4.1.1 Introduction

Role within Group

Production in the West Africa Region is focused on our Damang and Tarkwa open pit mines in Ghana.

Tarkwa is the highest gold producer in the Gold Fields International portfolio, with a relatively robust NCE margin of 37%. As such, it plays a key role in supporting cash flow generation within the Group.

Operations

Our Damang and Tarkwa open pit mines are located within 30km from another in south-western Ghana.

Tarkwa is Africa’s largest open pit gold mine by production, with a substantial and well-defined Mineral Resource.

Damang, which is smaller, is in a period of transition with production expected to shift from the mature Damang pit to the adjacent Huni and Juno pits. These contain 14% of the mine’s current 4.1 million Mineral Reserves. The Huni Saddle between the Damang and Huni pits contain a further 23% of the Mineral Reserves. As such, our immediate focus is on stabilising production at the mine as we continue to investigate opportunities to capitalise on our large Mineral Reserve and Resource position so as to provide a production profile of 200,000 – 250,000 ounces per annum over the next 10 – 15 years. This exercise will also examine the potential for a push-back of the original Damang pit, which contains higher-grade ore than Huni and Juno at close to 2 grams per ton, as well as an underground operation.
