Mining

• Development of the Abore pit continued during Q2 2025 with mined ore totaling 0.8 Mt, an increase of 18% from Q1 2025, at an average grade of 0.9 g/t gold. The strip ratio at Abore was 6.2:1, a decrease of 17% from Q1 2025.

• Continued mining operations at the Esaase deposit with mined ore totaling 0.5 Mt at an average grade of 0.7 g/t gold and a strip ratio of 5.5:1.

• Mining cost per tonne at Abore and Esaase averaged $3.59 per tonne (“/t”) in Q2 2025 compared to $2.98/t in Q2 2024 at Abore only. The increase in mining unit rates was due to higher load and haul costs associated with mining deeper benches, as well as higher drill and blast costs resulting from mining a higher proportion of fresh granite ore at Abore.

• Continued with waste stripping of Cut 3 at the Nkran deposit with 1.7 Mt of waste rock mined during Q2 2025, an increase of 113% from Q1 2025. Mined volumes at Nkran are expected to gradually increase as the mining contractor continues to mobilize most of its mining fleet over the remainder of this year.

• At Nkran, mining cost per tonne was $4.00 for Q2 2025, which included an allocation of general overhead costs. Nkran waste stripping costs were capitalized as development capital expenditures during the quarter.
