Drill results from the Macuchi property in Peru have enabled Northfield Minerals (TSE) to confirm a bulk-minable gold zone in the Mercedes mine area.
Significant results were returned from surface holes MER-20 and 21 and underground hole MER-25. In addition, channel sampling by Northfield on the Level 1 crosscut, situated 45 metres south and 30 metres below MER-19, returned 2.53 grams gold per tonne and 0.44% copper over a true width of 22 metres. A higher-grade section, measuring 16 metres wide, averaged 3.21 grams gold and 0.54% copper.
The drilling and underground sampling confirmed a major bulk-minable zone of gold mineralization in the Mercedes mine area, which extends at least 400 metres along strike and is open along strike in both directions, as well as downdip. The sixth level is being rehabilitated to provide access to drill-test the downdip potential. This level is 300 metres below the mountain top and is readily accessible.
Underground drilling is under way in the Esperanza area, 1.5 km north of the Mercedes mine, on Level 6. The first hole, MER-28, is drill-testing a gold zone identified by Cotopaxi in the 1940s. This zone extends for 400 metres and has a width of up to 16 metres.
A second surface drill is being moved onto the property to drill-test the Minchoa 1 and 3 areas, 3 km south of the Mercedes mine. Recent trench sampling results from highly oxidized and leached rock have been encouraging.
At Minchoa 1, a trench across the mineralized zone returned 1 gram gold across 23 metres (true thickness) with a higher-grade section of 1.45 grams across 10 metres. Two trenches at Minchoa 3 returned 1.6 grams gold over 12 metres, including 7 metres grading 2.4 grams and 4 metres grading 1.5 grams.
The mineralized zone at Minchoa 3 has been traced on surface for more than 500 metres.
