Lynda Bloom, M.Sc., P.Geo.
President, Analytical Solutions Ltd.
It has been almost 25 years since Bre-X inspired the implementation of technical reports worldwide. The reporting requirements triggered the use of quality control (QC) materials (blanks and certified reference materials) and quality improvements at commercial laboratories.
Many aspects of monitoring QC have been automated and commercial CRMs are readily available. But questions remain about insertion rates, the selection of CRMs, defining acceptance values for CRMs and how to use duplicate data. There is a lack of clarity about the role of core duplicates, when non-commodity elements in a multi-element package should be monitored and how to report precision.
Quality control is a system to manage risks and we should ask if we are managing the risks appropriately.
After earning a M.Sc. at Queen's University in Geological Sciences, Lynda has had 45 years of experience with all aspects of exploration geochemistry. She is recognized as a world-expert on assay methods and has traveled extensively worldwide to review sampling and analytical procedures. Her pragmatic approach to problem-solving has earned her the respect of a broad range of clients.
Lynda was awarded the PDAC Distinguished Service Award in 2020 for her dedicated volunteer work in the mining industry including many advisory boards, mentoring and leadership. Since 1989, she has held numerous executive roles with public mining companies.
