Mine Life | 1 years (as of Jan 1, 2018) |
The Reed mine produced its last ore in August, 2018 and processing of Reed ore was completed in early September, 2018. Closure activities at Reed mine were completed in October, 2018, with all equipment removed from site. Reclamation work is planned to continue in 2019. |

On April 27, 2016, Royal Nickel Corporation acquired 100% of VMS Ventures, which currently owns 27% of the Reed Mine. VMS is a private company whose main asset is an interest in the Reed Mine, a low-cost copper producer located near Flin Flon, Manitoba. Hudbay Minerals Inc. (“Hudbay”) owns the remaining 73% of the Reed Mine and has served as manager and operator.

Summary:
The property hosts a volcanogenic massive sulphide deposit that precipitated at or near the seafloor in association with contemporaneous volcanism, forming a stratabound accumulation of sulphide minerals. Volcanogenic massive sulphide deposits typically form during periods of rifting along volcanic arcs, fore arcs, and in extensional back arc basins. Rifting causes extension and thinning of the crust, providing the high heat source required to generate and sustain a high-temperature hydrothermal system (Franklin et al., 2005).
The location of volcanogenic massive sulphide deposits is often controlled by synvolcanic faults and fissures, which permit a focused discharge of hydrothermal fluids. A typical deposit will include the massive mineralization located proximal to the active hydrothermal vent, footwall stockwork mineralization, and distal products, which are typically thin but extensive. Footwall, and less commonly, hanging wall semiconformable alteration zones are produced by high temperature water-rock interactions (Franklin et al., 2005).
Mineralization begins at approximately 25m below surface and extends to approximately 580m below surface. Mineralization is generally fine to medium-grained disseminated to solid sulphides consisting of pyrrhotite, pyrite, chalcopyrite, sphalerite, and magnetite. The principle gangue minerals are chlorite, and quartz.
Summary:
Underground longhole stoping was chosen as the mining method for Reed because of the steep dip of the mineralization and good quality of the ground.
