Pan American Silver Corp. 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.

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. 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/tAu, 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). 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). 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.

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 holeU-43-23). 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 resultsthat will contribute to future resource models. 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 Corporation) 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/tAu 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/tAu (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).
