The Moblan property is located in a world-class lithium-rich mining province, in the Eeyou Istchee Baie-James territory.
Applications for the use of land for the processing plant and the mine waste storage facility have already been submitted and are under evaluation by the authorities. The filing of the closure plan is planned for 2024. Financial assurance will be required upon approval of the closure plan. Other permit applications will be submitted upon approval of the ESIA. The Environmental and Social Impact Assessment (‘ESIA’) is underway. |

Summary:
The Property is located in the Frotet-Evans greenstone belt (‘FEGB’), which forms part of the Archean Superior Province. The geology of the Moblan Property is dominated by a large north-east trending gabbro, bordered to the north-west by mafic volcanics and lesser sedimentary rocks. The Archean bedrock is locally covered by glacial tills which typically do not exceed 3 to 4 metres in thickness.
The gabbro is the main host rock for lithium bearing pegmatite mineralisation. The pegmatites are of the albite – spodumene class of LCT (lithium-cesium-tantalum) pegmatites. Four pegmatite clusters are recognised, forming a series of stacked pegmatite dykes of variable thicknesses.
The Properties host several mineral occurrences and showings. These (and other adjacent) occurrences highlight the strong potential of the area for (i) Li pegmatite deposits; (ii) Cu-Zn VMS deposits; (iii) Au orogenic quartzcarbonate veins and disseminated sulphide deposits; (iv) Ni-Cu-PGE magmatic sulphide deposits; and (v) Au-Cu porphyry systems (e.g., Troilus Gold).
The economic potential of the Moblan Property is for lithium mineralisation (spodumene pegmatites). Lithiumbearing pegmatites were grouped into four (4) dyke swarms: Main, South, Inter and Moleon. Each corresponds to a series of stacked lithium-bearing dykes of variable thicknesses.
The Main group comprises 21 lithium pegmatite dykes oriented E-W and dipping gently to the north (N280°/-20°). This sw ........
Summary:
Mine Design
The Project will be mined by open pit methods using a conventional excavator and truck fleet. The final design comprises two open pits. The Moleon Pit encompasses the Moleon domain, and the Main Pit encompasses the Main, Inter and South domains.
The Main, Inter and South geological zones merge into a single final Mine design named Main Pit. The Moleon Zone will require a separate pit design and access.
The optimal depth of the Main Pit from the highest topographic point mined is 200 m. The optimal depth of the Moleon Pit is 130 m. Final designs are based on the optimised pit shells. Pit design is based on geotechnical, geomechanical, and hydrogeological studies combined with considerations and mine fleet equipment.
Mining Fleet
The owner operated production fleet consists of three 7 m3 backhoes, six 92 t mine trucks, and three 100 mm to 152 mm drills with remote capabilities.
Mine Schedule
A total of 114.1 Mt will be mined from the pits over a 21.1-year LOM, including 4.1 Mt of overburden, 75.4 Mt of waste rock and 34.5 Mt of ore at a grade of 1.36% Li2O. The total calculated stripping ratio (‘SR’) is 2.3.
