Vancouver, B.C. – December 5, 2023 - Pan American Silver Corp. (NYSE: PAAS) (TSX: PAAS) ("Pan American" or the "Company") released new exploration drill results for its Jacobina, El Peñon, La Colorada, Huarón and Timmins properties and for its La Colorada Skarn project. These drill results demonstrate continued potential for organic growth of mineral reserves and mineral resources in and around the Company's operations.

“The recent exploration drilling at Jacobina continues to reflect the geological potential to expand the resource base close to existing mine infrastructure, specifically in the Maricota and João Belo Sul sectors, both of which have the potential to add higher margin ounces. The large mineral reserve and mineral resource base, together with a study underway to optimize the economic life of mine, underpin the growth potential and strong economics of the Jacobina property,” said Christopher Emerson, Pan American’s Vice President of Exploration and Geology. “We also continue to discover new targets and build new resources at our other mines, such as at La Colorada, El Peñon, Huarón and Timmins. In addition, multiple mineralised intercepts of over 100 metre widths have further expanded and added confidence to the large mineralisation footprint at the La Colorada Skarn project, demonstrating the world-class nature of the deposit.”

Pan American's drill program in 2023 is focused on near-mine exploration and resource conversion throughout its portfolio of operating mines. A total of 373,780 metres has been drilled during the ten months ended October 31, 2023, out of a 450,000 metre drill program planned for 2023. The mineral reserves and mineral resources update as at June 30, 2023, which was released on August 24, 2023, reflects only a portion of the 2023 drill program. The Company plans to incorporate the results of the full 2023 drill program, including results for the Company's other assets not referenced in this news release, in a mineral reserve and mineral resource update as at June 30, 2024.

See Table 1 of this news release for drill result highlights

•Continued success in defining mineralisation outside the João Belo Sul mineral resource. Step-out drilling approximately 200 metres to the north returned 4.85 metres at 14.69 g/t Au, including 1.15 metres at 59.25 g/t Au and 7.70 metres at 4.83 g/t Au, including 3.36 metres at 7.45 g/t Au (drill hole JBS00041). These results confirm continuity and higher-grades along a 700 metre strike between João Belo Sul and João Belo mine.

•Exploration drill results at Maricota, close to current infrastructure, show potential for future mineral resource addition over an approximate 2,000 metre strike length by 1,000 metre depth profile, with intercepts at higher-grade than average resource grade, such as 4.69 metres at 23.45 g/t Au, including 1.26 metres at 40.90 g/t Au and 1.52 metres at 35.17 g/t Au (drill hole MRCEX00004).

See Table 2 of this news release for drill result highlights

•Nine drillholes within the dacite intrusive unit north of the Pampa Campamento structure returned higher grades outside of the current mineral resource and mineral reserve footprint. Highlights include (estimated true widths): 1.20 metres at 114.50 g/t Au and 72 g/t Ag (drill hole UIP0145), 1.80 metres at 28.90 g/t Au and 205 g/t Ag (drill hole UIP0146) and 1.74 metres at 19.14 g/t Au and 230 g/t Ag (drill hole UIP0149). Mineralisation is defined over an approximate 150 metre vertical extent and remains open both along strike and down plunge to the north.

•At El Valle, drilling confirmed the extension of mineralisation in the El Valle vein and parallel El Valle -30 splay, located northwest of Pampa Campamento. Mineralisation remains open to the south for further expansion within the favourable rhyolite stratigraphy. Drill highlights include 2.30 metres at 46.50 g/t Au and 805 g/t Ag and 0.80 metres at 40.70 g/t Au and 1,775 g/t Ag (drill hole SEV0004).

See Table 3 of this news release for drill result highlights

•Exploration drilling on the east extension of the NC2 vein has shown high-grade silver intercepts. Drill highlights from 15,873 metres drilled this year include: 1.05 metres at 2,804 g/t Ag, 1.59% Pb and 1.33% Zn (drill hole U-75-23) and 1.33 metres at 4,067 g/t Ag, 0.76% Pb and 1.82% Zn (drill hole S-84-23). The high-grade zone is now defined by 50 metre-grid drill spacing, from the 498 to 588 level (approximately 100 metre vertical) over a 200 metre strike length. This area remains open to the northeast and to depth with ongoing drilling focused on definition of further extensions.

