Continental Gold Drills 25.45 m @ 12.02 g/t Au and 57.4 g/t Ag at Veta Sur and Extends the Veta Sur Mineralization 350 m Vertically with the First Drill-Hole of the Buritica Deep Drilling Program
(firmenpresse) - TORONTO, ONTARIO -- (Marketwire) -- 08/31/11 -- Continental Gold Ltd. ("Continental" or the "Company") (TSX: CNL) is pleased to announce results for 16 diamond drill-holes from the Company's ongoing program at its Buritica Project in Antioquia, Colombia. Over 80,000 metres of diamond drilling have been completed on the property to date and nine drills are currently on schedule to complete approximately 100,000 metres of surface and underground drilling by the end of 2011.

Details
Continental's 100%-owned, 22,457-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 system and the Veta Sur system, Figure 1) are central to this land package. The Yaragua System has been drill-outlined along 550 metres of strike and 600 vertical metres and partially sampled in underground developments. The Veta Sur system has been drill intersected along 500 metres of strike and over 900 vertical metres, including the latest visual intercept (Figure 2). Both systems are characterized by multiple, steeply dipping veins and broader, more disseminated mineralization and both remain open at depth at high grades.
Veta Sur
Significant new drill intercepts in the Veta Sur system are tabulated below:
Drilling at Veta Sur has focused on and been successful at:
Two drill-holes (BUSY167 and BUSY180) were drilled in the gap between central and western Veta Sur (Figure 1). Both intersected multiple high grade auriferous veins (for example, BUSY167 2.25 m (at) 43.76 g/t gold, 113 g/t silver and BUSY180 2.10 m (at) 21.31 g/t gold and 31 g/t silver) within broader intervals (for example, BUSY167 25.45 m (at) 12.02 g/t gold, 57.4 g/t silver) of medium grade gold exhibiting moderate base metal contents.
Four drill-holes (BUSY186, BUSY181, BUSY165 and BUSY185: Figures 1 and 2) targeted the central part of Veta Sur. Each intersected multiple high grade auriferous veins (some with high silver contents) commonly within broader mineralized intervals. These intercepts (Table 1) demonstrate strong grade continuity of vein sets along strike and dip. BUSY186 extended high grade gold mineralization down to elevations below 1250m RL in central Veta Sur (Figure 2). Each hole also displayed several intersections with Stage II overprints, significantly extending the area of influence of this high grade mineralization.
BUSY192 was drilled to clarify the extensions of the Veta Sur system to the northeast, under the Diatreme Fault system. Mineralised intercepts in this drill-hole occur over a substantial depth range down to 1300m RL (Figure 2). High grade vein sets (from 305.08m down-hole, 3.24 m (at) 32.70 g/t gold, 350.6 g/t silver and from 427.75 m, 4.25 m (at) 24.12 g/t, 57.9 g/t silver) correlate well with those in BUSY150, BUSY90 and BUSY82 also drilled in northeast Veta Sur, extending these veins both laterally & vertically.
BUSY164 expanded the Veta Sur system to the southwest (Figure 1), encountering several auriferous base metal-rich veins (Table 1) in this area.
Several drill-holes added significantly to the emerging silver story in the Veta Sur system. BUSY 164 intersected a set of veins with high Ag/Au in southern Veta Sur, including 3.0 m (at) 517 g/t silver. BUSY167 (0.4 m (at) 11 g/t gold, 350 g/t silver) and BUSY186 (0.7 m (at) 21.01 g/t gold, 549 g/t silver) intersected good silver grades on the southern side of Veta Sur (Figure 1) confirming a high silver vein set through this area. BUSY181 (1 m (at) 6.51 g/t Au, 340 g/t silver), BUSY165 (1.10 m (at) 3.90 g/t gold, 1424 g/t silver) and BUSY185 (0.70 m (at) 1.38 g/t gold, 473 g/t silver) all encountered multiple intervals of high grade silver on the northern side of Veta Sur, adding to extents of silver-rich veins in this area.
Yaragua (Figure 1)
Significant new drill intercepts in the Yaragua system are tabulated below:
Drilling in the Yaragua area has focused on and been successful in:
BUSY178 and BUSY182 (Figure 1) both intersected multiple auriferous veins (see Table 2 for vein correlations) within broader mineralized intervals that correlate well between holes. The drill intercepts are up to 100metres west of those encountered in previous drilling and demonstrate the continuity of the Yaragua system at relatively high elevations and also deep below the Diatreme Fault.
BUUY58 and BUUY59 (Figure 1) drilled to north in west-central Yaragua also intersected multiple vein sets (see Table 2 for vein correlations) and broader intervals of breccias-hosted mineralization, some intercepts being deeper than previous drilling in this area. These drill holes further demonstrate the lateral and vertical continuity of the southerly and central vein sets in west-central Yaragua.
BUUS006 and BUS007, short holes drilled to clarify the distribution of mineralization in the walls of underground openings, both intersected veins north of and footwall to the San Antonio vein.
Yaragua South (Figure 1)
Significant new intercepts from drill-holes collared in the Yaragua South area are tabulated below:
Drilling from the Yaragua South area has focused on and been successful in:
BUSY183 and BUSY176 each intersected multiple vein sets (Table 3) of the southern Yaragua system extending these veins to depths substantially below underground openings in eastern Yaragua (Figure 1).
Both drill-holes, at shallower depths, resulted in the discovery of several new auriferous vein sets in the Yaragua South area. The distribution of these intercepts and surface geochemical anomalies may indicate that these vein sets have substantial strike and depth extents.
BUSY187 intersected high grade silver veins (including 1.40 m (at) 5.99 g/t gold, 1210 g/t silver) south of the main Murcielagos veins, confirming substantial strike and depth extents of this silver-rich southerly system.
