CIM Estimation of Mineral Resources & Mineral Reserves Best Practice Guidelines - Rock Hosted Diamonds (2008)


CIM MRMR Committee

Developed by the CIM Sub-Committee, these guidelines are an addition to Guidelines Specific to Particular Commodities which are appended to the CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines. Diamonds are produced commercially from intrusive rock, consisting of kimberlite and lamproite, and from alluvial and marine placer deposits. These guidelines apply to rock deposits; the term ""diamonds"" herein refers to natural diamonds; ""diamond deposits"" refers to diamonds hosted in kimberlite and lamproite rocks; and ""diamonds"" and ""stones"" are interchangeable.The CIM Best Practices General Guidelines for other commodities are also applicable to diamond deposits, however, because of diamond's distinguishing aspects, additional guidelines are appropriate as published in the CIM Guidelines for the Reporting of Diamond Exploration Results and these Best Practice Guidelines for estimating Mineral Resources and Mineral Reserves (MRMR).
