Deposit Type

  • Pegmatite


Summary:

The project is located in the region of The Archean Preissac-Lavorne which is a syn- to post-tectonic intrusion that was emplaced in the southern Volcanic Zone of the Abitibi Greenstone Belt of the Superior Province of Québec.

The spodumene pegmatites on the property are very poorly exposed.

The rocks are split between granodiorite of the Lacorne batholith, volcanics and some biotite shists, as well as the pegmatites dykes that mainly intrude the granodiorite and the volcanics.

Volcanic rocks on the property are represented by dark green mafic metavolcanics and medium grey silicified intermediate volcanics. The mafic rocks are medium grey to dark grey-green colour and cryptocrystalline to very fine grained.

Both mafic and intermediate volcanic rocks are affected by moderate to strong pervasive silicification, minor chloritisation and patchy to pervasive lithium alteration. There is alteration of the green hornblende in proximity to the spodumene pegmatite. There are also amphibolites that are fine grained, weakly foliated and dark green.

The granodiorite is medium grey to greenish grey, massive coarse grained to porphyritic, and exhibits a salt-pepper appearance. The main mineral constituents of granodiorites are light grey to greenish white plagioclase (40-45 vol%), dark green to black amphibole, most likely hornblende (15-20 vol%), mica(20 vol%), represented by biotite and muscovite, grey quartz (10-15%vol) and ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

Mining will be undertaken by conventional bulk mining methods utilising hydraulic excavators, dump trucks and drill and blast coupled to a ROM stockpile. Ore will be trucked directly from the blasted faces to the ROM stockpile and fed to the primary crusher using Front-End Loader (FEL). Allowance has been made for blending from the ROM and external stockpiles. The planned mining operation is based on 12 hour shifts with two crews working one week (7 days) double shifts and 2 weeks (14 days) single shifts.

Planned mining activities are as follows:

- Clearing of vegetation, stripping of topsoil and overburden, and removal to storage location on-site;
- Haul road and ramp construction;
- Drilling and blasting of ore and associated waste, including pre-splits on final walls;
- Loading of ore and waste from the pits;
- Haulage of ore to the ROM pad and waste to dump areas.

The pit will be mined using 2m and 3m flitches for ore and waste respectively. This height gives reasonable production efficiency while keeping dilution to a minimum. In waste, the flitch height could be increased to improve efficiency within the limits of the equipment size.

The proposed pit has been designed based on the geotechnical requirements and recommendations prepared by Golder Associates. The design outlines a pit of ~1,350m in length, an average of 750m width and down to a final pit depth of 270m.
