Would you mind providing a link to your source, @HarleyRider? The information I can find suggests that it's a 2mpta copper smelter you're referring to, and that production isn't schedule until 2021.
This article, dated Jan 2017, has the ground-breaking ceremony scheduled for end of 2017, or early 2018 at the latest, with smelter operations expected in 2021.
This article, dated May 2017, has a budget deadline of June 2018, with smelter operations to commence late 2021.
Just wanted some clarification, because at a glance your post suggests a manganese smelter.
