About Jason Whillier
I am a Mechanical Engineer working in the Mining and Construction Industry in Africa and America with a strong passion for designing and building complex structures. I have hands-on experience in the construction, design, and maintenance of mining equipment and structures, including the installation and repair of SAG and Ball Mills, conveyors, thickeners, and pump systems, flotation and solvent extraction systems. I have successfully supported and executed capital projects, provided site supervision, and delivered engineering support for large-scale mineral processing operationsI thoroughly enjoy the challenges of bringing decommissioned mines back into operations as much as building new greenfield projects. I believe mining is a large part of the foundation of any economy and I work hard towards bringing numerous mines around the world into operation in a way that is safe and sustainable.
