end of this news release for more detailed information.

“2018 was a very successful year for near-site mine exploration with the replacement of over 21 million

ounces of silver and the major skarn discovery at La Colorada, which is not yet reflected in our proven

and probable reserves or resources," said Christopher Emerson, Pan American's Vice President Business

Development and Geology. “Drill hole U-68-18 with 308 metres of polymetallic mineralization is another

impressive result of this major discovery”.

2018 Exploration Results

Pan American spent $18.8 million on exploration drilling in 2018, of which $11.3 million was included in

capital for mine and near site drilling, and the remainder was expensed under exploration and project

development costs. Drilling for mine and near site exploration totaled 106,000 metres, with La Colorada

and Morococha accounting for over 65% of the metres drilled. An additional 10,000 metres was drilled

for regional exploration.

La Colorada (Mexico) - added 11.1 million ounces of new silver reserves with approximately 14,000

metres drilled to further define the main vein continuity laterally and at depth. The Company also drilled

approximately 6,800 metres to further define the manto and skarn mineralization discovery announced

on October 23, 2018.

Exploration drilling of the skarn mineralization at depth, approximately 500 to 800 metres below the drill

stations, indicates wide intercepts with high-grade, polymetallic mineralization. In particular, drillhole

U-87-18, which was drilled 200 metres south of drillhole U-39-18 (reported in Pan American’s news

release dated October 23, 2018, with 223 metres of polymetallic mineralization), is located in previously

untested areas of the mine concession. Visit panamericansilver.com to view cross sections, plan and

images of the mineralized core.

Recent drill highlights include:

• U-60-18: 44.5 m at 40 g/t Ag, 0.10% Cu, 1.97% Pb, 4.71% Zn;

• and 48.8 m at 29 g/t Ag, 0.17% Cu, 1.39% Pb, 4.33% Zn;

• and 67.9 m at 18 g/t Ag, 0.07% Cu, 0.57% Pb, 4.67% Zn

• U-68-18: 308.1 m at 46 g/t Ag, 0.20% Cu, 1.93% Pb, 4.56% Zn,

• including 65.7 m at 80 g/t Ag, 0.40% Cu, 2.34% Pb, 5.73% Zn;

• including 75.0 m at 70 g/t Ag, 0.23% Cu, 3.01% Pb, 6.02% Zn;

• including 90.4 m at 38 g/t Ag, 0.19% Cu, 2.25% Pb, 6.15% Zn

• U-87-18: 64.7 m at 33 g/t Ag, 0.16% Cu, 1.99% Pb, 2.93% Zn,

• including 11.5 m at 71 g/t Ag, 0.31% Cu, 4.47% Pb, 4.57% Zn

A summary of the drill results from the recently completed 6,800 metres of drilling is provided at the end

of this news release.

Morococha (Peru) - added 7.7 million ounces of new silver reserves, in addition to an increase of 76,000

tonnes of zinc and 21,000 tonnes of lead, which is associated with the increase in polymetallic

mineralization at depth. The continued exploration drilling success at Morococha underlines the

potential of this district, especially in the eastern portion of the mine.

Huaron (Peru) - added 4.9 million ounces of silver, primarily through the conversion of resources on the

principal structures to reserves due to the 100 level deepening project.

Manantial Espejo/Joaquin/COSE (Argentina) - 3.5 million ounces of silver reserves were depleted from

the low grade stockpile and underground mine at Manantial Espejo. The Company is focused on the

development of the high-grade Joaquin and COSE deposits to supplement ore from Manantial Espejo.

Exploration drilling at Manantial Espejo continued to define mineralized shoots along the Maria vein.

2019 Exploration Program

In 2019, Pan American plans to invest approximately $20 million in exploration, and complete about

122,000 metres of diamond drilling; about 42,000 meters of drilling will be directed towards the skarn

discovery at La Colorada in order to release an initial mineral resource estimation later in 2019.

Future Mineral Reserve and Resource Updates

Pan American intends to provide future mineral reserve and resource updates as at the period ending

June 30th of each year, rather than at the period ending December 31st of each year, in order to optimally

align mineral reserves updates, mine plans and budgets. This change will take effect on June 30, 2019,

and the updated mineral reserve and resource estimates are expected to include the Tahoe assets that

will be added to the Company's portfolio following completion of the Arrangement.

General Notes with Respect to Technical Information

Mineral reserves and resources are as defined by the Canadian Institute of Mining, Metallurgy and

Petroleum.

Pan American reports mineral resources and mineral reserves separately. Reported mineral resources do

not include amounts identified as mineral reserves. Mineral resources that are not mineral reserves have

no demonstrated economic viability.

Pan American does not expect these mineral reserve and resource estimates to be materially affected by

metallurgical, environmental, permitting, legal, taxation, socio-economic, political, and marketing or

other relevant issues.

See the Company’s Annual Information Form dated March 22, 2018, available at www.sedar.com for

further information on the Company’s material mineral properties, other than the Joaquin property,

including information concerning associated QA/QC and data verification matters, the key assumptions,

parameters and methods used by the Company to estimate mineral reserves and mineral resources, and

for a detailed description of known legal, political, environmental, and other risks that could materially

affect the Company’s business and the potential development of the Company’s mineral reserves and

resources. For information on the Joaquin property, please refer to the Company's news release dated

December 21, 2017.

Grades are shown as contained metal before mill recoveries are applied. Samples from the first 16

drillholes in the new manto/skarn discovery (holes U-01-18 to U-57-18) were analyzed at the La

Colorada mine laboratory, which is operated by our employees, using fire assay with gravimetric finish

for gold and silver, and by acid digestion with atomic absorption finish for lead, zinc, and copper. The

majority of the samples from the subsequent drillholes (hole U-60-18 onwards) were prepared and

analyzed by Activation Laboratories Ltd (“Actlabs”) of Zacatecas, Mexico, using fire assay with gravimetric

finish for gold and silver, and by acid digestion with atomic absorption finish for lead, zinc, and copper.

Pan American Silver implements a quality assurance and quality control ("QAQC") program including the

submission of certified standards, blanks, and duplicate samples to the laboratory. As a result of some

blank and standard failures associated with analyses conducted at the La Colorada mine laboratory, as

reported in Pan American's news release dated October 23, 2018, the failed batches were re-submitted

to the laboratory for re-analysis and the primary laboratory was switched to Actlabs. The results of the

QAQC samples submitted to Actlabs demonstrates acceptable accuracy and precision, and that no

significant contamination is occurring at the laboratory. The Qualified Person is of the opinion that the

sample preparation, analytical, and security procedures followed for the samples will be sufficient and

reliable for the purpose of any future mineral resource and mineral reserve estimates.

Complete mineral reserve and resource information for all metals, including tonnage and grades, is

available at www.panamericansilver.com.

Technical information contained in this news release with respect to Pan American has been reviewed

and approved by Christopher Emerson, FAusIMM., Vice President Business Development and Geology,

and Martin Wafforn, P.Eng., Senior Vice President Technical Services and Process Optimization, who are

each Qualified Persons for the purposes of National Instrument 43-101.
