Yukon's Occupational Health and Safety authorities have laid dozens of charges against the Tagish Lake Gold Corporation.
They allege the company supervisors violated safety rules and ignored stop work orders imposed by inspectors.
The charges stem from inspections of the Wheaton Valley property, about 80 kilometres south of Whitehorse, last summer. Officials say equipment on site was unsafe, and workers were poorly trained.
Mine supervisors Bill Lewkoski and Michael Greasley are charged along with the corporation.
Tagish Lake Gold was taken over by a Chinese-owned company, New Pacific Metals, in 2010. Exploration and drilling work has focused around the old Skookum Gold mine which operated briefly in the mid-1980s.
A court date to answer to the safety violations is scheduled for September.
