QA/QC Audits of the Primary SGS West Wyalong Laboratory are carried out on an approximately quarterly basis and for the Umpire ALS Orange Laboratory approximately six-monthly.
Any issues are noted and agreed remedial actions assigned and dated for completion.
Numerous internal audits of the database and systems have been undertaken by site geologists and company technical groups from North Ltd, Homestake, Barrick and Evolution. External
audits were conducted in 2003 by RMI and QCS Ltd. and in 2011 and 2014 review and validation was conducted by RPA. MiningOne conducted a review of the Cowal Database in 2016
as part of the peer review process for the Stage H Feasibility Study. Recent audits have found no significant issues with data management systems or data quality.