See Table 4 of this news release for drill result highlights

•More than 280,000 metres have been drilled on the project, with 97,000 metres completed since the last mineral resource update issued on September 14, 2022. Recent drilling has focused on the 902 skarn zone with 24 infill drill holes, which follow up on mineralisation reported in prior news releases dated May 2, 2023, November 1, 2022, and July 21, 2022. Results confirm wide zones of high-grade silver mineralisation, as demonstrated by 332.40 metres at 144 g/t Ag, 4.11% Pb and 4.78% Zn, including 89.85 metres at 461 g/t Ag, 10.63% Pb and 11.05% Zn (drill hole D-93-09-23).

•Exploration drilling successfully extended the 902 skarn zone 100 metres to the northwest. Highlights from extensional drilling in this area include 161.10 metres at 96 g/t Ag, 1.86% Pb, and 3.00% Zn (drill hole U-43-23).

See Table 5 of this news release for drill result highlights

•In 2023, drilling and mine sill development focused on the Horizonte zone, an emerging shallow multiple vein system located southeast of the core mine area that is becoming an important production area. Of the 14,510 metres drilled at Huarón, 5,545 metres (38%) were focused on the Horizonte zone. Intercepts from 10 drill holes within three structures in the Horizonte zone all returned positive results that will contribute to future resource models.

See Table 6 of this news release for drill result highlights

•Drilling in 2022 (39 holes totaling 7,849 metres) and 2023 (26 holes totaling 5,979 metres) tested remnant mineralisation in both unmined veins and wall rock adjacent to historic mined stopes, confirming current resources in Hallnor and historic resources in Broulan Reef zone, 1.5 km to the west. The Hallnor zone is referenced in Pan American's mineral reserves and mineral resources update as at June 30, 2023, under the name of Whitney, a joint venture (82.5% Pan American / 17.5% Newmont) in which Pan American is the operator. The Hallnor zone is estimated to contain 586,000 ounces of measured and indicated gold mineral resource and 141,400 ounces of inferred gold mineral resource.

•Significant assays in the Hallnor zone include: 1.20 metres at 145.73 g/t Au (drill hole TW22-719), 5.80 metres at 26.64 g/t Au and 3.10 metres at 9.97 g/t Au (drill hole TW22-712), 16.60 metres at 5.39 g/t Au (drill hole TW22-705A), 8.00 metres at 6.76 g/t Au (drill hole TW22-709) and 4.60 metres at 10.43 g/t Au (drill hole TW22-694) (all reported over core lengths).

•Significant assays from the drilling at Broulan Reef include: 10.00 metres at 38.11 g/t Au (drill hole TW23-747), 8.00 metres at 6.39 g/t Au (drill hole TW23-740), 9.00 metres at 6.38 g/t Au (drill hole TW23-745), 9.0 metres at 3.45 g/t Au (drill hole TW23-743) and 3.00 metres at 4.71 g/t Au (drill hole TW23-730) (all reported over core lengths).

The Jacobina mine is an underground paleo placer gold mine located in the state of Bahia in northeastern Brazil. The mine has a strong track record of mineral reserve and mineral resource replacement and growth. The mine complex extends over eight kilometres with resources and exploration targets over a 14 kilometre trend where gold mineralisation is hosted in conglomerate reefs that remain open to depth and along strike in multiple areas. The Jacobina property consists of a mining claim, mining concessions and exploration permits over 155 kilometres in a north-south direction and five to 25 kilometres in an east-west direction.

Brownfield exploration drilling totaled 44,006 metres with drilling completed largely at the João Belo Sul, Maricota, João Belo Norte, Moro do Vento, and Serra do Corrego zones. Recent Jacobina exploration results demonstrate upside potential for mineral reserve and mineral resource growth.

Drill results at João Belo Sul, together with the mineral reserves and mineral resources update as at June 30, 2023 that reported an additional 215,000 ounces of indicated gold mineral resource and 81,000 ounces of new inferred gold mineral resource, as well as the addition of 58,000 ounces of probable mineral reserve, affirm the potential for continued mineral reserve and mineral resource growth. Recent infill and exploration drilling at João Belo Sul confirm mineralisation grade and continuity along strike and to depth, particularly along higher-grade ore shoots.

