The Lawton City Council and two economic entities approve a new Westwin Elements agreement on Tuesday.
The approval means the project can begin.
A construction crew already is on site, staging the area for construction of a pilot plant to refine cobalt and nickel. Preliminary work could begin in days.
The first of three city boards has approved a new redevelopment agreement for the Westwin project. Members of the Lawton Economic Development Authority voted unanimously to approve the amended and restated development agreement that will allow construction of a $14 to $16 million pilot plant to refine cobalt and nickel.
