Faulted, slickenlined massive sulfide, Bathurst, New Brunswick, Canada

Whereabouts

I collect this in 1968 while mapping underground at the Caribou mine.  In specific, there was a location in the mine where the massive sulfide layers were cut and displaced by a fault zone, creating an offset of more than 30 m.  The stiff sulfide layers were fractured and broken, and locally polished and slickenlined.  I like the fact that this is naturally polished metal.
