Conichalcite, CaCu, is a relatively common arsenate mineral related to duftite. It is green, often botryoidal, and occurs in the oxidation zone of some metal deposits. It occurs with limonite, malachite, beudantite, adamite, cuproadamite, olivenite and smithsonite. 

Olivenite is a copper arsenate mineral, formula Cu₂AsO₄OH. It crystallizes in the monoclinic system, and is sometimes found in small brilliant crystals of simple prismatic habit terminated by domal faces.
