Canadian Potash Developments 1965 - Introduction

In world-wide mining circles countries become known by the principal minerals they produce. The production of iron, copper, phosphate and sulphur in the United-States-has-been particularly significant and has provided the base for aggressive developments in heavy industry, agriculture and chemicals. Mention diamonds and gold-and you will think--South Africa; silver-Mexico; nickel and asbestos--Canada. The main purpose of this paper is to point out that potash mast be added to the list of minerals by which Canada is known in the mining World. The potash deposits of western Canada must be classed as a major world source of chemical fertilizer raw material. We believe that they are both the largest and the richest of all known deposits in the world. The most knowledgeable people in the industry avoid making estimates of reserves because even where the arithmetic is correct the total is so large that it appears to be ridiculous. In 1957 Marion Goudie made a carefully qualified estimate of 6 billion tons of recoverable potash above 3,500 ft, and grading 25 per cent K20 or better. This figure can now be increased by the amounts available through solution mining. No one has bothered to estimate how much this is because it is so large that the actual amount is not significant.
