QAQC: Getting the most out of your QC data
This two-day course covers the QAQC lifecycle: from planning the types and frequencies of QAQC data to be collected; the mechanics of collecting, transporting and submitting the samples; analysing to reveal systematic and trending errors; deciding what is and what isn’t a failure; and to making the changes in the resource database. We take a holistic view of QAQC and emphasise the importance of having a rigorous and comprehensive system. We emphasise learning the key techniques by building the analysis tools in Microsoft Excel and by analysing and commenting on real-life QAQC data.

· The geoscience database.
During the course, attendees will:
· Understand the key issues associated with and tests for precision, accuracy, contamination, and bias
· Learn the optimum insertion rates for the various types of QAQC test for your commodity and system
· Cover best practice associated with certified reference materials, blanks, duplicates, umpire laboratories, and other types of QAQC
· Appreciate the best tools for analysing QAQC data and how to construct the relevant charts and statistics
· Determine anomalies and failures, how to fix them, and how to ensure that it doesn’t recur
· Understand how assay labs work and how to interact with and inspect them.
