Colombian Mines (TSX-V:CMJ) said Wednesday that all core holes drilled to date at its Yarumalito property in Colombia encountered "significant" intervals of surface and near surface gold mineralization.
The most recent results include 95.5 metres, grading 0.70g/t gold in hole YAR-14, and 151 metres, grading 0.64g/t gold in hole YAR-24, from the bulk tonnage porphyry targets being explored in the current drilling program.
The company said that hole YAR-24 also intersected high grade, structurally controlled mineralization on strike, with the high grade gold intercept recently reported for hole YAR-11 that assayed 33.75g/t gold over 1.8 metres.
YAR-24 had a cumulative intercept length of 5.9 metres, grading 8.7g/t gold, consisting of three separate mineralized structures with individual structures to 2.1 metres, grading 12.67g/t gold.
Hole 24 was drilled in the La Escuela target, while hole 14 was designed as an initial scout hole in the western portion of the previously untested Balastreras porphyry target.
"The company's most recent drilling at Yarumalito clearly confirms and expands near surface porphyry and porphyry-related mineralization in both the La Escuela and Balastreras targets. Based on the most recent interpretation of existing data, the Balastreras and La Escuela targets merge in the near surface, forming a single large porphyry system approximately 2,500 metres east-west with a variable width averaging 1,400 metres," the company said in a statement.
The company continued to say that the latest geochemical sampling indicates that high grade intercepts in holes YAR-03, 11 and 24 are part of a highly mineralized, structurally controlled "vein" zone, which appears to be more than 3,000 metres long in an east-northeast direction, striking across the Yarumalito porphyry target area, between the La Escuela and Balastreras zones.
