Deepest Drill Hole Intersects 45.6 metres at 17.67 g/t gold and 16 g/t silver
TORONTO, ON – (Marketwired – September 18, 2017) – Continental Gold Inc. (TSX: CNL)(OTCQX: CGOOF)(“Continental” or the “Company”) is pleased to announce the first results from its 2017 exploration drilling program at its 100%-owned Buriticá project in Antioquia, Colombia. As a result of the early encouraging results, the Company is increasing its drill program for calendar 2017 from 15,000 to 25,000 metres and will increase from three to eight drill rigs by early November 2017. The focus of the program is to both increase and upgrade mineral resources to higher classification categories by testing for high-grade and broad mineralized zones within both the mineral reserve and mineral resource envelopes as well as high-impact targets along strike of existing mineral resources and grassroots targets proximal to existing and proposed infrastructure.
Highlights (referenced in Figures 2, 3 and 4)
Broad Mineralized Zone (“BMZ”)
The BMZ consists of a group of modelled precious metal-bearing veins in the mineral resource estimate with significant mineralization occurring between these veins, generally in the form of veinlets at oblique angles to strike. The majority of the mineralization between modelled veins is not in the current mineral resource estimate, providing potential upside both in terms of identifying significantly broader and more productive zones for mining and increased mineral resources. To date, the Company has modelled six BMZ targets for testing, each of which has potential to be 500 metres or more in vertical length.
The first BMZ target in the Yaraguá deposit (Figure 1, See target #1), discovered in 2016 through a series of true horizontal width cross-cuts covering 20 vertical metres, has been extended an additional 80 vertical metres (100 metres total) by drilling. The BMZ averages approximately 30 metres true horizontal width and 30 metres lateral strike and remains wide open at depth along strike to both the east and west and down-plunge. A composite weighted average of all drill holes intersecting the BMZ is as follows:
Two drill holes, which extended the vertical dimension of the BMZ to 100 metres by encountering the deepest BMZ mineralization to date at an elevation of 1,465 RL, intersected robust gold grades and widths as follows:
The Company plans to construct a new drilling chamber in the near future at a lower level to target the continuation of this BMZ to deeper elevations upon further advancement of commercial underground development at the Yaraguá deposit.
BUUY333 was drilled outside the BMZ to the east, defining the eastern limit of this zone at an elevation of approximately 1,500 RL. However, the drill hole successfully infilled the Yaraguá vein system, intersecting grades X thickness in line with the mineral resource block model as follows:
Three drill rigs continue to operate with numerous holes completed and awaiting assays. Results are expected to continue to be released in a timely manner.
Ari Sussman, Chief Executive Officer, stated: “The results of BMZ drilling are impressive to say the least and will lead to greater mine plan flexibility once commercial production commences in 2020. The potential is very real for upside growth in total mineral resource ounces and improved project economics. Our geological team’s ability to generate exciting brownfield and grassroots targets from our rich mineral district at Buriticá will continue to be a value-driver for shareholders as blue-sky potential is unlocked. Accelerating the drilling program only makes sense given the upside, the support of Newmont Mining and the strong financial position of the Company.”
Table I: Drill Holes Targeting the BMZ
* Intercepts calculated at a composite 1 g/t gold equivalent (70:1 Au/Ag) for minimum intervals of 0.5 metres, with up to 20% internal dilution. Drill holes designated “BUUY” were collared from underground.
** Grades herein are reported as uncapped values.
Note: Certain drill holes went through narrow mined-out tunnels and, for those intersections, precious metal grades from either the May 2015 NP 43-101 mineral resource block model or channel sampling results previously announced were incorporated into the overall interval. If neither were available, a grade of nil was assigned.

Geological Description of the Buriticá Project
Continental’s 100%-owned, 70,764-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.
The Company utilizes a rigorous, industry-standard QA/QC program. HQ and NQ core is sawn or split with one-half shipped to a sample preparation lab in Medellín run by ALS Colombia Limited (“ALS”) in Colombia, whereas BQ core samples are full core. Samples are then shipped for analysis to an ALS-certified assay laboratory in Lima, Peru. The remainder of the core is stored in a secured storage facility for future assay verification. Blanks, duplicates and certified reference standards are inserted into the sample stream to monitor laboratory performance and a portion of the samples are periodically check assayed at SGS Colombia S.A., a certified assay laboratory in Medellín, Colombia.
The Company does not receive assay results for drill holes in sequential order; however, all significant assay results are publicly reported. A listing of assay results to date for the Buriticá project is available on the Company’s website at www.continentalgold.com.

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.
