Continental Gold Drills Broad and High-Grade Intervals in the Veta Sur Vein System at Buritica, Colombia
TORONTO, ONTARIO--(Marketwired - Jan 29, 2015) - Continental Gold Ltd. (TSX:CNL)(OTCQX:CGOOF) ("Continental" or the "Company") is pleased to announce results for 15 diamond drill-holes through the Veta Sur 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 robust mineral resource growth. The Company recently released a Preliminary Economic Assessment (the "2014 PEA") of the Buriticá Project. The 2014 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) 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 2014 PEA will be realized. Further, mineral resources are not mineral reserves and have not demonstrated economic viability.
Highlights (referenced in Figures 1 and 2)
- Drilling was successful in infilling central sections of the Veta Sur vein system through 300 metres of vertical and 300 metres of lateral extents. The Veta Sur system was also extended to the north, southwest and to depth and remains open in these directions. Two of the drill holes, which were designed to infill Veta Sur, continued through the system to the northwest, encountering new veins. Additionally, these two holes then continued past the Veta Sur system and encountered the Yaraguá vein system approximately 300 metres from the most westerly-modeled vein family.
- In central Veta Sur, drill holes encountered multiple vein families with grades X thicknesses that are substantially greater than those expected from the current mineral resource block model. Broad and/or high-grade intercepts and related master veins include:
- 10.85 metres @ 56.4 g/t gold and 163 g/t silver, including 2.55 metres @ 108.1 g/t gold and 320 g/t silver (BUSY369D04, V42, elevation of 1,315 metres);
- 9.75 metres @ 26.4 g/t gold and 91 g/t silver, including 1.68 metres @ 105.0 g/t gold and 366 g/t silver (BUSY369D07, V42, elevation of 1,324 metres);
- 12.0 metres @ 27.3 g/t gold and 46 g/t silver, including 1.35 metres @ 142.8 g/t gold and 195 g/t silver (BUSY369D11, V42, elevation of 1,272 metres);
- 0.6 metres @ 116 g/t gold and 109 g/t silver (BUUY289D02, V34, elevation of 1,185 metres);
- 14.2 metres @ 12.2 g/t gold and 17 g/t silver, including 2.15 metres @ 65.6 g/t gold and 78 g/t silver (BUUY289D02, V31, elevation of 1,152 metres);
- 0.5 metres @ 107.5 g/t gold and 91 g/t silver (BUUY289D03, V41, elevation of 1,237 metres);
- 12.7 metres @ 14.8 g/t gold and 87 g/t silver, including 2.0 metres @ 74.9 g/t gold and 468 g/t silver (BUUY289D03, V31, elevation of 1,186 metres); and
- 1.18 metres @ 97.4 g/t gold and 6 g/t silver (BUUY289D04, V34, elevation of 1,217 metres).
- These and other intercepts in the 1,100-1,400-metre range of elevations will contribute to increased confidence levels of high-grade gold and silver mineral resources in master veins of central Veta Sur. The grade X thicknesses of these veins are encouraging for future development of an area that is close to mining and haulage development proposed in the 2014 PEA.
- Elsewhere in central to western Veta Sur, drilling intersected multiple veins below or to the southwest of the current mineral resource envelope, significantly extending the lateral and vertical extents of northern vein families in this area. Key intercepts, in relation to the Veta Sur mineral resource envelope, include:
- 5.75 metres @ 18.6 g/t gold and 31 g/t silver, including 1.3 metres @ 58.6 g/t gold and 78 g/t silver (BUSY369D09, elevation of 1,360 metres, below mineral resource envelope);
- 0.5 metres @ 2.7 g/t gold and 903 g/t silver (BUSY369D10, elevation of 1,176 metres, outside mineral resource envelope);
- 1.2 metres @ 4.7 g/t gold and 853 g/t silver (BUUY289D06, elevation of 1,170 metres, below mineral resource envelope); and
- 4.75 metres @ 5.1 g/t gold and 13 g/t silver (BUUY289D06, elevation of 975 metres, outside mineral resource envelope).
