Strashimirite is an uncommon secondary copper mineral formed by oxidation of
arsenites in the oxidation zone of copper-arsenic bearing mineral deposits,
associated with tyrolite, cornwallite,
azurite, malachite and
At the Zapchitsa copper mine, Bulgaria, strashimirite occurs late in the sequence with azurite, olivenite, malachite and euchroite, and it replaces tyrolite and cornwallite (Dana, AM54.1221).
At the New cliffe quarry, Stanton under Bardon, Leicestershire, England, UK, strashimirite has been found with malachite (RES p197).
At the San Rafael mine, Nye county, Nevada, USA, strashimirite occurs with chrysocolla pseudomorphs after olivenite and minor cornwallite (R&M 85.6.523).
