Vacuum on the tailing lysimeters was verified on January 31t', no water was present for sampling
and subsequent analysis.
Depths to water were collected for the tailing impoundment main embankment piezometers and
the West Pit and tailings embankment monitoring wells were collected on January 31~'. January
tailing impoundment piezometer measurements identified these installations were either dry or
contained less than 12 inches of water as illustrated in Table 2. Tables 1 and 2 below identify the
