Commencement of the underground portal development within Rainy River Mine’s open pit marks the beginning of a new phase to enhance the extraction efficiency and resource yield of the mine as the operation transitions to underground. This second access point to the underground workings brings New Gold one step closer to underground Main Zone production set to begin in 2025.
“We’re all excited to see this work progressing here at Rainy River,” said Alex Alousis, Underground Mine Manager. “Our progress toward achieving these milestones as a team has been very rewarding, and we are looking forward to beginning Rainy River’s next chapter underground.”
Removal of loose rock and installation of ground support was completed at the area surrounding the portal to reinforce the ground and ensure stability of the portal face. These are crucial steps in preparation for the mobilization of underground development equipment within the pit including drilling jumbos, rock bolters, loaders, and additional infrastructure for power, water, and compressed air.
“There are many people and teams working at the same time on different aspects of this project to make it happen,” said Alousis. “With work this complex, coordination, effective planning and an unwavering focus on safety are crucial.”
Simultaneously, Rainy River’s underground team is completing the development from the underground towards the pit portal that will connect before the end of the year. The focus remains on developing the portal ramp alongside other crucial infrastructure required along the way. Reaming of the fresh air raise finished in August and will provide the main ventilation for the mine beginning in Q2 2025 upon completion of the surface fan construction.
These coordinated efforts between the surface and underground teams demonstrate detailed and complex planning and will eventually result in a fully integrated project that will pave the way for safe and streamlined access and transportation within the underground mine.
