Operating from 1927 to 1932, Lucky Queen was the highest-grade silver producer in the Keno Hill District -- and one of the highest-grade silver mines in the world -- producing 11 million ounces of silver from 123,500 tons of ore for an average recovered production grade of 88.7 ounces of silver per ton.
Rehabilitation and redevelopment of the historic underground mine began in April 2011, with the aim of accessing underground drilling targets by the end of 2011. In August 2011, Alexco announced an estimated resource at its Lucky Queen property of nearly 4.9 million Indicated plus 2.8 million Inferred ounces of silver. Metallurgical testing and preliminary mine planning and engineering studies were initiated in 2011.
Development of the ore body began in 2012. Underground rehabilitation of 1,200 meters of the old mine workings has been completed toward accessing the first new area of deposit, with 100 meters of development drift driven during the year. Although a firm date has not yet been set for production startup, as supplemental feed to the Keno District Mill, Lucky Queen is expected to be operated on an as-needed basis to ensure optimal mill feed blending for the best overall economic results.
