Continental Gold Drills High-Grade Gold Over 1,200 Vertical Metres at Veta Sur and Confirms the Laurel System as a Major Discovery at Buriticá, Colombia
Drilling intersects a new vein at depth yielding 3.75 metres @ 51.39 g/t gold and 35 g/t silver
TORONTO, May 02, 2018 (GLOBE NEWSWIRE) — Continental Gold Inc. (TSX:CNL) (OTCQX:CGOOF) (“Continental” or the “Company”) is pleased to announce results from the initial seven diamond drill holes into the Veta Sur system and the Laurel target as part of its 2018 drilling program at its 100%-owned Buriticá project in Antioquia, Colombia. The Company currently has 14 diamond drill rigs in operation, working to increase and upgrade mineral resources to higher classification categories by testing for high-grade and broad mineralized zones within the mineral reserve and resource envelopes. In addition, high-impact targets along strike and below existing mineral resources, as well as grassroots targets proximal to existing and proposed infrastructure, are now being tested.
“Without question, the results today confirm that the Veta Sur system, like the Yaraguá system to the immediate east, is world-class in size as we have not yet been able to define the limits of the sheeted veins system. Veta Sur, which has already been drilled over 1,100 metres of strike by 1,700 vertically, continues to expand with the discovery of new veins in the footwall northwest of the system at depth,” commented Ari Sussman, CEO. “Additionally, the Laurel system can now be confirmed as an important discovery, measured over 1,250 metres along strike by 1,250 metres vertically. A considerable amount of drilling will still need to take place at Laurel to prove up a mineral resource; however, with the discovery of high-grade visible gold in the system for the first time, we are prioritizing drilling to attack it aggressively.”
Laurel Target (referenced in Figures 1, 2 and 5)
Scout drilling of the greenfield Laurel target (“Laurel”) has confirmed that the potential exists for it to evolve into a third major high-grade vein system. Laurel is fortuitously located directly south of the Veta Sur system and a short distance south from the planned location of the Veta Sur ramp, which is currently under construction. The Laurel target has been sparsely traced by drilling and sampling over large dimensions measuring 1,285 metres along strike by 1,250 metres vertically and remains open in all directions for expansion.
High-grade results from drilling include:
- 1.65 metres @ 14.05 g/t gold and 11.4 g/t silver (BUSY374D03)
- 0.50 metres @ 59.20 g/t gold and 86.1 g/t silver (BUSY374D03)
- 1.55 metres @ 15.56 g/t gold and 15.9 g/t silver (BUSY374D03)
Given the close proximity of the Laurel target to the Veta Sur ramp currently under construction, the Company is prioritizing it for drilling as good potential exists for Laurel to be incorporated into the early years of the mine plan. A second diamond drill rig has arrived at site and is being set up to test for western extensions of the Laurel system over a myriad of vertical elevations with additional drilling currently in the planning phase.
Veta Sur System (referenced in Figures 1, 2, 3 and 4)
Seven diamond drill holes intersected the Veta Sur system (“Veta Sur”) at various elevations covering more than 1,100 vertical metres and once again proving that the system hosts excellent continuity of high-grade gold over large dimensions. Importantly, the system demonstrates clear metal zonation as depicted by the mineralogy with high-grades of gold and silver associated with zinc, lead and pyrite at shallow elevations, giving way at deeper elevations to gold, pyrrhotite and slightly elevated copper. This type of metal zonation suggests that the system is more proximal to a porphyry source at depth and deep drilling is planned to try and find a porphyry system.
The first directionally drilled step-out hole in over three years into Veta Sur (BUUY349D02) successfully extended high-grade gold 300 metres below the deepest part of the inferred resource estimate above cut-off grade in the central portion of Veta Sur. Additionally, the same hole also stepped out at depth along strike and discovered multiple new high-grade veins with key highlights as follows:
- 3.10 metres @ 38.38 g/t gold and 57.3 g/t silver (BUUY349D02, elevation 635 metres above sea level (“ASL”); 200 metre extension below the lowest limit of the inferred mineral resource envelope above cut-off grade)
- 3.75 metres @ 51.39 g/t gold and 35 g/t silver (BUUY349D02, a new vein 20 metres to the northwest of the most northwesterly vein modeled at Veta Sur at an elevation of 501 metres ASL; 300 metres below the lowest limit of the inferred mineral resource envelope)
Drill holes BUSY374D01-03, intersected high-grade gold in the Veta Sur system within the inferred mineral resource envelope at elevations between 930-980 metres ASL as follows:
- 4.25 metres @ 28.35 g/t gold and 62.8 g/t silver (BUSY374D01)
- 10.05 metres @ 6.53 g/t gold and 37.3 g/t silver (BUSY374D02)
- 4.00 metres @ 22.44 g/t gold and 134.6 g/t silver (BUSY374D03)
Grades encountered in these three drill holes are generally much higher than the current inferred mineral resource estimate for this area of the block model with results as follows:

In the past, drill testing the depth potential of Veta Sur was limited due to lack of access. With underground development advancing at a productive rate and providing suitable drilling locations, the Company will be aggressive in looking to grow the mineral resources at Veta Sur over the balance of the year.
Infill drilling at much higher elevations from Veta Sur intersected grades that were generally in line with the mineral resource block model with significant results as follows:
- 3.30 metres @ 9.48 g/t gold and 104.9 g/t silver (BUUY368)
- 0.50 metres @ 100.5 g/t gold and 195 g/t silver (BUUY373)

Geological Description of the Buriticá Project
Continental’s 100%-owned, 70,678-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 1,100 metres of strike and 1,700 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.

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.
