Coeur Mining, Inc. provided updates on its exploration programs at the Kensington underground gold mine in Alaska, and the Silvertip polymetallic exploration project in British Columbia. Results shown here are the start of a delineation program on these intersections that will continue through 2023 and into 2024. Notable 2023 results from expansion and infill drilling include the following true width intercepts: Hole K23-0220-125-X01 returned 6.9 feet at 3.31 ounces per ton ("oz/t") gold (2.1 meters at 113.4 grams per tonne ("g/t") gold); Hole K23-0220 -059-X01 returned 11.4 feet at 0.51 oz/t gold (3.5 meters at 17.4 g/t gold); Hole K23-2-059-X06 returned 0.8 feet at 7.0 oz/t gold (0.2 meters at 239.8 g/t gold).

Hole K 23-0220-091-X07 returned 2.6 feet at 1.75 oz/t gold (0.,8 meters at 59.9 g/t gold); HoleK22-0220-091 -X05 returned 0.9 feet at 4.50 oz/t gold 0.3 meters at 154.3 g/t gold) and 0.9 feet at 1.87 oz/t gold (0.'3 meters at 64.1 g/t gold); Hole T23-0220-091, returned 3.1 feet at 0.74 oz/t gold (0".9 meters at 25.4 g/t gold). HoleK23-0220- 125-X05 returned 2.5 feet at 0.73 oz/t gold (0 the8 meters at 25 g/t gold); Hole H23-0220-059-X11 returned 11.2 feet at 0.21 oz/t gold (3.4 meters at 7.1 g/t gold). New zone (Zone 30C) discovered at Upper Kensington - Recent expansion drilling at Upper Kensington has led to the discovery of the new Zone 30C zone, with drilling extending mineralization by approximately 400 feet along strike.

The drill program at Upper Kensington continues to trace key mineralized structures to the south and down dip and has outlined a new parallel vein structure that already extends 950 feet along strike and 800 feet down dip. Testing this large vertical extent of stratigraphy is a key focus of the upcoming drill program.
