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.

Concepts:

· Sampling process and error

· Accuracy and precision

· Bias and error

· Data management

· Statistical measures.

Measuring accuracy:

· Standards

· Dealing with multiple standards

· Bias measurement

· Defining an unacceptable result

· What to do if an unacceptable result is obtained.

Measuring precision:

· Duplicate samples

· Measures of precision

· Defining an acceptable precision outcome

· What to do if the precision achieved is not acceptable.

Measuring contamination:

· Blanks

· What to do if contamination is detected.

Other areas of QAQC:

· Particle size analysis

· Survey data

· Density 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.
