Gold Mining Corp. (TSX VENTURE:BZA) announces an update to the underground
drilling program at its 100% owned high-grade Copperstone gold project in
Arizona.
D-Zone Underground Core Drilling
Underground core drilling continues at the D-Zone. Objectives of the program
are conversion of known indicated and inferred resources into measured
resources and reserves, and mine planning. A total of 56 holes have been
drilled with a combined length of 5,440 metres. Approximately 1,700 metres in
20 planned holes remain to be drilled in the program, which is about 75%
complete and has a budget for the entire program of approximately US$1 million.
The most significant intercepts in the new assay results include a 10.5 metre
zone grading 36.4 g/t gold, including 3.2 metres of 89.0 g/t gold, in drill
hole number DU5-56; a 3.9 metre zone grading 47.1 g/t gold in drill hole number
DU4-51; and a 5.7 metre zone grading 1.6 g/t gold and 6.8 percent copper in
drill hole number DU4-53.
As previously reported, these D-Zone drill intercepts are oblique to the
mineralized Copperstone fault; true thicknesses of the D-Zone range up to 7
metres thick. DU5-56 has a true thickness of 4.2 metres based on cross
sectional analysis. The following table is a summary of assay results for this
group of underground holes from the D-Zone drilling program:
