MULLAN, Idaho-- An official report has been released in the deadly collapse at the Lucky Friday Mine last April.
53 year old Larry Marek was killed April 15th, when he was wetting a muck pile and a 90-foot long section of ground fell and struck him.
The Mine Safety and Health Administration released its findings on the incident Friday.
In its report, the MSHA says the Hecla Mining Company did not take proper precautions at the Lucky Friday Mine.
The overall finding in the report says Hecla didn't have the right policies and procedures in place for safe mining.
The report claims Hecla management failed to design, install and maintain a support system to control the ground where miners worked.
It also says Hecla failed to make sure supervisors tested the ground conditions where the collapse happened.
Hecla Mining Company has since adjusted procedures and policies to meet MSHA's citations.
Hecla Mine says it will continue to investigate its policies to ensure safety during all mining procedures.
The company's president says he wants to make sure an accident like this never happens again.
Just two weeks ago another miner was killed underground at the lucky Friday mine.
Brandon Gray was standing on a pile of rocks that began sinking. Gray then became trapped underneath them.
An investigation into that accident is ongoing.
