Production. In 2005, the mine produced 904,000oz of gold, while production in 2006 fell to 444,000oz. In 2007-2008 average production was 500,000 ounces of gold annually. 3.25Mt of ore were milled in 2005 at a grade of 5g/t, as well as 23.1Mt at 0.58g/t being leached.
A gold mine was under severe pressure because the gold grade of the ore body it was mining had fallen by around 20 percent. The mine had increased ore-production volumes to try to offset the decline, but it was running into difficulties because this was overloading its leaching plant and incurring higher costs on energy, chemicals, and other major input costs.
exploration, depletion of deposits at existing mines, and changes in technology, public policies influencing mining, and mineral prices and production costs. In addition, and not part of this paper, mine-site exploration takes place at or in the vicinity of operating mines with the goal of extending the lives of these operations.

For many developing economies, low-cost labor was used as a means of comparative advantage. Mine plans that optimized through more labor were developed as it provided a cost advantage over production elsewhere in the world. However, many of these economies have been so successful in generating increases in
