depth from 14 to 546 m.

Database
The collection and verification of data has been detailed in prior sections of the report. For the 2007 resource estimate, there were 340 drillhole collars in the database with a total drilled length of 55,326 m (Figure 17.1). Drill depths range from a minimum of 14 m to a maximum depth of 546 m. All holes are diamond core holes. Drilling was primarily conducted in two directions: Approximately 35% of the holes were drilled in an east-west orientation and approximately 50% of the holes were drilled in a north-south (315°) or south-east (135°) orientation. The remaining holes have various orientations including vertical. Due to the different drillhole orientations, the drillhole spacing is highly variable. Some portions of the WRZ area are drilled on a grid spacing of closer than 20 m; however, the majority of the better mineralized areas are drilled on a nominal grid spacing varying between 30 m and 50 m.
The database comprises 38,023 individual analyses for gold, ranging from 0.001 to 5,840 g/t Au, and 35,624 analyses for silver, ranging from 0.05 to 3,100 g/t Ag. Note that these include results originally defined as negative values, meaning “below detection limit”, which were set to half of the detection limit for estimation. The database also contains analyses for lead, zinc, copper, arsenic and manganese; however, these attributes were not incorporated into the resource estimate.
