Detour Lake Mine

Highlights

• The Company continues to advance various optimization initiatives, with a target to increase mill throughput to 79,450 tpd (equivalent to 29 Mtpa) by 2030.
• In June 2024, on the basis of a new technical study reflecting the potential for a concurrent underground operation at Detour Lake, the Company approved a 2-km exploration ramp, which will provide access for underground conversion and expansion drilling and to collect a bulk sample from the shallow mineralized zone west of the pit. The underground project is accelerating access to higher grade ore and could potentially increase average annual production to approximately 1 million ounces over 14 years starting in 2030.
• In 2025, drilling continued to delineate a subset of the mineral resources that is amenable to underground mining within and adjacent to the open pit mineral resource. At year-end 2025, this high-grade mineralized corridor increased substantially relative to the June 2024 technical study to 5.5 million ounces of gold in indicated mineral resources (85.8 million tonnes grading 2.00 g/t gold) and 5.8 million ounces of gold in inferred mineral resources (89.8 million tonnes grading 2.02 g/t gold).
