The square and rectangle cells can be designed around vertical holes drilled in flat/layered deposits ( Fig. 10.5 ). The reserve is estimated by multiplying total surface area, average thickness, and average Sp. Gr. The grade estimate is estimated by thickness weighted average grade of all drill holes. Figure 10.5.
