Continental Gold Drills Broad and High-Grade Intervals in Infill and Extensions of the Yaragua System at Buritica, Colombia

 


 

TORONTO, ONTARIO–(Marketwired – April 29, 2015) –Continental Gold Limited (TSX:CNL)(OTCQX:CGOOF) (“Continental” or the “Company”) is pleased to announce results for 17 diamond drill-holes through the Yaraguá vein system at the Company’s 100%-owned Buriticá project in Antioquia, Colombia. Drilling continues with the goal of upgrading Inferred resources into the Measured and Indicated categories under National Instrument 43-101 (“NI 43-101”) guidelines, and delivering overall mineral resource growth. An updated mineral resource estimate for the Buriticá project remains on track for completion in late Q2 2015.

Highlights (referenced in Figures 1, 2, 3 and 4)

– Step-out drilling was successful in extending the Yaraguá system to the west and to depth whereas infill drilling, largely at high angles to the veins, focused on elevations around the Higabra tunnel.

– In western Yaraguá, step-out drilling extended a bulk mineralized zone discovered in BUSY291 (65.1 metres @ 10.4 g/t gold and 9 g/t silver, CNL News Release, November 12, 2012). New intercepts in this zone, located below the current Yaraguá mineral resource envelope, include:

  • 17.38 metres @ 10.8 g/t gold and 7 g/t silver (BUUY291D01, elevation of 614 metres);
  • 10.3 metres @ 6.2 g/t gold and 5 g/t silver (BUUY291D02, elevation of 640 metres);
  • 7.95 metres @ 4.7 g/t gold and 6 g/t silver (BUUY291D03, elevation of 537 metres); and
  • 21.15 metres @ 4.6 g/t gold and 4 g/t silver (BUUY291D05, elevation of 595 metres).

These drill-holes, along with BUSY291, are interpreted to outline a northeast-elongate zone, more than 100 metres in vertical extent and 25 x 40 metres in horizontal strike, open vertically in both directions and along strike to the southwest. Mineralization takes the form of moderately-dipping, sheeted gold-rich pyrite-Kspar veinlets, locally cross-cut by auriferous base-metal veins. This style of mineralization (“291-Style”) is interpreted as relatively high-temperature “porphyry” style and may contribute further to more bulk style gold potential of Buriticá at depth.

– Elsewhere, drilling also intersected multiple veins below or outside of the current Yaraguá mineral resource envelope, extending the vertical extents of several Yaraguá vein families. In western Yaraguá, key intercepts include:

  • 0.5 metres @ 24.6 g/t gold and 20 g/t silver (BUUY291D01, elevation of 636 metres);
  • 5.25 metres @ 6.7 g/t gold and 22 g/t silver, including 1.25 metres @ 15.9 g/t gold and 80 g/t silver (BUUY291D01, elevation of 595 metres);
  • 1.6 metres @ 8.7 g/t gold and 5 g/t silver (BUUY291D03, elevation of 613 metres);
  • 0.5 metres @ 43.5 g/t gold and 15 g/t silver (BUUY291D03, elevation of 501 metres);
  • 0.65 metres @ 17.6 g/t gold and 3 g/t silver (BUUY291D04, elevation of 620 metres); and
  • 4.6 metres @ 9.9 g/t gold and 55 g/t silver, including 1.2 metres @ 27.6 g/t gold and 180 g/t silver (BUUY291D05, elevation of 581 metres);

and, in eastern Yaraguá:

  • 3.2 metres @ 15.3 g/t gold and 28 g/t silver (BUUY305, elevation of 1,081 metres); and
  • 2.6 metres @ 8.1 g/t gold and 6 g/t silver (BUUY309, elevation of 1,085 metres).

Most of the Yaraguá vein families remain open to depth and the grades encountered in this drilling are encouraging for future mineral resource growth.

