"These women reflect the enormous value that diversity and inclusion provide to our sector," CME chief executive Paul Everingham said.

"Some are currently in leadership positions and some will progress to those types of roles. But each is already an outstanding role model for the tens of thousands of women who work each day on mining and resources operations around WA, and many more who might be considering careers in our sector.

"I'm very proud to work in a sector that has a genuine commitment to promoting and achieving equality, inclusivity and diversity in its workforce.

"By recognising and celebrating not just our award winners but also the finalists in each category, we can hopefully further shine the spotlight on the extremely wide variety of jobs, career pathways and leadership opportunities available to women in our sector."
