Bringing James Bay to full production in 2018??, page-2

As it stands JB has a combined 20mt of spod so makes it almost twice as big as Mt Cattlin.

The James Bay lithium pegmatite Project in Quebec, Canada contains indicated resources of 11.75 million tonnes grading at 1.30% Li2O and inferred resources of 10.47mt grading at 1.20% Li2O. The James Bay deposit occurs at surface and resource modelling indicates that the resource is amenable to open pit extraction. There is excellent potential to increase the resources through additional delineation of the pegmatite dykes along strike and at depth and potential to increase grade through infill drilling.


The Project is located in northwest Quebec, two kilometres south of the Eastmain River and 100 kilometres east of James Bay. The topography is gently rolling to flat lying with much of it covered by muskeg. Outcrops are common, usually occurring as mounds or ridges above the surrounding plain.
The Project is readily accessible by paved road as the James Bay Highway bisects the property 384 kilometres from Mattagami where there is an airport and mining infrastructure. The property can be accessed by aircraft with an airstrip only 15 kilometres away. The Relais Routier gas station and truck stop is located one kilometre from the property with helicopter access, fuel, motel and restaurant services.
The James Bay Project lies in the northeast part of the Superior Province, within the Archean Lower Eastmain greenstone belt composed predominantly of amphibolite grade mafic to felsic metavolcanic and metasedimentary rock and minor **bro. The deposit area is underlain by the Auclair Formation consisting of mainly paragneiss intruded by spodumene-bearing pegmatite dykes. Volcanic rocks of the Komo Formation occur north of the pegmatite dykes. The greenstone rocks are surrounded by migmatite and gneiss.
The deposit comprises of several swarms of pegmatite dykes. Surface mapping identified 15 different pegmatite swarms, each consisting of up to seven dykes. The individual pegmatite bodies are mainly irregular dykes or lenses attaining up to 60 metres in width and over 100 metres in length.
The pegmatite outcrops form a discontinuous band or “corridor” approximately four kilometres long and 300 metres wide, cutting the host rock at a low angle and cross-cutting the regional foliation at a high angle.
Pegmatites formed by the crystallisation of post-magmatic fluids enriched in light elements such as lithium, boron and beryllium inside the crust. Geological investigations to date reveal that the pegmatite dykes at James Bay are almost always spodumene-bearing.
The mineral spodumene (chemical formular LiAlSi2O6), in its pure form contains 8.02% Li2O. Spodumene crystals at James Bay are relatively coarse, usually more than 5cm in length and sometimes exceeding one metre.
