The mineralization zone on the Akasaba West property consists of a low-grade mineralized envelope characterized by the widespread presence of finely disseminated chalcopyrite; the mineralization is primarily contained within the quartz diorite unit.

The gold was thought to be associated with stratiformed disseminated to semi-massive lenses of pyrrhotite-chalcopyrite hosted in mafic lapilli tuffs and brecciated basalt altered with epidote- hornblend-actinolite related to contact metamorphism. The genesis of the deposit remains very controversial. Two master thesis present two different hypothesis. One of those masters (Lev Vorobiev, 1998) supports the hypothesis that the mineralization is emplaced during skarn development whereas the other the (Jeanne Lebel, 1987) was in favor a VMS genesis hypothesis. It is possible that the actual Akasaba deposit characteristics and geometry is a result of an overprinting of several gold mineralization events (hydrothermal, orogenic and skarn).

The Akasaba West project is expected to be mined over four years by open pit methods using a conventional shovel/truck operation. The mining rate is expected to be an average of 10,000 tonnes per day (waste and ore) and will feed the Goldex concentrator at a rate of 2,800 tonnes of ore per day.

Gold from Akasaba West will be first recovered in the Goldex gravity separation circuit where 20% of the gold is expected to be recovered. The remaining recoverable gold and copper will be recovered in the Goldex bulk sulphide flotation concentrate. The sulphide bulk concentrate from Goldex Deep and Akasaba West will be transported by truck to the LaRonde mine where the remaining gold and copper will be recovered through the LaRonde copper flotation circuit.
