Continental Gold Drills Visible Gold in All Holes Targeting the Centena Vein at Buriticá

Drill Hole BUUY434 Intersects 0.50 metres at 582 g/t gold and 159 g/t silver

Toronto, Ontario, June 24, 2019 – Continental Gold Inc. (TSX:CNL; OTCQX:CGOOF) (“Continental” or the “Company”) is pleased to announce assay results for four diamond drill holes at its 100% owned Buriticá project in Antioquia, Colombia. Assay results reported herein are for the initial exploration holes drilled into the northeastern portion of the Yaraguá system targeting the Centena vein family.

The Company currently has 11 diamond drill rigs operating as part of its 73,500-metre definition and exploration drill program for 2019. Construction of the Buriticá project was 67% complete as of May 31, 2019 and remains on schedule for first gold pour in H1 2020.

Highlights (Referenced in Figures 1 and 2 and Image 1)

  • Four underground diamond drill holes were completed into the northeastern portion of the Yaraguá vein system as part of a systematic program targeting the Centena vein with the objective of converting Inferred mineral resources to the Indicated category and adding new ounces by stepping out along extensions to the northwest. Centena is a northwest-to-southeast high-grade master vein with a continuous strike of more than 800 metres and vertical extension drilled for more than 1,000 metres.
  • High-grade visible gold (see Image 1) was encountered in all four holes covering a block measuring 50 x 50 metres on the Centena vein with results as follows:
    • 1.20 metres @ 44.90 g/t gold and 50.4 g/t silver (BUUY433)
    • 0.50 metres @ 582.00 g/t gold and 159.0 g/t silver (BUUY434)
    • 0.50 metres @ 47.20 g/t gold and 363 g/t silver (BUUY435)
    • 2.10 metres @ 35.54 g/t gold and 47.9 g/t silver (BUUY435)
    • 1.05 metres @ 44.41 g/t gold and 273.1 g/t silver (BUSY436, Centena vein splay)
  • Importantly, these intercepts are grading significantly higher than the current Inferred mineral resource block model estimate for this area of the Centena vein on a gram x metre (true width) basis. Individual results measured against the block model compare as follows:

  • The high-grade mineralization remains open along strike and down dip. Six new drill holes are currently progressing to test the Centena vein with additional drill holes planned. Assay results will be reported in due course.
  • This portion of the Centena vein is located approximately 100 metres below current underground mine development and plans are being implemented to drive towards this zone in the near term to enable further definition drilling and incorporation of this area into the earlier years of the new mine plan.

“Our strategy of drill-testing targets that have potential for being incorporated into the first three years of mine life at Buriticá has yielded excellent results in 2019. With the recent discovery of BMZ4 and assay results from drilling of the Centena Vein yielding, on a weighted average basis, greater than a 500% higher grade of gold than the mineral resource block model in the corresponding locations, we have plenty to look forward to in the coming months,” commented Ari Sussman, CEO.

Details and Assay Table

Centena is a northwest-to-southeast high-grade master vein with a continuous strike of more than 800 metres, which crosses the majority of the east-west trending Yaraguá master vein system. The intersection of the Centena vein with the Yaraguá vein system typically results in zones of higher-grade gold and silver over wider intervals. Broad mineralized zones (BMZ) are typically developed at the intersection of the NW (Centena and NW veins) and EW (Yaraguá) vein systems. Due to difficult topography limiting the Company’s ability to drill the northern portion of the Yaraguá system, significant potential exists for discovery of new east-west trending veins along the intersection with the Centena vein. With underground development rapidly advancing, new areas are being installed for further drilling to the north and the potential exists for new mineralization to be incorporated into the early years of a revised mine plan for the Yaraguá system.

Geological Description of the Buriticá Project
Continental’s 100%-owned, 75,604-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.

Differences in Reporting of Resource Estimates
This press release was prepared in accordance with Canadian standards for reporting of mineral resource estimates, which differ in some respects from U.S. 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” used or referenced in this release are Canadian mineral disclosure terms as defined in accordance with NI 43-101 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”). Until recently, the CIM Standards differed significantly from standards in the U.S. The U.S. Securities and Exchange Commission (the “SEC”) has adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”). These amendments became effective February 25, 2019 (the “SEC Modernization Rules”) with compliance required for the first fiscal year beginning on or after January 1, 2021. The SEC Modernization Rules replace the historical property disclosure requirements for mining registrants that were included in SEC Industry Guide 7, which will be rescinded from and after the required compliance date of the SEC Modernization Rules. As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources”. In addition, the SEC has amended its definitions of “proven mineral reserves” and “probable mineral reserves” to be “substantially similar” to the corresponding definitions under the CIM Standards, as required under NI 43-101. Accordingly, during this period leading up to the compliance date of the SEC Modernization Rules, information regarding mineral resources or mineral reserves contained or referenced in this release may not be comparable to similar information made public by United States companies. Readers are cautioned that “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 rules, estimates of inferred mineral resources may not form the basis of feasibility or other economic studies, except in limited circumstances. The term “resource” does not equate to the term “reserves”. Readers should not assume that all or any part of measured or indicated mineral resources will ever be converted into mineral 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.
