Nanisivik Mine, Arctic Bay, Baffin Island, Nunavut, Pyrite and Sphalerite

The Nanisivik Mine, a significant zinc mine was, during its operating days, the second-most northerly base metals mine in the world. WAY up there! It has been closed for over a decade now and has the site has been rehabilitated so that little trace of the mine remains now.
The Nanisivik mine is famous for unusual pyrite crystals. Pyrite crystals often show combinations of the cube, octahedron, pyritohedron, dodecahedron and trapezohedron. In addition, many of the crystals are actually pseudomorphs after marcasite or oriented overgrowths of pyrite on pyrite pseudomorphs after marcasite! All of these factors result in VERY interesting pyrite crystals habits. Many of these specimens are very similar to the ones pictured in the Mineralogical Record Volume 21, Number six, Pages 515-534.
Besides the interesting pyrite crystals, very nice specimens of sphalerite (the ore mineral of zinc at the mine), quartz, dolomite and calcite were recovered during mining operations. Here are some excellent examples!

  • A great looking cluster of wide-bladed pyrite pseudomorphs after marcasite. The form of the marcasite is clear with the striations of the marcasite well preserved. Lustrous and golden. Looks better than in the photo!

  • This is a cluster of pseudomorphs of pyrite after marcasite. The pyrite has replaced the two-membered, bladed type of marcasite twin and so we see elongated, bladed pseudos with and oriented overgrowth of small pyrite crystals. There are sa few crystals missing from the front of the specimnen but, in reality, the photo was taken at too low of an angle. All of the crystals further back are complete and it is a handsome specimen!

  • A very nice "ore" specimen from the Nanisivik mine! The piece is mostly sphalerite with lots of almost black sphalerite crystals lining a vug at the top of the specimen, partially covered by sharp calcite crystals, mostly smaller but with one particularly large crystal. Beautiful!
