A gold mine closing in California would cost the state about $15 million to close.

The mine, called SilverMineGold, would close in September.

It’s expected to reopen in early 2018.

SilverMineGold is operated by the New York-based Goldcorp, and the company said it has “excellent financial flexibility” in the event of an operating shutdown.

The company is expecting a $1 billion revenue and operating profit for 2018, which is up from the $700 million it earned in 2017.

The facility, located near Silver Lake, has a surface mine and an underground mine.

Goldcorp has been expanding its operations in California and other states.

In April, it said it plans to open up a copper mine near Los Angeles.
