Continental Gold Drills 10.5 metres @ 108 g/t Gold in Yaragua and Hits with Step-out Drilling in the Yaragua and San Agustin Systems at its Buritica Project, Colombia
(firmenpresse) - TORONTO, ONTARIO -- (Marketwired) -- 06/17/13 -- Continental Gold Limited (TSX: CNL)(OTCQX: CGOOF) ("Continental" or the "Company") is pleased to announce results for 13 diamond drill-holes in the Yaragua and San Agustin vein systems, as part of the Company's ongoing exploration program at the Buritica Project in Antioquia, Colombia. Nine drills are currently on site as part of the Company's Phase IV diamond drill program for 2013.
Highlights (Referenced in Figures 1 and 2)
"The Company continues to be aggressive with its exploration efforts with nine drill rigs turning, and results are impressive," commented Ari Sussman, CEO. "Additionally, underground development and detailed engineering continue within planned parameters, further details of which will be provided in the coming weeks."
Details
Continental's 100%-owned, 57,594-hectare project, Buritica, 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 Yaragua and Veta Sur systems) are central to this land package. The Yaragua system has been drill-outlined along 900 metres of strike and 1,300 vertical metres and partially sampled in underground developments. The Veta Sur system has been drill intersected along 570 metres of strike and 1,180 vertical metres. 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 precis of the updated mineral resource estimates for the Buritica project prepared in accordance with National Instrument 43-101 ("NI 43-101"). This news release documents the results of infill and extension drilling of the Yaragua vein systems and further drilling to the north of this system into the San Agustin area.
Significant new drill intercepts are listed below in Table I and are referenced in Figures 1 and 2.
Three holes (BUUY105, BUUY108 and BUUY114, Figures 1 and 2) were drilled in eastern Yaragua to infill and extend the Yaragua mineral resource model and also to examine potential extensions into the eastern San Agustin area. Each drill-hole intersected multiple families of veins. Intercepts within the current mineral resource envelope were generally consistent with the model. However, BUUY114 made several intersections of significantly higher grade and thickness than for comparable locations in the current mineral resource model, including:
This intercept, characterized by Stage II visible gold-mineralization, is interpreted to be part of a broad high-grade subzone across the central vein family in eastern Yaragua and is open vertically. Other significant intercepts in BUUY114 include:
Each of the eastern Yaragua holes also intersected the northerly vein packages below or to the north of the current mineral resource envelope. Significant intercepts, representing the extensions of currently modeled veins, include:
Intersections (Table I) in BUUY105 (from 300 metres down-hole), BUUY108 (from 320 metres down-hole) and BUUY114 (from 298 metres down-hole), north of VNA and representing the south-eastern San Agustin vein families, include:
BUSY339 was drilled to transect deeper parts of the central Yaragua system. Near collar, at relatively shallow depth, the drill-hole intersected four silver-rich veins (from 205-320 metres down-hole, Table I). Further north and deeper, the drill-hole cut the depth extensions of all currently modeled vein domains, with intercepts all below the current mineral resource envelope. Highlighted intercepts include:
BUSY339 intersections below 1,128 metres down-hole (Table I) represent vein domains deep in the San Agustin system.
BUSY335 and BUSY341 were drilled to transect the central-western Yaragua system at depth. BUSY341 was lost at shallow depth but this drill-hole (from 189 metres down-hole, Table I) and BUSY335 (to 465 metres down-hole, Table I) intersected silver-rich veins in Yaragua South. BUSY335 made significant intercepts outside of the current mineral resource envelope, including:
and significant intercepts within the envelope:
Two holes (BUUY113 and BUUY117) to test the central and northern vein families were also drilled in central-western Yaragua. Both drill-holes encountered some intercepts with significantly higher grades and/or thicknesses than in the current mineral resource model, including:
BUUY117 also intersected the following significant intercept outside the current mineral resource envelope:
Four holes (BUUY104, BUUY106, BUUY107 and BUUY111) were also drilled in central-western Yaragua to infill the central and southern vein packages in this area. Intercepts, with significantly higher grades and/or thicknesses than in the current mineral resource model, include:
Significant intercepts outside of the current mineral resource envelope include:
BUSY340 was drilled to transect the western San Agustin system at shallow to moderate depths and also through western Yaragua at greater depths (Figure 1). From collar to about 870 metres down-hole (Table 1), BUSY340 intersected several vein families in the San Agustin system. Higher-grade intercepts include:
The latter intercepts align vertically with surface sampling and also with intercepts in BUSY324 (see February 12, 2013 news release) some 100-150 metres to the east and at 400-500 metres lower elevations, consistent with large depth extents of mineralization in western San Agustin.
Further down-hole and to the south, some 200 metres west of the current Yaragua mineral resource envelope, BUSY340 made several significant intercepts, including:
The latter two intercepts are 190 vertical metres above the broad high-grade intersection (65.1 metres (at) 10.4 g/t gold and 9 g/t silver, including 1.62 metres (at) 192 g/t gold and 91 g/t silver) in BUSY291 (see November 12, 2012 news release); Figure 2. The BUSY340 intercepts could represent west extensions of the deep Yaragua system or a vein system with large vertical extent but more northerly orientation.

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 commenced the construction of the access tunnel, which will initially provide access for underground drilling and eventually used for commercial production. A Phase IV drill program is underway at the Buritica project to further delineate the mineral resource and drill new target zones identified within its concessions.
An animation video providing an overview of the Buritica project and the exploration potential is available in the following link: . Please note that any future production decision will be based on the positive outcome of a pre-feasibility study in Q4 2014/Q1 2015.

These forward-looking statements are made as of the date hereof and 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.
