The origins of silver-bearing, polyelement vein associations in the Great Bear Lake region and elsewhere in the world might be traced back to possible organic-rich, Precambrian sedimentary protoliths. These protoliths could have yielded a characteristic spectrum of elements to hydrothermal systems d...
