First, he indicates a bias occurs when estimating average grade for large blocks by combination of direct point grade estimates. Second, he proposes an “improved” indirect point estimate to minimize the problem of inconsistent point estimates (negative or huge point grade estimates) frequently observed with the indirect method. He concludes that the improved indirect method should be used for point estimation rather than the direct method even in the presence of positive grade-thickness correlation. Marcotte and Boucher (2001) results clearly indicate the indirect point grade estimates are more accurate... You do not currently have access to this article.
