Timok Project Review

"Timok remains the Company's number one priority to add shareholder value. We continue to achieve our key milestones including completion of infill drilling and progressing technical studies in support of the Timok project pre-feasibility study. We are on-track to commence decline development during 2017 and remain on-track to deliver the pre-feasibility study," stated Chief Executive Officer, Cliff Davis.

"We are making continued improvements at Bisha which is translating into improvements to our operating income quarter over quarter," stated Cliff Davis, "With copper sales expected during Q2 2017 and less bulk concentrate, we expect even further improvements for the remainder of 2017. We are also pleased with higher than planned quarterly zinc and copper production, which means the Company is on track to meet annual production guidance.  We continue to make incremental progress on all key performance indicators."