Maricota represents an opportunity to add higher-grade mineral resources close to existing mine infrastructure at the northern end of the Jacobina mine. Exploration drilling, initiated in 2022, continues to extend mineralisation along a strike length greater than two kilometres and to depth, where historic drill results include 9.72 g/t of gold over 1.80 metres (drill hole MVTEX22) and 12.28 g/t of gold over 2.39 meters (CANEX006). The Company is working to complete an initial mineral resource estimate for Maricota in 2024.

The following table provides infill and exploration drill result highlights for the João Belo Sul and Maricota Zones of the Jacobina mine. Full infill and exploration drill results not included in this table, together with cross sections and plans, are available at https://panamericansilver.com/operations/exploration/.

El Peñon is a large, high-grade multi-vein system located in northern Chile. Exploration drilling totaling 48,407 metres, mainly in the core mine area, includes 13,805 metres of infill drilling to convert inferred mineral resources to indicated mineral resources, and 33,748 metres of exploration drilling to define new near-mine inferred mineral resources. Exploration drilling was directed at expanding the mineralisation envelope along multiple core mine structures, most notably Pampa Campamento and El Valle veins in the southwest mine sector. Both areas remain targets for drilling in 2024 and are expected to contribute new mineral resources for the mineral reserve and mineral resource update as at June 30, 2024.

Pampa Campamento is currently one of the most important veins contributing to production at El Peñon. Infill and exploration drilling have extended mineralisation towards the north within an intrusive unit. Step out drilling north of current resources below the 1,400 metre level has extended mineralisation approximately 150 metres vertically. Mineralisation remains open in this area, both down plunge and along strike, as well as in splays such as Pampa Campamento -35, Pampita and Pampa Campamento Oeste.

At El Valle, infill and exploration drilling confirmed mineralisation in the El Valle vein and parallel El Valle -30 splay, where drill holes returned higher grades over horizontal widths ranging up to 2.50 metres. The zones remain open to the south within the favourable rhyolite stratigraphy.

Pan American is currently designing a drill program to address the reserve reconciliation issue identified in 2023.

The following table provides infill and exploration drill result highlights for the Pampa Campamento and El Valle vein systems of the El Peñon mine. Full infill and exploration drill results not included in this table, together with longitudinal sections and plans, are available at https://panamericansilver.com/operations/exploration/.

The La Colorada mine is a silver-rich polymetallic mine located in the state of Zacatecas, Mexico. A total of 108 holes for 29,569 metres were drilled on the vein targets (NC2, Veta 3, Recompensa, Amolillo and minor splays) through the mine from both surface and underground with the focus on infill drilling. Exploration success was reported on the high-grade east extension NC2 vein where 39 holes for 15,873 metres were drilled.

Most of the drill holes on NC2 extend the high-grade vein areas to the east, which are now drilled at roughly 50 metre spacing. The high-grade zone is defined from the 498 to 588 level (approximately 100 metre vertical) over a 200-metre strike length. This area remains open to the northeast and to depth with ongoing drilling focused on definition of further extensions.

The following table provides the drill result highlights for the La Colorada mine. Full drill results not included in this table, together with cross sections and plans, are available at https://panamericansilver.com/operations/exploration/.

The La Colorada Skarn deposit was discovered in 2018, and is located at depth adjacent to the La Colorada polymetallic mine area in Zacatecas, Mexico. The skarn zone extends from 900 to 1,800 metres below the surface and comprises three distinct bodies (901 Main zone, 902 West zone, 903 East zone).

Exploration drilling has continued to define and expand the current resource. Since the last mineral resource update provided on September 14, 2022, a total of 97,000 metres has been drilled with continued exploration success in expanding mineralisation northwest of ore body 902 while adding infill definition to the high-grade portion of the deposit (see news release dated July 21, 2022). An initial economic study of the La Colorada Skarn project will be released in the fourth quarter of 2023.

A total of 44 new infill and exploration drill holes covering 43,337 metres were completed. This news release includes 34 holes for 33,751 metres drilled since the last drill results update issued on May 2, 2023.

