Alto Group acquires historic Great Excelsior Mine in Washington
Alto Group Holdings, a mining and commodities trade company headquartered in New York, announced on Monday the acquisition of the Great Excelsior Mine in Washington State.
The Great Excelsior Mine, located in Washington State, was a gold-silver producer which was forced to close in 1918 due to falling metal prices and a shortage of supplies. This mining property has been explored by numerous mining companies over the years.
