We strengthened our presence in the North American underground mining market with Barminco’s landmark contract at the Goldrush Project in Nevada in 2025. This achievement marked a significant step in expanding our global portfolio and showcased our capability to deliver complex underground development in one of the world’s most competitive mining regions.
Complementing this success is a major project in Canada – Red Chris in British Columbia (gold, copper).
