This mineral was discovered in Zapachitsa (Zapacica) copper deposit, [Svoge](/source/Svogue_Municipality), [Sofia Oblast](/source/Sofia_Oblast), [Bulgaria](/source/Bulgaria) in 1960, by Bulgarian mineralogist [Jordanka Minčeva-Stefanova](/source/Yordanka_Mincheva_-_Stefanova). She named it after [Strashimir Dimitrov](/source/Strashimir_Dimitrov_(mineralogist)) (1892–1960), Professor in Mineralogy and Petrography at [Sofia University](/source/Sofia_University_%22St._Kliment_Ohridski%22) "St Kliment Ohridski", Bulgaria.<ref>{{cite journal |url=http://rruff.info/uploads/AM54_1218.pdf |first=Michael |last=Fleischer |author-link= Michael Fleischer (mineralogist) |year=1969 |title=New Mineral Names |journal=The American Mineralogist|volume=54|page=1221}}</ref> The [International Mineralogical Association](/source/International_Mineralogical_Association) approved it as a new mineral in 1968.<ref>{{cite journal |url= http://articles.adsabs.harvard.edu/full/seri/CRABS/0054//H000049.000.html |first1=D. |last1= Stoilova |first2= J |last2= Minčeva-Stefanova |year=2001   |title= Infrared Spectroscopic Study of Strashimirite |journal= Comptes Rendus de l'Académie Bulgare des Sciences |volume= 54 |issue= 8 |pages= 49–52}}</ref>

It occurs as a secondary mineral phase in the oxidation zone of copper arsenide deposits. It occurs associated with [tyrolite](/source/tyrolite), [cornwallite](/source/cornwallite), [clinoclase](/source/clinoclase), [euchroite](/source/euchroite), [olivenite](/source/olivenite), [parnauite](/source/parnauite), [goudeyite](/source/goudeyite), [arthurite](/source/arthurite), [metazeunerite](/source/metazeunerite), [chalcophyllite](/source/chalcophyllite), [cyanotrichite](/source/cyanotrichite), [scorodite](/source/scorodite), [pharmacosiderite](/source/pharmacosiderite), [brochantite](/source/brochantite),
[azurite](/source/azurite), [malachite](/source/malachite) and [chrysocolla](/source/chrysocolla).<ref name=handbookofmineralogy/>

Although it remains quite rare, strashimirite has subsequently been identified in a number of locations including: Novoveska Huta in the Czech Republic; on the west flank of Cherbadung (Pizzo Cervandone), Binntal,
Valais, Switzerland; in Kamsdorf and Saalfeld, Thuringia, Germany; the [Clara mine](/source/Clara_mine), near Oberwolfach, Black Forest, Germany; in the Richelsdorf Mountains, Hesse, Germany; Cap Garonne mine, near le Pradet, Var, and Triembach-au-Val, Haut-Rhin, France; Wheals Gorland and Unity, Gwennap, Cornwall, England; the Tynagh mine, near Loughrea, Co.
Galway, Ireland; the Majuba Hill mine, Antelope district, Pershing Co. Nevada, US;  and the Centennial Eureka mine, Tintic district, Juab Co., Utah, US.<ref name=handbookofmineralogy/>
