The block model is created using geostatistics and the geological data gathered through drilling of the prospective ore zone. The block model is essentially a set of specifically sized quotblocksquot in the shape of the mineralized orebody. Although the blocks all have the same size, the characteristics of each block differ. The grade, density, rock type and confidence are all unique to each block within the entire block model. An example of a block model is shown on the right. Once the block model has been developed and ana

1.1 PHASES OF A MINING PROJECT Home ELAW

There are different phases of a mining project, beginning with mineral ore exploration and ending with the post closure period. What follows are the typical phases of a proposed mining project. Each phase of mining is associated with different sets of environmental impacts. 1.1.1 Exploration A mining project can only commence with knowledge of the extent and value of the mineral ore deposit

Ore Reserve Estimation Method

Ore reserve estimates are based upon the results of exploration and development and analyses of the samples derived therefrom. Unless a deposit is fully developed (and even then to a lesser degree), certain assumptions have to be made regarding the continuity and grade of ore between exposed faces or drill holes that have been sampled. In making these assumptions, the engineer must interpret

MINERAL EXPLORATION AND MINE DEVELOPMENT

Ore is the rock from which an element ultimately will be extracted. The weight percent (or grade) of the desired element in the rock varies considerably from one mineral to another at operating minesmuch less than 1% by weight for gold, more than 60% by weight for some iron ore mines. Ore usually is transformed into concentrate at the mine site. Concentrate is an upgraded material. For
