UNFC–2009 – Purpose of Resource Classification David MacDonald Houston 21 November 2013
A Couple of Anecdotes • A famous company misrepresents its reserves with collusion of the board of directors • Application of revised rules significantly alters management’s previous estimate • Risk mitigation not in-place results in revision of field reserves • Management found to be trading shares prior to release of revised reserves estimates Institute of Mining and Metallurgy London, 1911

Principles for Resource Classification • Project based • Project management • Classification of total volume • Clear boundaries between categories • Discovered • Commercial (economic and social license)
Resources are measured against … Uncertainty well defined (with high confidence) Economic to extract (commercially feasible) Technically feasible to extract Sustainable Mining and the UNFC, India, 29-30 October 2013

Sustainable Development for All • Definition must include entire resource base • Maintain competitive advantage • Recognise the total potential • Over-conservatism may lead to lost opportunity • Uncertainty analysis must identify the components • Technical • Project • Commerciality and Social License UNFC-2009 with its focus on economic viability, technical feasibility and uncertainty is well placed to meet all of these needs.
