Colibri Resource has declared that it is developing the Ramard silver project, which is situated in State of Sonora, Mexico. A detailed exploration program, including a soil geochemical and systematic rock sampling, geologic mapping and three dimensional induced polarization (IP) geophysical surveys, was recently completed by the company.
Many IP resistivity and chargeability anomalies were discovered by the company’s geophysical survey. These anomalies are related to surface geochemical copper-lead-silver-zinc anomalies. The La Bronca zone has one such anomaly below it. The company has planned to commence a 2,000 m diamond drill program at the La Bronca zone on 5 March. The company delayed the drilling program in order to complete analysis of work that was performed during the previous months and to target the comprehensive sampling and mapping in regions that contain surface geochemical anomalies. Besides the La Bronca zone, the company identified that many surface anomalies comprise strongly anomalous metal values over the study region, measuring 2,000 ha, inside the Ramard claim.
A huge IP chargeability anomaly was exposed by the 3D IP geophysical survey. The anomaly corresponds with the appearance of the mineralization and alteration surface at the La Bronca zone. The thickness and length of the chargeability high is 400 m and 600 m, respectively. This anomaly continues to a depth of a minimum of 300 m. The percussion drilling and surface sampling programs that were conducted during 2006, 2007, and 2011 have shown the existence of skarn-type mineralization, containing lead, silver and zinc, in previous silver producing region. Colibri is delighted with the surface exploration results and is expecting to commence the drilling program.
