The Sirmac property is underlain by the Frotet-Evans volcano-sedimentary belt. In the Assinica Lake region, the belt comprises 2 major groups: 1) the Assinica Group at the base and 2) the Broadback Group overlying the Assinica. The Assinica Group mainly comprises massive and tholeiitic pillow basalt flows. The Broadback sedimentary package comprises sandstones, polymictic conglomerates and mudrocks. The Frotet-Evans belt is metamorphosed to the upper greenschist facies. In this region, the volcanosedimentary belt is folded in an E-W syncline, which is displayed by E-W foliation with a steep dip towards the west. The Frotet-Evans belt is enclosed by a granitic-gneissic complex and has been intruded by posttectonic granodiorite and tonalites plutons.

The Sirmac deposit is a rare-metal bearing Pegmatite complex. The Sirmac pegmatite is a rare-element granitic pegmatite. The ore bodies comprise mainly sills and some feeder dykes are also present. The spodumene-rich pegmatites display typical zoning to varying degrees – an albite wall zone at the contacts followed by an intermediate zone containing mostly feldspar, quartz, mica and spodumene, followed by a spodumene-quartz-rich core zone. Many core zones are present and the mineralogy is the same which occurs as large crystals of spodumene (up to 30 cm) contained in a quartz-feldspar matrix, sometimes with accessory minerals like tourmaline and apatite. The presence of beryl was also observed in the margin of some core ........

The proposed mining project would see the extraction of 321,000 metric tonnes of mineralized material and 873,000 metric tonnes of waste during a 4-year period.

Open pit quarry method
The quarry operations method for the project is a simple drill, blast, muck and ship method. The work will be done 6 months per year from May to October. The waste rock will be drilled, blasted and stockpiled on a designated area on the property. The mineralized material will be drilled on a tight pattern and blasted. It will be stockpiled on the property and transported by trucks on a regular basis to a pad in Chibougamau close to the railway.

The benches will be 6 meters high and probably the drill holes will be of 115mm diameter depending on the chosen contractor.

Phase design
The project is designed to mine an average of 100,000 metric tonnes of mineralized material for year 1,2 and 3 and the remaining 21,000 metric tonnes for year 4. For the waste, for year 1 and 4 an amount of 130,000 metric tonnes per year will be mined out and for year 2 and 3, 307,000 metric tonnes per year.

Thus, for the first 4 years a total of 1,194,000 metric tonnes will be mined over a period of 6 months per year.

It is important to mention that a first 49Kt at 1.82% Li2O of measured and indicated mineral resources can be extracted without stripping in pit #1. GoldMinds elected to use the average grade of the mineral resources in the 4 pit design to ........

The Sirmac calls for a direct shipping of mineralized material without beneficiation. The base case is EXW Chibougamau while there is an alternative scenario with mineralized material shipped to the port of Saguenay, the FOB Saguenay scenario. Nonetheless, the testing shows the Sirmac pegmatite #5 Dike is suitable to produce a spodumene concentrate grading 6% Li2O and above. As the mineralized material is to be sold as a Direct Shipping mineralized material similar to some (DSO) iron projects, the recovery will depend of the company and plant which will process the material.
