Mineral Resources of Terrace Area, Coast District, British Columbia INTRODUCTION In 1935 the writer commenced the examination of the mineral deposits in Terrace district, British Columbia. Deposits containing gold, copper, lead, zinc, and silver are numerous in the area and have been briefly described from time to time in the Annual Reports of the Minister of Mines of British Columbia. Reconnaissance geological work has been done by Leach, McConnell, Hanson, and Marshall for the Geological Survey, Canada, and their reports are listed under Bibliography. It has been the writer’s endeavour to supplement the work already done by detailed examination of the deposits and of the geology in their immediate vicinity. Geological maps of those properties on which con- siderable development work has been done are presented in this report. A number of assay returns from the individual deposits are also given as a guide to the grade of ore. The report is designed to assist the prospector and to attract the attention of mining companies to the economic possibil- ities of the area. Terrace is 70 miles in a straight line east-northeast of Prince Rupert and occupies a lower central position in the Terrace map-area which lies between latitudes 54° 20’ and 55° 00’ and longitudes 128° 00’ and 129° 00’. The area measures 40 miles from east to west and 46 miles from north to south. Skeena river flows in a south to southwest direction across the area and the Canadian National railway follows its valley. A good motor road extends from Terrace to Usk and is being continued eastward to con- nect with the Hazelton highway at Cedarvale. Kitsumgallum lake 20 miles north of Terrace, and Lakelse lake 9 miles south of Terrace are both accessible by motor car and boats are available on both lakes. A road extends north from Rosswood at the north end of Kitsumgallum lake to Cedar River crossing, a distance of 10 miles, and a good trail continues northwest from there to Nass river. The area was too large to permit the examination of all mining pros- pects during the 1935 season, so that only the central and western part of the area was covered. The deposits examined include those in Kitsum- gallum Lake section, those in the vicinity of Terrace, those on Thornhill and Kleanza mountains, and those in the vicinity of Usk. The properties are all easy of access as good pack-horse trails have been built up the mountains to them from the nearest roads. Placer gold was recovered from Kleanza, Chimdemash, Fiddler, Lorne, Douglas, and Phillips creeks, in Terrace area, as early as 1884, and placer miners still work the gravels in these streams from time to time. Mineral claims were first staked in 1893 in the vicinity of Usk, the Emma, Four Aces, and Toulon being the first on which there is a record of early work having been done. In 1910 there were about two hundred claims staked in the vicinity of Usk on deposits containing gold, silver, and copper. A few years later, minerals containing gold, silver, copper, lead, zinc, molybdenum, and tungsten were found in deposits on Thornhill
