The Exploration and Development of Canadian Uranium Deposits

Introduction The development of uranium deposits is a relatively recent phase of mining in Canada. To date, the only producer of uranium ores on a commercial scale has been the Port Radium mine on Great Bear lake, N.W.T. However, with.-in the past few years intensive prospecting has been carried on throughout Canada and many occurrences of uranium-bearing minerals have been discovered. Eldorado has been active in the search for and the exploration of uranium deposits in Canada for a longer period than any other company and has, therefore, accumulated a considerable fund of information, especially about occurrences in Saskatchewan and in the Northwest Territories along the western fringe of the Precambrian Shield. The Company has also had experience in the underground operation, and in the mining, of uranium ores at Port Radium. During the past year or so many requests have been received from the prospecting and mining fraternity for information and guidance regarding the development of the many new uranium discoveries that have been made in Canada. Assistance by Eldorado is freely given whenever possible and this paper is presented to supplement the private discussions and to provide as wide a distribution as possible of the data acquired by Eldorado.
