Our Team in Focus ✨📖 Hear from Shade and Layton, first-year apprentices at our Kanowna Belle Operations, as they share what it’s like being part of the onsite community. Shade “People onsite look out for each other. You come in to learn a trade, but you also become part of a team pretty quickly. “Starting at the same time as Layton, we’ve been able to learn alongside each other and grow in our roles together. Having that support makes a real difference to how you show up and the work you do.” Layton “There’s a strong sense of community onsite. Working with supportive and knowledgeable people really helps to keep building your skills and confidence. “I enjoy being hands-on, getting involved in the job and learning how things work. Having someone like Shade there from the start just adds to that, you’re learning, contributing and building connections at the same time.” Interested in exploring early career opportunities with Northern Star?
