Continental Gold Announces High-Grade Gold Channel Sampling Results from Underground Development Drifts at Buriticá, including 14.18 g/t Gold along 38 Metres of Strike
TORONTO, Oct. 9, 2019 /CNW/ - Continental Gold Inc. (TSX:CNL; OTCQX:CGOOF) ("Continental" or the "Company") is pleased to announce high-grade channel sampling assay results from six development drifts being prepared as part of the underground construction at its 100%-owned Buriticá project in Antioquia, Colombia. Development of the Buriticá project remains on schedule with mechanical completion anticipated in Q1 2020. Supporting information for results discussed in this release can be found in Figures 1-4 and all sampling widths reported herein are horizontal metres.

New channel sampling results from underground development drifts being evaluated for stope design in the Yaraguá system have returned high grades of gold and silver over significant strike lengths. Results are as follows:
38 metres @ 14.18 g/t gold and 32.22 g/t silver at 3.6 metres width
24 metres @ 15.6 g/t gold and 21.4 g/t silver at 2.5 metres width
58 metres @ 8.13 g/t gold and 13.45 g/t silver at 2.66 metres width
41 metres @ 12.2 g/t gold and 44.3 g/t silver at 2.4 metres width
80 metres @ 9.73 g/t gold and 41.3 g/t silver at 2.6 metres width
22 metres @ 11.1 g/t gold and 11.2 g/t silver at 2.6 metres width
The weighted average gold grade for these mineralized intervals is 11.17 g/t gold over 263 metres strike length.
Development drifts continue to be well-mineralized along the entire strike length where channel sampling results have been reported.
Face channel sampling in the drifts includes gold mineralization that extends beyond the width of the development drift, indicating potential for broader mineralization than currently reported. Short distance bazooka drilling is underway to assess this potential.
40 stopes are currently in various stages of preparation for production in 2020.
"The project continues to advance on schedule with mechanical completion expected in Q1 2020. We continue to be pleased with the continuity of the high-grade gold being encountered over significant distances," commented Ari Sussman, CEO. "With the new ventilation raise now complete, air flow has drastically improved in the lower portion of the mine, resulting in a marked increase in the pace of development. With a new crosscut advancing to the north at the Higabra valley elevation through the Yaraguá system, we are seeing new mineralized structures that fall outside of the current mineral resource model. More importantly, we have begun drifting on these new structures and are encountering strong visual mineralization. We are excited for further advancement of these drifts to see what else we encounter and for the corresponding assay results to be received in due course."
Details
Assay results have been received for channel sampling from six development drifts totalling 263 metres of strike length. All of the development drifts are located in either the upper or lower portions of the Yaraguá system.
Figure 1
Located in the eastern portion of the Yaraguá system on Sublevel 1465, high-grade gold has been encountered along a mineralized corridor being developed eastward from the crosscut, with results as follows:
38 metres @ 14.18 g/t gold and 32.22 g/t silver at 3.6 metres width
Figure 2
Two drifts—located further to the south and approximately 60 metres lower in elevation on Sublevel 1405—have encountered high-grade gold over significant strike lengths along the same mineralized corridor, with results as follows:
80 metres @ 9.73 g/t gold and 41.3 g/t silver at 2.6 metres width; and
41 metres @ 12.2 g/t gold and 44.3 g/t silver at 2.4 metres width
Figure 3
Located some 215 metres deeper on Sublevel 1190 near the elevation of the Higabra valley (where the project infrastructure is being constructed), high-grade gold has been encountered in recent drift development along two separate mineralized structures. Situated in the southwestern portion of the Yaraguá system, high grades of gold have been encountered on the western portion of the southern drift and the eastern portion of the northern drift, with results as follows:
24 metres @ 15.6 g/t gold and 21.4 g/t silver at 2.5 metres width; and
22 metres @ 11.1 g/t gold and 11.2 g/t silver at 2.6 metres width
Development of the northern drift continues to advance in mineralization to the east.
Figure 4
Located slightly further to the east at an elevation that is 15 metres deeper on Sublevel 1175, high-grade gold has been encountered over a significant strike length, with results as follows:
58 metres @ 8.13 g/t gold and 13.45 g/t silver at 2.66 metres width
Other
Additional development drifts at various elevations are currently being advanced for both the Yaraguá and Veta Sur systems. In particular, with suitable ventilation now being distributed at the Higabra valley elevation, development has accelerated and multiple new drifts have been initiated on strongly-mineralized veins. More results will be forthcoming as these new drifts are advanced and channel sampling assay results are received and evaluated.

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.
Technical Information
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 crosscut and across the face of the underground drift. Faces are nominally spaced every 2 to 3 metres along the drift, and face composites average six length-weighted channel samples. Averaged mineralized widths shown in the tabulations and figures for selected intervals along strike are horizontal metres at a 2.0 g/t Au cut-off and a 2.4-metre minimum width. Face sample composites are length-weighted for each face sample. The drift grade averages incorporate weighting by the strike influence of each face determined from the actual face spacing. The minimum width is chosen to match the expected stope minimum width; thus, the intervals include some of expected planned edge and internal mining dilution. 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.
