Lapis lazuli-bearing skarn zones, up to 300 m long and 8 m thick, hosted in Archean gneiss, carbonaceous marble, calciphyre and crystalline schist that were intruded by alaskite granite and mafic dykes.

The deposit is worked by several mines which are numbered. Ladjuar Medam is a generic name which just means "lapis lazuli mine". Thus, it may refer to any of the mines in this area.

Located in Kuran Wa Munjan District.

See article on mining lapis lazuli at Sar-e-Sang in the 1830's.
