Precieux Gold Mining - PROJECT GEOLOGY
Precieux Gold Mining Project
Our Gold Project covers an area of more than 370 km², situated along the Casa Berardi Deformation Zone (“CBDZ”) within the prolific Abitibi Greenstone Belt (“AGB”). It belongs to the syenite-associated gold class of mineral deposits, which includes Beatty (>5.6Moz Au), Holt-McDermott (>1.3Moz Au), and Australia Malartic (>17Moz Au) in the AGB. The area is also prospective for the more typical AGB orogenic style (structurally controlled gold-quartz veins and veinlets) of gold deposit as well as for volcanogenic massive sulphide (“VMS”) deposits.
It consists of a northern corridor of relatively well preserved tuffs of felsic to intermediate compositions; the central 3 km wide Douay-Style Mineralization (“DSM”) corridor enclosing the CBDZ with a mix of syenitic porphyries, basalts, felsic volcanic rocks and iron formations, and gold-hosted shear zones; and a southern corridor of mostly basalts with siliceous-chemical sediments and chlorite-sulphide bearing feeder-pipes, both typical of VMS systems. The volcanic stratigraphy trends WNW to ESE whereas the major regional fault zones trend E-W. Existing drill data shows multiple higher-grade zones, including Douay West, within and near an elongated body of syenite porphyry over an area of at least 6.5 x 2 km. In addition, there are further poorly explored known and possible syenite bodies elsewhere on the property.
Alteration assemblages and micro-fracturing in brittle rocks hosting narrow veinlets of quartz-carbonate with pyrite are associated with higher gold values generally above 5 g/t gold over metric intervals within the DSM. Fractured syenite containing fine pyrite veinletsin addition to disseminated pyrite, encompassing altered basalt fragment and magnetite-rich "iron formation" yield 100 ppb to 1 g/t gold over decametric to hectometric intervals
