International giant mining firm BHP Billiton Ltd (ASX: BHP) said on Friday that it is set to remit up to $C90 billion or $A90.07 billion in royalties and taxes to the various government branches of Canada and bulk of the payment would be allocated to the government of Saskatchewan.

BHP Billiton said that its Jansen potash project in the country should be in operation for a number of decades and Saskatchewan is set to receive up to 65 percent of the projected government earnings from the project.

The company added that an additional yearly income of at least $C280 million should be realised by the federal and provincial authorities in Canada from the project, which would be sourced from employees and companies that were poised to set up activities in the area during the course of the project's construction stage.

Saskatchewan would be seeing some 4,200 available jobs during the construction stage of the Jansen project, according to BHP, while an average of 2,900 full-time jobs would be spawned by the time the project is in full swing of operation.

While the company conceded that some revenues may decline during the initial stage of the project, as reported by the Conference Board of Canada, it called into attention "that in future years when Jansen starts to operate and such deductions have been utilised, the reverse occurs and the province receives more taxes than it would have otherwise."

BHP Billiton pointed out that the deferred payments cited by the report would eventually be cancelled out by the inflows of corporate income and sales taxes set to be collected from parties tasked to establish Saskatchewan's new potash mine.

The company's Jansen site is set to achieve full production capacity by 2021 and BHP is aiming to augment the in-between gaps by tossing a $US40 billion or $A40.8 billion hostile takeover proposal for Potash Corporation of Saskatchewan, in hopes that a successful bid would lead to some 20 percent control on the global potash industry.

As of 1044 AEDT on Friday, BHP Billiton shares were trading lower by 14 cents at $40.81.
