Lucky Queen Overview

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 112,096 tonnes of ore for an average recovered production grade of 98.3 ounces of silver per tonne.

In March 2017, an updated Preliminary Economic Assessment reported a potentially mineable 81,000 tonnes at an average silver grade of 1,206 g/t (“grams per tonne”) - a total of 38.8 oz/t - at Lucky Queen. Total resource at Lucky Queen comprises 4.9 million indicated ounces of contained silver and 3.9 million ounces of inferred mineral resources of contained silver.

Achieving production, the fully permitted Lucky Queen deposit is expected to be used as supplemental feed to the Keno District Mill, on an as-needed basis to ensure optimal mill feed blending for the best overall economic results.
