Despite the current extremely competitive labour market in the resources sector, 90 positions were recruited to join Pilbara Minerals’ workforce during the March Quarter.

As a result of this recruitment campaign, the Company’s employee numbers increased by 15% in the March Quarter and 121% over the last twelve months with a total of 339 employees as at 31 March 2022"
