Continental Gold Drills 10.8m @ 43.97 g/t Gold and 54 g/t Silver in New Deep High Grade Subzone at Veta Sur and 4.0m @ 135.88 g/t Gold and 114 g/t Silver at Yaragua, Buritica Project
TORONTO, ONTARIO -- (Marketwire) -- 03/22/11 -- Continental Gold Limited ('Continental' or the 'Company') (TSX: CNL) is pleased to announce results from fifteen diamond drill-holes from the Company's ongoing program at its Buritica Project in Antioquia, Colombia. Over 51,000 metres of diamond drilling have been completed on the property to date and eight drills are currently working on a 60,000-metre surface and underground drill program for 2011.Highlights
- Significant new drilling intercepts on the Veta Sur system include:
10.8m @ 43.97 g/t Au and 54 g/t Ag including
3.44m @ 123.08 g/t Au and 131 g/t Ag in drill-hole BUSY-146,
10.7m @ 17.17 g/t Au and 214 g/t Ag in BUSY-140 and
1.25m @ 364.49 g/t Au and 154 g/t Ag in BUSY-142
Drill-hole BUSY-146 includes a newly discovered high grade subzone in the deepest part of the Veta Sur system drilled to date. BUSY-142 further delineated a very high grade steeply plunging shoot in the 'core' of the Veta Sur system which remains open to depth in high gold grades.
- Significant intercepts from drilling at the Yaragua system include:
4.0m @ 135.88 g/t Au with 114 g/t Ag including
1.2m @ 449.90 g/t Au and 373 g/t Ag in drill-hole BUSY-120 and
3.25m @ 22.79 g/t Au with 21 g/t Ag in BUSY-125
These and other results for the Yaragua system continue to demonstrate the continuity of potentially economic grade-thicknesses of several of the Yaragua vein sets over a substantial depth range and strike length.
Details
Continental's 100%-owned 18,000-hectare Buritica project has several known areas of high-grade vein mineralization. The two most extensively explored of these areas are the Yaragua System which has been drill-tested along 550 metres of strike and 600 vertical metres, and the Veta Sur system which has been intersected along 500 metres of strike and 375 vertical metres. Both systems are characterized by multiple veins and both remain open at depth.
Veta Sur System
Table 1 presents summary results for seven new drill-holes on the Veta Sur system of veins. The holes confirm the continuity of multiple precious metal veins in the central 120 metres of the known 500-metre strike extent of the system and extend the vertical range of high grade mineralization to 375 vertical metres.
BUSY-146 demonstrates a new high grade (10.8m @ 43.97 g/t Au and 54 g/t Ag) sub-zone at 1425-metre elevation, almost 300 metres below the shallowest bonanza grade gold intercepts in Veta Sur and 200 metres below this system's very high grade 'core' (Figure 1). An even deeper (1339-metre elevation) high-grade intercept in BUSY-146 also exhibits Stage-II style mineralization characteristics (low base metals, free gold & significant silver values), extending the vertical range over which Stage II mineralization overprint has been observed. Between these two intervals, at 1352-metre elevation, high grade Stage-I style mineralization exhibits pyrrhotite in addition to pyrite and also high Ag/Au and is interpreted to reflect deposition from more reduced hydrothermal fluids in the vicinity of Cretaceous carbonaceous metasediments abutting the Buritica intermediate intrusions. BUSY-146 also demonstrates that the Veta Sur system is open to depth in high grade gold.
Bonanza grade gold intercepts in BUSY-142 (Table 1) extend the region of very high grade intercepts (greater than 100 g/t Au), in the central upper part of Veta Sur (Figure 1). This high grade 'core' of the system, which exhibits strong Stage II-style mineralization overprints, is interpreted to represent a steeply plunging shoot with a length of more than 100 metres, open to depth and towards the surface.
BUSY-136 intersected two intervals of high Ag/Au (including 1.57m @ 6.13 g/t Au and 327.2 g/t Ag and 0.9m @ 66.17 g/t Au and 526.4 g/t Ag) on the northern side of Veta Sur system, as well as possible new vein to the southeast. BUSY-106, also drilled to the south but lost before target depth, intersected high Ag/Au intervals including 1.5m @ 233 g/t silver. On the southern side of Veta Sur, BUSY 146 intersected high Ag/Au intervals including 0.4m @ 64.33 g/t Au and 1195 g/t Ag. Further drilling into both sides of the Veta Sur corridor is expected to confirm high grade gold-silver veins.
A 19.2m intercept at 3.75 g/t gold with 19 g/t silver in BUSY-104 is the first indication of potentially bulk underground minable, lower grade material in the Veta Sur system. This style of mineralization has been well-documented at Yaragua with numerous thick intercepts at similar grade in the breccia.

Yaragua System
The results of eight new Yaragua drill-holes are summarized in Table 2. These drill-holes covered about 100 metres strike length in the central part of the known 550 metres of strike of the multi-vein Yaragua corridor and included a step-out drilled in the eastern part of the system (Figure 2). All drill-holes intersected several vein sets exhibiting potentially economic grade-thicknesses.
BUUY-54 was an underground hole drilled to the north crossing much of the width of and penetrating deeply into the Yaragua corridor. It cut several veins at potentially economic grades and widths including the San Antonio-FW-Vein A packages at elevations below 1200 metres, some of the deepest intersections drilled to date in the Yaragua system. Substantial widths of the potentially bulk minable Yaragua breccias were encountered higher in the drill-hole.
BUSY-110 showed good grade- thicknesses in the San Antonio-FW-Vein A packages, some 50 metres east of and at 300-350 metres higher elevations than in BUUY-54.
BUSY-120 intersected 4.0m @ 135.88 g/t gold, 114 g/t silver and 4.1% zinc in the San Antonio vein extending a very high grade segment of this vein set outlined by underground sampling (Ref. to the Company's March 3, 2011 news release). BUSY-125 intersected good grades and widths in the San Antonio vein set at RL's well above the underground sampling.
In the sparsely drilled eastern part of the Yaragua system, BUSY-119 cut the Murcielagos vein exhibiting gold grades comparable to those historically mined in this area. Further to the north and deeper this drill-hole also intersected a silver-rich vein and several other as- yet-uncorrelated auriferous veins.

Other areas
Two holes were drilled to the north into the Yaragua North area. Both holes encountered extensive intercepts of low grade gold (averaging about 0.1 g/t and with high Ag/Au) which are highly anomalous in copper and variably anomalous in molybdenum, antimony and tellurium. Both BUSY-114 and BUSY-139 each exhibited several metre-plus intersections of 1-3 g/t gold and up to 35 g/t silver within the lower grade envelopes. Further work is needed to evaluate the significance of this mineralization.
BUSY-141 was drilled primarily for geotechnical purposes near the path of a proposed underground access decline and encountered no significant mineralization.
