Piedmont Lithium Ltd (ASX:PLL) CEO Keith Phillips tells Proactive the lithium explorer has received the Section 404 Permit under the Clean Water Act from the US Army Corps of Engineers for its lithium project in North Carolina.

Phillips says this landmark achievement follows a fair, albeit rigorous process, that the company managed to get done within a year. Philips adds that in the next year investors should expect chemical plant permitting along with a fully bankable feasibility study.
