[1] Assets under construction are not being depreciated as they are not in the condition necessary to be capable of being operated in the manner intended by management.

Capitalized expenditures for the Battery Material Demonstration Plant under construction are presented net of grants of $4,109 for the year ended December 31, 2022 ($5,483 in 2021).

During the year ended December 31, 2021, the Company bought back a 1.8% NSR on the Matawinie property for $1,800 that is included in Mine under construction.
