El Centenario
|
Target Minerals:
Gold & Silver
Size:
2,325 Ha.
Location:
The El Centenario concession is located in the central Dominican Republic, approximately 77 km northwest of the capital of Santo Domingo.
Property Geology and Mineralization:
It was discovered by grassroots prospecting by Battle Mountain/Canyon in 1991. The work completed on the concession to date has outlined a low sulphidation epithermal gold system.
Past exploration between 1990 and 1997 consisted of extensive channel sampling, detailed mapping, soil sampling, mangetometer and IP/resistivity surveys and 6,563.8 metres of diamond drilling. This work outlined a zone of low sulphidation epithermal gold mineralization in an area of 250 x 200 metres and extending to a depth of approximately 50 m. The mineralized zone is extensively silicified in the form of banded, drusy quartz veins, stockworks and breccias.
Gold mineralization is typically fine-grained, dominantly in quartz veins and breccia zones, particularly with base metal sulphide rich sections. Grades in excess of 300 g/t Gold have been recorded in the veins with average grades in the order of 5-10 g/t over several metres across the vein and breccia zones and for several tens of metres along dominant structural trends. One of the highest grade drill intersections ran 14.28 g/t Gold over 18 meters. Numerous significant intersections began directly at the surface including 8.61 g/t Gold over 24 meters from 1-24 meters depth. Silver values are subordinate to gold, with an overall gold to silver ratio of about 20 to 1. The zone remains open to the north and has not been fully delineated to depth. A preliminary calculation in 1994 of the mineralized zone estimated a potential resource of 220,000 ounces of gold.
Exploration:
In January 2004 a joint venture with GoldQuest Mining Corp. on the El Centenario project in the Dominican Republic was announced. GoldQuest Mining Corp. has to spend US$1.0 million over three years to earn a 60% interest in the project.
