| ABSTRACT: | This report was prepared as a Mineral Resource update Canadian National Instrument 43-101 (NI 43- 101) Technical Report (Technical Report) for Gran Colombia Gold Corp. (GCM, Issuer, or Company) by SRK Consulting (U.S.), Inc. (SRK) on the Marmato Gold Project (Marmato or Project). This Technical Report provides an update on the Mineral Resource at Marmato. In the current gold market, GCM feels it is prudent to change their approach for the Marmato Project, shifting from a largescale, low-grade open pit operation as previously conceived, to a smaller-scale, higher-grade underground mining operation. The Project currently has a number of small-scale and one commercialscale operating mine using underground mining methods. This Technical Report describes the current mining and processing methods, but the reader is cautioned that this report should not be considered a preliminary economic assessment (PEA), for the Project, and the previous study, as it considered open pit mining, is not relevant to the proposed changes. SRK has recommended that GCM commence work on preparing a PEA for the underground option, which has commenced, but will require further investigation and is estimated for completion in 2018. The current options will continue during this time period and are therefore summarized in this Technical Report. | |
