Petina’s hands-on geological expertise spans mining exploration and operations through to closure. Her role is to provide holistic strategies facilitating the fulfillment of optimal closure and mine waste management processes. She also provides solutions for challenges clients encounter in active day-to-day mining operations.

With many clients located in mining towns, it’s important for mining companies to actively implement appropriate closure practices that meet environmental obligations, maintain their social licence to operate, and satisfy local communities. Working with our closure and geosciences team, Petina has been fortunate to work with Gold Fields Australia at their St. Ives Gold Mine project for many years—a technically challenging operation that spans a large, diverse area. She’s delivered and received regulatory approval for several mine closure plans and technical studies across a variety of disciplines for the operations.

Away from her work providing mine closure strategies, Petina enjoys her garden, playing hockey, and travelling locally and internationally with her family.
