Comstock Metals Ltd. reported metallurgical test work recently completed on sample materials from the Preview SW deposit. Test work has been completed at ALS Metallurgy of Kamloops B.C., in December 2017 under the direction of Jeffrey B. Austin, P.Eng and is a follow-up to previous testing completed in 2013. Test work in 2017 was focused on better defining the quality of gravity and flotation concentrates that are expected from the Preview project materials and providing preliminary test results for cyanide leaching of flotation concentrate. Combined gold recovery for both gravity and bulk flotation processes in the current test work is estimated at 82% for zone 103 and 89% for zone 104 and compares well with the previous metallurgical results of 2013. Cyanide leaching of flotation concentrates indicated that in excess of 98% of the gold contained in flotation concentrates could be extracted using industry standard cyanide leaching conditions. This test work better defines the potential processing options for the Preview project and indicates that gold recovery using gravity, flotation and concentrate leaching is possible. As well, flotation concentrates are shown to have sufficient quality to warrant evaluating the off-site processing alternatives of these concentrates in order to potentially simplify on-site processing. Optimization work is still required for the metallurgical process at Preview, but no significant metallurgical issues related to gold recovery have been identified from the work to date. The company is planning to conduct initial metallurgical testing on samples from the North Zone, located 2.5 km northeast of the Preview SW deposit where multiple high-grade gold zones were intersected in 2017 drilling.
