The Olympic Dam Expansion, Roxby Downs, South Australia, is likely to see operations converted to open pit, one of the biggest of its type in the world. The expanded mine will produce around 40 million tonnes of ore to the new processing plant each year. It will produce significantly more metal in each of the commodity groups using similar technologies to those currently employed. The prefeasibility study will produce an estimate of the capital cost of the expansion.

Davis Langdon is providing a cost audit role which involves reviewing capital cost estimates prepared by a variety of other consultants for major infrastructure elements in terms of accuracy, completeness and consistency. Our prefeasibility role is likely to continue and potentially increase as the project commences construction.
