TORONTO, ONTARIO--(Marketwired - April 3, 2013) - Continental Gold Limited (TSX:CNL)(OTCQX:CGOOF) ("Continental" or the "Company") is pleased to announce results for 11 diamond drill-holes and near-surface sampling in the La Estera and Yaraguá areas, as part of the Company's ongoing exploration program at the Buriticá Project in Antioquia, Colombia. Ten drills are currently on site as part of the Company's Phase IV, minimum 95,000-metre diamond drill program for 2013.
Highlights
La Estera Area (Figures 1 and 2)
- Step out drilling in the La Estera area has extended the Laurel family of veins approximately 200 metres to the west. High-grade intercepts in BUSY332 include:
- 9.83 metres @ 16.1 g/t gold and 50 g/t silver, including 3.34 metres @ 38.9 g/t gold and 111 g/t silver (elevation of 1,036 metres); and
- 1.75 metres @ 36.7 g/t gold and 182 g/t silver (elevation of 1,063 metres).
- BUSY333 and BUSY338 are interpreted to have intersected the Laurel family of veins 400-500 metres to the east of and at higher elevations than in BUSY332. Intercepts include:
- 0.3 metres @ 20.6 g/t gold and 29 g/t silver (BUSY333, elevation of 1,313 metres);
- 0.4 metres @ 18.2 g/t gold and 7 g/t silver (BUSY338, elevation of 1,574 metres);
- 1.23 metres @ 10.8 g/t gold, 97 g/t silver and 5.3% zinc (BUSY338, elevation of 1,459 metres); and
- 2.36 metres @ 9.2 g/t gold, 135 g/t silver and 9.0% zinc (BUSY338, elevation of 1,439 metres).
- These drilling results are consistent with a lateral extent of the Laurel vein family of more than 500 metres and vertical extents of 500-1,000 metres, open to depth and to the east and west.
- Further south, BUSY332 has extended mineralization in the La Estrella vein family to the west of previous drilling, whereas BUSY333 has intersected this vein system more than 1,000 vertical metres below related surface mineralization.
- In the northeast portion of the La Estera area, located just south of the Yaraguá vein system, significant gold-silver mineralization has been encountered from both sampling of the Veta Sur decline ("Rampa Sur") and surface sampling in the vicinity of the decline portal. Assay results include:
- 1.5 metres @ 13.9 g/t gold and 5 g/t silver (Surface, elevation of 1,729 metres); and
- 1.0 metres @ 7.9 g/t gold, 12 g/t silver and 8.5% zinc (Rampa Sur, elevation of 1,705 metres).
- In the southeastern La Estera area, BUSY330 intersected several broad intervals of base metal-rich, gold-silver mineralization in the vicinity of the La Mano vein family, including:
- 12.95 metres @ 3.8 g/t gold and 10 g/t silver, including 0.95 metres @ 13.4 g/t gold, 21 g/t silver and 2.5% zinc (elevation of 1,213 metres); and
- 9.5 metres @ 2.7 g/t gold and 24 g/t silver (elevation of 1,182 metres).
- In the central-east part of the La Estera area, individual samples from two historic and narrow workings on the east-west trending La Mano vein family assayed 15.7 g/t gold, 254 g/t silver, 17.3% zinc and also 25.2 g/t gold, 27 g/t silver and 2.7% zinc. These results, together with BUSY319 (see December 13, 2012 news release) confirm a minimum strike-length of 150 metres for this vein family, open laterally and to depth.
Yaraguá Vein System (Figures 1 and 3)
- In eastern Yaraguá, four drill-holes transected the central and northern vein families. Intercepts to the north of the October 2012 mineral resource estimate, prepared in accordance with National Instrument 43-101 ("NI 43-101"), include:
- 6.3 metres @ 7.0 g/t gold and 60 g/t silver, including 0.8 metres @ 35.2 g/t gold, 366 g/t silver and 9.3% zinc (BUUY099, elevation of 1,325 metres);
- 0.7 metres @ 22.3 g/t gold, 750 g/t silver and 4.6% zinc (BUUY099, elevation of 1,279 metres); and
- 0.6 metres @ 10.8 g/t gold and 117 g/t silver (BUUY100, elevation of 1,242 metres).
