After more than a year, Hecla’s Lucky Friday Mine in Mullan, ID has reopened and has began producing again.
Regulators from the U.S. Mine Safety and Health Administration (MSHA) ordered Hecla to close the mine after two miners were killed and seven injured in three separate events in 2011. The closure order came after a wall collapsed near the main silver shaft in December 2011, injuring seven miners. Two miners were killed in earlier accidents that year.
Officials of the Hecla said the safety issues have bee resolved and clearance from regulators to resume operations has been granted.
“This is a great day for Hecla,” company CEO Phillips Baker said at a Feb. 19 news conference in downtown Spokane, WA. He cited roughly $60 million in safety improvements and other mine investments that resolved issues identified by federal regulators, the Spokesman Review reported.
“We believe the Lucky Friday Mine is in better condition than at any time in its history,” Baker said.
The company began mining silver and other metals from the mile-deep main shaft last week. Baker said Hecla has about 300 workers employed again. About 90 percent of them were working at the Lucky Friday before silver mine operations halted in January 2012.
Company officials made a series of focused safety upgrades, he said. They include:
- Adding several new safety-focused managers and trainers.
- Helping develop safer mining practices, particularly by having miners use a team approach to identify concerns.
- Investing $2.3 million in new mining equipment, including new telehandlers and scissor lifts. Those machines allow miners to remove ore from upper walls while working inside protective cages or baskets, said Larry Radford, the company vice president for operations.
- Installing 61,000 rock bolts and 20 miles of chain-link fence throughout the mine to improve stability.
The Mullan mine, which has been in operation for seven decades, typically produces about 93 t (3 million ozpy) of silver.
At current silver prices of around 96 cents/g ($30/oz), the 12-month impact felt by Hecla not producing silver comes to roughly $90 million in lost revenue.
Baker said the company expects to hit full production by the second half of this year. He estimated the Lucky Friday will produce 62 t (2 million oz) of silver this year.
The mine’s reopening is a major economic boost to the Silver Valley and North Idaho. Area officials have been eager to see the mine reopen, as Hecla miners are paid more than workers in manufacturing and construction.
In his remarks Tuesday, Baker said Hecla spent roughly $30 million on the rehabilitation of the main silver shaft and $26.2 million for capital projects that are part of ongoing expansion and upgrades to mine operations.
Baker also said the improvements were undertaken in part to resolve a “potential pattern of violations” notice sent to Hecla by MSHA.
“Everything we’ve done ties to that process,” Baker said. Baker said the company expects to answer MSHA concerns and remove the potential violations notice.
Hecla is also contesting four citations issued by MSHA related to the 2011 deaths and injuries. If the federal agency concludes Hecla was negligent in how it operated the mine, the company faces up to $1 million in penalties.
