The top executive with one of the biggest mining companies in the world won't speculate on the future of the Jansen potash mine.

Speaking in Regina Tuesday night, BHP Billiton's Chief Executive of Non-Ferrous, Andrew MacKenzie focused on potash supply.

"I just want to leave you with a very simple message, nothing is running out and I mean nothing in both Saskatchewan and western Australia," he said.

He also highlighted the growing demand for potash around the world due to population growth.

In the speech MacKenzie said work continues at the Jansen mine saying two shafts are currently being built.

"We'll reach a kilometre down to touch the Jansen ore body and they will be capable of ultimately supporting a mine," he explained.

MacKenzie turned down a request for an interview about the Jansen project.

Industry analysts have speculated the Jansen project in Saskatchewan could be pushed back until next year.
