Intrusion-associated disseminated sulphide mineralization is commonly found along the PDMFZ and, as its name implies, is spatially related to porphyritic intrusions. Two areas have a large number of these mineralized zones: the periphery of the Duparquet basin and the Fayolle deposit area. Two subtypes have been identified based on intrusion composition: calc-alkaline and alkaline (Legault et al., 2006). The Fayolle occurrence has been described in the past as a calc-alkaline quartz-feldspar porphyry (QFP) or feldspar-porphyry (FP) intrusion-related disseminated sulphide deposit (Legault et al., 2006). However, the newly geological understanding of the Fayolle deposit differs from this earlier description.

The Fayolle deposit is characterized by the komatiite flows of the Lanaudiere Formation (Goutier, 1997) intruded by a swarm of quartz-feldspar porphyry and/or feldspar porphyry dykes. A post-intrusive brecciation event seems to control gold deposition. The breccia zones mostly affect the ultramafic flows, but also locally contain felsic dyke fragments.

The northern part of the Fayolle Property is underlain primarily by the Lanaudière Formation, which corresponds to the summit of the Kinojevis Group. Basalt is the dominant rock type, and basalt layers are intercalated with felsic and ultramafic rocks. Also observed are ultramafic flows, magnesian basalt, and komatiite characterized by breccia, cumulates and spinifex texture. The east-trending Manneville ........

According to InnovExplo, the conventional open pit option is the better way to successfully mine the deposit and extract the most resources while minimizing the economic risk.

Mining will be undertaken by contractors using conventional truck and shovel equipment.

Ore Handling and Crushing
Underground ore is hoisted to surface and hauled by truck to the processing facility located 2.5km from the mine shaft. The ore is discharged at the crusher house. The ore is fed to a single stage jaw crusher (1.07 x 1.22m) by a front-end loader through a grizzly feeder. The ore is conveyed to the mill ore bins using a belt conveyor system. Each bin has a capacity of 2,800dmt.

Grinding and Gravity
Grinding of the Westwood ore is done using a 2,700HP semi-autogenous grinding (SAG) mill in closed circuit with primary hydrocyclones. The overflow of primary hydrocyclones feeds a 1,000-HP ball mill in closed circuit with its secondary hydrocyclones. A portion of the underflow (secondary hydrocyclones) feeds the gravity separation circuit composed of a sweco screen, Knelson concentrator (30’’) and a shaking table. The tail of the gravity circuit returns to the grinding circuit and the gravity gold concentrate goes to the refinery. The targeted grind size is 80% passing 53 microns (270 mesh).
