This article is in a pre-construction phase.Someone is needed to work on this article which contains a few preliminary notes.
1. The localities need to be brought into conformity with mindat locality strings if necessary, reversed and made bold.
2. If image links appear below they need to be embedded in the article. If none are present the Mindat image bank needs to be searched for images of this mineral and the better ones and their localities need to be placed in the article.
3. The captions for the images need to be added.
4. The images need to be tweaked so that they look nice. This last bit is tedious and requires some little artistry.

By far the largest crystals are from Austria but aschamalmite also is found at Granite Gap, Hidalgo County, New Mexico, USA.
Austria
Salzburg, Untersulzbach Valley, Ascham Alm. “The mineral occurs as lead-gray, lath-like crystals to 5 cm in length or thick, slightly bent plates up to 1 cm2. Most crystals are heavily altered to a mixture of bismutite and other as yet unidentified phases. Exsolution lamellae of galena and cosalite are commonly present. Luster metallic, cleavage (001) perfect… Aschamalmite is found in mineralized, alpine-cleft veins cutting through gneiss near Ascham Alm in the Untersulzbach Valley associated with quartz, albite, adularia, calcite, chlorite and galena.”1

There are a few other localities within the Hohe Tauern range that produced similar material of comparable quality, among them the Leckbachrinne (this find has been documented in Lapis magazine).

If we can get some pictures and find someone to tell us about the find, we will put it in.