These and other results add further definition to extensions of the Vein A, Vein AD and Vein D packages, the most northerly in the Yaraguá vein system.
- The eastern Yaraguá drill-holes otherwise intersected veins with grades and thicknesses generally consistent with the current mineral resource model, with the exception of the following intercepts, which exhibited substantially greater apparent grades and thicknesses than in the current mineral resource model, including:
- 1.0 metres @ 34.6 g/t gold and 4 g/t silver (BUUY099, PRE vein, elevation of 1,376 metres);
- 1.7 metres @ 2.1 g/t gold and 350 g/t silver, (BUUY099, VNC, elevation of 1,369 metres); and
- 2.0 metres @ 12.5 g/t gold and 9 g/t silver (BUUY100, HWV, elevation of 1,351 metres).
- BUUY101, drilled southwards through the central and southern Yaraguá vein families into Yaraguá South, encountered intercepts in the VNB, VNE and Murcielagos vein packages with apparent grade and thicknesses substantially greater than those in the current mineral resource model, including:
- 1.1 metres @ 66.7 g/t gold and 8 g/t silver (VNB, elevation of 1,504 metres);
- 4.5 metres @ 6.2 g/t gold and 15 g/t silver (VNE, elevation of 1,491 metres); and
- 34.7 metres @ 2.7 g/t gold and 10 g/t silver, including 0.5 metres @ 8.9 g/t gold and 18 g/t silver (MU2 and MU, elevations of 1,481 metres and 1,468 metres, respectively).
Otherwise, BUUY101 intersected veins with grades and thicknesses generally consistent with the current mineral resource model until terminating in the Yaraguá South area with vein intersections outside of the current mineral resource envelopes.
"Step-out drilling along strike and at depth and surface sampling continues to deliver encouraging results in the La Estera area," commented Ari Sussman, CEO. "Drilling at Yaraguá continues to increase the confidence level in the mineral resource estimate and encounter mineralization outside of the current resource envelope. We are excited that our exploration program has recently increased with the addition of three new drill rigs as part of our Phase IV drill program. Our aim is to continue to drill the Yaraguá and Veta Sur vein systems and to aggressively test the new exploration targets in 2013."
Details
Continental's 100%-owned, 57,588-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 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 précis of the updated mineral resource estimates for the Buriticá project prepared in accordance with NI 43-101. This release documents the results of infill and extension drilling of the Yaraguá vein system and also results of additional drilling and near surface sampling in the La Estera area to the south of the Yaraguá and Veta Sur vein systems.

| *Intercepts calculated at 1 g/t gold + 30 g/t silver cut-off grades for minimum intervals of 0.3 metres, with up to 30% internal dilution. True widths not accurately known but generally are between 30% and actual true width of the down-hole interval. Drill-holes designated "BUUY" were collared from underground, whereas drill-holes designated "BUSY" were collared at surface. Assay results for BUSY338 received thus far are only for intervals between 183.5 metres to 416.65 metres down-hole. |
Four holes were drilled to clarify the distribution of mineralization in the La Estera area. The most westerly of these is south-drilled BUSY323, which intersected (from 314.5 to 441 metres down-hole, Table I) several veins, mainly with relatively high silver/gold. These vein sets are interpreted to represent extensions, at high elevations (1,500-1,600 metres above sea-level), of the Veta Sur system, some 300 metres to the southwest of the current Veta Sur resource envelope (Figure 1). Deep intersections (850 and 828 metres above sea-level) with high gold/silver in north-drilled BUSY332 may also be extensions of the Veta Sur system (Figure 2).
BUSY332 encountered a high silver/gold vein at an elevation of 1,400 metres (Table I), extending the La Estrella vein system 50 metres to the west of previous intersections, whereas BUSY333 intersected the La Estrella system at an elevation of 784 metres above sea-level, around 1,000 metres below surface mineralization in this system. The La Estrella system remains open to the east.
