Toronto, Ontario, November 12, 2018 — Continental Gold Inc. (TSX:CNL; OTCQX:CGOOF) (“Continental” or the “Company”) is pleased to announce additional high-grade assay results from the initial 18 definition holes and five infill holes drilled into the Veta Sur system as part of its 2018 definition and exploration drilling program at its 100%-owned Buriticá project in Antioquia, Colombia. The Company presently has 13 diamond drill rigs in operation; three rigs are being utilized for the ongoing stope definition drilling program, eight rigs are conducting infill and mineral resource expansion drilling at the Yaraguá and Veta Sur deposits and two rigs are testing the Laurel and Perseus greenfield targets.

Ari Sussman, CEO commented: “Our team is most pleased with the drill results announced herein as they are helping to verify the upper boundary of the mineral reserve envelope for the Veta Sur system. In addition to the continuity and mineability of Veta Sur being confirmed with these infill and definition drill holes, the broad intercepts encountered are extremely encouraging and may provide more mining flexibility than anticipated.”

Detail Summary (see Table 1 and Figures 1, 2, 3 and 4)

A total of 23 diamond drill holes were completed in the Veta Sur system, including the initial 18 definition drill holes completed to date. Definition holes DVS0001-DVS0007 were drilled to the northwest from a chamber located along the main access ramp in the southwestern portion of the Veta Sur system. Results to date are being used to verify and finalize stope designs and schedule production from this area, anticipated in 2020. Definition drilling on this section is continuing at present, albeit from a different chamber and at a new orientation.

Definition holes DVS0009-DVS0018 were drilled from a chamber located in the central part of the Veta Sur system. Results from high-grade intercepts in this area are also being used to verify and finalize stope designs for production anticipated in 2020. Key results include:

  • 1.65 metres @ 51.61 g/t gold and 65.2 g/t silver (DVS0016, Vein 65, 1653RL)
  • 3.48 metres @ 36.01 g/t gold and 194.9 g/t silver (DVS0017, Vein 51, 1623RL)
  • 1.35 metres @ 27.26 g/t gold and 28.5 g/t silver (DVS0011, Vein 65, 1639RL)

A total of five infill drill holes were completed from a single chamber located along the Veta Sur ramp and targeted two different sections of the Vein 65 master family. Broad intercepts were encountered in three holes with high-grade gold in narrow veins scattered throughout all of the holes, with key results as follows:

  • 31.95 metres @ 4.14 g/t gold and 219.1 g/t silver (BUUY398, Veins 70, 65, 62, 51, 48 and 43; 1492RL)
  • 14.40 metres @ 8.62 g/t gold and 25 g/t silver (BUUY392, Veins 48, 43, 42 and 41; 1507RL)

Geological Description of the Buriticá Project
Continental’s 100%-owned, 75,023-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 1,350 metres of strike and 1,800 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.

BMZ Details
The broad mineralized zone (“BMZ”) consists of a group of modelled precious metal-bearing veins in the current mineral resource estimate block model with 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 identified up to seven BMZ targets for testing and will systematically drill each target zone as underground mine development advances.

Technical Information
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.

Reported intervals include minimum weighted averages of 3 g/t gold equivalent (70:1 Au/Ag) over core lengths of at least 1.0 metres. Assays are uncut except where indicated.

Besides rigorous chain-of-custody procedures, the Company utilized a comprehensive quality control/quality assurance program for the channel samples. All quality control anomalies were addressed and/or corrected as necessary to assure reliable assay results; no material quality control issues were encountered in the course of the program. Crush rejects and pulps are kept and stored in a secured storage facility for future assay verification. Although historic correlation between analytical results from the Company’s internal laboratory and certified independent laboratories for gold and silver analysis have been within acceptable limits, the Company’s internal laboratory is neither independent nor certified under NI 43-101 guidelines and, as such, channel sampling results in this release should only be taken by the reader as indicative of future potential.

For exploration and infill core drilling, the Company applied its standard protocols for sampling and assay. 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.

For stope definition core drilling, the Company applied its standard protocols for sampling and assay. The HQ3 samples were full core and provided sample widths between 0.2 to 1.0 in metres weighing approximately 2 to 8 kilograms. Custody of the Samples were transferred at the mine site to Actlabs Colombia using rigorous chain-of-custody procedures. Full-core HQ3 samples are prepped and analyzed at Actlabs Colombia’s ISO 9001 accredited assay in Medellín, Colombia. The remainder of crushed rejects and pulps are stored in a secured storage facility for future assay verification. Blanks, pulps duplicates, coarse duplicates and purchased certified reference standards are inserted into the sample stream to monitor laboratory performance. A portion of the samples are periodically check-assayed at ALS Peru’s ISO 9001 accredited assay laboratory in Lima, Peru.

The Company does not receive assay results for drill holes in sequential order; however, all significant assay results are publicly reported.

Forward-Looking Statements
This press release contains or refers to forward-looking information under Canadian securities legislation—including statements regarding: timing of drill results, an updated mineral resource estimate and mine plan and commercial production; advancing the Buriticá project; exploration results; potential mineralization; potential development of mine openings; potential improvement of mining dilution grades; reducing start-up risks; and exploration and mine development plans—and is based on current expectations that involve a number of significant business risks and uncertainties. Forward-looking statements are subject to other factors that could cause actual results to differ materially from expected results. Readers should not place undue reliance on forward-looking statements. Factors that could cause actual results to differ materially from any forward-looking statement include, but are not limited to, an inability to advance the Buriticá project to the next level, failure to convert estimated mineral resources to reserves, capital and operating costs varying significantly from estimates, the preliminary nature of metallurgical test results, delays in obtaining or failures to obtain required governmental, environmental or other project approvals, political risks, uncertainties relating to the availability and costs of financing needed in the future, changes in equity markets, inflation, changes in exchange rates, fluctuations in commodity prices, delays in the development of projects and the other risks involved in the mineral exploration and development industry. Specific reference is made to the most recent Annual Information Form on file with Canadian provincial securities regulatory authorities for a discussion of some of the factors underlying forward-looking statements. All the forward-looking statements made in this press release are qualified by these cautionary statements and are made as of the date hereof. The Company assumes no responsibility to update them or revise them to reflect new events or circumstances other than as required by law.

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.
