RE:RE:RE:RE:Ready to RunI am a smelter agnostic - it would certainly save money but it may add time. Like anything else it depends on how it is done. If GO can source a small smelter which is ready to go then it would make sense.
Having control over every aspect of the process, from mining to refining, is ideal as you eliminate the various fees involved in contract smelting as well as the costs of getting the concentrate to the smelter. Those savings go right to the bottom line.
One thing which has always impressed me about GO is that he understands that mining is, first and foremost, a business. It has to make a return on investment. If you can spend a little capital to significantly improve the ROI that's the move you should make.
