Assay Results from the
In-Fill Drill Program at the Bisha Gold/VMS
Deposit, Eritrea
ASSAY RESULTS FROM THE
IN-FILL DRILL PROGRAM AT THE BISHA GOLD/VMS
DEPOSIT, ERITREA
June 20, 2005
As part of the
Bisha feasibility study a reserve statement
estimate will be required and, in order to
confirm continuity of mineralization and
verify variography, Nevsun has drilled
several parts of the deposit on sections
12.5 meters apart. Two areas were selected
by AMEC for detailed drilling, one in the
southern part of the deposit where less
continuity had been indicated and one in the
northern part of the deposit. The final
feasibility study is scheduled for
completion in the first quarter of 2006.
Assay results
from the southern block of infill drilling
have been received. Coupled with results
from past drilling as well as holes B-316 to
B-319 that were drilled earlier in the 2005
program and reported in a press release of
March 29, 2005, it is interpreted that the
grade of mineralization is at least equal to
and likely better than the October 2004
resource statement indicates. The continuity
of mineralization has been confirmed by this
additional work.
