PAN AMERICAN SILVER REPORTS MINERAL RESERVES OF 280 MILLION OUNCES AND CONTINUED SUCCESS AT THE LA COLORADA SKARN DISCOVERY
Pan American Silver Corp. has released its mineral reserves and resources as at Dec. 31, 2018. Pan American's mineral reserves are estimated to contain approximately 280 million ounces of silver and 1.7 million ounces of gold.
All financial figures are expressed in U.S. dollars unless otherwise indicated.
The following year-over-year silver reserves changes section provides the changes in Pan American's estimated silver reserves year over year.
Year-over-year silver reserves changes
Proven and probable silver mineral reserves as of Dec. 31, 2017 (1): 288.4 million ounces
Less: contained ounces mined during 2018: (29.7 million ounces)
Plus: contained ounces discovered by exploration during 2018: 21.1 million ounces
Proven and probable silver mineral reserves as of Dec. 31, 2018 (2) (3): 279.8 million ounces
(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.

attached to this news release for more detailed information.
"Two thousand eighteen 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 rest was expensed under exploration and project development costs. Drilling for mine and near-site exploration totalled 106,000 metres, with La Colorada and Morococha accounting for over 65 per cent of the metres drilled. An additional 10,000 metres were 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 Oct. 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, drill hole U-87-18, which was drilled 200 metres south of drill hole U-39-18 (reported in Pan American's news release dated Oct. 23, 2018, with 223 metres of polymetallic mineralization), is located in previously untested areas of the mine concession. Visit the company website to view cross-sections, plan and images of the mineralized core.
Recent drill highlights include:
-
U-60-18: 44.5 metres at 40 grams per tonne silver, 0.10 per cent copper, 1.97 per cent lead and 4.71 per cent zinc;
- 48.8 m at 29 g/t Ag, 0.17 per cent Cu, 1.39 per cent Pb and 4.33 per cent Zn;
- 67.9 m at 18 g/t Ag, 0.07 per cent Cu, 0.57 per cent Pb and 4.67 per cent Zn;
-
U-68-18: 308.1 m at 46 g/t Ag, 0.20 per cent Cu, 1.93 per cent Pb and 4.56 per cent Zn;
- Including 65.7 m at 80 g/t Ag, 0.40 per cent Cu, 2.34 per cent Pb and 5.73 per cent Zn;
- Including
75.0 m at 70 g/t Ag, 0.23 per cent Cu, 3.01 per cent Pb and 6.02 per cent Zn;
- Including 90.4 m at 38 g/t Ag, 0.19 per cent Cu, 2.25 per cent Pb and 6.15 per cent Zn;
- U-87-18: 64.7 m at 33 g/t Ag, 0.16 per cent Cu, 1.99 per cent Pb and 2.93 per cent Zn;
-
Including 11.5 m at 71 g/t Ag, 0.31 per cent Cu, 4.47 per cent Pb and 4.57 per cent Zn.
A summary of the drill results from the recently completed 6,800 metres of drilling is provided in 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 metres of drilling will be directed toward the skarn discovery at La Colorada 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 30 of each year, rather than at the period ending Dec. 31 of each year, 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.
A summary of the silver and gold mineral reserve and resource information at Dec. 31, 2018, is provided in the attached reserves and resources tables.

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 SEDAR for further information on the company's material mineral properties, other than the Joaquin property, including information concerning associated quality assurance/quality control and data verification matters, the key assumptions 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 Dec. 21, 2017.
Grades are shown as contained metal before mill recoveries are applied. Samples from the first 16 drill holes 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 the company's 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 drill holes (hole U-60-18 onward) was prepared and analyzed by Activation Laboratories Ltd. 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 Oct. 23, 2018, the failed batches were resubmitted to the laboratory for reanalysis, and the primary laboratory was switched to Actlabs. The results of the QAQC samples submitted to Actlabs demonstrate acceptable accuracy and precision, and 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 the Pan American Silver website.
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, PEng, senior vice-president, technical services and process optimization, who are each qualified persons for the purposes of National Instrument 43-101.
