Mining activity in the lower levels resumed after a four-year process to rehabilitate, improve and re-commission the fine following its closure by previous operators in 2001. Sterling said that with renovation of the Silver Summit hoist and rehabilitation of the Silver Summit shaft to the 3,000 ft level, the mine’s secondary escapeway system is now complete. Sterling crews are resuming mining activities from 2,700 ft and 3,100 ft level workplaces idled at closure. Ores from these levels, at closure, averaged 23.6 oz of silver per ton. In addition to mining activities being resumed on the lower levels, crews are also processing material from drifting and exploration.
