Note on the mineral list: the villyaellenite originally reported from here turned out to be miguelromeroite, the Mn analogue of sainfeldite.
Recent analysis led to the following results:
Actinolite: Conf. meth.: EDX (typical composition, most Fe is assumed to be divalent, because of green color of the crystals), Ref.: by Joy Desor and Gerhard Möhn

Atacamite: Conf. meth.: EdX and visually (crystal shape), Ref.: by Joy Desor and Gerhard Möhn
Babanekite: Conf. meth.: EDX, Ref.: by Günter Blaß, Cu-dominant solid solution with Manganohörnesite, Erythrite and Annabergite
Calcite: Conf. meth.: visually and chemical tests
Chalcopyrite: Conf. meth.: visually
Chrysocolla: Conf. meth.: visually
Cinnabar: Conf. meth.: EDX, Ref.: by Günter Blaß
Connellite: Conf. meth.: chemical tests,Ref.: by Gerhard Möhn, chemical test:positive: Cu2+, Cl-, SO42-negative: CO32-
Copper: Conf. meth.: visually, tenacity.malleable
Covellite: Conf. meth.: visually and immersion in water->color turns to violet
Cryptomelane: Conf. meth.: chemical tests,Ref.: by Gerhard Möhn, massive hard Mn-ore chemical test:positive:K+,Mn-negative: Ba2+, Pb2+
Diopside: Conf. meth.: EDX, cleavage, hardness and crystal shape, Ref.: by Joy Desor and gerhard Möhn
with Fluorapatite and Actinolite in a crack of the rock
