Lake Sediment/Water Surveys

In parts of British Columbia where topography is subdued, surface drainage is poor and there is an abundance of lakes, lake sediment and water surveys are a valuable exploration tool for delineating regional geochemical patterns and detecting anomalous metal concentrations related to mineral occurrences.

Samples are collected by boat or a float-equiped helicopter using a Hornbrook-type torpedo sampler. Lake bottom sediments are dried, screened to 80 mesh (0.170mm) and the -80 mesh sediments are analized for elements by atomic absorption spectrometry (AAS), inductively coupled plasma emission spectroscopy (ICP) and instrumental neutron activation (INA).
