John T. Boyd Company's assignment for the Dunn-Nokota Methanol feasibility study was to determine the quality of the Dunn Center lignite seams for the area studies, both on an in-place and run-of-mine basis. Previous available quality data was reviewed, absence of required data noted, and a new drilling program designed to complete the data base. Additional core samples were taken in March, April, and October of 1981, analyzed and the quality weight-averaged with previous data to develop average field quality. A geological reserve study was completed in 1980 by Boyd Company which incorporated information from 747 rotary holes and quality from 52 cores holes. Of these core holes, 32 have influence in the area of interest used for this study. The laboratory analysis from the 32 core holes within the area of interest are summarized in this subsection. The data are reported on in-place dry, in-place as-received, and in-place equilibrium moisture bases and adjusted for out-of-seam dilution to the run-of-mine, equilibrium moisture basis. Laboratory analysis provides the basic data to compute field quality Table 2-1 presents the previous quality data on an in-place, dry basis by seam.
