All-in sustaining costs and all-in costs. The Guidance Note on Non-GAAP Metrics all-in sustaining costs and all-in costs was first issued in 2013. In light of new accounting standards and to support further consistency of application, the The World Gold Council has published an updated Guidance Note, which includes incremental enhancements.
Feb 01, 2014 The mean relative Milling cost for open pit mines 48.9 4.6 was larger than both the underground operations 34.1 8.3 and those incorporating both underground and open pit 39.3 6.6. Median values shown in Table 4 suggest that the Milling values were less sensitive to outliers than the mean Mining cost values.
