Chinese men accused of running illegal gold mine in Congo
Around 60 Chinese nationals were at the site and officials detained 17 who appeared to be in charge.
VANCOUVER, BRITISH COLUMBIA–(Marketwire – Aug. 31, 2011) – Nevsun Resources Ltd. (TSX:NSU)(NYSE Amex:NSU) is pleased to report the assays from the forty-three diamond drill holes at the hanging wall copper zone within its Bisha mining license in Eritrea. The hanging wall copper zone is immediately west of the Bisha Main deposit and partially within the current open pit limit but it is not included in the current resource or reserve estimate for Bisha.
Highlights
Select Results Include:
A two phase drill program was designed to define the extent and continuity of the previously identified copper mineralization located within the hanging wall of the Bisha deposit. Phase 1 of the program was completed in March 2011. The results were positive, and have provided valuable information on the extent and nature of the mineralization. Phase 2, focused on infilling the mineralization in order to calculate resources, will start in mid-September. Nevsun views the hanging wall mineralization as a potential source of supplemental feed for the processing plant at Bisha.
Detailed Phase 1 assay results are in the attached schedule together with a map of the hole locations. Assays from holes B-463, B-464, B-465 and B-466 reported on the map are still pending as drilling was delayed due to mine operations in the area.
Drill hole B-395 intersected a 30m lens of supergene copper mineralization grading 8.55% Cu that was not previously identified. The lens appears to be an extension of the northwest lens of Bisha that was faulted off and not previously identified. Hole B-395 was lost within the mineralized zone so B-396 was drilled 3m to the south to test the full depth extent of the lens, yielding 22m of 4.47% Cu. Holes B-463 and B-464 were then drilled 50m to the west. B-463 drilled over top of the lens but B-464 intersected 30m of supergene enriched massive sulphide. Assays for this hole are still pending.
The Company also completed a 16,000 meter diamond drill program on the Bisha Main deposit. The objective was to infill drill the inferred resources in the Bisha Main resource with the goal of upgrading the resources to the indicated category. Results of this drill program are expected over Q3 and Q4 2011 with a second reserve re-statement targeted for Q4 2011.
