Summary:

The Kiena Complex project lies within the Abitibi Subprovince of the Archean Superior craton,
eastern Canada. The Kiena Complex project straddles the limit between the southern part of the Abitibi Subprovince and the northern part of the Pontiac Subprovince. In this region, the Cadillac Tectonic Zone (CTZ) marks the separation between the two. Fromsouth to north, the Project is underlain by the lithologies of the Pontiac Group (PO), the Piché Group (PG), the Héva Formation (HF), the Val-d’Or Formation (VDF), the Jacola Formation (JF) and the La Motte-Vassan Formation (LVF).

The region has several large-scale strike faults and/or shear zones, trending W to WNW and dipping steeply to the north. They are, from south to north: the Cadillac Tectonic Zone (CTZ), the Parfouru Fault (PF), the Marbenite Fault (MF), the Norbenite Fault (NF), the Callahan Fault (CF), the K Shear Zone (KSZ), and the Rivière Héva Fault (RHF). The Quebec Wesdome Project is cut by all of them. These major structures contain dykes or stocks of monzonitic or tonalitic composition with highly variable ages (pre, syn- or post-tectonic) that are spatially associated with several gold mines (Norlartic, Marban, Kiena, Sullivan, Goldex, Siscoe, Joubi, Sigma and Lamaque). The observed diversity in the styles and ages of gold mineralization related to these large-scale strike faults and/orshearzones demonstratesthatseveral distinct episodes of mineralization occur.

Mining Methods

  • Overhand stoping
  • Underhand stoping
  • Longhole stoping
  • Longitudinal retreat
  • Paste backfill


Summary:

Most of the production mining will utilize the overhand long hole stope method, historically used at the Kiena Mine Complex. In cases where production mining is expected under previously mined and backfilled stopes, the underhand long hole stope method will be utilized.

Long hole production stopes will be mined on a longitudinal retreat basis. Stope empirical designs and mine sequencing were established for each of the three mining zones accounting for key factors influencing stability including rock mass quality, the orientation of the principal structures, in situ stress and the geometry of the stope. Cemented rockfill, rockfill and paste backfill were considered for supporting the rock mass after extraction. Mining recovery will be maximized and production stope cycle time optimized in the Kiena Deep A Zone by making paste backfill the predominant backfill type.

Both existing and new infrastructure are required to support the LOM plan. The key existing infrastructure includes the hoisting shaft extending to a depth of 930 m with an average hoisting capacity of 2,000 tpd, ore and waste pass systems, the underground crusher, underground ventilation raise and ramp system, service repair, fueling, refuge, process water, mine dewatering, compressed air and electrical facilities.

Haulage trucks and load haul dumps (LHD) are currently owned and operated by a contracted mining company for ore and waste rock haulage. Most other mobile equipment is a ........
