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.
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.
When is something “economically mineable” for the purpose of reporting a mineral reserve? Beyond requiring the use of certain reporting codes, NI 43-101 does not specify a methodology for the estimation of mineral resources or reserves.
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.
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.
Following his presentation to the MINEX 2015 Conference in Moscow, we asked Stanley Bartlett, P.Geo., Managing Director of Micon’s UK subsidiary, to recap the main points of his speech with examples taken from his professional experience.
