The Project Area hosts two principal styles of mineralization that have been the target of past and current exploration. The first and older style is porphyry Cu-Au mineralization related to intrusion and alteration by Late Triassic alkalic to sub-alkalic diorite to monzonite dykes and stocks exemplified by the Central Zone and Donnelly Deposit. The second comprises later, structurallyhosted and high-grade gold zones associated with shearing, fracture zones and quartz-carbonate vein/fault controlled pyrite, arsenopyrite, sphalerite, galena and chalcopyrite hosted by altered volcanic units and monzonite dykes.

Porphyry-Style Mineralization - Central Zone
Porphyry-style Cu-Au mineralization occurs within a north-south trending, moderately west dipping and fault-bounded structural panel of Triassic Stuhini volcaniclastic lithologies intruded by syn- to late-mineral monzonite dykes. Porphyry- style mineralization has been defined over a strike length of 1,000 m, with widths of 70 m to 200 m, it has been tested to 400 m downdip and it remains open along strike and downdip.

Mineralization occurs as quartz-pyrite-chalcopyrite with or without magnetite veinlets, stockworks, fracture fills and fine grained disseminations of pyrite and chalcopyrite. Metal grades appear to be directly related to the abundance of quartz-sulphide-magnetite vein development.

Porphyry-Style Mineralization - Donnelly Deposit
Of the many porphyry Cu-Au prospects l ........

Conventional truck and shovel open pit mining was selected because, overall, it represents the least risk, most sustainable option from both economic and environmental perspectives.

Spectrum Pit
It is earlier established that for purposes of the PEA, access to the Spectrum Pit area is limited to a mid-pit point. A 6.0 m wide access road with a maximum gradient of 10% is planned, along which passing cut-outs will be excavated. Topographic constraints and the resultant truck cycling times preclude the use of the access road for muck hauling. ROM material from the Spectrum Pit will instead be tipped directly onto a grizzley with an associated rock breaker to reduce over-size blocks (for the reasons earlier outlined, few such blocks are anticipated). Material tipped on the grizzley will report directly to a raise bored, gravity fed muck pass system that reports to a loading box via a dog-leg to reduce the speed of muck reporting to the box front. The loading facility is located underground, at the back of a suitably dimensioned drift; B-Train trucks will be loaded at the box front, from where they will haul the muck to a laydown area at the MIA.

Donnelly Pit
A similar muck handling system to the preliminary and provisional system described above for Spectrum Pit has also been adopted for Donnelly Pit, except a 15 m wide pit access road is planned, along with a primary crusher located at the base of the raise bore muck pass.
