passing gradually into a massive eruptive-looking variety. Interbedded with it are bands of dark shales, limestone, serpentines, and in one place a.red magnesite; at New Hogem granites come in, exposed to Old Hogem, and a couple of miles along the trail to Vital Creek they are replaced again by the green and dark schists, which are exposed until the valley of Takla Lake is reached, when Cretaceous conglomerates and sandstones again occur. The green and dark shales constitute the gold- bearing rocks of the district. Indications of coal have been found in various places and lignite reported from the upper part of Duck Creek. In 1909 the Kildare Company, which held fourteen hydraulic leases on Slate Creek, worked twenty men and cleaned up about $10,000. In 1913 this company took in machinery by pack-train and in 1914 located a pay-streak, the portions passed through the sluice-boxes yielding $30 a cubic yard. The Omineca Gold Mines, Limited, took up fourteen leases on Quartz and Vital Creeks in 1913, and G. H. Knowlton and associates, of Vancouver, twenty-one leases on Silver Creek and Omineca River, and began a road from Takla Lake to Old Hogem to facilitate taking in dredging machinery. Value of the ground tested by drills was reported better than Go cents a yard. Work was suspended during the war and has not since been resumed on any scale. The report of the Resident Engineer of the Department of Mines for 1921 said: β€œ Another placer-field which attracted considerable attention at one time β€˜is what is known as the Omineca; this consists of the Manson and Ingenika sections of Omineca Mining Division, Certain rich creeks in these sections were worked many years ago and intermittent mining was carried on until recent years. With the decline of gold-mining during the war years and the lack of prospectors in the hills, the district was virtually abandoned and now there is but a small production from it. β€œ There is in this part of Omineca Mining Division a very large area to be thoroughly prospected for placer gold. The country lying at the headwaters of the Skeena, Stikine, and Finlay Rivers should yet yield some rich placer-gold creeks, and it would not be surprising if the next great placer stampede was to this section. Around the old placer- workings of the Manson and Ingenika sections there is undoubtedly much low-grade ground which would pay to work by modern methods, but the handicap of lack of transportation has so far prevented much develop- ment of this nature. At the present time the means of access to these sections is by pack-trail from Hazelton or Fort St. James, and distance from the railway is over 200 miles. It is obvious that only the richest of placer-gravels could be worked with any chance of success. The field, however, is a promising one for testing the possibilities for large- scale hydraulicking and dredging, as, if sufficient pay-ground was found, the transportation could be materially improved by the construction of a wagon-road.” To the present prospecting has been almost entirely confined to placer gold. Leads of copper ores and galena have been discovered close Twenty-four.
