Cerro Negro Gold Project
Bajo Negro
The Bajo Negro vein, identified in 2006, displayed only sporadic surface outcrop extending over 100m in a north-westerly direction. Trenching and surface sampling resulted in a range of gold grades from anomalous to 3 g/t gold and increased the known strike length to 350m.
The confirmation of the Bajo Negro vein discovery, located 13 kilometres east of the Eureka West veins and 2 kilometres southwest of the Vein Zone deposit, was announced on May 19, 2009.
The latest holes have outlined the southeastern part of a high-grade (>100 gram. meters gold) ore shoot surrounded by mineralization >50 gram-meters, which remains open along strike and to depth. The top of the mineralization (as defined by the 5 gram meter contour) occurs at 50 to 100m depth, and is likely to have been influenced by the paleowater table.
Encouragingly, this would suggest that the hydrothermal system is intact and has undergone little or no erosion. Barren silicified outcrops, 150m northwest of current drilling (see Figure 1), are interpreted as remnants of a silica cap deposited above the paleowater table. Aeromagnetic lineaments (Figure 1) suggest that continuation of the vein below these outcrops is a strong possibility.
