Collaboration with Miramar Mining Corp., Indian and Northern Affairs Canada and University of Western Ontario Borden Basin Project Northern Baffin Island Objectives: .Resolve stratigraphy/sedimentology of complex carbonate-shale succession exerting prominent facies control on mineralisation .Regional metallogeny, structural, stratigraphic controls on mineralisation Field Work: 2003, 2004, 2005 Project Leadership: Elizabeth Turner (C-NGO) Geologic Context: Numerous base metal showings in unmetamorphosed Mesoproterozoic aulacogen (300 x 200 km) with considerable syndepositional faulting, but no known post-rifting event significant enough to drive large volumes of metalliferous fluid .Nanisivik Mine 17 Mt 10% Zn+Pb Tremblay Peninsula Borden Basin Project Early Results: . Strong facies control on mineralisation – most showings hosted by organic-rich, Fe- rich basinal carbonate rhythmites deposited in deep anoxic basin . Strong structural control on mineralisation – commonly on low-displacement adjustment faults rather than prominent rift-faults.
