Willow leaves (all variants of Salix pulchra) and A-, B-, and C-horizon soils were sampled near 2 mining prospects suspected to be high in Cd.
The A-, B-, and C-horizon soil and willow leaf samples were collected from 21 sites combined.
Work in 2004 included 117 organic soil samples, 108 C-horizon soil samples, 75 stream sediment passed concentrate samples and 19 kilometers of VLF-EM geophysical surveying.
The drill hole also intersected the Western C-horizon which proved to be wider than anticipated.