– Infill drill-holes encountered multiple vein families with grades X thicknesses that are commonly substantially greater than those expected from the current mineral resource block model for Yaraguá. Broad and/or high-grade intercepts in related master veins, in eastern Yaraguá, include:

  • 1.3 metres @ 71.2 g/t gold and 14 g/t silver (GEOMK17, MU10, elevation of 1,370 metres);
  • 6.1 metres @ 4.4 g/t gold and 29 g/t silver, including 1.2 metres @ 10.4 g/t gold and 21 g/t silver (GEOMK17, MU3, elevation of 1,278 metres);
  • 14.17 metres @ 5.6 g/t gold and 5 g/t silver, including 1.77 metres @ 24.5 g/t gold and 18 g/t silver (BUUY309, MU3, elevation of 1,025 metres);
  • 3.46 metres @ 9.0 g/t gold and 30 g/t silver (BUUY309, PRE, elevation of 1,023 metres);
  • 2.05 metres @ 66.3 g/t gold and 15 g/t silver (BUUY309, VNB, elevation of 1,018 metres);
  • 0.56 metres @ 21.6 g/t gold and 35 g/t silver (BUUY306, MUS, elevation of 1,099 metres);
  • 4.21 metres @ 12.3 g/t gold and 12 g/t silver, including 1.03 metres @ 31.9 g/t gold and 25 g/t silver (BUUY306, MU2, elevation of 1,073 metres); and
  • 0.57 metres @ 23.0 g/t gold and 62 g/t silver (BUUY306, PRE, elevation of 1,067 metres);

and, in central Yaraguá:

  • 1.0 metres @ 33.3 g/t gold and 107 g/t silver (BUUY304, MU2, elevation of 1,237 metres);
  • 0.55 metres @ 48.8 g/t gold and 30 g/t silver (BUUY307, MU2, elevation of 1,247 metres);

  • 2.45 metres @ 209 g/t gold and 52 g/t silver (BUUY307, VNBC1, elevation of 1,266 metres);
  • 8.25 metres @ 10.4 g/t gold and 15 g/t silver, including 1.0 metres @ 25.9 g/t gold and 26 g/t silver (BUUY307, VNC2 & SOF, elevation of 1,278 metres);
  • 2.9 metres @ 8.7 g/t gold and 6 g/t silver, including 1.15 metres @ 18.8 g/t gold and 10 g/t silver (BUUY313, MU, elevation of 1,218 metres);
  • 0.6 metres @ 36.4 g/t gold and 37 g/t silver (BUUY310, MU2, elevation of 1,167 metres);
  • 13.9 metres @ 5.3 g/t gold and 6 g/t silver, including 1.7 metres @ 11.2 g/t gold and 6 g/t silver (GEOMK14, MU4, elevation of 1,459 metres);
  • 2.45 metres @ 17.3 g/t gold and 13 g/t silver, including 1.3 metres @ 28.7 g/t gold and 11 g/t silver (GEOMK14, PRE, elevation of 1,447 metres);
  • 2.5 metres @ 11.6 g/t gold and 81 g/t silver, including 0.55 metres @ 43.9 g/t gold and 325 g/t silver (GEOMK14, VNAD, elevation of 1,340 metres);
  • 2.85 metres @ 12.5 g/t gold and 75 g/t silver (BUUY296, MUS1, elevation of 1,125 metres);
  • 4.5 metres @ 9.4 g/t gold and 22 g/t silver, including 1.5 metres @ 14.7 g/t gold and 6 g/t silver (BUUY296, VNE, elevation of 1,080 metres); and
  • 1.1 metres @ 20.1 g/t gold and 12 g/t silver (BUUY312, VNAD, elevation of 1,266 metres);

and, in western Yaraguá:

  • 1.28 metres @ 23.6 g/t gold and 9 g/t silver (BUUY291D01, VNB, elevation of 641 metres);
  • 2.12 metres @ 8.9 g/t gold and 35 g/t silver (BUUY291D02, FWV, elevation of 631 metres);
  • 1.25 metres @ 14.7 g/t gold and 19 g/t silver (BUUY291D03, VNB, elevation of 649 metres);
  • 1.75 metres @ 28.2 g/t gold and 25 g/t silver (BUUY291D04, MU11, elevation of 866 metres); and
  • 2.45 metres @ 14.2 g/t gold and 15 g/t silver (BUUY291D04, SOF, elevation of 693 metres).

