"Tables and results have been compiled using estimated costs of mining and cut-offs of $60 per tonne for bulk mining and $90 per tonne for selective mining. True widths are estimated to represent between 75% to 85% of core length for holes SD-11-37A, 11-42 and 11-45; and, 90% for hole SD-11-41.

Mineralization contained within the South Corridor typically consists of massive sulphide lenses or veins, surrounded by stringer networks and hosted within highly silicified limestone and skarn. Drilling shows that mineralization becomes increasingly zinc-rich at depth, with an increasing copper content. This appears to conform to the general trends of metal zonation observed for the Velardena District. "
