Shear hosted gold

I spent a week writing a report on a 2008 drill program completed on what was Carina’s Black Lake property.  The property is predominately underlain by mafic-intermediate volcanic rocks while gold mineralization occurs within  quartz-carbonate-sulphide veins that occur within highly altered northeast trending shear.

 

I spent a week writing a report on a 2008 drill program completed on what was Carina’s Black Lake property.  The property is situated in the Abram-Minnitaki Greenstone belt and is largely underlain by interbedded mafic to intermediate flows & flow breccias and their volcaniclastic equivalents with subsidiary iron formation and conglomerate.  Gabbros, granodiorite and quartz-feldspar porphyrytic dykes and plugs are also present in smaller amounts. 

Gold on the property occurs most often as coarse often visible flecks within quartz-carbonate-sulphide +/- tourmaline veins and stockwork systems that are hosted within highly sheared and altered northeast trending fault/shear systems.  The veins typically contain small amounts of pyrite, chalcopyrite, galena and arsenopyrite.
