The property of this Company consists of 240 acres of mining lands situatedin the south-eastern part of the township of Tisdale. The ore consists of large masses of quartz and cliist, frequently alternatelybanded and much mixed. The presence of quartz seems to be a necessary accom-paniment of the gold values, though it is rather along the small contracts of thequartz and schist that the gold occurs, than in the quartz itself. The ore is, how-ever, so mixed that very little sorting can be done, and the whole mass is sent tothe mill if the average is of milling grade.
