The silver and pitchblende ores at Great Bear Lake have attracted wide attention. Great Bear Lake is on the Arctic Circle, east of the Mackenzie River, and the deposits are at Echo Bay on the east side of the lake.

Since the original find in May, 1930, the geology of the region and of the mineral deposits have been described by a number of geologists and engineers. A list of these papers is given in the accompanying bibliography.

After spending two months in 1931 examining the mineral deposits and making a reconnaissance of the areal geology, Kidd published a brief account1 of the geology and mineralization at the Eldorado mine, the most important deposit in the district. In 1932, he spent six months making further field studies of the mineral occurrences and conducting a broad reconnaissance over 3000 square miles of geologically unknown territory. The results of this work . . .
