Baryte, Mimetite

This is a rarely seen and highly aesthetic matrix specimen of baryte and mimetite from the famous Ojuela Mine in Mapimí, Durango, Mexico. Barite–mimetite combinations are uncommon from this locality, and this particular piece stands out for its exceptional balance. The specimen features sharp, well-formed golden-yellow baryte crystals perched on a gossan matrix, accented by associated mimetite. It is one of the more striking and high-quality examples of Ojuela baryte encountered, representing rare and desirable combination material from this prolific Mexican 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.
