Best known for the Type species Ajoite and Papagoite, the New Cornelia mine in Ajo District, Pima Co., Arizona is also famous for having produced some excellent Chalcotrichite - the hair-like variety of Cuprite. Many of the best Chalcotrichite specimens were collected by William “Jim” Thomas, who was an engineer at the New Cornelia mine for 38 years. His position allowed him to collect minerals during the active mining operation. Although not specifically recorded as such, this rich very large miniature specimen from Paul Matt is almost identical to one sold by Rock Deco (Paul Matt and Barbara Matt - Tucson, Arizona) from William “Jim” Thomas suggesting the same source. The Chalcotrichite is finely crystallized, but under magnification it can be seen to be velvety masses of matted red hair-like microcrystals. A classic from the now closed New Cornelia mine.
