Structure of the proposed mining area at Ohai

This report cover the structure, as so far revealed by drilling of the area in which it is proposed to begin a new mine, west of the present Star Mine. There are enough drillholes in the area to enable strusture contours to be drawn on the roof of No.1 seam. Only three drillholes have unquestionably penetrated to No.2. Seam but structural contours on this horizon should parallel those on No.1 with a slightly lesser dip, as the interval between the seams increases to the east. Several faults have been proposed to account for irregularities in the contours, threem of them having to throw of 100 feet or more.
