Piedmont is committed to progressive reclamation throughout the life of our operations. For our Carolina Lithium project, production of lithium hydroxide will continue at the site long after mining for spodumene ore is complete. However, we plan to start reclamation from our mining activities as soon as practically possible to restore and prepare the site for post- operational use.

Of the four quarries included in our proposed Carolina Lithium project plans, we expect that three will be backfilled with excavated rock, which will then be covered. Native vegetation can be planted on the slopes of these rock piles as we build them. The quarry located near our production facility can be filled with water and remain as part of our manufacturing site.

Piedmont is responsible for these reclamation activities, and we plan to pay for them. In accordance with North Carolina mining permit requirements, we will likely post a surety bond to provide financial assurance to the community that reclamation will occur. The State of North Carolina determines the amount of the bond and will not release funds until we have proven that all reclamation requirements have been met.

In the future, we want the Carolina Lithium site to be put to good use. When the time comes, we would like input from relevant stakeholders on potential, post-operational uses. The site could be a place for parks, trails, greenways, industrial uses, business uses, solar development – or a combination of any of these.
