The Fortune Minerals facility, to be located east of Langham, about 35 kilometres from Saskatoon, would process ore concentrate from a mine in the Northwest Territories.
A director with Fortune, Rick Schryer, says there have been three main concerns raised by residents.
The biggest is the use of water from the Dalmeny aquifer, while the others are fears the aquifer will be contaminated from leaking brine or other chemicals.
Schryer says whether the plant gets built depends on government approval and the mine in the Northwest Territories which will send ore concentrate for processing.
He adds they don't want to build the plant before the mine is done because then it will just sit there idle.
Construction on the processing facility could start as soon as late next year.
