Geostatistics: Black Box Magic or Skilled Procedure?

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.

Specialty Commodity Sector

Specialty Commodity Sector

In the specialty commodity sector, it is the geology and mineralogy of the raw material source that ultimately provide the consumer with a secure, consistent supply of a processed mineral or metal product meeting the required specifications. M.Plan International – Micon’s joint venture with Anzaplan GmbH – offers a fully integrated suite of services to the specialty commodity sector for project development studies and due diligence assessment.

Cut-off Grades for Mineral Resource Reporting

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”. The implications of this for the selection of a cut-off grade are discussed in this article by Micon’s V.P. Geology, Terry Hennessey.

Continuity in Mineral Resource Estimation

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

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.
