This 2-day course covers the QAQC life cycle: 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 an holistic view of QAQC and emphasise the importance of having a rigorous and comprehensive system.  We also emphasise learning the key techniques by building the analysis tools in 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 you 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 CRMs, 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

Feedback from attendees:

• Thank you so much for sharing your knowledge and not making us feel silly for our questions! 
• Great course. The course has given me a good overview of QAQC and given me plenty of topics to further build upon. 
• Very useful course! Thank you
