Mariana Minerals is looking for a highly motivated Senior Mine Planner to lead strategic mine planning, opportunity evaluation, and long-range optimization across the company’s portfolio of mining projects. This role is responsible for defining how mines are evaluated, designed, sequenced, and optimized—from early-stage concept evaluation through life-of-mine planning.
In this role, you will own long-range mine planning and multi-pit optimization efforts, setting the technical and analytical foundation for capital allocation, project prioritization, and development strategy. You will establish company-wide standards and best practices for short-, medium-, and long-term mine planning, ensuring consistency, rigor, and decision-quality across all assets.
This is a senior technical leadership role that sits at the intersection of geology, mine engineering, economics, and corporate strategy. You will influence what projects get built, how they are sequenced, and how value is maximized over time.
