Pros
Real industrial experience
You’ll work in a large mining and industrial environment, not just theory from university. That experience is valuable on your CV.
Exposure to heavy equipment and maintenance
Since you’ll be in the maintenance department, you may learn about pumps, crushers, conveyors, hydraulic systems, generators, and other industrial machinery used in mining operations.
Good networking opportunities
You’ll meet engineers, technicians, supervisors, and managers. Those connections can help with future jobs.
Cons
Can be physically and mentally tiring
Mining environments are demanding. Long hours, noise, heat, dust, and standing for long periods can be exhausting.
You may start with basic tasks
Interns are not always given exciting engineering work immediately. Sometimes you observe more than you actually design or decide things.
