Toronto, Ontario, March 1, 2019 – Continental Gold Inc. (TSX:CNL; OTCQX:CGOOF) (“Continental” or the “Company”) is pleased to announce additional high-grade assay results from 10 holes drilled into the Yaraguá system as part of the exploration drilling program at its 100%-owned Buriticá project in Antioquia, Colombia. The Company plans to drill up to 73,500 metres in 2019, consisting of approximately 55,000 metres of capitalized definition drilling and approximately 18,500 metres of exploration-led infill drilling. Supporting information for results discussed in this release can be found in Table 1 and Figures 1 and 2.
“With only 15 drill holes completed to date into our newly-discovered BMZ2, we are off to an exciting start in outlining this new zone. Due to BMZ2 demonstrating excellent continuity and high grades over robust thicknesses, the Company has prioritized both exploration and definition drilling for the zone on the belief that BMZ2 will ultimately be integrated into the early years of mining for the Project,” stated Ari Sussman, CEO.
Ten diamond drill holes were completed in the eastern area of the Yaraguá system, of which seven drill holes targeted BMZ2. Unfortunately, two holes (BUSY394 and BUSY396) were completed prior to receiving assay results leading to the January 15, 2019 announcement of the discovery of BMZ2 and consequently were drilled too far north to intercept the zone. The five holes that intercepted BMZ2 all successfully encountered high-grade gold over robust thicknesses and extended the dimensions of the zone to 100 metres along strike by 225 metres vertically. BMZ2 remains open along strike to the east and at depth for future expansion. Two diamond drill rigs are now turning and assay results will be reported in due course.
Two diamond drill holes (BUSY385D03 and BUSY385D04) tested a section of the current mineral resource model approximately 200 metres below the elevation of the Higabra Tunnel which intersected gold mineralization, including a best intersection of 6.10 metres @ 7.78 g/t gold and 5.8 g/t silver (BUSY385D04).
Additionally, one diamond drill hole (BUSY403) deviated from its planned location approximately 75 metres east of BMZ2 and potentially discovered a new BMZ zone. Results include two broad lower-grade intervals and one high-grade interval of 9.25 metres @ 7.62 g/t gold equivalent.
Assay results for all drill-holes reported in this release are reported in the table below:
* Intercepts calculated for minimum intervals of 0.5 metres.
** Grades herein are reported as uncapped values. Gold equivalent in this release and table was calculated at Au:Ag ratio of 75:1 with no assumptions made for metallurgical recovery rates.
*** True widths intercepted modelled veins outside of the BMZs are estimated to be between 75-100%. In the BMZs, however, the zone consists of veins at various orientations so individual drill holes will intercept certain veins within the zone at up to true orthogonal angles and others at up to oblique angles.

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 1,300+ 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.
The 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.
BMZ2 is a three-dimensional orebody interpretation and modelling with variability in width, thickness along a vertical extension. Additional core drilling is been planned to define its characteristics, such as gold/silver grades, geometry and vertical extension.
Mauricio Castañeda, Vice-President, Exploration of the Company and a Qualified Person for the purpose of Canadian National Instrument 43 101 (“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 (1:75 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 laboratory in Medellín run by ALS Colombia Limited (“ALS”), 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 necessarily receive assay results for drill holes in sequential order; however, all significant assay results are publicly reported.

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.
