Grade and geological continuity in high-nugget effect gold–quartz reefs: implications for resource estimation and reporting

摘要: AbstractHigh-nugget effect gold-quartz reefs are one of the most challenging styles mineralisation to evaluate and exploit. The estimation mineral resources, subsequent ore reserves, forms a critical base for exploitation. understanding application grade geological continuity issues during is importance. Most reporting codes make specific references issues. Within high nugget environment, confidence in tonnage estimate variable depending upon continuity, though it usually higher than estimate. Estimation problematic as result erratic low gold values gold-bearing domains. Detailed interpretation supported by 3D modelling produce either 'conceptual' or 'visual' models critical. inherent risk associated with resources reserves classification can be reduced ...