– These and other intercepts will contribute to increased confidence levels of high-grade gold and silver mineral resources within master vein families covering large vertical and horizontal extents of the Yaraguá system. The grade X thicknesses of these veins in the 1,000-1,400-metre range of elevations are particularly encouraging as this is proximal to the main haulage developments proposed in the 2014 Preliminary Economic Assessment (the “PEA”), and also restricts the influence of areas within the Yaraguá system that were previously modelled as containing predominately low to medium precious metal grades.

“The 2014 drilling program at Yaraguá continues to achieve better results than anticipated from the May 2014 mineral resource estimate,” commented Ari Sussman, President and CEO of Continental. “We look forward to completing an updated mineral resource estimate prior to the end of this quarter and are optimistic that our internal targets will be achieved in the study.”

Details

Continental’s 100%-owned, 59,285-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. See “About Continental Gold” below for a précis of the PEA prepared in accordance with NI 43-101. This release documents the results of infill and extension drilling through the Yaraguá vein system. Significant new drill intercepts are listed below in Table I and are referenced in Figures 1, 2, 3 and 4.

* Intercepts calculated at 1 g/t gold + 50 g/t silver cut-off grades for minimum intervals of 0.5 metres, with up to 30% internal dilution. True widths not accurately known but generally are between 70% of the down-hole interval and near true width(for GEOMK14, GEOMK17 and BUUY291D-D05, about 50%). Drill-holes designated “BUUY” were collared from underground, and drill-holes designated “BUSY” were collared at surface. Holes directionally-drilled from “mother holes” (BUUYDxxx or BUSYDxxx) are designated BUUYxxxDxx or BUSYxxxDxx), as the case may be.
** Intercepts in vein domains are respectively nominated by vein code (e.g. VNC) whereas other intercepts are designated as below or outside of the current Buriticá mineral resource envelopes. Dilution is defined as new mineralization outside of modelled vein domains. Intercepts with grades X thicknesses apparently substantially greater than for the corresponding vein domains in the current mineral resource block model are also highlighted in bold.

Infill and extension drilling of Yaraguá comprised four fans (for 15 underground drill-holes) drilled from chambers set up in the Higabra Valley tunnel, at elevations around 1,170 metres (Figures 1 and 2). Drill-holes in three of the fans were broadly north-directed and shallowly-inclined to achieve very high angle intersections with master vein sets through most of the Yaraguá vein families. Two holes (GEOMK14 and GEOMK17) were drilled from surface, primarily for geotechnical purposes, but also infilled parts of the Yaraguá system at higher elevations than the underground holes were targeting. Five holes (BUUY291D01-D05) were directionally drilled off of BUUY291D, deep into western Yaraguá.

These step-out holes extended a bulk mineralized zone discovered in BUSY291 (65.1 metres @ 10.4 g/t gold and 9 g/t silver, (CNL News Release, November 12, 2012). New intercepts in this zone, below the current Yaraguá mineral resource envelope (Figures 2 and 4), include:

  • 17.38 metres @ 10.8 g/t gold and 7 g/t silver (BUUY291D01, elevation of 614 metres);
  • 10.3 metres @ 6.2 g/t gold and 5 g/t silver (BUUY291D02, elevation of 640 metres);
  • 7.95 metres @ 4.7 g/t gold and 6 g/t silver (BUUY291D03, elevation of 537 metres); and
  • 21.15 metres @ 4.6 g/t gold and 4 g/t silver (BUUY291D05, elevation of 595 metres).

These drill-holes, along with BUSY291, are interpreted to outline a northeast-elongate zone, over 100 metres in vertical extent and 25 x 40 metres in the horizontal, open to depth, upwards and to the southwest. Mineralization takes the form of moderately-dipping, sheeted gold-rich pyrite-Kspar veinlets with high lead/zinc but base-metal-poor, chemically and morphologically distinct from and locally cross-cut by auriferous base-metal veins. Selvages around the pyritic veinlets exhibit potassic, biotite-stable alteration. This mineralization (“291-Style”) is interpreted as an apparently relatively high-temperature, “porphyry” style and may contribute further to more bulk style gold potential of Buriticá at depth.

