This is what I've always wondered especially re. Germany - is it possible to quantify how well a country has been prospected? How much is "resource poverty" a matter of low resource concentration vs (exploration)-absence? How do the economics change with changing energy and labor prices? What is the relationship between resources and the building of infrastructure, in terms of logistics and also permanent settling? Are many extraction and refining methods monopolized through patents or other mechanisms?
