Likasite is an IMA-recognized mineral species in the nitrate class, with the chemical formula Cu₃(NO₃)(OH)₅·2H₂O.
It crystallizes in the orthorhombic crystal system (space group Pcmn).
Key properties: specific gravity 2.96–2.98; optically biaxial.
IMA symbol Lik, grandfathered status — known before the IMA’s founding, named in 1955.
A rare secondary mineral found in the oxidized zone of copper deposits.
It is found associated with Cuprite, brochantite, malachite, copper, silver, buttgenbachite, gerhardtite, miersite, iron oxides (Likasi mine, Congo).