Further down-hole, BUSY332 intersected multiple veins in the Laurel family, extending this vein system approximately 200 metres to the west of previous drilling. High-grade intercepts include:
- 1.75 metres @ 36.7 g/t gold and 182 g/t silver (from 902.6 metres down-hole, elevation of 1,063 metres); and
- 9.83 metres @ 16.1 g/t gold and 50 g/t silver, including 3.34 metres @ 38.9 g/t gold and 111 g/t silver (from 932.17 metres down-hole, elevations of 1,036 metres).
Both of these intercepts are sulphide-rich, the former exhibiting moderate zinc and lead contents, the latter exhibiting low base-metal values but abundant pyrrhotite plus pyrite, similar to other deep intercepts at the Buriticá project.
BUSY333 and BUSY338 are interpreted to have intersected the Laurel vein family 400-500 metres to the east of and at higher elevations than in BUSY332, with high-grade intercepts including:
- 0.3 metres @ 20.6 g/t gold and 29 g/t silver (BUSY333, from 533.50 metres down-hole, elevation of 1,313 metres);
- 0.4 metres @ 18.2 g/t gold and 7 g/t silver (BUSY338, from 221.0 metres down-hole, elevation of 1,574 metres);
- 1.23 metres @ 10.8 g/t gold, 97 g/t silver and 5.3% zinc (BUSY338, from 349.95 metres down-hole, elevation of 1,459 metres); and
- 2.36 metres @ 9.2 g/t gold, 135 g/t silver and 9.0% zinc (BUSY338, from 372.09 metres down-hole, elevation of 1,439 metres).
These drilling results are consistent with a lateral extent of the Laurel vein family of more than 500 metres and vertical extents of 500-1,000 metres, open at depth and to the east and west. Demonstration of the continuity of individual vein sets within the Laurel vein family requires more closely spaced drilling and the vein family appears to contain both circa east-west and north-south striking gold-silver vein mineralization.
Surface sampling in and nearby Rampa Sur, the decline advancing towards the Veta Sur vein system, encountered previously unknown gold-silver vein mineralization in the northeastern La Estera area located south of the Yaraguá vein system. Sampling highlights are summarized in Table II (below) and referenced in Figures 1 and 2.

| *Intercepts calculated at 1 g/t gold + 30 g/t silver cut-off grades for minimum intervals of 0.3 metres, with up to 30% internal dilution. Tabulated widths approximate true widths. |
Vein sets exhibit both high and low gold/silver and are steeply dipping with circa east-northeast and also north-northwest strikes. The surrounding area is largely undrilled, but is geochemically anomalous in gold, silver and zinc. Further work is required to establish vein extents and continuity.
In the southeastern La Estera area, BUSY330 intersected several broad intervals of base metal-rich, gold-silver mineralization including:
- 5.25 metres @ 2.1 g/t gold, 30 g/t silver and 4.5% zinc (from 162.2 metres down-hole, elevation of 1,247 metres);
- 12.95 metres @ 3.8 g/t gold and 10 g/t silver, including 0.95 metres @ 13.4 g/t gold, 21 g/t silver and 2.5% zinc (from 203.55 metres down-hole, elevation of 1,213 metres); and
- 9.5 metres @ 2.7 g/t gold and 24 g/t silver (from 240.50 metres down-hole, elevation of 1,182 metres).
These intercepts appear to exhibit both circa east-west and north-south vein orientations and contribute further to the view that the vicinity of the La Mano vein system may contain areas of potentially bulk mineable mineralization.
Assays of samples from narrow openings on an east-west trending, high-grade vein in the La Mano vein family are tabulated below. Together with BUSY319 (see December 13, 2012 news release), these results confirm a minimum strike length of 150 metres for this vein, which remains open laterally and at depth.

