Deposit Type

  • Metamorphic
  • Mesothermal
  • Porphyry
  • Vein / narrow vein


Summary:

The gold mineralization at the West Cache Property is a mesothermal lode gold deposit in an Archean greenstone belt setting. Mesothermal gold deposits in the Abitibi Greenstone Belt are spatially associated with large-scale regional structures such as the PDFZ. These large-scale structures and associated Timiskaming-type sedimentary units are interpreted to be zones of transpressive terrain accretion. The general consensus is that greenstone-hosted mesothermal lode gold deposits formed from metamorphic fluids generated by prograde metamorphism and liberated during accretionary processes and thermal re-equilibration of subducted volcano-sedimentary terranes.

The West Cache Property porphyry-hosted gold deposits resemble those at the Hollinger and McIntyre Mines, located approximately 15 km to the east. The deposits are characterized by chalcopyrite-pyrite stringers and veins, and quartz-tourmaline veins, and hosted by altered and sheared QFP. MacDonald (2010) suggests that the gold mineralization and porphyry intrusions are not genetically related, but occur along common emplacement conduits.

Pyrite, the most important sulphide for visually estimating gold grade, is observed in many different styles. Fine-grained disseminated pyrite is typically associated with lower, but consistent gold grades, whereas coarser-grained euhedral to subhedral pyrite grains (“buckshot pyrite”) are a reliable indicator of higher gold grades. When the coarser-formed pyrite gr ........


Mining Methods

  • Longitudinal retreat
  • Cemented backfill


Summary:

The West Cache Deposit is comprised of 41 mineralized domains and extends over an area of approximately 2.2 km x 1.7 km. Mineralization is expected to be extracted from 20 of these domains, covering an area of 2.1 km x 1.2 km. The Deposit extends at depth over 1.0 km from surface, with extraction targets covering the entire vertical extent. Due to the large extents of the Mineral Resource, it has been divided into four mining areas (Mines A-D) with separate portals. Each mining area is further sub-divided into mining “Blocks” to increase available working faces and limit development requirements prior to commencement of production.

Extraction of mineralized material in all areas will use Longhole retreat stoping (“LH”) with Cemented Hydraulic Fill (“CHF”) at 4% binder by mass being used to eliminate in-situ pillars and maximize the extraction of the Mineral Resource. Artificial sill pillars comprised of higher-strength CHF (nominally 6% by mass) will be used to segregate the blocks where required. In addition to artificial sill pillars, a crown pillar extending 30 m from the overburden/host rock contact will be left until being extracted at the end of mine life.

Capital development will be sized to support 30 t haul trucks and 10 t load-haul-dump (“LHDs”), with operating development being slightly smaller, and sized to support 7 t LHDs for production operations. Material will be transported from the stopes to re-muck bays at the level access, prior ........
