Sunridge Gold has reported assay results from the 21 diamond drill holes at the Debarwa copper-zinc-gold deposit, which is present in Asmara Project, Eritrea.
Almost all drill holes have expanded the depth of the major mineralization from 150 to 200 meters from the surface at Debarwa deposit. The assays, which is planned to be completed in April 2011 will be used for updating the resource estimate and the ongoing feasibility study at Debarwa. So far, 59 drill holes have been completed in the ongoing drill program. Still, assay results for 24 diamond drill holes are awaited.
Sunridge is focusing much on shallow parts of the Debarwa deposit, Gold Oxide and Copper Supergene Zones in particular. These new deeper holes indicate high-grades of copper, zinc and gold in the main mineralization zone.
The company intersects 4.71% copper, 0.95 g/t gold over 6.00 meters in hole DEB-149, 1.32% copper, 10.51% zinc and 4.87 g/t gold over 7.60 meters in DEB-146. It also cuts 1.15% copper, 3.2% zinc and 4.07 g/t gold over 8.10 meters in DEB-157.
The feasibility study at Debarwa deposit will take up the flotation-based standalone process plant to recover the base and precious metals. The company will study a variety of mining operations over a mine of around 9 years. In addition, the study will examine the option for direct shipping to explore high-grade copper mineralization to improve economics of the Debarwa deposit. It is expected that the report will be completed in the third quarter of 2011.