Elsewhere, drilling also intersected multiple veins below or outside of the current Yaraguá mineral resource envelope (Table 1), extending the vertical extents of several Yaraguá vein families. In western Yaraguá, key intercepts include:

  • 0.5 metres @ 24.6 g/t gold and 20 g/t silver (BUUY291D01, elevation of 636 metres);
  • 5.25 metres @ 6.7 g/t gold and 22 g/t silver, including 1.25 metres @ 15.9 g/t gold and 80 g/t silver (BUUY291D01, elevation of 595 metres);
  • 1.6 metres @ 8.7 g/t gold and 5 g/t silver (BUUY291D03, elevation of 613 metres);
  • 0.8 metres @ 16.5 g/t gold and 11 g/t silver (BUUY291D03, elevation of 605 metres);
  • 0.5 metres @ 43.5 g/t gold and 15 g/t silver (BUUY291D03, elevation of 501 metres);
  • 0.65 metres @ 17.6 g/t gold and 3 g/t silver (BUUY291D04, elevation of 620 metres);
  • 0.5 metres @ 17.8 g/t gold and 46 g/t silver (BUUY291D04, elevation of 586 metres); and
  • 4.6 metres @ 9.9 g/t gold and 55 g/t silver, including 1.2 metres @ 27.6 g/t gold and 180 g/t silver (BUUY291D05, elevation of 581metres);

and, in eastern Yaraguá:

  • 3.2 metres @ 15.3 g/t gold and 28 g/t silver, including 1.05 metres @ 30.2 g/t gold and 39 g/t silver (BUUY305, elevation of 1,081 metres); and
  • 2.6 metres @ 8.1 g/t gold and 6 g/t silver (BUUY309, elevation of 1,085 metres).

Most of the Yaraguá vein families remain open to depth and the grades encountered in this drilling are encouraging for future mineral resource growth.

Infill drill-holes encountered multiple vein families with grades X thicknesses that are commonly substantially greater than those expected (Table 1) from the current mineral resource block model for eastern, central and western Yaraguá (Figures 1, 2 and 3). Broad and/or high-grade intercepts in related master veins, in eastern Yaraguá, include:

  • 1.3 metres @ 71.2 g/t gold and 14 g/t silver (GEOMK17, MU10, elevation of 1,370 metres);
  • 6.1 metres @ 4.4 g/t gold and 29 g/t silver, including 1.2 metres @ 10.4 g/t gold and 21 g/t silver (GEOMK17, MU3, elevation of 1,278 metres);
  • 14.17 metres @ 5.6 g/t gold and 5 g/t silver, including 1.77 metres @ 24.5 g/t gold and 18 g/t silver (BUUY309, MU3, elevation of 1,025 metres);
  • 3.46 metres @ 9 g/t gold and 30 g/t silver (BUUY309, PRE, elevation of 1,023 metres);
  • 2.05 metres @ 66.3 g/t gold and 15 g/t silver (BUUY309, VNB, elevation of 1,018 metres);
  • 0.56 metres @ 21.6 g/t gold and 35 g/t silver (BUUY306, MUS, elevation of 1,099 metres);
  • 4.21 metres @ 12.3 g/t gold and 12 g/t silver, including 1.03 metres @ 31.9 g/t gold and 25 g/t silver (BUUY306, MU2, elevation of 1,073 metres);
  • 0.57 metres @ 23 g/t gold and 62 g/t silver (BUUY306, PRE, elevation of 1,067 metres); and
  • 4.8 metres @ 7.3 g/t gold and 20 g/t silver, including 1.5 metres @ 11.7 g/t gold and 22 g/t silver (BUUY305, SAV, elevation of 1,084 metres);

and, in central Yaraguá:

  • 1.0 metres @ 33.3 g/t gold and 107 g/t silver (BUUY304, MU2, elevation of 1,237 metres);
  • 0.5 metres @ 36.6 g/t gold and 23 g/t silver (BUUY304, MU5, elevation of 1,239 metres);

