Hi iron, I belive SNEY stated somewhere that they intend to invest $250,000 in the Ghana project in exploration and at the same time expect a return of some where in the region of $960,000.
This gives you some idea of expected exploration and production costs of initial phase in Ghana.
I may be wrong but I have always thought the most expensive ounce of gold was the first one as it has cost all your initial investment and after that the recovery costs will go down untill you then need to upgrade equipment to increase recover and so it goes on until you are at a status quo.
