Deposit Type

  • VMS


Summary:

The Rainy River deposit is an auriferous VMS system (Pelletier 2016) with a primary synvolcanic source and possibly a secondary syn-tectonic mineralization event (MercierLangevin et al. 2015).

Wartman (2011) and Pelletier (2016) have proposed that gold mineralization was introduced alongside base metals prior to the main deformation event at Rainy River, through fluid flow associated with a syn-volcanic hydrothermal system.

The peak hydrothermal activity and associated metal deposition is thought to have occurred during a volcanic activity hiatus during which fine-grained, pyrite-rich sediments were deposited on top of the dacitic volcanic rocks that host the ODM zone, and before the deposition of tholeiitic basalts in the uppermost part of the host succession.

An early, pre-D2 origin for the alteration and sulphide zones is further supported by the strong control of the combined S2 and L2 fabrics on the shape of the mineralized zones and lithological contacts.

At Rainy River, gold and silver are the dominant metals and the base metal (Cu-Pb-Zn) sulphides, although good indicators of the presence of gold, represent less than 10%, by volume, of the host rock. This is in contrast with other VMS systems that generally contain large amounts of base metals. However, there are exceptions, i.e., gold-rich VMS deposits that often contain modest amounts of base metals relative to gold (MercierLangevin et al. 2015 and references therein).

Summary:

The open pit mine plan considers mining open pit ore at a strip ratio of 2.32:1 (waste:ore) over a mine life from 2022 to 2025, with full depletion of the open pit in 2026. The operating cut-off grade for direct processing decreased in the February 2022 life of mine plan to a range ; however, the lower grade open pit ore will continue to be stockpiled for processing during the underground mine life, which continues beyond the completion of open pit mining.

The life of mine plan for the Rainy River Mine includes a component of underground mining. Development of the underground Intrepid Zone began in 2018 but was suspended late that year in order to review and optimize the underground mine plan. Work on the Intrepid Zone restarted in September 2020. Underground mining from the Intrepid Zone commenced in 2022 and underground mining is expected to ramp-up over the underground mine life with peak production from 2026 to 2028. The underground main zone will be accessed via an in-pit portal with development expected to commence in late 2023. There remains potential for underground mine life extension should the gold price environment support the inclusion of additional mining areas during the underground mine life and/or exploration efforts increase the resource inventory.

Surface mining uses a conventional truck/shovel open-pit mining method, with 10 metre benches. The pit was designed considering the geology of the bedrock, which is considered to have a good ........
