I know an engineer who says anything is possible if you throw enough money at it. The costs associated with the development of the Pebble copper-gold-molybdenum project in Alaska come to mind when thinking in this vein.
The Pebble Partnership, a joint venture of Vancouver’s Northern Dynasty Minerals and Anglo American plc of London, UK, is shepherding the US$5-billion project toward production. The deposit is estimated to contain 80.6 billion lb of copper, 107.4 million oz of gold, and 5.6 billion lb of molybdenum.
Pebble is a deposit worth going after even if it takes and investment of $400 million and more to conduct work programs, research and comparative studies so far. Move than $100 million has been spent on environmental and socio-economic studies, resulting in a 27,000-page environmental baseline document.
This year’s budget is $107 million to be spent on engineering studies to complete a project description.
