Almost all Pushtun tribes in Duki including Nasar, Tareen and Luni participate.
The Nasar tribe has a large share, and is considered to be the master miners and businessmen.
Kingri sub-Tehsil of Musakhel District is located on the borders of Punjab Province.
In the early 1980s coal exploration started, but ended due to poor roads.
In President Musharraf's regime, the roads from Fort Minro to Kingri were improved.
Aram in Kingri has excellent coal and charcoal reserves, available at a depth of 30 feet.
