Toronto, Ontario, April 15, 2019 — Continental Gold Inc. (TSX:CNL; OTCQX:CGOOF) (“Continental” or the “Company”) is pleased to announce high-grade channel sampling assay results from three development drifts where up to five stope areas are being prepared for production as part of the underground construction at its 100%-owned Buriticá project in Antioquia, Colombia. Development of the Buriticá project remains on schedule with first gold pour anticipated in H1 2020. Supporting information for results discussed in this release can be found in Figures 1-3 and all sampling widths reported herein are at horizontal metres.
“Underground development continues to successfully block out areas for mining at the upper elevations of the deposit. Our stope development drifts continue to demonstrate excellent lateral continuity of high-grade gold over significant strike lengths,” stated Ari Sussman, CEO. “Underground drifting at the lower elevation where the processing plant is being constructed has finally advanced to the point that we are now starting to develop along modelled high-grade gold domains. We are excited to be opening up the mineralized system at this lower elevation with underground development and are optimistic that we will continue to see robust high-grades of gold along the new development drifts in the coming weeks.”
Assay results have been received for channel sampling results of three stope development drifts totalling 174 metres strike length. Two of the development drifts are located in the Yaraguá system and the other drift is located in the Veta Sur system. Stopes are being designed within the development drifts to measure between 25 and 45 metres in length using an 18-metre sublevel spacing.
Stope areas 1 and 2 are located on the SA vein domain along the same drift in the central part of the Yaraguá system at an elevation of 1,444 metres. Stope area 1, which is located on the western portion of the development drift, has demonstrated excellent continuity with assay results as follows:
Stope area 2 is located on the eastern portion of the same development drift with high-grade assay results as follows:
Development for this drift in the Yaraguá system has been extended further west in order to lengthen the strike of stope area 2 and results are anticipated in the near term.
Stope area 3 is located along the Centena vein in the northern portion of the Yaraguá system at an elevation of 1,487 metres, with high-grade assay results as follows:
Stope areas 4 and 5 are located along the same development drift located in the central portion of the Veta Sur system at an elevation of 1,578 metres and have yielded high-grades of both gold and silver over a significant strike length as follows:
Additional stope drifts at various elevations are currently being developed for both the Yaraguá and Veta Sur systems; once channel sampling assay results are received and evaluated, they will be released in a timely manner.
Channel sample results are reported without consideration of modifying factors such as dilution, which are included in the mineral reserve estimate.
For reference, the mineral reserve estimate for the Buriticá project (as at May 11, 2015), derived from the 2015 Mineral Resource Estimate, is as follows:
Notes: Based on cut-off grades of 3.8 g/t for Yaraguá and 4.0 g/t for Veta Sur, $950 per ounce gold price, and US$:COP exchange rate of 2,850. Rounding of some figures may lead to minor discrepancies in totals.

Geological Description of the Buriticá Project
Continental’s 100%-owned, 75,583-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.
Donald Gray, Chief Operating Officer 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 release.
Channel samples are taken continuously along the walls of the underground cross-cut and across the face of the underground drift. Faces are nominally spaced every 3 metres along the drift, and face composites average six length-weighted channel samples. Widths are horizontal metres at 0 g/t gold cut-off grade and no capping has been applied to sample composites. The Company utilizes a rigorous, industry-standard QA/QC program.
Rock samples have been prepared and analyzed at Continental Gold’s Yaraguá mine laboratory at Buriticá, Colombia. Blanks, duplicates and certified reference standards are inserted into the sample stream to monitor laboratory performance. 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 not independent or certified under NI 43 101 and, as such, results in this release should only be taken by the reader as indicative of future potential.
Gold equivalent numbers used in this release were calculated at a 75:1 silver to gold ratio at an assumed metallurgical recovery rate of 100%.
