TORONTO, ONTARIO--(Marketwired - Jan. 9, 2014) - Continental Gold Limited (TSX:CNL)(OTCQX:CGOOF) ("Continental" or the "Company") is pleased to announce results for 11 diamond drill-holes from the Veta Sur and eastern Laurel vein systems as part of the Company's 2013 exploration program at the Buriticá project in Antioquia, Colombia. Drilling will continue in 2014 with the goal of delivering robust mineral resource growth and upgrading inferred resources into the measured and indicated categories.
Highlights (referenced in Figures 1 and 2)
"Drilling continues to successfully infill and vertically extend existing veins while encountering new veins outside of the current mineral resource block model," commented Ari Sussman, CEO. "The updated mineral resource estimate remains on track for release in the first quarter of 2014 and will include the current drill results."
Continental's 100%-owned, 58,773-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 900 metres of strike and 1,300 vertical metres and partially sampled in underground developments. The Veta Sur system has been drill-outlined along 700 metres of strike and 1,300 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 précis of the updated mineral resource estimates for the Buriticá projectprepared in accordance with NI 43-101. This release documents the results of extension and infill drilling of the Veta Sur system and, to the south of this, the Laurel vein system. Significant new drill intercepts are listed below in Table I and are referenced in Figures 1 and 2.
Table I: Drilling Highlights
|Gold (g/t)||Silver (g/t)||Zinc
|*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% and near true width (e.g. BUUY173 and BUUY178) of the down-hole interval. Drill-holes designated "BUUY" were collared from underground, and drill-holes designated "BUSY" were collared at surface.|
Four holes (BUSY355, BUSY360, BUSY359 and BUUY176) were drilled from the south to the north to transect the Veta Sur vein system over a strike length of 300 metres and through a substantial range of elevations. Intercepts to the south of the current Veta Sur mineral resource envelope include:
These and other intercepts represent previously unmodeled southern Veta Sur vein families, which remain open laterally and to depth.
Nine drill holes (including the four holes mentioned above) intersected multiple families of veins to the north of the current Veta Sur mineral resource, with high-grade gold and/or silver intercepts including:
Intercepts within BUUY202 (from 372 metres down-hole), BUUY183 (from 328 metres down-hole) and BUUY178 (from 223 metres down-hole) potentially represent far-west extensions of the Yaraguá vein system over a 500-metre range of elevations with the silver-to-gold ratio varying between moderate to high.
Intercepts to the south of the aforementioned holes - BUSY355 (699-735 metres down-hole), BUSY359 (349-388 metres down-hole), BUSY360 (627-717 metres down-hole), BUUY173 (159-274 metres down-hole), BUUY178 (223-237 metres down-hole), BUUY194 (180-303 metres down-hole) and BUUY176 (265-455 metres down-hole) - represent previously unmodeled northern vein families of the Veta Sur vein system. These vein families have now been intersected over 400 metres of strike length and at depth ranges of 1,000 metres, and typically appear to show increasing gold/silver with depth. The northern Veta Sur vein families remain open laterally and to depth.
Elsewhere, several drill-holes extended parts of the Veta Sur mineralized envelope to greater depths than the current mineral resource model, with intercepts (from northeast to southwest) including:
Several drill-holes extended several veins to higher elevations than in the current mineral resource model, with intercepts including:
Drill intersections within the current Veta Sur mineral resource envelope are generally consistent with grade X thicknesses of comparable areas of the current mineral resource model. Some intercepts were of significantly higher grades and/or apparent thicknesses, including:
To the south of the Veta Sur vein system, BUSY358 and BUSY360 intersected the eastern Laurel vein family at high elevations, with highlighted intercepts including:

About Continental Gold
Continental Gold Limited 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 October 1, 2012, the Company announced an updated mineral resource estimate for the Buriticá project prepared in accordance with NI 43-101 which covers two major vein systems, with combined Measured and Indicated mineral resource of 3,740,000 tonnes of mineralized material containing 1,640,000 ounces of gold grading 13.6 g/t gold, 4,600,000 ounces of silver grading 38 g/t silver, and 55,800,000 pounds of zinc grading 0.7% zinc. The combined Inferred mineral resource is 13,330,000 tonnes of mineralized material containing 3,760,000 ounces of gold grading 8.8 g/t gold, 14,200,000 ounces of silver grading 33 g/t silver and 156,500,000 pounds of zinc grading 0.5% zinc.
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 V drill program is underway at the Buriticá project to further delineate the mineral resource 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.

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.
