African Barrick COO resigns with immediate effect to "pursue other interests"

A surprise departure in the FTSE 250 this morning. African Barrick Gold's chief operating officer (COO) has upped and left (release).

Marco Zolezzi, who's been in the job since September 2010, has "resigned with immediate effect to pursue other interests."

For now, CEO Brad Gordon takes responsibility for the role. He commented on Zolezzi's resignation:

I would like to express my thanks to Marco for his significant contribution to ABG over the past 3 years. In that time Marco has overcome a range of challenges at the mines and leaves the business on a solid operational footing. We wish him well for his future endeavours.

London-based African Barrick is Tanzania's largest gold producer, with three mines, all of which are located in Northwest Tanzania.
