Sayona Publishes Positive Pre-Feasibility for North American Lithium Mine Restart

Piedmont Lithium Ltd of Belmont, NC reports that its partner, Sayona Mining Ltd of Australia, has recently published a pre-feasibility study for the restart of spodumene concentrate operations at the North American Lithium (NAL) project in Quebec. The NAL pre-feasibility contemplates average annual production of approximately 168,000 tonnes/year of 6% spodumene concentrate over a mine life of 27 years.

The NAL study highlights estimated competitive cash operating costs and an estimated capital cost for the mine and concentrator restart of approximately US$80 million.

Piedmont and Sayona acquired the previously-producing NAL operations in August, 2021. Following the positive results of NAL’s study, the partners expect plan to proceed with full capital expenditure authorization. According to Sanyona’s study results, operations could recommence in the first half of 2023.

Piedmont owns a 25% project interest in the NAL and Authier projects via its equity stake in Sayona Quebec as well as its equity interest of approximately 16.5% in Sayona Mining. Piedmont will now begin to explore marketing options for its share of spodumene concentrate contemplated in its off-take agreement with Sayona, which provides Piedmont with the right to purchase the greater of 50% of production or 114,000 tonnes/year from the NAL project.

Patick Brindle, Piedmont’s COO, commented, “The proposed restart at NAL in the first half of 2023 represents the next step in helping Piedmont achieve its vision of becoming the leading lithium hydroxide producer in North America.”
