AbstractThis report presents the geochemical data, quality assurance and quality control (QA/QC) results of the re-analysis of lake sediment samples collected from north-central Saskatchewan (NTS 074-A, B, G and H). The original lake survey was conducted in 1986 and the re-analysis in 2021. Original survey results are presented in OF1359. A total of 1,290 lake sediment samples were re-analyzed, covering an area of 17,000 km2, averaging a density of 1 sample per 13 km2. Samples were measured for 65 elements via modified aqua-regia - ICP-MS and 35 elements via INA analysis. To ensure high quality data, the geochemical data was evaluated for contamination, accuracy, precision and fitness-for-purpose. QA/QC results have identified a number of elements to be monitored carefully for future analyses. Overall, the data are of good quality.
Summary(Plain Language Summary, not published)
Under the Government of Canada's Geo-Mapping for Energy and Minerals (GEM) program, this study presents quality assurance and quality control results from re-analyzed lake sediment samples located in north-central Saskatchewan (NTS 074-A, B, G and H). The results demonstrate that the geochemical data is accurate, precise, fit-for-purpose and relatively free from contamination.
