The Achin magnesite deposit occurs in Nangarhar Province at the northern foot of the east-west trending Spinghar Range of mountains, 70km SE of Jalalabad. The deposit is located about 10 km south of Achin and can be divided into two distinct parts: The northwestern unit is composed of a large, oval-shaped magnesite body accompanied by several small ones. The south- eastern part consists of several, relatively small, lensoid magnesite and talc bodies, which are elongated in NW-SE direction. The host rocks of the magnesite and talc bodies are Proterozoic metasedimentary and metavolcanic rocks, predominantly dolomitic marble.
A general study in the 1970’s demonstrated the potential of the area and estimated resources for the Achin magnesite-talc deposit to 66 million tonnes of magnesite and 5.5 million tonnes of talc.
