Project Geology & Mineralization

 
Regional Geology and Project Outlines 01112023
Fig. 1: General Geology of the Douay and Joutel Gold Projects. The Casa Berardi Fault Zone widens in the Douay area, with North and South strands merging to the east and the west. Note syenitic bodies several km to NE and NW of the Resource Area along the north strand of the Casa Berardi Fault Zone. The South strand of the Casa Berardi Fault Zone is also known as the Harricana Break. The Joutel Gold Project covers ~15 km of strike along this break.

The Douay Gold Project covers an area of more than ~357km² along the Casa Berardi Deformation Zone (“CBDZ”) within the prolific Abitibi Greenstone Belt (“AGB”). Douay belongs to the alkaline-intrusive-associated gold class of mineral deposits, which includes Beatty (>5.6Moz Au), Holt-McDermott (>1.3Moz Au), and Canadian 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.

The Douay project is underlain by a northern assemblage of mafic and felsic pyroclastic and sedimentary rocks (Taïbi Grp), a central assemblage consisting of basalts, co-genetic gabbros with lesser felsic volcanic rocks (Cartwright Hills Grp) intruded by the 6.5 x 2km Douay alkaline intrusive complex (syenite to monzonite, alkali gabbro and carbonatite) with its associated gold mineralization; and a southern assemblage consisting mostly of basalts (also Cartwright Hills Grp) with siliceous-chemical sediments and chlorite-sulphide alteration zones that may be associated with VMS style of mineralization. The volcanic stratigraphy strikes WNW to ESE whereas the major regional fault zones trend E-W or NW-SE. Existing drill data shows multiple higher-grade zones, including Douay West, within and near the Douay intrusive complex.  In addition, there are further underexplored known and possible syenitic bodies elsewhere on the property.

Fe-carbonate-albite-pyrite alteration assemblages may be associated with higher gold values, generally above 5 g/t gold. Fractured syenite containing irregular fine pyrite veinlets in addition to disseminated pyrite, encompassing altered basalt fragments and magnetite-rich zones typically yields 0.1 to 1.5 g/t gold or more over intervals from tens of metres to over 150m.

Gold mineralization appears to be associated with the following features:

  • Proximity of a major fault to provide a plumbing system and structural permeability.
  • Interlayering of different lithological units, especially mafic with felsic units with syenitic intrusions. These are thought to provide rheological contrasts to focus deformation, alteration and mineralization.
  • The presence of chemically favourable mafic units providing iron for sulphidation of mafic minerals.
  • The presence (for proximal style of mineralisation) or nearby (for more distal style) syenitic intrusions, as bodies, dyke swarms or narrow injections, interpreted to represent the source of metals and sulphur.
  • Sulphides averaging 2% but varying from trace to 5%.
