Calibre Mining has announced further drilling results from its Riscos de Oro, which is an epithermal gold and silver project located in Northeast Nicaragua’s Borosi concession.
The company has obtained the final drilling results including more than 1,500 soil samples from a regional soil survey campaign conducted at Riscos during 2011. These drilling results demonstrate more than 3 km strike length of anomalous arsenic and gold concurrent with the Riscos de Oro deposit trend. Calibre has discovered further anomalies, which is expanding a strike length of additional 4 km to the southwest direction. It has shown up the gold, arsenic, lead and zinc anomalous regions at the Central zone and in the El Paraiso region.
As the soil survey was conducted successfully, a trenching campaign has been initiated by Calibre along the inferred vein system trend in order to additionally examine the discovered arsenic and gold anomalies. The results from the trenching and soil sampling program will be jointly utilized to drill the reconnaissance holes along the formation of 7 km length, which houses the Riscos de Oro. The company has moved a second drilling rig to the location and is conducting the resource definition drilling at Riscos de Oro. The plan of the drill campaign is to additionally outline the fine epithermal gold and silver layer stockwork mineralization, which returned 288.25 g/t silver, 10.25 g/t gold over 5.4 m in RD11-010 and 211.80 g/t silver, 7.69 g/t gold over 10.6 m in RD11-012 during the former drill program.
