2025 GOODMAN GOLD CHALLENGE

#GGC2025 CASE COMPANIES

G Mining Ventures

The GMIN story begins with Louis Gignac Sr., Chairman of the Board, 2016 Canadian Mining Hall of Fame inductee. Mr. Gignac Sr. is best known for building Quebec-based Cambior Inc. into an international gold producer. Throughout Cambior’s history, the company was renowned for the construction and development of its own projects rather than relying on the more conventional approach of outsourcing to EPCM contractors. After 20 years, Cambior was acquired in 2006 for US$1.3 billion, sparking the creation of the family owned engineering and consulting firm, G Mining Services (GMS).

Meridian Mining

Meridian Mining is focused on the development and exploration of the advanced stage Cabaçal VMS gold‐copper project, and on regional scale exploration of the Cabaçal VMS belt in Mato Grosso, Brazil. Cabaçal is a gold‐copper‐silver rich VMS deposit with the potential to be a standalone mine within the 50km VMS belt.
