Ainsworth Mining Camp

"The Ainsworth mining camp is on the west side of Kootenay lake; British Columbia; 14 miles south of the town of Kaslo. It is in one of the oldest mining districts in central British Columbia; for mining started there in 1888. Its principal production was between 1905 and 1920. Activity since then has been sporadic. According to available records; some 222; 000 tons of ore had been produced from the camp up to 1942.GENERAL GEOLOGY Bedrock in the district consists of a succession of quartzite, quartz-mica schist, hornblende schist, and limestone of Late Precambrian, Carboniferous, and Triassic age. Most of the hornblende schists are of volcanic origin but some formed from related intrusions. The Nelson granodiorite batholith of Jurassic age borders the camp on the west. There is also a series of basic dykes of much later age."