  • 1.7 metres @ 28 g/t gold and 8 g/t silver (BUUY307, MU4, elevation of 1,253 metres);
  • 2.45 metres @ 209.0 g/t gold and 52 g/t silver (BUUY307, VNBC1, elevation of 1,266 metres);
  • 8.25 metres @ 10.4 g/t gold and 15 g/t silver, including 1.0 metres @ 25.9 g/t gold and 26 g/t silver and 1.1 metres @ 20.3 g/t gold and 37 g/t silver (BUUY307, VNC2 and SOF, elevation of 1,278 metres);
  • 2.9 metres @ 8.7 g/t gold and 6 g/t silver, including 1.15 metres @ 18.8 g/t gold and 10 g/t silver (BUUY313, MU, elevation of 1,218 metres);
  • 0.5 metres @ 20.2 g/t gold and 27 g/t silver (BUUY313, VNBC, elevation of 1,227 metres);
  • 0.6 metres @ 36.4 g/t gold and 37 g/t silver (BUUY310, MU2, elevation of 1,167 metres);
  • 13.9 metres @ 5.3 g/t gold and 6 g/t silver, including 1.7 metres @ 11.2 g/t gold and 6 g/t silver (GEOMK14, MU4, elevation of 1,459 metres);
  • 2.45 metres @ 17.3 g/t gold and 13 g/t silver, including 1.3 metres @ 28.7 g/t gold and 11 g/t silver (GEOMK14, PRE, elevation of 1,447 metres);
  • 2.5 metres @ 11.6 g/t gold and 81 g/t silver, including 0.55 metres @ 43.9 g/t gold and 325 g/t silver (GEOMK14, VNAD, elevation of 1,340 metres);
  • 2.85 metres @ 12.5 g/t gold and 75 g/t silver (BUUY296, MUS1, elevation of 1,125 metres);
  • 4.5 metres @ 9.4 g/t gold and 22 g/t silver, including 1.5 metres @ 14.7 g/t gold and 6 g/t silver (BUUY296, VNE, elevation of 1,080 metres);
  • 0.75 metres @ 14.6 g/t gold and 3 g/t silver (BUUY312, VND, elevation of 1,261 metres); and
  • 1.1 metres @ 20.1 g/t gold and 12 g/t silver (BUUY312, VNAD, elevation of 1,266 metres);

plus, in western Yaraguá:

  • 1.28 metres @ 23.6 g/t gold and 9 g/t silver (BUUY291D01, VNB, elevation of 641 metres);
  • 2.12 metres @ 8.9 g/t gold and 35 g/t silver (BUUY291D02, FWV, elevation of 631 metres);
  • 1.25 metres @ 14.7 g/t gold and 19 g/t silver (BUUY291D03, VNB, elevation of 649 metres);
  • 1.75 metres @ 28.2 g/t gold and 25 g/t silver (BUUY291D04, MU11, elevation of 866 metres); and
  • 2.45 metres @ 14.3 g/t gold and 15 g/t silver (BUUY291D04, SOF, elevation of 693 metres).

These and other intercepts will contribute to increased confidence levels of high-grade gold and silver mineral resources within master vein families through large vertical and horizontal extents of the Yaraguá system. The grade X thicknesses of these veins in the 1,000-1,400-metre range of elevations are particularly encouraging as this is proximal to the main haulage developments proposed in the PEA and also restricts the influence of areas within Yaraguá that were previously modelled as containing predominately low to medium precious metal grades.

For additional information on the Buriticá project, please refer to the PEA (entitled “Buritica Gold Project, NI 43-101 Technical Report Preliminary Economic Assessment, Antioquia, Colombia”, and dated December 22, 2014 with an effective date of November 17, 2014), led by M3 Engineering and Technology of Tucson, Arizona, with contributions from other independent consultants including NCL Ingeneria y Construccion SPA, which was responsible for the underground mine plan for the Buriticá project. The PEA is preliminary in nature and includes inferred mineral resources that are considered to be too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty the PEA will be realized. Further, mineral resources are not mineral reserves and have not demonstrated economic viability. The PEA is available on SEDAR at www.sedar.com, on the OTCQX at www.otcmarkets.com and on the Company website at www.continentalgold.com.

Forward-Looking Statements

This press release contains or refers to forward-looking information under Canadian securities legislation, including statements regarding the estimation of mineral resources, results of the PEA, advancing the Buriticá project, exploration results, potential mineralization, potential development of mine openings, potential improvement of mining dilution grades, timing of an updated mineral resource estimate, 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 of 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” 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.
