RESULTS
Segovia
• Our primary focus is our Company mines which provided 95% of Segovia’s total H1‐2018 gold production.
• Improvement in head grades and tonnes mined in the Providencia mine has been key catalyst for Segovia’s
production growth in 2018 versus.
Marmato
• Continues to be a steady producer…. evaluating expansion options to incorporate the Deeps mineralization.

• Segovia’s H1‐2018 cash cost improved as production growth lowers fixed costs per ounce and per ounce costs have
