Gold Fields announced at the end of April 2010 that its Damang gold mine in Ghana is set to increase production, following the construction and commissioning of a new secondary crushing plant.
The plant will allow Damang to increase the average head grade to its mill by boosting the feed of harder, higher grade fresh ore and reducing the feed of softer, lower grade oxide ore. As a result gold production at the mine is forecast to increase up to 240,000 ounces a year in the medium term. Current production is some 200,000 ounces a year.
Gold Fields CEO Nick Holland says, “The installation of the secondary crusher is an important step toward the transformation of Damang into a long-life mine. It also contributes to our strategy of increasing attributable production from our West Africa region to at least one million ounces a year over the next five years.”
In order to feed the enhanced crushing and milling systems, exploration last year has been refocused to find additional higher grade ore on the mine’s property. These efforts have been successful and Damang is targeting a reserve of at least two million ounces in the medium term.
“Our aim is to extend the life of Damang by at least 15 years to 2025,” Holland says.
Process design of the secondary crusher project commenced in early 2009. Construction of the plant started in November 2009. The crusher was completed in April this year at a total cost of about US$12 million.
