Here are two pieces of historic interest: a cut 6.5 x 3.8 x 0.5 cm slab and an uncut piece 6.5 x 4.0 x 3.5 cm. Although huntilite is now discredited, in 1879 it was thought to be a new mineral species and was named after Prof. T. Sterry Hunt. It has since been proven to be a mixture of primarily nickeline and antimony-rich silver, with minor skutterudite, and sphalerite. Also associated with the huntilite dendrites are small amounts of fine grained galena which impart a sparkle to freshly broken dendrites. On the weathered surface can be found annabergite staining due to decomposition of the nickeline. All of these minerals are in a matrix of pink dolomite and white quartz. For a detailed, historic description see Engineering and Mining Journal, Volume 34 - Page 322, December 1882 at this link http://books.google.ca/books?id=3kfnAAAAMAAJ&pg=PA322&dq=huntilite&as_brr=3&cd=1#v=onepage&q=huntilite&f=false
