UPDATE 1-S.African minister blames Gold Fields bosses for mine woes

(Adds detail, background)

JOHANNESBURG, Aug 16 (Reuters) - Gold Fields' plan to cut jobs at its struggling South African mine fails to address "poor management," mining minister Gwede Mantashe said on Thursday, piling pressure on chief executive Nick Holland.

Gold Fields, which is due to report half-year results later, said this week it would cut 1,100 permanent jobs at its South Deep mine, sending its shares plummeting.

"Gold Fields is sitting on the second biggest gold deposits in a mine in the world," Mantashe, told Reuters. "Going for job cuts is the easy way out. The real problem is poor management."

South Deep, the company's last South African asset, has faced operational obstacles in a tough geological setting 3 km (2 miles) below the surface and has lost 4 billion rand ($284 million) over the past five years.

In response Gold Fields said on Thursday it would make further comments on the restructuring plan during its interim results presentation.

Holland said on Wednesday the job cuts were a "last-gasp measure."

Unemployment in Africa's most industrialized economy stands at more than 27 percent and job cuts are a hot political issue ahead of national elections next year.

Gold Fields, which unveiled a plan in February 2017 in an attempt to make its mechanized South Deep mine profitable, is the latest firm planning to cut jobs in the mining industry.

Earlier this month Impala Platinum said it would slash its workforce by around a third over two years. .

The 12,600 jobs are also on the line over a three year period as miner Sibanye-Stillwater seeks to acquire target Lonmin.

Mantashe, a former trade unionist, told Reuters he was engaging both Impala and Gold Fields over the planned lay-offs.

"We want to support them but they come to us after making these announcements. It is deviant behavior," said Mantashe. (Reporting by Joe Brock, additional reporting by Tanisha Heiberg Editing by Alexander Smith)
