Supergene minerals are not common, nor are they rare at Santa Rita, New Mexico. Kerr (1950,307) reports the presence of cuprite, melaconite, native copper, chrysocolla, machite and azurite. There is also smithsonite present.
The physical appearance of the mineral, coupled with preliminary determinations of the indices of refraction, gave a rough correspondence with dihydrite (Larson and Berman, 1934, 135). However, enough discrepancy existed to warrant taking powder and Weissenberg X-Ray pictures. From these it was evident immediately that the specimen was a new mineral species.