| *Intercepts calculated at 1 g/t gold + 30 g/t silver cut-off grades for minimum intervals of 0.3 metres, with up to 30% internal dilution. True widths not accurately known but generally are between 30% and actual true width of the down-hole interval. Drill-holes designated "BUUY" were collared from underground, whereas drill-holes designated "BUSY" were collared at surface. |
In eastern Yaraguá, four drill-holes transected the central and northern vein families. Intercepts to the north of the current Yaraguá mineral resource envelope include:
- 6.3 metres @ 7.0 g/t gold and 60 g/t silver, including 0.80 metres @ 35.2 g/t gold, 366 g/t silver and 9.3% zinc (BUUY099, from 130.80 metres down-hole, elevation of 1,325 metres);
- 0.7 metres @ 22.3 g/t gold, 750 g/t silver and 4.6% zinc (BUUY099, from 236.30 metres down-hole, elevation of 1,279 metres);
- 0.6 metres @ 10.8 g/t gold and 117 g/t silver (BUUY100, from 209.45 metres down-hole, elevation of 1,242 metres); and
- 1.0 metres @ 7.1 g/t gold and 6 g/t silver (BUUY102, from 216 metres down-hole, elevation of 1,207 metres).
These and previous drilling results add further definition to extensions of the Vein A, Vein AD and Vein D packages, the most northerly in the Yaraguá vein system.
The eastern Yaraguá drill-holes otherwise intersected veins with grades and thicknesses generally consistent with the current mineral resource model. Drill-hole intercepts exhibiting substantially greater apparent thicknesses and/or higher grades than in the current resource model include:
- 1.0 metres @ 34.6 g/t gold and 4 g/t silver (BUUY099, PRE vein, elevation of 1,376 metres);
- 1.7 metres @ 2.1 g/t gold and 350 g/t silver, (BUUY099, VNC, elevation of 1,369 metres); and
- 2.0 metres @ 12.5 g/t gold and 9 g/t silver (BUUY100, HWV, elevation of 1,351 metres).
BUUY101, drilled southwards through the central and southern Yaraguá vein families into Yaraguá South, encountered intercepts in the VNB, VNE and Murcielagos vein packages with apparent grade and thicknesses substantially greater than those in the current mineral resource model, including:
- 1.1 metres @ 66.7 g/t gold and 8 g/t silver (VNB package, elevation of 1,504 metres);
- 8.2 metres @ 2.5 g/t and 7 g/t silver (VNB package, elevation of 1,503 metres);
- 4.5 metres @ 6.2 g/t gold and 15 g/t silver (VNE, elevation of 1,491 metres); and
- 34.7 metres @ 2.7 g/t gold and 10 g/t silver, including 0.5 metres @ 8.9 g/t gold and 18 g/t silver (MU2 and MU, elevation of 1,481 metres and 1,468 metres, respectively).
Otherwise, BUUY101 intersected veins with grades and thicknesses generally consistent with the current mineral resource model. The drill-hole terminated in the Yaraguá South area with vein intersections at 1,377 metres (0.5 metres @ 7.9 g/t gold and 4 g/t silver) and also 1,365 metres above sea-level, outside of the Yaraguá and Veta Sur mineral resource envelopes.

For additional technical information on the Buriticá project, please refer to the Company's technical report (the "Technical Report") entitled "2012 Mineral Resource Estimate of the Buriticá Gold Project, Colombia" dated November 15, 2012 with an effective date of October 22, 2012, prepared by Andrew J Vigar, BAppSc Geo, FAusIMM, MSEG, and Martin Recklies, BAppSC Geo, MAIG, each of Mining Associates Pty Limited, available on SEDAR at www.sedar.com, on the OTCQX at www.otcmarkets.com and on the Company website at www.continentalgold.com.
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 IV drill program is underway at the Buriticá project to further delineate the mineral resource and drill new target zones identified within its concessions.
An animation video providing an overview of the Buriticá project and the exploration potential is available in the following link: http://bit.ly/Z6HBh9. Please note that any future production decision will be based on the positive outcome of a pre-feasibility study in 2014.
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, exploration results, potential mineralization, exploration and mine development plans, and timing of the commencement of operations, and is based on current expectations that involve a number of business risks and uncertainties. Forward-looking statements are subject to significant risks and uncertainties, and 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, 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 forward-looking statements are subject to significant risks and uncertainties, and other factors that could cause actual results to differ materially from expected results. Readers should not place undue reliance on forward-looking statements. 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.
