The Bomboré gold deposit is the principal gold mineralization of potential economic significance found to date on the Property. It is located in an area that is principally prospective for orogenic gold deposits. Similar to gold deposits found elsewhere in late Proterozoic Birimian terrains of West Africa, the Bomboré gold deposit exhibits a structural control and hydrothermal activity. It is a large tonnage, low grade system that has similar characteristics to other Birimian gold deposits such as Kiaka in Burkina Faso, Damang, Yamfo-Selwi and Obuasi in Ghana, and the Sadiola deposit in Mali.

Hydrothermal deposits are typically late orogenic deposits and exhibit strong relationship with regional arrays of major shear zones. The gold mineralization is typically associated with a network of quartz veins containing subordinate amounts of carbonate, tourmaline, sulphides, and native gold. In these deposits, the gold is typically free milling. Alternatively, the gold mineralization can also be associated with disseminated sulphides in strongly deformed alteration zones. In the latter case, gold may be free milling but also locked in the sulphide lattice structure and refractory. The Bomboré deposits are stratabound disseminated sulphide bodies preferentially hosted in the meta-gabbro and meta-argillite lithologies, which are interpreted to have acted as preferential gold traps during a syntectonic deformation and metasomatic event due to their chemical and rheological c ........

The Bomboré mine will be developed as an open pit operation mining oxide and sulphide material from over 60 separate pits of variable size and depth across a mineralized zone approximately 12.2 km long and 3 km wide. The oxides include the regolith, upper saprolite, lower saprolite, and upper transition weathering units. The oxide material can be readily excavated in situ (free-dig material). The sulphides include the lower transition and fresh rock weathering units, which will require a varying degree of drill and blast prior to being loaded onto trucks.

Mining within the Restricted Zones targets the free-dig oxide material and will only take place during the dry seasons. Mining, backfilling, and rehabilitation of the pits within these areas is to be fully completed prior to re-establishing river flow by the start of the next wet season.

Mining of ore and waste will be contracted out with an owner’s team responsible for site management, grade control, and mine planning activities. Mining of oxides will be undertaken with 4.5 m3 hydraulic excavators (i.e. Komatsu PC850) and 30-50 t highway dump trucks. The sulphides will be mined using a separate fleet (i.e. Komatsu PC1250 and 50 t Volvo FMX rigid body trucks) to account for the increased density, abrasion and hardness of the material.

ROM ore will be hauled to the process plant and low-grade material hauled to the low-grade stockpiles.

Separate waste rock dumps (WRD) will be constr ........
