Geostatistics: Black Box Magic or Skilled Procedure?
Geostatistics is more than just a black-box or button-pushing exercise. It is a process involving a suitable collection of data and geological information, a detailed analysis of this data, an understanding of suitable methods for estimation and their inherent assumptions, and a systematic and comprehensive validation of the output model. Tools such as software packages are not magic wands that mysteriously produce models that fit the characteristics of the natural phenomenon. A sensible geostatistical estimate takes time, understanding, experience and skill to produce.
Can I Use Historic Assay Data in My Resource Estimate?
Can use be made of old or historic assay data in a current mineral resource estimate?

Cut-off Grades for Mineral Resource Reporting
Under the CIM Standards on Mineral Resources and Reserves – Definitions and Guidelines, a mineral resource must be in “such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction”.

Continuity in Mineral Resource Estimation
In the second of a series of articles discussing best practice, we focus on the importance of continuity within a mineral resource. The first article covered the classification of resources. Continuity lies at the heart of that discussion and, from Micon’s point of view, is one of the most important but one of the most frequently overlooked issues when conducting mineral resource estimates.
Classification of Mineral Resource Estimates
In the first of a series of articles on best practice DOs and DON’Ts, Bill Lewis, senior geologist with Micon in Toronto, highlights the need to tread carefully when classifying Mineral Resources. The classification of Mineral Resources is an important factor in the analysis of risk on advanced mining projects, and implementing best practices in this area can improve the probability of a successful mine development.