These and other extensions of the Veta Sur system shown in Table 1 are all in proximity to mining development proposed in the 2014 PEA.
- To the north and west of the current Veta Sur mineral resource envelope, two drill holes encountered multiple families of veins that are interpreted to represent as-yet unmodelled northern Veta Sur vein families and also far western extensions of the Yaraguá vein system. Significant intercepts include:
- 1.6 metres @ 7.4 g/t gold and 41 g/t silver (BUSY369D10, elevation of 1,081 metres);
- 7.86 metres @ 7.2 g/t gold and 29 g/t silver, including 2.14 metres @ 19.1 g/t gold and 77 g/t silver (BUUY289D05, elevation of 762 metres); and
- 0.93 metres @ 11.5 g/t gold and 2 g/t silver (BUUY289D05, elevation of 718 metres).
"2014 infill and extension drilling at Veta Sur continuously intersected superior results compared to the current mineral resource estimate," commented Ari Sussman, CEO of Continental. "We look forward to the next mineral resource estimate for the Buriticá project, anticipated in late Q2 2015, and expect to see growth in both the Measured and Indicated ounces."
Details
Continental's 100%-owned, 62,348-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 2014 PEA prepared in accordance with NI 43-101. This release documents the results of infill and extension drilling to the north and northwest through central Veta Sur. Significant new drill intercepts are listed below in Table I and are referenced in Figures 1 and 2.

* 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 30% of the down-hole interval and near true width. 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. V34) whereas other intercepts are designated as below or outside of the current Veta Sur mineral resource envelopes. Intercepts with grades X thicknesses apparently significantly greater than for the corresponding vein domains in the current resource block model are also highlighted in gray. |
Eight holes (BUSY369D04 to BUSY369D11, inclusive) and a further six holes (BUUY289D01 to BUUY289D06, inclusive) were respectively deviated and directionally drilled from "mother" holes BUSY369D and BUUY289D, to the south of Veta Sur. The deviated holes were drilled to the north and northwest across the Veta Sur system, infilling central areas of the mineral resource envelope as well as targeting potential extensions to depth (Figures 1 and 2). Holes drilled to the northwest also targeted potential southwest extensions of the deeper Veta Sur and far western Yaraguá systems (Figures 1 and 2).
In central Veta Sur, drill holes encountered multiple vein families over 300 metres of vertical and lateral extents with apparent grades X thicknesses generally comparable with or significantly greater than those expected from the current mineral resource block model. Broad and/or high-grade intercepts and related master veins include:
- 10.85 metres @ 56.4 g/t gold and 163 g/t silver, including 2.55 metres @ 108.1 g/t gold and 320 g/t silver (BUSY369D04, V42, elevation of 1,315 metres);
- 0.7 metres @ 77.6 g/t gold and 54 g/t silver (BUSY369D06, V41, elevation of 1,286 metres);
- 9.75 metres @ 26.4 g/t gold and 91 g/t silver, including 1.68 metres @ 105 g/t gold and 366 g/t silver (BUSY369D07, V42, elevation of 1,324 metres);
- 12.0 metres @ 27.3 g/t gold and 46 g/t silver, including 1.35 metres @ 142.8 g/t gold and 195 g/t silver (BUSY369D11, V42, elevation of 1,272 metres);
- 0.6 metres @ 116.0 g/t gold and 109 g/t silver (BUUY289D02, V34, elevation of 1,185 metres);
- 14.2 metres @ 12.2 g/t gold and 17 g/t silver, including 2.15 metres @ 65.6 g/t gold and 78 g/t silver (BUUY289D02, V31, elevation of 1,152 metres);
- 0.5 metres @ 107.5 g/t gold and 91 g/t silver (BUUY289D03, V41, elevation of 1,237 metres);
- 12.7 metres @ 14.8 g/t gold and 87 g/t silver, including 2.0 metres @ 74.9 g/t gold and 468 g/t silver (BUUY289D03, V31, elevation of 1,186 metres); and
- 1.18 metres @ 97.4 g/t gold and 6 g/t silver (BUUY289D04, V34, elevation of 1,217 metres).
