Drill Hole BUUY370D01 Intersects 4.25 metres at 83.65 g/t gold and 29.3 g/t silver
Toronto, Ontario, April 16, 2018 – Continental Gold Inc. (TSX:CNL; OTCQX:CGOOF) (“Continental” or the “Company”) is pleased to announce results from 14 diamond drill holes from its 2018 drilling program at its 100%-owned Buriticá project in Antioquia, Colombia. The Company currently has 12 diamond drill rigs in operation with an additional rig scheduled to start drilling over the next few days. The focus of the program is to increase and upgrade mineral resources to higher classification categories by testing for high-grade and broad mineralized zones within the mineral reserve and resource envelopes. In addition, high-impact targets along strike of existing mineral resources as well as grassroots targets proximal to existing and proposed infrastructure will be tested.
Details (referenced in Figures 1, 2, 3 and 4)
Two horizontal holes were drilled at a true angle to the Yaraguá system. The holes were planned to infill a section of the Murcielagos vein family located a mere 150 metres to the north from the end of the Higabra tunnel. The intercepts are located within the measured and indicated mineral resource envelope and will be sequenced for early mining upon the anticipated production start-up in 2020. Results from both drill holes may have identified potential new shoots of very high-grade gold on two different veins within the Murcielagos family with assay results as follows:
Importantly, these intercepts are running significantly higher than the current mineral resource block model estimate for this area on a grams X metre basis as follows:

As a result, two additional holes have been completed on this section (assays pending) to test for lateral continuity of the high-grade mineralization while a third drill hole is currently underway. Additional holes are planned in the short term to test for extensions to the lateral and vertical continuity of this potential new zone. Assay results for the three additional holes drilled are expected in the near-term and will be reported once compiled and verified.
Twelve shallowly dipping step-out holes were also drilled to the north from the Higabra tunnel at a near true angle to strike of the Yaraguá vein system, intersecting the system at approximately 100 metres below the elevation of the Higabra Tunnel. These holes successfully stepped out past a hard boundary constrained high-grade section of the mineral resource block model for both the Murcielagos and San Antonio vein packages into what has been previously modeled as sub-economic (0.3 – 1 g/t gold) inferred mineral resources. Highlights are as follows:
Ari Sussman, CEO, commented: “Although it’s early to draw too many conclusions based on only two drill holes, we are nonetheless excited about discovering a potential new high-grade shoot given how close it is located to our future plant, both in terms of elevation and distance. In the majority of past precedents at the Buriticá project, similar discoveries of new high-grade areas based on limited drilling have typically developed into shoots with robust lateral and vertical continuity. One of our key objectives going forward is to delineate the potential of this high-grade mineralization as it will possibly add high-grade ounces to our mineral resource inventory. After a sluggish start to drilling in 2018, we are firing on all cylinders and anticipate a steady stream of results on a go forward basis.”

Geological Description of the Buriticá Project
Continental’s 100%-owned, 70,678-hectare project, Buriticá, contains several known areas of high-grade gold and silver mineralization, of base metal carbonate-style (“Stage I”) variably overprinted by texturally and chemically distinctive high-grade (“Stage II”) mineralization. The two most extensively explored of these areas (the Yaraguá and Veta Sur systems) are central to this land package. The Yaraguá system has been drill-outlined along 1,100 metres of strike and 1,700 vertical metres and partially sampled in underground developments. The Veta Sur system has been drill-outlined along 1,000+ metres of strike and 1,800 vertical metres and has been partially sampled in underground developments. Both systems are characterized by multiple, steeply-dipping veins and broader, more disseminated mineralization and both remain open at depth and along strike, at high grades.
Mauricio Castañeda, Vice-President, Exploration of the Company and a qualified person for the purpose of NI 43 101, has prepared or supervised the preparation of, or approved, as applicable, the technical information contained in this press release.

Differences in Reporting of Resource Estimates
This press release was prepared in accordance with Canadian standards, which differ in some respects from United States standards. In particular, and without limiting the generality of the foregoing, the terms “inferred mineral resources,” “indicated mineral resources,” “measured mineral resources” and “mineral resources” that may be used or referenced in this press release are Canadian mining terms as defined in accordance with National Instrument 43 101 – Standards of Disclosure for Mineral Projects under the guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) Standards on Mineral Resources and Mineral Reserves (the “CIM Standards”). The CIM Standards differ significantly from standards in the United States. While the terms “mineral resource,” “measured mineral resources,” “indicated mineral resources,” and “inferred mineral resources” are recognized and required by Canadian regulations, they are not defined terms under standards in the United States. “Inferred mineral resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian securities laws, estimates of inferred mineral resources may not form the basis of feasibility or other economic studies. Readers are cautioned not to assume that all or any part of measured or indicated mineral resources will ever be converted into reserves. Readers are also cautioned not to assume that all or any part of an inferred mineral resource exists, or is economically or legally mineable. Disclosure of “contained ounces” in a resource is permitted disclosure under Canadian regulations; however, United States companies are only permitted to report mineralization that does not constitute “reserves” by standards in the United States as in place tonnage and grade without reference to unit measures. Accordingly, information regarding resources contained or referenced in this press release containing descriptions of our mineral deposits may not be comparable to similar information made public by United States companies.
