The Saskatchewan potash deposit in Canada is the largest potash reserve in the earth, which is recognized by its great scale, thick potash members, high grade resource and very few impurities. The ‘Sino-potash’ project owned by Zhongchuan Mining is the first potash project in Saskatchewan run by Chinese enterprise. The authors investigated into the project's 5 drilling wells completed between 2008 and 2009 using sedimentology, mineralogy and geochemistry. It is shown that mineralization in the region is similar to that of currently operating potash mines of Saskatchewan. Thick sylvite members deposited in a relatively shallow depth spread continuously in the whole region, though the deposition depth is slightly deeper than those of the operating potash mines of Saskatchewan. The result tells that the middle-Devonian Saskatchewan potash deposit forms steadily and continuously, which is mainly composed of sylvite, with small amount of carnallite. The deposit dips slightly in the northeast-southwest direction from outcrops in Manitoba to the south Saskatchewan and reaches as deep as 2750 m, suggesting a great potential of resource in the area which was not defined as a potash mining area historically.
