CASE STUDY - ANGLO GOLD NAVACHAB

摘要

IN 1998-99, AngloGold Ashanti had planned a pit extension programme at its Navachab gold mine in Namibia that would support production until 2013. At that time, the plant treatment capacity was 170 t/h with an ore throughput of 1.4 Mt/y averaging 1.55 g/t gold. The low price of gold at the time persuaded the company not to proceed. But after a feasibility study, Navachab approved the Western Pushback, which made up half of the original expansion project. This extension of the main pit from 2000 to 2001 extended the life of the mine (LOM) from 2003 to 2005. In 2002-3, another feasibility project was launched to mine the Eastern Pushback. Through reduced costs and a strong gold price, this project was approved and it increased the LOM to 2013.
