Precious metals tests performed on samples from the Empire open pit deposit using non-toxic ammonium thiosulfate ("ATS") reagent resulted in high gold recoveries of 97.8% and 97.7%, and silver recoveries of 69.8% and 78.2%, respectively
-- ATS reagent consumption comparable to sodium cyanide in back-to-back bench scale tests
-- This development presents the opportunity to bring forward precious metals production as there would no longer be the requirement to permit a cyanide operation
-- Pilot scale test plant now being prepared at the laboratory in Salt Lake City before commencing small scale pilot testing at Empire
