ASSIBEY-BONSU, W. et al. Production reconciliation of a multivariate uniform conditioning technique for mineral resource modelling of a porphyry copper gold deposit. J. S. Afr. Inst. Min. Metall. [online]. 2014, vol.114, n.3, pp.iv-v. ISSN 2411-9717.
The paper provides a brief review of a multivariate uniform conditioning and a localized multivariate uniform conditioning (LMUC) technique, and presents a production reconciliation case study based on a porphyry copper-gold deposit in Peru. The reconciliation study compares the long-term LMUC mineral resources model (typical of new mining projects, which are invariably based on drilling data on a relatively large grid) to the corresponding production blast-hole grade control model, as well as the final plant production.
