In order to provide raw materials such as lime and salt,Semnan Soda Ash CO.(S.S.A.C.O),has started to verify ,explore and planing of mine's sources from 2003 . During this stage ,the 4 lime mines have been identified and registred knoen as :AHAK MARAB ,JAHAN NAMA,ROYAN KOUH and LITO .the derivation opration from AHAK MARAB and JAHAN NAMA ,whit the capacity of 22 milion tons is one of process.
