Gran Colombia Gold reported its Q1-2017 results. Gold production was 39,008 ounces, up 26% from Q1-2016, driven by strong performance from contract miners at its Segovia Operations in Colombia. Cash costs were $748/ounce and AISC was $941/ounce. The company generated $2.3 million in excess cash flow in the quarter and is on track to meet its 2017 production guidance of 150,000-160,000 ounces. Gran Colombia also updated resources at Segovia, with measured and indicated resources increasing to 1.1 million ounces from 402 thousand ounces in December 2016.

Q1‐2017 total cash cost for the Company of $748/oz in line with Company expectations for the current quarter. 2017 full
year average expected to remain below $720/oz.
• Q1‐2017 total cash cost adversely impacted by 10% appreciation of COP relative to USD over the last year. Increased
the Company total cash cost by $40/oz versus Q1‐2016 ($29/oz at Segovia, $100/oz at Marmato).
• Marmato total cash cost per ounce in Q1‐2017 also reflects adverse impact on gold production of the lower head
grades versus Q1‐2016.
