Coeur completed approximately 90,000 feet (28,000 meters) of drilling in 2023 over 92 holes, 62 of which were in the Southern Silver Zone. Since acquisition of the project in late 2017, the Company has drilled roughly 1.1 million feet (333,000 meters) over 1,244 holes.

Highlights from surface and underground expansion drilling completed last year are reported below and continue to support Silvertip’s status as one of the world’s highest-grade, undeveloped carbonate replacement deposits.

Key Highlights^1,2,3

• Extremely high-grade intercept highlights continued growth of the Southern Silver Zone – Results have been received for almost half of total 2023 drilling at the Southern Silver Zone, including the highest-grade intercept ever received in the zone. Drillhole 65Z23-485-012-022, which assayed 16.1 feet at 36.8 ounces per ton (“oz/t”) (4.9 meters at 1,261.4 grams per tonne (“g/t”)) silver, 22.0 % lead and 22.4% zinc or 3,053 g/t on a silver equivalence basis
• Strike of Southern Silver Zone increased by 150 meters and down dip extent by 160 meters – Southern Silver Zone is the largest chimney structure discovered on the property to date and accounts for approximately 10% of Silvertip’s total measured and indicated resource and 55% of Silvertip’s total inferred resource as of year-end 2022. Additional notable drilled intercepts from Southern Silver Zone include:
  • Hole 65Z22-485-010-030: 10.6 feet at 14.4 oz/t (3.2 meters at 492.0 g/t) silver, 5.9% lead and 8.1% zinc
  • Hole 65Z22-485-010-036: 29.8 feet at 3.5 oz/t (9.1 meters at 121.0 g/t) silver, 1.5% lead and 4.6% zinc
  • Hole 65Z23-485-012-004: 20.7 feet at 2.5 oz/t (6.3 meters at 87.0 g/t) silver, 1.1% lead and 10.8% zinc
  • Hole 65Z23-485-012-008: 9.5 feet at 16.6 oz/t (2.9 meters at 568.0 g/t) silver, 12.0% lead and 4.5% zinc
  • Hole 65Z23-485-012-021: 25.4 feet at 2.6 oz/t (7.7 meters at 88.0 g/t) silver, 0.8% lead and 7.2% zinc and 10.9 feet at 8.2 oz/t (3.3 meters at 282.0 g/t) silver, 3.5% lead and 16.7% zinc
