16.13 BLOCK MODEL

A percent model was set up in Gemcom to accurately represent the volume and tonnage of each individual kimberlite unit within a block. As a result, kimberlite unit boundaries were properly represented by the percent model’s capacity to measure infinitely variable inclusion percentages. Each kimberlite unit was represented by a separate block model folder containing rock type, density, percent, class, grade and value models.

A block model size of 30 m x 30 m x 15 m was selected for modelling based on LDD sample spacing. The block model extents were extended far enough beyond the kimberlite unit limits to accommodate a pit shell.

16.14 ESTIMATION & CLASSIFICATION

Mineral resources were classified in accordance with guidelines established by the Canadian Institute of Mining, Metallurgy and Petroleum, 2005:

  • Inferred Mineral Resource

“An ‘Inferred Mineral Resource’ is that part of a mineral resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drillholes.”

  • Indicated Mineral Resource

“An ‘Indicated Mineral Resource’ is that part of a mineral resource for which quantity, grade or quality, densities, shape and physical characteristics, can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drillholes that are spaced closely enough for geological and grade continuity to be reasonably assumed.”

  • Measured Mineral Resource

“A ‘Measured Mineral Resource’ is that part of a mineral resource for which quantity, grade or quality, densities, shape, and physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable
