ELKO, Nev. (AP) — A federal investigations report reveals that a double-fatality accident at a mine east of Elko was caused by unenforced policies, lack of communication and ineffective traffic rules.

The Elko Daily Press reported Monday that two mine employees died last October after a loaded 340-ton (345-metric ton) haul truck struck a van at SSR Mining Inc.'s Marigold Mine near Valmy.

The report by the Mine Safety and Health Administration states that the van operator failed to make radio contact with the mobile equipment operator and parked in the haul truck's blind spot.

The federal agency cited the mining company for a violation of the Code of Regulations regarding traffic control.

The company has since updated its policies and procedures, and added information about blind spots awareness and communication in its new training materials.
