' The sites for the four exploratory core holes were picked to maximize <br />• the information oa the deeper coal seams. These locations are spotted oa <br />the attached mine map.* All four holes vere continuously cored using eater <br />as circulating fluid. <br />Each of these yells established a static eater level of from 14 to 20 <br />feet below the collar as soon ae drilling passed that depth. Thin static <br />level did not change during drilling. Ia no instance vat there a floe of <br />eater to surface (collar) during or after drilling operations, although each <br />hole had gas (methane) floes which broke through the crater column to surface. <br />Based on these results ve can conclude with a high degree of confidence [bat <br />there are no artisian eater floes is the normal Hesavezde section below the <br />'E' seam. <br />I <br />As stated earlier, each hole vas continuously cored from the base of the <br />• 'E' seam to total depth, i. e. a fee feet into the Rollins Sand on WSC f5, /7, <br />and i8. and to the bottom of the Lover 'B' seam on IiSC /6. The sedimentary <br />sequences between coal seams in each hole reflected a depositional environment <br />of from lover deltaic to marginal marine. Glaucoaitic sands gave evidence of <br />minor transgression - regression activity. The sedimmtary rocks present vere <br />a typical inter-coal sequence of sand, siltstone and shale with some mudstone <br />intezlayers and inclusions, and, rarely, very thin limestones. These elastic <br />rocks vere invariably fine grained. clastic sizes greater than fine sand vere <br />not encountered. The sandstones generally vere titelq cemented with calcareous, <br />argillaeeous or organic cemencs. <br />*(Navks Nest Mine Map - small scale with i7SC O5, /6, l7 and 08, and nee test hole <br />• spotted.] <br />2.09-25b <br />
