Canadian-listed (TSX: GCM) producer with offices in Toronto and Medellin.

Primary focus is on the high-grade Segovia Operations. Continuing to expand and mechanize the underground miningoperations (~86% of total LTM production). Recently announced a 4-year extension in mine life to 2026.

The Marmato Project, one of the Top-20 largest undeveloped global gold deposits, provides significant optionality to gold andsilver prices. Currently evaluating the potential to expand the existing underground mining operations, incorporating additionalresources from the deep mineralization.

The Zancudo Project, a former high-grade producer, provides exploration upside. IAMGOLD signed an option agreement in2017 to conduct exploration and for the potential purchase of an interest.

Reducing Senior Secured Debt and potential dilution ahead of maturity with Excess Cash Flow.

LTM gold production of 165,073 ounces, up 10% over 2016 annual production.

LTM AISC averaged US$901/oz…..expected to be below US$900/ozfor the full year 2017.

Upside in resource expansion and exploration assets in Colombia.

Leading Colombian high-grade underground gold producer. undervalued versus peers!

2016 ACCOMPLISHMENTS

Priorities Completed senior debt restructuring in January 2016. Made all monthly interest payments on Senior Debentures. Continued implementation of optimized mine plan at Segovia. Completed 10,000m drilling program at Segovia….upgraded resources. Improved balance sheet by reducing working capital deficit. Balance sheet improved through conversion of Senior Debentures to equity. Generated Excess Cash Flow for deposit to sinking funds for Senior 

Debentures and used funds to repurchase debt for cancellation.2016 Targets
