Owning a gold mine, although potentially very profitable, may also be a source of ruin for many corporations. 95% of gold discoveries worldwide are not economically viable. It takes somewhere between 8 – 13 years to bring a gold mine from scratch into production, though this time frame can be halved in certain cases. Regardless of the amount of money that has had to be spent and the resources involved, many ventures have had to be scrapped at some stage due to unsolvable problems.
