The reanalysis of archived stream sediment samples by inductively coupled plasma mass spectrometry (ICP-MS) is recognized as a cost-effective means of obtaining new and improved geochemical information. This technique provides a significant upgrade from the previous atomic absorption spectrometry (AAS) method routinely used for surveys conducted before 1999 particularly for base metal determinations. The use of ICP-MS will not only provide a wide range of new analytical information at improved detection levels, but also provide greater data compatibility with analytical methods being employed for new geochemical survey work. Recognizing the advantages associated with this type of initiative, this project involves the recovery and analyses of approximately 2500 sediment pulps from the Terrace map areas (NTS 103I and J).
The work is expected to stimulate mineral exploration by presenting new geochemical data for an area that is considered to have a good potential for future discoveries of precious and base metal deposits such as those found at the Edye Pass and M & K Mines. Results will also significantly enhance existing geochemical data and complement other geoscience information available in the region. Potential long-term economic benefits can be expected from increased mineral exploration and deposit discoveries.
