Deposit Type

  • Vein / narrow vein
  • Mesothermal
  • Sedimentary - Volcanogenic


Summary:

The Seabee mine, Santoy mine, and Porky deposits host mesothermal, quartz-vein hosted lode gold deposits developed in major brittle-ductile to ductile shear systems. The gold mineralisation throughout the SGO exhibits complex geometrical patterns attributed to a combination of structural and/or lithological controls.

Mesothermal gold deposits typically emplaced as a system of en echelon veins, forming tabular veins in competent host rock lithologies, or as stockwork veinlets and stringers in less competent host rock lithologies. Lower grade bulk-tonnage style mineralisation with gold associated with disseminated sulfides may develop in areas peripheral to quartz veins. Mesothermal gold deposits can also be related to broad areas of fracturing, where gold and sulfides are associated with quartz veinlet networks. The quartz veins are typically in sharp contact with the wall-rock and can display a variety of textures including massive, ribboned or banded, and stockworks with anastomosing gashes and dilations, which may subsequently be altered or destroyed during deformation. Gold-quartz veins are found within zones of intense and pervasive carbonate alteration along faults proximal to trans crustal breaks, and often occur at a high angle to the primary collisional fault zone. They are commonly associated with late syn-collisional, structurally controlled intermediate to felsic magmatism, with economic deposits generally hosted by large competent units, such as intrusi ........


Mining Methods

  • Longhole stoping
  • Alimak
  • Avoca
  • Cemented backfill


Summary:

Actual data and current operating practice are referenced heavily as the mine plan is based on the successful continuation of current practice. Mining at Seabee is now complete therefore all mining references relate to the Santoy mine.

The mine plan was initially completed by the SSR technical department on site at the Seabee Gold Operation (SGO) and included plans for the overall extraction of the Mineral Resource. OreWin has since reviewed the mine plan and made the appropriate modifications to include extraction of only the Mineral Reserve.

The LOM plan of the Mineral Reserve at SGO, commencing 1 January 2022, includes 2.68 Mt at an average grade of 6.7 g/t Au. The Mineral Reserve estimate includes dilution from hangingwall and footwall overbreak based on ongoing stope reconciliation. A total of 580 koz of gold will be delivered to the mill.

Access underground at the Santoy mine is provided from surface at the Santoy portal via a main ramp, with sublevels spaced between 17–20 m vertically. Mining is carried out using sublevel open stoping mining methods with backfill.

Stopes are filled with a combination of rock fill (RF) and cemented rock Fill (CRF), mined in a bottom-up mining sequence. Sill pillars are mined on retreat once the stopes below and above have been mined (stopes above filled with CRF and allowed to cure).

Mining factors are derived from ongoing analysis of site performance data.
