Summary:

The Troilus deposit is better known as an example of an Archean porphyry-type deposit as interpreted in the pioneering work of Fraser (1993). It is frequently cited as such, for example, Robert and Poulsen, 1997; Poulsen, 2000; Sinclair, 2007; Mercier-Langevin et al., 2012; Katz, 2016. Other interpretations for its genesis include superimposed structurally controlled “orogenic” gold, proposed by Carles (2000) and Goodman et al., (2005).

The Troilus deposit is located in the northeastern region of the Frotêt-Troilus domain, and is hosted by volcanic and hypabyssal intrusive rocks of the Troilus Group in a region of intense deformation, known as the Parker domain (Gosselin, 1996). It is located within the overturned northern limb of the Troilus isoclinal syncline, which was transposed by a series of northeast- southwest striking thrust fault zones, parallel to the main regional foliation and to the volcanic bedding.

Four main lithological units are recognized in the Troilus deposit region, broadly divided in: (i) mafic to felsic volcanic sequence; (ii) diorite and brecciated diorite; (iii) cross-cutting felsic dikes, and (iv) mafic to ultramafic intrusive. A series of distinct younger, post-deformation granitic intrusions crosscut all other lithotypes.

Troilus is primarily an Au-Cu deposit, but contains minor amounts of Ag, Zn and Pb, as well as traces of Bi, Te, and Mo. Gold-copper mineralization at the Troilus deposit comprises two distinct s ........

Summary:

Open Pit Mining
The PEA is based on the reactivation and expansion of the 87 and J Zone pits and the addition of a new area, the SW Zone. These pits provide the open pit feed material necessary to maintain the process plant feed rate at 35,000 t/d while operational.

The 87 pit is a single phase which provides 36.6 Mt of mill feed grading 0.72 gpt gold, 0.088% copper and 1.4 gpt silver for a gold equivalent grade of 0.85 gpt. Waste from this pit totals 149.4 Mt for a strip ratio of 4.1 (waste:mill feed). The 87 pit forms the top of the underground development.

The J zone pit has three phases. The phases total 94.8 Mt of mill feed grading 0.51 gpt gold, 0.06% copper, and 0.89 gpt silver for a gold equivalent grade of 0.60 gpt. Waste from the phases totaled 348.7 Mt for a strip ratio of 3.7:1 (waste:mill feed).

The new SW Zone pit is mined in two phases. They will produce 18.8 Mt of mill feed grading 0.64 gpt gold, 0.065% copper and 0.76 gpt silver for a gold equivalent grade of 0.74 gpt. The waste amounts to 93 Mt giving a strip ratio of 5.0:1 (waste:mill feed).

The phases are scheduled to provide 35,000 t/d of feed to the mill over a 14 year open pit mining life after one year of pre-production stripping. As the underground mine production comes online in Year 8 the open pit production drops to a level sufficient to keep the process plant at full capacity. The pits are sequenced to minimize initial stripping and provide high ........
