Distinguish the services
Identify drilling, excavation, haulage, processing support, maintenance and technical work. State whether crews work underground, on the surface or at separate facilities. Include occasional activities and subcontractors, since a broad description can miss the operations most important to the underwriting review.
Identify property interests
Separate machinery owned by the contractor from operator equipment and material being handled. Ask how customer property, valuables or processed materials are treated when relevant to the contract. A contractors equipment policy should not be assumed to insure the mine’s stock, product or entire production system.
Address remote and specialized logistics
Discuss parts availability, recovery costs, access and transportation of large equipment. Review professional and pollution exposures where the contractor designs, tests or treats materials. The submission should explain the insured entity’s actual responsibilities without implying that the company insures or controls the entire mine.
Illustrative review scenario
A hard rock mine hires a contractor to operate a processing component and handle material supplied by the owner. The agreement makes the contractor responsible for damage to that material as well as machinery. Review those interests separately, including property-in-custody and product-related restrictions. Equipment insurance for the contractor’s machines does not establish protection for every item passing through the process. Does the contract place valuable customer material in your custody during processing or transport? Review that property interest explicitly, because coverage for machinery and coverage for material are different questions.
