To Whom It May Concern: Pursuant to the provisions of Section 1.6 of the Mined Land Reclamation Board's rules, Homestake Mining Company wishes to provide notice of temporary cessation of operations at its Bulldog Mountain Mine in Mineral County, Colorado. Late last year, operations were curtailed to periodic operation of the mill. Toward the end of the year, mill operations involved only activated carbon regeneration. By approximately October 3, 1988, we had reduced staff to those necessary for care and maintenance of the mill, the mine, and the surface facilities along with periodic carbon regeneration. For purposes of Rule 1.62, we believe the 180-day period from the time of effectively temporarily ceasing operations will end on or about March 31st of 1989. The operations have been temporarily curtailed because of low silver prices. We intend to maintain the Bulldog Mountain, and associated properties, until such time as economic conditions permit us to return to active mining. Approximately 1,200,000 tons of ore remain. The ore contains an average of 14.2 ounces of silver per ton and 1.9 percent lead. Mining and beneficiation operation could be restarted with little additional preparation other than machine and equipment startup.

We have adequate equipment on-site and available from contractors and other Homestake operations to maintain erosion controls and conduct necessary repairs.
