Excerpt from Proceedings of the Royal Society of Victoria, Vol. 16: Part I, Issued September, 1902, Containing Papers Read Before the Society During the Months of December, 1902, March, April, May, June, July, 1903 Adverting, however, to the occurrences of gold, that at Mount Elmo will now be considered. The rocks amongst which it is found are quartzites with mica and andalusite schists, and these are associated with holocrystalline rocks, some of which are undoubted metamorphosed, whilst there are others about which some reserve must be made, but which will probably prove also to be of metamorphic character, and which appear to have been intrusions that already existed in the area prior to the period at. Which the change from shales to schists took place. Mount Elmo lies about three miles south east by east of the trigonometrical survey station of Mount Towanga, and the field is reached from Eskdale by one of the new roads of the Mines Department following the western or main branch of the Little Snowy Creek. The mines are upon several lines of reef, a considerable distance apart, two of which are at Mount Elmo, where they dip with and follow the ancient bedding planes of the country. The dip is 65 degrees east and the strike is about 10 degrees west of true north. The reefs at Mount Elmo have not yet been traced for a distance of more than about 1% miles, and are, as far as prospected, cut off completely by the bands or masses of the holocrystalline rocks just mentioned. The author was not able to visit the mass at the southern end of the line of reef, but at the northern end, lying between the Little Snowy Creek and the mountain spur containing the reef outcrops themselves, the band is variable in character. One mass that he saw was a tour maline rock with felspars and muscovite, whilst another showed upon slicing, felspar, muscovite and biotite, some quartz exhibit ing much strain structure and containing small fibrous inclusions, probably sillimanite, light brown hornblende and tremolite. The top of the mountain, somewhat to the eastward of the line of reef, is of greisen, a mass of which appears to lie parallel to the schists, but there was not an opportunity to trace out its extent.
