     KEYSTONE, S.D. (AP) - Work has resumed at a gold exploration drilling site in western South Dakota where a leak occurred last week.
 
     The site was shut down when bentonite leaked into Battle Creek near Keystone. Bentonite is a claylike material used as a drilling lubricant. State officials do not expect any environmental damage.
 
     Mineral Mountain Resources Ltd. of Vancouver, British Columbia, is exploring for gold in the area.
