Pan American Silver Corp. provided an annual exploration update and releases new exploration drill results for its Jacobina, El Peñon, La Colorada, Huaron, Minera Florida and Timmins mines, as well as its La Colorada Skarn project. EXPLORATION HIGHLIGHTS: All intercepts are reported as estimated true widths in metres ("m"), except for the La Colorada Skarn, which is a massive orebody and intercepts are reported as drilled.

Jacobina - extensional and infill drilling in the Maricota and the Morro do Vento zones demonstrate the potential for future resource expansion. Significant results at grades higher than the average resource grade include: 1.42m @ 116.41 g/t Au and 8.74m @ 5.86 g/t Au (Maricota - MRCEX00056); 12.75m @ 3.71 g/t Au, incl. 8.35m @ 5.26 g/t Au (Maricota - MRCEX00052); 5.75m @ 5.24 g/t Au, incl.

2.11m @ 11.68 g/t Au (Morro do Vento - MVTEX00223). El Peñon - drilling of the principal structures and areas to the south continues to return high-grade intercepts that are typical for this deposit. Significant results include: 1.05m @ 18.89 g/t Au, 746 g/t Ag (Pampa Campamento - UIP0177); 1.09m @ 9.90 g/t Au, 97 g/t Ag (Pampa Sur - SEP0055); 4.10m @ 3.62 g/t Au and 1,592 g/t Ag (Dominadora - UEH0024); and 1.46m @ 0.44 g/t Au and 2,547 g/t Ag (Chiquilla Chica - UIH0049).

La Colorada - 13 new veins have been discovered in the eastern portion of the property, expanding the high-grade zone of the mine. Significant results within the Mariana, NC2 splay and San Geronimo veins show continued high-grade results, notably: S-104-24 with 0.95m @ 9,618 g/t Ag, 4.85% Pb, 4.82% Zn (Mariana vein); S-154-24 with 2.32m @ 2,615 g/t Ag, 2.31% Pb, 5.16% Zn (NC2 vein); and S-168-24 with 3.28m @ 308 g/t Ag, 10.18% Pb, 13.09% Zn (Cristina vein). La Colorada Skarn project - infill drilling reinforced confidence in the large, indicated mineral resource update as at June 30, 2024.

Notable intercepts include: 273.10m at 54 g/t Ag, 0.85% Pb, and 5.18% Zn, incl. 62.55m at 84 g/t Ag, 1.97% Pb, and 7.57% Zn (U-155-24); and 60.25m at 85 g/t Ag, 7.05% Pb, and 10.41% Zn (U-19-24). Whitney Project (Timmins) - the increase in estimated gold mineral resources provided in the June 30, 2024 mineral reserve and mineral resource update highlights the potential of the Whitney project, while ongoing drilling of the Bonetal/Hallnor and Broulan reef has continued to yield high-grade results along the mineralized trend, including 360 g/t Au over 2.4 metres (TW24-793).

Huaron - significant results from drilling focused on the Horizonte zone include: DDH-U-111-24 with 2.10m @ 399 g/t Ag, 7.39% Pb and 14.58% Zn (Maria vein); DDH-U-113-24 with 1.50m @ 504 g/t Ag, 12.77% Pb and 19.97% Zn (Maria Vein); DDH-U-049-24 with 2.77m @ 768 g/t Ag, 1.85% Pb and 0.62% Zn (Cuerpo Andres); Minera Florida - exploration and infill drilling have extended mineralization at several key mine structures. Significant results include: 1.98m @ 16.11 g/t Au, 13 g/t Ag and 6.44% Zn and 1.97m @ 9.38 g/t Au, 23 g/t Ag, and 4.96% Zn (Maqui Norte vein - ALH4638); and 2.57m @ 10.32 g/t Au, 12 g/t Ag, and 0.08% Zn (Mila Sur vein - ALH4562). SUMMARY OF EXPLORATION RESULTS Jacobina mine, Brazil 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 and resources extend over eight kilometres with exploration targets extending over a 14 kilometre trend of conglomerate reefs hosting gold mineralization, many of which remain open to depth and along strike.
