Continental Gold Drills 17.20 Metres @ 100.24 g/t Gold Equivalent in BMZ1 at Buriticá

02.04.2019  |  CNW
  • Drilling continues to intercept high-grade gold over broad widths in Broad Mineralized Zone 1 ("BMZ1").
  • DYR0089 intercepted the second highest grade X thickness interval of gold mineralization to date in BMZ1 as follows:
    • 17.20 metres @ 100.24 g/t gold equivalent, including a remarkable sub-interval of 0.60 metres @ 2,851.25 g/t gold equivalent (DYR0089).
  • Multiple additional definition drill-holes into BMZ1 intercepted high-grade gold over excellent thicknesses, with results as follows:
    • 40.75 metres @ 8.03 g/t gold and 10.7 g/t silver (DYR0090)
    • 9.80 metres @ 15.66 g/t gold and 29.9 g/t silver (DYR0092)
    • 10.60 metres @ 20.77 g/t gold and 22.9 g/t silver (DYR0098)
    • 14.00 metres @ 7.07 g/t gold and 3 g/t silver (DYR0093)
    • 30.60 metres @ 5.80 g/t gold and 7.5 g/t silver (DYR0097)
    • 5.84 metres @ 17.17 g/t gold and 22.4 g/t silver (DYR0088)
    • 4.95 metres @ 18.13 g/t gold and 12.2 g/t silver (DYR0105)

Definition drilling for BMZ1 continues to advance according to schedule and additional results will be reported in a timely manner.

  • Two drill holes were completed from a chamber in the central-southern portion of the Yaraguá system. Both holes intercepted thick intervals of gold mineralization south of BMZ1 beginning right at the drill-hole collars, with results as follows:
    • 17.80 metres @ 5.07 g/t gold and 11.1 g/t silver (DYR0068)
    • 21.40 metres @ 3.05 g/t gold and 10.3 g/t silver (DYR0069)

Given that this mineralization is significantly thicker than outlined in the current mineral resource estimate wire frames in this location, extensional drilling will be carried out in the near-term in order to better determine the tonnage potential for this area.

TORONTO, April 2, 2019 - Continental Gold Inc. (TSX:CNL; OTCQX:CGOOF) ("Continental" or the "Company") is pleased to announce additional high-grade assay results from 15 holes drilled into the Yaraguá system as part of the infill and definition 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 primarily targeting the BMZ.

"We continue to make excellent progress at our Buriticá project as we advance towards commercial production in 2020," stated Ari Sussman, CEO. "With eight definition and two exploration drill rigs active on the property, we anticipate making positive progress in defining BMZ's ahead of an updated mine plan prior to the commencement of production, discovering new mineralized areas in the eastern Yaraguá system and confirming production stope locations for mining."

All drill-holes at least partially tested BMZ1, with each hole successfully intercepting high-grade gold mineralization within the zone. The highest-grade drill intercept (grade X thickness) achieved to date in BMZ1 was encountered on the western flank of the zone at a median elevation of 1,464 metres, assaying:

  • 17.20 metres @ 99.95 g/t gold and 21.6 g/t silver, including an ultra high-grade sub-interval of 0.60 metres @ 2,843.77 g/t gold and 560.9 g/t silver (DYR0089).

Outside of the high-grade sub-intercept in drill-hole DYR0089, the hole showed excellent continuity of low-grade mineralization along the length of the drill hole.

Due to short-hole definition drill patterning, seven of the holes only intercepted the southern part of the BMZ1 structure, with additional drilling planned for the northern half of the zone in due course.

Two holes were collared from a drill chamber located approximately 50 metres south of BMZ1 and intercepted thick intervals of moderate grade mineralization in the MU vein package family, with results as follows:

  • 17.80 metres @ 5.07 g/t gold and 11.1 g/t silver (DYR0068)
  • 21.40 metres @ 3.05 g/t gold and 10.3 g/t silver (DYR0069).

Additional drilling is planned in the near term to assess the potential of this area for bulk-style mining with moderate grade material.

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 variably overprinted by texturally and chemically distinctive high-grade 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 drilled 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. 

BMZ Details

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. BMZ1 encompasses a matrix of the east-west trending FW, San Antonio and HW veins as well as a package of a NW?SE vein and subsidiary veinlets.

Technical Information

Mauricio Castañeda, Vice-President, Exploration of the Company and a Qualified Person for the purpose of 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 lab in Medellín run by ALS Colombia Limited ("ALS") in Colombia, 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.

For stope definition core drilling, the Company applied its standard protocols for sampling and assay. The HQ3 samples were full core and provided sample widths between 0.2 to 1.0 metres weighing approximately 2 to 8 kilograms. Custody of the Samples were transferred at the mine site to Actlabs Colombia using rigorous chain-of-custody procedures. Full-core HQ3 samples are prepped and analyzed at Actlabs Colombia's ISO 9001 accredited assay in Medellín, Colombia. The remainder of crushed rejects and pulps are stored in a secured storage facility for future assay verification. Blanks, pulps duplicates, coarse duplicates and purchased certified reference standards are inserted into the sample stream to monitor laboratory performance. A portion of the samples are periodically check-assayed at ALS Peru's ISO 9001 accredited assay laboratory in Lima, Peru.

The Company does not receive assay results for drill holes in sequential order; however, all significant assay results are publicly reported.

Forward-Looking Statements

This press release contains or refers to forward-looking information under Canadian securities legislation—including statements regarding: timing of drill results and first gold pour; advancing the Buriticá project; exploration results; potential mineralization; potential development of mine openings; potential improvement of mining dilution grades; reducing start-up risks; and exploration and mine development plans—and is based on current expectations that involve a number of significant business risks and uncertainties. Forward-looking statements are subject to other factors that could cause actual results to differ materially from expected results. Readers should not place undue reliance on forward-looking statements. Factors that could cause actual results to differ materially from any forward-looking statement include, but are not limited to, an inability to advance the Buriticá project to the next level, failure to convert estimated mineral resources to reserves, capital and operating costs varying significantly from estimates, the preliminary nature of metallurgical test results, delays in obtaining or failures to obtain required governmental, environmental or other project approvals, political risks, uncertainties relating to the availability and costs of financing needed in the future, changes in equity markets, inflation, changes in exchange rates, fluctuations in commodity prices, delays in the development of projects and the other risks involved in the mineral exploration and development industry. Specific reference is made to the most recent Annual Information Form on file with Canadian provincial securities regulatory authorities for a discussion of some of the factors underlying forward-looking statements. All the forward-looking statements made in this press release are qualified by these cautionary statements and are made as of the date hereof. The Company assumes no responsibility to update them or revise them to reflect new events or circumstances other than as required by law.

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.
