RIO Tinto has declared it is sitting on a big potash deposit in Saskatchewan in the same basin where its rival BHP Billiton is spending $US3.8 billion ($4.2bn) just to be ready to mine the fertiliser ingredient when global food demand warrants it.
In its annual report, Rio described the KP405 potash discovery as the eighth “tier-one” discovery in the past decade by its exploration group. “Drilling results indicate encouraging potash grade and thickness,” Rio said.
“Higher nutritional standards, population growth and limited arable land make potash a critical factor in maintaining global food security.” Rio’s Russian partner, Acron, has been more animated, saying there is the potential for a long-life, low-cost mine at the “massive” KP405 deposit.
BHP chief Andrew Mackenzie describes potash as a potential “fifth pillar” of BHP’s commodities business, indicating the potential he thinks the company has in Saskatchewan’s Elk Point Basin.
BHP last year approved a $US2.6bn spend to gain access to the deposit, bringing total approved spending to $US3.8bn before it has made a definite decision to mine.
