Diamond deposits have long been recognised as requiring specific attention with respect to Mineral Resource estimation practices. Nowhere is this more apparent than in the estimation of Mineral Resources on alluvial and marine deposits. The 2016 SAMREC Code has acknowledged these issues, as well as those more often associated with smaller deposits.
The SAMREC Code has a detailed diamond-specific section comprising Clauses 60-72; a diamond-specific section to Table 1 (Section 11). In addition, a Guideline Document has been prepared which provides the methodologies and definitions of the relevant terms that should be considered in the preparation of reports on Diamond Exploration Targets, Diamond Resources and/or Diamond Reserves. It also provides a guide table of contents to assist with the compilation of Competent Persons Reports (CPR’s).