These and other intercepts (highlighted in Table I) in the 1,100 to 1,400-metre range of elevations will contribute to increased confidence levels of high-grade gold and silver mineral resources in master veins of central Veta Sur. The grade X thicknesses encountered are particularly encouraging for potential mining in an area that is close to main haulage development proposed in the 2014 PEA.
Elsewhere in central to western Veta Sur, drilling intersected multiple veins below or to the southwest of the current mineral resource envelope (Table 1), substantially extending the lateral and vertical extents of northern vein families in this area (Figures 1 and 2). Key intercepts and their relationships to the Veta Sur mineral resource envelope, include:
- 5.75 metres @ 18.6 g/t gold and 31 g/t silver, including 1.3 metres @ 58.6 g/t gold and 78 g/t silver (BUSY369D09, elevation of 1,360 metres, below mineral resource envelope);
- 0.5 metres @ 2.7 g/t gold and 903 g/t silver (BUSY369D10, elevation of 1,176 metres, outside mineral resource envelope);
- 1.2 metres @ 4.7 g/t gold and 853 g/t silver (BUUY289D06, elevation of 1,170 metres, below mineral resource envelope); and
- 4.75 metres @ 5.1 g/t gold and 13 g/t silver (BUUY289D06, elevation of 975 metres, outside mineral resource envelope).
These and other extensions of the Veta Sur system shown in Table 1 are all in proximity to mining development proposed in the 2014 PEA.
To the north and west of the current Veta Sur mineral resource envelope, two drill holes (BUSY369D10 (from 517 metres down-hole) and BUUY289D05 (from 700 metres down-hole) encountered multiple families of veins that are interpreted to represent as-yet unmodelled northern Veta Sur vein families, and also the farthest yet-drilled western extensions of the Yaraguá vein system (Figure 1). Significant intercepts include:
- 1.6 metres @ 7.4 g/t gold and 41 g/t silver (BUSY369D10, elevation of 1,081 metres);
- 7.86 metres @ 7.2 g/t gold and 29 g/t silver, including 2.14 metres @ 19.1 g/t gold and 77 g/t silver (BUUY289D05, elevation of 762 metres); and
- 0.93 metres @ 11.5 g/t gold and 2 g/t silver (BUUY289D05, elevation of 718 metres).

About Continental Gold
Continental Gold Ltd. is an advanced-stage exploration and development company with an extensive portfolio of 100%-owned gold projects in Colombia. Spearheaded by a team with over 40 years of exploration and mining experience in Colombia, the Company is focused on advancing its high-grade Buriticá gold project to production. On November 17, 2014, the Company announced the 2014 PEA, the results of which included an 18-year mine life based on 20,055,000 tonnes grading 7.80 g/t gold and 19.35 g/t silver, resulting in 4,777,000 ounces of recovered gold and 7,088,000 ounces of recovered silver, and utilized the May 2014 mineral resource estimate prepared in accordance with NI 43-101. The 2014 PEA concludes an after-tax net present value at a 5% discount of $1.08 billion and an after-tax internal rate of return of 31.5% on an initial capital cost of $390.3 million with a payback of 2.8 years. The 2014 PEA technical report is available on SEDAR at www.sedar.com and on the Company website at www.continentalgold.com.
In August 2012, Continental achieved an important milestone, receiving formal approval for the modification of its existing Environmental Impact Assessment. The amendment allows the Company to build a six-kilometre switchback road and begin underground development by constructing a one-kilometre access tunnel. With a goal of being the newest hard rock gold producer in Colombia, Continental has achieved major advances with the access tunnel, which is providing access for underground drilling and will eventually be used for commercial production. A Phase VII drill program is underway at the Buriticá project to further delineate the mineral resources and drill new target zones identified within its concessions.
Additional details on the Buriticá project and the rest of Continental's suite of gold exploration properties are available 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 2014 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.
