Oposura Project
• Oposura mineral resource drill-out completed with 157 holes totalling 10,112m, with assay results received for 130 holes
• Original drill program expanded by an additional 40 drill holes (3,000m) to enlarge
resource area and increase drill hole density
• Good height and grade continuity of horizontal mineralisation confirmed – favourable
for initial extraction by open pit followed by room and pillar underground mining
• Initial mineral resource estimate expected in June 2018
• Positive metallurgy significantly reduces processing and marketing risk:
 Zinc recovery of 85.6% achieved producing a 57.2% zinc concentrate grade
 Lead recovery of 84.0% achieved producing a 61.4% lead concentrate grade
 Full elemental assays confirm clean concentrates
• Scoping Study / Preliminary Economic Assessment progressing well and on track
