Calcite, Dolomite, Marcasite

This excellent palm-sized specimen features a robust, golden scalenohedral calcite crystal prominently perched atop a dolomite matrix. The dolomite is lightly coated with microcrystalline marcasite. The specimen is in excellent condition with no damage, making it a unique and well-preserved example from this long-closed zinc mine.

The Nanisivik Mine, located on Baffin Island, Nunavut, was a zinc-lead operation situated 750 km (470 mi) north of the Arctic Circle. Opening on October 15, 1976, it was one of the most northerly mines in the world, producing sphalerite as its primary ore. The mine ceased operations in September 2002 due to declining resources and low metal prices.

This particular specimen has historical significance, having been purchased by Dr. Tarassoff at the first annual "Club de Minéralogie de Montréal" gem show in 1986. It serves as a fine representation of the mineral wealth once extracted from this remote Arctic locality.

This specimen comes from the collection of Dr. Peter Tarassoff, a prominent figure in mineralogy, particularly known for his work at Mont Saint-Hilaire (MSH). His diligent collecting and examination efforts have led him to be the first to identify at least 35 species and discover 12 new species, not only at MSH but also at other alkaline localities. Dubbed the "Dean" of Mont Saint-Hilaire collectors, Peter was honoured with the naming of the new species petarasite in 1980. He has authored or co-authored numerous mineralogical articles and has been a member of the Mineralogical Association of Canada since 1964. Additionally, Peter has volunteered at the Redpath Museum for the past 21 years, where he was formally appointed the Honorary Curator of Mineralogy. In recognition of his significant contributions to mineralogy, Peter was awarded the 2017 Pinch Medal
