NEW YORK–(BUSINESS WIRE)–$PLL #Lithium–Piedmont Lithium Limited (“Piedmont” or “Company”) is pleased to announce that it has awarded the definitive feasibility study (“DFS”) of its planned spodumene concentrate (“SC6”) operations in North Carolina to a combined team including Primero Group (“Primero”) and Marshall Miller & Associates (“Marshall Miller”).
