Fascinating trigonal crystals with a hexagonal outline stacked in parallel togethor in small groups to 2.5mm. This is an excellent specimen of this rare sulfate found only at this locality, the Huanuni mine. Nikischerite is named in honor of Tony Nikischer.

Tony Nikischer owns and operates Excalibur Minerals Corporation in Charlottesville, NC. Tony has been a main stay in the mineral market for 50 years! Excalibur is the largest supplier of rare minerals in the world and has in-house analytical equipment. Tony serves as Chairman of the Board of The Hudson Institute of Mineralogy. He is also the publisher of Mineral News, a monthly periodical devoted to mineral collecting.

The original paper on Nikischerite was published in the Mineralogical Record in 2003 and can be read by clicking this link.

Peisleyite, pronounced peez'-lee-ite, is a one-locality mineral found only at Tom's quarry since 1982. It is a dull, white, chalky massive piece. It has yet to be found in distinct crystals. Please see the prov. tab for a scan of the signed label.

From Mindat: "Peisleyite was named in 1982 in honor of Vincent Peisley (b. 1941, died 6 May 2021), mineral collector from Brahma Lodge, Australia who collected the first specimens.

Both the dark green to grass green globular crystals as well as the yellow fibrous and acicular crystals on this specimen is Plimerite. Plimerite occurs in four worldwide localities as reported thus far. This is a rich specimen. 

Named after Ian Pilmer, an Australian Professor of Mineralogy at the University of Adelaide and an Emeritus Professor of Earth Sciences as the University of Melbourne who made large contributions to ore deposit geology, particularly the geology of the Broken Hill deposit in New South Wales, Australia.

Orange-brown to yellow to colorless equant or tabular crystals 1mm. The crystals display perfect basal cleavage giving the appearance of a micaceous mineral but is not. This is a very nice specimen for the species.

Named for author of “The Complete Book of Micromounting” and contributor to the mineralogical studies of Mont Saint-Hilaire, Quintin Wight. Notable localities for Quintinite are found at one of the two co-type localities at the Jacupiranga mine in Sao Paulo in Brazil where it occurs in a carbonatite with gonnardite and donnayite.

Rongibbsite crystals to about 0.3mm growing on clear Quartz crystals and on the fringes of the small vug. 

Rongibbsite is named after Ron Gibbs an eminent mineralogist of the southwestern US. Ron brought many rare phosphates and arsenates to market and personal collections. He is coauthor of the book "Mineralogy of Arizona" 4th edition. He also authored the book "Agates and Jaspers" in 2009. His profession as a mining engineer landed a job at the famous New Cornelia mine in Arizona and later in Tyrone and Silver City, New Mexico. You will always see Ron at the New Mexico Mineral Symposium and of course the Tucson show.

Ron along with Joan Beyer wrote a paper on Granite Gap, Hidalgo Co., NM. Their collecting culminated in many new occurences of minerals from this locality. The offiicial citation is: Beyer, J., Gibbs, R. (2002) Minerals of the Granite Gap Mines, Hidalgo County, New Mexico. Rocks & Minerals: 77(5): 298-305.
