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”.

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.

Continuing the theme of ‘Best Practice’, Micon’s senior geologist and environmental engineer David Makepeace, B.Sc., MMSA, describes the key features of an Environmental Baseline Study.
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.
Why Mines Fail
