Gold Fields (GFIJ.J: Quote), the world's fourth biggest gold producer, on Wednesday said it had been asked by authorities to shut its Kloof mine in South Africa after workers were killed in separate seismic events.

Gold Field's Kloof mine, located west of Johannesburg, was issued with instructions to stop operations by the government after two workers died early on Wednesday morning, while another worker died on Tuesday in separate tremors, with a magnitude of 1.5 on the Richter scale.

The entire mine is closed ... I cannot say when operations will resume, Gold Field's spokeswoman Marritt Claassens said.

Gold production at Kloof for F2008 was 821,000 ounces.

Nick Holland, Chief Executive Officer of Gold Fields said in a statement the accidents had come after a company record of 85 days without any fatal accidents at its South African mines. The group has four mines in the country including Kloof.

He said the company had suffered 16 deaths at its South African mines for its current fiscal year to date, compared to a total of 47 for the previous year.
