Mineralization Comments

Jul 22, 2008 (D Draper) - Highest zinc assays were returned from a 5-metre zone of alteration containing a quartz-carbonate breccia and quartz veining: 4800 ppm over 0.6m; 1100 ppm over 0.7m; 2500 ppm over 1.0m. The lowest zinc assay listed was obtained from a section with the most sulphide mineralization noted, including sphalerite; this section also assayed 328 ppm Mo. (T-2510)
