The mineralization consists of polymetallic (copper, zinc, lead), oxidized, gold-bearing veins, up to a metre in thickness and a decameter in length, in close proximity to mafic sills and interbedded in Lower Cambrian limestone (marble) (Figure 3).
Most gold-bearing veins occur along a NNW-trending corridor that can be traced from our Azegour mine. Gold is found as inclusions in altered iron oxide, carbonate, quartz, arsenopyrite or in muscovite. Their unoxidized counterparts contain pyrite, pyrrhotite, arsenopyrite and malachite with rare galena and chalcopyrite.
From 2009 to 2011, Maya carried out geological mapping, trenching and channel sampling resulting in the identification of 57 mineralized sites. Nearly 6,000 metres of core drilling was carried out on mineralized targets identified through ground-based induced polarization (IP) and magnetic geophysical surveys.
An inferred mineral resource of 819,769t grading 12.98 g/t was estimated using the data base provided by the Az and TRN zones.
*A cut-off grade of 1.74 g/t Au was used for a thickness of 1.55 m (dilution= 0 g/t Au). Note that inferred mineral resources are not mineral reserves and do not have demonstrated economic viability.
