At the Galore Creek copper-gold-silver project located in Tahltan Territory in northwest B.C., we and our partner, Newmont Corporation (Newmont), decided to extend the prefeasibility study work into 2024 to complete additional value engineering for the project, with target completion in the fourth quarter of 2024. The Tahltan Central Government (TCG) signed a consent-based agreement with the Province of B.C. in November 2023 for joint assessment of the Galore Creek project, which is an important positive development. Social and environmental baseline studies, in collaboration with the TCG, will continue in 2024 to support preparation of an updated Initial Project Description, which is a key step in re-permitting this world-class copper-gold resource.

At Schaft Creek, also located in Tahltan Territory in northwest B.C., we are investing additional resources to progress environmental and social baseline field studies, and focused design and engineering data collection fieldwork. This includes resource modelling, geometallurgical and geotechnical studies, mining and mineral processing studies, siting studies, and capital and operating cost estimates, in support of advancing Schaft Creek towards a prefeasibility study in the fourth quarter of 2024.