Recent drilling has focused on definition of the 902 skarn zone with 24 infill drill holes designed to follow up on mineralisation reported in news releases dated May 2, 2023, November 1, 2022 and July 21, 2022. Results confirm wide zones of high-silver grade mineralisation highlighted by drill holes D-93-09-23 and D-05-01-23 (see table below for assays). This drilling confirms the high-grade nature of the silver mineralisation, which is now defined by more than 35 drill holes on a 40-metre spaced grid over a strike length of 250 metres.

Exploration drilling also successfully extended 902 ore body mineralisation 100 metres to the northwest with drill hole U-43-23 (see table below for assays).

The Huarón mine is a polymetallic (Zn-Pb-Ag-Cu) deposit located in the Cerro de Pasco Department of central Peru. Drilling in 2023 focused on brownfield extensions with 71 holes totaling 14,510 metres. Drilling aimed to define new inferred mineral resources on principal structures in the lower portion of the mine (Tapada vein) as well as the near surface Horizonte zone, an emerging shallow multiple vein system southwest of the core mine area. A large portion of the new resources is defined by sill development (development on the vein structure) in the Cuerpo Andres, Maria, Lucero and other splays southeast of the main mine.

Of the 11 drill holes totaling 1,730 metres completed on the Tapada vein, four holes are extension holes that define high-grade areas, now drilled at roughly 45 to 50 metre spacing. The drilling in 2023 confirms extension of mineralisation above level 0 (4,000 masl) and for at least 50 metres below the deepest mine development drift. The Tapada zone remains open to depth, and to the east and west where current drilling continues to test further vein extensions.

In the Horizonte zone, 21 holes covering 5,545 metres were drilled. Intercepts from 10 drill holes within three structures have all returned positive results that will contribute to future resource models.

On the Cuerpo Andres vein, 11 holes covering 3,756 metres were completed with four holes drilled as extensions in the high-grade areas. Drilling at roughly 45 to 50 metre spacing in the Cuerpo Andres zone confirms extension of mineralisation 25 metres below the lowest mine development drift.

Sill development within the main structures in the Horizontes zone has generated positive results that are expected to convert to new resources. Channel sampling using over 350 individual samples within 184 channels over a cumulative strike length of 415 metres of sill development on the Maria splay, Lucero, Cuerpo Andes and Ochentayuno structures averaged 2.92 metres at 246 g/t Ag, 4.9% Pb, 5.7% Zn.

The following table provides infill and exploration drill result highlights from the medium, lower and Horizonte sectors of the Huarón mine. Full drill and channel sampling results not included in this table, together with cross sections and plans, are available at https://panamericansilver.com/operations/exploration/.

The Timmins West and Bell Creek mines, located outside of Timmins, Ontario are Archean orogenic gold deposits associated with greenstone-hosted quartz veins. The Whitney project is located 4.5 kilometres south of the Bell Creek processing plant and adjacent to the Palmour open pit operated by Newmont Corporation. The project is a joint venture (82.5% Pan American / 17.5% Newmont Corporation) in which Pan American is the operator, with historic production, most notably from the Hallnor and Broulan Reef mines, that produced just over 2.3 million ounces of gold. Infill, exploration drilling and technical studies are planned for 2024. The Hallnor zone is referenced in our mineral resource and mineral reserve update as at June 30, 2023 under the name of Whitney.

Drilling in 2022, comprised of 39 holes totaling 7,849 metres, and drilling in 2023, comprised of 26 holes totaling 5,979 metres, tested mineralisation left in both unmined veins and the wall rock of mined stopes in the upper Hallnor zone and Broulan Reef zone 1.5 kilometres west of Hallnor.

Most of the recent drilling at Hallnor targeted areas in the shallow part of the deposit that had previously been the subject of a historic resource estimation calculated based on selective historic sample data. Results from recent drilling confirm historic resource shapes, and in some cases, intersected mineralisation outside of the current resource models. Drilling at Hallnor resumed in the fourth quarter of 2023, after the completion of the Broulan Reef exploration program.

Significant assays from the drilling at Broulan Reef confirm the mineral resources in the upper part of the zone and drill hole TW23-730 intersected mineralisation approximately 50 metres below the historic resource.

The following table provides infill and exploration drill result highlights from the Hallnor and Broulan reef deposits of the Whitney Project. Full infill and exploration drill results not included in this table, together with cross sections and plans, are available at https://panamericansilver.com/operations/exploration/.
