Water from mine near Aspen to be tested with dye

ASPEN – The Colorado Division of Reclamation, Mining and Safety is teaming with the U.S. Forest Service to test the water from the Hope Mine near Aspen to see if it is running through waste piles.

Nontoxic, biodegradable dye will be placed in the water by scientists on May 9, according to an announcement by the Forest Service. The water flows underground from the mine to Castle Creek. The fluorescent dye will be visible for several hours before dissolving.

“The hope is that the dye will help determine if it’s being carried through the mine waste pile and how it is ‘transported,'” the Forest Service said.

Hope Mine is located five miles south of Aspen in the Castle Creek Valley.

“The Hope Mine began operation in 1921,” the Forest Service statement said. “One hundred fifty-eight and a half tons of silver ore was sold with an average of 70 ounces of silver per ton. Ore was taken to Aspen by wagon and shipped by rail to the Arkansas Valley plant in Leadville for processing.”
