Exploration QA/QC - field to lab to review

Maximising value while minimising cost

How many standards should be submitted? What about Blanks? How do you take a representative Duplicate? Is a replicate a duplicate? Should you try to maximise or minimise variability in a duplicate? Is this CRM matrix matched? Are soil duplicates a waste of money?

QA/QC is an integral part of exploration which is potentially done poorly. This one day workshop will address three components of the QA/QC process: how samples are collected in the field, what happens when samples get to the lab and how to interpret QC data. Case histories, exercises and videos will be used to illustrate concepts. Participants are invited to bring their own data.
